  • 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.

  • Patent number: 11325810
    Abstract: A method includes a first brake block of a first brake rubber, a second brake block mounted with a second brake rubber and a mounting base for mounting the first and second brake blocks. The second brake rubber is movable along a direction slanted with respect to an axis of rotation of the traction sheave. A brake block actuation member is triggered by the brake blocks to enable the first and the second brake rubbers to hold the traction sheave. A switching member is also triggered by the action of the second brake rubber, cutting off a safety circuit of the elevator. The external power is cut off, and the brake block actuation member enables contact between the second brake rubber and the traction sheave. The traction sheave further drives the second brake rubber triggering the brake block members to generate frictional braking force to stop the traction sheave.

  • Patent number: 11303397
    Abstract: Systems and methods for early termination of feedback in respect of sidelink transmissions are provided. A first UE transmits at least one sidelink (SL) transmission of a first set of SL transmissions to a second UE, the first set of SL transmissions comprising an initial SL transmission and a set number of SL retransmissions. If no ACK is received, then the first UE transmits the set number of retransmissions. On the other hand, if an ACK is received, then the first UE transmits fewer than the set number of SL retransmissions when an ACK is received from the second UE before the set number of SL retransmissions has been completed. By transmitting fewer than all of the set number of SL retransmissions, resources can be freed up for other purposes. The approach may be used for SL configured grant transmission.

  • Publication number: 20220097728
    Abstract: Systems and methods are disclosed for optimizing values of a set of tunable parameters of an autonomous driving vehicle (ADV). The controllers can be a linear quadratic regular, a “bicycle model,” a model-reference adaptive controller (MRAC) that reduces actuation latency in control subsystems such as steering, braking, and throttle, or other controller (“controllers”). An optimizer selects a set tunable parameters for the controllers. A task distribution system pairs each set of parameters with each of a plurality of simulated driving scenarios, and dispatches a task to the simulator to perform the simulation with the set of parameters. Each simulation is scored. A weighted score is generated from the simulation. The optimizer uses the weighted score as a target objective for a next iteration of the optimizer, for a fixed number of iterations. A physical real-world ADV is navigated using the optimized set of parameters for the controllers in the ADV.
