  • Patent number: 11931220
    Abstract: Wax-based compositions for making barrier layers used in oral treatment devices are thermally stable when formed into a flat sheet or three-dimensional article to a temperature of at least 45° C. and are plastically deformable at room temperature (25° C.). The wax-based compositions include a wax fraction homogeneously blended with a polymer fraction. The wax fraction includes at least one wax and the polymer fraction includes at least one polymer selected such that, when the at least one wax and at least one polymer are homogeneously blended together, they yield a wax-based composition having the desired properties of thermal stability and plastic deformability. Barrier layers and oral treatment devices made from such wax-based compositions are dimensionally stable to a temperature of at least 40° C. without external support and can be plastically deformed in a user's mouth to become at least partially customized to the size and shape of user's unique dentition.

  • Patent number: 11787255
    Abstract: A machine includes a first cylinder coupled to a first wheel and a second cylinder coupled to a second wheel. A first proportional dampening valve fluidly connects to the first cylinder and a second proportional dampening valve fluidly connects to the second cylinder. First accumulators are fluidly connected to the first cylinder and the first proportional dampening valve, and second accumulator(s) are fluidly connected to the second cylinder and the second proportional dampening valve. Additionally, a first proportional flow control valve fluidly connects to the first cylinder and a second proportional flow control valve fluidly connected to the second cylinder. An electronic control module (ECM) communicatively couples to the first proportional flow control valve and the second proportional flow control valve to adjust a ride height of the first wheel via the first cylinder and a ride height of the second wheel via the second cylinder.

  • Patent number: 11283692
    Abstract: Service discovery for an application lacking capabilities sufficient to facilitate Universal Plug and Play (UPnP), Zero-configuration networking (Zeroconf), Simple Service Discovery Protocol (SSDP) or other service discovery protocols relying upon multicast User Datagram Protocol (UDP) is contemplated. The service discovery may be facilitated with a discovery proxy configured to identify available services and a discovery service having capabilities sufficient to apprise the application of the services identified with the discovery proxy.

  • Patent number: 9555784
    Abstract: A braking system for a machine includes a first valve assembly having a first electronically actuated proportional valve, and a second valve assembly having a second electronically actuated proportional valve. The braking system includes a first pressure sensor and a second pressure sensor disposed downstream of the first and second valve assemblies, respectively. The first and second pressure sensors are configured to determine a first pressure and a second pressure of a braking fluid from the first and second valve assembly. The braking system also includes a controller configured to receive a signal indicative of the first pressure and the second pressure of the braking fluid and compare the first pressure and the second pressure. The controller is configured to selectively actuate at least one of the first electronically actuated proportional valve and the second electronically actuated proportional valve to substantially equalize the first pressure and the second pressure.
