Patent EP-0301841-A2 (EP)
Inventor: ZUCKER JOSEPH
IPC: G02B6/00
Filed: 1988-07-27
Abstract: A distribution optical fiber network includes a light source (9) having a mode volume less than a distribution optical fiber (4), the light source being connected to the fiber so as to minimize the number and order of modes initially supported by the fiber by aligning an optical center of the light source with a geometric center of the fiber. 
     It has been surprisingly and unexpectedly discovered that optimally aligning geometric centers of a light emitting surface of a light transmitter with the geometric surface of an optical fiber end so as to achieve optimum light throughput at an opposite second optical fiber end is disadvantageous where the fiber is to be used in a distribution system with a plurality of side taps which induce a plurality of bends to the fiber, especially macrobends.

Abstract: An improvement is disclosed to the conventional field related help/dialog facility in an interactive data entry data processing system. The improvement comprises a technique for tracking the number of times a user has invoked a help/dialog function, comparing that number to a threshold value and then displaying less help/dialog information to the user from that point on. Additionally, the application tracks the number of elapsed days since a functional area has been used. Once the number of elapsed days reaches a threshold, the user is reset to a status in which all the help/dialog information is once again displayed. This is accomplished by building a data base of help/dialogs which are uniquely addressed by the functional area and skill level of the individual user.

Abstract: An integrated and compact separator for removing both solid and gaseous contaminants from fluid. Fluid to be cleaned is introduced tangentially into a vortex flow chamber (11) before or after filtration of the fluid. The fluid stripped of gaseous contaminants passes through pores (14) in the outer wall of the vortex flow chamber while gas-rich fluid collected near the center of the chamber passes into a gas removal pipe (17) extending in the chamber at its axial center. After solid and gaseous contam­inants are removed by the separator, the fluid flows out of the separator.

Abstract: A multilayer printed circuit memory board is designed and constructed so that the top and bottom layers contain repetitive integrated circuit (IC) chip component hole/pad and interconnection line patterns which are mirror images of one another. The board uses surface mounted techniques in which the integrated chip components of the memory array are mounted and soldered to both sides of the board thereby doubling the density or capacity of the memory board. The integrated circuit memory chips, mounted on the top and bottom of the board, are aligned with each other for sharing common holes or vias in which logically equivalent input signal connections are exchanged in a manner for reducing the number of holes and length of connective wiring.

Abstract: A task scheduler system including an array of priority queues for use in a real time multitasking operating system including equation lists, configuration lists, a function library, input and output drivers, user-created task definition lists of major and minor tasks and interrupt handlers. The system includes task scheduling which, upon the completion of each library function, interrogates the priority queues and finds the highest priority task segment whose requested resource is available and executed, and which executes task segments in the same priority queue in round-robin fashion. The system further includes task creation including updating and interrogating the user-created lists. The system still further maintains the status of all major tasks in a system in the states of unlocked and done, unlocked and active, unlocked and waiting, locked and active, or locked and waiting and the system locks tasks into a mode of operation such that the task scheduler will only allow the locked task to execute and the normal state of priority execution is overridden, and it waits for suspending operation on a task that requires completion of a library function.

Abstract: The present invention relates to apparatus for processing documents arising in financial transactions which include numerical figures, such as bank checks, credit card drafts, and the like. 
     According to the invention the predetermined numeric fields containing the handwritten numerical entries are automatically located in the pixel array, the numeric fields are subjected to character recognition analysis, and a confidence level is associated with each such numeric field reflecting the degree of confidence with which the apparatus has recognized the numeric dollar amounts. The transaction is automatically balanced from the data in the system by computing a combined value of the recognized dollar amounts making up a transaction and comparing the combined value with the transaction total. This computation and comparison is performed automatically, without the prior intervention or assistance of a human operator to review, verify, correct or otherwise modify the dollar amounts recognized by the system.

Abstract: For a coffee brewing machine (20), an indicating system which operates to notify the user when it is time to clean the water supply conduit (28, 36, 31) of accumulated mineral deposits. When a self contained removable reservoir (24) is inserted into its operative position connecting to the water supply conduit, it closes the contacts of a temperature sensitive switch (78). During normal operation, the temperature sensitive switch (78) opens when water is depleted from the reservoir (24) and the brewing cycle is completed. However, if the temperature sensitive switch (78) opens while water remains in the supply conduit upstream of the heater mechanism (32), this is a sure indication that there is a substantial acoumulation of mineral deposits in the supply conduit. A sensing mechanism (80; 134, 136) is employed to detect the presence of water in the supply conduit (28) after the temperature sensitive switch (78) opens, and a lamp (120) is energized to indicate the condition. In one embodiment, the sensing operation is performed by an electromechanical device, and in another embodiment by logic circuitry.

Abstract: An improved pressure swing adsorption process is disclosed for the recovery of high-purity primary and secondary components from a multicomponent gas mixture. The process utilizes a first group of adsorbent beds selective for the secondary component and a second group of adsorbent beds selective for retention of tertiary impurities in the mixture. The gas mixture is passed through a first and second bed in series, very high purity primary component product is discharged from the second bed, and high purity secondary component product is recovered by desorption from the first bed. A low-pressure purge of the first bed with high-purity secondary component product is utilized to minimize compression power and improve purity of the secondary product component. Several novel pressure equalization steps improve primary product recovery and reduce power consumption. Further increased product recovery is realized by recycling depressurization and purge streams from the first bed. The process can be used to recover high-purity hydrogen and carbon dioxide from a gas mixture containing these components along with minor amounts of methane, carbon monoxide, and nitrogen.
