Abstract: An apparatus and method for testing a temperature sensor in a vehicle is provided. The apparatus includes a power device. The power device is configured to receive a power signal and to filter the power signal to generate a filtered power signal. The power device is further configured to compare the filtered power signal to a first threshold and to test the temperature sensor based on the comparison of the filtered power signal to the first threshold.

Abstract: An offline power supply includes a power supply circuit including a primary-side circuit for connecting to a first power source, a secondary-side circuit for connecting to a load, and a transformer connecting the primary-side circuit and the secondary-side circuit. A switch operates to selectively connect the primary-side circuit to the first power source. A second power source is charged during operation of the power supply circuit. A controller powered by the second power source has at least one input, and an output to selectively operate the switch based on the at least one input.

Abstract: A dual-charger system operable to facilitate charging a battery with energy regulated by two chargers connected in parallel to the battery where one charger operates according to a voltage regulation mode and the other of the two chargers operates according to a current regulation mode.

Abstract: An inverter configured for use within a vehicle to power consumer electronic devices and other types of devices requiring single-phase, AC energy. The inverter may include a network interface or other type of the connection to a vehicle data bus or other message exchange system in order to communicate with an electronic control unit (ECU) or other feature included within the vehicle to monitor and control energy consumption by one or more vehicle subsystems.

Abstract: A system and method for controlling the output voltage of a power supply that includes a control section and an interconnect section having an output point. A voltage regulator provides a control section voltage, and a current measurement device measures a control section current and generates a current signal. A controller receives the current signal and a voltage command signal representing a desired output voltage at the output point of the interconnect section. The controller generates an adjusted voltage command signal based on the voltage command signal representing the desired output voltage, the current signal, a control section internal resistance and an interconnect section external resistance. The voltage regulator receives the adjusted voltage command signal and provides a control section voltage based thereon in order to supply an output voltage at the output point that is substantially equal to the desired output voltage.

Abstract: An energy-on-demand vehicular ignition system with a programmable re-striking and minimum single-strike energy output whereby at idle engine speed and lowest load, each coil will be re-struck or discharged the maximum number of times permitted by the coil design within a limited time interval representing the beginning of the combustion event and occurring within 0-2% MFB of the ignitable air fuel mixture within the combustion chamber. The system strategy also includes programmable re-striking whereby the system will default to a single-strike at conditions above a predetermined range of operating conditions, in particular, at a particular engine speed condition and a particular engine partial load condition. In between the conditions at (i) idle engine speed and lowest load on the one hand and, (ii) a predetermined engine speed and partial load condition.
