Abstract:
An extension indicator is provided for determining a predetermined extension applied to an extensibly deformable article such as medical bandage used in compression therapy. The indicator includes first (420) and second (430) co-operating members, each adapted to be secured to an extensibly deformable article (440). One of the members is more extensible than the other and each member (420, 430) bears visual indicia (450, 460, 470) which upon extension of the more extensible member, are adapted to align with each other to indicate a predetermined extension of the more extensible member.
Abstract:
The present invention relates to a disposable absorbent article comprising a chassis defining a front waist region, a rear waist region, and a crotch region disposed between the front waist region and rear waist region. The article includes front and back ear panels that are joined at opposing side seams. The side seam can include an initiation region, which can be bonded or unbonded, and a propagation region. The initiation region and the propagation region have a resistance to user-applied opening forces. The resistance at the initiation region is less than that of the propagation region. The seam can further include additional regions. The article can include a tab member that can be engaged by the user to facilitate opening of the seam.
Abstract:
A security thread for use in a paper-based value document, such as currency or banknote paper, includes a plastic substrate coated with one or more regions of "soft" magnetic material. A device for verifying both the authenticity and the denomination of the document includes a coil that is driven by an alternating current to thereby provide a uniform magnetic field within a predetermined spatial region. As the document passes in proximity to the drive coil, the applied magnetic field saturates the regions of magnetic material on the security thread. The magnetic regions provide a response magnetic field that, because of the saturation of the magnetic regions, is a non-linear response containing a multiple of frequency components, including a component at the fundamental or drive frequency and various harmonic frequency components. A receive coil senses the response magnetic field. A signal processor connected to the receive coil utilizes the response signals at the fundamental frequency and the low-order harmonic frequencies to determine both the type of magnetic material on the security thread and the denomination of the document from the spatial distribution of the magnetic regions on the security thread.
