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.

Abstract: The invention relates to a system and/or an apparatus for an improved helmet system that may help reduce the severity of injuries by enhancing overall helmet protection through uniquely designed facemasks and facemask bumpers. The facemask and facemask bumpers that are particularly adapted to redistribute pressure and impact forces, decrease vibration, sudden shock, noise and/or the peak forces transmitted from the facemask to the rest of the helmet system. The facemask bumpers may be disposed into specific regions of the facemask, including the brow region, the glabella region, orbit region, the frontal region, the mandible (front, right and/or left side) region, the maxilla region, the nasal region, zygomatic region, the ethmoid region, the lacrimal region, the sphenoid region and/or any combination thereof.

Abstract: An in-ear device is implemented as part of an audio system to present a user with improved audio content within an artificial reality system. The in-ear device is a fully integrated device with an internal microphone, an external microphone, and a transducer in which portions of the transducer form portions of the body of the device. This integration of transducer into the body of the in-ear device reduces the size of the in-ear device and allows for placement deeper within the ear canal of the user. The transducer generates audio content based on instructions received from an audio system that may be located on a device that is external to the in-ear device. The external microphone provides hear-through functionality, while the internal microphone provides feedback information to the audio system.

Abstract: A three-dimensional microlattice layer comprising a plurality of interconnected filaments extending along at least three different directions from a plurality of nodes. The microlattice layer may further comprise at least one material layer extending laterally between and interconnecting at least two or more nodes. The at least one material layer may be configured to transversely and rotationally constrain the nodes to increase the overall compressive strength and stiffness of the microlattice structure. The at least one material layer may comprise a single, continuous layer and/or a plurality of material layer segments. The microlattice layer may comprise a single, continuous layer or a plurality of microlattice layer segments. The microlattice layer may be stacked, the stacked microlattice layers may further comprise one or more material layers and/or one or more impact mitigation layers.

Abstract: Disclosed is a chest drainage system which reduces or eliminates pooling of blood/liquid and/or clogging/clotting in the drainage tube and/or chest tube, and provides objective and accurate measures of drained fluid volume and chest air leak. The chest drainage system continuously monitors chest tube and drainage tube status and clears pooled liquid in the drainage tube, and/or a clogged chest tube when necessary to restore negative pressure to the chest.
