Patent number: 10323347Abstract: A pallet drive system is provided that is operable for use on a sewing system. The pallet drive system has a pallet that is configured to hold a work-piece in position. A pair of alignment posts is coupled to the pallet. In exemplary aspects, each alignment post has a shape with surfaces extending in three dimensions along x, y and z axes. A corresponding pair of gripping fingers is coupled to a sewing machine, corresponding to each alignment post, that are moveable between an open position, allowing the alignment post to be positioned between the gripping fingers, and a closed position where the gripping fingers surround the alignment post. The gripping fingers define a cavity in the closed position to surround the alignment post in the x, y and z axes.Type: GrantFiled: February 10, 2016Date of Patent: June 18, 2019Assignee: NIKE, Inc.Inventors: Michael D.

Publication number: 20160229514Abstract: Various systems, processes, and techniques may be used for producing a long modular window assembly for an aircraft. In particular implementations, a long modular window assembly may, among other things, include a frame, a motor, and a shade. The frame may include an inner shell and an outer shell. The inner shell may have a lens opening, and the outer shell an opening but no lens. The frame may have a frame interior. A lens may be provided for engagement to the lens opening of the inner shell. A multiplicity of brackets may attach the frame to engage the assembly to a side wall, typically curved, of an aircraft interior. An electric motor may engage the frame in the frame interior along the frame. A first shade is provided with a shade rail. The shade and the shade rail are dimensioned for receipt into the interior of the frame.Type: ApplicationFiled: August 21, 2015Publication date: August 11, 2016Inventors: NICHOLAS C.

Patent number: 8459815Abstract: A stage lighting lamp unit includes a processor for receiving control data from a remote console. Beam orientation data for the lamp unit is passed to the lamp in the form of the x, y and z co-ordinates of a point in space through which the beam is to pass. The processor divides the required lamp travel into a number of stages dependent on execution duration data sent with the position data, and calculates, for each stage, a new value for pan and tilt angles for the lamp. These values are passed to pan and tilt controlling co-processors which control servo-motors for pan and tilt operation. The lamp unit also incorporates a rotatable shutter for interrupting the lamp beam when required. The shutters of all the lamps in a system can be instructed from the remote console to open and close in synchronism, thereby providing a stroboscopic effect.Type: GrantFiled: June 7, 2011Date of Patent: June 11, 2013Assignee: Production Resource Group, L.L.CInventors: Mark A.
