  • Patent number: 5970126
    Abstract: The present invention relates to establishing a communication channel between two communication systems having computer telephony integration (CTI). Many CTI systems are configured into incoming and outgoing lines according to the anticipated demands. Consequently, if sufficient outgoing or incoming capacity is unavailable at a given time to support a communication channel of required characteristics, the users of such a system must conventionally wait until sufficient capacity becomes available. However, the present invention determines who the intended addressee is and can instruct the CTI system associated with that addressee to instigate the establishment of a communication channel to the user who originally desired the connection. The instructions can be sent to the intended addressee using for example, another communication network, such as the Internet or other data communications network.

  • Patent number: 5940490
    Abstract: A method of routing a call including a called number in a communications network such as a Public Switched Telephone Network (PSTN), the method including determining if the called number is a network routing number indicating a specific switching node and line associated therewith in the communications network and routing the call within the communications network based on the called number when the called number is a network routing number. Additionally, the method includes identifying a network routing number based on the called number when the called number is not equal to the network routing number and routing the call within the communications network based on the identified network routing number.

  • Patent number: 5844158
    Abstract: The invention relates to a voice processing system capable of outputting voice prompts and background music. The volume of background music is progressively variable relative to the voice prompts or speech. The progressive variation is effected by multiplying the background music samples by a scaling factor and then adding together a current voice sample and the scaled background music sample. Accordingly, when the combined samples are output to the user the volume of the background music varies.

  • Patent number: 5812836
    Abstract: A data processor comprises storage (e.g., registers) for each of first, second and third values, a processor condition register for processor condition codes, and logic for decoding instructions including a specific instruction defining an operation between the first value and either the second value or the third value, the selection of the second or the third value being made by the processor in dependence on the state of said processor condition code. The invention is of particular, but not exclusive, application for the plotting of lines in a display system. In an example of a display system incorporating such a data processor, a pixel can be plotted on each processor instruction cycle.

  • Patent number: 5812644
    Abstract: A voice processing system comprises a computer workstation 80 running a voice system software and a telephony interface module 70 which is attached via a trunk line 100 to a telephone switch 10. The computer system 80 and the telephony interface module 70 are connected by a standard data connection 230 such as a SCSI connection over which voice data is exchanged. The SCSI interface is provided with a voice device driver capable of handling voice data by means of an appropriate set of commands.

  • Patent number: 5724404
    Abstract: An integrated international telephone circuit monitoring system to restrict and substantially prevent abusive types of international telephone call reorigination, the system including a circuit monitoring card to monitor international telephone circuits from a reorigination country and thereby detect DTMF tones associated with telephone call reorigination and transmitted over the international circuit, and/or a second dial tone associated with the initiation of an international reorigination call, on a connection completed call, for subsequent blocking. Additionally, the telephone circuit monitoring card is structured to detect questionable DTMF tone dialing patterns associated with telephone call reorigination for subsequent blocking of completed transmission of the DTMF tone codes.

  • Patent number: 5220801
    Abstract: A method and apparatus for maintaining a liquid-frozen solid slush mixture in a vessel at a desired total slush mixture and desired solids content during conditions under which the solids in the slush mixture in the vessel are melting. The method comprises introducing fresh slush mixture to the vessel, while removing liquid from the vessel--both at rates directly proportional to the rate of solids melting in the vessel. The apparatus comprises an auxiliary vessel containing slush mixture and means for transferring slush mixture to the main vessel at one rate, means for transferring liquid from the main vessel to the auxiliary vessel at another rate, and means for controlling the transfer rates in a prescribed manner.

  • Patent number: 4267449
    Abstract: A method for detecting leaky ampules filled with a liquid such as a parenteral solution. The ampules to be tested are immersed in a solution containing a short-lived radionuclide, and a pressure differential is imposed between the solution containing the radionuclide and the parenteral solution or other liquid contained in the ampules. The ampules are then removed from solution, decontaminated to remove any solution adhering to the outer surface and pores thereof, dried, and finally examined for electromagnetic radiation, preferably gamma radiation, emanating from the interior of the ampules which would indicate a leaky condition thereof.

  • Patent number: 4158114
    Abstract: A switching device is provided which permits connection of two incompatibly wired electrical components. The electrical signal from each lead on the first electrical component is isolated on a particular switch assembly and re-routed along a selected path to a desired terminal, which then feeds the signal to a particular lead on the second electrical component. Each switch assembly operates independently of the other switch levels, thereby permitting any combination of electrical routes or paths to be selected and accommodating a great variety of wiring designs.

  • Patent number: 3939551
    Abstract: A method for manufacturing an oil seal element from polytetrafluoroethylene and the like. A tubular billet of polytetrafluoroethylene or the like is provided with an outer cylindrical surface of the desired diameter and an inner cylindrical surface approximating but slightly smaller than the desired diameter, and an end wall is faced off perpendicular to the cylindrical surfaces. A series of washers of a desired thickness is then sliced from the billet. The flat washer is then first assembled with a metal case and then a desired hydrodynamic shape, such as a spiral groove, is coined in. Preferably, the inner pierce is completed at this time. Each washer may then be formed under pressure to permanently deform the radially inner portion thereof to a frustoconical shape. The assembled seal may be held on a shaft-size mandrel during application of a coating to the metal case.
