1. An activation circuit for an electronic device, comprising:

  • a first accelerometer;

    a second accelerometer which is activated upon receiving a movement signal from said first accelerometer, indicating a movement of said electronic device;

    a threshold circuit connected to an output of said second accelerometer to allow only signals generated by the second accelerometer that exceed a threshold to pass;

    an input device; and

    a monitoring circuit connected to said input device and the output of said second accelerometer, providing power to said input device when said threshold circuit passes said signal to monitoring circuit and thereafter the monitoring circuit selectively generates an activation signal to activate said electronic device to a higher power state utilizing a notable signal received from said input device.
