Abstract: A photographing system and a method of image fusion are provided. The photographing system includes a plurality of camera and a controller. The cameras are configured to photograph a scene to produce a plurality of sub-images. The controller is signal-connected with the cameras to obtain the sub-images. The controller analyzes the sub-images to obtain a plurality of objects contained in the scene. After the controller establishes a Pareto set of each object, the controller splices the objects according to the Pareto sets of the objects to generate an image after fusion of the sub-images.

Abstract: A user equipment terminal (UE) performs cell search in a wireless network. The UE determines a search pattern based on statistics of search trials performed at one or both of a location and time in a recurrent time cycle. The search pattern includes a sequence of alternating search durations and non-search durations for a configurable number of searches. Furthermore, the search pattern includes the search durations or the non-search durations that increase, decrease, or no-change according to probability derived from the statistics. The UE performs the cell search according to the search pattern.

Abstract: A method for improving circuit switched fallback for a user equipment (UE) in a wireless communications system, herein the UE is capable of communicating via first and second radio access technologies (RATS), including: determining that a connection has been released, wherein the connection is associated with a second network corresponding to the second RAT; starting a timer providing a period of time when the connection has been released; and stopping e timer after a condition is satisfied.

Abstract: A projection apparatus includes a light source emitting an illuminating beam, a light valve receiving the illuminating beam to create an image beam, and a projection lens system arranged on a path of the image beam for receiving and projecting the image beam onto a screen. The projection lens system includes four lens elements arranged along the optical axis in order from the screen toward the light valve, namely, first, second, third and fourth lens elements respectively having positive, negative, positive and positive refractive power. The four-piece projection lens system satisfies the condition of 0.79<BFL/TL<0.99; where, BFL is the back focal length of the projection lens system, and TL is the overall length of the projection lens system on the optical axis from a screen side of the first lens element to a light-valve side of the fourth lens element.

Abstract: The invention discloses an arrayed light emitting diode (LED) module including multiple LED chips and light-reflecting members. Multiple gaps exist between LED chips adjacent to each other. Each of the light-reflecting members respectively is disposed in one of the gaps. The light-reflecting member reflects the light emitted from the LED chips, to diminish the dark gap shown on the illumination region, further to uniform the brightness distribution of the illumination region.

Abstract: An LED light converging system includes an LED light source, and first and second lens units aligned in sequence along an optical axis. The LED light source provides source light. The first lens unit has a first focal length, and is disposed forwardly of and is spaced apart from the LED light source by a first distance less than the first focal length such that a virtual image of the source light provided by the LED light source is formed rearwardly of the LED light source. The second lens unit has a second focal length, is disposed forwardly of the first lens unit, and is spaced apart from the virtual image of the source light by a second distance larger than the second focal length such that a real image of the source light provided by the LED light source is formed forwardly of the second lens unit.
