Abstract
Abstract A measuring system includes mechanical measuring arms, adapted to engage an object to be measured, and mounted to control the positions of the vanes positioned to intercept beams of light in an optical system. The optical system includes a light beam directed to a plurality of photodetectors, whereby when the vane intercepts the light beam, the outputs of the photodetectors is a digital representation of the dimension being measured.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
A quality control apparatus comprising: a plurality of test stations, each having means for manually receiving an article of a given type and means for measuring a separate type of parameter of said article, alphanumeric indicating means, means coupled to each of said measuring means for producing digital signals corresponding to the parameter measured at the respective station, said digital signal producing means comprising a common digital signal generating means for all of said stations, control means including a program memory and connected to display instructions on said indicating means sequentially directing the insertion of an article at said station by an operator, and means connected to apply said digital signals to said indicating means for sequentially displaying data thereon corresponding to the respective parameter measured.
Claim 2
Dependent Claim
126 words
A quality control apparatus comprising: a plurality of test stations, each having means for manually receiving an article of a given type and means for measuring a separate type of parameter of said article, alphanumeric indicating means, means coupled to each of said measuring means for producing digital signals corresponding to the parameter measured at the respective station, said digital signal producing means comprising a common digital signal generating means for all of said stations, control means including a program memory and connected to display instructions on said indicating means sequentially directing the insertion of an article at said station by an operator, and means connected to apply said digital signals to said indicating means for sequentially displaying data thereon corresponding to the respective parameter measured.
Claim 3
Dependent Claim
20 words
The quality control apparatus of claim 1, wherein said measuring means comprises mechanical measuring means at each of said stations.
Claim 4
Dependent Claim
46 words
The apparatus of claim 2, wherein said program memory comprises means for directing the making of a given plurality of measurements immediately sequential to one another at each station, and means for correlating the measurements in response thereto with nominal values corresponding to the respective stations.
Claim 5
Dependent Claim
31 words
The quality control apparatus of claim 3 wherein said control means includes means for displaying data on said indicating means corresponding to the deviation of respective displayed parameters from nominal values.
Claim 6
Dependent Claim
30 words
The quality control system of claim 4, wherein said control means includes means controlling the indicating means to separately indicate excess deviation of displayed data from the corresponding measured data.
Claim 7
Dependent Claim
22 words
The quality control apparatus of claim 1, comprisng operator controllable means for initiating the application of digital signals to said indicating means.
Claim 8
Dependent Claim
23 words
The quality control apparatus of claim 1, further comprising operator controllable means for producing digital signals for identifying an article to be tested.
Claim 9
Dependent Claim
37 words
The apparatus of claim 1, further comprising a separate indicator light positioned at each of said stations, said control means comprising means for energizing a light corresponding to a station in accordance with the displayed alphanumeric instructions.
Claim 10
Dependent Claim
18 words
The quality control apparatus of claim 1, further comprising means for recording data corresponding to said displayed data.
Claim 11
Dependent Claim
16 words
The quality control apparatus of claim 1, wherein said control means comprises a central processing unit.
Claim 12
Dependent Claim
73 words
The quality control apparatus of claim 10, wherein said central processing unit has stored therein standard data corresponding to measurements of different parameters, and means for comparing said standard values with measured values for display in said alphanumeric indicating means, said quality control apparatus further comprising operator controllable switch means for selecting said standard value stored in said CPU, whereby said testing means may be employed for testing a plurality of different products.
Claim 13
Dependent Claim
38 words
The apparatus of claim 10, further comprising operator controllable keyboard means connected to said central processing unit to enable entry of determined information on said alphanumeric indicator means in response to determined instructions from said central processing unit.
