  • Publication number: 20240161552
    Abstract: A refuse vehicle includes multiple systems, each system including a sensor. The refuse vehicle also includes an automated check system. The automated check system includes processing circuitry configured to obtain sensor data from the sensor of each of the multiple systems, determine which of the multiple systems require manual inspection based on the sensor data, and operate a display screen to prompt a technician to manually inspect one or more of the multiple systems.

  • Publication number: 20240116705
    Abstract: An electric power take-off system includes a motor configured to convert electrical power received from a battery into hydraulic power, an inverter configured to provide electrical power to the motor from the battery, a heat dissipation device in thermal communication with the inverter, wherein the heat dissipation device includes a thermal fluid pump configured to pump cooling fluid through a plurality of conduits, a flow meter configured determine a flow rate through the plurality of conduits, and a controller configured to receive data from the flow meter and provide operating parameters to the heat dissipation device, wherein the controller is further configured to determine if the data from the flow meter is less than a critical operating condition and decrease the hydraulic power provided by the electric power take-off system in response to determining that the data from the flow meter is less than the critical operating condition.

  • Publication number: 20240111290
    Abstract: A system for detecting and engaging a refuse can includes at least one sensor positioned on a refuse collection vehicle and configured to detect objects on one or more sides of the refuse vehicle, an actuator assembly configured to actuate to engage the refuse can, and a controller configured to detect, using a single-stage object detector, the presence of the refuse can based on first data received from the at least one sensor, determine, based on the first data, a position of the refuse can with respect to the refuse collection vehicle, generate a first trajectory from the refuse collection vehicle to the position of the refuse can, generate a second trajectory for the actuator assembly, and initiate a control action to move at least one of the refuse collection vehicle along the first trajectory or the actuator assembly along the second trajectory to engage the refuse can.

  • Publication number: 20240075815
    Abstract: A refuse vehicle includes a chassis, an energy storage device supported by the chassis and configured to provide electrical power to a prime mover, wherein activation of the prime mover selectively drives the refuse vehicle, a body for storing refuse therein supported by the chassis, a first hydraulic pump configured to convert electrical power into hydraulic power, a second first hydraulic pump configured to convert electrical power into hydraulic power, and a motor coupled to at least one of the body or the chassis and configured to drive the first hydraulic pump and drive the second hydraulic pump.

  • Patent number: 9915991
    Abstract: 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.

  • Publication number: 20070279140
    Abstract: A ?-flap type nano/micro mechanical device with a lower electrode 1,1a, 1b, an upper electrode layer 2, an dielectric layer 3 arranged between the lower electrode 1,1a,1b and the upper layer 2, such that the dielectric layer 3 and said upper electrode layer—2 form a layered body 4, the layered body 4 comprising a horizontal recess 5 in a side portion of the dielectric layer 3, and an overhanging portion 6 of reduced thickness over the recess 5 that forms a gap 5a; such that the overhanging portion 6 forms a ?-flap 6a which extends over the gap 5a. The device is a capacitative-based device in which the mechanical motion can be measured at room temperature and without monolithic integration thereof with an integrated circuit but that can be easily integrated with complementary metal oxide semiconductor (CMOS) circuitry.
