Abstract: A venthole of a micromechanical device is sealed with laser irradiation. A micromechanical device has a substrate, such as silicon. The substrate has an upper surface, and defines a venthole leading to a chamber that contains a device, and a trench extending downward from the upper surface and located offset from the venthole. A laser pulse is applied to the substrate at or within the trench. This causes a portion of the substrate located below the upper surface to melt and travel laterally to close off and seal the venthole laterally from beneath the upper surface.

Abstract: A non-contact real-time monitoring system of physiological signs based on millimeter-wave radar includes a millimeter-wave radar and multiple modules for processing radar signals. The millimeter-wave radar is configured to continuously transmit electromagnetic wave signals and simultaneously receive echo signals, perform frequency mixing processing on the echo signals to obtain an intermediate frequency signal, and process the intermediate frequency signal to obtain a radar four-dimensional data matrix. Human body physiological signs are monitored by analyzing body thoracic cavity micro-motion information in signals through the modules; a target echo is processed by adopting a constant false alarm rate detection algorithm, and invalid signals are filtered. A self-adaptive range cell selection algorithm based on short-time stability of respiratory signals is adopted to capture radar echoes reflecting physiological movement.
