Filed:

Mar 9, 1999

Appl. No.:

09/265435

Inventors:

Caleb Clark Crye - NY NY 10018
Dmitry Yavid - Brooklyn NY
Efrain Luke Rodriguez - Brooklyn NY

Assignee:

Caleb Clark Crye - Brooklyn NY

International Classification:

F41A 1706

US Classification:

42 7006, 42 7008, 42 7001

Abstract:

A firearm safety and control system and a safety magazine therefor are described. In one embodiment, a safety magazine disposed within a firearm disables or enables a firing control mechanism in the firearm upon sensing or not sensing the presence of, or communicating or not communicating with, an external communication and/or enabling device. In another embodiment, the safety magazine locks itself into or unlocks itself from the frame of the firearm upon sensing or not sensing the presence of, or communicating or not communicating with, an external communication and/or enabling devices. The safety magazine may be configured to be received in unmodified, existing, stock firearms.

Appl. No.:

8/259339

Inventors:

Robert L. Borchardt - New York NY
William T. McGreevy - Babylon NY
Ashok Nawarange - Astoria NY
Efrain L. Rodriguez - Brooklyn NY

International Classification:

H04B 100

US Classification:

455 42

Abstract:

Systems, methods and apparatus are provided for conducting local wireless audio signal transmissions from a local audio signal source to a person within a local signal transmission area. In certain embodiments, the transmissions are conducted over the 900 MHz local transmission band to a portable receiver unit supported on the headband of a stereo headphone unit. The receiver unit serves to down convert the 900 MHz signal to a local frequency band which is received by an FM receiver of the receiver unit which serves to reproduce the audio signals therefrom which are, in turn, converted to acoustic signals by electroacoustic transducers of the headphone. A transmitter unit includes a ceramic resonator stabilized FM transmitter, as well a filter for suppressing high frequency noise in an audio modulation signal, a stereo audio multiplexing unit utilizing a 3f. sub. H subcarrier and an overmodulation detection unit. In certain embodiments, the receiver unit is powered by a rechargeable battery which is recharged from the transmitter unit.

Appl. No.:

7/947705

Inventors:

Robert L. Borchardt - New York NY
William T. McGreevy - Babylon NY
Efrain Rodriguez - Brooklyn NY

Assignee:

Recoton Corporation - Long Island City NY

International Classification:

H04B 1000

US Classification:

359145

Abstract:

Systems, methods and devices are provided for remotely transmitting a control command to a device having a light sensor for receiving the control command in the form of a light energy signal. A radio frequency remote control signal is produced within an enclosure of a remote control unit (such as a hand-held remote control unit) and is radiated therefrom to a radio frequency receiver. The receiver converts the received signal to a light energy signal which it applies to the light sensor of the device to provide the command thereto.

Assignee:

Recoton Corporation - Long Island City NY

International Classification:

H04N 704

US Classification:

348485

Abstract:

A transmission apparatus and method for transmitting stereo multiplexed audio signals from a received television signal having a horizontal frequency f. sub. H are provided. Right and left channel audio signals obtained by demodulation from the received television signal are added to form a first combined audio signal. The same signals are subtracted to form a second combined audio signal. A subcarrier is modulated with one of the first and second combined audio signals, the subcarrier having a frequency substantially equal to 3f. sub. H to form a subcarrier modulated audio signal. The other of the first and second combined audio signals is combined with the subcarrier suppressed signal to form a stereo multiplexed audio signal, and the stereo multiplexed audio signal is transmitted.
