Abstract: Provided is an endoscope system including an elongated tube with one or more channels extending in a longitudinal direction along the elongated tube. The channels allow inserting of a viewing device for obtaining images from the distal end, inserting of surgical instruments to operate at the distal end, or passing of materials such as air or water. The channel for inserting the viewing device is enclosed or has a cover at the distal end of the elongated tube, such that the viewing device has no direct contact of body tissues, thereby eliminating the need for sterilization. Also provided is a safe and economical method for conducting endoscopy involving one-time use of a tube to keep the viewing device from directly contacting the body tissues.

Abstract: An endoscope system is provided. The endoscope system includes an insert tube and a handle. The insert tube includes a first connector, a first controller, a first parameter and an insert-tube data. The first parameter and the insert-tube data are corresponding to each other. The handle includes a second connector and a second controller. The second connector electronically connects to the first connector, and the second controller receives and accords to the first parameter to generate at least one first control signal to the first controller to control the insert tube.

Abstract: An insert tube and an endoscope using the same are provided. The insert tube comprises a catheter. The catheter comprises a distal section, a bending section and a extend section, and the distal section. The bending section and the extend section are integrally formed through a metal material. A plurality of a first line groove and a plurality of second line groove are formed and arranged in staggered relation on two corresponding sides of the bending section along the central axis direction of the catheter, respectively. At least one the second line groove is arranged between the first line grooves. The first line groove and the second line groove have a first arc length and a second arc length, respectively. A length of the first arc length is greater than a length of the second arc length.

Abstract: An image processing system includes an image sensor receiving light beams to output an output signal corresponding to a horizontal scan period and an image processor electronically connecting to the image sensor and including a signal interceptor and a calculating unit. The image processor transforms the output signal to generate a combining signal. The signal interceptor intercepts a first part of the combining signal corresponding to a first clock period of the horizontal scan period to obtain a first signal and intercepts a second part of the combining signal corresponding to a second clock period of the horizontal scan period to obtain a second signal. The calculating unit calculates the first signal and the second signal to obtain an image pixel data according to a differential calculation. The number of clocks of the first clock period is the same as the number of clocks of the second clock period.

Abstract: A structure of an image-sensing module includes: a top cover; a bottom cover; a set of optical lenses module; at least an elastic pressing strap; an image-sensing transistor; and a soft-tppe circuit board in combination with the image-sensing transistor in transmitting electrical signals, wherein the top cover is provided with a through hole for the engagement with the optical lenses module, and the mounting face between the top cover and the bottom cover is provided with a protruded and depressed bodies for locking with each other, such that the top and the bottom covers can be sealed or detached, and within the interior of the top cover and the bottom cover, the image-sensing transistor, the elastic pressing straps and the soft-type circuit board connected to the image-sensing transistor are stacked with one another, such that the top cover, by means of a lower pressing-strap, causes the soft-type circuit board stacked and connected with the image-sensing transistor portion to mutually press against each ot

Abstract: The present invention relates to a method of word screen formation by laser light projection and the structure of word formation by laser light projection, and in particular, relates to a plurality of laser production devices arranged in a single column and by rapid reciprocating action of the devices to project multiple columns of light track and form word arrays.

Abstract: A camera with laser view framing function includes a housing that is provided with a laser generated near a lens of the camera. The laser generator has a beam emitting hole that is oriented substantially the same direction as the lens. The housing is formed with a window on a wall that corresponds to the beam emitting hole. A shade having a frame profile through hole is insertably provided in the window. A switch key for actuating the laser generating is projectingly provided on the housing. When the switch key is pressed, the laser generator is actuated to emit a laser beam, which passes through the frame profile through hole of the shade to form a profile light frame framing an area of which a user is taking a picture.

Abstract: A palm size laser indicator disk capable of adjusting the shapes of light emitted therefrom includes an adjustment ring, a disk cover, a disk, an annular lens, a laser generating component, and a plurality of connecting screws. By turning the adjustment ring, one of a plurality of patterns of high transparency and different shapes may be caused to be penetrated by the laser light to generate different light shapes.

Abstract: Disclosed is an improved eyeglass frame having two upper half-rims of arc-shaped metal wires and two lower half-rims of high-tension strings to encircle and hold associated lenses. Each arc-shaped metal wire has hooks formed on its opposite ends, and each high-tension string has loops formed on its opposite ends to be caught by the hooks of the arc-shaped metal wire. The arc-shaped metal wire is relatively thick, and it is partly exposed from the circumferential groove of the lens, thereby permitting the bridge and temple to be soldered directly to the exposed portions of the metal wire. This arrangement has the effects of significant reduction of manufacturing cost and giving a neat appearance to the frame.

Abstract: A laser angle adjustment device for laser measuring instruments including a rectangular casing, a fixed bubble level and an adjustable bubble level mounted on the casing at right angles, a barrel turned in a hole in the casing, a top cover fixedly fastened to the barrel at one end to hold a laser module for providing a laser reference line for measurement.
