Inventor(s): Joshua Cobb of Victor NY (US) for meta platforms technologies, llc, Derek Wallin of Monroe WA (US) for meta platforms technologies, llc, Ajit Ninan of San Jose CA (US) for meta platforms technologies, llc, Chun Chi Wan of San Jose CA (US) for meta platforms technologies, llc
IPC Code(s): F21V9/14, F21Y115/10, G02B27/01, H01L33/50, H01L33/60, H04N9/31
CPC Code(s): G02B27/0172
Abstract: a polarizing illuminator includes a light source, a collimator for collimating a light beam emitted by the light source, a parallel plate having a first surface and a second surface disposed at an acute angle with respect to the light beam, the first surface including a transmissive portion and a reflective portion, and the second surface including a reflective polarizer configured to reflect one polarization of the light beam, transmit an orthogonal polarization of the light beam, and split the light beam into first and second orthogonally polarized sub-beams, and a retarding wave plate disposed between the reflective portion of the first surface and the reflective polarizer, wherein the retarding wave plate is configured to rotate at least one of the first sub-beam and the second sub-beam to a matched polarization, and the first and second sub-beams having the matched polarization propagate parallel to each other.

IPC Code(s): G02B27/01, G01D5/24
CPC Code(s): G02B27/0179
Abstract: a head-mounted device may include a frame, a display coupled to the frame, a front head-engaging structure coupled to the frame, a retention mechanism configured to secure the front head-engaging structure to the head of the user, and one or more non-contact sensor(s) disposed on one or more of the frame, the display, the retention mechanism, and/or the front head-engaging structure. the non-contact sensor(s) may be configured to detect a measurement of the head of the user. in some examples, the measurement may include a head circumference, a size and/or shape of the head. in some examples, the head-mounted device may dynamically adjust a length of the retention mechanism based in part on the sensor data received from the one or more non-contact sensor(s).

IPC Code(s): H04W52/02, H04W72/23
CPC Code(s): H04W52/0216
Abstract: systems, methods, and devices for indicating a target wake time (twt) service period (sp) termination may include a first device which receives, from a second device, an indication for terminating a twt sp. the first device may determine a status of downlink traffic for transmission to the second device. the first device may transmit, to the second device, an sp termination notification according to the status of the downlink traffic and the indication. the first device may terminate the twt sp according to the sp termination notification.
