Patent EP-0415862-A2 (EP)
Inventor: CORRIGAN MICHAEL JOSEPH
IPC: G06F5/16

Abstract: A computer system (10) having optimized I/O buffers (31, 32) is disclosed. The I/O buffers are used to write data into or read data from auxiliary storage (50). A double buffering scheme is used. When a user wants to send data to auxiliary storage, the first buffer is filled with data and the contents are asynchronously written to auxiliary storage. Without waiting for the asynchronous write to complete, the second buffer is filled with data. When the second buffer is filled, the contents of the second buffer are asynchronously written to auxiliary storage. If the first buffer has not completed its write operation by this point, the buffers are determined to be too small and the size of both buffers is increased. Control switches back and forth between these two buffers until all of the desired data is sent to auxiliary storage. The size of the buffers is increased until the computer system does not have to synchronously wait for one buffer to complete its write operation before it can refill that buffer with new data. Ideally, the first buffer should complete its write operation when the second buffer is filled beyond a predetermined threshold percentage, such as one half. If the first buffer completes its write operation before the second buffer is filled beyond the predetermined threshold percentage, the buffers are determined to be too large and the size of both buffers are decreased. The size of the buffers is dynamically increased and decreased as needed to achieve an optimum size based on the unique and dynami­cally changing computer environment.

Abstract: In a cordless telephone system, several speech channels are periodically scanned by a base station during a standby mode to detect idle channels from the scanned channels. In response to receipt of a call request from a cordless station or an incoming call from a switched telephone network, the base station transmits a channel indicating signal to the cordless station over a control channel indicating that the detected idle channels can be used as possible candidate channels, switches to a first candidate channel and waits for an end-of-switching signal from the cordless station until a prescribed period of time expires. On receiving the channel indicating signal, the cordless station switches to the first candidate channel and makes a channel check on it and transmits an end-of-switching signal if it determines that the first candidate channel is idle. If the end-of-switching signal is not received from the cordless station before the prescribed period expires, the base station switches to a second candidate channel. If the cordless station determines that the first candidate channel is busy, it switches to the second candidate channel and makes a channel check on it. If the cordless station determines that the second candidate channel is idle, it transmits the end-of-switching signal over the second candidate channel.

Abstract: A video signal processing circuit for providing a compressed picture insertion function in a television receiver, whereby a compressed-size picture expressed by one video signal is displayed as an insert within a full-size picture that is expressed by another video signal, by demodulating and combining the video signals, which can be of respectively different television standards, such as the PAL and MUSE standards. The circuit utilizes only one demodulator circuit for one video signal and two demodulator circuits for the other signal. When one of the video signals is in accordance with a broadcast standard such as the MUSE standard, which requires a large-scale demodulator circuit, a significant reduction in overall circuit scale is achieved by comparison with the prior art, in which two demodulator circuits are required for each of the video signals.

Abstract: An on-board satellite signal switching assembly receives uplink beams of any ITU-allocated satellite signal transmission band (i.e., C-band, Ku-band, Ka-band) and converts these received beams to electrical signals. The electrical signals are converted (preferably down-converted) to a common bandwidth and input to a switch matrix which defines transmission paths between uplink and downlink beams. Outputs of the switch matrix are re-converted to downlink beams for transmission to desired earth stations. In this way, complete connectivity among between uplink beams of any band and downlink beams of any band is accomplished. Ground-to-ground communications systems may also benefit from these techniques.

Abstract: In premix gas burners consisting of a number of perforated cylinders (1, 2, 3) arranged concentrically with one another, the cylinders undergo different thermal expansions as a result of the different temperatures. The resulting thermal stresses are to be prevented. This is achieved in that the cylinders (1, 2, 3) are rigidly mounted only at the inflow end of the mixture on a common front element (4, 4') and at the opposite end are in each case, freely movably in relation to one another, closed with an individual closure element (5). Non-perforated end zones (b) serve as cool compensation sections between the hot cylinder surfaces (a) and the front and closure elements (4, 4', 5). <IMAGE>

IPC: B05C3/00
Filed: 1992-11-28
Abstract: A fluid treatment apparatus and method wherein uniform treatment of a substrate (e.g., a thin, metallic sheet) is treated (e.g., etched) during movement thereof. This treatment involves directing a plurality of fluid jets through a collected first fluid onto one of the substrate's surfaces in such a manner that the fluid of each fluid jet will engage (collide with) the fluid from the nearest fluid jet as a result of being maintained across the substrate's surface at a predetermined velocity prior to mixing of the jets with surrounding fluid. Prevention of such mixing prior to such engagement has proven to assure uniform treatment of the substrate. In one aspect of the invention, fluid is directed onto opposite surfaces of the substrate in this fashion, the fluid from the lower surface, however, being passed through air or similar ambient and thus prevented from mixing therewith prior to such engagement.

Abstract: A processor (282) measures size or spacing of connected components for an image of text by obtaining a distribution of measurements of distances between edges of connected components. The distances are measured along lines extending in a measuring direction, such as a direction parallel or perpendicular to lines of text, which can be determined based on a measurement of skew. The distance measurements then can be used to produce a distribution of measurements as a function of distance, such as a histogram. Sufficient distances are measured for the histogram or other distribution data to indicate a measure of size or spacing of connected components for the image, such as a stroke width, a maximum character width or height, or a spacing between characters, words, or lines. To measure sizes, distance can be measured across pixels within connected components. To measure spacings, distance can be measured across pixels that are not within connected components. Measurements in a direction parallel to lines of text can indicate intercharacter spacing, interword spacing, vertical stroke width, and maximum character width. Measurements in a direction perpendicular to lines of text can indicate interline spacing, horizontal stroke width, and maximum character height. A machine could store an input image in memory, obtain data indicating size or spacing of connected components, modify the stored data according to the sizes or spacings indicated, and provide an output image based on the modification. The data indicating size or spacing could be used in segmentation and character recognition.
