Abstract: A carrier sensing circuit coupled to a receiving amplifier, measures the frequency of a phase shift modulated carrier signal by counting a predetermined number of the pulses for a measured interval whose duration is determined by counting a first clock count value. A demodulator coupled to the amplifier, detects when the spacing between the edges of the square wave pulses changes in response to the phase shift modulation. The demodulator measures first intervals between consecutive rising edges of the received signal, by counting clock pulses for a second selected interval whose duration is determined by a second selected count value. The demodulator further measures second intervals between consecutive falling edges of the received signal by counting clock pulses for a third selected interval whose duration is determined by a third selected count value.

Abstract: A system is disclosed for the dynamic switching between a first Event Driven Interface and a second Event Driven Interface based upon inband information contained in the data frames of a data communications network. This enables the selective realtime transfer of routing control based upon diverse communications protocols, for example. A first routing table can be contained in a first Event Driven Interface and a second routing table can be embodied in a second Event Driven Interface, and in this example, by means of the first Event Driven Interface identifying the switchover pattern contained within a switching segment of the data frame, the system can automatically switch over to connect a second Event Driven Interface to the data communications network, containing a second routing table configuration. In this manner, realtime control of routing, for example, can be accomplished with inband information in a data communications network.

Abstract: A realtime high speed data capture is provided in response to a trigger bit pattern detected in a serial bit stream. An Event Driven Interface is connected to a data communications network to receive a serial bit stream. A capture buffer is connected to the network to store at least a portion of the serial bit stream. The capture buffer is selectively connected to the network by means of a gate. The Event Driven Interface is programmed to recognize a trigger bit pattern in the serial bit stream and to output an enable signal to the gate. In response to this, the capture buffer will store a predetermined portion of the serial bit stream from the network.

Abstract: The pixel count value in each cell of an array of cells located on a set master forms. Each completed form is scanned into a data processing system and the scanned image is compressed and buffered. In accordance with the invention, when the compressed, completed form is ready to be analyzed, only its top part needs to be decompressed. A form signature set is prepared for the decompressed part of the completed form in the same manner as the master signature set was prepared. The first N rows of the form need to be decompressed and a form signature set created from a pixel count value on each cell of an array of cells located in the decompressed portion of the completed form. The form signature set is compared to the master signature set to determine the best match.

Abstract: The realtime event classification technique is described for a data communications network, which enables the categorization of data frames based upon selection significant bit segments in the serial bit stream. A base Event Driven Interface and an extension Event Driven Interface are both coupled to the data communications network, to identify patterns in the serial bit stream. The base Event Driven Interface identifies patterns which correspond to events which are to be counted. The extension Event Driven Interface identifies patterns of bits which are selection significant for the types of categories which are desired to be monitored. A plurality of event vector counters have event inputs coupled to the base Event Driven Interface and have a selection input coupled to the extension Event Driven Interface. A selection signal output from the extension Event Driven Interface enables one of the plurality of the event vector counters to receive the event signals from the base Event Driven Interface.

Abstract: The method enables realtime establishment and maintenance of a standard of operation for a data communications network. The process begins by monitoring the network over some period of time to build benchmark data sets. The benchmark data sets contain a standard of operation for the network, which is historically categorized by either traffic type or activity. This standard of operation is accumulated by the intelligent monitoring facilities. After a period of accumulation, the benchmark is used to determine whether data taken from current monitoring activity indicates normal network behavior. Network monitoring information is analyzed using criteria in modules that have an interface to an expert system. The criteria modules evaluate the current monitored data against the prior benchmark collected data. The criteria module determines if the current network operating characteristics are outside the bounds of normal behavior. If they are, then alerts and logs of information can be sent to the expert system.

Abstract: A method and system to recognize input events from a plurality of input devices. Each input device is coupled to a device driver or similar device specific code and a recognition provider. Upon attachment to the system, the recognition provider registers the known input events which the input device is capable of transmitting at the recognition subsystem. The recognition subsystem sends an identifier back to the recognition provider for each registered input event. When the recognition provider receives one or more input signals from the input device which are recognized as an input event, the provider sends the identifier to the recognition subsystem. The input event is transmitted to a process running on the system which may interpret the input event or request translation by the recognition subsystem. The invention is useful to introduce new input devices to a system without requiring modification of the existing processes.

Abstract: A multimedia document form system enables the definition, manipulation, storage and editing of a form which contains multimedia objects. Image objects and text objects can be displayed on the form in the conventional manner. Nonvisual presentation objects such as video objects and audio objects are represented by check boxes on the form. If a nonvisual object is to be associated with the form, then a mark is applied to the corresponding check box on the form. When the form is scanned-in in an optical scanner, presence of a mark in the check box prompts the operator to enter the nonvisual object. For example an audio object will be entered in digitized form and stored in association with the form. When the form is then displayed on a visual display device, the corresponding check box is highlighted to indicate to the operator the presence of a nonvisual presentation object which is stored in association with the form.
