摘要： An inductively powered gas discharge lamp assembly having a secondary circuit with starter circuitry that provides pre-heating when power is supplied to the secondary circuit at a pre-heat frequency and that provides normal operation when power is supplied to the secondary circuit at an operating frequency. In one embodiment, the starter circuitry includes a pre-heat capacitor connected between the lamp electrodes and an operating capacitor located between the secondary coil and the lamp. The pre-heat capacitor is selected so that the electrical flow path through the pre-heat capacitor has a lesser impedance than the electrical flow path through the gas of the lamp when power is applied to the secondary circuit at the pre-heat frequency, and so that the electrical flow path through the pre-heat capacitor has a greater impedance than the electrical flow path through the gas when power is applied the operating frequency. The primary circuit may include a tank circuit for which the resonant frequency can be adjusted to match the pre-heat frequency and the operating frequency.

摘要： An inductive power supply that maintains resonance and adjusts duty cycle based on feedback from a secondary circuit. A controller, driver circuit and switching circuit cooperate to generate an AC signal at a selected operating frequency and duty cycle. The AC signal is applied to the tank circuit to create an inductive field for powering the secondary. The secondary communicates feedback about the received power back to the primary controller. The power transfer efficiency may be optimized by maintaining the operating frequency substantially at resonance, and the amount of power transferred may be controlled by adjusting the duty cycle.

摘要： A method of controlling an inductive charging system on those occasions in which the combined power requests of a plurality of secondary devices exceed the power capacity of the power supply. The method includes at least one of (a) powering each device at a level below its requested level, (b) powering each device sequentially, and/or (c) powering each device in a repetitive pattern (e.g. time multiplexing). Also disclosed is a method of controlling an inductive charging system at least partially as a function of information received from the power management unit (PMU) of each secondary device.

摘要： The present invention provides a load used for communication in a remote device having a dynamic communication load configuration. In one embodiment, the dynamic communication load configuration varies as a function of a characteristic of power in the remote device. The remote device toggles between load configurations to communicate with the inductive power supply. A sensor in the remote device detects a characteristic of power in the remote device and configures the communication load based on the sensor output. In another embodiment, the remote device adjusts the dynamic communication load configuration in the remote device in response to a failure to receive a response from the inductive power supply.

摘要： A system for automated testing of the lamp filaments has an ohm meter. The ohm meter ís used to determine the resistance of the lamp filament prior to energizing the lamp. A multiplexer switches the ohm meter from one lamp filament to the next so that the lamp filaments are quick y and accurately tested. After the cold resistance of the lamp filaments is measured, a power supply energizes the lamp filaments.
