Model Prototype: OXO Handheld Screwdriver
Model Prototype: OXO Handheld Screwdriver
This project focused on creating a low-fi 3D prototype of a potential design for a OXO electric handheld screwdriver with the following specifications:variable speed control you decide the mechanism/interaction and whether it is fluid or distinct settingsscrew-driver selection mechanism (either digital or non-digital your choice) allows you to automatically select and switch between either Phillips or flathead shape and five different sizes of each shape (for 10 total screwhead choices)screw-driver direction selection mechanism (non-digital) to either screw in or unscrewdigital readout (monochromatic, non-touch sensitive) of number of screws screwed and screws unscrewed for tracking your progress as a handypersoncan be used right or left-handedproduct dimensions are a minimum of 6 inches long and must be able to contain a rechargeable batteryproduct weight is between 11.5 poundsFor each of the feature criteria above, I came up with an idea for how I would implement it onto the prototype:Trigger pressure or wheel to control speedDouble wheel selection to change between head type and sizeA switch to control screw and unscrew optionsA digital number display to show the digital readoutA charging port and the end of the handleHere are my sketch ideas for how the features would look on the device:After sketching the prototype, I thought I had a pretty good idea of the layout of the controls but there were some things I realized as I was conceptualizing the design. There were a lot of features to implement onto the screwdriver that would be difficult to fit onto a handheld device so as I was sketching, I tried to consider space as a constraint. Another thing I noticed was that there was a big difference in readability between putting numbers side-by-side and one top of the other.PrototypeTo build my prototype I used cardboard and tape. I made the prototype larger than the actual size it would be so that I could clearly display the features and test the interface functionality with a user. Here is what the prototype looks like:AnalysisTo test this prototype, I sat down with a participant and asked them to screw in and unscrew a screw at a specified setting while vocalizing their thought process. The user was able to complete the task but there were a few features that were unclear.Features that were unclear to the user:Used the Phillips instead of a flat head on the screwThought the unscrew/screw switch was to activate the screw driverSuggested moving the placement of the controlsThings that went well:User was satisfied with the easy controlsWas easily held and comfortable in their handsAble to complete the task without major issuesThe prototype worked well to complete specified tasks but it was a challenge trying to fit all the features onto a small device. Another challenge was how to test a trigger that would rely on users pressure. Without outright telling the user how the device is reacting to their actions, it can be difficult to simulate. I would improve the layout of the controls by minimizing their size and moving the size selection to the handle. I would also use text instead of symbols to show the different screw head types because it seemed to confuse users during testing RELATED QUESTION What are POP materials when it comes to advertising?

How to Accurately Judge and Find Cable Fault
How to Accurately Judge and Find Cable Fault
Cable is an important part of signal equipment, but in the process of use, it is difficult for ordinary users to find the fault point, and they do not know what the reason is. Therefore, it is particularly important to quickly find the cable fault and judge the fault point. Wd-a10 cable fault tester is a set of comprehensive cable fault detector, which can test cable short circuit, cable disconnection, poor contact and other faults. By summarizing the previous experience, the factors affecting the test accuracy of cable fault tester are analyzed as follows. Since the accuracy of adjusting wave velocity is closely related to the accuracy of test, adjusting wave velocity has become the key to solve the problem. At least two conditions are required to accurately adjust the wave velocity: â‘ the length of the measured cable; â‘¡ There is a good core wire of the tested cable, which is not grounded. Adjust the measurement range without grounding. Connect a good core wire of the tested cable with a known length to the output port of the power cable fault tester and connect it with the red clip wire, the black clip wire and the ground, or another good core wire of the cable. Change the measurement range to match the actual length of the cable. If the actual length of the cable is less than 161.4m, the measurement range shall be adjusted to 161.4m; If the actual length of the cable is greater than 161.4 m and less than 322.8 m, adjust the measurement range to 322.8 m, and so on. The preset wave velocity is 200 220m / μ Set a wave velocity randomly between S and measure it as the wave velocity of the initial test. It is assumed that the wave velocity measured initially is 200 220 M / & mu; S is because the signal cables usually used are in this range. This step is very important. If this step is not set, the initial measured cable length is very different from the actual cable length, and it is difficult to adjust in the next step. After adjusting the wave velocity and measuring the distance of the fault point, compare it with the actual cable length. If the distance between the fault point displayed on the top of the screen is the same as the actual cable length, the original set wave speed, that is, the wave speed displayed on the screen is the actual wave speed of the cable. When testing any point fault of the cable, this wave speed can be used as the benchmark for testing; If the distance of the fault point displayed on the top of the screen is different from the actual cable length, you can simply adjust the wave speed with the cursor still, which can be large or small, so that the fault distance above the screen is the same as the actual length of the cable, then the adjusted wave speed is the actual wave speed of the cable. When testing the cable fault, you can use this wave speed as the benchmark.
Theory of Cable Fault Locator
Theory of Cable Fault Locator
The basic function of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems. It is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.

Functions of Professional Cable Identifier
Functions of Professional Cable Identifier
In order to quickly and accurately identify a specific cable from a bundle of cables, special instruments are needed, such as professional cable identification instrument. It is a compact instrument with relatively simple operation. So, what other functions should the cable identifier have? This is what Xiaobian wants to discuss with you today. Cable identification instrument is a special instrument used to identify a specific cable from a bundle of cables. It is a compact instrument, which is installed in an aluminum alloy box and consists of a signal generator, a receiver with sensor and wiring. In order to identify the cable reliably and accurately, it is necessary to add a special signal to the identified cable, which should be received by a special receiver. Using this characteristic, the cable to be found can be identified. The generator feeds periodic unipolar voltage pulses into the cable to be identified, which needs to be grounded at the far end to ensure that a large enough current flows through the cable. The system shall be designed so that the return current does not return from the same cable. This can be achieved. The direction of the pulse current fed into the cable can be used as an obvious identification standard. The outgoing current only passes through this cable, and all other adjacent cables flow through the return current, but their polarity is opposite. In addition to the actual difference in current direction, the current amplitude is also an identification feature. The outgoing current only passes through one cable, while the return current can pass through several cables, which means that the outgoing current is greater than the return current flowing through other cables. The task of the receiver is to detect the direction and magnitude of the current flowing through the cable. In order to achieve this purpose, the current sensor is used as a sensor, which is equipped with an amplifier and connected in series in the circuit. The sensor clamps the measured cable. The magnetic field generated by the current flowing through the cable induces a voltage in the coil of the sensor. The polarity of the voltage is determined by the current direction and the direction of the sensor coil. In order to obtain the voltage polarity with obvious current direction, all cables in a bundle shall be tested in the same correct direction. The voltage induced in the sensor coil is displayed in the meter. If the sensor is connected in the above way, the pointer swing direction can display the current direction, that is, only the cable with current flowing out deviates to one side, and this is the cable to be found. All other cables only flow return current, the pointer deviates to the other side, or there is no pulsating current, and the pointer does not deflect. The amplifier regulator on the receiver can adjust the signal strength. What we need for professional cable identification instrument is, on the one hand, of course, to have good accuracy. If the accuracy is not enough, we will use it in vain. If it is not accurate, it will affect the later stage. In addition to accuracy, it is necessary to ensure the service life. When an ordinary voltage current ratio meter type grounding resistance meter (commonly known as grounding megger) is used to measure the grounding resistance, the grounding device passing through the tower shall separate the grounding down lead from the tower for measurement; Through the grounding device of non prestressed reinforced concrete pole, the measurement shall be carried out after the grounding down lead is separated from the lightning conductor from the top of the pole. In the initial state of the system, press the setting key of the DC resistance tester to enter the setting function state, set the material option to unknown, set the measurement mode to resistance, set the working mode to standard, set the measurement speed to standard, and press the return key to return to the initial state of the system.
Cable Grounding Troubleshooting and Precautions
Cable Grounding Troubleshooting and Precautions
There are three main reasons for cable grounding fault. First, cable manufacturing defects are unqualified products; Second, poor operating environment, natural aging and external damage; Third, the installation is not standardized and the wiring is rough. There is only one root cause of grounding fault --- the insulating material of the cable. China's large-scale ground power stations are generally located in the West. These places are generally desert, saline alkali land, large temperature difference in the daytime, serious rat damage and very humid environment. For cable buried laying, the filling and excavation requirements of cable trench are relatively high; The operating environment of the distributed power station cable is no better than that of the above ground. The cable will bear a very high temperature, which is measured and controlled by technicians. The roof temperature can even reach the high temperature of 100-110 ℃. The fire and flame retardant requirements of the cable and the high temperature have a great impact on the insulation breakdown voltage of the cable. Therefore, the following points should be considered in the type selection design: 1. The insulation performance of the cable 2. The moisture-proof, cold proof and weather resistance of the cable 3. The heat-resistant and flame-retardant performance of the cable 4. The laying mode of the cable 5. The conductor material of the cable (copper core, aluminum alloy core and aluminum core) 6. The Section specification of the cable
Principle and Application of Cable Oscillation Wave Test
Principle and Application of Cable Oscillation Wave Test
1、 Principle of cable oscillation wave test through cable oscillation wave test can not only diagnose the overall insulation of cable, but also test partial discharge and locate defects. The principle is LCR damping oscillation principle. On the basis of completing the cable pressurization, a damping oscillation voltage wave is formed through the built-in high-voltage reactor, high-voltage solid-state switch and the test cable. A sinusoidal voltage wave similar to the power frequency is applied to the test cable to excite the partial discharge signal at the potential defect of the cable. Based on the pulse current method, the partial discharge signal is detected with high sensitivity, and the detection, acquisition and upload of partial discharge signal are completed with high-speed data acquisition equipment. The single test process is about one minute, with high test efficiency and no damage to the tested cable. On the basis of obtaining the partial discharge data, the data analysis software automatically completes the cluster analysis and traveling wave positioning, which is convenient for users to comprehensively evaluate the cable state. 2、 Purpose: the cable oscillation wave test standard passes the field test to check the insulation condition and internal partial discharge condition of the cable without damaging the insulation of the cable itself, so as to evaluate the cable insulation. The high voltage unit of cable oscillation wave test can generate oscillation wave high voltage signal, and the high voltage generator can generate any high voltage of 0-30kv; For the partial discharge test device with no blind area from the partial discharge signal, there is no blind area, and it can detect the cable below 250m for partial discharge test; One laptop can be used for control; External safety control units such as operation software (Chinese / German / English version); Analysis software (Chinese / German / English version); A 7.5m high-voltage connecting line without partial discharge, with anti falling off safety design; The partial discharge under system voltage is less than 1pc III. cable oscillation wave test case analysis through the above understanding, let's talk about examples below, so that you can better understand its actual field use. Firstly, connect the test line according to the instructions, and then turn on the power supply. The waveform diagram during the test is as follows: through a waveform analysis, we found a damaged gap in the outer sheath at about 132M in the field survey, which is the cable insulation damage caused by external construction force. After disassembly, the main insulation is damaged

How to Distinguish Between Phase Voltage and Line Voltage
How to Distinguish Between Phase Voltage and Line Voltage
What is the phase voltage? What is the line voltage? What are the relations and differences between them? This paper will interpret them one by one.Triangular connection and star connection without leading out neutral point have three terminal wires, three-phase system, three live wires, 380V, line voltage. The star connection leading out the neutral line includes three live lines, a total of four power lines, three-phase four wire system, one fire, one zero, 220V phase voltage. The line voltage is the vector sum of the phase voltages of two phases. Line voltage = 2 * phase voltage * cos30 degrees = root number 3 * phase voltage, i.e. 380 = root number 3 * 220Many times, the phase voltage is generally understood as the voltage between phases, that is, 380V, while the line voltage is understood as 220V, which is just the opposite.Concept:Phase voltage is what we often call 220V household voltage. The voltage between zero line and live line becomes phase voltage. In fact, all in our home are phase voltages.Line voltage refers to the voltage of any two live lines, that is, 380V, which is actually the phase voltage. The phase voltage is 220V and the line voltage is 380V.Relationship differences:In the process of long-distance power transmission, the higher the voltage, the lower the loss, which is why the country has been studying ultra-high voltage power transmission (I = u / R). Generally, the high-voltage power is transmitted to the end user, and then reduced to 220V / 380V through the step-down transformer to supply different users.For the three-phase four wire power network, the voltage between any one of the three phase lines and the zero line becomes the phase voltage; The voltage between any two of the three phase lines becomes the line voltage. The phase difference of the three-phase voltage is 120 degrees. The line voltage is the vector sum of the phase voltages of the two phases. The relationship between the line voltage and the phase voltage is: line voltage = 3 times the phase voltage of the root number, that is, 380V = 3 times the 220V of the root number (sorry, the mathematical root number 3 of the formula cannot be uploaded in the headline).The two-phase electricity is connected to the running three-phase motor, and the motor can still work. This is what we often say that the motor runs without phase, but it is easy to burn the motor in this way. After the three-phase motor with triangular connection is out of phase, the output power of the motor will also become two-thirds of the original three-phase power supply, and the other two windings only provide one-third of the power, resulting in three-phase imbalance, current imbalance and current imbalance. Of course, the motor is easier to burn out.After the star connected three-phase motor is out of phase, the motor output power is completely provided by two windings, and the load increases by 50% respectively. The other winding does not work, so the working current is unbalanced and the motor is easy to burn out. When two-phase electricity is connected to the stopped three-phase motor, the motor cannot be started. For single-phase motor, after connecting two 380V phase lines, the voltage becomes 380V, originally 220V. In this way, the voltage increases and the motor must be burned out.
How to Choose High-quality  Ip Cctv Tester
How to Choose High-quality Ip Cctv Tester
If you are installing an analog surveillance camera system, you might want to consider taking a few handy cables with you. Later on this blog post, we will delve into the types of cables you will encounter when you start a hard-wired surveillance camera system. Let's start with Ethernet cables, the most common cables you need for your hard-wired surveillance camera system.For an analog HD / TVI surveillance camera system you need Siamese RG-59 cables. With these cables, you can power your surveillance camera and receive video information from the camera when only one cable is running. Use a Siamese replacement cable for your surveillance cameras, use it for your computer, use a Siamese replacement cable for your printer or use it when your network needs something different.By using PoE switches and injectors, IP cameras can supply and transmit video with a single cable, reducing cable costs compared to CCTV. CCTV uses coaxial cables, while IP cameras use the standard Cat 5E and Cat 6 network cables.IP cameras work by twisting a pair of coaxial cables for a wireless connection. One of the advantages of IP cameras is that they can be powered by a pair of twisted Ethernet cables, eliminating the need to lay electrical wires. IP cameras have an aVision capability of IP that surpasses analog systems.Analog cameras, for example, require a separate cable to control pan, tilt and zoom functions. They are also vulnerable to security breaches as the feed can be intercepted and the recording device stolen. IP cameras can accept power, video, audio and PTZ controls and control the signal via a single cable.The cabling you want to install depends on what you have in the surveillance camera system and what type of camera you want to choose. Mounting a surveillance camera on the outside of a house may seem like a daunting task, but it is the only way to get a camera to work the way it is designed. When viewing a PTZ camera, you want to monitor the live video feed over a large area and be able to zoom in and see more detail, especially in the case of a security guard overlooking a parking lot.There are two types of video surveillance systems: CCTV (closed circuit television, also known as analog) and IP (also known as network cameras ). IP cameras are digital cameras that send signals over a cable and are stored in a network. They are the biggest technological advance in cameras ever produced.CCV systems convert the video signal into a format that can be used for television (video recorders and DVRs). IP cameras convert video signals into IP packets which are transmitted to a storage device such as a server (NAS) or stored on board the camera over a data network (Internet network). High-quality HDCVI cameras (Solid Copper Coax Roll-off) can transmit video up to 1,600 ft.The recorded H.264 video file can't be played in Windows Media Player when it is played by the tester. The video stream is not displayed on the tester if the data rate is close to 0 KB / s. For this reason, the video file must be converted to MP4 format before it can be played in the test.Some private security cameras have optical zoom lenses (digital zoom) that trim and enlarge the camera while shooting. The more megapixels the camera sensor has, the more you can zoom in to see things better. The 1080p is the standard resolution of the cameras we tested and will benefit from a model with a higher resolution sensor.The warranty does not cover operating system errors caused by third-party apps. You can use the built-in Chrome or Firefox web browser to download the camera app and camera information. We recommend that you use an existing VLC to play the video clips.Our security camera testers are designed to facilitate the installation, maintenance and testing of security cameras. A shopper who bought a CCTV camera tester used it to test his camera before he started installing it in his home. A closed circuit TV tester is a handy tool for professional installers of CCTV security systems and do-it-yourselfers to set up and configure CCTV cameras from any source.CCTV testers feature a colour LCD screen, video port, rechargeable lithium batteries and several types of colour bars for signal output. The Cat6 cable is the most widely used cable in the world and Balun is widely used, but wearing analog video destroys clarity, so the passive Balun should be used according to the manufacturer's recommendations. For a fast and dirty workshop, check the analog camera and look at the test card to show clarity outside the camera.The Evertech screen is not the best, he writes, but it's fine given the cost. A reviewer looking for a CCTV tester IP camera and monitor kit is stating that it comes at an unbeatable price, considering he only needs it for a single home security setup.The Koolertron GH iPCT98, which is hard to beat even for $300, runs on Android and iOS apps, meaning that you can download and install a word processor or calculator program and reduces the number of devices a technician has to take to the field.The vast majority of private surveillance cameras now have mobile apps, and many are focused on how to do it remotely. Web portals offer more flexibility to access your videos and notifications. Another aspect of the functionality that should not be overlooked by a CCTV tester is the ability to work with analog IP cameras.Additional features vary from camera to camera, but our top picks offer enough variety to separate them from the rest of the competition. Remember that these cameras are designed to help you keep track of what is happening around your home.
