摘要： An accelerometer without internal mechanical attachments. Three parallel cylindrical magnets are fixed within a housing. Each cylindrical magnet has a long axis extending through the housing and a cylindrical cross-section. The cylindrical cross-sections of the cylindrical magnets are organized to form a triangular formation. The magnetization of the cylindrical magnets is tangential to the triangular formation. A diamagnetic mass object levitates within the three cylindrical magnets by the magnetization of the cylindrical magnets at an equilibrium position near the center of the triangular formation and near a central axis of the three parallel cylindrical magnets when no external force is applied. Sensors detect the location of the diamagnetic mass object when the diamagnetic mass object is displaced from the equilibrium position near the center of the triangular formation and the three parallel cylindrical magnets by an external force to the housing.

摘要： Methods and systems for locating a chemical source include measuring chemical concentration with sensors at a plurality of different positions. Measurements from pairs of positions are cross-correlated to determine an average velocity vector for a group of positions. A convergence region is determined based on a plurality of average velocity vectors to determine a chemical source location.

摘要： A piezoelectronic switch device for radio frequency (RF) applications includes a piezoelectric (PE) material layer and a piezoresistive (PR) material layer separated from one another by at least one electrode, wherein an electrical resistance of the PR material layer is dependent upon an applied voltage across the PE material layer by way of an applied pressure to the PR material layer by the PE material layer; and a conductive, high yield material (C-HYM) comprising a housing that surrounds the PE material layer, the PR material layer and the at least one electrode, the C-HYM configured to mechanically transmit a displacement of the PE material layer to the PR material layer such that applied voltage across the PE material layer causes an expansion thereof and an increase the applied pressure to the PR material layer, thereby causing a decrease in the electrical resistance of the PR material layer.

摘要： A method, apparatus and system for decreasing random motions of a levitated diamagnetic cylinder is provided. Embodiments of the present invention utilizes a parallel dipole line (PDL) trap system to trap a diamagnetic object. The trap consists of a magnetic parallel dipole line system made of a pair of transversely magnetized (or diametric) cylindrical magnets. A diamagnetic object such as graphite rod can be trapped at the center. The system includes a differential photodetector pair, a differential amplifier, a differentiator, a proportional integral differential (PID) feedback controller and electrode voltage drive system. The feedback control system will minimize the speed of the trapped rod thus lowering its effective temperature. The system can be used to minimize intrinsic noise and enhance the precision in various sensing applications using a parallel dipole line trap.

摘要： A piezoelectronic transistor device includes a first piezoelectric (PE) layer, a second PE layer, and a piezoresistive (PR) layer arranged in a stacked configuration, wherein an electrical resistance of the PR layer is dependent upon an applied voltage across the first and second PE layers by an applied pressure to the PR layer by the first and second PE layers. A piezoelectronic logic device includes a first and second piezoelectric transistor (PET), wherein the first and second PE layers of the first PET have a smaller cross sectional area than those of the second PET, such that a voltage drop across the PE layers of the first PET creates a first pressure in the PR layer of the first PET that is smaller than a second pressure in the PR layer of the second PET created by the same voltage drop across the PE layers of the second PET.
