A wireless switch comprises a mechanical oscillator, a mechanical impulse deliverer, a first array of magnets positioned on a planar surface, a first conductor, and a power management circuit. The mechanical impulse deliverer delivers a mechanical impulse to the mechanical oscillator when the wireless switch is switched. The first array comprises a one dimensional or two dimensional array of magnets. The first conductor comprises a first serpentine conductor. The power management circuit provides DC power as a result of relative motion due to the mechanical oscillator between the first array of magnets and the first conductor.

Wireless switch with multipolar electromagnetic generator

A method of sensing absolute position of a structure includes: generating a signal pattern to repetitively provide a changing voltage to each of two or more tracks of a sensor, capacitively coupling an electrode of the sensor to the tracks to determine a first electrode position along the tracks by detecting a first group of signals emitted in response to the signal pattern, moving at least one of the electrode and the tracks relative to another of the electrode and the tracks to result in a second electrode position along the tracks different from the first electrode position, and detecting a second group of signals emitted in response to the signal pattern with the electrode capacitively coupled to the tracks to determine the second electrode position.

Method of sensing absolute position of a structure using a capacitively coupled position encoder

One embodiment of the present invention comprises a sensor with a face having several tracks spaced apart from one another. One of these tracks has a first electrode and a second electrode separated by an electrically nonconductive gap. Also included is a detection device extending across the tracks to receive signals by capacitive coupling. Sensor circuitry electrically coupled to the tracks and the detection device is structured to generate a first number of bits from a sequential signal pattern applied to the tracks in accordance with an established sequence. The circuitry is also structured to generate a second number of bits as a function of a first signal and a second signal. The first bits and second bits represent a position of the detection device along the tracks with the first bits being more numerically significant than the second bits.
