Abstract: A method for adjusting transmitter output power (PTX) comprises sensing, by a proximity sensor communicatively coupled to a transmitting device, whether an object is proximate to the transmitting device. The method further comprises analyzing an image from a camera to determine whether the transmitting device is proximate to a portion of a human body, when the proximity sensor senses the object proximate to the transmitting device. Further, the method comprises adjusting the PTX of an antenna operatively coupled to the transmitting device to be less than or equal to a SAR threshold output power (PSARMAX), when it is determined that the transmitting device is proximate to the portion of the human body or when it cannot be determined whether the transmitting device is proximate to a portion of a human body.

Abstract: Techniques for operating a depth sensor are discussed. A first sequence of operation steps and a second sequence of operation steps can be stored in memory on the depth sensor to define, respectively, a first depth sensing mode of operation and a second depth sensing mode of operation. In response to a first request for depth measurement(s) according to the first depth sensing mode of operation, the depth sensor can operate in the first mode of operation by executing the first sequence of operation steps. In response to a second request for depth measurement(s) according to the second depth sensing mode of operation, and without performing an additional configuration operation, the depth sensor can operate in the second mode of operation by executing the second sequence of operation steps.

Abstract: A method of using a first device to locate a second device is disclosed. The first device, while in a first mode, transmits a first signal and receives a second signal comprising a reflection of the first signal by the second device. The first device determines, based on the received second signal, a position of the second device relative to the first device. The first device transitions to a second mode, and while in the second mode, receives a third signal from the second device. The first device determines, based on the third signal, an orientation of the second device relative to the first device. The first device comprises one or more receiving antennas, and the second device comprises one or more transmitting antennas. The third signal corresponds to a transmitting antenna of the second device.

Abstract: A system and method for operating a depth sensor. A configuration operation can be performed by storing a first sequence of operation steps which define a first depth sensing mode of operation, and a second sequence of operation steps which define a second depth sensing mode of operation, in the memory. In response to a first request for depth measurements according to the first depth sensing mode of operation, the depth sensor can be operated in the first mode of operation by causing it to execute the first sequence of operation steps. In response to a second request for depth measurements according to the second depth sensing mode of operation, and without performing an additional configuration operation, the depth sensor can be operated in the second mode of operation by causing it to execute the second sequence of operation steps.

Abstract: An augmented reality device has a radar system that generates radar maps of locations of real world objects. An inertial measurement unit detects measurement values such as acceleration, gravitational force and inclination ranges. The values from the measurement unit drift over time. The radar maps are processed to determine fingerprints and the fingerprints are combined with the values from the measurement unit to store a pose estimate. Pose estimates at different times are compared to determine drift of the measurement unit. A measurement unit filter is adjusted to correct for the drift.
