Multi-filar, open and closed coil, tubular medical stents that are introduced to a site in a body lumen and released to expand at the site to provide a passageway through the stent lumen are disclosed. Each stent filar is a coil wound in substantially the same pitch through the majority of its length between the ends thereof. The coils are attached together at least at one coil end to form an end of the stent and wound in an interleaved manner such that the adjacent coils are substantially evenly spaced apart or in close contact in the released state and do not cross over one another. In one open coil stent embodiment, both ends of each coil are attached in respective first and second common attachment junctions, and the resulting coils have relatively even predetermined spacing between adjacent coil turns through the majority of the length of the stent between the first and last coil turns when the stent is released. Preferably, the first and second stent ends are formed by attaching the coil ends in common, and the stent ends are squared by decreasing the pitch of the first coil turn extending from the stent end such that the spacing of the stent end from the adjacent coil is reduced from the predetermined spacing. Additionally, multi-filar closed coil stent embodiments are disclosed having only one end of each coil attached in common and adjacent coil turns in substantial mutual and overlying contact in the restrained state during implantation and non-overlying contact in the released state. Preferably each common attachment junction of attached coil ends and each free coil end is formed into an enlarged stent end in at least one dimension for ease of attachment to and release from a stent delivery catheter. The common attachment junction can be snared or grasped by a stent retrieval system and retracted from the body lumen.

A system may perform interconnect BIST (IBIST) testing on source synchronous links. The system may perform, at normal operating frequency, a source synchronous link test that tests a victim line on the source synchronous link using a transition weave pattern. The transition weave pattern causes interaction between a data transition on the victim line, previous transitions on the victim line, and transitions on the other lines of the link (the “aggressor” lines). The interaction caused may be: (i) a first crossing pulse on the victim line; (ii) a second crossing pulse of the opposite polarity on each aggressor line concurrent with the first crossing pulse on the victim line; and (iii) a reflection in the opposite direction of the first transition of the first crossing pulse, wherein the reflection results from a previous transition on the victim line.

The method for detecting a pupil for iris recognition, includes the steps of: a) detecting light sources in the pupil from an eye image as two reference points; b) determining first boundary candidate points located between the iris and the pupil of the eye image, which cross over a straight line between the two reference points; c) determining second boundary candidate points located between the iris and the pupil of the eye image, which cross over a perpendicular bisector of a straight line between the first boundary candidate points; and d) determining a location and a size of the pupil by obtaining a radius of a circle and coordinates of a center of the circle based on a center candidate point, wherein the center candidate point is a center point of perpendicular bisectors of straight line between the neighbor boundary candidate points, to thereby detect the pupil.

An improved holder and method for implanting a tissue-type prosthetic mitral heart valve that prevents suture looping and may also constrict the commissure posts of the valve. An upstanding or shaft member axially positioned on the holder causes the lengths of attachment sutures to extend axially beyond the commissure post tips to create a tent and prevent looping of any of an array of pre-implanted sutures around the tips during deployment of the valve. The shaft member may be axially movable such that it can be initially retracted and then actuated just prior to valve deployment. The shaft member may have notches on its distal tip for capturing the attachment sutures, which are crossed over along the valve axis to ensure engagement by the notches. The attachment sutures may be strands or filaments, or may be wider bands of flexible biocompatible material. If bands are used, they desirably cover the commissure post tips to further help prevent suture looping thereover. The flexible lengths of material extend directly between commissures of the valve, or may extending radially inward from each commissure to a central upstanding member.

An aerial reconnaissance camera and method provides for generating a first image of the terrain of interest with the camera pointing angle oriented or rotated about an azimuthal axis some angular amount (theta1) to a first, typically forward orientation, i.e., forward of a cross-line of flight direction. An image is obtained of the ground at this orientation. Then the camera is rotated about the azimuthal axis to new angular value (theta2), which will typically be aft of the cross line of flight direction. An image is generated at this value. The camera is then rotated back to the value of theta1, and a second image in the forward orientation is generated. The camera is then rotated again to the value of theta2 and another image in the aft orientation is generated. This process of rotating the camera about the azimuthal axis and generating images in forward and aft orientations continues over and over. Eventually, as the aircraft flies past the terrain of interest, any given location in the terrain of interest will have been imaged from two different perspectives-forward and aft. The motion of the aircraft during the interim in combination with the values of theta1 and theta2 provide the high baseline for the stereo image pairs. By selection of suitable values for the angular separation of theta1 and theta2 (such as theta1=+10 degrees and theta2=-10 degrees) the result will be pairs of images of the terrain of interest having a large baseline, producing truly high aspect stereo images from a single camera. The method also works in a similar fashion by rotation back and forth about the pitch axis and imaging the terrain in forward oblique and aft oblique orientations.

An electronic system with multiple printed circuit boards interconnected through a midplane. Connectors are mounted on two sides of the midplane to facilitate connection of daughter cards from both the front and the back of the midplane. For cross-connecting coupling signals between daughter cards mounted to the front and daughter cards mounted to the back of the midplane, connectors mounted to the front and the back of the midplane are overlapped in certain regions. Within these regions, an efficient routing pattern is employed to cross-connect signals from the front of the midplane to the back of the midplane. The routing is achieved in a very small space but provides the desired impedance of the interconnects.

In a Dickson type charge pump in which a plurality of serially connected diodes sequentially respond to anti-phase 50 / 50 clock cross over or overlapped (φ1, φ2), efficiency of the charge pump is increased by providing with each diode a charge transfer transistor in parallel therewith between two adjacent nodes, and driving the charge transfer transistor to conduction during a time when the parallel diode is conducting thereby transferring any residual trapped charge at one node through the charge transfer transistor to the next node. Operating frequency can be increased by providing a pre-charge diode coupling an input node to the gate of the charge transfer transistor to facilitate conductance of the charge transfer transistor, and by coupling the control terminal of the charge transfer transistor to an input node in response to charge on an output node to thereby equalize charge on the control terminal and on the input node during a recovery period.

An improved holder, system and method for implanting a tissue-type prosthetic mitral heart valve that prevents suture looping and may also constrict the commissure posts of the valve. The holder may include two relatively movable plates, one of which attaches to the valve sewing on the inflow end of the valve ring and the other which attaches via sutures or similar expedient to the valve commissures on the outflow end. Separation of the plates places the sutures in tension and constricts the commissures. The sutures may be strands or filaments, or may be wider bands of flexible biocompatible material. If bands are used, they desirably cover the commissure post tips to further help prevent suture looping thereover. The flexible lengths of material extend directly between commissures of the valve, or may extending radially inward from each commissure to a central upstanding member. Desirably, a slide is created by the flexible lengths of material adjacent each commissure post, for example by crossing over suture filaments at or radially inward from the commissure posts. If an upstanding member is used, the lengths of suture extend axially beyond the commissure post tips to create a tent that wards off sutures that otherwise might loop around the tips during advancement of the valve along an array of pre-implanted sutures.

In another arrangement, optical blocking elements provided at the proximal end of the endoscope or within the imaging channels eliminate portions of one or more images from the imaging channels so that at the cross-over areas only a single image is provided to the imaging device.

A method and apparatus for anchoring a medical implant device after the device has been brought to rest at a desired position within a blood vessel or other body passageway. An anchor delivery system is provided which houses one or more uniquely configured expandable anchors which are connected to the medical implant device. The anchors remain housed in a non expanded configuration until after the medical implant device has come to rest in a desired position within the body, and then the anchors are positively propelled through a body wall from a first side to a second side where each anchor expands outwardly from an anchor shaft. In one configuration, the anchors are each formed in the shape of a compressible closed loop which extends outwardly from an anchor shaft and loops back to cross over and extend beyond the anchor shaft. To positively propel the anchors, a drive shaft for the anchor shafts extends back to a triggering unit which, when activated, causes the drive shaft to drive the anchor shafts in a direction which results in propulsion of the anchors through the body wall.

A route to the fabrication of electronic devices is provided, in which the devices consist of two crossed wires sandwiching an electrically addressable molecular species. The approach is extremely simple and inexpensive to implement, and scales from wire dimensions of several micrometers down to nanometer-scale dimensions. The device of the present invention can be used to produce crossbar switch arrays, logic devices, memory devices, and communication and signal routing devices. The present invention enables construction of molecular electronic devices on a length scale than can range from micrometers to nanometers via a straightforward and inexpensive chemical assembly procedure. The device is either partially or completely chemically assembled, and the key to the scaling is that the location of the devices on the substrate are defined once the devices have been assembled, not prior to assembly.

A compound bow or crossbow employs bowstring cams with bowstring cam grooves and power cord cam grooves. Preferably a pair of generally identical power cord cam grooves are positioned axially above and below the bowstring cam groove. The power cords are anchored to a fixed anchor point, e.g., a pylon, on the near end of the riser or on the near side of the crossbow bar or stock. The power cords do not cross over to the other limb. The reduction in the number of cam wheels and pulleys and in the number of strings or cords results in greater efficiency and higher transfer of energy from the bow to the arrow or bolt. There is no drop-off in pull weight at full draw. The bolt or arrow accelerates throughout the travel of the bowstring, resulting in significantly higher velocity.

An all-pass filter is cascaded with bass-management filters in at least one filter channel, and preferably all-pass filters are cascaded in each satellite speaker channel. Pole angles and magnitudes for the all-pass filters are recursively calculated to minimize phase incoherence. A step of selecting an optimal cross-over frequency may be performed in conjunction with the all-pass filtering, and is preferably used to select an optimal cross-over frequency prior to determining all-pass filter coefficients.

A holder for a prosthetic mitral heart valve that attaches to an inflow end of the valve and includes a simple tensioning mechanism that flexes the heart valve commissure posts inward to help prevent suture looping. The tensioning mechanism may include relatively movable rings of the holder or a generally unitary holder with a tensor, or rotatable knob.

A handle attaches off-center on the holder to increase visualization of and access to the heart valve through a central window. The holder is constructed of non-metallic materials so as to avoid interfering with imaging devices, and the handle is ergonomically curved and shaped to facilitate manipulation. The holder may be shaped as a ring with an open inner diameter for enhanced access to the commissure posts and leaflets.

A memory module substrate printed-circuit board (PCB) has multi-type footprints and an edge connector for mating with a memory module socket on a motherboard. Two or more kinds of dynamic-random-access memory (DRAM) chips with different data I / O widths can be soldered to solder pads around the multi-type footprints. When ×4 DRAM chips with 4 data I / O pins are soldered over the multi-type footprints, the memory module has a rank-select signal that drives chip-select inputs to all DRAM chips. When ×8 DRAM chips with 8 data I / O pins are soldered over the multi-type footprints, the memory module has two rank-select signals. One rank-select drives chip-select inputs to front-side DRAM chips while the second rank-select drives chip-select inputs to back-side DRAM chips. Wiring traces on the PCB cross-over data nibbles between the solder pads and the connector to allow two ×4 chips to drive a byte driven by only one ×8 chip.
