Filed:

Sep 23, 2010

Appl. No.:

12/888858

Inventors:

Andrew Wilson - Allison Park PA, US
Andrew Punnoose - Ashburn VA, US
Katherine Strausser - Houston TX, US
Neil Parikh - North Brunswick NJ, US

Assignee:

International Classification:

H02K 51/00
H02K 16/02
H02K 7/116

US Classification:

310 83, 310114, 31015433, 475331

Abstract:

A directed flux motor described utilizes the directed magnetic flux of at least one magnet through ferrous material to drive different planetary gear sets to achieve capabilities in six actuated shafts that are grouped three to a side of the motor. The flux motor also utilizes an interwoven magnet configuration which reduces the overall size of the motor. The motor allows for simple changes to modify the torque to speed ratio of the gearing contained within the motor as well as simple configurations for any number of output shafts up to six. The changes allow for improved manufacturability and reliability within the design.

Assignee:

United States of America as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC

International Classification:

B25J 5/00

US Classification:

31856812, 3185682

Abstract:

A mobile robotic unit features a main body, a plurality of legs for supporting the main body on and moving the main body in forward and reverse directions about a base surface, and a drive assembly. According to an exemplary embodiment each leg includes a respective pivotal hip joint, a pivotal knee joint, and a wheeled foot adapted to roll along the base surface. Also according to an exemplary embodiments the drive assembly includes a motor operatively associated with the hip and knee joints and the wheeled foot for independently driving pivotal movement of the hip joint and the knee joint and rolling motion of the wheeled foot. The hip joint may include a ball-and-socket-type joint interconnecting top portion of the leg to the main body, such that the hip joint is adapted to pivot said leg in a direction transverse to a forward-and-reverse direction.

International Classification:

F16H 19/08

US Classification:

74 33

Abstract:

A joint assembly is provided which includes a drive assembly and a swivel mechanism. The drive assembly features a motor operatively associated with a plurality of drive shafts for driving auxiliary elements, and a plurality of swivel shafts for pivoting the drive assembly. The swivel mechanism engages the swivel shafts and has a fixable element that may be attached to a foundation. The swivel mechanism is adapted to cooperate with the swivel shafts to pivot the drive assembly with at least two degrees of freedom relative to the foundation. The joint assembly allows for all components to remain encased in a tight, compact, and sealed package, making it ideal for space, exploratory, and commercial applications.

Appl. No.:

15/080582

Inventors:

Philip Krim - New York NY, US
Neil Parikh - Toms River NJ, US
Jeff Chapin - Providence RI, US

International Classification:

A47C 27/15
A47C 21/04

Abstract:

A foam mattress in which a layer of latex or latex-like foam placed above a layer of memory foam is described. This construction of the mattress provides the contouring pressure relief that a visco-elastic foam provides with a top surface with quick recovery (a latex-like “bounce”) that prevents people from getting “stuck” in the visco-elastic foam and improves the springiness of the mattress. The mattress may also include straps and cinches to aid in transportation of the mattress. The mattress may also include removable covers that aid in keeping the mattress clean.
