US Patent:

7355178, Apr 8, 2008

Filed:

Jun 22, 2005

Appl. No.:

11/158683

Inventors:

Charles E. Everest - Tucson AZ, US

International Classification:

G01J 5/00
G01J 5/02

US Classification:

2503381, 250353

Abstract:

A conventional infrared thermometer is equipped with a visible light source having exactly the same size and shape as the infrared detector to illuminate the target so as to visibly identify the area to be thermally measured. The light source is judiciously positioned within the system so as to make the images of the detector and the source formed by achromatic zooming optics coincide on the target surface. As a result, the exact location and dimensions of the target area under test are precisely identified and the system can perform errorless measurements of targets located at variable distances from the thermometer. Alternatively, the system is enabled to errorlessly measure the same target with variable spatial resolution.

Appl. No.:

5/866533

Inventors:

Charles E. Everest - Santa Ana CA

Assignee:

Telatemp Corporation - Fullerton CA

International Classification:

D1004

US Classification:

D10 57

US Patent:

49078950, Mar 13, 1990

Filed:

Mar 31, 1988

Appl. No.:

7/176170

Inventors:

Charles E. Everest - Santa Ana CA

Assignee:

IVAC Corporation - San Diego CA

International Classification:

G01J 506
G01J 562

US Classification:

374130

Abstract:

The infrared thermometer optical chopper includes a planar shutter having infrared radiation transmissive and infrared reflective portions arranged on the shutter, and a mechanism for rotating the shutter sequentially through a series of stop positions in which the transmissive and reflective portions are sequentially aligned with the internal optics of the infrared thermometer. A mechanism is also preferably provided for sensing the positioning of the shutter at the stop positions, to determine whether the shutter stop position alignment is in an infrared radiation transmissive phase or in an infrared radiation reflective phase.

Filed:

Jul 30, 1976

Appl. No.:

5/710124

Inventors:

Charles Eugene Everest - Santa Ana CA

Assignee:

Telatemp Corporation - Fullerton CA

International Classification:

G01J 500

US Classification:

250338

Abstract:

A movable instrument intended for utilization in detecting a difference which is capable of being optically detected between adjacent locations can be constructed so as to include an optical sensor for producing an output which is proportional to the difference between various locations and an illumination source operatively connected to the optical sensor for providing a level of brightness which is proportional to the output of the optical sensor. Such an instrument is preferably a device which is used in determining the temperature of a surface. When the invention is utilized in conjunction with such an instrument the apparent intensity of the light emitted from the illumination source provides a convenient analog indicator facilitating the instrument being pointed at either the hottest or coldest portion of the surface.

Appl. No.:

6/069269

Inventors:

Charles E. Everest - Santa Ana CA

International Classification:

G01J 516

US Classification:

73355R

Abstract:

A temperature measuring apparatus or device for measuring the temperature of an object or a series of closely adjacent objects through the measurement of relative infrared radiation is normally referred to as an infrared thermometer. Known infrared thermometers can be modified so as to be useful in making stress-degree measurements as are needed in determining when plants or crops should be watered or irrigated by including within such devices a temperature detector capable of providing an electrical signal. Such modified thermometers include a circuit which relates the signal produced by the temperature detector to the signal produced by the infrared radiation detector used in such a device so as to display the difference between the temperature detected by the infrared detector used and the temperature detected by the temperature detector.

Filed:

Oct 27, 1989

Appl. No.:

7/428416

Inventors:

Charles E. Everest - Santa Ana CA

Assignee:

IVAC Corporation - San Diego CA

International Classification:

A61B 122
G01K 108

US Classification:

128 9

Abstract:

A disposable cone channel insertion probe is adapted for use in combination with an infrared thermometer. The probe has a generally frusto-conical hollow body portion, an inner reflective surface, and a flange projecting radially outward from the rearward end of the probe. The infrared thermometer also includes a mechanism for retaining the probe and optics for further focusing and collimating the infrared light from the probe to an infrared sensor.

International Classification:

G01J 504
G01J 506

US Classification:

374133

Abstract:

An infrared thermometer primarily for agricultural applications utilizes an additional infrared sensor oriented for detection of sky radiation to compensate for reflection of sky radiation from the plant or other object to which the thermometer is directed. Preferably implemented in a gunlike, hand-held instrument, the invention utilizes a potentiometer for adjusting the signal level derived from a wide-angle, sky-directed sensor to account for changes in plant reflectivity characteristics. The adjusted signal is then summed with the signal derived from the conventional object-directed sensor to produce a composite signal which is applied to a meter-like device for display of object temperature with improved accuracy.
