National Aeronautics and Space Administration - Washington DC

International Classification:

G01N 2117

US Classification:

356409

Abstract:

A simple optomechanical method and apparatus is described for substantially reducing the amplitude of unwanted multiple-interference fringes which often limit the sensitivities of tunable laser absorption spectrometers. An exterior cavity is defined by partially-transmissible surfaces such as a laser exit plate, a detector input, etc. That cavity is spoiled by placing an oscillating plate in the laser beam. For tunable diode laser spectroscopy in the mid-infrared region, a Brewster-plate spoiler allows the harmonic detection of absorptances of

G01J 3443
G01N 2166

US Classification:

356311

Abstract:

Disclosed is a method and apparatus for an optogalvanic spectroscopy system. Orthogonal geometry exists between the axis of a laser probe beam and the axis of a discharge created by a pair of spaced-apart and longitudinally aligned high voltage electrodes. The electrodes are movable to permit adjustment of the location of a point in the discharge which is to be irradiated by a laser beam crossing the discharge region. The cell dimensions are selected so that the cross-section of the discharge region is substantially comparable in size to the cross-section of the laser beam passing orthogonally through the discharge region.

International Classification:

A61F 5/01

Abstract:

An orthopedic device has first and second struts connected to one another by a hinge system, and includes a dynamic control system and a counterforce system. The dynamic control system includes first and second dynamic components arranged on a first side of the orthopedic device to exert first and second dynamic forces according to a flexion angle of the hinge system. A counterforce system is located on a second side of the orthopedic device to counteract the first and second dynamic forces with at least one counterforce.

Assignee:

MEDTRONIC, INC. - Minneapolis MN

International Classification:

B21D 51/16

US Classification:

29428, 29 33 K

Abstract:

A device for crimping an expandable medical device and loading the expandable medical device into a delivery system includes an actuator, a compression assembly, and a pusher. The compression assembly is disposed in a compression chamber of the actuator and includes a plurality of compression elements coupled to each other to form a central cavity. The compression elements are coupled to the actuator such that rotation of the actuator causes the compression elements to rotate such that the central cavity radially compresses from an expanded configuration to a compressed configuration. The pusher includes a pusher rod and is configured to translate relative to the actuator towards the compression chamber when the cavity is in the compressed configuration such that the pusher rod may enter the cavity and push the medical device out of the cavity into delivery system.

US Classification:

29428, 29700

Abstract:

A device for crimping an collapsible device and loading the collapsible device into a delivery system, includes a crimping tool configured to radially crimp at least a portion of the collapsible device, a loading tool configured to load at least a portion of the collapsible device into a delivery system, and a housing that houses at least one of the crimping tool and loading tool, wherein the device is configured to crimp and load the collapsible device without requiring manual repositioning of the collapsible device. Methods of crimping an collapsible device and loading the collapsible device into a delivery system are also disclosed.

Appl. No.:

13/646379

Inventors:

Christopher Harrison Webster - Kingwood TX, US

International Classification:

B32B 3/02
B32B 3/26

US Classification:

428 667

Abstract:

The present invention is an improved corkboard consisting of a small, circular, moveable and removable tack landing pad which is designed to adhere to a flat surface such as a wall or computer by an adhesive strip or to a metal surface like a refrigerator or thing cabinet via a magnetic strip. This landing pad is designed to receive papers of various sizes, shapes, and stock through puncture with a standard push pin tack without damaging walls. The landing pad consists of two components—(1) an outer donut-shaped shell that is sealed at its base and is contoured inward to a narrowing angle at its tack receiving face and (2) an inner foam core. The outer shell operates to both enclose and compress the foam core. This core compression affords the foam greater tack gripping ability as well as enhanced durability by quickly regaining its original shape upon tack removal.
