摘要： Implementations disclosed describe techniques and systems for efficient determination and tracking of trajectories of objects in an environment of a wireless device. The disclosed techniques include, among other things, obtaining multiple sets of sensing values that characterize one or more radio signals received, during a respective sensing event, from an object in an environment of the wireless device. The sensing signals may be carried by waves with randomly selected frequencies representing a portion of all frequencies that are used as working sensing frequencies. Multiple techniques of efficient frequency interpolation and temporal interpolation are disclosed that reconstruct the sensing values to the full range of working frequencies. The reconstructed sensing values may then be used to track objects in the environment.

摘要： A mode-transition architecture for USB controllers is described herein. In an example embodiment, an integrated circuit (IC) controller includes a controller coupled to a slope compensation circuit, the controller to detect a transition of a buck-boost converter from a first mode having a first duty cycle to a second mode having a second duty cycle that is less or more than the first duty cycle. The controller controls the slope compensation circuit to nullify an error in an output caused by the transition. The controller can cause the slope compensation circuit to apply a charge stored in a capacitor during a first cycle to start a second cycle with a higher voltage than the first cycle.

摘要： Implementations disclosed describe techniques to effectuate operating mode changes of a wireless connection between a first communication device (CD) and a second CD. In an example embodiment, the disclosed techniques may include detecting, by a wireless network controller of the second CD, an indication that the first CD has requested the operating mode change from a first operating mode to a second operating mode. The disclosed techniques may further include modifying a transmission information (TI) associated with one or more frames in a transmission queue of the second CD, the TI including a representation used by a physical layer of the second CD to configure transmission of a respective frame to the first CD, wherein the one or more frames in the transmission queue have been previously programmed with a first-mode TI, and wherein modification of the TI is to a second-mode TI.

摘要： A method can include receiving user input values via a plurality of inputs of a motor vehicle and determining if each received user input value corresponds to an authenticated user value in a secure memory of the motor vehicle. For each received user input value corresponding to an authenticated user value, a certainty factor corresponding to the authenticated user value can be accessed from a secure memory. A certainty score can be generated from all accessed certainty factors. Each of a plurality of permissions for operating or accessing the motor vehicle can be enabled in response to a comparison between the certainty score and a certainty threshold assigned to each permission. Corresponding devices and systems are also disclosed.
