A noise eliminator to eliminate electrical hum from an amplified musical instrument is provided. An aspect provides a method of playing an electrically amplified musical instrument having a sound pickup system that is electrically grounded, including, but not limited to, the steps of: disposing a first connector to the skin of a player of the amplified musical instrument, wherein the connector has least two oppositely disposed sides, and wherein the first disposed side removably adheres to the skin of the player and the second disposed side permits an electrical connection to be made with the player's skin; disposing a second connector that is electrically connected to the electrical ground of the sound pickup system; and establishing an electrical connection between the first connector and the second connector. Other aspects are described and claimed.

Electrical hum eliminator

A remote device in accordance with the present invention includes an adaptive power receiver that receives wireless power from the wireless power supply by induction. The adaptive power receiver may be switched among two or more modes of operation, including, for example, a high-Q mode and a low-Q mode. By controlling the switching between modes, the amount of energy received by the adaptive receiver may be controlled. This control is a form of adaptive resonance control or Q control.

Wireless power control

An inductive power supply system includes a non-contact power supply for energizing a device. The inductive power supply system includes a communication system for enabling communication between a device and the system. The device transmits an identifier to the system. If the device does not have a transmitter, the system attempts to determine the type of device from a characterization of the power consumption by the device. If the device cannot be characterized, the inductive power supply system can be operated manually.

System and method for device identification

A wireless power transfer component with a selectively adjustable resonator circuit having a Q control subcircuit that varies the Q factor of the resonator circuit to control the amount of power relayed by the resonator circuit. The resonator circuit may be in the wireless power supply, the wireless power receiver, an intermediate resonator or any combination thereof. The resonator circuit may be actively configured based on a feedback circuit. The feedback circuit may sense a characteristic in the secondary circuit or elsewhere and actively operate the control subcircuit based on the sensed characteristic. The feedback circuit may cause the Q control subcircuit to change (reduce or increase) the Q factor when the sensed characteristic crosses a threshold value. The Q control subcircuit may include a variable resistor having a value that can be varied to adjust the Q factor of the resonator circuit.

Wireless power control system

A wireless power system for wirelessly transferring power to a remote device from a wireless power supply at a range of distances. Various embodiments are contemplated in which reflected impedance from the remote device can be reduced by reducing coupling outside the desired wireless power transfer path, allowing delivery of wireless power over a range of distances. For example, a system incorporating one or more of shielding, spacing, and offsetting may be used to reduce reflected impedance from the remote device. An adapter may also be used to extend the range of wireless power transfer.

Wireless power supply system

A charging system for an electric vehicle that assists in aligning a primary charging coil and a secondary coil. The system may include a wheel chock that raises the primary coil into alignment with the secondary coil when a tire enters the wheel chock. The system may include a primary that is recessed below the surface supporting the vehicle and is protected by a cover. The secondary coil may be protected and supported by a skid plate mounted to the vehicle. The system may include a charging circuit that is controlled by signals transmitted by a garage door opener transmitter or a garage door opener. The system may include sensors that detect the presence of an animal or object in the space between the primary coil and the secondary coil.

Inductive charging system for electric vehicle

An inductive charging system for recharging a battery. The system includes a charger circuit and a secondary circuit. The secondary circuit includes a feedback mechanism to provide feedback to the charger circuit through the inductive coupling of the primary coil and the secondary coil. The charger circuit includes a frequency control mechanism for controlling the frequency of the power applied to the primary coil at least partly in response to the feedback from the feedback mechanism.

System and method for inductively charging a battery

A power supply to provide electrical power to one or more loads. The power supply may include a resonant air core transformer to provide an adjustable and adaptable source of power to electronic devices. The power supply may include isolated primary-side circuitry and secondary-side circuitry. The primary-side circuitry may include control circuitry that, among other things, provides drive waveforms for the primary-side switching circuitry. In embodiments configured to produce AC output, the secondary-side circuitry may also include switching circuitry. The primary-side control circuitry may provide drive waveforms for the secondary-side switching circuitry. The secondary-side circuitry may include measurement circuitry that measures the current and/or voltage of the output and provides those measurements to the control circuitry through isolation circuitry. The control circuitry may adjust the drive waveforms for the primary-side and/or secondary-side switching circuitry as a function of the measured values.

Power supply

An inductively powered gas discharge lamp including both a power coil and a heating coils associated with each filament. The heating coils enable the filaments to be preheated before the starting voltage is applied through the power coils. The inductive power coils and the inductive heater coils are contained within the lamp envelope, allowing the lamp to be entirely sealed. A method of dimming the lamp also is disclosed. The lamp is dimmed by both decreasing the power applied to the power coils and increasing the power applied to the heating coils so as to prevent the arc from extinguishing under lower voltage conditions.

Inductively powered gas discharge lamp

A power supply for inductively powering a remote device has an inverter operating at an operating frequency and a primary coil. A phase comparator compares the phase of the voltage or current delivered by the power supply. If the phase relationship detected by the comparator is unacceptable, the inverter is disabled. After a period of time, the inverter is re-enabled, and the phase relationship is again determined.

System and method for powering a load

A food preparation system includes a non-contact power supply for energizing a cooking appliance. The food preparation system includes a communication system for enabling communication between a food appliance and the system. The appliance transmits an identifier to the system. If the appliance does not have a transmitter, the system attempts to determine the type of appliance from a characterization of the power consumption by the appliance. If the appliance cannot be characterized, the food preparation system can be operated manually.
