    摘要： An optimizable beacon and method of using the same. The beacon has an onboard power source with a finite capacity. The system uses a capacitor bank to adjust the capacitance of the beacon, thereby maximizing the signal provided considering conditions, rather than simply using a theoretical value. With the specified capacitance being used, the beacon may be optimized in both a high and low power mode by driving the current to ensure the measured power is greater than or equal to a target. The system may also have a motion sensor to toggle the power off, or to a low-power mode, when the beacon is moving, and location measurements are not taking place. The optimization process may also consider the chemistry of the battery being utilized.

    摘要： Devices, systems, and methods for measuring a power consumption of a hot pluggable solid-state drives are described. An example method for measuring a power consumption of a solid-state drive communicatively coupled to a server backplane within a server chassis includes performing, by an adaptor, a power measurement to generate a value corresponding to the power consumption of the solid-state drive, and transmitting, using a wireless transceiver of the adaptor, the value to a recording unit, where a first end of the adaptor is coupled to the solid-state drive and a second end of the adaptor is coupled to the server backplane, and where the wireless transceiver, communicatively coupled to an antenna, is configured to operate using at least one wireless protocol.

    摘要： A method for distributed electrical power determination of at least one consumer connected to a voltage source via a voltage path, where a voltage measurement device determines a supply voltage of the voltage source at a voltage measurement point and at least one current measurement device determines a consumer current of the consumer at a current measurement point. The method comprises recording measured values of the supply voltage to determine a voltage curve of the supply voltage, recording measured values of the consumer current to determine a current curve of the consumer current, analyzing the measured values of the supply voltage and/or the measured values of the consumer current with an analysis function to determine voltage characteristics of the voltage curve and/or current characteristics of the current curve, and determining at least one power value taking into account the voltage and/or current characteristics.
