Abstract: Methods and apparatus for high speed location determinations are disclosed. An example apparatus includes at least two coils arranged along a zone of interest to generate a magnetic field, and a sensor to measure a change in the magnetic field associated with the at least two coils as an object of interest moves within or into the zone of interest. The example apparatus also includes a processor to determine a position of the object of interest based on the measured change.

Abstract: A vehicular inductive power transfer system includes a power transmission unit and a power receiving unit. The distance between the units and the overall alignment of the units with respect to each other determines the overall efficiency of the energy transfer between the power transmission unit and the power receiving unit. Magnetic fields produced by the inductive power transfer system may exceed allowable standards or regulations for human exposure to electromagnetic fields. An inductive power transfer control circuit autonomously causes an actuator to position at least one of the power transmission unit or the power receiving unit in a three-dimensional space based on one or more measured power transfer parameters. Such positioning may occur while the vehicle is moving or stationary. The control circuit may further autonomously adjust one or more power transfer parameters to maintain magnetic field exposure levels at or below industry standards or governmental regulations.

Abstract: Techniques for focusing the energy radiated by a wireless power transmitting unit are described. An example power transmitting unit includes a transmit coil configured to generate a magnetic field to wirelessly power a device within an active wireless charging area. The power transmitting unit also includes a power generating circuitry to deliver current to the transmit coil to generate the magnetic field. The power transmitting unit also includes a patch array disposed in parallel with the transmit coil to reduce the strength of the magnetic field at frequencies outside of the operating frequency during operation of the power transmitting unit.

Abstract: Example wirelessly powered unmanned aerial vehicles and tracks for providing wireless power are described herein. An example apparatus includes a track section having a transmitter coil to generate an alternating magnetic field and an unmanned aerial vehicle having a receiver coil. The alternating magnetic field induces an alternating current in the receiver coil when the unmanned aerial vehicle is disposed in the alternating magnetic field.

Abstract: A sensor system can include a sensor coil and a sensor coupled to the sensor coil. The sensor coil can include coil portions that generate signals based on magnetic coupling induced in the coil portions by a receiving coil device (e.g., a NFC tag) and magnetic distortion induced in the coil portions by magnetic coupling of a power transmitting unit (PTU). The sensor can reduce the magnetic distortion induced in the first and the second coil portions by the PTU, detect the receiving coil device based the first and the second signals, and control the PTU based on the detected receiving coil device.

Abstract: Transmission power control methods and devices are described. In a transmission power control method, a specific absorption rate (SAR) is calculated based on a transmission power of the communication device and a proximity distance of the communication device with an external object. A time average specific absorption rate can be calculated based on the SAR. A power absorption budget value can be calculated based on the time average specific absorption rate and a time average specific absorption rate threshold value. Further, the transmission power of the communication device can be adjusted based on the power absorption budget value.
