The present invention is particularly directed to the enabling of a refresh cycle for a dynamic memory chip at a period in the fetch cycle, for example, of a type 8085 microprocessor, when the normal timing of the chip does not permit addressing of the memory. Specifically, in the fetch cycle, a fourth clock period occurs following a memory read pulse. This fourth clock cycle is required for the application of the microprocessor, but does not involve any addressing of the memory. Accordingly, in...

In a character recognition system lines of data are stored in a line memory via a series of multiplexers. The data can originate in a controller for the system, a character reading station or other sub-systems, and is supplied to the line memory over a controller bus, a transport bus and a line memory bus, respectively. Although stored in line form, two-dimensional sub-arrays of the data in various configurations can be accessed directly by the other sub-systems of the recognition system via the...

In a character recognition system lines of data are stored in a line memory. This data is then accessed by a hardware implemented character position detector over a special line memory bus, i.e., a LM-bus. The detector searches the memory for the margins of characters and can also perform a count of the black points or character points within the margins. The position detector is activated by a system controller over a B-bus, but once started by the controller it will run on autonomously until i...

An exhaust treatment device is provided for a power system. The exhaust treatment device has an inlet module, a filter module, an outlet module, and a clamping element. The filter has a housing with at least one submerged flange. At least one of the inlet and the outlet modules also have at least one submerged flange. The clamping element is configured to engage the at least one submerged flange of the filter module and the at least one submerged flange of the at least one of the inlet and the o...

The present invention provides a multi-purpose facsimile machine which functions as either a telecopier or a photocopier, at the selection of the user. The machine, when used as a telecopier, eliminates synchronization of transmitting and receiving units by storing transmitted data in a memory prior to printing. The facsimile machine includes a linear motor for driving both a print head and scan head on a single block. The linear motor includes at least one electrical coil driven along at least ...

In a computer-implemented system for managing a database system with structured data records, two internal databases separate from one another are maintained, an interface for an input at least of parts of a structured data record into one of the databases is provided, at least one interface for communicating with an external database system is provided, in order to communicate between one of the internal databases and the external database. Initiated by inputting of a new data record into the f...

An optical plug-in connection including: an optical plug-in connector; a coupling configured to receive the plug-in connector; and locking means for locking the plug-in connector in the coupling when the plug-in connector is inserted into the coupling, wherein the locking means are designed to prevent unintentional unlocking when in a locked state.
