Abstract: An apparatus includes a housing for an electronic circuit. The housing includes at least three planes that form a structure to house the electronic circuit. At least one channel is formed along at least one of the three planes to provide a waveguide in the housing for wireless communications. A wireless communications module communicates via the waveguide to control the electronic circuit enclosed in the housing.

Abstract: Methods, apparatus, systems and articles of manufacture to efficiently transfer power wirelessly are disclosed. An example apparatus includes a feedback loop to when a second current value is greater than a first current value, change a direction value, the second current value being obtained after the first current value; when the second current value is less than the first current value, maintain the direction value; and a summer to when the direction value corresponds to a first direction value, increase a reference signal by a step size; and when the direction value corresponds to a second direction value different than the first direction value, decrease the reference signal by the step size.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to measure a resonant sensor based on detection of group delay. An example apparatus includes a modulation manager configured to query the resonant sensor with a modulated signal including a frequency; and a resonance determiner configured to determine a resonance frequency of the resonant sensor based on a group delay associated with the resonant sensor and the frequency.

Abstract: Circuits for controlling a plurality of LEDs connected in series are disclosed herein. The circuit includes a plurality of switches, wherein each switch is connectable between the anode and cathode of one of the plurality of LEDs. Each of the switches has a first state wherein current does not pass through the switch and a second state wherein current passes through the switch. The circuit also includes an input for receiving data to program the switches and a data line for transferring data between a circuit controlling second LEDs that are connected in parallel with the first LEDs and the circuit. In addition, the circuit includes a data output for transferring data to other circuits controlling third LEDs that are connected in series with the first LEDs.

Abstract: An inductive structure includes a power coil and a data coil. The data coil is substantially centered within the power coil. A first portion of the data coil conducts current in a first direction. A second portion of the data coil conducts current in a second direction opposite the first direction. The first portion of the data coil is connected at a node to the second portion of the data coil. The node is coupled to a ground.
