Abstract
Abstract An energy saving device for acquiring in vivo images of the gastro-intestinal tract is provided. The device, such as an autonomous capsule ( 10 ), includes at least one imaging unit ( 12 ), a control unit ( 14 ) connected to the imaging unit, and a power supply ( 24 ) connected to the control unit. The control unit includes a switching unit ( 18, 20 ), and an axial motion detector ( 22 ) connected to the switching unit, disconnects the power supply thereby preventing the acquisition of redundant images.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
97 words
A device for acquiring in vivo images of the gastro-intestinal tract, said images forming a sequence of electronic scenes, said device comprising: at least one imaging unit; a control unit connected to said at least one imaging unit, said control unit comprising: a switching unit; and an axial motion detector connected to said switching unit; and a power supply connected to said control unit; wherein said axial motion detector detects the axial movement of the device and if the axial acceleration is below a pre-determined threshold, disconnects said power supply thereby preventing the acquisition of redundant images.
Claim 2
Independent Claim
97 words
A device for acquiring in vivo images of the gastro-intestinal tract, said images forming a sequence of electronic scenes, said device comprising: at least one imaging unit; a control unit connected to said at least one imaging unit, said control unit comprising: a switching unit; and an axial motion detector connected to said switching unit; and a power supply connected to said control unit; wherein said axial motion detector detects the axial movement of the device and if the axial acceleration is below a pre-determined threshold, disconnects said power supply thereby preventing the acquisition of redundant images.
Claim 3
Dependent Claim
38 words
A device according to claim 1 wherein said axial motion detector comprises: an accelerometer; an amplifier connected to said accelerometer, for amplifying said signal from said accelerometer; an analyzer connected to said amplifier, for analyzing said amplified signal.
Claim 4
Dependent Claim
21 words
A device according to claim 2 wherein said analyzer comprises a comparator for comparing said analyzed signal with said pre-determined threshold.
Claim 5
Independent Claim
50 words
A method for reducing redundant image acquisition of the internal gastro-intestinal tract by an imaging unit residing within a capsule within said tract, the method comprising the steps of: detecting the axial motion of said capsule; and if said detected motion is below a pre-determined threshold, disconnecting said imaging unit.
Claim 6
Independent Claim
50 words
A method for reducing redundant image acquisition of the internal gastro-intestinal tract by an imaging unit residing within a capsule within said tract, the method comprising the steps of: detecting the axial motion of said capsule; and if said detected motion is below a pre-determined threshold, disconnecting said imaging unit.
Claim 7
Dependent Claim
24 words
A method according to claim 4 further comprising the step of reconnecting said imaging unit if said detected motion is above said pre-determined threshold.
