US Patent:

42019087, May 6, 1980

Filed:

Apr 17, 1978

Appl. No.:

5/897005

Inventors:

Bernard A. Johnson - Deerfield IL
Frederick P. Gardner - Wonder Lake IL

Assignee:

Mangood Corporation - Chicago IL

International Classification:

G08G 1065
G06F 1548

US Classification:

235 92TC

Abstract:

A system for measurement and recording of data as to events and conditions is disclosed including a recorder unit adapted to be located at a surveillance site and connected to detectors providing successive signals responsive to successive actuations by individual events, and a portable reader instrument adapted to be connected to said recorder unit. The recorder unit has semi-conductor memory for data and for instructions of a program, and a programmable data processor operable under the control of a program of instructions stored in memory to function in a recording mode. The data processor includes an arithmetic and logic unit for performing computational and decisional processes in a sequence determined by a program to count events in response to the detector signals, and to classify and accumulate the counts as data in separate locations in semi-conductor memory for separate real time periods. The portable reader instrument has a visual display device, a recording device, and a manually operable keyboard and switches for generating display commands and read commands and for transmitting those commands to the recorder unit for reading and displaying data as derived by the data processor of the recorder unit, without interruption of the recording mode, and to display on the visual display and re-record data received from the recorder unit in the recording device of the reader instrument. The reader instrument is employed both for monitoring the operation of the recorder unit and for collecting data recorded in the semi-conductor memory of the recorder unit.

Abstract:

A batching system for operating each cycle of a batching process includes a communications bus to which are connected a basic processor, a control console, an analog/digital converter module, and an interface unit. The basic processor includes RAM memory means, PROM memory means and a central processing unit containing a microprocessor. The control console includes display means, a group of set-up pushbutton switch means, a group of operate pushbutton switch means, keyboard means having a number of pushbutton switch means each providing a different BCD signal, and switch means to activate alternatively the group of set-up pushbutton switch means or the group of operate pushbutton switch means. When the set-up pushbutton switch means are activated, the pressing of each button activates a different mode of the PROM memory means. By operating these switch means followed by operation of one or more buttons of the keyboard changes can be made in the digital information stored in the RAM memory means.
