  • Patent number: 9125557
    Abstract: A magnetic maneuvering system for capsule endoscope includes the capsule endoscope, an annular fitting sleeved around the outer surface of the capsule endoscope. A plurality of magnetic driven parts are provided and distributed on the annular fitting member. The control device includes a magnetic driving part for magnetically actuating the magnetic driven parts, thus enabling the capsule endoscope to rotate and move in an organism as a result of the actuation of the magnetic driven parts. By magnetically controlling the magnetic driven parts, the capsule endoscope is allowed to rotate or move under the control of the control device to achieve better image retrieval results and improve over the poor image retrieval results obtained by the prior art since the location and direction of a traditional capsule endoscope, relying solely on the contractions of the digestive tract, cannot be controlled.

  • Publication number: 20130345506
    Abstract: A magnetic-controlled system for colonoscopy is provided, including a supporting rod, an image retrieving unit, annular sheaths and a controlling device. After the supporting rod enters the large intestine of an organism via the anus, the image retrieving unit at the top end segment of the supporting rod then retrieves images of the large intestine. The annular sheaths are disposed around the supporting rod. Each of the annular sheaths has a plurality of magnetic-driven parts. The controlling device has a rotatable magnetic driving part. The magnetic-controlled system allows the rotation of the magnetic-driven parts, which in turn rotates the annular sheaths to facilitate the supporting rod moving smoothly in the large intestine, by rotating the magnetic driving parts and forward moving of the controlling device. Therefore, the pain experienced by the patients when the supporting rod is moving ungainly inside the intestine is greatly relieved.

  • Publication number: 20040030936
    Abstract: A notebook computer having a temperature adjustment function for a microprocessor includes a clock generator, a thermal sensor, an I/O controller, a bus switch, and a voltage regulator. The thermal sensor and the I/O controller are connected between the microprocessor and the clock generator. The bus switch is connected between the microprocessor and the I/O controller and with the voltage regulator. When the surface temperature of the microprocessor exceeds a predetermined temperature, the system BIOS will immediately issue a command to the I/O controller to automatically lower the external clock and the power source voltage level of the microprocessor. Thereby, the power consumption of the microprocessor can be reduced to lower the surface temperature.
