DEVICE, METHOD AND SYSTEM FOR IN-VIVO SENSING
FIELD OF THE INVENTION
 The present invention relates to the field of in-vivo sensing. More specifically, the present invention relates to devices, systems, and methods for in-vivo sensing using activity extending or delay mechanisms.
BACKGROUND OF THE INVENTION
 Devices, systems and methods for in-vivo sensing of passages or cavities within a body, and for gathering information (e.g., image information, pH information, temperature information, electrical impedance information, pressure information, etc.), are known in the art.
 An in-vivo sensing device may include, for example, an imaging device for obtaining images from inside a body cavity or lumen, such as the gastrointestinal (GI) tract. The imaging device may include, for example, an imager associated with units such as, for example, an optical system, an illumination unit, a power source, a transmitter and an antenna. Other types of in-vivo sensing devices exist, such as endoscopes which may not require a transmitter, and devices performing functions other than imaging.
 Various operations performed by an in-vivo sensing device may consume energy, which may be provided by, for example, a power source within the device. Typically, reliable acquisition and transmission of images or other data may consume a significant amount of energy. There may be other "costs" or resource usages associated with reliably transmitting images, for example, a need to use various algorithms and/or processes. Other factors may limit the length of time an in-vivo sensing device may operate.

 There is a need to provide a longer period of operation to some in-vivo sensing devices. Further, in some cases, there is a need to alter the timing of the operation of in- vivo sensing.
SUMMARY OF THE INVENTION
 Various embodiments of the invention provide activity extending or delay mechanisms for in-vivo sensing. Various embodiments may alter the timing of the operation of in-vivo sensing or sensing devices.
 Some embodiments of the invention provide, for example, an in-vivo sensing device which may allow a longer, improved, and/or extended period of operation for in- vivo sensing. In other embodiments, other benefits may occur.
 In some embodiments, for example, an in-vivo sensing device may include a controller and/or a delay mechanism, which may delay and/or prolong the operation of the in-vivo sensing device and/or of components within the in-vivo sensing device (e.g., imager, power source, illumination source, transmitter, processor, or sensor). Such a controller or control capability may be internal or external to the in-vivo sensing device.
 In accordance with some embodiments, for example, an in-vivo sensing device may be inserted to a patient's body (e.g., by swallowing a...
