  • Publication number: 20040246239
    Abstract: A circuit for an acoustic wave switch or sensor having a resonant acoustic wave cavity detects a touch or sensed event using a time domain approach. The circuit includes a controller that drives an acoustic wave transducer to generate a resonant acoustic wave in the acoustic wave cavity during a first portion of a sampling cycle. In a second portion of the sampling cycle, the controller monitors the time that it takes for the acoustic wave signal from the transducer to decay to a predetermined level. Based on the decay time, the controller detects a sensed event, such as a touch on the acoustic wave switch/sensor.

  • Publication number: 20040246240
    Abstract: Systems, methods, and computer-readable media are used to determine whether specific electronic pen gestures with respect to pen-based computing systems should be processed as “press-and-hold” gestures (e.g., to activate right mouse button click actions). Such methods may include: (a) measuring two different parameters associated with pen interaction or orientation with respect to a digitizer during a pen-down event; and (b) determining whether the pen-down event constitutes a press-and-hold gesture based, at least in part, on the measured parameters. In some instances, if the systems and methods cannot immediately determine whether a press-and-hold gesture is intended, measurements may be made again (as many times as necessary or until a time-out occurs) such that the determining step can be performed one or more additional times taking into consideration the additional parameter measurement data collected since the original parameter measurements.

  • Publication number: 20040246254
    Abstract: Colors are specified within the individual glyphs of a font by means of an indirect approach which employs multiple tables. The data values for individual pixels of a glyph identify entries in an index table, which pertains to a subset of all available colors. The entries in the index table map to a complete set of colors that are specified in a color table. As a result of this structure, the amount of data that is required to specify the individual pixels of a glyph can be minimized to the number of bits required to distinguish the colors within that glyph. The specification of all available colors within a single table permits that table to be shared among various resources, including bitmap fonts and outline fonts.

    Abstract: A saturation detecting means (200) detects saturation at every pixel in a digital color image or at every coordinate point in an analog color image. A saturation conversion control means (300) determines the saturation conversion condition for the pixel or coordinate point based on the detected saturation. A saturation conversion processing means (400) implements saturation conversion in such a manner that saturation is reduced for the areas with low saturations in the color image, so as to enlarge the difference in saturation relative to the areas with high saturations, thus achieving improved saturation contrast. Further, the distribution of saturations in the input image is automatically extracted, so as to determine the threshold for deciding a saturation suppressed area based on the distribution of saturations. In this way, in order to obtain a color image improved in vividness and presenting feeling of sharpness, the saturation contrast is automatically improved.

    Abstract: A visual display unit connected to a central processing unit such as exhibited with a personal computer. A sensor which measures the distance between the user and the visual display unit is provided. The purpose of the sensor enables the computer to determine the distance of the user in relation to the visual display unit, such that the size and content of information displayed upon the visual display unit can be automatically adjusted. As the user moves away from the visual display unit, the central processing unit causes the image shown on the visual display unit to enlarge any displayed information, thus counteracting the effects of perspective, which makes objects appear smaller the further away they are from the viewer. An alternative embodiment replaces the sensor with a web camera and a still image capture apparatus to measure the distance from the user to the visual display unit by utilizing at least two reference points on the user to make a “range finder” calculation.

    Abstract: The grayscale levels of red, green and blue display data are detected in each sub-frame, and the intensity of incident light on a liquid crystal panel and the transmittance of the liquid crystal panel are adjusted based on the detection result. The transmittance of the liquid crystal panel is adjusted to have maximum transmittance for display data that requires a maximum amount of transmitted light in each of red, green and blue sub-frames, and the intensity of incident light is reduced according to the adjustment result of the transmittance. By reducing the amount of incident light on the display element to the minimum required amount, the power consumed by a back-light is reduced as much as possible while maintaining the display images of the respective colors according to the grayscale levels.

    Abstract: Driving condition is determined so that the stimulating values of brightness with respect to drive data become closer to being regular in interval. As the drive condition, the frequency of a reference clock used for the pulse width modulation is changed to be higher than the range of high gradations in the range of low gradations in drive data. Accordingly, smaller increment in brightness in the range of low gradation and larger increment in the range of high gradations are achieved.

  • Publication number: 20040246283
    Abstract: A fluid reservoir sensing system includes a pair of optical prisms that reflect light when a fluid level is below one of the pair of prisms. The pair of optical prisms includes a low prism usable to sense a low liquid level in the fluid reservoir, and a high prism usable to sense a high liquid level in the fluid reservoir. The fluid reservoir sensing system optionally includes an emitter and a photosensor. The emitter projects light through at least one of the low prism to the low incident surface and the high prism to the high incident surface. The photosensor senses light reflected from the low prism while the liquid is below the low prism. The photosensor also senses light from the high prism while the liquid level is below the high prism.

  • Publication number: 20040246286
    Abstract: An automatic printer 1 prints a portion of a pattern onto an allocated region of a print medium 3, picks up the image of this printed pattern using an image pickup device 6, and after the image pickup, forwards the printed region portion to position a next allocated region in an effective printing region 16. Then, the automatic printer 1 again picks up the image of the above-described printed pattern using the image pickup device 6, and compares these two images. When these images deviate from each other, the automatic printer 1 makes a correction, and performs printing in a state where the joint position of the pattern precedently printed and that of a pattern to be next printed conformed to each other.
