Filed:

Jul 31, 1985

Appl. No.:

6/760790

Inventors:

Christopher R. Webster - Pasadena CA

Assignee:

The United States of America as represented by the Administrator of the
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

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 5/055

Abstract:

A cervical collar having an anterior component including a main support, an intermediate support pivotally connecting to the main support at a rear portion of the anterior component, and forming a frontal opening with the main support. An adjustment mechanism connects the main support to the intermediate support and locks a position of the intermediate support relative to the main support at a front portion of anterior component. The adjustment mechanism has an actuator for disengaging the main support from the intermediate support at the front portion and permits the intermediate support to pivot relative to the main support at the rear portion to vary a height of the frontal opening. A posterior component of the cervical collar is adapted to provide improved anterior-posterior and lateral occipital support.

International Classification:

A61F 5/055
A61F 5/01

Abstract:

A cervical collar has an anterior component including a lower support that is adjustable in angle relative to a main support. The lower support is hingedly connected to the main support at first and second end portions. An elongate element engages the first and second end portions. A lock mechanism is operatively connected to the elongate element, and is arranged for locking rotation of the lower support relative to the main support, by moving the elongate element between locked and unlocked conditions. An upper support is received by the main support at least at a front section of the main support, and is arranged to be fitted against a user's chin.

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.
