This invention relates to a microprocessor-based medical pump with a number of manual controls. The operation of this pump requires the attachment of a magnetic label to the front of the pump. This magnetic label includes a given number of strong permanent magnets in a pre-determined configuration which indicate the pharmaceutical product type and concentration to be infused. The magnetic label also changes the visual scales around the manual controls. Hall Effect sensors read the pre-determined configuration and send the data to the microprocessor which also reads the manual controls. Using the pre-determined configuration data and the manual control data, the microprocessor determines the desired infusion parameters.

A pressure control system for controlling pressure of a fluid in a chamber includes a pressure sensor configured to measure the pressure of the fluid in the chamber, and a valve configured to control the pressure of the fluid in the chamber by regulating flow of the fluid from the chamber. The pressure control system further includes a controller. The controller is configured to estimate the volume of the chamber, and to generate a pump speed curve of the valve. The controller is further configured to monitor and modify the pump speed curve so as to maintain a slope of the pump speed curve to at least a minimum value, and to use the modified pump speed curve to adjust the position of the valve in response to pressure measurements by the pressure sensor, so as to maintain the pressure in the chamber at a desired pressure setpoint.

A valve assembly including a housing having a flow channel and an annular surface surrounding the flow channel, a slide plate movable to a closed position, and a seal ring positioned between the annular surface and the slide plate. The seal ring includes a first and second sides, a first surface extending between the first and the second sides and facing towards the annular surface of the housing, and a second surface axially spaced from the first surface and extending between the first and the second sides and facing towards the slide plate. The second surface includes a continuous annular sealing portion for contacting the slide plate when the seal ring is biased against the slide plate so that a fluid-tight seal can be formed between the continuous annular sealing portion and the slide plate, and at least one passageway positioned between the annular sealing portion and the second side.

A method of balancing a first turbomachine module (20), including along an axis of rotation a bearing plane (22) on one side and a junction plane (24) on the other, with respect to a rotor (1) including said module (20), in which an equivalent complementary module is defined such that the two modules form a rotor equivalent to said rotor by assembling along the junction plane (24), the total unbalance of said equivalent rotor and the corresponding correction to be made to said module are determined, which method includes the following steps: the concentricity deviation of the bearing (22) of the first module (20) with respect to the axis perpendicular to the junction plane (24) is determined; the theoretical geometric unbalance of said equivalent complementary module is calculated; a short journal (40) is mounted on the first module adjacent to the junction plane (24) to form a short rotor whose axis of rotation is substantially coincident with the axis of the module (20) and the unbalance of the short rotor is measured; and the total unbalance of said module is determined by adding to the unbalance of the short rotor a systematic unbalance corresponding to the geometric unbalance.

A hand held motor powered device for percutaneous thrombolysis and evacuation of a clot from a clotted arterio-venous fistula is disclosed. The percutaneous thrombectomy device is provided with a plurality of nested coaxial lubricious catheters. The multi-functional thrombectomy device can simultaneously and sequentially degrade and evacuate a blood clot from a blood vessel by multiple modalities that combines to degrade the clot by mechanical agitation, fragmentation and disruption, by peri-thrombus delivery of enzymatic fluids, by irrigation with biocompatible fluids, and by balloon displacement. The thrombectomy device further provides for balloon containment and isolation of clot debris from the general circulation, thereby minimizing the risks to a patient of embolic sequelae. There is also provided an optional steering mechanism for controlled deflection of the working end of the device.

A method of printer/copier obtaining information from printer/copier printing media is provided. The method includes placing the printing media in the printer/copier, the printer/copier sensing for identifying markings on the printing media identifying the printing media as the appropriate printing media for the printer/copier, the printer/copier determining if the printing media is the appropriate printing media for use in the printer/copier. A printer/copier system for obtaining information from printing media for use in a printer/copier is provided. The printer/copier system includes a sensor for sensing for identifying markings on the printing media identifying the printing media as the appropriate printing media for the printer/copier, and a controller for determining if the printing media is the appropriate printing media for the printer/copier.
摘要:
Systems and methods in accordance with the present invention provide for an implementation of the XQuery standard, and such an implementation will be referred to herein as an XQuery (XML Query language) implementation. An XQuery implementation can be based on a token stream representation, which allows large XML documents to be processed without having to first read the entire document. An XQuery implementation can also utilize a streaming XQuery engine. A set of algorithms and a set of rewrite rules can be used for the implementation. Given a query, a set of rules can be applied to that query to transform the query into another query. Some of these rules allow the resulting query to be streamable. In other words, a query that would otherwise require an XML document to be read into memory can now be transformed into a query that can work on an XML stream. The type system of the XQuery language can be based on XML Schema, and the basic types of XML Schema can have derived types. The XQuery programs can execute in a context comprising of variable bindings, namespaces, operators, default parameters, etc. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
