Abstract
Some embodiments of the present invention include placing a smart device and a peripheral device in pairing mode; detecting at least one pairing motion event with a dual use piezo circuit within the peripheral device; transmitting an indication of the occurrence of the at least one pairing motion event to the smart device; receiving in the smart device the indication of the occurrence of the at least one pairing motion event in satisfaction of at least one pairing condition; and pairing the smart device with the peripheral device in response to satisfaction of the at least one pairing condition. Numerous other aspects are provided.
Claims16
A dual use piezo circuit for use in pairing two wireless devices, the dual use piezo circuit comprising:
- a microcontroller including a comparator and a digital-to-analog converter (DAC);
- and
- a piezoelectric buzzer having first and second electrodes coupled respectively to first and second input/outputs of the microcontroller, the piezoelectric buzzer functioning as both a sound transducer and a signal generating vibration/impact sensor but not concurrently;
- wherein:
- an output of the DAC is coupled to a first input of the comparator, and
- the first electrode of the piezoelectric buzzer is additionally coupled to a second input of the comparator.
