Abstract: An order to customer linking system may include a sensor to sense a position of an order, a projector and a processing unit to associate a customer with the order and to output signals causing the projector to project a customer identification image based upon the position.

Abstract: A waterfowl decoy may include a decoy body for flotation, a submersible keel projecting from the body and a keel rocker to rock the keel to form ripples in water about the body.

Abstract: A jumper apparatus may include a ring, a set of poles along the ring and a pneumatic tube. Each pole of the set of poles may have a first axial end portion inwardly extending towards a centerline of the ring, a second axial end portion outwardly extending away from the centerline of the ring and a vertical portion connecting the first axial end portion and the second axial end portion. The ring is vertically located between the first axial end portion and the second axial end portion of each pole. The pneumatic tube may extend about the set of poles over the second axial end portion of each pole.

Abstract: A backpack may include a first panel having a first panel surface facing in a direction and a second panel. The second panel has a second panel first surface and a second panel second surface opposite the second panel first surface. The second panel first surface is inconspicuous. The second panel is pivotable relative to the first panel between (1) a concealment position in which second panel second surface faces the first panel surface and (2) a safety position in which the second panel second surface faces in the. The backpack further includes a safety optic formed on one of the first panel surface and the second panel second surface.

Abstract: An apparatus may include a base configured to be connected to a light socket, a projector supported by the base to project a projection field and a three-dimensional sensor supported by the base to output a three-dimensional field measurement of the projection field.

Abstract: Kinetic energy devices, such as fans or blowers, are selected or controlled to attain a determined optimal overall average airflow for a volume within a livestock building to satisfy one or more predetermined livestock production objectives.

Abstract: A jumper apparatus may include a ring, a set of poles along the ring and a pneumatic tube. Each pole of the set of poles may have a first axial end portion inwardly extending towards a centerline of the ring, a second axial end portion outwardly extending away from the centerline of the ring and a vertical portion connecting the first axial end portion and the second axial end portion. The ring is vertically located between the first axial end portion and the second axial end portion of each pole. The pneumatic tube may extend about the set of poles over the second axial end portion of each pole.

Abstract: A jumper apparatus may include a base, a set of poles, a pneumatic tube and a cap. Each of the poles extend upwardly from the base and circumscribe a circle. The poles have axial end portions inwardly extending towards a centerline of the circle. The pneumatic tube extends about the set of poles proximate the base. The cap secures the axial end portions of the poles about the centerline, wherein the cap comprises radially extending grooves receiving the axial end portions of the poles.

Abstract: A swing may include a ring. In one implementation, the swing may include a first handle projecting from an inner side of the ring on a first side of the ring and a second handle projecting from the inner side of the ring on a second side of the ring. In another implementation, the ring may include a seat mounted to the ring and extending inwardly of the ring.

Abstract: A climbing stick system includes the first climbing stick and a second climbing stick. The first climbing stick includes a first step support having a cavity and a mouth leading to the cavity and first steps coupled to the first step support. The second climbing stick includes a second step support, second steps coupled to the second step support and a locking member having a head. One of the mouth and the locking member is rotatable between a locked position in which the head is locked within the cavity to retain the first climbing stick with respect to the second climbing stick and an unlocked position to facilitate separation of the first climbing stick and the second climbing stick.

Abstract: A climbing stick connector system includes first and second climbing sticks releasably secured to one another with first and second posts extending parallel to one another. In one implementation, the first climbing stick has a stopper having a shelf and a projection received within an aperture in one of the posts, wherein a step is pivotally secured to the post above the shelf by a fastener extending through the stopper. The first climbing stick has a V-shaped claw having spaced ears receiving the post therebetween, and the step has opposite upwardly facing concave edges.
