Abstract
Devices and methods are provided for selectively driving a piezo transducer to operate as a pressure pattern detector or an alarm generator. In one embodiment, there is provided a device that includes: a piezo transducer; a comparator coupled to the transducer and a reference voltage; and a pressure pattern recognition circuit coupled to a comparator output of the comparator. The pressure pattern recognition circuit may be configured to: (i) determine whether the pressure pattern satisfies a predetermined condition; and (ii) in response to the pressure pattern satisfying the predetermined condition, generate an output signal.
