A tracking device monitors a portion of a user's skin to infer a pose or gesture made by a body part of a user that engages the portion of the user's skin as the pose or gesture is made. For example, the tracking device monitors a portion of skin on a user's forearm to infer a pose or gesture made by the user's hand. The tracking device may include an illumination source that illuminates the portion of the user's skin. An optical sensor of the tracking device may capture images of the illuminated portion of skin. A controller of the tracking device infers a pose or gesture of the body part based in part on a model (e.g., a machine-learned model) and the captured images. The model may map various configurations of the user's skin to different poses or gestures of the body part.

Inferring user pose using optical data

Apparatuses, methods, and systems for a site survey tool are disclosed. One site survey tool includes an elevated platform comprising a directionally adjustable beam-forming antenna, and operates to adjust an elevation (z coordinate) of the adjustable beam-forming antenna, a ground unit that operates to adjust to a plurality of locations (x and y coordinates). The elevated platform and the ground unit operate to determine an angular spread boundary of a supercell base station, determine a power azimuth angular spectrum threshold needed in order for the supercell base station to support adaptive sectorization, estimate a power azimuth angular spectrum of a site, and determine that the site supports the supercell base station if the estimated power azimuth angular spectrum of the site is less than the power azimuth angular spectrum threshold at the angular spread boundary.

Determining whether a site supports a supercell base station

Apparatuses, methods, and systems for a site survey tool are disclosed. One site survey tool includes an elevated platform, wherein the elevated platform includes a directionally adjustable beam-forming antenna, wherein the elevated platform operates to adjust an elevation of the adjustable beam-forming antenna, and wherein the elevated platform operates to transmit or receive wireless signals while the directionally adjustable beam-forming antenna changes a beam direction. Further, a ground unit transmits wireless signals to the elevated platform or receives wireless signals from the elevated platform while the directionally adjustable beam-forming antenna changes the beam direction. A signal quality of received wireless signals is measured, and a power azimuth angular spectrum of a surveyed site is estimated based on a known motion of the adjustable beam-forming antenna, a known beam-forming pattern of the adjustable beam-forming antenna, and the measured phase and amplitude of the received wireless signals.
