Patent ID: 7760183

Claim:
An electronic device comprising: a sensor that senses tilt of the electronic device; an integrator connected to the sensor, wherein the integrator filters signals from the sensor; a plurality of digital filters connected to the integrator, wherein the plurality of digital filters introduce a respective plurality of delays in output from the integrator, wherein the plurality of digital filters further determine whether the electronic device has tilted greater than a threshold for longer than a first time period and decide whether the electronic device has tilted greater than the threshold for longer than a second time period, wherein the second time period is longer than the first time period; and a plurality of state machines connected to the plurality of respective digital filters, wherein the plurality of state machines change a plurality of functions of an output device if the electronic device has tilted greater than the threshold for longer than the second time period and change a plurality of functions of an input device if the electronic device has tilted greater than the threshold for longer than the first time period.
