Abstract: A system may include a resistive-inductive-capacitive sensor, a driver configured to drive the resistive-inductive-capacitive sensor at a driving frequency, and a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and configured to measure phase information associated with the resistive-inductive-capacitive sensor and based on the phase information, determine a displacement of a mechanical member relative to the resistive-inductive-capacitive sensor, wherein the displacement of the mechanical member causes a change in an impedance of the resistive-inductive-capacitive sensor.

Abstract: Some embodiments relate to power detector including a voltage sensor configured to detect a voltage of a load and a current sensor configured to detect a current of the load. The power detector also includes circuitry configured to introduce a phase delay between the detected voltage of the load and the detected current of the load, thereby producing a voltage measurement and a current measurement. The circuitry is also configured to multiply the voltage measurement and the current measurement.

Abstract: A system comprises a battery cell, control logic, and a battery drain latch circuit. The control logic is coupled to the battery cell and determines whether a battery pack has experienced a failure condition. The battery drain latch circuit is activated by the control logic, upon detection of a failure condition, to cause the battery cell to drain energy therefrom.

Abstract: An electronic load for testing stability of a power voltage of a power source under test (PSUT) includes a voltage supply device, a field effect transistor (FET), an amplification circuit, and a current sampling resistor. The amplification circuit includes a first input, a second input, and an output. The voltage supply device is connected to the first input. The second input is connected to a source electrode of the FET. The output is connected to a gate electrode of the FET. A drain electrode of the FET is connected to the PSUT. One end of the current sampling resistor is grounded, and the other end of the current sampling resistor is connected to the source electrode of the FET and the second input. The voltage supply device outputs a control voltage. The amplification circuit amplifies the control voltage and drives the FET using the amplified control voltage.

Abstract: An energy usage coordinator controls the energy usage of individual buildings of a group (or portfolio) of buildings in one or more load zones. These buildings have all contracted with an energy company which controls (directly or indirectly) the energy usage coordinator. By agreeing to lower energy usage during times of peak usage (when the energy company may otherwise have to pay very high prices on the spot or short term market), the owners or managers of the buildings receive a preferential energy rate from the energy company. Such a preferential rate may be in the form of a fixed rate reduction or a variable rate reduction. Alternatively, the energy company may determine that the energy is currently selling for twice what its building portfolio has contracted to pay for it so it requests some portion of the portfolio to reduce usage so that it can sell the excess/saved energy in the market.

Abstract: An electronic monitoring circuit for detecting a variation in the power or current absorbed by an electronic circuit under test is disclosed. The circuit includes an input terminal adapted to receive a pulse-width modulation control signal, a resistor having a first terminal connected to the input terminal, and a capacitor having a first terminal connected to a second terminal of the resistor. The output terminal is adapted to generate an output signal as a function of the value of the voltage drop at the ends of the capacitor, said output signal being representative of a variation of the pulse width of the pulse-width modulation control signal. The variation of the pulse width is a function of the power or current absorbed by the electronic circuit under test.
