  • Patent number: 8850782
    Abstract: The invention relates to safety improvements for mowers incorporating a chipper, and/or catcher. In one aspect the invention provides safety improvements that only allow operation of the chipper when the mower is below a predetermined threshold ride height. In another aspect, the mower includes one or more side skirts to prevent body parts from entering the cutting zone under the mower. In a still further aspect, the mower has a rear flap including a sub-flap. The mower is arranged so that the sub flap remains closed when a catcher is installed.

  • Patent number: 8825239
    Abstract: A method for communicating data in a rail vehicle consist includes transmitting first data at a first rail vehicle of the consist over a power supply conductor to a second, different rail vehicle in the consist, where at least one rail vehicle of the consist receives direct electrical power from the power supply conductor. The method also includes monitoring the power supply conductor for second data at the first rail vehicle and receiving the second data over the power supply conductor at the first rail vehicle for use by a first system onboard the first rail vehicle. In one aspect, the transmitting step comprises transmitting the first data over one or more of a catenary line or a third rail that supplies the electrical power.

  • Patent number: 8538608
    Abstract: A control system for a rail vehicle system including a lead powered unit and a remote powered unit is provided. The system includes a user interface, a master isolation module and a slave controller. The user interface is disposed in the lead powered unit and is configured to receive an isolation command to turn on or off the remote powered unit. The master isolation module is configured to receive the isolation command from the user interface and to communicate an instruction based on the isolation command. The slave controller is configured to receive the instruction from the master isolation module. The slave controller causes the remote powered unit to supply tractive force to propel the rail vehicle system when the instruction directs the slave controller to turn on the remote powered unit. The slave controller causes the remote powered unit to withhold the tractive force when the instruction directs the slave controller to turn off the remote powered unit.

  • Publication number: 20070232228
    Abstract: A wireless repeater that includes a universal server base unit and modular donor antenna options. The universal server base unit includes a base unit bidirectional amplifier, a server antenna, and a housing that accepts an internal donor antenna board or an internal adapter module connected to a cable port for receiving a coaxial cable connected to an external donor antenna. This allows the same universal server base unit to work with a variety of internal and external donor antenna options. In particular, the external donor antennas include outdoor swivel-mounted options including a helical circular polarization antenna, a dual polarization panel antenna, and a vertical polarization panel antenna. The donor antenna may include an optional donor bidirectional antenna located in or near the donor antenna and powered via the cable from the server base unit.
