Abstract
Abstract Device for acquiring, storing and evaluating the data of a checking process, comprising a data transmitter which is located at the site of the checking process, a mobile, portable data recording and storing device and a data evaluating device. The data transmitter (1) is formed by a magnetically codeable transmitter and the data acquisition and storage device is formed by a battery-operated device (2) which responds to magnetic signals and is associated with a data evaluating circuit (3,4).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
A checking apparatus, comprising: a data transmitter forming one of a plurality of such transmitters disposed at fixed locations to be checked, each of said data transmitters having an elongated track magnetically encoded with data in a magnetically activatable form specific to the respective location and arrayed along the respective track; a portable data-acquisition device formed with a head shiftable along the tracks of said data transmitters and including: a magnetic-field generator in said head for magnetically activating the magnetic coding arrayed along each track upon shifting of said head therealong in a given direction, a code detector in said head behind said magnetic-field generator with respect to said direction for detecting the respective code, and a battery-powered electronic storage connected to said code detector for storing electrical signals represented by the code detected by said code detector; and a data-evaluating device operatively couplable with said portable data-acquisition device for transfer of data represented by the electrical signals stored in said storage for evaluating said data.
Claim 2
Dependent Claim
166 words
A checking apparatus, comprising: a data transmitter forming one of a plurality of such transmitters disposed at fixed locations to be checked, each of said data transmitters having an elongated track magnetically encoded with data in a magnetically activatable form specific to the respective location and arrayed along the respective track; a portable data-acquisition device formed with a head shiftable along the tracks of said data transmitters and including: a magnetic-field generator in said head for magnetically activating the magnetic coding arrayed along each track upon shifting of said head therealong in a given direction, a code detector in said head behind said magnetic-field generator with respect to said direction for detecting the respective code, and a battery-powered electronic storage connected to said code detector for storing electrical signals represented by the code detected by said code detector; and a data-evaluating device operatively couplable with said portable data-acquisition device for transfer of data represented by the electrical signals stored in said storage for evaluating said data.
Claim 3
Dependent Claim
40 words
The checking apparatus defined in claim 1 wherein said data transmitter comprises a bar of a nonmagnetic synthetic resin material formed with a coating which is composed at least in part of magnetizable material to form a coded layer thereon.
Claim 4
Dependent Claim
54 words
The checking apparatus defined in claim 2 wherein said bar is provided with a pair of guide grooves flanking a foil formed with said coating and said head is provided with a pair of parallel ribs engageable in said grooves for guiding movement of said head along the track formed by said data transmitter.
Claim 5
Dependent Claim
42 words
The checking apparatus defined in claim 3 wherein said data acquisition device further comprises a body containing said battery-powered electronic storage and connected with said head by a bellows forming a stiff but elastic coupling sealingly joining said head with said body.
Claim 6
Dependent Claim
31 words
The checking apparatus defined in claim 4 wherein said magnetic-field generator and said code detector are mounted on a common support which is displaceable in said head against a spring force.
Claim 7
Dependent Claim
43 words
The checking apparatus defined in claim 5 wherein said data evaluating device is formed with a recess having a configuration complementary to that of said data-acquisition device whereby said data acquisition device can be inserted in said recess for said transfer of data.
