The rotary joint device includes a first rotary member, a second rotary member, and a positioning device. The first rotary member includes a first positioning recess space and a second positioning recess space. The second rotary member is pivotally engaged to the first rotary member and includes a hole. The positioning device includes a body, a resilient, and a positioning part. The body includes an accommodating space. The resilient is accommodated in the accommodating space and is connected to the body and the positioning part respectively. The body is disposed in the hole and is connected to the second rotary member. The positioning part is urged against the first rotary member and is accommodated in the first positioning recess space or the second positioning recess space.12-10-2009
20100194711Optical Touch Sensing Apparatus - The invention discloses an optical touch sensing apparatus applied to a panel. The optical touch sensing apparatus comprises an frame, a first image capturing module, a second image capturing module, and a processing module. The first image capturing module is set at a first position for capturing a first image corresponding to a touch point on the panel; the second image capturing module is set at a second position for capturing a second image corresponding to the touch point. The processing module is used for determining a coordinate of the touch point according to the first image and the second image.08-05-2010
20100253634OPTICAL TOUCH DEVICE AND KEYBOARD THEREOF - The invention provides an optical touch device, including a main body, a keyboard and a light emitting member. The keyboard, placed on the main body and having a first end portion and a second end portion, includes a supporting frame, a keycap and a stopping member. The keycap is connected to the supporting frame and moves between a first position and a second position. The stopping member is connected to the keycap and moves simultaneously with the keycap. The light emitting member generates a light beam to the keyboard. When the keycap is in the first position, the light beam passes through the first end portion to the second end portion, and when the keycap is in the second position, the light beam is terminated by the stopping member, such that the light does not reach the second end portion.10-07-2010
20100309144OPTICAL TOUCH MODULE - An optical touch panel includes a frame, a first and a second image capture units, a first and second light sources, a first reflective element and a block element. The first and second image capture units are disposed on the frame and respectively disposed adjacent to the first and second light sources. The line between the first and second light sources defines a first connecting line. The reflective element disposed on a first side of the frame has a top point. The line between the top point and the second image capture unit defines a second connecting line. The block element blocks the first connecting line, but does not block the second connecting line.12-09-2010

20090234975Sliding and rotate-to-open hinge structure of a portable electronic device - This invention presents a sliding and rotate-to-open hinge structure of a portable electronic device which has an upper cover and a base. The hinge structure is provided to pivotally connect the upper cover and the base such that the upper cover could be slid and rotated relative to the base.09-17-2009
20100054721Document snapshot device - A document snapshot device is provided. The document snapshot device comprises a baseboard, a camera and a foldable supporting means. The baseboard comprises a central area to place a document and a connecting chamfer. The camera comprises a pivot. The foldable supporting means comprises a first supporting means connecting the connecting chamfers, a second supporting means connecting the pivot of the camera and a third supporting means connecting the first and the second supporting means. The first, second and third supporting means can stretch along a first plane to form a first angle between the first and the third supporting means and a second angle between the second and the third supporting means. The camera can rotate along a second plane with the pivot to form a third angle relative to a stretching direction from the second supporting means to the camera to aim at the document to take a snapshot.03-04-2010
20100175498ADJUSTMENT MECHANISM - An adjustment mechanism is provided and includes a main body having a first ratchet portion, a slider movably connected to the main body, a button having a second ratchet portion, and an elastic member connecting the slider and the button. When the elastic member exerts a spring force on the button with the first and second ratchet portions engaged with each other, the slider is movable relative to the main body only in a first direction. When the button is pressed along a second direction, the second ratchet portion disengages from the first ratchet portion, so that the slider is movable relative to the main body in the first direction or in the other direction opposite to the first direction.07-15-2010
20100177052TOUCH SCREEN - The present application provides a touch screen including a panel module, an image sensor module, and a bezel surrounding the panel module.
