Abstract: A battery charger device and controller is provided. The battery charger includes a DC/DC converter operative to convert an input current and an input voltage to an output current and an output voltage. The controller is configured to determine whether the input voltage is between a minimum voltage and a maximum voltage and dynamically adjust the output current based on the determination that the input voltage is between the minimum voltage and the maximum voltage.

Abstract: A temperature compensated warning light includes banks of high output light emitting diodes (LED's), one or more drivers connecting the LED banks to a control processor, and a temperature sensor thermally coupled to the LED's to provide a temperature signal indicative of the temperature of the LED's to the processor. The processor pulse width modulates a base frequency signal to the LED's in such a manner as to maintain a constant brightness of the LED's as the temperature of the LED's varies. The processor also monitors supply voltage and further varies the pulse width of the base frequency signal to compensate for supply voltage variation. The base frequency signal is modulated by a flash signal to create desired flash patterns.

Abstract: An integrated multifunction flasher system includes a pair of light units, each light unit housing an LED array, LED switches, and a programmed controller within an enclosure. The controllers of the pair of units are interconnected and are additionally connected to the turn signal wiring, the backup signal wiring, and to a manually operated switch. The controllers sense the operation of the turn signals, the backup lamps, and the manual switch and cooperate to generate flash patterns which parallel the turn and hazard flasher signals and which generate alternating strobe patterns in response to activation of the backup lamp or closure of the manual switch.
