A method and apparatus for configuring a conductive plane for electromagnetic compatibility test of equipment or device. A positioning object is fixed above the plane of a conductive plane, the positioning object contacts an equipment under test (EUT), and the distance from the EUT to the conductive plane is equal to the distance from the positioning object to the conductive plane plus the thickness of the positioning object, thereby avoiding an error in measurement caused by a change in the distance from the conductive plane to the EUT during each test. In addition, the device is portable, and the conductive plane does not need to be grounded, and may be applied to a production site or field in which no grounding is available.

A method for recognizing the breakdown of an energy reserve device of at least two energy reserve devices of a device for protecting the occupants of a vehicle. The method includes: charging the at least two energy reserve devices to a test voltage level; ascertaining an ambient temperature of the at least two energy reserve devices; acquiring the (overall) capacitance of the at least two energy reserve devices; recognizing the breakdown of an energy reserve device as a function of a floating mean value, which is a function of the ascertained ambient temperature, for the (overall) capacitance and of the acquired (overall) capacitance; updating a floating mean value as a function of the ascertained ambient temperature and the acquired overall capacitance.

A testing device includes a testing socket and a reflector. The testing socket defines an accommodating space. The reflector is disposed in the accommodating space and has a plurality of reflection surfaces non-parallel with each other. The reflection surfaces define a transmission space.

A system for detecting anomalies in electrical wiring in a truck trailer. The system measures and compares current drawn from the truck tractor with the current drawn by a circuit at a particular trailer component or other location in the trailer wiring. If the two current measurements differ in excess of a predetermined threshold, the system can report a wiring anomaly. The location of the anomaly can then be determined by performing the operation for different trailer components thus testing multiple different branches of the trailer power distribution circuit, and using the results of these tests to determine that an anomaly is present, and possibly the location of the issue. The system may then send a notification to a remote computing device, to the truck tractor, or any combination thereof.

In order to quickly and accurately diagnose the failure of a coupling capacitor of an earth leakage detection device, voltage output unit (11a, OP1) generates a periodically changing periodic voltage and applies the periodic voltage to the other end of coupling capacitor (Cc) via first resistor (R1). Second resistor (R2) and third resistor (R3) are connected in series between a connection point between coupling capacitor (Cc) and first resistor (R1), and a predetermined fixed potential. Voltage measurement unit (11b) measures a voltage at a voltage dividing point between second resistor (R2) and third resistor (R3). Diagnosis unit (11d) determines whether or not coupling capacitor (Cc) is normal based on a voltage measured when switch (MRp, MRm, MRpp) is turned on in a state where voltage output unit (11a, OP1) outputs a fixed voltage.
