ACTIVATION OF IMAGING CAPSULES WITH ALTERNATING CURRENT
First Claim
1. An imaging capsule activating system, comprising:
- an imaging capsule containinga radiation source,an arrangement with the radiation source mounted thereon, wherein the arrangement is configured to selectively allow emission of radiation from the radiation source,a blocking arrangement configured to selectively block emission of radian from the radiation source, wherein in a rest position the emission of radiation from the arrangement is blocked,a movement arrangement configured to move the blocking arrangement relative to the arrangement,a controller configured to operate the radiation source and the blocking arrangement, andan activation coil electrically coupled with the controller, the activation coil having an initial configuration without current flow; and
an external activating coil, the external activating coil being configured to receive the imaging capsule, the external activating coil being operable to inductively induce current flow in the activation coil within the capsule.

Abstract
An imaging capsule activating system includes a capsule containing a radiation source and an arrangement with the radiation source mounted thereon. The arrangement is configured to selectively allow emission of radiation from the radiation source. A blocking arrangement is configured to selectively block emission of radian from the radiation source. In a rest position, the emission of radiation from the arrangement is blocked. A movement arrangement configured to move the blocking arrangement relative to the arrangement. A controller operates the radiation source and the blocking arrangement. An activation coil is electrically coupled with the controller and has an initial configuration without current flow. An external activating coil receives the imaging capsule and is operable to inductively induce current flow in the activation coil within the capsule.

3. An imaging capsule activating system, comprising:
-
an imaging capsule containing a radiation source, a rotatable disk with the radiation source mounted on the disk and wherein the rotatable disk is configured to allow emission of radiation from the radiation source substantially only from a few locations on the circumference of the disk, an outer ring surrounding the circumference of the disk and configured to rotate relative to the disk, the outer ring including areas that block radiation and areas that are transparent to the emission of radiation, wherein in a rest position the outer ring is situated relative to the rotatable disk such that the areas that block radiation are blocking the emission of radiation from the few locations on the circumference of the disk that allow the emission of radiation, a rotation arrangement configured to rotate the rotatable disk relative to the outer ring, a controller configured to operate the radiation source and the rotation arrangement, and an activation coil electrically coupled with the controller, the activation coil having an initial configuration without current flow; and an external activating coil, the external activating coil being configured to receive the imaging capsule, the external activating coil being operable to inductively induce current flow in the activation coil within the capsule.
