Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Abstract: A partial body plethysmograph is provided to enable accurate modeling of a human's respiratory system for input frequencies of up to about 96 Hz using transfer impedance measurements. One preferred embodiment comprises a container for sealingly enclosing a portion of the subject's body, a pressure source for generating pressure signals over a predetermined frequency range, an air flow sensor for measuring the flow of air supplied to the subject, a pressure sensor for measuring the pressure applied to the cavity of the subject and a processor for controlling the pressure source, for storing the measured air flow and pressure and for determining the respiratory system impedance of the subject. An eight element model is used by the processor to inversely model the transfer impedance data and thereby determined characteristics of the respiratory system of the subject.

Abstract: An infant respiratory impedance measuring apparatus and method using forced oscillations is disclosed. In order to account for the effects of the mask, a shunt compliance is placed in parallel with the components representing the impedance of the infant.

Abstract: This invention relates to an acoustic pulse response system for determining the shape of the nasopharyngeal cavity in a subject by introducing an acoustic impulse through a wave tube into the respective nasal cavities of the subject. The acoustic signals and acoustic reflections thereof with respect to each one of said nasal cavities with both open and closed velums are detected by a microphone located in a wall of the tube, the microphone generating electrical signals proportional to both the impulse and acoustic reflections. The length of the nasal septum is determined, and the value of the area-distance function of the nasopharyngeal cavity is computed from the electrical signals and the length of the nasal septum.

Abstract: An optical recording element comprising a substrate and as a recording medium a layer comprising a dye having a nucleus of general formula (I): ##STR1## wherein: each Y and Z is independently selected from the group consisting of hydrogen and --XR wherein X is selected from the group consisting of S, Se and Te and R represents an organic radical; with the proviso that one and only one of Y and Z on each phenyl ring must be other than H, andM is selected from the group consisting of two hydrogen atoms, metals and metal oxides.

Abstract: A polymeric tetra-aryl polymethine dye of the general formula ##STR1## in which: A comprises a conjugated chain of carbon atoms having an equal number of double and single bonds,each R independently represents an alkyl group of 1 to 4 carbon atomsR.sup.1 represents --NR.sub.2 or ##STR2## and X.sup.- represents an anion.The dyes are suitable for use as recording media in optical recording elements in which information may be recorded and read directly afterwards by means of laser light.

Abstract: For supporting a drawer in a filing cabinet an inner runner runs on three sets of balls within an outer runner. The balls are supported by a cage. The three sets of balls are in a triangular disposition and the inner runner has lobes extending across the sides of the triangle between the balls and a stem which passes between the balls and emerges through a slot between edges of the outer channel-section runner.

Abstract: Apparatus for measuring gas volume delivered at rapidly varying flow rates, over wide ranges of frequency of variation in flow rates, having a chamber with an outlet, means for varying the chamber volume to cause a volume of gas to be delivered from the outlet, and means for measuring changes in the pressure in and volume of the chamber during the varying, so that the volume of gas delivered therefrom can be derived.
