Filed:

Sep 1, 1989

Appl. No.:

7/401692

Thomas G. Conway - Woodbridge VA

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

F41H 300

US Classification:

428 17

Abstract:

A three-color camouflage system comprises layers of camouflage material hng low, intermediate and high thermal emissivities in the infrared spectral range, and appearing black, green and brown in the visible spectral range. The camouflage surface is structured in such manner that there is color adaptation to the natural background in the visible spectral range, as well as adaptation to the natural background in thermal emissivity in the infrared spectral range so that targets cannot be recognized with infrared sensing devices. Thermal emissivity in the infrared spectral range is controlled by superimposing layers of intermediate and high emissivity onto a basic low emissivity camouflage layer and providing perforations in these layers allowing the low-emissivity layer to be seen. High-emissivity areas are provided by perforations allowing the high-emissivity surface of the object being camouflaged to be seen. Alternatively, spots of high emissivity are superimposed on the three camouflage layers to provide areas of high emissivity.

US Classification:

Abstract:

A data recovery system wherein the data is represented by a sequence of data pulses comprising a predetermined sequence of preamble pulses followed by the sequence of data pulses. The data pulses have desired data pulses and a DC offset component, each one of such data pulses having during the preamble acquisition mode a predetermined period. The system includes a clock for producing clock pulses at a predetermined rate and a negative feedback loop. The negative feedback loop includes a differencing network fed by the data pulses and a feedback signal representative of the DC offset component. The differencing network removes the DC offset component from the data pulses to produce output signal representative of the desired data pulses.

Assignee:

The United States of America as represented by the Secretary of the Army - Washington DC

International Classification:

G01J 510
G01N 2500

US Classification:

374 9

Abstract:

The emissivity of camouflage material is determined from the apparent body emperature measured by a radiometer, calibrated to indicate a temperature of a blackbody would emit corresponding to the radiation received therefrom; and the true temperature of the material and the true temperature at an infrared detector of the radiometer of a radiometer. Computation means is provided for calculating emissivity from the so measured temperatures and for displaying the result.

Appl. No.:

9/207434

Inventors:

Thomas Conway - Boulder CO

Assignee:

STMicroelectronics, N.V.

International Classification:

G11B 509

US Classification:

360 51

Abstract:

A data recovery system wherein the data is represented by a sequence of preamble pulses having a predetermined sequence followed by data pulses. An analog to digital converter converts samples of the preamble pulses and the data pulses into corresponding digital words in response to clock pulses fed to a clock input of the converter. A pair of feedback loops is coupled to an output of the analog to digital converter to produce the clock pulses for the converter; a first one during a data recovery mode and a second one during a preceding preamble acquisition mode.
