  • Patent number: 10259434
    Abstract: Braking system includes a brake, first valve that actuates the brake based on user input, second valve configured to selectively actuate the brake, and valve actuation system including a user input device moveable between first and second positions. A brake sensor provides a signal indicative of actuation of the first valve. The valve actuation system activates the second valve if the user input device is in the first position and the first valve engaged, retaining the second valve in active state if the first valve is disengaged, deactivating the second valve if the user input device is in the second position.

  • Patent number: 10003405
    Abstract: A Data Over Cable Service Interface Specifications (DOCSIS) Passive Optical Network (PON) system (DPON) makes optical subscribers appear as cable subscribers. In one embodiment, a Cable Modern (CM) proxy is located in an Optical Line Termination (OLT). The OLT implements a cable modem protocol stack that operates as the CM proxy and communicates with a back office system. The OLT translates the data retrieved by the CM proxy into Optical Network Unit (ONU) recognizable commands, and sends the translated data to the ONU. In a second embodiment, the CM proxy is located in the ONU. The ONU implements the cable modern protocol stack that operates as the CM proxy and communicates with the back office system. The ONU translates the data retrieved by the CM proxy into ONU recognizable commands and sends the translated data to the ONU.

  • Patent number: 9625036
    Abstract: The present disclosure relates to a vehicle having a braking system and a method of engaging the braking system. The braking system engages a brake mechanism as a waiting brake. The vehicle has a dual function device which is configured such that when the dual function device is activated when the vehicle transmission system is in a drive mode, the transmission system is maintained in that drive mode, and when the dual function device is activated when the transmission system is in the neutral mode, the brake mechanism is engaged.

  • Patent number: 9112816
    Abstract: In one example, an Edge Quadrature Amplitude Modulation (EQAM) communicates EQAM information to a Modular Cable Modem Termination System (M-CMTS) core using a routing protocol that is configured on a packet switched network coupling the EQAM to the M-CMTS core. The EQAM generates a routing message according to the routing protocol and inserts EQAM information, such as a description of a modulated channel extending from the EQAM, the service-group information, etc., into the routing message. The EQAM then floods the EQAM information over at least portions of a routing domain by transmitting the routing message to an adjacent intermediary device.
