Patent EP-0375143-A2 (EP)
Inventor: HEYEN JOHN GARY
IPC: G06Q10/10
Filed: 1989-11-10
Abstract: A method is disclosed for providing a user dependent status indication for shared electronic mail objects within a distributed computing system. In certain electronic mail systems multiple users are permitted to share access to selected electronic mail objects in a so-called "affinity" relationship whereby selected end users are permitted to access identical address space within a computer. Within such systems it is difficult to ascertain a particular status of a selected electronic mail object with certainty due to the fact that multiple users may have access to that electronic mail object. An attribute list is associated with each electronic mail object which may contain multiple sets of attributes, each set associated with a group of recipients, a subgroup of recipients or an individual end user having access to that electronic mail object. Thereafter, the activities of each end user are used to modify each attribute list associated with that end user. An end user may then periodically determine and display the status of an individual mail object with regard to the entire group of recipients, a subgroup of recipients or an individual end user.

Abstract: A computer connected to an ISDN central office switch via an ISDN digital subscriber line, provides management information regarding activities of a plurality of telephone agents. The computer has shared call appearances with a number of telephone agent stations and receives shared call appearance associated messages from the switch reflecting call handling messages exchanged between the ISDN switch and each of the agent stations. The messages are interpreted by the computer, which generates station status information and management information such as the number of calls handled, average holding time per call, etc. The computer may be connected simultaneously to several central offices via ISDN subscriber lines and generate management information for a group of geographically separated agents, such as home telemarketing agents operating out of their individual homes and connected to different central offices. Based on the generated status and management information, the computer performs an incoming call management function by selecting agents connected to different switches for handling incoming calls and transmitting to the ISDN switch appropriate messages for causing the switch to transfer incoming calls to the selected agents. Additionally, the computer performs an outgoing call management function by initiating outgoing calls and causing the switch to connect an answering party to an agent, selected by the computer on any of the switches.

Title: Pressure sender
Inventor: WASSERSTROM HENRY
IPC: G01L7/08
Filed: 1990-02-07
Abstract: A pressure sender is provided with a variable electrical resistance corresponding to a sensed pressure, to be placed in series with a voltage source and a pressure gauge. The pressure sender is diaphragm-actuated, which diaphragm controls the positioning of an electrical contact against a ceramic thick film rheostat. An electrically conductive metal clip secures the rheostat in position as well as completes the electrical connection between the rheostat and the electrical circuit of which the pressure sender is a part. The electrical contact is rockingly mounted so that deflection of the diaphragm displaces the electrical contact through an arcuate travel path along various resistance positions of the thick film ceramic rheostat. Current from the electrical circuit will flow through the metal clip to input contacts of the rheostat, and then to the resistance positions. The lower the pressure being sensed, the farther away from the input contacts will the electrical contact contact the resistance positions so that lower pressure will result in higher resistance of the pressure sender. By monitoring this resistance, the pressure being sensed can be determined.

Abstract: On transferring transfer data between a peripheral controller (11) and an input-output channel unit (12), an overrun predicting circuit (45) of the input-output channel unit predicts occurrence of an overrun with reference to an amount of transfer data memorized in a buffer memory (39) and produces an overrun prediction signal (46). The overrun prediction signal is delivered to the peripheral controller by the use of a start informing acknowledgement signal line (15) which is used in transferring a start informing acknowledgement signal from the input-output channel unit to the peripheral controller before the transfer data is transferred between the peripheral controller and the input-output channel unit. Responsive to the overrun prediction signal, a strobe inhibiting circuit (21) of the peripheral controller inhibits delivery of a strobe pulse signal from the peripheral controller to the input-output channel unit during a predetermined time interval.

Abstract: Herein disclosed is a camera recording system which is capable of selectively imaging an image having an aspect ratio - a ratio between the horizon­tal length and vertical length of a frame - of 4 : 3 as in the NTSC system and an image having a horizon­tally longer aspect ratio of m : n (m/n > 4/3) than the former ratio. Further disclosed is a usable meth­od which allows the user to take only one turn for selecting the aspect ratio. The method is represented by three kinds: one using a lens unit; another using the scanning range of an image tube; and still another using an expander circuit. What is required of the user is only one turn of switching the lenses or switches, and the remaining necessary switching opera­tions are automated.

Abstract: Bei symmetrisch sperrenden Thyristoren und bei Dioden ist für manche Anwendungsbeispiele eine Absenkung der anodenseitigen Speicherladung erwünscht. Dies wird durch in der anodenseitigen Emitterzone liegende Kurzschlüsse erreicht. Diese werden zwischen in der Emitterzone eingebetteten Zonen (10) eines ersten Leitungstyps und Zonen eines zweiten Leitungstyps gebildet. Die Zonen des zweiten Leitungstyps sind tiefer als die des ersten Leitungstyps und überlappen die Zonen des zweiten Leitungstyps teilweise. Bei niedriger Stromdichte sind diese Kurzschlüsse unwirksam, bei hoher Stromdichtesind sie wirksam. Kurzschlüsse dieser Art lassen sich auch bei speziellen Dioden auf der Katodenseite verwenden, die als Freilaufdioden für GTO-Thyristoren eingesetzt werden sollen, sowie bei asymmetrischen GTO-Thyristoren auf der Anodenseite. <IMAGE>

Abstract: The present invention relates to a technique in the form of an exemplary computer vision system for detecting the orientation of text or features on an object of manufacture. In the present system, an image of the features or text (10) is used to extract lines using horizontal bitmap sums, and then individual symbols (12) using vertical bitmap sums while using thresholds with each of the sums. The separated symbols are then appropriately trimmed and scaled to provide individual normalized symbols (14). A Decision Module (15) comprising a Feed-Forward Neural network (21) and a sequential decision arrangement (23) determines the "up", "down" or "indeterminate" orientation of the text after a variable number of symbols have been processed. The system can then compare (24) the determined orientation with a database to further determine if the object is in the "right-side up" "upside-down" or "indeterminate" orientation.

Abstract: Repetition pull-through blind riveting apparatus (10), of the type comprising a reusable and reloadable mandrel with an enlarged head which is pulled through each tubular rivet in turn to install the rivet is provided with a safety device (141) for counting the total number of times the mandrel has been pulled. The apparatus includes pneumatically-operated mandrel pulling means, and a counter (132) counts the number of times the pressure of the air powering the pulling device reaches a pressure slightly below that required to pull the mandrel head through a rivet. The counter (132) is arranged to actuate, when a safe limit number of pulls has been counted, both a shut-off valve (137) to shut-off the supply of pressure air to the mandrel pulling means, and a visual indicator (135). The visual Indicator (135) may be actuated at a warning count number rather lower than the safe limit number. The counter (132) can be reset to zero only by use of a separate key (142), when a new mandrel is installed in the rivet placing apparatus.

Abstract: A method and apparatus which corrects the amplitude variation in the output in an electro-optic modulated laser system (10). Birefringence within the electro-optic crystal (25) causes elliptical polarization of the linearly polarized laser light (22) produced by the laser gain medium (16), in turn causing a loss in the laser output (27).
