  • Patent number: 12649451
    Abstract: A redundant safety controller configured to monitor communications between at least one controller and a by-wire control system. The at least one controller has a first hardware architecture and is configured to manage operation of the by-wire control system. The redundant safety controller has a second hardware architecture. The first hardware architecture is different from the second hardware architecture. The at least one controller is configured to implement a first instruction set architecture. The redundant safety controller is configured to implement a second instruction set architecture. The first instruction set architecture is different from the second instruction set architecture. The redundant safety controller is configured to determine whether the at least one controller has failed and assume management of the operation of the by-wire control system based on the determination.

  • Publication number: 20250082095
    Abstract: A washing apparatus for viewing an obscured surface to be cleaned via a camera includes a base tube defining a base channel and an extension tube defining an extension channel. The extension tube is removably attachable to the base tube such that the base channel and the extension channel are in fluid communication with each other. A cleaning attachment is removably attachable to either one of the base tube and the extension tube and may be shaped to allow fluid to flow from the base channel or the extension channel and toward a surface to be cleaned. A camera is attached to the extension tube and is oriented to face the cleaning attachment when the cleaning attachment is attached to the extension tube.

  • Patent number: 10625692
    Abstract: This application discloses a computing system to receive a specification of prototype wiring corresponding to a signal in a logical design of a wire harness, locate a section of a vehicle to include a portion of the wire harness corresponding to the signal in the logical design, and insert the prototype wiring into a physical design of the wire harness corresponding to the located section of the vehicle. The specification of the prototype wiring can identify a particular vehicle configuration and insert the prototype wiring into a physical design of the wire harness for the particular vehicle configuration. The computing system can receive constraints configured to control synthesis of the logical design into the physical design of the wire harness, and generate portions of the physical design of the wire harness based on the constraints, while retaining the prototype wiring that was inserted into the physical design.

  • Patent number: 9810485
    Abstract: A heat exchanger comprises a stack of mutually spaced apart plates. The plates are separated by respective spacings therebetween. Alternate spacings respectively provide a flow path for a first fluid and a second fluid. The heat exchanger further comprises a first header for inflow of the first fluid and a second header for outflow of the first fluid. The first and second headers are connected to the plate stack by flexible tubular ducting means.
