Publication number: 20240395446Abstract: The present disclosure provides methods for defining a magnet array for a stellarator. In some embodiments, the magnet array, once defined, comprises a plurality of permanent magnets, where each permanent magnet of the plurality of permanent magnets is selected from a set of predetermined permanent magnet types. In some embodiments, each predetermined permanent magnet type in the set of predetermined permanent magnet types has a predetermined shape (geometry) and/or predetermined orientation angles (also known as a polarization orientation).Type: ApplicationFiled: July 31, 2024Publication date: November 28, 2024Inventors: DAVID GATES, KENNETH HAMMOND, CAOXIANG ZHU

Patent number: 12100520Abstract: Disclosed herein is a stellarator comprising two sets of coils, namely a set of encircling coils which encircle the plasma axis, and a set of shaping coils which do not encircle any other coil or the plasma. In some embodiments, the encircling coils include a structural element to maintain their shape under magnetic forces. In some embodiments, the shaping coils are mounted onto one or more structural elements which, together with the shaping coils, constitute a field shaping unit. Also disclosed is a controller which may modify the electrical current flowing in one or more subsets of the coils in order to achieve target plasma parameters. Also disclosed is a method of designing a set of shaping coils by discretizing a surface dipole or current potential distribution.Type: GrantFiled: January 18, 2024Date of Patent: September 24, 2024Assignee: THE TRUSTEES OF PRINCETON UNIVERSITYInventor: David Gates

Publication number: 20150100874Abstract: Techniques are disclosed for revealing extra margin area for paginated digital content, referred to herein as an extra margins mode. For example, the extra margins mode may be used to reveal/expose extra margin area (galley area) at the perimeter of one or more pages of an eBook or a photo of a photo album. Once galley area is exposed, a user can add content to the galley area, such as annotations using a stylus. In some cases, the extra margins mode may be configured to expose galley area for one or more pages in response to a reveal command input, such as a pinch gesture, a drag gesture, or an inward flick gesture from near the edge of a page using a stylus. The extra margins mode may also be configured to hide exposed galley areas in response to a hide command input, such as spread gesture.Type: ApplicationFiled: October 4, 2013Publication date: April 9, 2015Applicant: barnesandnoble.com llcInventors: Matthew Pallakoff, Charles Neugebauer, Lutz Gerhard, Luis D.

Publication number: 20070025110Abstract: A mounting assembly (100) for a lamp socket (105) that is adjustable, comprises a bracket (101) configured to be mechanically coupled to a luminaire assembly and a mounting plate (103) configured to attach to the lamp socket and be mechanically coupled to the bracket and selectively engage the bracket at one of a multiplicity of angular rotations. A corresponding method of aligning a lamp to a desired rotational position with respect to a luminaire, includes disengaging a mounting plate from a bracket, where the mounting plate and the bracket are coupled about a common axis of rotation, rotating the mounting plate about the axis to a rotational position corresponding to the desired rotational position of the lamp and re-engaging the mounting plate and the bracket.Type: ApplicationFiled: March 17, 2006Publication date: February 1, 2007Inventors: Damon Langlois, James Anderson, Donald Cleland, David Gates

Publication number: 20050056763Abstract: A bracket adapted to fit through a wheel of a spare tire for a vehicle is provided. The bracket includes a first plate portion, a first member, a second plate portion, and a second member. The first plate portion has at least two stud holes formed therethrough and arranged in a pattern corresponding to a wheel-stud pattern for at least one vehicle. The first member extends from the first plate portion. At least part of an exterior surface of the first member has a cylindrical shape. The first member has a first threaded portion. The second member extends from the second plate portion. The second member has a second threaded portion. The first threaded portion is adapted to mate with the second threaded portion. The bracket may be included in a kit, wherein the kit includes a container holding bracket.Type: ApplicationFiled: September 12, 2003Publication date: March 17, 2005Inventors: David Gates, Monte Morrish
