Abstract: A first device may generate optical signals of different polarizations. Photodiodes may use the optical signals to transmit wireless signals at different polarizations and at a frequency greater than 100 GHz using the optical signals. A second device may receive the wireless signals and may convert the wireless signals into optical signals. A Stokes vector receiver on the second device may generate Stokes vectors based on the optical signals. Control circuitry on the second device may use the Stokes vectors generated for a series of training data in the wireless signals to generate a rotation matrix that characterizes polarization rotation between the first and second devices. The control circuitry may multiply wireless data in subsequently received wireless signals by the rotation matrix to mitigate the polarization rotation and other transmission impairments while using minimal resources.

Abstract: The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.

The processing circuitry is to determine a set of candidate resources of the UE from a sidelink resource pool, the sidelink resource divided into multiple time slots, frequency channels, and frequency sub-channels. Sidelink control information (SCI) is encoded for transmission to a second UE via a physical sidelink control channel (PSCCH). The SCI indicates a plurality of transmission resources of the set of candidate resources. A transport block is mapped across the plurality of transmission resources. A physical sidelink shared channel (PSSCH) is encoded for transmission to the second UE using the plurality of transmission resources, the PSSCH encoded to include the mapped transport block.

Abstract: Various implementations disclosed herein include devices, systems, and methods that provide authority transfer of a virtual object in a shared CGR environment. In some implementations, at a first electronic device associated with a first owner having authority to transmit state updates of a virtual object, a state update is transmitted to one or more peers participating in the shared CGR environment associated with the current state of the virtual object by the first electronic device. In some implementations, a handoff message is transmitted to indicate that ownership of the virtual object is being handed off. Then, an acquisition message transmitted by a second electronic device associated with a second owner indicates ownership acquisition of the virtual object by the second owner. The first electronic device accepts state updates of the virtual object transmitted from the second owner based on receiving the acquisition message.

Abstract: In some implementations a neural network is trained to perform a main task using a clustering constraint, for example, using both a main task training loss and a clustering training loss. Training inputs are inputted into a main task neural network to produce output labels predicting locations of the parts of the objects in the training inputs. Data from pooled layers of the main task neural network is inputted into a clustering neural network. The main task neural network and the clustering neural network are trained based on a main task loss from the main task neural network and a clustering loss from the clustering neural network. The main task loss is determined by comparing differences between the output labels and the training labels. The clustering loss encourages the clustering network to learn to label the parts of the objects individually, e.g., to learn groups corresponding to the object parts.

Abstract: This application relates to embodiments for providing a content stream to a device from a content server based on a protocol that is established between the device and an account server. The account server can initiate a session with the device and provide the device with a list of channels available for a user account associated with the device. When a channel is selected at the device, conditional access information can be provided from the account server to the device, which can thereafter relay the conditional access information to the content server. The content server can use the conditional access information to verify that the device has the appropriate permission to receive streaming content. In this way, because the conditional access information originates at the account server, permission to access streaming content can be managed by correspondence between the account server and the device, rather than the content server.

Abstract: An output circuit included in an integrated circuit may employ multiple protection circuits to protect driver devices from damage during an electrostatic discharge event. One protection circuit clamps a signal port to a ground supply node upon detection of the electrostatic discharge event. Another protection circuit increases the voltage level of a control terminal to one of the driver devices during the electrostatic discharge event to reduce the voltage across the driver device and prevent damage to the device.

Abstract: A communication system may include an access point (AP), a user equipment (UE), and a communication path between the AP and the UE having a series of reconfigurable intelligent surfaces (RIS's). Each RIS may have a first beam pointing to a previous node and a second beam pointing to a next node in the communication path. Beams of routing RIS's and a beam from an end user RIS towards a last routing RIS may be set during calibration. The UE may perform beam discovery with the end user RIS. The UE and the AP may convey wireless data via reflections off each of the RIS's in the communication path. The beam of the end user RIS may be updated to track the UE device while the other the beams remain fixed. The beams may be calibrated using retroreflection and beam variation for each pair of RIS's up the communication path.

Abstract: A computer system presents first computer-generated content. While presenting the first computer-generated content, the computer system detects first movement of a first user in a physical environment, and in response: in accordance with a determination that the first movement changes a spatial relationship between the first user and a second user in the physical environment from a first spatial relationship to a second spatial relationship and that the change in spatial relationship meets first criteria, the computer system changes one or more output properties of the first computer-generated content; and in accordance with the determination that the first movement changes the spatial relationship from the first spatial relationship to the second spatial relationship and that the change in spatial relationship does not meet the first criteria, the computer system presents the first computer-generated content without changing the one or more output properties of the first computer-generated content.

Abstract: An electronic device may include wireless circuitry clocked using an electro-optical phase-locked loop (OPLL) having primary and secondary lasers. A frequency-locked loop (FLL) path and a phase-locked loop (PLL) path may couple an output of the secondary laser to its input. A photodiode may generate a photodiode signal based on the laser output. A digital-to-time converter (DTC) may generate a reference signal. The FLL path may coarsely tune the secondary laser based on the photodiode signal until the secondary laser is frequency locked. Then, the PLL path may finely tune the secondary laser based on the reference signal and the photodiode signal until the phase of the secondary laser is locked to the primary laser. The photodiode signal may be subsampled on the PLL path. This may allow the OPLL to generate optical local oscillator signals with minimal jitter and phase noise.

Abstract: In an example method, a mobile device obtains sample data generated by one or more sensors over a period of time, where the one or more sensors are worn by a user. The mobile device determines that the user has fallen based on the sample data, and determines, based on the sample data, a severity of an injury suffered by the user. The mobile device generates one or more notifications based on the determination that the user has fallen and the determined severity of the injury.
