Title: Concurrency control through a class library in object oriented technology
Inventor: O'FARRELL WILLIAM G
IPC: G06F9/42
Filed: 1993-06-01
Granted: 1998-12-01
Abstract: A mechanism for controlling method invocation and avoiding problems such as premature method execution before object construction and premature object destruction before method completion, is provided through a protocol function table in a class library. For any virtual functions declared in a class library, the thread of control invoking the function is re-directed through the protocol function table where it is either selectively accepted or delayed for later acceptance pending completion of some related procedure. When used in conjunction with an automatic routine for locating the originating point in an operating program, the protocol function table is particularly useful for executing concurrency in object-oriented applications.

Abstract: An automatic protection and recovery method for a telephone line interface circuit is described. The interface circuit monitors current on the line, and in the event of a fault producing an excessive current a protection relay interrupts a connection of the interface circuit to the line, and the interface circuit monitors common mode voltage on the line. The interface circuit is reconnected in response to the monitored voltage being below a relatively high threshold. If a second interruption results, the interface circuit is then reconnected in response to the monitored voltage being below a lower threshold. If a further interruption results, the interface circuit enters a ground fault recovery process. The method facilitates protection and rapid recovery from arbitrary fault conditions on the telephone line.

Granted: 1998-08-11
Abstract: A frequency stabilizer for use in a time-division multiplexed digital cellular system is designed to reduce the consumption of electric power by means of a receiving circuit in continuous frequency control.  The frequency stabilizer includes a pair of latches 4 and 5 for latching a phase error of an output signal from a phase error integrating circuit 2, a subtractor 6 for outputting the difference between respective output signals from the latches 4, 5, and a selector switch 8 for selecting and outputting an output signal from a phase-to-frequency converter 3 in the period of a reception slot and an output signal from a frequency correcting circuit 7 between reception slots.  When the selector switch 8 is selecting the output signal from the frequency correcting circuit 7, no electrical energy is supplied to the receiving circuit.  Even when the frequency stabilizer is in continuous operation, the receiving circuit operates only during the reception slot, resulting in reduced consumption of electrical energy.

Abstract: A personnel protection system for electrical connections is disclosed, which is of the type that differentially senses the cur-rent flow between the power lead (50) and the return lead (52) (or between two power loads) is provided with an unbalancing im-pedance (70) which makes the current difference between the two leads sufficiently high to trip the device (48) and cause the pow-er to be disconnected. A utilization device (64) is similarly provided with an imbalanced impedance (80). However, that imped-ance is calculated to counteract the current imbalance caused by the first impedance (70), so that when the cable is connected to the utilization device (64), the current balance between the two conductors (50, 52) is restored, and power connection is main-tained in the cable. Thus, the system does not provide continuous power unless predetermined conditions considered safe for sec-uring the power are fully satisfied.

Abstract: A collapsible luggage  trolley includes a  wheeled base from which two parallel posts extend upward with a  handhold mounted on the free ends thereof and a middle support member connected between the  posts at a  middle position  thereof.          Each of the posts has a lower, a middle and an upper tubular sections  telescopically  received  within  each  other  and retained in the  expanded position by  the first and  second retaining pins  which  are biased to extend  through  holes formed  on the  tubular sections.   A plug  movably received within  the  upper section  is  connected to  a  release bar disposed within the handhold by a link to allow the  plug to be controlled by the release bar.  A cavity is formed inside the  plug  for receiving  therein  the  first retaining  pin between  the  upper section  and  the  middle  section.   An inclined camming surface  is provided within  the cavity  so that when the plug is moved by the  release bar, the camming surface acts upon the first retaining pin to withdraw it for releasing the retaining engagement between the upper section and the middle  section.  The plug has a  round-headed lower end  projecting out of the upper section and into the middle section which when moved to contact the second retaining pin between the  middle section and the lower  section acts upon and moves it back  to break the retaining engagement between the middle section and the lower section.

Granted: 2002-06-25
Abstract: High speed machine scanning of documents such as checks produces digital check images that are placed in archival storage on mass storage devices for later retrieval.  Images and/or documents are automatically reviewed by a machine in order to identify images and/or documents that are of suspect quality. Machine review of suspect images and/or documents provides a reject or accept decision. Only acceptable documents are archived.  Accepted documents are formed into large data groups that contain a storage location identification for each individual document within the large data group. An index is stored for each such data group wherein the storage location of each document within the large data group is contained. Digital images are selectively converted to visual images, and these visual images are then reviewed by a human operator. This operator review is used to adjust the machine's accept/reject decision making process, thereby teaching the machine the correct manner of making its accept/reject decision.

Abstract: A process for making fibre reinforced cellular cementious building materials.  Firstly, mix separately a foam slurry and a cementious mixture containing water and random glass fibres. Secondly, combine the foam slurry with the cementious mixture in a container to form a cellular cementious slurry containing random glass fibres.   The container has a bottom with an orifice positioned adjacent the bottom.  Thirdly,  pull two parallel  spaced  layers  of  integrally  formed  glass  fibre reinforcing mesh through the mixing container filled with cellular cementious slurry and out through the orifice into a drying tray. As the reinforcing mesh passes through the mixing container it pulls along with it cellular cementious slurry. The orifice restricts the amount of cellular cementious slurry that is drawn into the drying tray, thereby serving to gauge the dimensions of the building material.  Fourthly leave the cellular cementious slurry to cure in the drying tray until the cellular cementious slurry has set thereby resulting in a cellular cementious building material having two reinforcing layers of integrally formed glass fibre mesh with random glass fibres extending between the two layers of integrally formed glass fibre mesh.

The apparatus comprises an optical transmitted (2) for projecting a line of light (6) onto the relief pattern at a first angle to a normal of the surface; an optical receiver (3) that views the projected line of light at a second angle to the normal of the surface and produces a signal that is representative of an image of the reflection thereon. The image viewed by the receiver has parallactic displacements (20) of the line of illumination that occur at transitions between raised and recessed portions of the relief pattern (28). The displacements (20) are detected by a pattern detector (4) which is coupled to the optical receiver (3) and submitted to a decoder (5). The optical receiver (3) can be realized as a plurality of light sensors arranged in a linear, or a two dimensional array (22, 26) together with suitable focusing optics (21, 24). The optical transmitter (2) can produce either a fan beam of light or sweep a spot of light across the surface.
