  2. Remote visual inspection - Wikipedia

    en.wikipedia.org/wiki/Remote_visual_inspection

    Remote are commonly used where distance, angle of view and limited lighting may impair direct visual examination or where access is limited by time, financial constraints or atmospheric hazards. RVI/RDVI is commonly used as a predictive maintenance or regularly scheduled maintenance tool to assess the "health" and operability of fixed and ...

  3. Crankshaft position sensor - Wikipedia

    en.wikipedia.org/wiki/Crankshaft_position_sensor

    In a diesel, the sensor will control the fuel injection. The sensor output may also be related to other sensor data including the cam position to derive the current combustion cycle, this is very important for the starting of a four-stroke engine. Sometimes, the sensor may become burnt or worn out - or just die of old age at high mileage.

  4. Advanced Video Coding - Wikipedia

    en.wikipedia.org/wiki/Advanced_Video_Coding

    A YouTube video statistics with AVC (H.264) video codec and Opus audio format In 2009, the HTML5 working group was split between supporters of Ogg Theora , a free video format which is thought to be unencumbered by patents, and H.264, which contains patented technology.

  5. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).

  6. MP4 file format - Wikipedia

    en.wikipedia.org/wiki/MP4_file_format

    Nero Digital uses DVD Video subtitles in MP4 files. The moov atom contains information about video resolution, frame rates, orientation, display characteristics, and more. It might be placed at the beginning or end of the file. In the latter case, the video file is not playable if the file is incomplete (truncated). [27] [28] [29] [30]

  7. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).

  8. Tire-pressure monitoring system - Wikipedia

    en.wikipedia.org/wiki/Tire-pressure_monitoring...

    To save energy and prolong battery life, many dTPMS sensors do not transmit information when parked (which eliminates spare tire monitoring) or apply a more power-expensive two-way communication which enables wake-up of the sensor. For OEM auto dTPMS units to work properly, they need to recognize the sensor positions and must ignore the signals ...

  9. HTML video - Wikipedia

    en.wikipedia.org/wiki/HTML_video

    The HTML specification does not specify which video and audio formats browsers should support. User agents are free to support any video formats they feel are appropriate, but content authors cannot assume that any video will be accessible by all complying user agents, since user agents have no minimal set of video and audio formats to support.
