  • Patent number: 11359745
    Abstract: A CNG leak detection system has a plurality of CNG tanks. A plurality of control valve mechanisms, equal in number to the plurality of CNG tanks, is coupled with each CNG tank. A sensor is coupled with each control valve mechanism. The sensor monitors the CNG in the tank. A processor is electrically coupled with the sensor. A display is coupled with the processor to display the sensed condition of at least one desired tank of the plurality of tanks.
    Type: Grant

  • Patent number: 10351341
    Abstract: A control mechanism for a refuse vehicle includes a first control valve that operates a first hydraulically controlled mechanism and a second control valve that operates a second hydraulically controlled mechanism. The control mechanism also includes a plurality of switches and a pneumatic control mechanism. The plurality of switches generates a valve select signal and a mode signal. The pneumatic control mechanism selectively controls the first control valve and the second control valve based on the valve select signal and the mode signal. An operator of the refuse vehicle actuates the plurality of switches while the operator is operating the pneumatic control mechanism.

  • Patent number: 10196206
    Abstract: An automatic control system for a refuse vehicle includes a mode select switch disposed within the vehicle that generates a mode select signal based on input from an operator of the vehicle, a control mechanism disposed within the vehicle that operates in response to the mode select signal, and a plurality of sensors adapted to sense a plurality of characteristics of the vehicle and adapted to communicate the plurality of sensed characteristics. The system further includes a control module that receives control instructions from the control mechanism and selectively controls at least one component of a plurality of components of the vehicle based on the mode select signal, at least one of the plurality of sensed characteristics, and the control instructions.
