Abstract: A closure system for the electrolyte fill port of an electrochemical cell is described. A cell header has an electrolyte fill port comprising an upper opening sidewall extending from a header upper surface to an intermediate ledge located part-way through the header thickness. The ledge extends from a lower edge of the upper opening sidewall to an upper edge of a lower opening sidewall, the lower opening sidewall extending to the header lower surface.

Abstract: A fixture in which an attractive magnetic force is utilized to join two parts of a container or housing together is discussed. The fixture comprises a fixture body portion, a fixture base portion and a removable fixture plate portion. At least one body magnet resides within the fixture body portion and at least one plate magnet resides within the removable fixture plate. The fixture body and plate magnets are positioned such that when they are brought together, an attractive magnetic force pulls the plate towards the fixture body. Therefore, when the respective housing portions are positioned within the fixture, the magnetic force compresses the housing portions together.

Abstract: An electrochemical cell comprising a conductive casing housing an electrode assembly provided with a stack holder surrounding the electrode assembly is described. The stack holder is of a shape memory material that serves to maintain the anode and cathode in a face-to-face close physical proximity alignment throughout discharge. This is particularly important in later stages of cell life. As the cell discharges, anode active material is physically moved from the anode to intercalate with the cathode active material. As this mass transfer occurs, the cathode becomes physically larger and the anode smaller. This can lead to gaps forming between the anode and the cathode. However, the stack holder inhibits the formation of such gaps by maintaining a compressive force on the electrode assembly throughout cell discharge.

Abstract: Improved methods and apparatus for non-invasively assessing one or more parameters associated with fluidic systems such as the circulatory system of a living organism, when such parameters are potentially affected by other concurrent events. In one exemplary embodiment, apparatus and methods for compensating for occlusive events (e.g., pressure cuff inflation) occurring ipsilateral to the location of parameter measurement are disclosed. Upon passive detection of signal degradation resulting from the event, the apparatus selectively enters a “wait state” wherein further processing of the hemodynamic data is suspended until the degrading event subsides. This behavior mitigates any adverse effects the event might have on the accuracy of the representation of the measured hemodynamic parameter generated by the system. In another exemplary embodiment, the measured data is analyzed in order to classify the type of event (e.g.

In a first aspect, an improved method of continuously measuring pressure from a compressible vessel is disclosed, wherein a substantially optimal level of compression for the vessel is achieved and maintained using perturbations (e.g., modulation) of the compression level of the vessel. In one exemplary embodiment, the modulation is conducted according to a pseudo-random binary sequence (PBRS). In a second aspect, an improved apparatus for determining the blood pressure of a living subject is disclosed, the apparatus generally comprising a pressure sensor and associated processor with a computer program defining a plurality of operating states related to the sensed pressure data. Methods for pressure waveform correction and reacquisition, as well as treatment using the present invention, are also disclosed.
