    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: An apparatus is described herein. The apparatus includes a power transmit unit coil and an active shielding coil. The power transmit unit coil includes a set of main windings, positioned at a first location on a structure, to carry a first current in a first direction, wherein the first current is to cause an electromagnetic field to emanate from the power transmit unit coil. The active shielding coil is positioned at a second location on the structure and is to carry a second current in a direction substantially opposite the first direction wherein the second current is to cause a reduction of the size of the electromagnetic field.

    Abstract: Methods and apparatus for reducing energy consumed by drones during flight are disclosed. A drone includes a housing, a motor, receiver circuitry carried by the housing, and a route manager. The receiver circuitry is to receive airborne drone-generated wind data from an airborne drone located in an area within which a segment of a flight of the drone is to occur. The airborne drone-generated wind data is to be determined by an inertial measurement unit of the airborne drone. The route manager is to generate a route for the flight of the drone based on wind data, the wind data including the airborne drone-generated wind data. The route is to be followed by the drone during the flight. The route manager is to select at least one portion of the route to cause the drone to be at least partially propelled by wind to reduce energy consumed by the drone during the flight.

    Abstract: Systems, apparatuses and methods may provide for a wireless charging system that includes a charge circuit and a housing configuration having a substantially conical outer profile. Additionally, one or more charge coils may be positioned within the housing configuration and coupled to the charge circuit, wherein the one or more charge coils define a charge field direction that is perpendicular to the substantially conical outer profile. In one example, the housing configuration includes a plurality of segments arranged in a stacked configuration.

    Abstract: An apparatus is described. The apparatus includes a transmission coil and a power amplifier. The power amplifier includes a microcontroller and a memory. The memory includes instructions to determine electric current output of the power amplifier, perform a lookup of load reactance range based on target electric current, detect load impedance, calculate reactance based on the load impedance, determine if reactance is within the load reactance range, and adjust reactance shift compensation to bring the reactance within the load reactance range if the reactance is not within the load reactance range.

    Abstract: Technology for virtual reality device for avoiding collisions during a virtual reality experience. The virtual reality device comprises an accelerometer configured to sense an acceleration of the virtual reality device and a gyroscope configured to sense an angular velocity and orientation of the virtual reality device. Further comprising one or more proximity sensors configured to detect an object. A processor may be configured to receive data from the one or more proximity sensors and predict a potential collision between a user of the virtual reality device and the object detected by the one or more proximity sensors. An alarm may generate an alert regarding the potential collision.

    Abstract: An apparatus and related operating method of a mmWave WHMD, are provided. The apparatus utilizes beamforming information to determine direction information indicating a direction of a received signal from an external component that is connected to the apparatus via a VR data link. The apparatus selects and sets a current MCS that supports a data load of the VR data link. The apparatus, while maintaining the VR data link, determines a VR data link condition by a determination that a received signal is stronger or weaker than a predetermined signal strength level for the current MCS of the VR data link. When stronger, the processing circuitry is configured to signal a transceiver to widen a beam from a current beamwidth to a new wider beamwidth in a direction based on the direction information to maintain the current MCS and data load of the VR data link.
