Abstract

A control circuit receives inputs from first and second field effect sensors.
The control circuit produces a control output only if the second field effect sensor senses proximity or touch more than a predetermined time after the first filed effect sensor senses proximity or touch.

Claims (2)

1. An electronic control circuit, comprising:
a first field effect sensor;
a second field effect sensor;
a time delay circuit;
wherein said control circuit produces a control output only when said second field effect sensor senses proximity or touch at least a predetermined time after said first field effect sensor senses touch or proximity.
2. A method for controlling an electric release mechanism, comprising the steps of:
processing an input from a first field effect sensor;
processing an input from a second field effect sensor;
producing a control output only if said input from said second field effect sensor is received more than a predetermined time after said input from said first field effect sensor.
