    Abstract: An apparatus and method for measuring a target environmental variable (TEV) that employs a film-bulk acoustic resonator with motion plate. The film-bulk acoustic resonator (FBAR) includes an acoustic reflector formed in an FBAR wafer and a surface. A first electrode is formed on the surface of the acoustic reflector and has a surface. A piezoelectric layer is formed on the surface of the first electrode and has a surface. A second electrode is formed on the surface of the piezoelectric layer. A motion plate is suspended in space at a predetermined distance relative to the surface of the second electrode and is capacitively coupled to the FBAR.

    Abstract: The external cavity laser includes a resonant cavity defined at one end by a Bragg reflector and a gain medium located in the optical cavity. Coupled to the Bragg reflector is an actuator that changes the pitch of the Bragg reflector and, hence, the wavelength at which the optical cavity is resonant. The wavelength of the light generated by the external cavity laser can therefore be tuned by a single control signal applied to the actuator.

    Abstract: A method for manufacturing refractive microlenses and other three-dimensional micromechanical structures having desired properties. At least one first micromechanical structure is formed by dispensing a first material onto a surface of a first substrate, a mold is prepared using the at least one first micromechanical structure, and at least one second micromechanical structure of a second material is molded on a surface of a second substrate using the mold. The at least one first micromechanical structure is formed of a material that is suitable to the procedure by which it is dispensed, and the at least one second micromechanical structure is formed of a material that provides desired properties.

    Abstract: Each opto-mechanical pointing device includes a housing having a base that two or more rollers extend beyond to make contact with a surface. An optical module that includes a light source and a detector track the motion of the opto-mechanical pointing device directly or indirectly. Light reflecting off markings positioned opposite of each detector is used to determine the speed and distance traveled by an opto-electrical pointing device. Alternatively, the speed and distance traveled by an opto-electrical pointing device is determined by monitoring the tilt or rotation of the opto-mechanical pointing device with respect to the surface beneath the pointing device.
