A near-eye display includes an image generator that generates angularly related beams over a range of angles for forming a virtual image and a waveguide that propagates the angularly related beams over a limited range of angles. An input aperture of the waveguide includes a plurality of controllable components that are selectively operable as diffractive optics for injecting subsets of the angularly related beams into the waveguide. An output aperture of the waveguide includes a plurality of controllable components that selectively operable as diffractive optics for ejecting corresponding subsets of the angularly related beams out of the waveguide toward an eyebox. A controller synchronizes operation of the controllable components of the output aperture with the propagation of different subsets of angularly related beams along the waveguide for ejecting the subsets of angularly related beams out of the waveguide for presenting the virtual image within the eyebox.

An electronic quick change cartridge for a welding helmet. The cartridge base is formed of an optically dense polycarbonate or like material that acts as a passive filter to provide eye protection during the welding process. A port in the base receives a variable density LCD cell and a cavity formed in the base receives the electronics for driving the cell. Optical masks prevent light leakage through any interfaces of the structure. When low light levels are present, the welder views a work piece through an essentially transparent or slightly opaque LCD cell. When an arc is struck, the LCD cell darkens to a shade corresponding to the shade of the surrounding polycarbonate material. The welder then can view the work piece through the LCD cell and all the optically unobstructed portions of the polycarbonate base surrounding the LCD cell thereby to have an expanded viewing area during the actual welding operation.

A method for displaying an electronic program guide (EPG) to a viewer. The method includes displaying one or more data slices representative of broadcast programming to a viewer. In response to input from the viewer, the displayed number of data slices is increased, for example, from one slice to two slices. In browser mode the viewer can scroll through multiple EPG data slices without selecting to view full mode EPG, while in full mode the EPG can expand from a single column of data slices to multiple columns of data slices based upon viewer selections. The EPGs of the present invention can display programming that a viewer is more likely to watch at a particular time than other programming. A data slice representing the predicted programming can be inserted into the EPG so that the viewer can identify programming that is likely to be of interest.

The invention relates to a light guide plate and a lateral incident type backlight module. The light guide plate is provided with a light receiving surface which is opposite to a light source and positioned on at least one side of the light guide plate, and a light emergent surface adjacent to the light receiving surface, wherein the light receiving surface is provided with a plurality of horizontal grooves or horizontal embossed strips extending along the thickness direction of the light guide plate; the plurality of horizontal grooves or horizontal embossed strips are arranged along the length direction or width direction of the light guide plate; and the light receiving surface is also provided with longitudinal grooves or longitudinal embossed strips extending along the length direction or width direction of the light guide plate. In the invention, a light beam emitted from the LED light source is incident into the light guide plate and then a divergence angle of the light beam is increased or maintained, so as to shorten a dark band on the light emergent surface of the light guide plate, and increase a visible area of a liquid crystal display; in addition, the longitudinal grooves or longitudinal embossed strips are additionally arranged, so that the structure of the light receiving surface of the light guide plate can be more complicated, and the light receiving area of the light guide plate is increased, thus further improving the rate of incidence of light rays, and the light emitting uniformity of the backlight module.

The invention provides a keyboard of terminal equipment. The keyboard comprises linear character press keys, wherein the linear character press keys are distributed on the edge or on the periphery of a display screen in a way of surrounding the display screen while taking the display screen of the terminal equipment as the center; and number characters, English letter characters and symbol set marks are formed in the linear character press keys. The embodiment of the invention also provides an input method of a mobile terminal and the mobile terminal comprising the keyboard or using the input method. According to the technical scheme provided by the invention, the occupied space of virtual press keys is reduced, so that the equipment has a greater visual region; the problem that the conventional keyboard layout is difficult to be used on small-screen equipment is solved; and when the existing sliding input method is used in a matched way at the same time, the sliding touch with other letters cannot occur during the sliding. Compared with the existing keyboard layout, the keyboard provided by the invention has the advantages that the recognition rate is improved; further, the input operation step can be reduced in the mixed text editing state of Chinese characters, numbers and letters; and the input efficiency is improved.

An object of the present invention is to provide a digital broadcast reception apparatus that allows a stable viewing even if a reception environment changes along with a movement. In the present invention, based on current position information indicating a current position detected by a current position detection section and broadcast area information stored in a broadcast area information storage section, a search-mode switching control section instructs a tuning control section to select a diversity operation mode if the current position is close to a boundary of a broadcast area, and select an independent reception operation mode if the current position is not close to the boundary of the broadcast area. In the diversity operation mode, a first system and a second system are tuned to the same physical channel, and cooperate with each other to demodulate a digital broadcast signal and a make an output through a diversity process. In the independent reception operation mode, the first system and the second system individually and independently demodulate the digital broadcast signal and make an output

A panoramic 3D image is created by using multiple projectors whose field-of-view is narrower than the screen's width. Each projector provides a different image of a common subject from a different view angle, and the different images are mosaiced onto the screen. An observer may have a limited view of the composite image depending on which projectors are within the observer's field-of-view. A viewing volume is also extended by using space beyond a far limit line dependent upon the observer's inter-pupillary distance, the width of each projector's viewing window, and the distance from the projection baseline to the screen
