The present invention relates to a wireless capsule endoscope and a power supply control method thereof. The method includes controlling the power supply of the capsule endoscope wirelessly and automatically adjusting power consumption of the power supply in the capsule endoscope. The wireless capsule endoscope includes a capsule casing, a light generator arranged at outside of the capsule casing, an opto-electronic switching starter arranged in the capsule casing, a power supply, a control module, a posture sensor, an illumination unit, an image processing device and a radio frequency transmission unit. The power supply being driven by the light generator in the present invention can effectively solve the incompatible problem between a traditional magnetic switch and a magnetic control device. Meanwhile, the control module and the posture detector enable the power supply to be in different working status under different states, which can prolong the service life of the power supply of the capsule endoscope.

Controlling an image capturing process by tracking the positions of the capsule endoscope is described. The images are taken only when there is either new position and/or new orientation change of the capsule endoscope. The method described effectively decreases the total amount of images that a doctor needs to review, and improves the power consumption of the capsule endoscope examination process.

System and method to provide a suspended capsule endoscope at a liquid gas interface is described. The capsule comprises a permanent magnetic dipole and has a density greater than the density of the liquid. An sphere-shaped external magnet is used to suspend and control the movement of the capsule endoscope at the liquid/gas interface. The capsule endoscope can translate along variable axes, rotate and tilt, according to the movement of the external magnet. The external magnet performs a translation and rotation simultaneously to keep the capsule endoscope still and anchored at the same position of the liquid/gas interface. The external magnet adjusts its distance to the liquid/gas interface during the rotation in order to apply a constant magnetic field force to the capsule endoscope.

A self-adjusting optical add-drop multiplexer monitors the power in a drop signal and attenuates the power in an add signal to match the power in express WDM channels (signals). When used in a fiber network, and more particularly, in a metro network, the deleterious effects of optical amplification are reduced. Power attenuation is also used in an optical switching assembly particularly useful in two-fiber ring network. The optical switching assembly monitors drop channels from the two rings of the network and attenuates the add channel(s) accordingly. An optical switch operates to direct the drop signal from one of the two rings to a receiver in accordance with a control signal based on the monitored drop channels. The self-adjusting optical add-drop multiplexer also monitors the power in the drop signals and issues an alarm if the drop signal is of a power level above or below predetermined levels.

In one embodiment, sixteen wavelength are dynamically switching, routed, or distributed among five optical add/drop nodes using narrowly wavelength tunable transmitters and fixed optical add/drop multiplexer modules.
