20120194086 | LIGHT EMITTING DIODE TUBE AND LIGHT EMITTING DIODE LAMP USING THE SAME - A light emitting diode (LED) tube and an LED lamp using the same are provided. The LED tube is suitable for direct installation in a lamp holder which has a starter and a ballast. The LED tube includes an LED array, an LED driver, and a rectification-block diplexer. When the LED array is driven by the LED driver, the rectifier-block diplexer disables the starter and the ballast and at the same time receives and converts an AC power supply. Thus the rectifier-block diplexer provides an operating voltage to the LED driver. Without removing the starter and shorting the ballast, the user can easily install the LED tube into a traditional fluorescent lamp socket, saving the cost of lamp modification, thus achieving the purpose of energy saving and environmental protection. | 08-02-2012 |
20130148175 | SCANNING DEVICE - A scanning device includes a body, a paper-feeding module, a scanning module and two transmission modules. The body has a paper-feeding area and a scanning area stacked with each other. The paper-feeding module is disposed at the paper-feeding area in the body and the scanning module is disposed at the scanning area in the body. One of the transmission modules is disposed within the paper-feeding area and electrically connected to the paper-feeding module so as to convey a document from the paper-feeding area to the scanning area, while another of the transmission modules is disposed within the scanning area and electrically connected to the scanning module so as to drive the scanning module for scanning images on the document. | 06-13-2013 |
20150035438 | OVER-TEMPERATURE PROTECTING APPARATUS AND OVER-TEMPERATURE PROTECTING METHOD THEREOF - An over-temperature protecting apparatus and an over-temperature protecting method thereof are provided. The method includes following steps: detecting the temperature of the over-temperature protecting apparatus to obtain an adjusting signal and outputting the adjusting signal to a current detection pin of the control chip; adjusting the duty-ratio of the pulse-width modulated signal by the control chip output from the gate output pin according to the adjusting signal received by the current detection pin. | 02-05-2015 |
20150054918 | THREE-DIMENSIONAL SCANNER - A three-dimensional (3D) scanner including a light-source module, a screen, a rotary platform, an image capturing unit and a process unit is provided. The light source module is configured to emit a beam. The screen disposed on a transmission path of the beam has a projection surface facing the light source module. The rotary platform carrying a 3D object is disposed between the light source module and the screen. The 3D object is rotated to a plurality of object orientations about a rotating axis to form a plurality of object shadows on the projection surface. The image capturing unit is configured to capture the object shadows from the projection surface to obtain a plurality of object contour images. The process unit is configured to read and process the object contour images to build the digital 3D model related to the 3D object according to the object contour images. | 02-26-2015 |
20150056318 | PRINTING HEAD MODULE AND THREE DIMENSIONAL PRINTING APPARATUS USING THE SAME - A printing head module and a three dimensional (3-D) printing apparatus using the same are provided. The 3-D printing apparatus includes a base and the printing head module. The printing head module is disposed above the base and includes a printing head and at least one material spool. The printing head includes a plurality of assembling pieces assembled with each other to form the printing head and define a nozzle of the printing head. Each of the assembling pieces includes at least one material-supply groove. The material-supply grooves of any two adjacent assembling pieces are located corresponding to each other to form at least one material-supply channel together. Each material spool is connected to the material-supply channel for providing at least one fluid material to the material-supply channel. The fluid material is transmitted via the material-supply channel to be dispensed on the base. | 02-26-2015 |
20150057781 | THREE DIMENSIONAL PRINTER AND METHOD FOR ADJUSTING WORKING COORDINATE OF PLATFORM THEREOF - A three-dimensional (3-D) printer and a method for adjusting a working coordinate of a platform thereof are provided. The 3-D printer includes a platform, a printing head and a control unit. The platform includes a carrying surface and adjustment points located on the carrying surface. The printing head disposed above the platform for moving along a datum plane and a normal direction of the datum plane. The control unit controls the printing head to move from the datum plane toward the platform to contact each of the adjustment points for obtaining a coordinate offset of the carrying surface corresponding to the datum plane, and adjusts a model coordinate of a digital 3-D model information according to the coordinate offset. The control unit moves the printing head according to the adjusted model coordinate to print a 3-D object related to the digital 3-D model information on the carrying surface. | 02-26-2015 |
20150251358 | THREE DIMENSIONAL PRINTING APPARATUS AND METHOD FOR CONTROLLING PRINTING HEAD THEREOF - A three-dimensional printing apparatus and a method for controlling printing head thereof are provided. The method is used for controlling a moving path of a printing head of the three-dimensional printing apparatus and the method includes following steps. The printing head is controlled to form a layer object on a carrying surface according to three-dimensional model information. It is determined whether a cross-section parameter of the layer object is match to a small range condition. If the cross-section parameter of the layer object is match to the small range condition, the printing head is controlled to move toward a first direction far away from layer object according to position information of the layer object. The printing head is controlled to move toward a second direction close to the layer object. | 09-10-2015 |
20160041977 | STORING METHOD FOR EDITED IMAGE FILE - A storing method temporarily records every editing actions when a 3D-model of an original image file is edited. When the 3D-model is edited completely and an edition-completed model is obtained, a project file is created to store an absolute address of the original image file located in a hard-drive, and to store the temporary recorded editing actions to as a log file of the project file. When the project file is opened later, it opens the 3D-model of the original image file in according to the stored absolute address, and then the opened 3D-model is edited automatically in according to the stored editing actions. Therefore, the edition-completed model can be obtained directly whenever the project file is opened. Also, a user can recover the edition-completed model back to a status before executing any one of the edition actions in according to the log file. | 02-11-2016 |
