Abstract
Representative implementations of devices and techniques provide an improved signal receive time to a sensor component. The sensor component is enclosed within a package arranged to allow the sensor to potentially receive a signal in less time. The package may have a cavity, and the cavity may be at least partly filled with an acoustical transducer.
Claims23
An apparatus, comprising:
- an acoustic sensor;
- a controller arranged to analyze an output of the acoustic sensor and to output a signal indicating a predefined state based on the analysis;
- a molded package enclosing and integral to the acoustic sensor and the controller, the package including a cavity surrounding at least the acoustic sensor;
- and
- a transducer component within the cavity, the transducer component contacting a protective membrane of the acoustic sensor and conducting acoustic waveforms from the membrane to the acoustic sensor.
2 more elements
A system, comprising:
- a sensor module arranged to receive an acoustic waveform and to output a signal based on the waveform;
- a control module arranged to receive the signal output from the sensor module and to output a state signal indicating one of a plurality of predefined states based on the signal output from the sensor module;
- and
- a housing comprising a molded package enclosing the sensor module and the control module and including a cavity surrounding at least the sensor module, the cavity at least partly filled with an acoustical transducing medium.

A method, comprising:
- coupling an acoustic sensor to a controller arranged to analyze an output of the acoustic sensor and to output a signal indicating a predefined state based on the analysis;
- enclosing the acoustic sensor and the controller within a molded package such that the molded package is integral to at least one of the acoustic sensor and the controller;
- enclosing at least one of the acoustic sensor and the controller within a cavity of the molded package;
- and
- at least partially filling the cavity with an acoustically transducing material being a liquid and/or solid material and sealing the cavity with an acoustically transparent membrane.
2 more elements
A system, comprising:
- a microphone arranged to receive an acoustic waveform and to output a signal based on the waveform;
- a microcontroller arranged to analyze the signal output from the microphone and to output a state signal indicating one of a plurality of predefined states based on analyzing the signal output from the microphone;
- and
- a molded package integral to and enclosing the microphone and the microcontroller and including a sealed cavity surrounding at least the microphone, the sealed cavity at least partly filled with acoustical transducing media including one or more of, a liquid, and a solid medium, and sealed with an acoustically transparent membrane.
