    Abstract: Techniques for integrating a plurality of radio antennas in an electronic device are described. An example of an electronic device includes a display housing with a display screen and top bezel disposed above the display screen, and a plurality of components disposed in the top bezel. The plurality of components include a first cellular communication antenna disposed on a first side of the top bezel, and a second cellular communication antenna disposed on a second side of the top bezel opposite the first side. The plurality of components also include a first WiFi antenna disposed adjacent to the second cellular communication antenna, and a second WiFi antenna disposed adjacent to the second cellular communication antenna on an opposite side from the first WiFi antenna.

    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: 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.

    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.
