Latest Patents
One of Bart's latest patents is titled "Utilization of Microphone Ultrasonic Response." This invention describes a system that includes a microelectromechanical system (MEMS) microphone device. The device is designed to capture signal data representing both an ultrasonic signal and an audio-band signal simultaneously. Additionally, the processing circuitry is configured to adjust a configuration parameter associated with the MEMS microphone device based on the ultrasonic signal.
Another notable patent is "Photoacoustic Gas Sensors with Improved Signal-to-Noise Ratio." This bi-directional photoacoustic gas sensor features a first photoacoustic cell, where an electromagnetic radiation source emits radiation to interact with an external gas. This interaction generates pressure waves that are detected by a MEMS diaphragm. The second photoacoustic cell has an interior volume and acoustic compliance that corresponds to the first cell. The processing circuitry within a substrate utilizes the acoustic signals received by both cells to determine a bi-directional response of the gas sensor, effectively removing noise and enhancing the sensor's signal-to-noise ratio.
