International Classification:

H04B 10/00

US Classification:

398118, 398125, 398121

Abstract:

A communications system for wireless transceiving of information, comprising an optical array subsystem for transceiving optical signals and a millimeter wave subsystem for transceiving millimeter wave signals, and a beam steering controller for controlling the direction of the optical and millimeter wave signals. The communication system may be on a flying platform, such as a satellite and may communicate with multiple remote terminals.

Abstract:

A method of determining the glomerular filtration rate of a subject comprises (1) obtaining a serum sample S. sub. pre and a urine sample U. sub. pre from a subject; (2) administering to the subject an amount of a paramagnetic substance that is filtered by the kidneys and is readily detectable by NMR in serum and urine; (3) allowing for the concentration of the substance to equilibrate between the blood and the extravascular spaces; (4) separating an aliquot of the urine sample v. sub. A and obtaining a serum sample from the subject at the time t. sub. A ; (5) calculating a urine rate (v/a). sub. A from the formula (v/a). sub. A =V. sub. A /a. sub. A ; (6) measuring the magnetic resonance relaxation times of the serum and urine samples, (7) obtaining the concentrations of the paramagnetic substance in the serum samples and the urine samples by comparing their relaxation times to a standard; and (8) calculating GFR from the formula ##EQU1##.

Abstract:

A head holder with the following characteristics: it is compatible with MR (no metallic parts); it is adjustable for use with adults and children; it does not produce any degradation of imaging or spectroscopy raw data; it does not induce claustrophobia; it can be used as a fixation device for cervical spine MR examinations; and it can operate with any MR unit. A strap is placed around the head of the patient at the forehead, is tightened, and then the head with band attached is positioned for optimal comfort and examining advantage. Lock screws are then tightened, holding the head comfortably in three-dimensional space. Only a single band is placed over the forehead of the person and the rest of the fixation is provided by adjusting and locking screws located in the base and along the sides of the holder. This prevents the patient from being able to rotate his or her head from side to side or up and down. The holder is designed to fit into the MR table.
