    摘要: A small, low-cost programmable controller is programmed with both bit-oriented and word oriented program instructions that are stored in a main memory. A microprocessor couples each program instruction to a respective interpreter routine of machine instructions stored in an interpreter memory. Bit-oriented program instructions with a common operation code but different bit-pointer codes are coupled to their own respective interpreter routines. The program instructions have operation codes and bit pointer codes that are assigned by a program panel, and are then translated by a translator PROM as they are coupled to an interpreter routine. Operand addresses are read through the translator PROM unchanged. Error-locating circuitry assists in detecting faulty chips in the main memory as the control program is executed. The hardware required to execute the control program is minimized, while the translator PROM allows the processor unit to be used with prior program panels.

    摘要: A preferred embodiment of an input module is connected through six address terminals and four data terminals to six banks of contacts. A single bank address is coupled to two latches in the module and then to two banks of contacts. A nibble of data is coupled from each of two banks of contacts to each of two corresponding data latches on the module. The sequential addressing of a low nibble bank and a high nibble bank and the latching of data therefrom is controlled by sequencing circuitry which is enabled each time a bank address is written to the module. In a second embodiment coded information is output through the six address terminals and decoded by two external decoders to multiplex 256 inputs to the processor. Such modules are particularly useful in multiplexing a large number of inputs to the processor of a programmable controller.

    摘要: An interchangeable keyboard application module is connected to a video monitor module in a computer terminal to provide sequences of processor instructions and a keyboard for performing a plurality of selectable applications. The video monitor module includes a CRT display, a serial I/O interface and a processor that processes characters received through the serial I/O interface for display on the CRT screen whether or not the application module is attached. The processor in the video monitor module detects the connection of the application module, and then selects its instructions from a memory in the application module first, to prompt the selection of a mode of operation for the terminal, and second to execute the selected mode of operation. The application module uses a plurality of keyboard overlays, each corresponding to a respective mode of operation. In a specific embodiment two of the modes of operation are programming applications related to programmable controllers.

    摘要: The integrated GPS/inertial navigation apparatus utilizes satellite signals received with two spatially-separated antennas to achieve improved heading estimates for a mobile platform. Each satellite signal comprises one or more component signals with each component signal having a different carrier frequency. The integrated GPS/inertial navigation apparatus consists of a receiver and an inertial navigation system. The receiver measures the carrier phase of each of one or more component signals of one or more satellite signals received by each of the two antennas during successive time periods of duration T.sub.p. Phase measured during a T.sub.p time period is called T.sub.p -phase. Only one component signal of one satellite signal received by one antenna is measured during any T.sub.p time period. The receiver utilizes the T.sub.p -phases of each component signal obtained during a T.sub.k time period to estimate the phase of the component signal at the end of the T.sub.k time period, the estimated phase at the end of the T.sub.k time period being called the T.sub.k -phase. The inertial navigation system, comprising inertial sensors and a digital processor, utilizes the T.sub.k -phases in determining the heading of the vehicle and the displacement of each of the two antennas from the inertial sensors of the inertial navigation system. The measured phase of a component signal is subject to error as a result of the satellite signal traversing the ionosphere. The inertial navigation system achieves more accurate estimates of heading and antenna displacements by utilizing the T.sub.k -phases in determining ionospheric corrections to phase.

    摘要: A programmable controller has a high density I/O module for interfacing eight analog input devices to a main processor module. The high density I/O module has a microcomputer for reading, storing and updating eight words of input data. The microcomputer also communicates with the main processor of the main processor module to transfer the eight words of input status data to a main memory. The main processor is programmed to communicate with the microcomputer in two alternate modes. In one mode the main processor is directed by an applications control program to individually couple words of the status data; in the other mode the main processor is directed by firmware instructions to alter the input/output scan and couple a block of input data.
