摘要： A mass sensor system including multiple Fabry-Perot microcavities connected in parallel by multiple waveguides. Each of the mass sensors includes a microbridge having a fundamental resonance frequency, and a movable reflective mirror etched into the microbridge; a fixed reflective mirror etched in a substrate, the fixed reflective mirror being fixed to the substrate in a region spaced apart from the movable reflective mirror; and an optical waveguide etched in the substrate that connects the movable mirror and the fixed mirror forming the Fabry-Perot microcavity interferometer. The system includes a tunable continuous-wave laser operative to optically interrogate the Fabry-Perot microcavity of each of the plurality of mass sensors, and a receiver operative to receive sensor signals from each of the plurality of mass sensors, the sensor signals comprising reflective signals and transmitted signals. A continuous-wave laser may generate optical forces that modify the motion, dynamics, or mechanical Q-factor of the microbridge.

摘要： Apparatus and related methods are provided for automatically recalibrating a SAW scale for changing environmental factors. During a period of time when there is no change to a weight applied to the scale, readings of SAW transducers which relate to weight indications and environmental factor indications are taken for two adjacent operating modes of the scale, and two calibrated weight calculations are made utilizing those readings. The difference in calibrated weight calculations is then related to a variable utilized to transform the readings into weights, which is updated, thereby recalibrating the scale.

摘要： A change in mass of a microbridge in a mass sensor can be sensed by applying a time-varying amplitude modulated electrostatic force to excite the microbridge into resonance at the frequency of amplitude modulation. An optical energy is then transmitted at a wavelength close to a resonant wavelength of a Fabry-Perot microcavity, which is formed by etching a movable reflective mirror into a region of the microbridge and by etching a fixed reflective minor in a region spaced apart from the microbridge. The two mirrors are interconnected by an optical waveguide. The movable mirror and fixed mirror reflect the optical energy to a receiver, and a change in the Fabry-Perot microcavity's reflectivity is interferometrically determined. The change in reflectivity indicates a change in the microbridge's resonant frequency due to increased mass of the microbridge resulting from sorption of a target chemical by a layer of chemoselective material deposited on the microbridge.

摘要： An object of the present invention is to provide a detection sensor and a vibrator which can offer improved sensitivity. The present invention uses a scheme in which no piezoelectric layer, drive electrode, or the like is provided on the surface of a vibrator 30 and in which the vibrator 30 is driven by an actuator 40 provided separately from the vibrator 30. The actuator 40 is of a cantilever type and is provided near a fixed end 30a of the vibrator 30. Vibration of the actuator 40 is transmitted to the vibrator 30 via a coupling beam 70. Thus, vibration of the vibrator 30 is prevented from being inhibited by a piezoelectric layer, a drive electrode, or the like. This improves the Q value of the vibrator 30 and thus the sensitivity of the detection sensor 10. Furthermore, if the detection sensor 10 is configured to offer a sensitivity equivalent to that of a conventional one, the size of the detection sensor 10 can be sharply reduced compared to that of the conventional one.

摘要： A planar single-piece measuring string which is designed to oscillate transversely to the plane defining its rest position has two attachment tabs, a resonating string section, two coupling sections connecting the resonating string section to the attachment tabs, and two defined nodal domains where the resonating string section meets the coupling sections. The measuring string includes at each nodal domain a pair of elastic flaps. The elastic flaps extend parallel to the resonating section and participate in the oscillation of the string. The elastic flaps are connected on one side thereof to the nodal domains and the free ends of the flaps are located at a distance opposite each other. The flaps have the same thickness as the other portions of the measuring string.

摘要： A weighing apparatus is disclosed in which the load carrier (3) is arranged immediately adjacent the console (1), whereby the length of the transmission arm (3b) between the load carrier and the measuring component is reduced to a minimum. The parallel guidance system for the vertically movable components is provided by upper and lower resilient guide members (11, 11') having parallel spaced first (11a) and second (11bb) guide arms connected at one end with the console and load carrier members, respectively, and freely suspended means (11c) connecting together the other ends of the arms, thereby to define a folded guide arrangement in which the temperature-dependent changes in lengths of the arms balance each other, whereby temperature-independent guidance is produced. Furthermore, by the use of a transmission member 3b of relatively short length, directional imbalances in the application of the weighing force upon the measurement system are avoided.

摘要： This apparatus is for use in measuring a weight, or force, and it is particularly useful as a scale. The apparatus includes a single vibrating wire and wire supports that rigidly clamp the two ends of the wire. A weight to be measured is applied to the wire in substantially the direction of its length, and the applied weight changes the tension in the wire. The apparatus includes a wire drive circuit that causes the wire to vibrate at essentially its natural resonant frequency. The frequency varies as a known cubic equation with respect to the applied weight, and a computer, operating in accordance with the equation, converts the measured frequency to a weight signal. The apparatus further includes vibration dampers and isolators for reducing the effects of sympathetic vibrations and of externally induced vibrations, and means to correct for external influences such as disturbing frequencies and ambient temperature.
