Patent EP-0388050-A2 (EP)
Inventor: PUTZ STEVEN B
IPC: G06F12/00
Filed: 1990-03-01
Abstract: A database system (51) is provided for interchanging visually-faithful renderings of fully-­formatted electronic documents among computers having different hardware configurations and different software operating environments for representing such documents by different encoding formats and for transferring such documents utilizing different file transfer protocols. All format conversions and other activities that are involved in transferring such documents among such computers essentially are transparent to their users and require no  a priori  knowledge on the part of any of the users with respect to the computing and/or network environments of any of the other users. 
     All database operations are initiated and have their progress checked by means of a remote procedure call protocol which enables client applications to obtain partial results from them relatively quickly, without having to wait for such operations to complete their work. These database operations are forked as child processes by a main database server program, so the functionally of the database system may be extended easily by adding further database operation programs to it.

Abstract: A CRT heater circuit for a CRT display is described, the circuit comprising control means (4) for dynamically varying a voltage (Vh) across the cathode heater in response to variations in the beam current density (I) within the CRT. In this way the optimum voltage across the heater coils is maintained, thus preventing "cathode stripping" at times of peak beam currents, and optimising the CRT's working lifetime.

Abstract: A phase difference detection unit for an automatic focusing system of a camera or the like. The phase difference detecting unit includes a pair of linear image pickup devices which receive a pair of optical images of an object formed by the lens in the automatic focusing system of a camera or the like. The detecting unit also has a correlation operating circuit which determines whether or not the lens of the focusing system is in a proper focus condition. The proper focus condition is determined by a minimum correlation value output by the correlation operating circuit, the value being indicative of the correlation between a pair of phase shifted analog electrical signals representative of the optical images received by the pickup devices. The correlation operating circuit is capable of operation at high speed with improved accuracy by maintaining the capacitive loads of the input terminals of the correlation operating circuit.

Abstract: A novel epoxy resin containing a norbornane ring is formed by polymerizing a norbornane compound containing an epoxy group in the ring and an epoxyethyl or epithioethyl group bound to the ring. 
     This epoxy resin can be cured in a usual manner. The cured product is, because of the norbornane skeleton, excellent in hardness and strength and low in moisture absorption. Compared to an epoxy resin having an aromatic ring, said epoxy resin is excellent in electrical characteristics since it is free from Na, Cl, etc., and is suited for use in sealing materials of LSI, etc. The compound containing the epithioethyl group is high in refractive index because of the epithioethyl group and can be used also in the optical field.

Abstract: An equipment unit protection switch from an in-service equipment unit to a standby equipment unit is realized prior to any movement of the active equipment unit about to be removed from an equipment frame in which it is inserted. This is achieved by advantageously incorporating apparatus for generating an equipment unit removal indication signal that enables a controller to anticipate the removal of the equipment unit from the equipment frame. To this end, the equipment units employ an equipment unit latch and an associated switch to generate the equipment removal indication signal. Initial movement of the latch causes the equipment unit removal indication signal to be generated prior to any movement of the equipment unit in the frame in which it is inserted.

Abstract: An apparatus for capturing and recording the content, ownership, and/or bibliographic source of documents reproduced on a reprographic device, and more particularly for tracking the reproduction of specified information, especially copyrighted documents, is connected, preferably detachably, to any of various reprographic devices. The apparatus includes a digitizer for digitizing desired pages (such as those containing title and author information) output from a main portion of the reprographic device, a recording device and medium for storing said digitized pages, a counter for counting the number of reproductions made and optionally inferring the number of originals, a controller for controlling the operation of the apparatus and, optionally, a control panel for interacting with the operator of the reprographic device. When reproducing copyrighted information, an operator makes a reproduction of the pages containing title and author information, digitized images of these pages being stored on the recording medium. The counter counts the total number of copyrighted and other reproductions made, the counted number of reproductions also being recorded on the recording medium. The recording medium is then used to determine the number and nature of copyrighted reproductions made by the reprographic device. The device may also be used for other applications where reproduction of particular types of documents is restricted, or for storing document contents as part of an information storage and retrieval system.

Abstract: The invention relates to a system for free-space optical transmission of frequency-modulated or pulse-modulated signals with one or more stationary light-transmitting units and a focusing optical system connected to these optical transmitting units and with one or more optical receiving units with a focusing optical system connected upstream. There is, however, in applications in which the transmitter is stationary whereas the receiver is mobile, the disadvantage that the transmission power is inadequate for infrared light as soon as a wide reception angle is required at the receiving end. The object is therefore to indicate a device of the aforementioned type in which the abovementioned disadvantages are overcome. This is achieved according to the invention by designing the optical lens disposed at the transmitting or receiving end or a corresponding lens system in such a way that the focusing effect is great in the vertical direction, i.e. a narrow beam angle is produced in the vertical direction. Little or no focusing effect is produced in the horizontal direction so that a wide beam angle is created here. <IMAGE>
