Abstract: A device for measuring electrical properties of electrical contacts within an electroplating apparatus has a disc-shaped structure like that of a wafer. Multiple conductive pads are formed to collectively circumscribe an outer periphery of the disc-shaped structure. Adjacently positioned ones of the conductive pads are electrically isolated from each other. The device includes a current source that supplies electric current at a first terminal and sinks electric current at a second terminal. The device includes measurement circuitry, having first and second input terminals, that determines a value of an electrical parameter based on signals present at the first and second input terminals. The device includes switching circuitry for connecting selected ones of the conductive pads to the first and second terminals of the current source and to the first and second input terminals of the measurement circuitry at a given time. The device also includes an onboard power supply.

Abstract: A method and system for measuring, determining and/or analyzing the cranking RPM of a vehicle is provided. The system measures the voltage of at least a portion of a vehicle's electrical system to determine high and/or low voltage time periods during at least a portion of a starting or cranking cycle. The time between high and/or low voltage points can then be used, along with the number of cylinders in the vehicle, to determine the cranking RPM of the vehicle. The system may include a load module and a control module that are removably coupled to one another in first and second configurations.

Abstract: A wave loss detection circuit includes: an anode of the diode receives a first drive signal, and a cathode of the diode is connected to a first end of the first resistor; a second end of the first resistor is connected to a first end of the first energy storage unit, a first end of the second resistor, and a first input end of the comparison unit; a second end of the first energy storage unit and a second end of the second resistor are connected to a ground level, and a resistance of the first resistor is less than a resistance of the second resistor; a second input end of the comparison unit is configured to receive a threshold voltage, and if a voltage signal received by the first input end is less than the threshold voltage, which indicates that a wave loss occurs in the first drive signal.

Abstract: An apparatus senses properties of a fluid. The apparatus has a pipe section, a valve, and an instrument. The pipe section has an envelope, through which a flow of the fluid is coupled between a tank of an electrical power device and a cooling device. The envelope is disposed about a longitudinal axis, and has a penetration disposed laterally, relative to the longitudinal axis. The valve is disposed within the one or more penetrations and has a closed position and an open position. The instrument is operable for the sensing of the fluid properties, and has a probe disposed in contact with the fluid through the valve in the open position.

Abstract: A partial discharge detection apparatus detects a plurality of discharge events, finds a time interval between the plurality of discharge events, and determines, where the discharge events occur at a time interval shorter than a threshold time, that a partial discharge has occurred within a metal enclosure, or determines, where the discharge events occur only at a time interval longer than the threshold time, that a discharge has occurred outside the metal enclosure. The partial discharge detection apparatus can thus readily distinguish between a partial discharge that occurs within the metal enclosure of a gas-insulated switchgear and a discharge that occurs outside the metal enclosure.

Abstract: Methods and systems are described for operating an imaging sensor, the imaging sensor including a multi-dimensional sensor. An electronic processor receives an output from the multi-dimensional sensor and transitions the imaging sensor from the low-power state into a ready state in response to a determination by the electronic processor, based on the output from the multi-dimensional sensor, that a first state transition criteria is satisfied and transitions the imaging sensor from the ready state into an armed state in response to a determination that a second state transition criteria is satisfied. In some implementations, the electronic processor operates the imaging sensor to capture image data only when operating in the armed state and prevents the imaging system from transitioning from the low-power state directly into the armed state.
