  • Patent number: 10996723
    Abstract: A method for providing, based on an emulation schedule, a reset message to multiple circuits is provided. The reset message associates a reset signal with a selected clock cycle for each circuit, in the emulation schedule. The method includes determining a mask for each of the circuits based on the emulation schedule, providing a clock signal to the circuits, the clock signal comprising the selected clock cycle for each circuit, and tuning the reset signal relative to the clock signal based on a center of the selected clock cycle for each circuit. The method also includes providing the reset signal to the circuits and asserting the reset signal in the circuits based on the mask. A system and a non-transitory, machine-readable medium storing instructions to perform the above method are also provided.

  • Publication number: 20200189487
    Abstract: Vehicle sensor systems include modular sensor kits having one or more pods (e.g., sensor roof pods) and/or one or more bumpers (e.g., sensor bumpers). The sensor roof pods are configured to couple to a vehicle. A sensor roof pod may be positioned atop a vehicle proximate a front of the vehicle, proximate a back of the vehicle, or at any position along a top side of the vehicle being coupled, for example, using a mounting shim or a tripod. The sensor roof pods can include sensors (e.g., LIDAR sensors, cameras, ultrasonic sensors, etc.), processing units, control systems (e.g., temperature and/or environmental control systems), and communication devices (e.g., networking and/or wireless devices).

  • Patent number: 10584751
    Abstract: A load reduction assembly includes an annular bearing cone configured to extend between a bearing assembly and a frame assembly and form a first load path therebetween. The load reduction assembly further includes an annular recoupler member configured to extend between the bearing assembly and the frame assembly and form a second load path therebetween. The second load path is parallel to the first load path. The recoupler member includes a shape memory alloy configured to change stiffness in response to a change in a stress condition, thereby regulating an imbalance condition of a rotor shaft coupled to the bearing assembly.

  • Publication number: 20190178104
    Abstract: A gas turbine engine includes a compressor section and a turbine section arranged in serial flow order. A shaft is provided rotatable with at least a portion of the compressor section and with at least a portion of the turbine section. A bearing is also provided supporting rotation of the shaft, with a support element in turn supporting the bearing. The gas turbine engine also includes a superelastic member formed of a shape memory alloy supporting at least one of the support element or the bearing. The superelastic member is installed in a pre-stressed condition to enhance a dampening function of the superelastic member.

  • Patent number: 10196934
    Abstract: A rotor support system for a gas turbine engine may generally include a bearing assembly and a load reduction member configured to be coupled between the bearing assembly and a support frame of the engine. The load reduction member may include a fuse portion configured to fail when a load transmitted through the load reduction member exceeds a predetermined load threshold. The system may also include a load recoupling member provided between the bearing assembly and the support frame. The load recoupling member may be formed from a super-elastic shape memory alloy that allows the load recoupling member to undergo recoverable deformation without failing when the fuse portion fails such that the load recoupling member maintains a mechanical connection between the bearing assembly and the support frame.
