Abstract: Embodiments are directed to a fluid-emission device. An example fluid-emission device includes a tubular body, a fluid-source coupler, and a tip member disposed opposite the tubular body from the fluid-source coupler. A fluid-transmission lumen in the tubular body fluidly couples the tip member to the fluid-source coupler. The tip member includes a plate having a plurality of fluid-emission lumens that fluidly couple the fluid-transmission lumen to an environment outside the tubular body. The tip member includes a spearhead disposed opposite the plate from the fluid-transmission lumen. The tip member has a spacer disposed between the plate and the spearhead to separate the spearhead from the fluid-emission lumens. The fluid-emission device can be used by inserting the tip member into material and delivering fluid to a target, such as delivering water or fertilizer to plant roots or the like.

Abstract: A semiconductor integrated circuit for processing content data by encrypting or decrypting the data has one or more inputs to received content and metadata. A metadata store comprises two portions, a first portion for storing metadata itself and a second portion for storing an address of locations of bitfields of metadata. This arrangement allows for efficient storage of the metadata but requires certain rules to ensure that bitfields of metadata cannot be stored and used with anything other than the content with which the metadata is associated.

Abstract: A system and method of food preparation is provided. A tool for manipulating and shaping food products, such as ground meats, is provided with specific structural features for applying a force to a raw food product. Methods of using the same are provided.

Abstract: The invention relates to a method of producing a preform for a holey optical fiber, and more particularly, to a method of producing polymer holey optical fiber using novel capillary and cane designs that allow a construction of complex holey structures. The capillaries may have a complex internal structure including multiple holes, holes of non-circular shape, off-center holes, holes of different sizes, or any combination of these. The canes may have a complex external shape to define interstitial holes when the canes arc combined in a stack (see FIG. 1). The capillaries and canes may be made of different materials and combined within the same structure.

Abstract: In a method for measuring a dimension or angle of a scattering feature of an optical device, such as a photonic crystal, at least part of the array is irradiated with light. A characteristic of light scattered from the array is detected. A comparison algorithm is run on the detected characteristic of the scattered light. The comparison algorithm provides one or more numerical values indicative of the measured dimension or angle. A system for measuring a dimension or angle of a feature of an optical device includes a light source and optics for focusing light from the light source onto a target area of the optical device. A light detector is positioned to detect scattered light from the target area, with the detected light used to create a measured light characteristic. A computer linked to the light detector performs a comparison algorithm on the measured light characteristic and outputs a numerical value of the dimension or angle measured.

Abstract: A clock source selector for selecting either a first clock signal A or a second clock signal B in accordance with a switch request signal includes three retiming circuits each consisting of two clocked flip-flops. The switch request signal is first retimed relative to clock A to give a signal P, is then retimed relative to clock B to give a signal Q, and finally is retimed relative to clock A to give a signal R. Selector circuitry operates such that when signal Q is asserted, the second clock signal B is output, when neither signal P nor signal R, as combined by a NOR gate, are asserted, the first clock signal A is output, and at other times a zero level is output. The clock source selector can be used in an integrated circuit to form a glitch-free multiplexer.

Abstract: Disclosed is a method for alleviating the oxidative impairment of vascular function by inhibiting the activity of xanthine oxidase, or active forms thereof. Xanthine oxidase levels have been shown to be increased by a variety of conditions, including sickle cell disease. In the present disclosure, allopurinol is used to inhibit xanthine oxidase activity. As a result of the inhibition of xanthine oxidase, .NO levels in a subject can be maintained. In addition to sickle cell disease, allopurinol inhibition of xanthine oxidase may be used to treat other conditions, including, but not limited to, respiratory distress, kidney disease, liver disease, ischemia-reperfusion injury, organ transplant, sepsis, burns, viral infections and hemorrhagic shock.
