Abstract

A device and system enables obtaining data such as in vivo images from within body lumens or cavities, such as images of the gastrointestinal (GI) tract. A device may include an imaging system and a radio frequency (RF) transmitter for transmitting signals from an imaging device to a receiving system. The signal strength of the transmitter may be varied or changed to account for, for example, the amount of signal attenuation resulting from body tissues.

Claims

1. A swallowable capsule for in vivo sensing comprising:

a transmitter; and

a RF receiver;

wherein said transmitter is capable of changing a transmission power level based on a signal received from said RF receivers.

2. The device according to claim 1 wherein the swallowable capsule comprises an image sensor.

3. The device according to claim 1 wherein the transmitter transmits image data.

4. The device according to claim 1 wherein the transmitter transmits using PSK.

5. The device according to claim 1 wherein the RF receiver is capable of receiving a power level signal from an external power level transmitter.

6. The device according to claim 1 wherein the RF receiver is to receive a command from a predetermined set of commands.

7. The device according to claim 1 comprising a processor for adjusting a power level of transmission of said signal transmitter.

8. The device according to claim 7 wherein the processor is to process power level data received from an external power level transmitter.

9. The device according to claim 1 comprising an imager.

10. The device according to claim 1 wherein the transmitter is capable of changing a transmission level based on a signal from the power level receiver.
