摘要:
Systems and methods of controlling transfer of information associated with processing operations, illustratively threads, are disclosed. Instead of transferring information from all storage locations in which information associated with a processing operation is stored for use by a processor in executing the processing operation, a determination is made regarding to or from which, if any, of the storage locations information is to be transferred. Information is then transferred to or from any determined storage locations.

An under floor heating element incorporating a scrim having one or more pairs of heating and/or sensor wires arranged in a continuous pattern such that pair members are disposed in crossing relation to one another. The pair members may be cut and joined to establish electrical connections at defined crossing points to establish feedback loop circuits with a control element.

A bathtub assembly includes a tub portion having a bowl with a backrest, a right footrest, a left footrest and a right and left armrest which respectfully extends from each footrest to the backrest. The backrest is generally concave in shape and flows from a bowl bottom. Opposite the backrest is a wall which flows into the bowl bottom. The right footrest and the left footrest are convex in shape and flank the wall. The right and left armrests are generally convex in shape along the length of the bowl sidewall.

An automated laboratory system and method allow high-throughput and fully automated processing of materials, such as liquids including genetic materials. The invention includes a variety of aspects that may be combined into a single system. For example, processing may be performed by a plurality of robotic-equipped modular stations, where each modular station has its own unique environment in which processes are performed. Transport devices, such as conveyor belts, may move objects between modular stations, saving movement for robots in the modular stations. Gels used for gel electrophoresis may be extruded, thus decreasing the time needed to form such gels. Robotically-operated well forming tools allow wells to be formed in gels in a registered and accurate way.

Disclosed herein is a-variable-area or mass or area and mass ratio species transfer device, one embodiment with a plurality of species transfer masses. At least one actuator is disposed in communication with the species transfer masses, capable of selectively moving one or more of the masses independently of other one or more of the masses into at least contact with a first fluid stream and into contact with a second fluid stream. Yet further disclosed herein is a method for controlling species transfer in a species transfer device. The method includes: selecting an appropriate mass/area ratio between a portion of a variable area or mass or area and mass ratio species transfer device exposed to a higher-temperature fluid and a portion of the species transfer device exposed to a lower-temperature fluid; exposing one selected portion of the species transfer device to the higher-temperature fluid; and exposing another selected portion of the species transfer device to the lower-temperature fluid.

An apparatus for use in a cephalostat has a collimator for defining the shape of an X-ray beam and a soft tissue filter screen, mounted independently of the collimator, for attenuating a portion of the X-ray beam. The soft tissue filter screen has an anterior facial portion and a submental-neck portion having a leading edge at a position posterior relative to the leading edge of the anterior facial portion. The soft tissue filter screen is independently adjustable relative to the collimator. A cephalometric radiology apparatus includes a support structure, an X-ray source, and an X-ray detector, in addition to the collimator and the soft tissue filter screen. A method for imaging soft tissue and hard tissue involves positioning the soft tissue filter independently of positioning the collimator. A modular system, which can be mounted onto a cephalostat, includes the soft tissue filter screen and a mounting component.
摘要:
Methods directed to longest prefix matching and systems directed to IP address lookups are presented. The methods and systems relate in particular to IPv6 and comprise finding the longest prefix match (LPM) for an IP address. The method of the invention results in the use of filters to perform LPM. In embodiments of the invention, partial address filtering is used to further reduce filtering requirements. Reducing the number of filtering operations has the advantage of making the LPM algorithm faster and less costly to implement than prior art approaches. Also described is an “ideal offset filter” that extracts a fixed sized sliding window of bits from the IP address being processed.
摘要:
Parallel binary searches on lengths using hash tables is described. The parallel search uses more than one search instance. The search instances probe in parallel mutually different contiguous ranges of a search area during each round of searches. After each round, a new search area is defined and one or more search instances are redeployed into the new search area. The search instance for a range of shorter lengths can be redirected to help those of the longer lengths. Due to the help from other search instances, some ranges can be made large without sacrificing the performance. The invention realizes faster address lookups even for longer address lengths.
摘要:
Light from a small laser diode is inserted in a distal end of a catheter and passed through an optical fiber that is either included in the lumen or incorporated into the wall of an invasive catheter tube during manufacture. The light is selected to be of a wavelength that is minimally absorbed by tissue, preferably in the range from about 620 nm to 1100 nm. 780 nm is preferably used as this is where the tissue absorption is near a minimum. The light passes out the end of the fiber (at the proximal end of the catheter) and through the tissue to the outside of the patient's skin where it is measured. The light pattern is observed by night vision goggles that filter out other frequencies of light. The detected light permits location of the end of the fiber, the positional accuracy depending on the thickness of tissue between the fiber tip and the exterior of the body. The method is highly accurate for small children and for catheters within a few centimeters of the skin surface of adults.
