    摘要： The systems and methods disclosed herein include a sensor particle for detecting the presence of a chelatable analyte, such as glucose, wherein the sensor comprises a chromophore and a fluorescent component, such as a quantum dot. The sensor particle further comprises moieties that bind both a chelatable analyte and chromophore reversibly and competitively. In the presence of the chelatable analyte, the moieties bind the analyte, and release the chromophore. The chromophore absorbs photons of one wavelength in a free state but of a different wavelength in a bound state, and is selected to operate with the fluorescent component such that the chromophore absorbs emissions of the fluorescent substance in only one of the bound and unbound states. In certain aspects, the invention comprises methods for detecting the presence of a chelatable analyte in a medium such as water, blood plasma and urine, using the sensor particles of the invention.

    摘要： An acoustic transducer (10) includes a perforated member (12); a movable diaphragm (16) spaced from the perforated member (12); spring means (54, 56, 58, 60) interconnecting the diaphragm (16) and the perforated member (12) for movably supporting the diaphragm (16) relative to the perforated member (12); a pressure equalization slot (26) for controlling the flow of fluid through the diaphragm (16), the slot (26) equalizing the pressure on opposite sides of the diaphragm (16) for defining the low frequency response; and means (32) for applying an electric field across the perforated member (12) and the diaphragm (16) for producing an output signal representative of the variation of the space between the perforated member (12) and the diaphragm (16) in response to an incident acoustic signal.

    摘要： A method for manufacturing a flexural plate wave sensor includes the steps of depositing an etch-stop layer (34) over a substrate (32), depositing a membrane layer (36) over the etch stop layer, depositing a piezoelectric layer (38) over the membrane layer, forming a first transducer (44) on the piezoelectric layer and forming a second transducer (48) on the piezoelectric layer, spaced from the first transducer. The method further includes the steps of etching a cavity (52) through the substrate, the cavity having substantially parallel interior walls (54a, 54b), removing the portion of the etch stop layer between the cavity and the membrane layer to expose a portion (53) of the membrane layer, and depositing an absorptive coating (56) on the exposed portion of the membrane layer.

    摘要： L'invention se rapporte à un gyroscope à diapason micromécanique, qui comprend une structure suspendue (14) constituée d'au moins une première et une seconde structure vibrable (38, 40). Chaque structure vibrable peut être énergisée pour vibrer latéralement, à l'intérieur d'un premier plan, le long d'un axe (42) perpendiculaire à l'axe sensible de rotation (44). Les vibrations latérales ou en plan des première et seconde structures vibrables entraînent un mouvement simultané vertical ou rotationnel d'au moins une partie de la structure suspendue au moment de la rotation angulaire du gyroscope autour de l'axe sensible de rotation. Ce mouvement vertical ou rotationnel de la sturcture suspendue est détecté par les électrodes (70, 72) et une tension proportionnelle à ce mouvement est générée pour fournir une indication de la vitesse angulaire de rotation détectée par le gyroscope.

    摘要： A motion transducer fabricated from a semiconductor material by etched exposure and release of a resiliently suspended element (16). Electrical sensing and/or torquing is applied to the suspended element (16) to produce mass or vibrational sensitivities to provide a transducer for various physical parameters. In the case of a gyroscopic transducer a mass (28) is applied to the element and may be applied in a balanced configuration on either side. The semiconductor element and electrodes (30,32) may be isolated by the use of buried PN junctions or dielectric layers, and a separately formed insulating dielectric bridge may be used to provide a support link between the suspended element (16) and the remainder of the semiconductor material. A specific crystal orientation is useful in permitting etch control in freeing the suspended element from the remainder of the material. Suspension link stress relief is provided and a waffle construction achieved in the suspended element for use in motional transduction.
