Though the initial concept of the face-mounted resonator was ahead of fabrication technology, the solidly-mounted resonator (SMR) is now a practical resonator design yielding high Qs in a space-efficient and robust mounting configuration.
A system for providing autonomous capabilities to a radio-controlled robot, comprises two communication boxes, one connected to the robot and the other connected to an operator control unit (OCU). Each communication box comprises two radios that are interoperable with preexisting data radios in the robot; a microprocessor unit; and bidirectional attenuators. The system further comprises a software application that runs on the microprocessor unit of each communications box, to integrate data into existing transmission data stream between the robot and OCU, via preexisting data radios.
A source signal is converted into a time-variant temperature field with transduction into mechanical motion. In one embodiment, the conversion of a source signal into the time-variant temperature field is provided by utilizing a micro-fabricated fast response, bolometer-type radio frequency power meter. A resonant-type micromechanical thermal actuator may be utilized for temperature read-out and demodulation.
A radar system, apparatus, and method includes at least one radar transmitter for transmitting an electromagnetic waveform; a receiving antenna comprising a plurality of receiving antenna elements and delay lines, each of the plurality of receiving antenna elements receiving the return signal operatively associated with a predetermined delay line; each delay line having a delay length which produces a different phase delay in the return signal; the different phase delays producing substantially different antenna patterns for the received signal at a given frequency; at least one processor oper
Systems and methods for remotely detecting nuclear and non-nuclear materials such as chemical agents and gas-phase explosives are disclosed. Nuclear and non-nuclear materials may be detected by transmitting electromagnetic energy toward a remote target area, collecting scattered electromagnetic energy reflected from the remote target area, analyzing an absorption spectrum of the collected scattered electromagnetic energy, and detecting a presence of at least one nuclear or non-nuclear material in the remote target area based on the analyzed absorption spectrum.
An electrostatic ohmic shunt radio frequency (RF) microeleetromechanical system (MEMS) switch and method of manufacturing includes a co-planar waveguide (CPW) transmission line comprising a plurality of slots and a plurality of pillars, wherein a space between successive ones of the plurality of pillars is defined by one of the plurality of slots; a plurality of electrodes positioned in the slots; a conductive contact beam elevated over the CPW transmission line and the plurality of electrodes; and a plurality of conductive contact dimples positioned between the conductive contact beam and the
A method of forming a device on a substrate comprising creating a depository and at least one attached capillary; the depository being of millimeter scale; providing a liquid containing particles in the range 1 nanometer to 1 millimeter; depositing into the depository the liquid containing particles which flows into at least one capillary by capillary action; evaporating the liquid such that the particles form an agglomerate beginning at the end of the at least one capillary with a substantially uniform distribution of the particles within the agglomerate; which is used to form a device.
A dynamic antenna pattern measurement method. Embodiments of the invention provide for nanosecond or better time resolution and milliradian angular resolution of the dynamic radiation pattern of an antenna under test over the predetermined solid angle scan (up to 4_ steradians) of the dynamic radiation pattern.
A phased array of Gaussian beams was used to form an annular far-field pattern as opposed to the normal peaked pattern in most phased arrays. This annular pattern arises from the radial symmetry of the polarization in each beam. Beams opposite one another in the annulus are polarized in the same direction but are 180
