Abstract: A method of operating a touch screen to activate one of a plurality of virtual keys is provided. A touch location is determined based on location data pertaining to touch input on the touch screen, wherein the touch input is intended to activate one of the plurality of virtual keys. Each of the plurality of virtual keys has a set of at least one key location corresponding to it. For each of the virtual keys, a parameter (such as physical distance) is determined for that virtual key that relates the touch location and the set of at least one key location corresponding to that virtual key. The determined parameters are processed to determine one of the virtual keys. For example, the determined one virtual key may be the virtual key with a key location (or more than one key location, on average) being closest to the touch location. A signal is generated indicating activation of the determined one of the virtual keys.

Abstract: A capacitive touch sensitive position sensor is provided which has a substrate defining a touch sensitive platform. First and second resistive bus-bars arranged spaced apart on the substrate. A conductive sensing area is formed between the bus bars and is constructed with first and second conductive elements connected to the first and second resistive bus-bars respectively, and spaced apart from each other by non-conducting gaps, so that currents induced in the conductive sensing area flow towards the bus-bars, but are prevented from flowing in a direction parallel to the bus-bars. This design removes pin-cushion distortion and enhances linearization of the output signals. Because the sensing region is not galvanically coupled from one bus bar to the other, the voltage gradients remain uniform and undistorted. Capacitive coupling from one side to the other does not produce a distortion component provided that the capacitance is allowed to fully charge and discharge across all locations in the sensing region.

Abstract: The present invention is related to a method for measuring pressure resistance of a touch panel. A reference resistor Rr is added to a measurement terminal which is coupled with a X-axis of a glass substrate of the touch panel. When users touch the touch panel, the touch point is where the glass substrate (X-axis) is electrically in contact with the outer layer (Y-axis). Because current I flowing through the reference resistor Rr and a touch point resistance Rt are equal; a voltage Va across the reference resistor Rr and a voltage Vb across the touch point resistance Rt are given, it is easy to calculate resistance of the touch point. The method of the present invention can be implemented by firmware so that it is fast, simple and accurate to calibrate the touch screen of the touch panel.

Abstract: In an information management system for handling digital position data recorded by an electronic pen, the pen is controlled to convert recordings of a first code on a product to position data in a coordinate system, to convert recordings of a second code to input data, and to process the position data on the basis of the input data. The input data may define one or more functional areas in the coordinate system, and the pen may map the position data against the input data and take appropriate action if the position data is deemed to fall within a functional area.

Encryption or usage may also be controlled based on data encoded by the second code. The product may be generated, via a computer-implemented method, to include the first code, the second code and any supporting graphics.

Abstract: A method for the computation of a subdivision surface from a base mesh of coarse faces which requires no dynamic allocations is performed as follows. First, a static data structure is allocated. The static data structure includes a hierarchy of data arrays, where each of the data arrays is for storing control mesh data for a single coarse face at a respective subdivision level. The size of each of the data arrays is determined by the respective subdivision level. A subdivision algorithm is then applied to each of the base mesh coarse faces in turn. During the subdivision of a single coarse face, the resulting data for each subdivision level is stored in the respective data array. The static data structure may store further data for each subdivision level respectively, such as a tag for each of the sub-faces at the given level. The subdivision may be applied adaptively, by applying level-of-detail control information at intermediate subdivision levels.

Abstract: The effective illumination volume (e.g., angular spread and falloff) of each light source in an object model scene can be represented by a simple geometry. Geometry-based culling techniques then can be used to automatically remove or de-activate lights for a frame, set of frames, or entire shot of animation, based on interactions of the light geometries with objects in the scene. The light pruning process can be run in a pre-pass procedure, such that production and rendering preparation procedures do not have to deal with lights that will not affect the final image. Further, a pre-pass pruning removes lights before rendering, such that the data for each light does not have to be loaded into memory at render time. Removing the lights before rendering also can reduce the amount of ray tracing and other processing used for the lights at render time.

Abstract: A display device may reduce the latency of the display of a digital signal by reducing the latency that the display device adds to the digital signal. After a digital signal is received by an input module, the signal is stored in a frame buffer as a plurality of pixels. A controller determines the input frame rate of the digital signal and a pixel delay.

After the frame buffer contains enough pixels, the controller initiates transmission of the pixels from the frame buffer to a display module. In certain embodiments, the controller initiates transmission of the pixels to the display module before the frame buffer has stored all pixels corresponding to the frame.

Abstract: Mip-map construction is provided for three-dimensional rendering from an anisotropic dataset. One or more mip-map levels are generated by down sampling in the world space rather than texture space. The down sampling may be by an arbitrary scale factor rather than a power of two. For example, the voxels may be down sampled along one dimension by less than half (e.g., 16 to 12). The scale factors may be different along different dimensions. This non-uniform reduction in voxels may result in the mip-map being more isotropic than the anisotropic dataset.
