A stent delivery system that includes an inner member and an outer retractable sheath is operated by a handle that permits retraction of the sheath at more than one speed. The sheath may be retracted in small, incremental steps or in a single, more rapid stroke. Means are provided for releasably locking the inner member and outer sheath in a fixed position as well as to facilitate admission of liquid into the device.

A magnetic shift register utilizes a data column comprising a thin wire of magnetic material. A writing element selectively changes the direction of the magnetic moment in the magnetic domains to write the data to the data column. Associated with each domain wall are large magnetic fringing fields concentrated in a very small space. These magnetic fringing fields write to and read from the magnetic shift register. When the domain wall is moved close to another magnetic material, the fringing fields change the direction of the magnetic moment in the magnetic material, effectively “writing” to the magnetic material. A reading element similar to a tunneling junction comprises a free layer and a pinned layer of magnetic material. Fringing fields change the direction of the magnetic moment in the free layer with respect to the pinned layer, changing electrical resistance of the reading element and “reading” data stored in the magnetic shift register.

A chromatography and fluidic device with connections capable of automated component changing, diagnostic leak and current sensing. The chromatography-electrospray device contains a chromatography column, a pre-column, a spray emitter, or other fluidic component imbedded within one or more inserts. The inserts are robotically placed in receiving hardware, and a “plug and play” compression fitting connection mechanism makes the fluidic seals in an automated fashion. A plurality of sensors capable of detecting leaks is situated in the device near leak-prone regions. The electrospray emitter has a current sensing electrode in proximity of the electrospray region, capable of detecting the electrospray current. In conjunction with an electronics system, these sensors allow for system and component diagnostics. The diagnostic information may then be used for manual or automated system repair.

A Precision Optical Intracellular Near Field Imaging / Spectroscopy Technology (POINT / NANOPOINT) is a high-resolution instrument for analyzing and comparing molecular characteristics of cells. A nanosensor array is provided which is capable of imaging inner regions of living cells without destroying its natural environment and providing new information about molecular makeup of cells. The POINT probe collects data from high-resolution imagery, providing an imaging tool for investigating cells at sub-cellular and molecular levels. Data are then incorporated into a signature facilitating molecular analysis of diseases. The POINT probe non-invasively penetrates cell membranes to image insides of intact cells allowing the POINT probe to collect data without destroying cell structures. The probe provides cellular imaging to enable the viewing of both imaging and spectroscopy of internal regions of cells. The POINT system may be attached to existing microscopes to achieve a very high resolution.

A catheter assembly including a tapered steering spine having a varying stiffness along an axial length. The tapered steering spine is tailored to provide increasing flexibility from proximal to distal in a way that makes the bend radius more uniform along the length of the steering section. In one embodiment, the tapered steering spine includes structures on adjacent rings that engage with each other when the steering section is flexed to limit the minimum bend radius to a predetermined minimum and which enhances the torsional rigidity of the steering section regardless of the degree of flexure of the steering section. The limited bend radius can prevent excessive bending of components such as fiber optics. The enhanced torsional rigidity can negate the need for torque braid in the section of the catheter shaft that surrounds the tapered steering spine.

Measurements of functional, hemographic, and blood flow parameters use a multiple echo or spin echo gradient pulse sequence whereby an early echo is acquired near the beginning of the pulse sequence which avoids saturation effects and a later echo near the end of the pulse sequence which can provide information with more sensitivity to a contrast agent for a susceptibility weighted image.

Apparatus and methods for complex imaging reflectometry and refractometry using at least partially coherent light (121). Quantitative images yield spatially-dependent, local material information about a sample (128, 228) of interest. These images may provide material properties such as chemical composition, the thickness of chemical layers, dopant concentrations, mixing between layers of a sample, reactions at interfaces, etc. An incident beam (123) of VUV wavelength or shorter is scattered off of a sample (128, 228) and imaged at various angles, wavelengths, and / or polarizations. The power of beam (123) is also measured. This data is used to obtain images of a sample's absolute, spatially varying, complex reflectance or transmittance, which is then used to determine spatially-resolved, depth-dependent sample material properties.

A throttle valve opening control device for a watercraft engine includes a control section for controlling a valve drive section that drives the throttle valve based upon a signal from a remote controller operating position detecting means. The control section determines whether the operating position is in a trolling range or in a propelling range by the signal from the remote controller operating position detecting means. When the control section determines that the operating position is in the trolling range, the control section adjusts the throttle valve opening by an amount, relative to an operational amount of the remote controller, smaller than when the operating position is in the propelling range.

Disclosed herein is a method to measure and / or adjust combing resistance of fibers by using a brush, wherein the brush comprises: a brush handle; a brush head connecting to the brush handle and comprising a substrate and bristles which are mounted on the substrate, wherein a certain number of the bristles are movable; an activation means which moves the movable bristles from their original positions to different positions; wherein the brush further comprises at least one of the following: a cover for the brush head which is movable between an open position and a closed position, which internal surface can closely face to the tips of the bristles in its closed position, and which has a gap between the substrate and its side ends in its closed position; an indication to match at least one position of the movable bristles to at least one fiber type and / or at least one treatment type; or the combination thereof. By the use of the above brush device, it becomes easier to measure and / or adjust combing resistance of a variety of fiber types.

The nucleotides can then be polymerized into oligomers. The design of the oligomers will depend on the design of the overall architecture. Simple architectures may be designed by any methods. However, more complex architectures may be design using software, such as caDNAno (as described at cadnano.org / docs.html, and herein incorporated by reference), to minimize errors and time. The user may input the desired shape of the architecture into the software and once finalized, the software will provide the oligomer sequences of the bricks to create the desired architecture. The length of the oligomers may be from about 10 to about 10,000, or less than about 9,000, less than about 8,000, less than about 5,000 nucleotides in length. The length of the oligomer will be optimized for the type of architecture used.
