Abstract: Techniques for performing one or both of gesture recognition and biometric monitoring with an electronic device are disclosed, where the electronic device has a wireless communications capability using beamforming techniques and includes a plurality of millimeter wave antenna modules. Each module includes at least one transmit antenna and at least one receive antenna, operable in one or more frequency ranges not less than 20 GHz, the receive antenna coupled with a first branch configured to receive H-polarized signals and a second branch configured to receive V-polarized signals. Performing one or both of gesture recognition and biometric monitoring includes detecting a presence and motion of a reflective object or anatomical feature by determining a relationship between received H-polarized signals and received V-polarized signals for two or more receive antennas as a function of time.

Abstract: Methods, systems, and devices for wireless communications are described. An exemplary method includes receiving a signal corresponding to a frequency band, scanning for communications activity within the frequency band, wherein scanning for communications activity within the frequency band comprises performing a correlation calculation on samples of the signal, and determining whether to attempt a connection establishment within the frequency band based at least in part on the correlation calculation on samples of the signal. When the scanning identifies an indication of activity, a scanning device may attempt to establish a connection with a base station within the frequency band. When the scanning identifies an indication of no activity, a scanning device may refrain from attempting to establish a connection with a base station within the frequency band, and may perform the correlation-enhanced frequency scanning on a different frequency band.

Abstract: Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for object detection and three-dimensional reconstruction of objects using coordinated beam scanning. The disclosed techniques teach coordinated beam scanning that can be used for both detecting proximity to personnel in addition to detecting objects for three-dimensional object reconstructions. The techniques form one or more millimeter wave beam that can be electronically steered by adjusting the phase of the various antenna elements. The techniques can include saving the plurality of grid points for which the object is detected to a memory for detecting a range to the object for Maximum Permitted Exposure (MPE) limit monitoring and three-dimensional object reconstruction.
