Abstract: A serial data receiver subsystem included in a computer system may include a data detection circuit, a speed detection circuit, and a receiver circuit that includes multiple subcircuits. The data detection circuit performs a comparison of a reference voltage to the magnitude of signals received via a communication link that encodes a serial data stream consisting of multiple data symbols. Using a result of the comparison, the data detection circuit may activate a signal present indicator indicating the presence of data on the communication link. Once the signal present indicator is active, the speed detection circuit checks the number of transitions to determine a rate at which data is being transmitted. In response to a determination that the rate of the data being transmitted exceeds a threshold value, the receiver circuit activates one or more of the multiple subcircuits.

Abstract: A phase detector circuit for use with a multi-level signaling communication protocol on a serial communication link is disclosed. The phase detector circuit employs multiple phase and logic circuits to detect data state changes between adjacent ones of voltage levels corresponding to different data states in the communication protocol, and generates early/late signals using the detected data state changes. The phase detector circuit statistically filters data state transitions between non-adjacent voltage levels to improve phase locking and reduce recovered clock jitter.

Abstract: A vehicle may wirelessly communicate with another vehicle via a physical channel (a vehicle-to-vehicle (V2V) channel) that is robust and reliable under high mobility propagation conditions. The physical channel may be created by modifying an existing long-term evolution (LTE) physical channel, such as an LTE sidelink (SL) channel. For instance, the V2V physical channel may be created by increasing, by a particular factor, the subcarrier spacing of legacy LTE channels (e.g., from 15 kilohertz (kHz) to 30 kHz). Additionally, a symbol duration and a fast Fourier transform (FFT) size for the V2V physical channel may each be reduced by the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.

A propulsion system is configured to cause motion current location toward the pickup location according to the trajectory.

Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: A system and method for efficiently transferring data between devices. In various embodiments, a host computing device receives parallel data, encodes the parallel data as a count of pulses as serial data, and conveys the serial data to a peripheral device. The peripheral device decodes the received serial data to determine the parallel data, which is sent to processing logic. The devices send the encoded pluses on a bidirectional line, so the pulses are capable of being sent in both directions. The devices send the encoded pulses on the bidirectional line using a non-zero base voltage level. The devices are capable of using a voltage headroom when conveying encoded pulses between one another. Therefore, a full voltage swing between a ground reference voltage level and a power supply voltage level is not used when conveying the encoded pulses, which reduces power consumption.

A plurality of accepting sections and a plurality of blocking sections can be employed to selectively allow light having an angle of incidence within one or more acceptance viewing angles and block light with angles of incidence outside of the acceptance viewing angles. In some examples, the light restriction designs can include variations in optical and structural properties can allow the light restriction designs to have spatially varying acceptance angles. Variations in structural properties can include, but are not limited to, differences in widths, heights, and/or tilts of the accepting sections and/or blocking sections.

Abstract: This disclosure relates to techniques for performing communication in a wireless communication system. The communication may be semantic communication and/or may use a programmable protocol stack. A protocol stack at a transmitter and/or receiver may include customization from an application platform, e.g., which may replace one or more layers relative to a non-customized protocol stack. A transmitter may transmit data, via the customized protocol stack, using a best effort data channel, e.g., with transmission characteristics that are relatively lossy in comparison to a data channel used by the non-customized protocol stack. A receiver may receive the data and may, e.g., if the data is corrupted, select one or more model to recover the data and/or determine whether reception is successful, e.g., from a semantic point of view. The proposed system may support higher data rates, less retransmissions, and/or better quality of user experience.

Abstract: Latency reduction techniques for radio access networks are described. In various embodiments, a reduced transmission time interval (rTTI) may be implemented in order to reduce air interface latency in a radio access network. In some embodiments, an rTTI block may be defined, and some operations may be performed in rTTI block-wise fashion in order to reduce the marginal overhead associated with implementation of the rTTI. In various embodiments in which an rTTI is implemented, DM-RS granularity may be improved by use of techniques that enable data and reference signals to be multiplexed within a same OFDM symbol. In some embodiments, a current transmission time interval (TTI) may be maintained, and latency reduction may be achieved via the use of novel techniques for one or more of code block (CB) segmentation, uplink (UL) resource element (RE) mapping, and HARQ cycle timing. Other embodiments are described and claimed.

Update circuitry, coupled to an output of the storage circuit, generates an updated local timebase using a clock signal in the second clock domain, wherein the updated local timebase is subject to the adjusted timebase limit.

Abstract: Methods to trigger eye enrollment without requiring good gaze interaction are described that allow a guest user of a device to initiate partial or full eye enrollment even though their eye model is not known and thus conventional gaze-based interactions do not work well. A gaze tracking system collects gaze data in the background. At any time (or within an interval after a user puts on the device), an eye enrollment can be triggered by detecting some gaze gesture, for example rolling the eyes in a large circle, or moving the eyes randomly for a time that exceeds a threshold. Depending on the coverage of the gaze/cornea data collected in the background, a full eye enrollment or only a visual axis enrollment may be performed in response to the gesture.
