Abstract: A system, method, and battery control module for detecting negative contactor status of a battery, such as a high voltage vehicle battery, is disclosed. The method includes applying a constant current to a bipolar transistor element having a base, an emitter, and a collector, wherein the base is electrically connected to a first resistor and an analog-to-digital converter, the collector being electrically connected to a second resistor and a diode. A collected current is delivered by the collector, and the method includes injecting the collected current through the second resistor and the diode and into a negative contactor of a battery. The method also includes determining a resistance across the negative contactor of the battery. The system may include a battery having a negative contactor, the negative contactor having a switch side, and a battery control module in communication with the battery.

Abstract: An adaptor plug assembly includes an adaptor plug and a mobile device which has a receiving unit. The adaptor plug includes a housing having a first connection end from which two terminals extends, and a second connection end in which three receptacle holes are defined. The two terminals are connected to the second connection end. A coil is mounted to one of the two terminals and electrically connected to a micro controller which includes a calculating unit, a transforming unit and a wire-less transmitting unit. The transforming unit receives current inducted by the coil and transforms the current into a first signal which is sent to and calculated by the calculating unit to be a second signal which is transmitted by the wire-less transmitting unit to the receiving unit of the mobile device. A power unit is installed in the housing provides power to the micro controller.

Abstract: A bypass diode with a disconnection fault is identified. A test device includes: a signal introduction circuit that applies a disconnection position identification signal to between a positive electrode and a negative electrode of a solar battery string; and a fault calculating part that identifies the bypass diode with a disconnection fault on the basis of an AC component of a voltage between a frame ground and the positive electrode or an AC component of a voltage between the frame ground and the negative electrode when the disconnection position identification signal is applied.

Abstract: The present invention relates to device and method for detecting powered devices connected to a power source equipment in a Power over Ethernet system that provides multiple signal/power channels. A series of inspection signals including one discriminative signal is applied to the respective channels and response signals to the discriminative signal and other detection signals are compared in order to determine whether multiple channels are connected to one single powered device.

Abstract: Examples provided herein describe a female connector in a computing device that includes a plurality of sensors for determining if a male connector has established a proper connection with the female connector. To do so, in one example, each of the sensors is coupled to an actuator that protrudes into an aperture defined by an inner surface of the female connector. As the male connector is inserted into this aperture, the actuators are pressed down which activates the sensors. Furthermore, the actuators are arranged such that a first actuator is deeper within the aperture than a second actuator. Thus, if the male connector pressed down the first actuator but not the second, a computing device can determine that only a partially connection was made. By using at least two actuators arranged at different depths in the aperture, the computing device is able to detect a proper or improper connection.

Abstract: An inductive power transfer system comprises a transmitter circuit comprising a transmitter coil and a receiver circuit comprising a receiver coil spaced from the transmitter coil. The transmitter circuit is in the form of a Class E amplifier with a first inductor and a transistor in series between the terminals of a power supply. A first transmitter capacitance is in parallel with the transistor between the first inductor and a power supply terminal, a primary tank circuit in parallel with the first transmitter capacitance, the primary tank circuit comprising the transmitter coil and a second transmitter capacitance arranged in parallel with the transmitter coil, and a third transmitter capacitance in series with the first inductor between the first transmitter capacitance and the primary tank circuit. The second transmitter capacitance is selected such that a resonant frequency of the primary tank circuit is not equal to the first frequency.

Abstract: The service life of electrical equipment is predicted using a thermal history sensor mounted in the electrical equipment. At least one thermal history sensor is mounted inside or on an outer wall surface of electrical equipment. The thermal history sensor includes dissimilar metal joints, and the resistance values of the dissimilar metal joints change in response to the amount of intermetallic compound growing in the dissimilar metal joints due to the temperature inside the electrical equipment or of the outer wall thereof during operation. A determining mechanism periodically or irregularly monitors and stores in memory the resistance values of the dissimilar metal joints from the thermal history sensor, and uses the stored history of resistance values to predict the service life of the electrical equipment.
