  • Patent number: 12006140
    Abstract: A refuse vehicle includes a chassis, an energy storage device, a vehicle body, an electric power take-off system, and a hydraulic component. The energy storage device is supported by the chassis and is configured to provide electrical power to a prime mover. Activation of the prime mover selectively drives the refuse vehicle. The vehicle body is supported by the chassis, and includes an on-board receptacle for storing refuse therein. The electric power take-off system is positioned on the vehicle body, and includes an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power. An amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump. The hydraulic component is in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system.

  • Patent number: 6956495
    Abstract: A control system for remotely activating an automatically opening door according to the present invention includes a plurality of transmitters held by different people and each transmitter transmits control signals. The system further includes a plurality of doors at least some of which are mounted in different buildings. Each of the doors includes an actuator for automatically opening and closing the door and a receiver electrically coupled to the actuator for receiving control signals from the transmitters and activating the actuator to open the door in response to the receipt of the control signals. In this system, any one of the transmitters may be used to open any of the doors.
