Abstract
There is provided a capsule-type device, which is provided with a power generator that generates power by receiving at least one of a time-varying electric field and a time-varying magnetic field, and a casing that surrounds the power generator. The power generator includes a plurality of receiving elements having different directionalities with regard to the at least one of the time-varying electric field and the time-varying magnetic field.
Claims21
A capsule-type device, comprising:
- a power generator that generates power by receiving at least one of a time-varying electric field and a time-varying magnetic field;
- a casing that surrounds the power generator,
- the power generator including a plurality of receiving elements having different directionalities with regard to the at least one of the time-varying electric field and the time-varying magnetic field, the plurality of receiving elements having coils respectively located on planes having different orientations;
- an objective lens system that forms an image of an object, the coils including a coil located to cross an optical path of the objective lens system, the optical path passing through an opening of the coil;
- an image pickup device that converts the image formed thereon by the objective lens system to an image signal;
- and
- a transmitter that transmits the image signal, generated by the image pickup device, by a radio signal.

A capsule-type device controlling system, comprising:
- an outside power source that generates a time-varying magnetic field;
- and
- a capsule-type device including a power generator that generates power by receiving the time-varying magnetic field to supply the power to internal components of the capsule-type device, the power generator including a plurality of coils located on at least three side surfaces of a rectangular prism shape, the plurality of coils being respectively located on planes having different orientations;
- an objective lens system that forms an image of an object, the coils including a coil located to cross an optical path of the objective lens system, the optical path passing through an opening of the coil;
- an image pickup device that converts the image formed thereon by the objective lens system to an image signal;
- and
- a transmitter that transmits the image signal, generated by the image pickup device, by a radio signal.
