  • Patent number: 11768076
    Abstract: Aspects of the disclosed invention relate to alignment of standard definition (SD) maps and high definition (HD maps) which may come from different sources. Responsive to input of a destination, a route to that destination may be defined, and SD map waypoints generated from that defined route. A graph may be generated from the HD map. The waypoints may be matched with nodes and edges in the graph. One or more edges may constitute a segment in the HD map. A plurality of segments are identified to match the route.

  • Publication number: 20230245413
    Abstract: Some embodiments provide a mapping application that displays a rotation of a 3D map and corresponding rotation of a set of map labels overlaying the 3D map in response to receiving input to rotate the 3D map. When a particular map label in the set of map labels rotates towards an upside down orientation, the mapping application also replaces the particular map label with a version of the particular map label arranged in a right side up orientation to prevent the particular map label from being displayed in the upside down orientation in the 3D map.

  • Publication number: 20230173435
    Abstract: Embodiments described herein relate generally to durable graphene oxide membranes for fluid filtration. For example, the graphene oxide membranes can be durable under high temperatures non-neutral pH, and/or high pressures. One aspect of the present disclosure relates to a filtration apparatus comprising: a support substrate, and a graphene oxide membrane disposed on the support substrate. The graphene oxide membrane has a first lactose rejection rate of at least 50% with a first 1 wt % lactose solution at room temperature. The graphene oxide membrane has a second lactose rejection rate of at least 50% with a second 1 wt % lactose solution at room temperature after the graphene oxide membrane is contacted with a solution that is at least 80° C. for a period of time.

  • Publication number: 20220313114
    Abstract: A valve housing for use in an apparatus for measuring inspiratory and expiratory lung pressure, the valve housing comprising a first body portion which defines a mouthpiece; a second body portion coupled to the first body portion and which defines a port; a filter medium disposed between the first and second body portions; a pair of spaced apart valve support bodies defined by one of the first and second body portions, wherein each valve support body defines an air flow conduit that includes a support frame disposed within the conduit, the support frame having a first side and a second side; and a pair of valves, wherein the valves are selectively secured to the respective first sides of the support frame or are secured to the respective second sides of the support frame, wherein when the valves are secured to the first sides of the support frame, they open to permit air to exit the valve housing via the air flow conduits, but close to prevent air being drawn into the valve housing from the external environme

  • Publication number: 20220017060
    Abstract: Monitoring the brake performance of a brake system of a machine (vehicle 11) by determining a brake delay between input of a request for a brake engagement of the brake system and brake system effectuating the brake engagement. The brake delay determination provides for capturing delay produced by communication of the input from a brake input, actuation of an input to brake system performance, processing of operation of the brake system, and operation of the brake/retardation components of the brake system with respect to the machine's wheels. For autonomous machines, brake delay may be measured periodically and used in monitoring brake system performance.

  • Publication number: 20220009469
    Abstract: A control system is used to monitor the brake performance of a machine by detecting a brake engagement for decelerating the machine. If a wheel lock of at least one wheel of the machine is detected during the brake engagement and resulting from the brake engagement whilst the machine is moving, the data collected by the control system for brake engagement is rejected or the generation of brake performance data associated with the brake engagement is prevented. The machine may be an autonomous machine and the brake engagement may be routinely scheduled to provide for brake system monitoring while the machine is in operation.

  • Publication number: 20210402972
    Abstract: Monitoring the brake performance of a brake system of a machine and a control systems for performing such monitoring. The machine's brake system is monitored by detecting a brake engagement for decelerating the machine. When a brake engagement is detected, a parasitic loss decelerating the machine during the brake engagement is determined. The parasitic loss is used to predict deceleration of the machine during the brake engagement Brake performance of the brake system of the machine is processed from the predicted deceleration.
