Abstract
Abstract A device for the automatic and momentary electrical connection of the wires of a cable with the circuit of a memory. A sensor connects each wire of the cable with a telescopic tip and an electronic chip which connects the telescopic tips to a memory. As a button provided on the cover of the sensor is depressed, the telescopic tips pierce through a protecting film on the face of the electronic chip and provide electrical contact between the cable and the memory. The sensor and electronic chip each have a bevel gear, the teeth of which position the sensor relative to the electronic chip so that each engages an electrical contact on the surface of the electronic chip. An electronic circuit connected with the cable senses the angular position of each of the telescopic tips with reference to the electrical contacts. This device provides a momentary electrical contact with the electronic chip to read a memory or store data therein.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
A quick automatic connection device comprising: an electronic chip having a contact surface, said contact surface having a plurality of conducting areas from one another and arranged about a central axis; a sensor having a like plurality of electrically conductive tips, each engageable with one of said plurality of conducting areas when said sensor is pressed against said contact surface; alignment means for rotating said sensor with respect to said contact surface to assure each of said electrically conductive tips engage with a respective one of said conducting areas when said sensor is pressed against said contact surface independent of the rotational orientation between said sensor and said electronic chip; and electronic circuit means associated with said sensor for sensing the total rotational orientation of said sensor with respect to said electronic chip to identify the particular conducting area to which each of said plurality of electrically conductive tips is engaged.
Claim 2
Dependent Claim
151 words
A quick automatic connection device comprising: an electronic chip having a contact surface, said contact surface having a plurality of conducting areas from one another and arranged about a central axis; a sensor having a like plurality of electrically conductive tips, each engageable with one of said plurality of conducting areas when said sensor is pressed against said contact surface; alignment means for rotating said sensor with respect to said contact surface to assure each of said electrically conductive tips engage with a respective one of said conducting areas when said sensor is pressed against said contact surface independent of the rotational orientation between said sensor and said electronic chip; and electronic circuit means associated with said sensor for sensing the total rotational orientation of said sensor with respect to said electronic chip to identify the particular conducting area to which each of said plurality of electrically conductive tips is engaged.
Claim 3
Dependent Claim
56 words
A device as claimed in claim 1, wherein said electrically conductive tips of said sensor are telescopic metal pins biased outward by spring return means, so that when said sensor is pressed against said contact surface each of the said electrically conductive tips is biased by said spring return means against one of said conducting areas.
Claim 4
Dependent Claim
90 words
A device as claimed in claim 1, wherein said alignment means comprises a first gear provided on said electronic circuit means whose teeth are designed to mesh with the teeth of a mating gear provided on said sensor, and thus before said electrically conductive tips of said sensor come in contact with said conducting areas, said teeth of said first gear and said mating gear rotationally orienting said sensor with reference to said conducting areas to assure that each electrically conductive tip is aligned with one of said conducting areas.
Claim 5
Dependent Claim
19 words
A device as claimed in claim 3, wherein said teeth of said first and said mating gears are bevelled.
Claim 6
Dependent Claim
49 words
A device as claimed in claim 1, wherein said contact surface is coated with a soft, insulating and pierceable film for its protection, whereas said electrically conductive tips of said sensor are sharp enough to pierce through said film upon the pressing of said sensor against said contact surface.
Claim 7
Dependent Claim
27 words
A device as claimed in claim 1, wherein said electronic chip includes a memory having a stored content connected to said conducting areas of said contact surface.
Claim 8
Dependent Claim
66 words
A device as claimed in claim 6, wherein said electronic circuit means has an initial phase of operation during which an impedance measuring circuit scans said electrically conductive tips to determine which one of said conducting areas each of said electrically conductive tips is contacting and a subsequent operating phase allowing said stored content of said memory of said electronic chip to be read or modified.
Claim 9
Dependent Claim
36 words
A device as claimed in claim 5, wherein said soft, insulating and pierceable film protecting said contact surface is a self-healing synthetic material which seals itself after said sensor has been withdrawn from said contact surface.
