摘要： Methods, systems and system components for optimizing contrast resolution of an imaging or sensing system utilizing multiple channels of broadband data associated with an array of transducers. Channels or data are filtered by passing the channels of data through finite impulse response (FIR) filters on each channel. The filters each have multiple taps having tap weights pre-calculated as a function of distance of the array from an object that energy is being transmitted to or reflected from. The weights are pre-computed through a deterministic equation based on an a priori system model.

摘要： Disclosed is an ultrasonic phase aberration correction method and apparatus. One preferred embodiment employs a translating transmit aperture for transmitting two separately transmitted pulses through two different transmit apertures but which are focused to the same predetermined target in the human body. A receiver element measuring a first echo from a first transmit pulse is matched with a receiver element measuring a second echo from a second transmit pulse from a translated aperture, the match corresponding to receivers with a separation equal and opposite to the spatial translations of the translated transmit apertures. The matched elements are compared for signal variations which estimate phase aberrations and especially improve on estimates of distributed aberrations. The transmit or receive signals can then be compensated for or adjusted based on the signal comparison and variation estimates. It is also disclosed that the use of phase spectra analysis with a translating aperture improves aberration correction. Further, the use of a translating aperture with cross-correlation techniques also indicates improved correlations.

摘要： A bioabsorbable stent for placement at the locus of a stenotic portion of a body passage, such as a blood vessel, which is flexible and compliant for safe and effective delivery to the site of the stenotic portion of, for example, a blood vessel, and so as to avoid the disadvantages of chronic implantation, such as arterial rupture or aneurism formation while exposed to the continuous stresses of a beating heart. The stent is formed from a bioabsorbable material and is porous or has apertures defined there through to facilitate tissue ingrowth and encapsulation of the stent. The stent is encapsulated and biodegrades or bioabsorbs within a period of days, weeks or months as desired following encapsulation to thereby minimize the likelihood of embolization or other risks of the dissolved material and to avoid the disadvantages of chronic implantation.

摘要： Atomizing spray nozzle for mixing and atomizing various liquid and gas combinations includes a central liquid conduit, an annular gas passage disposed concentrically about the liquid conduit, a helical spray member and a spray head. The spray member includes a bore disposed in axial alignment with the liquid conduit and is of helical configuration which, in cross-section, tapers inwardly toward the distal end thereof. The spray head is of generally tubular configuration and encloses the helical member, except for at least one outlet orifice through its outer end wall. The spray head provides a chamber for the mixing of the gas and liquid and for the discharge of the resulting mixture through the orifice of the head to form an atomized spray.

摘要： A composition is disclosed for use in forming ceramic articles having improved color, density, bonding strength and mechanical strength. Ceramic particles are slurried with a composition that tends to minimize inclusion of bubbles of gas, e.g., air, and also minimize interstitial voids between the ceramic particles. In a preferred mode, the ceramic particles are slurred with an aqueous solution of sodium hydroxide having, for example, a sodium hydroxide concentration, by weight, in the order of about 0.02% to about 0.03%. The aqueous solution of the sodium hydroxide is added to a powered ceramic until a workable past or slurry is obtained. Articles are formed using the paste or slurry or the paste or slurry is built-up on a support and the ceramic is then fired to fuse the particles.
