Abstract: A USB device for supplying current to a device connected thereto through a USB interface. In this USB device, current values requested by the devices are preset, as detecting current values, in detector registers of current detecting parts. The current detecting parts constantly monitor current values of electric powers supplied to the devices. Each current detecting part compares a related detecting current value with a related supplied current value. If the supplied current value exceeds the detecting current value, the current detecting part informs a current detection control part of abnormality occurrence. The current detection control part sets a bit in a no-good status register, which corresponds to the current detecting part having informed the abnormality occurrence, and interrupts a CPU. In turn, the CPU refers to the no-good status register and specifies the failure device, and interrupts a current supplying path connecting to the failure device.

Abstract: A process for generating with unification based grammars such as Lexical Functional Grammars which uses construction and analysis of generation guides to determine internal facts and eliminate incomplete edges prior to constructing a generation chart. The generation guide can then be used in the construction of the generation chart to efficiently generate with unification-based grammars such as Lexical Functional Grammars. The generation guide is an instance of a grammar that has been specialized to the input and only contains those parts of the grammar that are relevant to the input. When the generation guide is analyzed to determine internal facts a smaller generation chart is produced.

Abstract: A data classifier classifies a plurality of input pattern data into one or more clusters. For each pattern data, a cluster to which the pattern data belongs is provisionally determined. For each cluster, a predetermined correlation value is calculated between one or more pattern data belonging to the cluster and observational pattern data which is a target to be classified into a cluster. A cluster to which the observational pattern data belongs is determined based on the correlation values.

Abstract: A digital scanner or copier is provided that can dynamically adjust the black point of an image to be scanned based on detected background level of the document. A pre-scan acts on a small scanning window near a leading edge of the document to obtain a histogram of grey-level values. From this, the background level of the document can be obtained to determine a white point of the image. Additionally, a black point of the image is originally set to a default offset value. However, an adjustment factor based on the detected white point is used to adjust the default offset value to a value that increases the dynamic range of the output image, while still maintaining solid black for black areas of the image.

Abstract: A pointing device is provided, enabling to specify a position in a predetermined space easily. A ball is rotatably fitted in the bottom of a body of a pointing device, and the ball rolls when the body moves over a reference surface. A first displacement detecting unit detects displacement of the body relative to the reference surface by detecting the rolling of the ball. A fixed member is fixed to an upper part of the body by way of an elastically bendable supporting member. The moving member can displace relative to the fixed member, and this displacement is detected by a second displacement detecting unit. When the moving member is depressed, the fixed member presses a switch. The switch thus detects whether or not the moving member is being depressed.

An information processing unit processes, upon request from a user, work data in a joint work data management unit and personal work data management units. A shared activity information management unit and personal activity information management units manage joint work data and personal work data in the joint work data management unit and the personal work data management units as activity information. An activity information tracing unit, on the basis of activity information separately managed by the shared activity information management unit and the personal activity information management units, extracts particulars of a sequence of operations performed on a specific activity. The states of activities can be thereby kept track of, including activities personally carried out by individual users.

Abstract: Gallium nitride substrates are formed by etching a gallium nitride layer on a sapphire substrate or by selective area regrowth of a gallium nitride layer first deposited onto a sapphire substrate. The gallium nitride layers are bonded to a support substrate and a laser pulse directed through the transparent sapphire detaches the gallium nitride layers from the sapphire substrate. The gallium nitride layers are then detached from the support substrate forming freestanding gallium nitride substrates.

Abstract: This invention provides a scheduling scheme that uses an estimated rasterization execution time (RET) to improve the productivity of printers, particularly color printers. Because print jobs have different levels of complexities, a longer RET may be require for some jobs than for others. For example, a print job which includes color graphics, color print, different font changes or a variety of style formats such as, italic, bold and other styles, will have a longer RET than a simple black and white print job. If a print job is pre-scanned to estimate the RET before the print job arrives at the printer, it is possible to schedule those print jobs with a shorter RET ahead of those print jobs with a longer RET, thus improving productivity of the printer.
