Abstract: Techniques for focusing the energy radiated by a wireless power transmitting unit are described. An example power transmitting unit includes a transmitter 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 transmitter coil to generate the magnetic field. The power transmitting unit also includes a shield disposed around the transmitter coil to reduce the strength of the magnetic field outside of the active wireless charging area.

Abstract: In a wireless charging device that includes a resonator having coil windings, a magnetic field can be generated by the resonator. The wireless charging device can include a feed point connected to an inner winding of the coil windings of the resonator. The resonator can inductively couple with a power receiving unit such that the an outer winding of the coil windings limit Eddy current generation in one or more conductive surfaces positioned adjacent to the power receiving unit. The feed point can be selectively connected to the inner winding of the coil in a first mode of operation and the outer winding of the coil in a second mode of operation. The inner winding can have a larger current than the outer winding.

Abstract: Techniques for proximity sensing in a wireless power transmitter in a system, method, and apparatus are described herein. For example, an apparatus may include a transmitter coil configured to generate a magnetic field. The apparatus may also include a controller configured to reduce a strength of the magnetic field based on a proximity detection of an object.

Abstract: Systems and methods for sensing angular displacement between body segments of users include disposing an electromagnetic transmitting sensor about a first body segment and an electromagnetic receiving sensor about a second body segment. Data related to the magnetic field coupling between the transmitting and receiving sensors can be captured for determining the angular displacement between the first and second body segments.

Abstract: Examples are disclosed to track sport implements and/or objects of interest. An example apparatus includes a first coil to generate a first magnetic field having a first vertical component with a zero magnitude along a first line of interest and a second coil partially overlapped with the first coil, where the second coil is to generate a second magnetic field. The example apparatus also includes a sensor to measure a magnitude of the first magnetic field in the first line of interest and a processor to determine an object of interest has crossed the first line of interest based on the magnitude of the first magnetic field measured by the sensor.

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 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: Technologies for detecting a physical assault against a user include one or more clothing sensor modules coupled to a garment of the user. Each clothing sensor module is configured to produce sensor data indicative of the removal of the garment from the user and determine whether a physical assault is presently occurring against the user using an assault detection model with the sensor data as an input to the assault detection model. In response to a determination of the physical assault against the user, the clothing sensor module is configured to alert a trust party.
