摘要： An augmented reality system including a source and a contact lens display can be used to project information from the contact lens display onto the retina of the wearer's eye. The source provides energy to the contact lens display and operates at a source frequency. The source includes a source circuit including a conductive coil. The contact lens display includes a resonant circuit including another conductive coil and a capacitive circuit. The resonant circuit receives energy from the conductive coil of the source via a magnetic field inductively coupling the conductive coils. The contact lens display additionally includes a feedback circuit to adjust the capacitance of the capacitive circuit to control a resonant frequency of the resonant circuit. The feedback circuit can control the capacitive circuit to maintain the resonant frequency of the resonant circuit near the source frequency as the wearer's eye blinks.

摘要： An arrangement is described in which a number of tunable elements are tuned simultaneously. A signal representative of the desired tuning frequency is derived from a frequency synthesizer and applied in parallel to a number of staircase type comparators, each associated with a particular element to be tuned and providing an output on one of a number of output lines depending on the required tuning adjustment indicated by the comparator input.

摘要： According to an example embodiment, a device includes a resonant circuit configured and arranged to provide a peak current flow at a resonance frequency. A trimming circuit provides variable impedances to the resonant circuit and thereby changes the resonance frequency for the resonant circuit. A driver circuit is configured to generate a trimming signal that oscillates at a desired frequency. A switch circuit couples and decouples the driver circuit to the resonant circuit for driving the resonant circuit with the trimming signal. An amplitude detection circuit detects amplitudes for signals generated in response to the trimming signal being connected to the resonant circuit. A processing circuit correlates detected amplitudes from the amplitude detection circuit with different impedance values of the variable trimming circuit.
