Abstract
Abstract An aircraft-to-weapon fuze communication link that transfers fuzing inforion between the aircraft and weapon via an optical data and power link in the absence of any physical connection. The information is transferred via an infrared light beam in digital format. Power to run the fuze receiver during the data transfer process is supplied from a high power light source.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
An optical communications link comprising; information transmitting means including an optical transmitter for transmitting information in digital format via a light beam; power transmitting means for supplying a high-power light beam; power receiver means on a receiving body for receiving the high power light beam and converting the beam to electrical energy; information receiver means included on said receiving body for receiving the information transmitted by said information transmitting means and being powered by the electrical energy from said power receiving means; and data decoder means operatively coupled to said information receiver means for decoding the information transmitted in digital format.
Claim 2
Dependent Claim
101 words
An optical communications link comprising; information transmitting means including an optical transmitter for transmitting information in digital format via a light beam; power transmitting means for supplying a high-power light beam; power receiver means on a receiving body for receiving the high power light beam and converting the beam to electrical energy; information receiver means included on said receiving body for receiving the information transmitted by said information transmitting means and being powered by the electrical energy from said power receiving means; and data decoder means operatively coupled to said information receiver means for decoding the information transmitted in digital format.
Claim 3
Dependent Claim
33 words
An optical communication link as set forth in claim 1 wherein; said information transmitting means includes encoding means for receiving a binary digital word and converting it to a trinary pulse-number modulated code.
Claim 4
Dependent Claim
30 words
An optical communications link as set forth in claim 2 wherein; said information transmitting means comprises a light-emitting diode that is pulsed with the modulated word from the encoding means.
Claim 5
Dependent Claim
37 words
An optical communications link as set forth in claim 1 wherein; said information receiver means includes temporary storage means coupled to the output of said data decoder means for temporarily storing the output of said data decoder.
Claim 6
Dependent Claim
34 words
An optical communications link as set forth in claim 4 and further including; parity checking means operatively coupled to the output of said temporary storage means for checking the parity of the decoded data.
Claim 7
Dependent Claim
21 words
An optical communications link as set forth in claim 1 and further including; temporary power storage means in said receiving body.
Claim 8
Dependent Claim
35 words
An optical communications link as set forth in claim 4 and further including; temporary power storage means in said receiving body and having an output operatively coupled as an input to said temporary storage means.
Claim 9
Dependent Claim
39 words
An optical communications link as set forth in claim 5 and further including; default circuit means operatively coupled to said parity checking means for controlling the flow of data from said temporary storage means dependent on the parity check.
Claim 10
Dependent Claim
45 words
An optical communications link as set forth in claim 8 and further including; control register means operatively receiving the output of the temporary storage means via the parity checking means and default circuit means for storing the decoded digital word and removing parity bits therefrom.
