Abstract: A biometric identity confirmation system is based on pulse waveform data for the subject. During an initial enrollment mode, pulse waveform data for a known subject are used to generate subject characterization data for the known subject. The subject characterization data includes an exemplar created by synchronous averaging of pulse waveform data over multiple pulse cycles. A number of trigger candidate are identified for the start point of each pulse cycle. The time delay between trigger candidates is analyzed to discard false trigger candidate and identify true candidates, which are then used as the start points for each pulse cycle in synchronous averaging of the pulse waveform data. During a subsequent identity authentication mode, pulse waveform data for a test subject are analyzed using the subject characterization data to confirm whether the identity of the test subject matches the known subject.

Abstract: An system for monitoring alcohol in the breath of a test client confirms the identity of the test client based on spirometric data. The system includes a sample chamber receiving a breath sample, an alcohol sensor measuring the alcohol content of the breath sample, and a spirometric sensor generating spirometric data from the breath sample over the test clients entire exhalatory phase. A processor analyzes the spirometric data with stored client characterization data for a known client to confirm the identity of the test client. The client characterization data can be a probability density in a phase space in which at least two spirometric variables (e.g., flow and volume time-series data) are correlated.

Abstract: A method and system for biometric identity confirmation is based on the pulse wave of a subject. During an initial enrollment mode, pulse wave data for a known subject are used to generate subject characterization data for the known subject. During a subsequent operational mode, pulse wave data for a test subject are analyzed using the subject characterization data to confirm whether the identity of the test subject matches the known subject. The subject characterization data can be a probability density in a phase space in which at least two quasi-periodic variables based on the pulse wave (e.g., blood pressure and volume time-series data) are correlated.

Abstract: An article called a tibbidy is disclosed to be attached to an outer garment and provide comfort and protection to the person wearing the garment when the person chooses not to wear inner- or undergarments beneath the garment. The article is a lightweight flexible fabric pad which is configured to conform to the inner surface of a garment, such as the inseam and crotch of a pair of pants or the axillary area of a shirt garment. The product has a soft comfortable top layer, optionally an intermediate supporting layer for the top layer, and an adhesive layer for adhesion to the inner surface of the garment. The product exists in various embodiments, some of which are specifically configured for use by women, others for use by men, and others of a “unisex” configuration for use by both men and women.

Abstract: A pipe connector with helically threaded (49, 57) frustoconical pin (10) and box (30) surfaces. The connector is axially (78) snapped together, but is rotated for disengagement. Centralizing surfaces (150, 152) on each thread form abut opposing crests (62, 54) to maintain concentrically, thereby detering disengagement under bending moments.

Abstract: A pipe connector which comprises a tubular box member that is telescopically engageable with a tubular pin member, the members having corresponding frusto-conical inner and outer peripheral surfaces which overlie one another when the members are fully engaged together. To axially lock the members together, the frusto-conical surfaces are provided with pairs of interengageable annular projections and grooves. The projections and grooves have varying axial extents and spacings so that, as the members are telescoped together, in all intermediate positions of the members, there is sufficient contact between crests of the grooves and surfaces between the projections to prevent inadvertent premature engagement of a projection with a groove.

Abstract: The pipe connector comprises a pin member and a box member which have outer and inner generally frusto-conical peripheral surfaces which overlie one another when the members are fully engaged together. To axially lock the members together, the surfaces are provided with interengaging annular projections and grooves. For disengagement of the members, pressurized fluid is supplied between the peripheral surfaces through an inlet in the box member. The ends of the peripheral surfaces are sealed, during disengagement, by providing reversely inclined annular surfaces on the free ends of the pin and box members and correspondingly at the roots of the box and pin members. In use of the connector these inclined surfaces are slightly spaced apart and are brought into sealing contact on application of pressurized fluid between the peripheral surfaces.
