摘要： A gyroscope includes: a support frame; a circular oscillator; a flexible support structure supporting by suspension the circular oscillator to the support frame; a drive mechanism configured to induce the circular oscillator into a two-dimensional driving oscillation; a plurality of movable sections disposed at a perimeter of the circular oscillator; a plurality of digital proximity switches, each disposed near a respective movable section and around the perimeter of the circular oscillator; and a processor. The two-dimensional driving oscillation is modified responsive to an angular rotation of the support frame and the circular oscillator. The processor is operable to determine the position of each movable section, to determine the plurality of variable oscillation parameters for each oscillation of the modified drive oscillation and to determine the angular rotation of the support frame and the circular oscillator via a parametric system identification method.

摘要： A combined autonomous underwater vehicle and buoy device that may travel underwater in a horizontal orientation as an underwater glider to a desired location and then, at the desired location, move into a vertical orientation and operate as a buoy. The combined autonomous underwater vehicle and buoy device includes an elongated device body having a ballast tank, a plurality of fins, and a deployable weight. While in water, the device body may operate the ballast tank to selectively increase its buoyancy to cause vertical descent and decrease its buoyancy to cause vertical ascent, with the fins generating lift that moves the device body horizontally from this vertical motion. To move to the vertical orientation, the device body may reposition the deployable weight to adjust the center of mass of the device body sufficiently to cause the device body to move from the horizontal orientation to the vertical orientation.

摘要： A method and system for deinterlacing. A memory receives a current input image frame and a next input image frame. A processor estimates motion between the current input image frame and the next input image frame. Based on the motion estimate, a deinterlace map is created that indicates where the current input image frame should be deinterlaced. The current input image frame is split into fields, the first frame being an odd field frame, the second frame being an even field frame. The processor interpolates missing lines in the image. Two deinterlaced frames are output, with the first deinterlaced frame being based on the odd field frame and the second deinterlaced frame being based on the even field frame.

摘要： A glass concentrator mirror assembly and a method for making same. A glass concentrator mirror assembly is configured to reflect sunlight to a receiver in a reflector assembly. The glass concentrator mirror assembly has at least one glass mirror. The at least one glass mirror has a reflective side and a back side. The glass concentrator mirror assembly also has a parabola-forming frame structure for the at least one glass mirror. The parabola-forming frame structure includes a sternum that is fixedly fastened to a spine with the at least one glass mirror therebetween. The parabola-forming frame structure facilitates a substantially parabolic curvature of the at least one glass mirror. The parabola-forming frame structure provides a substantially uniform force along a line of contact between the sternum and the at least one glass mirror.

摘要： An apparatus comprising: a solid-state series switch positioned between a transmitter's high-voltage, direct current (DC) bus and a high-voltage DC power source, wherein the series switch is configured to establish an open circuit between the transmitter and the power source upon receiving a first trip signal; a solid-state shunt switch operatively coupled in shunt between the transmitter high voltage DC bus and a ground, wherein the shunt switch is configured to provide a short-circuit path from the transmitter to ground upon receiving a second trip signal; and a controller electrically coupled to the series and shunt switches, wherein the controller is configured to generate the first and second trip signals in the event that the controller receives a trouble signal from the transmitter, and wherein the first trip signal is sent to the series switch before the second trip signal is sent to the shunt switch.

摘要： Photonic devices may include a first ring resonator and a second ring resonator located within the first ring resonator, the second ring resonator separated from and optically coupled to the first ring resonator. A waveguide structure is optically coupled to the first ring resonator and may be parallel bus waveguides optically coupled on opposite ends of the first ring resonator or a u-shaped waveguide wrapped substantially around the first ring resonator. A third ring resonator may located within the second ring resonator and may be separated from and optically coupled to the first ring resonator and the second ring resonator. A sensing medium may be disposed within the interior of the third ring resonator and optically coupled to the third ring resonator. The sensing medium is configured to undergo a change in refractive index responsive to one or more analytes bound to the sensing medium.

摘要： The present invention is a method of controlling the perforation of crystalline grains in a layer of material. The first step of the method creates at least one crystalline layer composed of multiple grains and at least one grain boundary. Next, a material covers the grain boundaries to create a protective, reinforcing coating on the crystalline layer. Finally, an etching process creates perforations in the grains while the grain boundaries are protected from etching by the coating.

摘要： The present invention is directed to a transmitter system. The system is made up of a reference clock, a differential oscillator and an edge combining power amplifier (ECPA). The clock feeds a low frequency reference signal into the differential oscillator to produce at least two low frequency outputs with opposite phases. Each low frequency output is made up of a number of low frequency subsignals equal to the number of oscillator stages. Each low frequency output is fed into a branch in the ECPA having a number of sub-branches equal to the number of oscillator stages. A processor uses an edge combining algorithm to combine these subsignals into a high frequency signal.
