Abstract: A connector assembly for a heat exchanger has a fitting and a mount to which the fitting couples. The fitting has an elongate body having a proximal portion and a distal portion. At the proximal portion there is a crossbar, and at the distal portion there are an inlet and an outlet that protrude away from the body. Two wings extend from the body in a direction opposite to that of the inlet and outlet. There is formed on each of the wings a locking protrusion. The mount has a top portion where there is a groove dimensioned to accept the crossbar of the fitting. A longitudinal channel is formed orthogonal to the groove in the mount. Two sidewalls extend from the mount each for accepting a corresponding one of the wings, when the fitting is coupled to the mount. Apertures are provided at the sidewalls at the wings.

Abstract: An underbody convective warming blanket that may be used by a pediatric or neonate patient includes a head portion configured with multiple substantially U-shaped channels each having a plurality of adjacent rows of apertures that circumscribe the head of the patient positioned on the blanket. The adjacent rows of apertures are configured on the upper layer of the blanket so as to be positioned at an orientation or angle relative to the base plane of the blanket or the head of the patient such that those apertures would substantially face the head of the patient when the blanket is inflated, so that the heated air output from the apertures is directed substantially towards the head of the patient to thereby effect an invisible dome of heated air that envelopes the head of the patient.

Abstract: An inflatable convective thermal blanket is designed to have at least one section on its top surface that has securely mounted thereon at least one fluid absorbent mechanism for absorbing fluids from a subject that is placed onto the blanket, or from fluids fallen onto the blanket from other sources. The one section is configured onto the blanket in such a way that it forms a well for collecting the fluids. The fluid absorbent mechanism, which may be in the form of a pad, would absorb the collected fluid to thereby minimize evaporative and cooling effects on the subject. Instead of mounting it on top of the blanket, the fluid absorbent pad may be mounted to the underside of the blanket, with appropriate holes and/or openings provided at the fluid collecting section, so that the collected fluids are drained onto the fluid absorbent pad.

Abstract: A heat exchanger has a multi-lumen tubing having one end connected to a supply fitting and another end connected to a return fitting. The tubing has a central lumen, a middle lumen that surrounds the central lumen and an outer lumen that surrounds the middle lumen. The supply fitting has an inlet, an outlet and a proximal port wherethrough an infusate is input to the heat exchanger. The supply fitting is configured such that its inlet is connected to the central lumen, its outlet connected to the outer lumen, and its proximal port connected to the middle lumen of the tubing. The return fitting is configured to establish a through passage between the central lumen and the outer lumen of the tubing so that a heating fluid fed through the supply fitting to the central lumen is returned to the supply fitting by way of the outer lumen.

Abstract: The present invention extends to methods, systems, and computer program products for accessing and manipulating data in a data flow graph. A data flow graph includes one more transforms for transforming data from one or more data stores into different formats accessible to clients. Transforms can be configured to join and split data from the same or different data stores. A metadata tree logically represents the data flow graph including locations that provide output from transforms of the data flow graph. The locations can be referenced by clients to access transformed outputs. Clients can register dependencies on data at various locations and can request evaluation of the data in response to data changes at a corresponding data store. Clients can also request data changes be propagated back through the data flow graph to one or more data stores and implemented at the one or more data stores.

Abstract: The present invention comprises phasing systems and methods for software systems. In embodiments of the present invention, the phasing system comprises a multi-tiered phasing space where operations within the software system are constrained to a phase or a sub-phase. The operations execute only in the specified phase. Thus, operations that could yield improper results in large and complex software systems do not execute simultaneously but follow a certain order. The present invention also provides a data structure to introduce the phase constraints as software attributes into the software code.

Abstract: A/D converter or as a D/A converter forms a data converter embedded in a digital circuit for reconfigurable use. Conversion parameters of the data converter are controlled on a bitwise basis from a bitwise converter configuration register. For instance, output locations (i.e., time slots) of the data converter are determined by a bitwise converter configuration register, as is the selection of a D/A conversion mode or A/D conversion mode of the data converter for that particular output location, and/or the output sample length are controlled by appropriate signals from the bitwise converter configuration register. The bitwise converter configuration register also preferably configures the input source to the data converter and/or to an interface, e.g., to a parallel-to-serial, serial-to-serial, or parallel-to-parallel interface device, on a bitwise basis, to provide flexibility both in the source of the channels as well as the output location of particular channels in the data frame.
