Abstract
Abstract Two Hall sensor devices are positioned at a predetermined angular position with respect to each other, and with respect to a distributor, by mounting a first Hall sensor in a primary carrier, forming a first alignment means at a firing point of the first Hall sensor, mounting a second Hall sensor in a secondary carrier, and forming a second alignment means in the secondary carrier at the firing point of the second Hall sensor. A third alignment means is formed in the primary carrier at the predetermined angle from the first alignment means and the secondary carrier is mounted to the primary carrier so that the second and third alignment means are aligned and the two Hall sensors provide output signals displaced by the predetermined angular rotation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
A method of positioning two Hall sensor devices at a predetermined angular position with respect to each other on a distributor, including the steps of: mounting a first Hall sensor in a primary carrier; forming a first alignment means in the primary carrier at the firing point of the first Hall sensor; mounting a second Hall sensor in a secondary carrier; forming a second alignment means in the secondary carrier at the firing point of the second Hall sensor; forming a third alignment means in the primary carrier at a predetermined angle from the first alignment means; and mounting the secondary carrier to the primary carrier so that the second and third alignment means are aligned and the first and second Hall sensors are thus positioned the predetermined angle apart to provide output signals displaced by the predetermined angular position.
Claim 2
Independent Claim
140 words
A method of positioning two Hall sensor devices at a predetermined angular position with respect to each other on a distributor, including the steps of: mounting a first Hall sensor in a primary carrier; forming a first alignment means in the primary carrier at the firing point of the first Hall sensor; mounting a second Hall sensor in a secondary carrier; forming a second alignment means in the secondary carrier at the firing point of the second Hall sensor; forming a third alignment means in the primary carrier at a predetermined angle from the first alignment means; and mounting the secondary carrier to the primary carrier so that the second and third alignment means are aligned and the first and second Hall sensors are thus positioned the predetermined angle apart to provide output signals displaced by the predetermined angular position.
Claim 3
Dependent Claim
46 words
A method of positioning two Hall sensor devices as recited in claim 1 wherein the step of forming the first alignment means includes milling a slot for mating with a mounting tang on a distributor for rotationally positioning the primary carrier with respect to a distributor.
Claim 4
Dependent Claim
34 words
A method of positioning two Hall sensor devices as recited in claim 2 wherein the step of forming the third alignment means includes milling a tang from an extending portion of the primary carrier.
Claim 5
Dependent Claim
43 words
A method of positioning two Hall sensor devices as recited in claim 3 wherein the step of forming the second alignment means includes milling a slot sized to mate with the tang for positioning the secondary carrier with respect to the primary carrier.
Claim 6
Dependent Claim
74 words
A method of positioning two Hall sensor devices as recited in claim 4 further comprising the steps of attaching the first Hall sensor to the primary carrier, the second Hall sensor to the secondary carrier, and the secondary carrier to the primary carrier and forming a reference indication on the distributor so that that entire assembly of the two Hall sensor devices can be positioned on a distributor in a predetermined desired rotational position.
Claim 7
Dependent Claim
50 words
A method of positioning two Hall sensor devices as recited in claim 5 wherein the step of forming the first alignment means includes sensing the output of the first Hall sensor in response to a changing magnetic flux so as to establish a switch point for the first Hall sensor.
Claim 8
Dependent Claim
50 words
A method of positioning two Hall sensor devices as recited in claim 6 wherein the step of forming the second alignment means includes sensing the output of the second Hall sensor in response to a changing magnetic flux so as to establish a switch point for the second Hall sensor.
