Abstract
Methods and apparatus for speed sensor having a first detection module with a first sensing element. The first detection module is configured to detect movement of a target during a first mode of operation and a second detection module is configured to detect movement of the target during a low power mode of operation.
Claims21
A speed sensor, comprising:
- a first detection module having a first sensing element, wherein the first detection module is configured to detect movement of a target during a first mode of operation;
- and
- a second detection module having a second sensing element, wherein the second detection module is configured to detect movement of the target during a low power mode of operation.
A method, comprising:
- employing a first sensing element in a first detection module in a speed sensor to detect movement of a target during a first mode of operation;
- and
- employing a second sensing element in a second detection module to detect movement of the target during a low power mode of operation.
A speed sensor, comprising:
- a first means for detecting movement of a target during a first mode of operation;
- and
- a second means for detecting movement of the target during a low power mode of operation.
