Abstract: Systems, methods and apparatus are provided through which heat produced in the patient examination space by the power used to create electromagnetic fields in an MRI/MRS system is significantly reduced by coolant carried by one of two split connected concentric coil layers of one of two of the primary gradient coils used to alter the main magnetic field. The coil carrying the coolant is made of copper tubing. The second primary gradient coil is placed between the layers of the split primary gradient coil. Adjusting the number of turns in each layer of the split primary gradient coil adjusts the heat generated. The inductances and resistances of the two primary gradient coils are balanced by adjusting the gain of the coils.

Abstract: Method and system for adaptively estimating and compensating for phase noise error in a received signal s(t;data). A plurality of transmission parameter symbol (TPS) sets, each with a representative TPS group frequency, are incorporated in the signal before transmission. Received channel response amplitudes are analyzed to select a particular TPS frequency group, and inverse Fourier transforms, N(t) and D(t), are computed for these chosen signals. A complex ratio, r(t)=N(t)/D(t), is computed and used to determine a phase angle φ(t). A phase noise error compensated, time domain signal, equal to exp{−jφ(t)}·s(t−Δt(delay);data) is provided.

Abstract: An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. The lens has a balance of oxygen permeability and ion or water permeability, with the ion or water permeability being sufficient to provide good on-eye movement, such that a good tear exchange occurs between the lens and the eye. A preferred lens is a copolymerization product of a oxyperm macromer and an ionoperm monomer. The invention encompasses extended wear contact lenses, which include a core having oxygen transmission and ion transmission pathways extending from the inner surface to the outer surface.

Abstract: Novel compounds isolated from the bile of male sea lampreys are described, in particular, 7α,12α,24-trihydroxy-5α-cholan-3-one-24-sulfate and 7α,12α-dihydroxy-5α-cholan-3-one-24-oic acid and an ELISA for detecting the compounds. The bile compounds act as pheromones which attract female sea lampreys in water to the point in the water where the compounds had been introduced. The bile compounds are useful in lamprey population management programs where it is desirable to control the locomotion and distribution of lampreys and in food operations where it enhances the efficiency of catching lampreys for food.

Abstract: The invention is a fluid ejection device, such as a printhead, that has a substrate with a first surface mating to an orifice layer, preferably through a stack of thin-film layers. The orifice layer defines a fluid chamber interfacing to an orifice opening or nozzle. The substrate has a second surface having a truncated pyramidal structure; either polyhedral or triangular ridge shaped defining an opening through the substrate to the fluid chamber. The substrate further has an ejection element, preferably disposed as a resistor in the stack of thin-film layers. When energy is transferred from the ejection element to the fluid in the fluid chamber, fluid is ejected from the orifice opening. The fluid ejection device may have one or a plurality of fluid chambers and one or a plurality of frustums of a truncated polyhedral, truncated pyramidal, truncated conical or truncated triangular cross-sectional ridge structures defining openings from the second surface of the substrate to the fluid chambers.
