View page
US Patent:
7563097, Jul 21, 2009
Filed:
Sep 6, 2005
Appl. No.:
11/218583
Inventors:
Christopher Lavigna - Olney MD, US
Diann Brei - Milford MI, US
Jonathan Luntz - Ann Arbor MI, US
Anupam Pathak - Ann Arbor MI, US
Assignee:
Techno-Sciences, Inc. - Lanham MD
The Regents of the University of Michigan - Ann Arbor MI
International Classification:
F41A 33/00
US Classification:
434 16, 434 18, 42 90, 42 94, 42124, 42125, 42126
Abstract:
In a self-contained actively-controlled stabilization system within a hand-grip, all components are contained within the handgrip, and one generic handgrip can be attached to a variety of devices for a wide range of applications, thereby increasing portability, reducing weight and bulkiness, and decreasing complexity and application dependence. The handgrip includes a sensor, a controller and an actuator which preferably employs at least one shape memory alloy wire. The actuator drives a platform mechanism which may be configured such that the elevation and azimuth degrees of freedom are coupled or uncoupled. Direct, rotational and other platform mechanisms may be used with the invention.

Filed:
Mar 7, 2008
Appl. No.:
12/044104
Inventors:
Nancy L. Johnson - Northville MI, US
Alan L. Browne - Grosse Pointe MI, US
Kenneth A. Strom - Washington MI, US
Diann Brei - Milford MI, US

Assignee:
GM Global Technology Operations LLC - Detroit MI
International Classification:
G05G 5/05
G05G 5/06
G05G 5/18
G05G 5/24
US Classification:
180274, 29618704, 74535, 74577 M
Abstract:
A ratchet apparatus includes a first member, a rack, and a second member that is selectively movable in first and second directions with respect to the first member. A first pawl is mounted with respect to the first member and is biased into engagement with the rack. The first pawl and the rack are configured such that engagement of the first pawl with the rack prevents movement of the first pawl relative to the rack in the first direction. A second pawl is mounted with respect to the second member for movement therewith in the first and second directions. The second pawl is biased into engagement with the rack. The second pawl and said rack are configured such that engagement of the second pawl with the rack prevents movement of the second pawl relative to the rack in the first direction.
