Problems solved by technology

Because antenna efficiency is proportional to its area, where the antenna efficiency is measured by the amount of RF power radiated, small physical dimensions can lead to significantly lower antenna efficiency, affecting the power budget of the overall communication channel
On the other hand, during the transmission of RF signals from the sensing device inside the patient to the external receiver / recorder, the quality of the RF signal may also be degraded due to power attenuation caused by the human body
Also, potential sources of noise in the surrounding environment where in vivo diagnostics are performed can also have a degrading effect on the signal detected by the receiver / recorder

Embodiment Construction

[0030] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. However, it will be understood by those of ordinary skill in the art that embodiments of the invention may be practiced without these specific details. In other instances, well-known methods, procedures, components and circuits have not been described in detail so as not to obscure the embodiments of the invention.

[0031] Certain embodiments of the present invention relate to a typically swallowable device that is passively or actively advanced through the gastrointestinal (GI) tract, in one example, under natural peristalsis. Other embodiments relate to in vivo sensing devices that can pass through other body lumens, such as through blood vessels, reproductive tract, and the like. The device may be a sensing device, an imager, a diagnostic device, a therapeutic device, or a combination thereof. According to...

Abstract

An in-vivo communication system comprises an in-vivo transmitting device, multiple receiving devices, a signal selector, and a signal processing device. The signal selector being able to select two or more signals from multiple received signals at the multiple receiving devices, and the signal processing device being able to combine the selected two or more signals to reproduce a transmitted signal. A method of reproducing the transmitted signal from two or more signals selected from multiple received signals.

Description

technical field [0001] The present invention generally relates to an in vivo sensing system. In particular, the present invention relates to an apparatus and method for processing signals transmitted between an in-body transmitting device and a plurality of receiving devices to obtain eg captured image signals and / or other telemetry data. Background technique [0002] In vivo sensing systems, in vivo devices, eg, swallowable devices that are movable through the gastrointestinal (GI) tract and that can collect and transmit data to a receiving system are known in the art. The in-vivo device, such as a cylindrical capsule, may have a wireless telemetry system to allow continuous transmission of the data desired to be collected, or at pre-programmed intervals via radio frequency (RF) as pulses through a miniature antenna. This radio transmission is then received by a small receiver attached to the patient or in a clinic, for example. [0003] Due to the practical size constrai...
