User interface and rule processing for a personal communications routing system

Abstract: A user interface provides a uniform control scheme among different devices in a personal communications routing system. The system allows devices such as a personal computer, personal information communicator, pager, fax machine and base station to be operated with a standard twelve key telephone keypad controller for the purpose of accessing electronic messages such as e-mail, voice-mail, fax transmissions, etc. Handheld communicators are docked with the devices to provide wireless transmission between a base station and numerous devices in a multi-user environment. The base station receives electronic messages for the users in, e.g., an office and routes the messages to a device as the user instructs. The user is able to perform operations on the messages such as reading, responding, deleting, etc., by using the keypad. A visual indication of user designated message bins, along with icons to represent messages received, is used to special advantage by coordinating the bin layout with the arrangement of keys on the keypad. Another feature of the system is that rules can be predefined to route, screen or otherwise manipulate the messages. The rules are applied by the base station to each incoming message. Different users can have different rules such as automatic forwarding of messages, automatic paging upon receipt of a message and sorting of messages by sender's name or time of day.

Rendering for an interactive 360° light field display

Abstract: We describe a set of rendering techniques for an autostereoscopic light field display able to present interactive 3D graphics to multiple simultaneous viewers 360 degrees around the display The display consists of a high-speed video projector, a spinning mirror covered by a holographic diffuser, and FPGA circuitry to decode specially rendered DVI video signals The display uses a standard programmable graphics card to render over 5,000 images per second of interactive 3D graphics, projecting 360-degree views with 125 degree separation up to 20 updates per second We describe the system's projection geometry and its calibration process, and we present a multiple-center-of-projection rendering technique for creating perspective-correct images from arbitrary viewpoints around the display Our projection technique allows correct vertical perspective and parallax to be rendered for any height and distance when these parameters are known, and we demonstrate this effect with interactive raster graphics using a tracking system to measure the viewer's height and distance We further apply our projection technique to the display of photographed light fields with accurate horizontal and vertical parallax We conclude with a discussion of the display's visual accommodation performance and discuss techniques for displaying color imagery

Anode and battery

Abstract: The invention provides an anode capable of relaxing stress due to expansion and shrinkage of an anode active material layer associated with charge and discharge, or an anode capable of reducing structural destruction of the anode active material layer and reactivity between the anode active material layer and an electrolyte associated with charge and discharge, and a battery using it. The anode active material layer contains an element capable of forming an alloy with Li, for example, at least one from the group consisting of simple substances, alloys, and compounds of Si or Ge. An interlayer containing a material having superelasticity or shape-memory effect is provided between an anode current collector and the anode active material layer. Otherwise, the anode current collector is made of the material having superelasticity or shape-memory effect. Otherwise, a thin film layer containing the material having superelasticity or shape-memory effect is formed on the anode active material layer.

Nitride semiconductor element and production method for nitride semiconductor element

Abstract: A nitride semiconductor element excellent in characteristics even its element structure is three-dimensionally formed by a selective growth or the like, and a production method therefor. A nitride semiconductor element having an electrode layer (21) formed via a high-resistance region such as an undoped gallium nitride layer (17) on the upper layer of a crystal layer having a side surface (16s) and the upper layer (16t) and being grown three-dimensionally. A high resistance region provided to the upper layer (16t) allows current to flow so as to bypass the high resistance region of the upper layer (16t) to form a current route mainly consisting of the side surface (16s) with the upper layer (16t) bypassed. As a result, current is prevented from flowing to the upper layer (16t) having a poor crystallinity.

Display device and display method

Abstract: Disclosed is a display device capable of compensating unevenness in brightness caused by physical restrictions of a display device or degradation in image quality caused by a partial reduction in contrast occurring in the local dimming technology using human visual characteristics. A liquid crystal panel ( 101 ) modulates illuminating light in accordance with the transmittance, and displays images on a screen. A backlight ( 102 ) emits the illuminating light to the liquid crystal panel ( 101 ) such that amounts of the illuminating light differ for each light emitting area of the screen. A backlight control unit ( 106 ) controls emission brightness of the backlight ( 102 ) for each light emitting area. A local gradation converting unit ( 104 ) performs gradation conversion on an image signal, and acquires a brightness value for each pixel after the conversion. A backlight driving unit ( 107 ) controls the transmittance for each pixel on the basis of the acquired brightness values after the conversion. The local gradation converting unit sets conversion characteristics for pixels to be processed in the image signal such that the brightness values of the pixels to be processed are low as the lightness of the periphery of the pixels to be processed is high, and performs gradation conversion using the set conversion characteristics.
