Abstract:
A system for permitting insertion or replacement of electronic cards, the system includes a scanner for scanning hardcopy elements, the scanner including an electronic component for performing at least one processing function on an electronic representation of the hardcopy element; a first processor for directing operations of the scanner and for receiving directions that are passed to other components; a field-installed electronic card that performs additional processing on the electronic representation of the hardcopy element; a second processor electrically connected to the scanner for sending directions to the scanner processor which processor includes field-installed control code for directing the field-installed electronic card.
Abstract:
A synchronous network traffic processor that synchronously processes, analyzes and generates data for high-speed network protocols, on a wire-speed, word-by-word basis. The synchronous network processor is protocol independent and may be programmed to convert protocols on the fly. An embodiment of the synchronous network processor described has a low gate count and can be easily implemented using programmable logic. An appropriately programmed synchronous network traffic processor may replace modules traditionally implemented with hard-wired logic or ASIC.
Abstract:
A software enabled, matrix switch is presented wherein a scalable plurality of inputs, coupled to media content sources, provide media content which is recursively routed through select media processing object(s) coupled to a scalable plurality of matrix switch outputs in accordance with a user-defined media processing project.
Abstract:
A multi-function apparatus and method for receiving and printing an electronic letter is provided for a plurality of users. An electronic letter receiver converts received data from a mail server into image and character data and outputs the image and character data. A letter storing unit sorts and stores the image and character data by the users' accounts. A display unit displays information extracted from the image and character data. A user interface unit outputs a display requesting signal when an authorized user requests to view letters for the user and outputs an account control signal having information selected by the authorized user from the displayed information. A controller stores the image and character data received from the electronic letter receiver in the letter storing unit, outputs the stored image and character data to the display unit in response to the display requesting signal, reads image and character data, which is selected from among the stored image and character data based on the account control signal, from the letter storing unit, and outputs the read image and character data together with a printing control signal. A printer prints letters corresponding to the data selectively read by the controller, in response to the printing control signal.
Abstract:
A direct memory access (DMA) first-in-first-out (FIFO) buffer includes two FIFO devices connected in parallel. An output multiplexer is controlled by a controller to pass to its output data provided by a selected one of the FIFO devices. Data is clocked into one FIFO device until it is full, after which data may be written from it. When data is written from a FIFO device, the FIFO device is emptied before data is again read into it. Using this arrangement, data can be read into one FIFO device whilst data is written from the other FIFO device.
Abstract:
An apparatus allowing stable and reliable voice communication between a computer and a network without generating noise due to slips of voice data is disclosed. A FIFO memory section temporarily stores voice data. A clock converter performs a clock conversion between the computer and the network according to a controlled clock signal and a network-extracted clock signal. The amount of data stored in the FIFO memory section is monitored. A frequency of the controlled clock signal is changed depending on the amount of data stored in the FIFO memory section so that the voice data is continuously transferred.
