Abstract: An method and apparatus for measuring gravitational force are described where at least one first radiation can be provided to at least one optomechanical oscillator, the at least one optomechanical oscillator being structured to deform under the gravitational force to cause a shift in resonance associated with the at least one optomechanical oscillator. In addition, at least one second radiation is received from the at least one optomechanical oscillator, wherein the at least one second radiation is associated with the shift in the resonance, and the shift in the resonance can be determined based on the first and second radiations.

Abstract: The present invention provides a system for use with an input signal and a clock signal. The system includes a physical random interval generator, a sampling analog-to-digital converter (ADC), a timing signal generator and a reconstructor. The physical random interval generator can generate a random output signal. The ADC can output a sampled output signal based on the input signal and the random output signal. The timing signal generator can output a timing signal based on the clock signal and the random output signal. The reconstructor can reconstruct an information signal based on the sampled output signal and the timing signal.

Abstract: Embodiments of sampling techniques for server farms are described herein. In an implementation, the sampling techniques may be performed to find a range of values, in which, a quality of service measurement belongs. Each range is thought of as a “bucket” and may include a corresponding counter that is incremented for each quality of service measurement that falls within the bucket. The countes may then be converted into measurement curves which are published at periodic intervals for examination.

Abstract: A valve comprises a valve cartridge, a valve stem and a valve seal. The valve cartridge comprises a generally cylindrical cartridge body, a bore extending longitudinally through the cartridge body, and an outlet passage and intermittent inlet passages extending through a side wall of the cartridge body to intersect the bore. The valve stem comprises an elongate body configured to slide within the bore, and a neck and a seal channel circumscribing the elongate body. The valve seal is seated within the seal channel. The valve stem slides within the bore to move the seal channel past the inlet passages. Portions of the cartridge body between the inlet passages retain the valve seal within the valve channel until the inlet passages are open to the neck. In one embodiment, the inlet passages form a crenelated edge. In another embodiment, the inlet passages form a ported end.

Abstract: An apparatus for replicating diffractive optical elements by embossing a master optical element into a photopolymer material disposed on a substrate, including a fixture for retaining, aligning, and conveying radiation to the embossing sample so that the photopolymer cures under pressure. Intermediate nickel optical elements may be used in lieu of quartz optical masters. The liquid processing techniques disclosed herein allow the replication of diffractive optics on curved substrates. This additional advantage eliminates the need for a plano optical interface further reducing the element count for a given optical system.

Abstract: The present invention discloses 1) a process for photopolymer replication on plastics, and 2) the scale-up step-and-repeat process in photopolymers. High fidelity optical element replication using a master optical element having submicron diffractive pattern feature sizes embossed into a UV curable photopolymer material for step-and-repeat "tiling" replication of the master optical element to create light weight, low cost, large area diffractive optical elements (LADOE). Furthermore, by using a chrome mask to eliminate ridge formation around a single diffractive optic element extremely narrow seams result, thereby increasing the optical fidelity of the resulting LADOE. Accordingly, each LADOE made according to the present invention is characterized by having minimum seam widths between patterns of discrete diffractive optic elements that introduce negligible optical distortion to a viewer.
