Energy management of a video capsule
First Claim
1. 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.

Abstract
An energy saving device for acquiring in vivo images of the gastro-intestinal tract is provided. The device, such as an autonomous capsule, includes at least one imaging unit; a control unit connected to the imaging unit and a power supply connected to the control unit. The control unit includes a switching unit and an axial motion detector connected to the switching unit. The axial motion detector detects the axial movement of the device and if the axial acceleration is below a pre-determined threshold, disconnects the power supply thereby preventing the acquisition of redundant images.
