Abstract
Abstract A system for positively identifying which one of a plurality of receptacles has received a sample is disclosed. It includes means for sequentially sensing the presence, along rows and columns, of tubes for dispensing samples. The receptacle at the intersection of the sensed row and column is the indicated one.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
118 words
A system for positively identifying which one of a plurality of receptacles, disposed in an orthogonal array of rows and columns has received a sample dispensing tube, the system comprising: first means for sensing the presence of the dispensing tube contiguous any of the rows of receptacles, second means for sensing the presence of the dispensing tube contiguous any of the columns of receptacles. means responsive to each of the first and second means for providing a signal indicative of the location of the receptacle lying at the intersection of a row and column in which the presence of a dispensing tube was sensed, thereby positively sensing the position of a receptacle associated with the sample dispenser tube.
Claim 2
Independent Claim
118 words
A system for positively identifying which one of a plurality of receptacles, disposed in an orthogonal array of rows and columns has received a sample dispensing tube, the system comprising: first means for sensing the presence of the dispensing tube contiguous any of the rows of receptacles, second means for sensing the presence of the dispensing tube contiguous any of the columns of receptacles. means responsive to each of the first and second means for providing a signal indicative of the location of the receptacle lying at the intersection of a row and column in which the presence of a dispensing tube was sensed, thereby positively sensing the position of a receptacle associated with the sample dispenser tube.
Claim 3
Dependent Claim
29 words
The system of claim 1 wherein the dispensing tubes presence is sensed only if the tube is contiguous a row or column continuously for a predetermined period of time.
Claim 4
Dependent Claim
24 words
The system of claim 2 which include means responsive to the signal for providing a visual indication of the location of the sensed receptacle.
Claim 5
Dependent Claim
38 words
The system of claim 3 wherein the first and second means each comprise a light emitting diode and a light detector positioned at opposite ends of each row and column, each light emitting diode being activated in sequence.
Claim 6
Dependent Claim
21 words
The system of claim 4 which also included means to illuminate a receptacle in which a sample is to be placed.
Claim 7
Dependent Claim
24 words
The system of claim 1 which include means responsive to the signal for providing a visual indication of the location of the sensed receptacle.
Claim 8
Dependent Claim
38 words
The system of claim 1 wherein the first and second means each comprise a light emitting diode and a light detector positioned at opposite ends of each row and column, each light emitting diode being activated in sequence.
Claim 9
Dependent Claim
21 words
The system of claim 1 which also included means to illuminate a receptacle in which a sample is to be placed.
