摘要： A mass to be levitated is provided with an electrically conductive surface that is acted upon by an oscillating electrical force field generated by a plurality of charged conductive plates. The levitated mass is kept in static equilibrium in the electric field by driving the resonant circuit with an applied time varying voltage that has a frequency greater than the natural frequency of the resonant circuit. Motion of the mass is accomplished by providing actuator elements that are selectively charged to attract the mass in a given direction. Alternatively, the mass may be moved by employing a plurality of levitation control circuits that are sequentially energized.

摘要： An electrostatic microactuator for moving an optical fiber is described and includes an actuator plate with opposed major surfaces and interspersed conductive and nonconductive portions. The actuator plate is physically engaged with the optical fiber so that the fiber moves with the actuator. First and second segmented, conductive, torque stators are disposed adjacent the opposed major surfaces of the actuator plate. Multiphase circuitry is connected to segments of the torque stators for applying phased signals thereto to induce a linear actuating force in the actuator plate. The phased signals applied to the first and second torque stators are balanced so as to positionally balance the actuator plate during its travels.

摘要： An electrostatically levitated micromotor is described that includes a generally planar rotor that exhibits an axis of symmetry and includes electrically conductive portions. A balanced stator arrangement is positioned adjacent the rotor and is connected to multi-phase circuitry for enabling the rotation of the rotor about its symmetry. A plurality of levitating electrodes are positioned about the rotor and circuitry is connected thereto for forming resonant circuits that include the conductive portion of the rotor and exhibit a natural resonant frequency. A power source energizes the resonant circuits at a frequency greater than the natural frequency and thereby enables stable levitation of the rotor.

摘要： A system and method for sensing the wave impedance of a material using an RF power source with a sensor structure comprised of a metamaterial radiative filter (MRF). The wave impedance is specified or monitored by processing a differential RF signal level with an impedance calculator. The differential RF signal level is obtained from a reference source signal and a response signal. RF field-coupling of the RF source with the material effects the response signal level. In embodiments, the spectrometer is physically configured for noninvasive and invasive measurements. In embodiments, the material is sensed when shielded by RF-opaque media. In embodiments, wherein the MRF has a fixed response characteristic, the dielectric constant may be obtained with a sensing structure comprised of two transponders and a single RF frequency. In embodiments wherein the MRF has a fixed response characteristic, both the dielectric constant and the loss tangent may be obtained using three transponders and a single RF frequency. In embodiments wherein the MRF is tuned with programmed control, both the dielectric constant and the loss tangent may be obtained using two transponders and a single RF frequency.

摘要： An “integrated” Fabry-Perot interferometer, such as for use in a spectrophotometer, is fabricated by attaching two micro-machined semiconductor-on-insulator wafers to one another. One mirror is formed on each micro-machined wafer. One mirror is supported by a thermally insulated, suspended micro-platform. In some embodiments, interferometer cavity length is adjustable. Detectors are disposed at least partially within the micro-platform. In some embodiments, the interferometer, a light source, and other circuitry and components, such as wireless communications components, are contained in a sealed package that includes a sampling region, thereby providing an integrated spectrophotometer. The integrated spectrophotometer can be implanted, for example, in animal tissue environments, such as for analyzing various compounds in the blood.

摘要： An RFID antenna comprised of a first arm, load element, and second arm together providing a complex impedance match to one or more load circuits contained within the load element for operation at one or more frequency bands. The load element is comprised of one or more load circuits. Load circuits are further comprised of one or more RFID transponders, energy scavengers, microcontrollers, and associated sensor circuits. The first and second arms are different in length and shape resulting in an asymmetrical antenna structure along the major axis. The first arm, the load element, and the second arm all comprise radiative electromagnetic structures for ultra high frequency and higher bands of operation. Embodiments provide an antenna with Faraday coils located within the arms operating in one or more of low frequency and, high frequency bands.

摘要： A Radio-Frequency IDentification (RFID) receiver is disclosed that comprises a plurality of resonant structures arranged to form an antenna. The resonant structures are interconnected in series and are arranged, relative to one another, so as to achieve a received electrical signal with an increased voltage, when the antenna is exposed to an incident electromagnetic signal. This occurs for a majority of all possible incident electromagnetic signals and, therefore, an RFID receiver based on such an antenna provides, in a majority of cases, an improved performance.
