A medical device communication method that may be implemented within a variety of medical devices including but not limited to infusion pumps. The method may be implemented with a protocol stack for at least intra-device communication. Embodiments provide connection-oriented, connectionless-oriented, broadcast and multicast data exchange with priority handling of data, fragmentation, and reassembly of data, unique static and dynamic address assignment and hot swap capability for connected peripherals or subsystems.

A battery management system is disclosed for control of individual cells in a battery string. The battery management system includes a charger, a voltmeter, a selection circuit and a microprocessor. Under control of the microprocessor, the selection circuit connects each cell of the battery string to the charger and voltmeter. Information relating to battery performance is recorded and analyzed. The analysis depends upon the conditions under which the battery is operating. By monitoring the battery performance under different conditions, problems with individual cells can be determined and corrected.

An injector and deposition chamber for delivering gases to a substrate or wafer for processing of said substrate or wafer is provided. The injector is provided comprising an elongated member with end surfaces and at least one gas delivery surface extending along the length of the member and which includes a number of first elongated passages formed therein for received a gas. The gas delivery surface contains rounded side regions and a center recessed region. Also formed within the member are a number of thin distribution channels which extend between the first elongated passages and the center recessed region of the gas delivery surface. In another embodiment, the injector further includes at least one second elongated passage formed therein for receiving an etchant species. The etchant species is conveyed via at least one thin distribution channel which extends between the second elongated passage and one of the rounded side regions of the gas delivery surface. Metering tubes may be inserted into each elongated passage and are spaced from the walls of said passages and extend between the ends. The deposition chamber includes at least one injector as described above; a plurality of vent blocks having end surfaces and at least one elongated external surface extending along the length of each of the vent blocks; and a support positioned beneath the injector and vent blocks, creating a deposition region therebetween. The vent blocks are positioned adjacent one on each side of the injector, and spaced from the injector to define exhaust channels therebetween for removing the gas.

Water treatment systems and methods are provided to minimize membrane fouling and the required maintenance that results therefrom. A water treatment system includes a pressure vessel with a plurality of spaced-apart membranes disposed therein, and an impeller or other means for circulating feed water through the interior of the vessel and past the membranes. Antifouling particles (such as diatomaceous earth or activated carbon) and / or pellets can be added to the feed water inhibit membrane fouling and extend the useful life of the membranes.

A system for managing and reporting laboratory data wherein the data is obtained at remote data-taking stations, transferred instantaneously by wireless communication to a main data-storing / manipulating station for recording therein without being recorded at the remote data-taking stations, and reported only from the data-storing / manipulating.

A micro-fluid ejection head has fluid ejection elements formed as thin film layers on a substrate. Fluid flow features on the substrate channel fluid from a fluid source to ejection chambers surrounding the ejection elements. A pump on the substrate circulates the fluid from the source to the ejection chambers and back again to the source. The flow refreshes the fluid in the chambers to minimize deleterious effects of evaporation. A controller coordinates the flow rate of the pump and other variables to optimize system productivity. Other embodiments contemplate pump locations, pump types, pump enumeration, and fluidic features, such as pathways, diffusers, chokes and dimensions, to name a few.

A Bi-directional rack assembly that rotates one column of threaded cores and unscrews threaded closures while moving in the forward direction. The Bi-directional rack then mechanically changes position to engage an adjacent column of rotating threaded cores and at the end of a second molding cycle rotates the threaded cores and unscrew threaded closures while moving in the reverse (reset) direction. A set of timed-advance devices are engaged by a smaller pinion gear and idler gear assemblies to the Bi-directional rack and as the Timed-Advance devices are activated, they allow pneumatic pistons to advance the stripper plate in time with the threaded closures as they are being unscrewed from the threaded cores. A second “rapid advance” pneumatic piston eliminates the need for an external rapid rise camming feature. A rotating core comprising a stock, rotating core, a stock water-seal insert and a custom core top.
