Abstract: A solid state relay has independent charge pumps isolating each gate of a full bridge to achieve faster and proper gate turn on. The low side MOSFETs of the bridge are the current sensing device reducing loss and allowing a device controlled by the relay to achieve peak performance. Dynamic braking is achieved by the two low side MOSFETs being fully conducted and applying a load across the DC motor. Addition of a microprocessor to the device provides undervoltage sensing, current vs time readings, motor stall sensing, and motor temperature sensing. Motor temperature is detected by checking impedance of the motor at microsecond pulses to see if the motor is getting hot.

Abstract: A light-weight, portable photocuring device possesses a single multi-wavelength light emitting diode (LED). The single LED backed with a heat sink is driven by a driving circuit and controlled by a timing circuit. A temperature monitor can be included in a closed loop to feed back and control the driver. A multi-plexing device regulates the current to individual ports on the LED effecting the dies allowing the overall wavelength and intensity of the emitted light by the apparatus to be controlled. Lenses and/or light guides in the device act to further direct the light.

Abstract: A circuit for driving cold cathode tubes and external electrode fluorescent lamps uses only 19-26 watts of power. A steady state square wave oscillator generator sets a running frequency for the circuit. A high voltage inductor or high voltage/high frequency transformer in combination with a current limiting capacitor, the lamp and two low resonance value capacitors in series are set and tuned to the oscillation frequency to achieve resonance with the oscillator. The circuit requires an input that has been capacitively and inductively filtered to eliminate harmonic noise in and out of the input line. A thermal shutdown feedback circuit monitors temperature of the circuit. Further, a non-inductive or non-capacitive loading lamp detection feedback and a lamp disconnect driver eliminates false disconnects at start up due to cold bulbs and allows all lamps running on the circuit to continue operation if one is disconnected.

Abstract: The subject invention is a circuit for driving a cold cathode tube using a 110V power supply. Power is provided to the cold cathode tube through a direct current converter circuit. A resonance capacitor works in conjunction with the inductive storage device until the start resonance of the tube is attained as directed by a resistor/capacitor (R/C) network. Once the tube starts conducting, another R/C network maintains and controls the circuit at a run resonance. The main driver is an oscillator with a high side and low side MOSFET driver.

An inductive storage device in the circuit allows the LEDs to be driven with minimal voltage input.
