    Abstract: A method and apparatus that projects a two-dimensional image is disclosed. The method may include emitting a laser beam, sweeping the laser beam with a first scan mirror along a first scan direction to form a scan line on the projection surface, and sweeping the scan line with a second scan mirror along a second scan direction generally orthogonal to the first scan direction to form a raster pattern of scan lines on the projection surface. The scanner for the first scan mirror is driven with a stimulus waveform, wherein the stimulus waveform has a fundamental frequency that is substantially equal to the resonance frequency of the scanner but also contains harmonics to achieve a nearly constant velocity of the laser beam spot during its scan across the projection surface. The stimulus thereby reduces peak laser output power and corresponding noise generation while maintaining image brightness and image quality.

    Abstract: A method and system for monitoring physiological parameters is useful for remote auscultation of the heart and lungs. The system includes an acoustic sensor (105) that has a stethoscopic cup (305). A membrane (325) is positioned adjacent to a first end of the stethoscopic cup (305), and an impedance matching element (335) is positioned adjacent to the membrane (325). The element (335) provides for acoustic impedance matching with a body such as a human torso. A microphone (315) is positioned near the other end of the stethoscopic cup (305) so as to detect sounds from the body. A signal-conditioning module (110) is then operatively connected to the acoustic sensor (105), and a wireless transceiver (115) is operatively connected to the signal-conditioning module (110). Auscultation can then occur at a remote facility that receives signals sent from the transceiver (115).
