Abstract: A product on demand nozzle assembly includes a chamber at least partially defined by an external wall and an array of vertically spaced nozzles. Each nozzle has an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone between the air inlet and the air and entrained product outlet to receive a product therein to be distributed.

Abstract: A patient specific shoulder guide is provided that includes a hub and a plurality of peripheral members. Each of the peripheral members has a peripheral member height dimension between the patient specific contact surface and a side of the peripheral member opposite the patient specific contact surface. At least one of the peripheral members is a low profile peripheral member in which the peripheral height dimension is less than the peripheral height dimension of at least one other of the peripheral members or is less than the hub height.

Abstract: A patient specific shoulder guide is provided that includes a plurality of peripheral members coupled with a peripheral body. The peripheral members have a patient specific contact surface. An open space (e.g., a single open space) is or can be provided radially between a central channel and an inner periphery of the peripheral body. The open space(s) can extend from a side of a spoke to another side of the same or a different spoke. The spoke can be a single spoke in some embodiments. The single open space can extend more than 120 degrees between circumferential ends of the open space.

Abstract: In some embodiments, a cooking vessel cover device may include a body with a perimeter, upper surface, and lower surface. The body may be made from a flexible material so that portions of the body may flex to allow the device to move between the closed position and the open position. The perimeter and/or portions of the body bounded by the perimeter may contact the upper terminus of a cooking vessel when the device is in a closed position so that the perimeter and the body may be in a generally flat planar orientation. An aperture, which may be configured to receive portions of a food preparation apparatus and which may be disposed within the body, may pass through the upper surface and lower surface, thereby allowing the food preparation apparatus to operate with the cooking vessel cover in the closed position and the open position. A positioning fastener may be coupled to the body which is configured to be removably coupled to one or more objects thereby securing the device in an open position.
