  • Patent number: 11425723
    Abstract: With sidelink reservation signals sent together with the sidelink data, there is the possibility of interference with other sidelink signals. In order to address this, systems and methods are provided in which a first UE transmits a reservation signal to indicate at least one time-frequency resource for transmitting sidelink data. Following this, the first UE transmits at least one sidelink data transmission to a second UE using the at least one time-frequency resource indicated by the reservation signal. The reservation signal is transmitted before the at least one sidelink data transmission signal so that a third UE may detect the reservation signal and use the reservation signal to avoid using the at least one time-frequency resource indicated in the reservation signal.

  • Publication number: 20220248451
    Abstract: Methods and systems are provided in which a UE transmits sidelink (SL) control information comprising a scheduling assignment (SA) indicating an SL transmission resource for a SL data transmission to a target UE. The SL transmission resource is based on one or more occupied SL resources identified by the UE and the SL transmission resource includes resources for an initial transmission and one or more retransmissions. The UE then transmits the SL data transmission using the SL transmission resource according to the transmitted SL control information. This is done without receiving, in a downlink control information (DCI), a grant of communication resources.

  • Publication number: 20220227397
    Abstract: Disclosed are performance metrics for evaluating the accuracy of a dynamic model in predicting the trajectory of ADV when simulating the behavior of the ADV under the control commands. The performance metrics may indicate the degree of similarity between the predicted trajectory of the dynamic model and the actual trajectory of the vehicle when applied with identical control commands. The performance metrics measure deviations of the predicted trajectory of the dynamic model from the actual trajectory based on the ground truths. The performance metrics may include cumulative or mean absolute trajectory error, end-pose difference (ED), two-sigma defect rate (?2?), the Hausdirff Distance (HAU), the longest common sub-sequence error (LCSS), or dynamic time warping (DTW). The two-sigma defect rate represents the ratio of the number of points with true location error falling out of the 2? range of the predicted location error over the total number of points in the trajectory.

  • Publication number: 20220203318
    Abstract: A submerged propylene hydration micro-interface strengthening reaction system and a method are proposed. The system includes a reactor, a first micro-interface generator and a second micro-interface generator. Through the micro-interface generators, the propylene is broken to form micron-scale bubbles, which are mixed with reactants and deionized water to form a gas-liquid emulsion, so as to increase a phase boundary area between gas and liquid phases, and achieve a strengthening mass transfer effect under a lower preset operating condition. The micro-scale bubbles can be fully mixed with the deionized water to from a gas-liquid emulsion. By fully mixing gas and liquid phases, it can ensure that the deionized water in the system is in full contact with propylene, and they are fully in contact with the catalyst, which effectively improves the efficiency of preparing isopropanol.

  • Patent number: 11361965
    Abstract: Methods of in situ fabrication and formation of horizontal nanowires for a semiconductor device employ non-catalytic selective area epitaxial growth to selectively grow a semiconductor material in a selective area opening of predefined asymmetrical geometry. The selective area opening is defined in a dielectric layer to expose a semiconductor layer underlying the dielectric layer. The non-catalytic selective area epitaxial growth is performed at a growth temperature sufficient to also in situ form a linear stress crack of nanoscale width that is nucleated from a location in a vicinity of the selective area opening and that propagates in a uniform direction along a crystal plane of the semiconductor layer in both the semiconductor layer and the dielectric layer as a linear nanogap template. The semiconductor material is further selectively grown to fill the linear nanogap template to in situ form the nanowire that is uniformly linear.
