20150124228 | IMAGE PROJECTION APPARATUS AND IMAGE PROJECTION METHOD - An image projection apparatus and an image projection method are provided. The image projection apparatus includes a projection light source, a scanning module, a reflection mirror and an optical detector. The projection light source provides a projection light beam and the scanning module drives the projection light beam to scan along at least an axial direction. The reflection mirror is located on a scan path of the projection light beam. The optical detector detects the projection light beam reflected by the reflection mirror and generates synchronous signals. The image projection apparatus determines a scanning frequency of the projection light beam according to the synchronous signals. | 05-07-2015 |

20150215591 | Scanning Projection System - A scanning projection system includes a scanning mirror module, a controlling circuit, and a laser module. A swinging motion of the scanning mirror module is controlled according to a driving signal, and a combined laser beam reflected by the scanning mirror module is swept across a projection surface to produce plural projection points on a projection surface. The controlling circuit includes a weight mapping unit for converting an image signal into a compensated image signal according to a position-and-weight mapping relationship. The laser module generates the combined laser beam according to the compensated image signal. After plural weights of the corresponding projection points are acquired according to positions of the corresponding projection points and the position-and-weight mapping relationship, the weight mapping unit multiplies the image signal by the corresponding weights according to the positions of the projection points. Consequently, the compensated image signal is generated. | 07-30-2015 |

20140050882 | SCREEN PROTECTION DEVICE FOR HAND-HELD ELECTRONIC APPARATUS - A screen protection device includes: a tempered glass sheet comprising a first surface and a second surface; a non-transparent layer positioned on the first surface and defining a transparent area for the screen protection device; and a sticking layer positioned on at least a portion of the non-transparent layer and surrounding the transparent area. An air layer is formed between a display screen of a hand-held electronic device and the transparent area, and one or more bidirectional air tunnels are formed between the sticking layer and the upper surface. When the transparent area is pressed to approach to or to contact with the display screen, air flows from the air layer to an outside space via the one or more air tunnels. Afterward, air flows from the outside space to the air layer via the one or more air tunnels when the transparent area is not pressed. | 02-20-2014 |

20140070007 | Barcode Reading Method and Barcode Reading Device - A barcode reading method and a barcode reading device are provided. An image sensor is utilized to capture an image of a barcode via an optical lens, and then a triangulation method and an ideal lens imagining method are collocated to calculate the digital image so as to produce an optimum image distance. A distance between the image sensor and the optical lens is then adjusted in accordance with the optimum image distance, so that the barcode can be immediately and clearly imaged on the image sensor. | 03-13-2014 |
