  • Patent number: 11549565
    Abstract: A method for controlling vehicle motion is described. The method includes: comparing a measured acceleration value associated with a movement of a vehicle component of a vehicle with a predetermined acceleration threshold value that corresponds to the vehicle component, wherein the vehicle component is coupled with a frame of the vehicle via at least one vehicle suspension damper; monitoring a state of at least one valve within at least one vehicle suspension damper of the vehicle, wherein the state controls a damping force within the at least one vehicle suspension damper; and based on the comparing and the monitoring, regulating damping forces within the at least one vehicle suspension damper by actuating the at least one valve to adjust to a desired state, such that an acceleration of the frame is reduced.

  • Publication number: 20130087210
    Abstract: The present invention relates to a device and method for conveying fluids into the treatment unit of a medical treatment apparatus. The device and method according to the present invention are based on the fact that the fluid with which the treatment unit is supplied, circulates in a fluid circuit including the treatment unit. To balance fresh and used fluid fed to the treatment unit or conveyed from the treatment unit, a balancing unit with a balancing chamber is used, which can be incorporated into the fluid circuit including the treatment unit. It is thus possible to supply the fluid circuit continuously with fresh fluid or to carry away used fluid continuously from the fluid circuit. The supply and discharge of fresh and used fluid can take place at a different flow rate from the flow rate at which the fluid circulates in the fluid circuit via the treatment unit.

  • Patent number: 8181665
    Abstract: A flushing unit for flushing vapor compressions systems with a flushing agent. The flushing unit includes a pressure relief member to ensure that the reservoir containing the flushing agent is not over-pressurized. In certain embodiments, the flushing unit is adapted to be in communication with a driving fluid or propellant, such as an inert gas or a flushing gas, and with a source of a flushing agent, such as a reservoir. The flushing unit includes a valve that, when opened, causes the driving fluid to flow into the reservoir containing the flushing agent and displace the flushing agent from the reservoir, causing it to ultimately flow into the system being flushed such as via a suitable hand-held injector. In the event the pressure in the reservoir exceeds a predetermined level, a pressure relief valve in the flushing unit is automatically actuated, thereby relieving pressure in the otherwise closed system.
