Patent number: 12006140Abstract: 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.Type: GrantFiled: May 25, 2023Date of Patent: June 11, 2024Assignee: Oshkosh CorporationInventors: Jeffrey Koga, Emily Davis, Jerrod Kappers, Vince Schad, Robert S.

Patent number: 12007793Abstract: A refuse vehicle system includes a refuse vehicle, a drone, and a controller. The drone includes a GPS and a sensor configured to provide data relating to a status of refuse within a scan area. The controller is configured to receive data from the sensor of the drone, determine the status of refuse within the scan area based on the data from the sensor of the drone, and at least one of generate a route for the refuse vehicle based on the status of refuse within the scan area, modify a route for the refuse vehicle based on the status of refuse within the scan area, and provide a signal to the refuse vehicle regarding the status of refuse within the scan area.Type: GrantFiled: April 16, 2021Date of Patent: June 11, 2024Assignee: Oshkosh CorporationInventors: Jeffrey Koga, Emily Davis, Jerrod Kappers, Vince Schad, Robert S.

Patent number: 9915991Abstract: A power state management system of an electronic system is coupled to a plug load device and a method for operation of the same. The system includes a context clock to adjust a duty cycle of the electronic system for controlling the power states of the electronic system for more efficient use of electricity. The context clock is responsive to user input, multiple event driven activities or an external protocol determined policy or command. Interface circuitry communicates user input, multiple event driven activities or an external protocol determined policy or command to the context clock. Interface circuitry also communicates commands to the managed plug load device or devices.Type: GrantFiled: March 14, 2014Date of Patent: March 13, 2018Assignee: The Regents of the University of CaliforniaInventors: Yang Arthur Zhang, Guann Pyng Li, Zachary Davis, Christopher Hurst, Jieping Guo
