Object Identification System And Method Utilizing Radiometry

View page
US Patent:
48720143, Oct 3, 1989
Filed:
Jan 31, 1985
Appl. No.:
6/696716
Inventors:
Markus Nowogrodzki - Sussex NJ
Assignee:
General Electric Company - Schenectady NY
International Classification:
G01S 302
G01S 1374
US Classification:
342351
Abstract:
The totally passive object identification system and method involves the use of a radiometer to produce a signal corresponding to the radiation pattern generated by an object of interest in the frequency band to which the radiometer is sensitive, and involves comparing the produced signal with a signal corresponding to a given class of objects. The comparator produces a signal indicative of correspondence or a lack of correspondence between the object of interest and the given class of objects.

Surface Roughness Measuring Apparatus

View page
US Patent:
41480279, Apr 3, 1979
Filed:
Mar 27, 1978
Appl. No.:
5/890802
Inventors:
Markus Nowogrodzki - Sussex NJ
Assignee:
RCA Corporation - New York NY
International Classification:
G01S 902
US Classification:
343 5SA
Abstract:
A doppler radar of the type normally used to measure relative speed between a transmitter and a reflector is mounted so that its antenna is directed toward the surface to be measured. The radar is coupled to a means for de-emphasizing the doppler shift frequencies of the return signal associated with the speed of the vehicle and emphasizing the lower frequency components of the back scattered signal. The energy contained in these components provides an indication of the roughness of the surface which is in relative motion to the radar.

Wheel Wear Measurement System

View page
US Patent:
44322291, Feb 21, 1984
Filed:
Jun 4, 1982
Appl. No.:
6/385055
Inventors:
Markus Nowogrodzki - Sussex NJ
Assignee:
RCA Corporation - New York NY
International Classification:
G01M 1700
US Classification:
73146
Abstract:
A system for measuring wheel wear of a railroad vehicle includes a first speed measuring device, such as a microwave doppler speed sensor for measuring speed of the vehicle independent of wheel rotation rate, a second speed measuring device for measuring vehicle speed in terms of wheel rotation rate and a comparison device for measuring the difference of the two speed signals over time to therefore provide a signal indicative of wheel wear.

Channelized Frequency Memory System Employing Feedback

View page
US Patent:
44841558, Nov 20, 1984
Filed:
Mar 31, 1982
Appl. No.:
6/363867
Inventors:
Markus Nowogrodzki - Sussex NJ
Assignee:
RCA Corporation - New York NY
International Classification:
G01S 730
H03B 500
US Classification:
331 49
Abstract:
A frequency memory module responsive to an input relatively short duration RF burst signal of center frequency f for producing an output signal at center frequency f for a relatively long duration includes a narrow band filter tuned to pass frequency f which is receptive of the input signal, an amplifier connected to the output of the filter and feedback means connected from the output of the amplifier to the input of the filter. Because of the feedback the frequency memory module sustains oscillations at frequency f long after the input pulse is removed from the filter.

Frequency Translation Means

View page
US Patent:
42478227, Jan 27, 1981
Filed:
Jan 4, 1979
Appl. No.:
6/000812
Inventors:
Markus Nowogrodzki - Sussex NJ
Assignee:
RCA Corporation - New York NY
International Classification:
H03B 2101
US Classification:
328 15
Abstract:
A method and means for translating frequencies, as for example, to correct a frequency error. DELTA. f. sub. d introduced into a carrier signal of frequency f. sub. c, comprising means for dividing the resultant signal frequency (f. sub. c +. DELTA. f. sub. d) by N, resulting in a divided-down frequency (f. sub. c /N+. DELTA. f. sub. d /N), with. DELTA. f. sub. d being reduced to. DELTA. f. sub. d /N, and then heterodyning the divided-down frequency with signal of frequency (f. sub. c +f. sub. c /N) to produce a resultant signal of frequency (f. sub. c +. DELTA. f. sub. d /N), the frequency error remaining at its low, divided level. DELTA. f. sub. d /N. In the case of two or more signals spaced apart by predetermined frequency spacings, such frequency spacings can be reduced to predetermined values by dividing said signals by a common divisor M with the frequency spacings also being divided by M and then heterodyning the divided-down frequencies upwardly to desired frequencies with the frequency spacings remaining at their desired reduced values.

Dual Frequency Heart Rate Monitor Utilizing Doppler Radar

View page
US Patent:
45137480, Apr 30, 1985
Filed:
Aug 30, 1983
Appl. No.:
6/527768
Inventors:
Markus Nowogrodzki - Sussex NJ
Daniel D. Mawhinney - Livingston NJ
Assignee:
RCA Corporation - Princeton NJ
International Classification:
A61B 502
US Classification:
128653
Abstract:
A heart rate monitor for use where direct contact with a patient cannot be made utilizes two continuous radio frequency (RF) signals, one of relatively low frequency and one of relatively high frequency directed toward the patient whose heart is to be determined. Doppler shifted signals are reradiated by the patient back to the monitor. The reradiated low RF signal has doppler components due to bodily motion caused by respiration and heartbeat. The reradiated high RF signal has doppler components due to patient bodily movement caused by respiration. Doppler components due to heartbeat if any, are of substantially lower value than those associated with the low RF signal. The heart rate monitor includes a difference amplifier which effectively subtracts the doppler signal associated with the high RF frequency from the doppler signal associated with the low RF frequency to obtain a signal which contains only components due to the heartbeat of the patient.

Microwave Delay Line

View page
US Patent:
39551580, May 4, 1976
Filed:
Feb 27, 1974
Appl. No.:
5/446418
Inventors:
Lakshminarasimha Chainulu Upadhyayula - East Windsor NJ
Markus Nowogrodzki - Sussex NJ
Assignee:
RCA Corporation - New York NY
International Classification:
H03H 744
H03H 900
H04B 318
US Classification:
333 29
Abstract:
A predetermined delay is provided for a microwave input signal by a delay line having a frequency divider circuit including a negative resistance semiconductor device responsive to the microwave input signal and a D. C. bias voltage. The frequency divider circuit converts the input signal at frequency f. sub. 1, to a signal at a frequency, f. sub. 2, within the operating range of an acoustic delay device coupled to the frequency divider circuit. A frequency multiplier circuit coupled to the acoustic delay device multiplies the frequency, f. sub. 2, of the delayed signal from the acoustic device to the frequency, f. sub. 1, of the input signal.

Enemy Signal Detection And Warning System

View page
US Patent:
53432053, Aug 30, 1994
Filed:
May 30, 1986
Appl. No.:
6/868993
Inventors:
Markus Nowogrodzki - Sussex NJ
Assignee:
General Electric Company - Syracuse NY
International Classification:
G01S 1378
US Classification:
342 45
Abstract:
An enemy radar or transmitter transmits a signal at frequency f1. A tag on a friendly forces target receives frequency f1 and, in response thereto, transmits a signal at frequency f2. noteq. f1 modulated by a code unique to the tag. A friendly forces receiver, in response to receiving frequency f2 provides an indication that (a) the tag has received frequency f1, meaning the enemy is operating in the area, and (b) which specific tag has received a signal at frequency f1. The friendly forces can then take appropriate action.
