| مستخلص: | A adjustable Hall effect sensor system having a sensor positioning component is described. In one embodiment, the Hall effect sensor system is an independently adjustable sensor system, having a plurality of Hall effect sensor, wherein one Hall effect sensor may be displaced and adjusted without effecting the location of another Hall effect sensor. A sensor positioning component comprising a paddle coupled to a main body portion by a more narrow neck is described. A cam may be configured on a paddle and provide for fine tuning the position of a Hall effect sensor. In one embodiment the main body and extensions are comprised essentially of a circuit board. |

| Claim: | 1. An independently adjustable Hall effect sensor system, comprising: a sensor positioning component comprising: a main body portion; a first extended portion coupled to the main body portion by a first neck having a length that is at least twice a width dimension; a first Hall effect sensor attached to the first extended portion; a first adjustment component configured to displace said first extended portion; a second extended portion coupled to the main body portion by a second neck having a length that is at least twice a width dimension; and a second Hall effect sensor attached to the second extended portion, a second adjustment component configured to displace said second extended portion; wherein the independently adjustable Hall effect sensor system is configured for independently positioning each of said first and second Hall effect sensors, whereby displacement of the second Hall effect sensor by said second adjustment component does not affect the position of said first extended portion or said first Hall effect sensor and whereby displacement of the first Hall effect sensor by said first adjustment component does not affect the position of said second extended portion or said second Hall effect sensor. |
| Claim: | 2. The independently adjustable Hall effect sensor system of claim 1 , wherein the sensor positioning component comprises a printed circuit board. |
| Claim: | 3. The independently adjustable Hall effect sensor system of claim 1 , wherein the main body, the first and second necks and the first and second extended portions consist essentially of a printed circuit board. |
| Claim: | 4. The independently adjustable Hail effect sensor system of claim 1 , wherein the sensor positioning component comprises a flexible circuit. |
| Claim: | 5. The independently adjustable Hall effect sensor system of claim 1 , wherein at least one of the first or second adjustment components is a cam. |
| Claim: | 6. The independently adjustable Hall effect sensor system of claim 5 , wherein the cam comprises: at least one notch; a circular lobe; and an eccentric lobe, whereby rotation of the cam adjusts a position of one of said first or second Hall effect sensor. |
| Claim: | 7. The independently adjustable Hall effect sensor system of claim 5 , wherein the cam is configured to adjust a position of the first Hall sensor in an increment of no more than 0.05 mm in a rotational direction. |
| Claim: | 8. The independently adjustable Hall effect sensor system of claim 5 , wherein the cam is configured to adjust a position of the first Hall sensor a maximum displacement range of no more than 2 mm. |
| Claim: | 9. The independently adjustable Hall effect sensor system of claim 1 , wherein at least one of the first of second extended portions is a paddle. |
| Claim: | 10. The independently adjustable Hall effect sensor system of claim 1 , wherein at least one of the first or second extended portions comprises an aperture wherein the cam is configured at least partially therein. |
| Claim: | 11. The adjustable Hall effect sensor system of claim 9 , wherein the extended portion, the main body and the neck are configured out of a single piece of material. |
| Claim: | 12. The independently adjustable Hall effect sensor system of claim 1 , further comprising at least one flange, and at least one cam configured on the flange, whereby at least one of the first or second Hall effect sensors may be adjusted in position by turning the cam. |
| Claim: | 13. The independently adjustable Hall effect sensor system of claim 1 , wherein a sensor positioning component further comprises: a third extended portion coupled to the main body portion by a third neck having a length that is at least twice a width dimension; a third Hall effect sensor attached to the third extended portion; a third adjustment component configured to displace said third extended portion; and wherein displacement of the third Hall effect sensor by said third adjustment component does not affect the position of the first or second Hall effect sensors. |
| Claim: | 14. The independently adjustable Hall effect sensor system of claim 1 , wherein the independently adjustable Hall effect sensor system is coupled to a motor, and wherein the motor is configured with greater than 50 poles. |
