  • Acoustic sensors using microstructures tunable with energy other than acoustic energy
    Patent number: 6651504
    Abstract: A sensor for detecting acoustic energy includes a microstructure tuned to a predetermined acoustic frequency and a device for detecting movement of the microstructure. A display device is operatively linked to the movement detecting device. When acoustic energy strikes the acoustic sensor, acoustic energy having a predetermined frequency moves the microstructure, where the movement is detected by the movement detecting device.

  • Apparatus and method for detecting electromagnetic radiation using electron photoemission in a micromechanical sensor
    Patent number: 6444972
    Abstract: A micromechanical sensor and method for detecting electromagnetic radiation involve producing photoelectrons from a metal surface in contact with a semiconductor. The photoelectrons are extracted into the semiconductor, which causes photo-induced bending. The resulting bending is measured, and a signal corresponding to the measured bending is generated and processed. A plurality of individual micromechanical sensors can be arranged in a two-dimensional matrix for imaging applications.

  • Aerosol inhaler
    Patent number: 4592348
    Abstract: An aerosol dispensing device for discharging a metered amount of medication-containing aerosol into the mouth of a patient by manual compression thereof, which effectively times the release of the medication containing aerosol to coincide with the onset of inhalation of the patient to more effectively introduce the medication deeply into the patient's lungs.
