  • Publication number: 20240315459
    Abstract: A bed system can have an adjustable foundation and a user interface having at least one adjustment bar. The user interface can be communicatively coupled to an actuation system of the adjustable foundation such that raising a foot portion of the at least one adjustment bar can signal the actuation system to raise a foot section of the adjustable foundation, raising a head portion of the adjustment bar can signal the actuation system to raise a head section of the adjustable foundation, lowering the foot portion of the adjustment bar can signal the actuation system to lower the foot section of the adjustable foundation, and lowering the head portion of the adjustment bar can signal the actuation system to lower the head section of the adjustable foundation.

  • Publication number: 20240208475
    Abstract: Example embodiments relate to triple redundant brake systems for trucks and other types of vehicles. Disclosed systems offer additional redundancy for braking applications by incorporating a third service brake actuator (e.g., a third ECU), which may be installed parallel to the second controller (e.g., a second ECU). In some examples, the third service brake actuator is an electronically activatable pressure valve and can be implemented using pneumatic select-high valves. These valves can be used to perform a mechanical max arbitration between pressure provided by the second controller and the third controller.

  • Patent number: 11427175
    Abstract: Techniques for braking an autonomous vehicle include providing a pressurized fluid stream from a plurality of pressurized fluid sources to a plurality of pressure-controlled electronic braking assemblies; providing the pressurized fluid stream from a pressurized fluid control output of a first pressure-controlled electronic braking assembly directly to a pressurized fluid control input of a second pressure-controlled electronic braking assembly; providing the pressurized fluid stream from the second pressure-controlled electronic braking assembly to at least one vehicle brake set; providing sensor output data from one or more vehicle sensors to a plurality of electronic control units; and based at least in part on the sensor output data, controlling at least one of the first or second pressure-controlled electronic braking assemblies to adjust a pressure of the pressurized fluid stream from at least one of the first or second pressure-controlled electronic braking assemblies to the vehicle brake set.

  • Patent number: 8640926
    Abstract: A fluid dispenser including a backplate and a flexible cover fixedly secured to the backplate. A refill unit including a product reservoir and a pump is positioned within the dispenser and is carried by the backplate. The flexible cover is adapted to flex or deform when pressed by a user to actuate the pump, thereby alleviating the need for separate actuating members or pivoting of the cover.
