Latest Patents

Chandrasekaran's latest patents include a sensor device and microphone assembly. This invention provides methods, systems, and apparatuses for a microphone circuit. The circuit features a transducer that can sense pressure changes and generate an electrical signal with frequency components in both a first frequency range and a second frequency range that is higher than the first. Additionally, the circuit includes feedback circuitry that attenuates frequency components in the first frequency range, generating an audio signal. A feedback path circuit incorporates a low pass filter with a cut-off frequency within the first frequency range, which filters the audio signal to produce a low pass filter signal. This signal contains frequency components in the first frequency range and can be utilized to generate a low-frequency pressure signal corresponding to low-frequency pressure changes sensed by the transducer.

Another notable patent involves acoustic transducers with a low pressure zone and diaphragms equipped with a pressure sensor. These acoustic transducers are designed to generate electrical signals in response to acoustic signals. In some embodiments, the transducer features a partially evacuated hermetically sealed cavity defined by a diaphragm. The cavity maintains a pressure lower than atmospheric pressure, and a pressure sensor is coupled to the backplate to sense the pressure within the cavity.
