US Patent:

39939952, Nov 23, 1976

Filed:

Dec 8, 1975

Appl. No.:

5/638847

Inventors:

Gerald Stanley Kaplan - Lawrenceville NJ
Alvin Seymour Clorfeine - Adelphi MD

Assignee:

RCA Corporation - New York NY

International Classification:

A61B 508
G01S 904

US Classification:

343 7ED

Abstract:

An apparatus for automatically monitoring the respiration of a subject requiring no physical connection to the subject. The use of such apparatus for automatically triggering an x-ray machine at instants of respiration extrema is also disclosed.

US Patent:

39684920, Jul 6, 1976

Filed:

Dec 26, 1974

Appl. No.:

5/536558

Inventors:

Gerald Stanley Kaplan - Trenton NJ

Assignee:

RCA Corporation - New York NY

International Classification:

G01S 924

US Classification:

343 14

Abstract:

An adaptive parameter signal processor for continuous wave radar ranging systems which provides non-quantized measurements of range. Means are provided to select a suitable portion of the difference frequency wave form, excluding any phase reversal. The period of the difference frequency is measured using the selected portion of the waveform and is converted to frequency. The frequency is, in turn, converted to range. The system parameters are automatically adjusted in accordance with the difference frequency waveform.

Appl. No.:

5/576604

Assignee:

RCA Corporation - New York NY

International Classification:

G01S 956

US Classification:

343 65SS

Abstract:

A homodyne communication system comprising an interrogating unit and a plurality of responsive remote units wherein a continuous wave RF signal is transmitted from the interrogating unit to illuminate a remote unit. The remote unit causes a return (reply) signal to be transmitted or reflected back to the interrogating unit. A sample of the transmitted (interrogation) signal is mixed with the return signal. Amplitude nulls in the mixer output signal at given relative phase relationships between interrogation and reply signals, are substantially eliminated by selectively shifting the relative phase of the signals. Also disclosed are a homodyne communication system utilizing phase modulation to impress FSK signaling on the reply signal and an automatic vehicle location system utilizing the present invention.

Appl. No.:

5/642111

Inventors:

Gerald Stanley Kaplan - Lawrenceville NJ
Andrew David Ritzie - Delran NJ

Assignee:

RCA Corporation - New York NY

International Classification:

G06F 739
H03K 500

US Classification:

2351503

Abstract:

Circuit and method for spacing the output signals from a binary rate multiplier by adjusting the rate of the internal clock of the binary rate multiplier to a value approximating (N+1) times f. sub. 0 where N represents the multiplier of the input frequency f. sub. The output signals thereby produced are substantially evenly spaced at a rate N times f. sub.

Appl. No.:

5/769337

Inventors:

Gerald Stanley Kaplan - Lawrenceville NJ

Assignee:

RCA Corporation - New York NY

International Classification:

G01S 956
G01S 958

US Classification:

343 65R

Abstract:

A clutter immune radar where the interrogating unit transmits a modulated interrogation signal to a remote unit, which radiates an information-bearing reply signal, in order to enable the interrogating unit to obtain remote unit information and range by the use of three bandpass filter channels where one bandpass filter bandwidth is equal to the sum of the other two bandwidths.
