    摘要: An integrated circuit communication interface device includes data bus terminals, a serial output terminal, a serial input terminal, and an internal data bus. A data bus buffer connects the data bus terminals to the internal data bus. A transmit buffer connects the serial output terminal to the internal data bus. A receive buffer connects the serial input terminal to the internal data bus. Control circuitry controls the buffer so that the device receives or transmits data in either the Echoplex protocol or the RS 232 protocol. The device includes a data register which is programmed to select the device's mode of operation.

    摘要: The invention is a method for measuring the dimensions of a parcel through point determination which is initiated by placing a parcel on a weighing scale within a field of measurement which comprises a first known spatial relationship. In a preferred embodiment, an ultrasonic emitter is positioned at the outermost corner of the parcel. A sensor is placed on a line along each of the three axes ending at the outermost corner of the parcel; the lines representing the length, width, and height of the parcel and comprising the second known spatial relationship. The emitter transmits a pulse to the sensors. Each of the lines is then measured by determining a length of time from emission of the pulse to reception of the pulse by the sensors. The measurement data is transmitted to a data processing system which converts the time length of the pulse into a distance; a three dimensional graphical representation of the parcel, as determined by the first and second known spatial relationships, can then be displayed together with the calculated weight of the parcel. The calculated dimensions can then be transmitted to a parcel processing system. In an alternative embodiment, data points are determined by positioning an electronic pointer with respect to the parcel. Points are marked on the parcel with the pointer and are transmitted to the data processing system. A position for each of the points is recorded and plotted and the dimensions of the parcel can then be calculated and processed.

    摘要: An automated mailing system includes a postage value determining system processor, a scale for providing weight indicative signals, a keyboard for operator entry of information relating to a determination of postage, and a plurality of peripheral devices. A peripheral controller interface establishes communications links with the peripheral devices. An incompatible systems interface interconnects a serial communications bus of the system processor and the peripheral controller interface. The incompatible systems interface includes a processor programmed to receive, decode and transmit information from or to the system processor along the serial bus and load or receive information from or to the peripheral controller interface along parallel lines. The communication timing constraints of the serial communications bus for receipt of data signals by the system processor do not permit monitoring of the data transmission by the incompatible systems processor. To accommodate for such timing constraints, system clock pulses of the serial bus are employed at a flip-flop to disable the incompatible systems processor.
