Patent EP-0382416-A2 (EP)
Inventor: GILLON ALEXANDER CARLYLE
IPC: H04N1/00
Filed: 1990-02-02
Abstract: This invention relates to an arrangement for efficiently transmitting facsimile signals from a facsimile source to a facsimile destination using a standard facsimile user interface. The connected switched communications network recognizes that the call is from a facsimile source or to a facsimile destination and causes the facsimile signals to be transmitted at the transmission speed of the source to storage in a network. Subsequently, the signals are transmitted from storage to a facsimile destination at the transmission speed of the destination when the destination becomes available. Advantageously, the source need not wait for the destination to become available before transmitting, and the transmission can take place at a bit rate that matches the source and the destination even when these bit rates are different. Retransmission because of errors in one link is only required for that link, i.e., from the source to the storage or from the storage to the destination. Advantageously, this is accomplished without changing the very simple user interface of prior art facsimile transceivers.

Abstract: Coated gall-resistant surgical saw blades are dis­closed. One such blade (10) includes longitudinal ribs (39/41,43/45) extending outwardly from the opposed faces (15,17) thereof, which combine to define a total blade thickness (X) greater than the width (Y) of the lateral extension of the teeth (27/29,31/33) thereof. The ribs are sized and configured to slidably engage a precision slot (50) in a guide designed to be used to guide the blade in cutting movements. The interaction between the ribs and the slot prevents engagement of the blade teeth with the slot, while reducing the surface area of engagement of the blade with the slot to reduce friction. 
     The blade is coated with a hard, lubricious, metallic, wear-resistant coating comprising a nickel-based alloy including phosphorus, chromium and boron, and the coating process comprises: cleaning the surfaces of the blade; coating the surfaces with binder; dusting the metallic alloy in powder form over the binder; and, heating the blade to drive off the binder and metallurgically bond the alloy onto the surface.

Abstract: An auxiliary video input terminal (S-terminal) (60) couples luminance amd chrominance input signals to respective inputs of peaking circuits (52, 58) in the display processor (40) of a receiver. The chrominance input signal is subjected to pre-­distortion (de-peaking) (80) to correct for sideband amplitude distortion in the chrominance peaking filter of the receiver thereby preventing color distortion in displayed images. The luminance signal is subjected to additional peaking (70) at a frequency greater than the characteristic peaking frequency of the luminance peaking filter thereby enhancing the sharpness of wideband luminance input signals displayed by the receiver.

Abstract: A liquid crystal display which has a small change in contrast ratio and a black level (i.e. background color) when a view point is changed in the upper and lower direction. A nematic liquid crystal material is disposed between two plates (6,4), the plates are oriented (for example rubbed) to cause the liquid crystal material to define a twisted structure in the direction perpendicular to the plates, and the direction of the orientation of the plates is selected so that the normal direction viewing is identical with the direction in which the twisted structure is lost when a voltage is applied across the liquid crystal material. When the direction of viewing is the lower direction, an optical path difference between the plates in the upper area of the liquid crystal display is larger than an optical path difference between the plates in the lower area of the liquid crystal display. When the direction of viewing is the upper direction, an optical path difference between the plates in the upper area of the liquid crystal display is smaller than an optical path difference between the plates in the lower area of the liquid crystal display.

Abstract: The present invention relates to an image processing apparatus and a method of forming an image by separating color information into two or more color information items. The boundary of images is compensated, the images being the images formed by an analog recording system for forming an image on a recording medium by removing a predetermined color component from an original document image and a digital recording system for forming an image on said recording medium by extracting a predetermined color component from said original document image. Therefore, if a slight positional deviation takes place between images formed by the digital recording system and the digital recording system, a want of color information can be prevented. Therefore, the deviation can be satisfactorily compensated so that an original image can be correctly reproduced.

Abstract: Disclosed is a system for collecting (100) and displaying (102) statistical data for a plurality of local area networks (LANs) (103). The data is collected in several remote nodes (100), each of which is attached to a local area network (103). The data is obtained by using a LAN driver (104) that intercepts all records on the LAN (103). The records are sent to a collector process (106) where statistics are accumulated into a shared memory area (108) and then transferred to an archiver process (112) in a management node (102). The archiver process (112) writes the statistics to a history file (114) while compressing older data to prevent the file from growing too large. The file is compressed based on a table of compression schedules, and peak data from samples having varying sampling rates is combined by reducing all sampling rates to the same value and estimating the peak data for samples wherein the sampling rate is changed.

Abstract: Prior to a binary conversion process on a gray-scale image, a user predetermines a binary conversion threshold corresponding to original image density data and stores it in a binary conversion threshold storage unit. In the binary conversion process, the user applies the original image density data to an image processing unit. A binary conversion threshold setter reads a corresponding binary conversion threshold from the binary conversion threshold storage unit based on the original image density data, and the binary conversion processing unit performs a binary conversion process of the original density data based on the minimized average error method using the binary conversion threshold. Thus, the present invention enables desirable reproduction of drawings including characters, eliminating grain noises, and obtaining a high quality image both in drawings and gray-scale portions. The operational error reducer reduces operational errors generated in an average error operation performed in the minimized average error method, and minimizes the deterioration in gradation caused by an operational error.

Abstract: Digital data produced by a document scanner (15) or other data source is sequentially stored in a memory (40). A remote data receiver (45) generates requests for data (43) causing communication of the data(44) from the memory (40) in the same sequence in which it was stored but at a rate substantially asynchronous with respect to the rate of scanner (10) data production. Data (19) is concurrently loaded into the memory (40) and transferred from the memory (40) to the receiver (45) so that continuous data storage and transfer throughout the scan of a given image (11) is possible. Data from the scanner (10) is sequentially loaded into the memory (40) in recycling sequences until there are no available memory storage sections. The scanner (10) is then caused to stop scanning and to cease data production until transfer of data occurs from a memory storage section(0-N) to the remote receiver. The scanner (10) is thereafter enabled so as to resume with production of the next data following that which was last loaded into the memory (40). For a scanner (10), the data interruption and resumption is obtained by stopping and repositioning of the scanner bar (15) relative to the document (11). Scanning is started or restarted when the data in the memory (40) is inadequate to completely satisfy the current receive command (84).
