摘要： A testkey includes two switching circuits and two compensation circuits. The first switching circuit transmits a test signal to a first DUT when the first DUT is being tested and functions as high impedance when the first DUT is not being tested. The second switching circuit transmits the test signal to a second DUT when the second DUT is being tested and functions as high impedance when the second DUT is not being tested. When the first DUT is not being tested and the second DUT is being tested, the first compensation circuit provides first compensation current for reducing the leakage current of the first switching circuit. When the first DUT is being tested and the second DUT is not being tested, the second compensation circuit provides second compensation current for reducing the leakage current of the second switching circuit.

摘要： A system for autonomously validating the topology information of an electrical power distribution system is provided. For example, the system includes a group of meters previously determined to be connected to the same transformer of an electrical power distribution system. The group of meters is configured to perform family check periodically or upon request and to identify orphan meters in the group. The identified orphan meter can contact a community device communicatively connected to meters in more than one group to request a community check. The community device performs the community check by contacting meters in other groups of meters and obtain their family signature data. The community device further determines whether the orphan meter belongs to a new family based on the voltage data of the orphan meter and the family signature data of other groups. The orphan meter can report the community check results to a headend system.

摘要： Embodiments described herein relate to a method for modifying transmission line characteristics. The method may include: making a first determination of a null frequency of an input signal to a transmission line; performing an analysis to make a second determination of a wavelength of the input signal using, at least in part, the null frequency; making a third determination, based on the analysis, of a half wavelength of the input signal; calculating, based on the half wavelength, a total stub length; and adding a trace to a stub associated with a via, wherein the stub and the trace are a length that is at least a portion of the half wavelength of the input signal.

摘要： A backup battery charging system for a building management system is disclosed. Components of the charging system include an analog power converter, a voltage feedback loop and a current feedback loop. The feedback loops each include at least one digital resistor. The system panel, in turn, includes at least one microcontroller that controls the building management system and also controls the charging system. The charging system is “software defined,” in that the microcontroller controls the charging system by updating the digital resistors in the feedback loops to control the analog power converter. In one example, the building management system is a fire alarm system controlled by a fire control panel as the system panel.

摘要： The present disclosure presents techniques to facilitate improving operation of an electrical system, which includes a bus structure that cascades multiple electrical devices. The bus structure includes a first outer conductive layer implemented as a positive layer; a second outer conductive layer implemented as a negative layer; a first intermediate conductive layer neighboring the first outer conductive layer; a second intermediate conductive layer neighboring the second outer conductive layer; and a third intermediate conductive layer neighboring the second intermediate conductive layer, in which the third intermediate conductive layer is implemented as an inter-device layer that facilitates electrically coupling at least two of the electrical devices in series. The first intermediate conductive layer is implemented as a negative layer and the second intermediate conductive layer is implemented as a positive layer to facilitate reducing stray inductance and/or increasing stray capacitance introduced in the electrical system during operation.
