US Patent:

41974611, Apr 8, 1980

Filed:

Aug 17, 1978

Appl. No.:

5/934764

Inventors:

C. John Umbarger - Los Alamos NM
Michael A. Wolf - Los Alamos NM

Assignee:

The United States of America as represented by the United States
Department of Energy - Washington DC

International Classification:

G01T 122

US Classification:

250370

Abstract:

The disclosure relates to a miniaturized radiation chirper for use with a small battery supplying on the order of 5 volts. A poor quality CdTe crystal which is not necessarily suitable for high resolution gamma ray spectroscopy is incorporated with appropriate electronics so that the chirper emits an audible noise at a rate that is proportional to radiation exposure level. The chirper is intended to serve as a personnel radiation warning device that utilizes new and novel electronics with a novel detector, a CdTe crystal. The resultant device is much smaller and has much longer battery life than existing chirpers.

G01T 1142

US Classification:

250388

Abstract:

A hand-powered alternator for generating an alternating voltage provides same through a rectifier to a high capacity capacitor which stores the resultant dc voltage and drives a voltage regulator to provide a constant low voltage output for a portable radiation detection instrument. The instrument includes a Geiger-Muller detector tube whose output is fed to a pulse detector and then through an event counter and LCD driver circuit to an LCD bar graph for visual display. An audio driver and an audio output is also provided. All circuitry used is low power so that the capacitor can be readily charged to a sufficient level to provide power for at least 30 minutes. A low voltage indicator is provided on the LCD display to indicate the need for manual recharging.

Appl. No.:

7/664027

Inventors:

John N. Horne - Los Alamos NM
Michael A. Wolf - Los Alamos NM

International Classification:

F41A 962

US Classification:

42 102

Abstract:

A cartridge monitoring and display system for an automatic or semiautomatic firearm. A programmed microcontroller receives input signals from each of a slide switch and a magazine switch, which switches generate respective signals upon actuation of the firearm slide and upon insertion or withdrawal of a cartridge magazine. The microcontroller calculates the number of rounds remaining in the firearm and displays the number on an LCD display. A visible and audible warning is given when the cartridge count drops below a predetermined minimum level. The entire system is incorporated in a mounting strap which may be inserted between the frame and hand grip of a conventional semiautomatic pistol.

International Classification:

G01T 116

US Classification:

364569

Abstract:

The disclosure is directed to a wristwatch dosimeter utilizing a CdTe detector, a microprocessor and an audio and/or visual alarm. The dosimeter is entirely housable with a conventional digital watch case having an additional aperture enabling the detector to receive radiation.

International Classification:

G06F 1552

US Classification:

364527

Abstract:

A hand-holdable, battery-operated, microprocessor-based spectrometer gun includes a low-power matrix display and sufficient memory to permit both real-time observation and extended analysis of detected radiation pulses. Universality of the incorporated signal processing circuitry permits operation with various detectors having differing pulse detection and sensitivity parameters.

International Classification:

H03B 2900
H03K 384

US Classification:

331 78

Abstract:

A small battery operated nuclear spectrum simulator having a noise source nerates pulses with a Gaussian distribution of amplitudes. A switched dc bias circuit cooperating therewith generates several nominal amplitudes of such pulses and a spectral distribution of pulses that closely simulates the spectrum produced by a radiation source such as Americium 241.

US Classification:

602 42

Abstract:

A wound dressing capable of being inserted into a deep wound found on a patient is provided. The wound dressing contains a hydrogel material capable of absorbing wound exudate emitted by a deep wound and is substantially in the form of a cylinder. A support layer is mounted within the cylinder for purposes of providing support for the hydrogel material in the wound dressing. The invention also provides a syringe for inserting and removing the wound dressing from the deep wound for which it is applicable.
