Abstract: Disclosed is a system and method for authorizing and executing safe semi-autonomous engagement of a safety critical firing device at a remote location. A Human Machine Interface at the near location has an input including a hardware safety barrier and hardware barrier communication unit with interfaces connected to a network. At the remote location, a control unit and an Robotic Operator Server are connected to a fire control system of the safety critical firing device and to the network. The Robotic Operator Server includes software for detecting and locking to a target and for providing authorization information to the Human Machine Interface, and to transfer trigger signals to the fire control system when authorization of engagement is confirmed by an operator via a control panel. The safety critical firing device is engaged if all of activation control, arming control, and trigger signals are present in the fire control system.

Abstract: A multiplexer/demultiplexer (MUX/DEMUX) system for multiplexing and demultiplexing information from a plurality of traffic channels is configured according to a Plesiochronous Digital Hierarchy (PDH) standard into a composite signal transferred to and from a telecommunciations interface. A PDH traffic interface receives PDH channel signals from a plurality of PDH channels and a bit-pipe interface receives bit-pipe traffic transported as a packet data stream. A composite signal generation module and interface then creates, outputs and receives a single composite serial data stream including, in a single composite format, information from the received PDH channel signals as well as the packet data stream. The rate of the bit-pipe traffic may be adaptively modulated as a function of the composite rate.

Abstract: The present invention discloses an arrangement providing a better utilization of the bus buffer memory in a data node, e.g. a switch. By using one scheduler on both sides of the switch and one timer for each output and input lines in an inventive way for transferring data to and from the time slot buses in the switch, the memory recourses therein are utilized in a more optimal way, also the present invention. Also, by setting up the scheduler parameters in a special way it is possible to obtain very short delays through the TDM switch. The present invention allows for both structured modus (bytes in transfer on the time slot buses are made identifiable) with constant delay and dependent timing, and for unstructured modus with minimum delay and both independent and dependent timing. This contributes to make the invention very useful and unique.

Abstract: The present invention is related to buffering between synchronous circuits communication via a global synchronous bus, and in particular an arrangement for reducing the busload in a TDM bus system by, in a preferred embodiment, introducing a local TEM data bus and an active buffer including a CPU controlled logic between the transceiver loads and the TDM bus. The active buffers in the TX and RX direction together provides a time delay for data travelling from a first local TDM bus out on the backplane TDM bus and back to a second local TDM of the exact duration of one TDM frame or an integer number of TDM frames.

Abstract: A method of regenerating a point-to-multipoint interface on a point-to-point interface in an ATM (Asynchronous Transfer Mode) network configuration is provided. It is determined from which circuit an ATM cell originated by using pre-pending byte(s) and/or user defined byte(s); individual tag(s) are assigned; and at least one tag is decoded corresponding to the point-to-multipoint address.

Abstract: In a data processing system, the effective speed of transferring data packets between a data processing unit and various other devices with different performance characteristics is improved by a data transfer method and a packing and buffering device, thus offloading the data processing unit or the various devices. FIFO buffers provide intermediate storage of transfer data, and packing and unpacking modules ensure efficient use of bus widths that are different on the data processing side and the device side. Data packet transfer control is effected using a control and status module with a common byte counter, and a direct transfer is facilitated via a supplementary direct data path between the data processing unit and other devices.
