Abstract: Disclosed herein includes a system, a method, and a device for managing energy detection thresholds. A device can perform an energy detection (ED) measurement of a channel, comparing against a defined ED threshold function, so as to determine if the channel is occupied. The device can perform a measurement of a channel indicative of a power level of signals detected in the channel. The device can compare the measurement to a threshold having a value that is a continuous monotonic function having a sloped region between a first region having a first constant value and a second region having a second constant value. The sloped region can include a function of a maximum transmit power of the device and at least one of the first constant value or the second constant value. The device can determine, responsive to the comparison, whether the channel is occupied or unoccupied.

Abstract: An electronic system is described that is responsive to non-verbal commands.

The speaker system may be equipped with a bone conduction sensor or in-ear microphone that generates data associated with vibrations of a facial region of the user.

The system may perform various predetermined operations based on the detected vibrations.

Abstract: Described are techniques for generating a supply voltage for an SRAM array using power switching logic. The power switching logic can generate the supply voltage using a first supply rail (supplying a higher voltage) during an active state and using a second supply rail (supplying a lower voltage) during a deep retention state. In some examples, a sensing and recovery (SR) unit is provided to sense a decrease in the second voltage, for instance, during the deep retention state. The SR unit can generate an additional voltage that modifies the supply voltage to be higher than the decreased second voltage, thereby reducing droop and/or noise in the second supply rail. The power switching logic, SR unit, and SRAM array can be co-located or distributed across a computer system. For instance, the power switching logic, SR unit, and SRAM array can be embedded within a System on Chip integrated circuit.

Abstract: The present embodiments relate to automated memory creation and retrieval from moment content items. In some implementations, the automated memory creation and retrieval system can obtain moment content items from user-designated sources with a single user perspective or multiple user perspectives. The moment content items can be assigned tags and arranged in chronological order. The arranged moment content items can be clustered into memory content items based on clustering conditions. Once memory content items are created, they can be arranged into a memory hierarchy made up of connected nodes. In some implementations, the memory content items are also linked together based on similarity in various dimensions in a memory graph. The automated memory creation and retrieval system can receive search criteria for memories from a user interface and provide the user with memories from matched nodes in the memory hierarchy or linked memories in the memory graph.

Abstract: A near eye display (NED) includes multiple PBP optical elements combined with one or more C-plates to improve optical angular performance. The PBP optical elements may be configured for beam steering or for focusing light to a point. A C-plate may reduce or eliminate an undesirable polarization phase shift introduced by the PBP optical elements to angular, off-axis light. Birefringence of the PBP optical elements produces such a polarization phase shift. A C-plate provides an additional polarization phase shift that is opposite to the extra polarization phase shift by the PBP optical elements. Thus, the additional polarization phase shift by the C-plate at least partially reduces the phase shift by the PBP element.
