Abstract
Abstract An in vivo video camera system and an autonomous video endoscope are described. Each system includes a swallowable capsule, a transmitter and a reception system. The swallowable capsule includes a camera system and an optical system for imaging an area of interest onto the camera system. The transmitter transmits the video output of the camera system and the reception system receives the transmitted video output.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
49 words
An in vivo video camera system comprising: a swallowable capsule comprising: a camera system; an optical system for imaging an area of interest onto said camera system; and a transmitter which transmits the video output of said camera system; and a reception system which receives said transmitted video output.
Claim 2
Dependent Claim
49 words
An in vivo video camera system comprising: a swallowable capsule comprising: a camera system; an optical system for imaging an area of interest onto said camera system; and a transmitter which transmits the video output of said camera system; and a reception system which receives said transmitted video output.
Claim 3
Dependent Claim
14 words
A system according to claim 1 and including means for operating said transmitter intermittently.
Claim 4
Dependent Claim
23 words
A system according to claim 1 and wherein said optical system includes a viewing window located along one side of said swallowable capsule.
Claim 5
Dependent Claim
57 words
A system according to claim 1 and wherein said reception system comprises: an antenna array capable of surrounding a body and comprising a plurality of antennas for receiving said transmitted video output and for producing a plurality of received signals; and a demodulator capable of transforming said plurality of received video signals into a single video datastream.
Claim 6
Dependent Claim
23 words
A system according to claim 4 and also comprising a data processing system which generates tracking and video data from said single datastream.
Claim 7
Dependent Claim
69 words
A system according to claim 1 and wherein said optical system comprises: an axicon optical element having a conical outer surface which, when said conical outer surface is in contact with inner walls of a flexible tube, creates a conical object on said conical outer surface, for compensating for the conical shape of said conical object; and a relay unit which relays said compensated object to said camara system.
Claim 8
Dependent Claim
26 words
A system according to claim 6 and wherein said axicon optical element has an axis of symmetry and a borehole centered around said axis of symmetry.
Claim 9
Dependent Claim
21 words
A system according to claim 6 and also comprising a light source located within said borehole of said axicon optical element.
Claim 10
Dependent Claim
39 words
A system according to claim 6 and wherein said axicon element is located before said relay unit and said camera system thereby to enter said flexible tube first and to open up said flexible tube if it has collapsed.
Claim 11
Dependent Claim
61 words
A reception system operable with a swallowable transmitting capsule, the reception system comprising: an antenna array capable of surrounding a body and comprising a plurality of antennas for receiving transmitted video output from said capsule and for producing a plurality of received video signals; and a demodulator capable of transforming said plurality of received video signals into a single video datastream.
Claim 12
Dependent Claim
61 words
A reception system operable with a swallowable transmitting capsule, the reception system comprising: an antenna array capable of surrounding a body and comprising a plurality of antennas for receiving transmitted video output from said capsule and for producing a plurality of received video signals; and a demodulator capable of transforming said plurality of received video signals into a single video datastream.
Claim 13
Dependent Claim
47 words
An autonomous video endoscope comprising: a swallowable capsule comprising: a camera system; an optical system for imaging an area of interest onto said camera system; and a transmitter which transmits the video output of said camera system; and a reception system which receives said transmitted video output.
Claim 14
Dependent Claim
47 words
An autonomous video endoscope comprising: a swallowable capsule comprising: a camera system; an optical system for imaging an area of interest onto said camera system; and a transmitter which transmits the video output of said camera system; and a reception system which receives said transmitted video output.
Claim 15
Dependent Claim
56 words
A system according to claim 11 and wherein said reception system comprises: an antenna array capable of surrounding a body and comprising a plurality of antennas for receiving said transmitted video output and for producing a plurality of received signals; and a demodulator capable of transforming said plurality of received video signals into a single datastream.
Claim 16
Dependent Claim
23 words
A system according to claim 12 and also comprising a data processing system which generates tracking and video data from said single datastream.
Claim 17
Dependent Claim
69 words
A system according to claim 11 and wherein said optical system comprises: an axicon optical element having a conical outer surface which, when said conical outer surface is in contact with inner walls of a flexible tube, creates a conical object on said conical outer surface, for compensating for the conical shape of said conical object; and a relay unit which relays said compensated object to said camara system.
Claim 18
Dependent Claim
26 words
