Filed:

May 7, 1979

Appl. No.:

6/036754

Inventors:

Gregory K. Martin - East Detroit MI
Alexander Brunner - West Bloomfield MI

Assignee:

Visual Systems Corp. - Southfield MI

International Classification:

G06M 306

US Classification:

235 92MP

Abstract:

A microfilm indexing machine for automatically generating an index for a roll of microfilm. The indexing machine can be utilized in combination with either a microfilmer equipped with blip or image count capability to generate an index while the microfilm is being created, or with a microfilm reader to generate an index for an existing roll of microfilm. The indexing machine is a microprocessor based unit that is programmed to respond to the count signals produced by the image marker on a microfilmer or the blip sensors on a microfilm reader. The microprocessor is programmed to process the count signals and automatically update the contents of one or more counters. Document identifications are made via a keyboard and are printed on a paper tape. Upon receipt of the next count signals following the entry of a document identification, the microprocessor is further programmed to print adjacent the identification information the contents of the counter(s) which corresponds to the address location of the identified document on the roll of microfilm. When the index for the entire roll has been completed, the paper tape is removed and preferably microfilmed and spliced to the beginning of the corresponding roll of microfilm.

Abstract:

A diagnostic test apparatus for simulating pin open circuit, pin short to ground and pin shorted-to-voltage fault conditions at each pin of each connector of an engine controller module (ECM). The apparatus includes a parallel port coupled to a demultiplexer circuit. The outputs of the demultiplexer circuit drive a plurality of relay drivers, which each, in turn, control independently a single relay coupled between one particular pin of an ECM connector and its associated circuit line on the vehicle wiring harness, when the apparatus is coupled in line between the ECM connector and the vehicle wiring harness. The apparatus may be controlled by an external computer such that the three above-mentioned fault conditions may be initiated automatically. The parallel port of the apparatus is connected to an external computer, preferably a personal computer, to allow the technician to initiate the fault conditions without requiring the technician to remain inside the vehicle to actuate any switches or other like devices on the apparatus 10. The apparatus thus allows three different fault conditions to be simulated at each pin of the ECM quickly and easily through the use of an external computer.
