Abstract: Method to perform dynamic beamforming to reduce SNR in signals captured by head-wearable apparatus starts with microphones generating acoustic signals. Microphones are coupled to first stem of the apparatus and to second stem of the apparatus. First and second beamformers generate first and second beamformer signals, respectively. Noise suppressor attenuates noise content from the first beamformer signal and the second beamformer signal. Noise content from first beamformer signal are acoustic signals not collocated in second beamformer signal and noise content from second beamformer signal are acoustic signals not collocated in first beamformer signal. Speech enhancer generates clean signal comprising speech content from first noise-suppressed signal and second noise-suppressed signal. Speech content are acoustic signals collocated in first beamformer signal and second beamformer signal.

Abstract: Apparatuses and systems for wearable devices such as eyewear are described. According to one embodiment, the wearable device includes a frame, onboard electronics components, and an antenna disposed around an eyepiece area of the frame that is configured to hold an optical element. The antenna is configured for inductive coupling. In some embodiments, a switch coupled to the antenna allows selection between circuitry for inductive charging of a battery and near-field communication (NFC) circuitry for communicating data via the antenna.

Abstract: An eyewear device has an antenna system having at least one element which contributes to wireless signal transmission, and which is thermally connected to a heat-generating electronic component of the eyewear device to serve as a heat sink for the electronic component. A driven antenna element and/or a plurality of PCB extenders electrically connected to a PCB ground plane can thus be employed for both signal transmission and heat management.
