An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening.

Abstract: A method of manufacturing cross-corrugated support structures is provided. A mold having a molding surface with a first plurality and a second plurality of corrugations therein is used to introduce corrugations into a flexible, carbonaceous sheet. Cross-corrugations are introduced into the sheet by placing the sheet onto the molding surface, encapsulating the sheet to form a vacuum chamber, and evacuating the vacuum chamber of air. As air is evacuated from the vacuum chamber, the sheet is drawn upon the molding surface causing the sheet to conform to the shape of the molding surface. Thermosetting resin is infused into the sheet and cured causing the sheet to rigidly retain the shape of the molding surface. The sheet is further reinforced by securing at least one support member to the sheet using thermosetting resin.

Abstract: Embodiments relate to cylindrical MRI coils with at least one row as a birdcage row in a transmit mode. One example embodiment is a MRI Radio Frequency (RF) coil array comprising two or more rows of four or more RF coil elements each. Each of the RF coil elements can be configured to resonate at a working frequency of the coil array in a receive mode. At least one of the rows can be configured as a birdcage coil in the transmit mode, and the two or more rows can inductively couple together such that all the two or more rows can resonate together in the transmit mode at the working frequency.

Abstract: A valve assembly includes a first housing that defines an inlet and a fluid output chamber. A second housing is engaged to the first housing and a cover is engaged to the second housing. A valve member is positioned within the first housing. An actuator is positioned between the second housing and the cover and is attached to the valve member through an engagement located within the first housing. A flow rate sensor, as a component of the valve assembly, may be positioned downstream of the inlet and the fluid output chamber.

Abstract: A deep neural network (DNN) module utilizes parallel kernel and parallel input processing to decrease bandwidth utilization, reduce power consumption, improve neuron multiplier stability, and provide other technical benefits. Parallel kernel processing enables the DNN module to load input data only once for processing by multiple kernels. Parallel input processing enables the DNN module to load kernel data only once for processing with multiple input data. The DNN module can implement other power-saving techniques like clock-gating (i.e. removing the clock from) and power-gating (i.e. removing the power from) banks of accumulators based upon usage of the accumulators. For example, individual banks of accumulators can be power-gated when all accumulators in a bank are not in use, and do not store data for a future calculation. Banks of accumulators can also be clock-gated when all accumulators in a bank are not in use, but store data for a future calculation.

Abstract: A lumber culling system may include a carriage with a distal wall and a proximal wall spaced apart from one another to form an interior of the carriage. An aperture may extend through the distal wall and the proximal wall. The aperture is sized and shaped to allow a board of wood to pass through the distal wall and the proximal wall. Further, the interior of the carriage is visible within the aperture. Imaging equipment may be disposed within the interior of the carriage and arranged to scan a portion of each side of the board of wood that is positioned within the aperture. The carriage may be moved along a length of the board of wood while the board of wood is at rest on static datum supports.

Abstract: Enclosed are embodiments for scoring one or more trajectories of a vehicle through a given traffic scenario using a machine learning model that predicts reasonableness scores for the trajectories. In an embodiment, human annotators, referred to as a “reasonable crowd,” are presented with renderings of two or more vehicle trajectories traversing through the same or different traffic scenarios. The annotators are asked to indicate their preference for one trajectory over the other(s). Inputs collected from the human annotators are used to train the machine learning model to predict reasonableness scores for one or more trajectories for a given traffic scenario. These predicted trajectories can be used to rank trajectories generated by a route planner based on their scores, compare AV software stacks, or used by any other application that could benefit from a machine learning model that scores vehicle trajectories.
