System and method for object and operator profiling in an object detection system in a saw
First Claim
1. A method for operating an object detection system in a saw comprising:
- operating a motor in the saw to move an implement;
engaging, with the implement in the saw, a work piece formed from a predetermined material while operating the motor to move the implement;
recording, with a controller, a sensing signal produced in the object detection system during the engaging of the work piece and the implement;
disabling, with the controller, an implement reaction mechanism in the saw during the recording to prevent triggering of the implement reaction mechanism during the recording;
generating, with the controller, a detection profile for the material of the work piece based on the recorded sensing signal;
storing, with the controller, the detection profile in a memory in the saw; and
operating the saw and the object detection system using the detection profile with the implement reaction mechanism being enabled to distinguish between contact of the implement with a work piece formed from the predetermined material and contact of the implement with a portion of a body of an operator.

Abstract
A method for operating an object detection system in a saw produces profiles for materials used in work pieces. The method includes operating a motor in the saw to move an implement and cut a work piece formed from a predetermined material, recording, a sensing signal produced in the object detection system during contact between the work piece and the implement, generating a detection profile for the material of the work piece based on the recorded sensing signal, storing, the detection profile in a memory in the saw, and operating the saw and the object detection system using the detection profile to distinguish between contact of the implement with a work piece formed from the predetermined material and contact of the implement with a portion of a body of an operator.

5. A method for operating an object detection system in a saw comprising:
-
generating with a capacitive sensor in a predetermined contact location of the saw a capacitance signal in response to contact between the capacitive sensor a hand of an operator of the saw, the predetermined contact location including the capacitive sensor being at least one of a rip fence, a rail, or an adjustment handle in the saw that the hand of the operator contacts during operation of the saw, the predetermined contact location not being on an implement of the saw; identifying, with the controller, a capacitance level of the hand of the operator based on the capacitance signal from the capacitive sensor; modifying, with a controller, a detection threshold level for identification of contact between the operator and the implement in the saw in response to the capacitance signal from the capacitive sensor; and operating with the controller the object detection system in the saw with the modified detection threshold level for detection of contact between the hand of the operator and the implement. - View Dependent Claims (6, 7, 8, 9)
