摘要:
A method for applying a plural-layer coating to the outside of a liquid container to act as an anti-leakage barrier in the event of a penetration wound occurring in the container resulting from a penetrating projectile strike, such as a bullet strike. This method includes (a) forming on the outside of such a container, a first layer optimized for providing an elastomeric wound-closure response, (b) forming on the outside of this first layer a second layer optimized for providing combined elastomeric and liquid-imbibing wound-closure responses, and (c) forming on the outside of such a second layer a third, layer optimized in the same manner as the first layer.

An artifact rejector for repetitive physiologic-event-signal data generated from electronically-controlled physiologic-event-measuring equipment includes a physiologic-event-signal averager in communication with such physiologic-event-measuring equipment. The artifact rejector is constructed to generate and store repetitive averaged physiologic-event-signal data based upon a substantially stable time relationship between corresponding physiologic-event-signal data and heart-beat-related-signal data. The repetitive averaged physiologic-event-signal data includes less noise than the repetitive physiologic-event-signal data. The artifact rejector generates and continuously updates an averaged-data template by storing such repetitive averaged physiologic-event-signal data for a preselected number of measured physiologic events. The artifact rejector also includes a physiologic-event-noise estimator and a physiologic-event-noise monitor in communication with such physiologic-event-measuring equipment, and capable of instructing the monitor to adjust the measurement cycle based upon estimated, monitored noise. The averager preferably includes a sharp roll-off, low pass filter and examples include a fourth-order Bessel filter, two cascaded, identical second-order Bessel filters, an elliptic filter, a Tchetschebyscheff filter, or finite impulse response filters. The heart-beat-related signal is preferably an ECG signal. A method of artifact rejection includes generating and storing repetitive averaged physiologic-event-signal data based upon a substantially stable time relationship between corresponding physiologic-event-signal data and heart-beat-related-signal data, with the repetitive averaged physiologic-event-signal data including less noise than the repetitive physiologic-event-signal data.
摘要:
A method utilizing a spray instrumentality for spray-applying to a target surface in a target zone a defined, composite-material layer which is to play a role in defeating a liquid leak from a puncture wound created in the wall of a container holding liquid of a particular character. The method includes the steps of (a) initiating a flow toward the spray instrumentality of liquid elastomeric body-forming material, (b) at a selectable point downstream from where such initiating takes place, introducing a flow of plural, bead-like, liquid-imbiber elements which are relevant to the mentioned particular-character liquid, (c) in a user-chooseable manner in relation to the introducing step, merging the two flows, and (d) following such merging, applying the merged flows to a target surface, thus to create the desired, defined composite-material layer which takes the form of a body of elastomeric material containing a distribution of liquid-imbiber elements.
摘要:
An improved method of validating pulse-like, heartbeat-induced physiologic events, such as blood-pressure pulses, is described in relation to vital signs monitoring apparatus that is also capable of monitoring R-waves obtained from an ECG sensor. The method includes the steps of monitoring the occurrence of an R-wave followed by an event of interest, and validating such event based upon analyzing, along with other preselected criteria, a time relationship extant between the R-wave and the event. The validating step includes the steps of noting the time period between selected points of the two occurrences, labeling the time period based on preselected timing criteria, and using the label with other criteria to validate the event. Events whose immediate validation is questionable are placed in a "wait and see" category for future review. The disclosed method further includes the step of repeating the monitoring, noting and labeling steps for successive R-waves and pulses, thus to establish a first measurement cycle. Also, disclosed is a step for adapting the preselected timing criteria based upon already analyzed time relationships.
