   There is a pin in the connector that provides power for the scan tool from the vehicle battery, which eliminates the need to connect a scan tool to a power source separately. However, some technicians might still connect the scan tool to an auxiliary power source to protect data in the unusual event that a vehicle experiences a loss of ...

   en.wikipedia.org/wiki/Data_link_connector

   The data link connector (DLC) is the multi-pin diagnostic connection port for automobiles, trucks, and motorcycles used to interface a scan tool with the control modules of a given vehicle and access on-board diagnostics and live data streams. [1] Prior to 1996, many OBD-I data link connector's were in the engine compartment, usually near the ...

   OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.

   The useful power of this linear motor is =, being the power, the useful voltage (applied voltage minus back-EMF voltage), and the current. But, since power is also equal to force multiplied by speed, the force F {\displaystyle F} of the linear motor is F = P / ( V K v ) {\displaystyle F=P/(VK_{\text{v}})} or F = I / K v {\displaystyle F=I/K ...

7. VLF cable testing - Wikipedia

   en.wikipedia.org/wiki/VLF_cable_testing

   VLF cable testing (Very Low Frequency) is a technique for testing of medium and high voltage (MV and HV) cables. VLF systems are advantageous in that they can be manufactured to be small and lightweight; making them useful – especially for field testing where transport and space can be issues.
