20110134434 | METHOD AND SYSTEM FOR POSITIONING BY USING OPTICAL SPECKLE - A method and system for positioning by using optical speckle are disclosed in this invention. A highly coherent laser light irradiates a positioning template in advance to record optical speckles caused by interference by scattered light beams from the positioning template for establishing a speckle database. Furthermore, a reference point is defined to position each recorded speckle. Therefore, a coordinate with respect to the reference point corresponding to a specified speckle can be used to position a target or applied to distance measurement by the speckle database. The precision of the speckles according to the present invention is within several micrometers. Hence, it can provide high precision positioning. | 06-09-2011 |
20110141014 | MOVABLE TOUCHPAD WITH HIGH SENSITIVITY - A highly sensitive movable touchpad is disclosed in the present invention. It is used for laptop computers and has a slidable template for users to move so that a cursor can be controlled by the touchpad. A resistive or capacitive detecting surface can be applied for detecting users' click, double click, drag, or scroll motion on any point of the surface. Additionally, there is an optical displacement sensor provided under the slidable template for detecting surface information on the back surface of the slidable template. A sequence of images of surface movement are processed by an image processing unit. Then, relative movement information is calculated and sent to an operating system in the computer. The operating system controls the cursor with the relative movement information. The present invention uses edge detectors for dynamically controlling the cursor and calibrating location of the cursor so that positioning of the touchpad is synchronous with the cursor. | 06-16-2011 |
20120170259 | FLAT TUBULARLAMP - A flat fluorescent lamp which includes: a long rectangular shaped light guiding panel, a light-emitting module, a light guiding body, a reflective layer, and at least one light-emitting diode. The light guiding body seamlessly connects between an end surface of the light guiding panel and the light-emitting module. The reflective layer is located exterior of the light guiding panel. A Coupling head is installed on the side of the light-emitting module that is away from the light guiding panel, and the coupling head is connected to the light-emitting module. Thereby, an energy efficient fluorescent lamp that can be thinner and installed on general lamp socket is provided. | 07-05-2012 |
20120236597 | LAMP AND FRAME MODULE THEREOF - A frame module includes a frame strip, a light emitting diode (LED) bar, and a fastener. The frame strip has a heat-dissipating portion, two elastic arms extended in one direction from the two edges of the heat-dissipating portion, and two pressing portions inwardly protruded form the two elastic arms. The heat-dissipating portion, the two elastic arms, and the two pressing portions define an accommodating trough. The LED bar has a printed circuit board (PCB) and a plurality of LEDs mounted on the PCB. The PCB is arranged in the accommodating trough of the frame strip and clamped between the heat-dissipating portion and the two pressing portions. The fastener is fixed on the two elastic arms. Thus, the heat generated form the LED bar is conducted by the LED bar directly contacting the frame strip. Besides, the instant disclosure also provides a lamp. | 09-20-2012 |
20120320591 | LIGHT BULB - The instant disclosure relates to a light bulb, which includes a base, a conducting cap arranged on one end of the base, a heat-dissipating member disposed on the opposite end of the base, and a lamp cover. The heat-dissipating member has a wedged structure, and a plurality of inclined surfaces are formed adjacently thereon. A plurality of LEDs is disposed on the inclined surfaces, and the lamp cover is arranged over the wedged structure and the LEDs. The instant disclosure uses the LEDs to replace tungsten filament as the light sources, and arranging the LEDs on the wedged structure of the heat-dissipating member. Thereby, the light bulb can have higher heat-dissipating rate. | 12-20-2012 |

20130128608 | LED LIGHT FIXTURE - The instant disclosure relates to a LED light fixture, which includes a mounting seat, a lighting module, a light guiding assembly, a retainer, and a panel. The mounting seat has a base and an annular side wall cooperatively defining a recess. The lighting module abuts the side wall and is disposed around the light guiding assembly. The retainer abuts the light guiding assembly and retains the light guiding assembly on the mounting seat. The panel is disposed between the light guiding assembly and the base, with the periphery of the panel abutting the engaging shafts. Thereby, the interaction between the retainer and the mounting seat enables the user to assemble or dismantle the light fixture with more ease. | 05-23-2013 |
20150160043 | High-Precision Angle Positioning Device - The present invention proposes a high-precision angle positioning device. To complete a high-precision angle positioning operation, the high-precision angle positioning device firstly uses a non-deformable laser-speckles image-acquiring unit to acquire N non-deformable laser-speckles images from a rotary disk unit, and then defines N coordinated non-deformable laser-speckles images and N coordinated angles through an angle calibrating unit and an angle recognizing and positioning unit; therefore, after finding an i-th coordinated non-deformable laser-speckles image having the largest overlapping area with an immediate non-deformable laser-speckles image through image comparison, an immediate image plane displacement between the immediate non-deformable laser-speckles image and the i-th coordinated non-deformable laser-speckles image can be calculated for calculating immediate sub-coordinated angle of immediate non-deformable laser-speckles image, such that an immediate angle coordinate for the immediate non-deformable laser-speckles image can be calculated through an i-th coordinated angle of the i-th coordinated non-deformable laser-speckles image and the immediate sub-coordinated angle. | 06-11-2015 |
