  • Patent number: 11680616
    Abstract: Some embodiments relate to an electro-mechanical actuator that includes a screw, structurally segregated (split) housings, first and second nuts coupled to the screw, a sensor assembly, a plurality of motors, and a controller. The first nut is coupled to a first mounting point, and the second nut is coupled to a second mounting point. The sensor assembly may generate signals indicative of (e.g., relative) positions of left and right units of the actuator or positions of the first nut and the second nut on the screw. The controller controls the motors based on the signals generated by the sensor assembly. The motors may rotate each nut about a screw axis of the screw. This rotation results in one or both nuts moving along the screw. Movement between the first nut and the second nut along the screw adjusts a distance between the first mounting point and the second mounting point.

  • Publication number: 20230185752
    Abstract: A Universal Serial Bus (USB) cable includes a connector and a switch. The connector includes a housing configured for gripping by a user to manually insert/remove the connector to/from a port of an electronic device. The connector includes a power line configured to enable transfer of power to the electronic device and a data line configured to enable exchange of data with the electronic device. The switch is integrated into the outer surface of the housing and includes, for example, a toggle that is mechanically movable between a first position that activates a private mode and a second position that deactivates the private mode. The exchange of data with the electronic device is only enabled while the toggle is in the second position, and the transfer of power to the electronic device is enabled regardless of whether the toggle is in the first position or the second position.

  • Publication number: 20230166770
    Abstract: Four-wheel steering of a vehicle, e.g., in which leading wheels and trailing wheels are steered independently of each other, can provide improved maneuverability and stability. A first vehicle model may be used to determine trajectories for execution by a vehicle equipped with four-wheel steering. A second vehicle model may be used to control the vehicle relative to the determined trajectories. For instance, the second vehicle model can determine leading wheels steering angles for steering leading wheels of the vehicle and trailing wheels steering angles for steering trailing wheels of the vehicle, independently of the leading wheels.

  • Patent number: 11616786
    Abstract: Various computers will communicate messages back and forth over a communication network. These communications may exchange various information. In one aspect, an apparatus for communicating data over a communication network may comprise a computer processor, a receiver, and a memory. The computer processor may generate a request for transmission to a first server via the communication network. The request may include a data inquiry for data about an authorized user of a communication device. The computer processor may also generate a communication message for transmission to the authorized user with a prompt to provide user data via the communication device. The receiver may receive a response from the first server and user data from the communication device. The computer processor may further format the user data and generate a dynamic value based on the formatted response for display.

  • Publication number: 20230023286
    Abstract: A watercraft comprises a vehicle payload bay; a sail connected to the payload bay for propelling the watercraft in a foiling mode; and three or more hydrofoils connected to the payload bay. The hydrofoils are configured to provide control of the roll, pitch, and yaw of the watercraft and to elevate the vehicle payload by above a water surface when the watercraft is in the foiling mode. The hydrofoils can also provide control of roll, pitch, yaw, and elevation of the watercraft during the transition from a prone mode to a foiling mode. A mechanical propulsive system can be used for propelling the watercraft at least during transition from the prone mode to the foiling mode. The watercraft may not include a hull such that during the transition from the prone mode to the foiling mode, pitch and roll control are not substantially provided through the actions of gravity and buoyancy.
