Apparatus for sealing a puncture communicating with a blood vessel includes a bioabsorbable sealing member secured to one end of a filament or other retaining member. The sealing member is delivered through the puncture into the vessel, and retracted against the wall of the vessel to provide temporary hemostasis. The sealing member is rapidly absorbed after exposure within the vessel, e.g., to an aqueous or heated physiological environment (e.g., exposure to blood or body temperature), immediately or shortly after completing a medical procedure via the puncture, e.g., within the time period that the patient is ambulatory optionally, extravascular sealing material is delivered into the puncture proximal to the sealing member. The retaining member and/or extravascular material may be bioabsorbable, being absorbed at a slower rate than the sealing member. Alternatively, the filament is removed from the puncture after hemostasis is established.

Method and apparatus for monitoring a patient having a tumor to determine perfusion tumor heterogeneity wherein a solution containing a tracer, preferably a <2>H-saline solution is infused into the patient's bloodstream at a predetermined slow rate to effect perfusion into the tumor. An MRI machine is adjusted to acquire a set of dynamic <2>H magnetic resonance images of the tumor. The <2>H-images are obtained before infusion, during infusion and post infusion. First, the obtained images are processed to quantitatively determine perfusion per voxel of the images. Next, maps of perfusion parameters are generated to indicate spatial distribution of tumor perfusion. The maps are displayed in color code and analyzed.

A novel method for retiming a portion of a media content (e.g., audio data, video data, audio and video data, etc.) in a media-editing application is provided. The media editing application includes a user interface for defining a range in order to select a portion of the media content. The media editing application performs retiming by applying a speed effect to the portion of the media content selected by the defined range. For a faster speed effect, the media editing application retimes the selected portion of the media content by sampling the media content at a faster rate. For a slower speed effect, the media editing application retimes the selected portion of the media content by sampling the content at a slower rate.

PEG and related polymer derivatives having weak, hydrolytically unstable linkages near the reactive end of the polymer are provided for conjugation to drugs, including proteins, enzymes, small molecules, and others. These derivatives provide a sufficient circulation period for a drug-PEG conjugate and then for hydrolytic breakdown of the conjugate and release of the bound molecule. In some cases, drugs that previously had reduced activity when permanently coupled to PEG can have therapeutically suitable activity when coupled to a degradable PEG in accordance with the invention. The PEG of the invention can be used to impart water solubility, size, slow rate of kidney clearance, and reduced immunogenicity to the conjugate. Controlled hydrolytic release of the bound molecule in the aqueous environment can then enhance the drug delivery system.

A method and system of reconstructing data signals from one of incomplete measurements comprising a receiver for receiving data signals, an ADC system operatively connected to the receiver that digitizes the received data signal at a slower rate than the Nyquist rate to obtain sparse measurements; first and second dictionaries comprising a plurality of time shifted responses recovered from the data signal; the first dictionary comprising time shifted versions of the previously observed data signals which are sampled at or above the Nyquist minimum sample rate; the second dictionary comprising time shifted versions are sampled below the Nyquist minimum, and at least one processor for reconstruction of the waveform signals by transforming the sub-Nyquist digitized output using the first and second dictionaries to produce the data signal.

A drip irrigation hose formed with a plurality of outlets for discharging the water at longitudinally-spaced locations along the length of the hose includes a plurality of emitter elements secured to the hose at longitudinally-spaced locations along its length to define a plurality of turbulent flow passageways each in communication with the interior of the hose for discharging water from a hose outlet at a slow rate. Each of the turbulent flow passageways is defined by a relatively elastic first material coextruded with a relatively stiff second material different from the first material, such that the relatively elastic material is pressure-deformable as compared to the relatively stiff material to change the turbulent flow of each emitter element in response to the pressure of the water in the hose at the respective emitter element.

A load balancing technology segregates various inventory types (e.g., potatoes vs. milk, vs. pretzels, vs. tissue paper, etc.) based upon how frequently they are ordered in a distribution center. Inventory types that are ordered at the slowest rate are not “replicated” over multiple pods in the distribution center. Rather, they are constrained to reside at a single pod within the distribution center. Items that are ordered somewhat more frequently than those in the slowest group are replicated in multiple pods across the distribution center. In other words, these items are separately stocked at locations on more than one pod in the distribution center. This means that a container passing through the distribution center can obtain each of the items in the second group of item types at multiple pods in the distribution center. Thus, these items do not create a bottleneck in the order fulfillment process. Inventory types in a third group, the fastest movers, are segregated from items in the first two groups. They are stored in a separate type of pod that fulfills orders even faster than the other type of pods.

A DRAM memory device includes several banks of memory cells each of which are divided into first and second sets of memory cells. The memory cells in the first set can be refreshed at a relatively slow rate to reduce the power consumed by the DRAM device. Error checking and correcting circuitry in the DRAM device corrects any data retention errors in the first set of memory cells caused by the relatively slow refresh rate. The memory cells in the second set are refreshed at a normal rate, which is fast enough that data retention errors do not occur. A mode register in the DRAM device may be programmed to select the size of the second set of memory cells.

A drip irrigation hose includes a plurality of emitter elements secured to a tube at longitudinally-spaced locations to define, with an inner surface of the tube, a plurality of labyrinths each having an inlet in communication with the interior of the tube, and an outlet in communication with a tube outlet for discharging water from the tube outlet at a slow rate. The labyrinths are defined by a continuous strip of a relatively inelastic material bonded to the inner surface of the tube, and a formation of a relatively elastic material shaped to define at least the tips of a group of teeth for each of the emitter elements producing, with the inner surface of the tube a turbulent flow passageway at each of the longitudinally spaced locations along the length of the tube. In some embodiments the drip irrigation hose is formed with a clearance between the inner surface of the tube and the teeth normally bypassing at least a part of each labyrinth in the non-pressurized condition of the tube, which clearance is closed in the pressurized condition of the tube to render the labyrinths effective to regulate the flow therethrough in response to pressure.

A multirate execution unit is capable of being operated in a plurality of modes, with the execution unit being capable of clocked at multiple different rates relative to a multithreaded issue unit such that, in applications where maximum performance is desired, the execution unit can be clocked at a rate that is faster than the clock rate for the multithreaded issue unit, and in applications where a lower power profile is desired, the execution unit can be throttled back to a slower rate to reduce the power consumption of the execution unit. When the execution unit is clocked at a faster rate than the multithreaded issue unit, the issue unit is permitted to issue more instructions per cycle than when the execution unit is throttled to the slower rate to increase overall instruction throughput.

A method and apparatus to receive and demodulate call related information, e.g., Caller ID information, in an audio codec placed on the line side and powered by current drawn from the telephone line. The audio codec includes a 1st order SIGMA/DELTA A/D converter to digitize the signal from the telephone line with SIGMA/DELTA modulation. The 1st order SIGMA/DELTA A/D converter may be a scaleable component capable of alternative operation in a 2nd order. The SIGMA/DELTA encoded digitized signal is digitally processed by a DSP including an amplifier module, a digital filter, a limit/slice module, and an FSK decoder to receive and output the call related information. Placement of the audio codec on the line side and the scaleable SIGMA/DELTA A/D converter provides significantly reduced power requirements for the audio codec, thus allowing operation from power derived from the telephone line. In another embodiment, to further reduce power consumption of the audio codec, the 1st order SIGMA/DELTA A/D converter is sampled at a slower rate than is conventional, e.g., by first dividing or otherwise providing a slower sampling clock.

A drip irrigation hose includes a tube for conducting pressurized water through its interior and formed with a plurality of outlets for emitting water at longitudinally-spaced locations along the length of the tube; and a plurality of flow-control elements fixed with respect to the inner surface of the tube at longitudinally-spaced locations thereof to define, with the inner surface, a plurality of labyrinths each having an inlet communicating with the interior of the tube and an outlet communicating with a tube outlet for emitting water there from at a slow rate. The labyrinth includes a bottom wall constructed to produce, adjacent to the bottom wall, a significant laminar flow of water in which the laminar flow decreases, and thereby turbulent flow increases, with an increase in the water pressure within the tube to thereby provide pressure-compensation for the water flow through the respective tube outlet.

The invention provides a computer implemented method to automate the calibration of the drive voltage waveform of a solenoid operated valve. An initial estimate of valve electromagnetic parameters and valve closure point is derived and the drive voltage waveform is created based in part on circuit constraints and the parameters and valve closure point. The drive voltage waveform is applied to the valve coil and the coil current feedback is obtained and used to update the initial estimate. This process is repeated until the coil current feedback meets predetermined criteria. The electromagnetic parameters include the L/R ratio of the valve during the pull-in time and decay time, the valve back emf during the pull-hold time, and the average resistance during hold when current is steady. The closure point is used to anchor the drive voltage waveform and is adjusted at a slower rate than the other parameters.

The present invention is directed to methods and systems for allocating bandwidth (or other shared resource) among multiple masters. According to an aspect of the present invention, an arbiter assigns a bucket to each CPU (or other device) where each bucket holds the credits for that CPU. Each bucket has a predetermined fill rate and a drain rate. Depending on the priority given to a particular CPU, the corresponding bucket will drain (or fill) at a particular rate. For example, CPUs with a higher priority will drain at a slower rate. For each clock tick (or other period of time) that a CPU is stalled, a number of credits is accrued. The bucket with the highest number of credits has priority and will be given access to the shared resource (e.g., DRAM, SDRAM, SRAM, EPROM, etc.).

A coform nonwoven web that contains a matrix of meltblown fibers and an absorbent material is provided. The meltblown fibers are formed from a thermoplastic composition that contains at least one propylene/α-olefin copolymer of a certain monomer content, density, melt flow rate, etc. The selection of a specific type of propylene/α-olefin copolymer provides the resulting composition with improved thermal properties for forming a coform web. For example, the thermoplastic composition crystallizes at a relatively slow rate, thereby allowing the fibers to remain slightly tacky during formation. This tackiness may provide a variety of benefits, such as enhancing the ability of the meltblown fibers to adhere to the absorbent material during formation of the coform web. In certain embodiments, the coform web may also be imparted with texture using a three-dimensional forming surface. In such embodiments, the slow crystallization rate of the meltblown fibers may increase their ability to conform to the contours of the three-dimensional forming surface. Once the fibers crystallize, however, the meltblown fibers may achieve a degree of stiffness similar to conventional polypropylene, thereby allowing them to retain their three-dimensional shape and form a highly textured surface on the coform web.
