Abstract: The present invention provides an apparatus that automatically adjusts self-noise which apparatus can lower the lower limit value of a measurement range by reducing the effects of self-noise on measured values. This apparatus corrects self-noise when amplifying an output signal from a sensor 1 so as to conform to a sensor sensitivity G, further processing the amplified signal, and then outputting the processed signal as a measured value. This apparatus includes a sensor sensitivity adjusting circuit 3 that adjusts an amplification factor so as to conform to the sensor sensitivity G, a self-noise value calculating circuit 4 that calculates a self-noise component FnullN from the amplification factor adjusted by the sensor sensitivity adjusting circuit 3 so as to conform to the sensor sensitivity G, and a measured value correcting circuit 6 that calculates a true measured value FnullS from the self-noise component FnullN calculated by the self-noise value calculating circuit 4 as well as a measured value L containing the self-noise component FnullN.

Abstract: A data processor and a method for processing data is disclosed. The processor has an input port for receiving packets of data to be processed. A master controller acts to analyse the packets and to provide a header including a list processes to perform on the packet of data and am ordering thereof. The master controller is programmed with process related data relating to the overall processing function of the processor. The header is appended to the packet of data. The packet with the appended header information is stored within a buffer. A buffer controller acts to determine for each packet stored within the buffer based on the header within the packet a next processor to process the packet. The controller then provides the packet to the determined processor for processing. The processed packet is returned with some indication that the processing is done. For example, the process may be deleted from the list of processes. The buffer controller repeatedly makes a determination of a next process until there is not next process for a packet at which time it is provided to an output port.

Abstract: An LSI device comprises: an FIFO buffer in which transmitting data is written, and from which the transmitting data is output in the order of the writing; a controller for transmitting the transmitting data to the FIFO buffer in response to a write interrupt signal; and an FIFO controller for generating and outputting the write interrupt signal to the controller in accordance with a state wherein the FIFO buffer is empty, and for variably setting a variable interval for the write interrupt signal. According to the present invention, since the FIFO controller can generate the write interrupt signal in accordance with the state wherein the FIFO buffer is empty, and can set a variable interval for the write interrupt signal, an optimal writing process for the system can be implemented, and the frequency at which communication errors occur can be reduced.

Abstract: A method of providing the inputting units of the scanner with a foolproof function. Initially, while a specific inputting unit is activated, such as a push button being pushed, the connection between the operation of the scanner and other inputting units is terminated. This terminated connection is not regained until the specific action, which corresponds to the specific inputting unit, finishes. Moreover, an nullactivationnull message can be directly displayed on the scanner while this specific inputting unit is activated, and while the scanner is processing some specific action, this action can be terminated with the function of the scanner and the connection between all inputting units regained as soon as this specific inputting unit is activated again. For any scanner with the foolproof function, while a specific inputting unit is activated, not only a corresponding specific action is performed but also the connection between the performing specific action and all inputting units is controlled.

Abstract: A technique is disclosed for selectively scanning or encoding a desired region of a document. The desired region is identified via scannable indicia on a control form. The region may be outlined by a border preprinted on the form or traced by a user. Preset selectable regions may be identified by codes or other textual descriptions on the form. The form is scanned and the instructions selected by the user are encoded. The selected region is identified and scanned. Only the selected region is scanned, or a larger region is scanned and extraneous data not corresponding to the selected region is eliminated from the resulting data set. The technique permits elimination of unwanted portions of a document automatically, the reduction in scanned file size, and straightforward handling of batch scanning tasks in which selected portions of documents are to be scanned and processed.
