| Number | Title | Issue Date |
| 4608663 | Computer network for using a common peripheral device A non-random network can connect a common peripheral device to one of a plurality of computers. Each of these computers has a request line for providing a request signal. The network has a plurality of switching devices, each coupled to the common periphe... | 08/26/1986 |
| 4598363 | Adaptive delayed polling of sensors Apparatus (100) and a method (5) are used for polling asynchronous sensors (1, 2, 3) of a computer system to optimize the data load offered by the sensors to a central processor (4). The polling apparatus and method operate in accordance with time delay s... | 07/01/1986 |
| 4494194 | Line support processor for data transfer system Data transfers between remote data sets, data terminals and a main host computer are controlled by a peripheral-controller designated as a Line Support Processor (LSP). The LSP manages a plurality of line adapters, each of which handles a separate data co... | 01/15/1985 |
| 4466062 | Apparatus for CCIS data transfer between a CPU and a plurality of data terminal equipment A single CCIS central processing unit is employed to receive and transmit CCIS data from a central switching office to other CCIS offices via modems, or digital trunk units and T1 spans. This apparatus facilitates orderly and timely data exchange between ... | 08/14/1984 |
| 4463421 | Serial/parallel input/output bus for microprocessor system A single-chip microprocessor device of the MOS/LSI type contains an ALU, several internal busses, a number of address/data registers, and an instruction register with associated control decode or microcontrol generator circuitry. The device communicates w... | 07/31/1984 |
| 4177512 | Soft input/output auto poll system A system for automatically polling peripherals associated with a computer system employing a program controlled interrupt mechanism wherein a number of programmatically established descriptors control input/output operations. Two such descriptors, one dic... | 12/04/1979 |
| 4071908 | Adaptive polling technique Messages are collected by a central polling station from a plurality of remote terminal stations on a multiparty line. The central polling station is arranged to initially query stations in groups, probing successively smaller size subgroups of each group... | 01/31/1978 |
| 4047158 | Peripheral processing system A medium capacity peripheral processing system provides sophisticated interactive human communication without the extremely large, expensive memory systems that are normally associated with a main frame computer. The system includes a data bus interconnec... | 09/06/1977 |
| 4047159 | Data transmission systems A data transmission system for interfacing a computer with a plurality of data sources which are in groups, each group at an individual remote location, comprising local interface apparatus for the computer and remote interface apparatus for each remote l... | 09/06/1977 |
