Title: Information service broadcast control in a wireless communication network
Inventor: BALASUBRAMANIAN SRINIVASAN
IPC: H04B7/26
Filed: 2003-07-30
Abstract: A wireless communication network limits the service areas within the network by transmitting time registration flag information in each of a plurality of network service areas. The flag information indicates whether registration for a given broadcast service currently is required for mobile stations in the service area that desire access to the broadcast service. Thus, the transmitted flag information may be used to prompt for such registrations and detecting whether any registrations are timely received in response to such prompting permits the network to timely deactivate one or more broadcast services. Each service area controls one or more service zones, each of which may include multiple member service areas and, preferably, the network activates a requested broadcast service per service zone and deactivates that service per service area. The timing of such deactivations may be made compatible with mobile stations that do not recognize transmitted registration flag information.

Title: Pleated tissue and adhesive arrangement for the absorbent core of an extensible absorbent article
Inventor: JUSTMANN DAVID A
IPC: A61F13/15
Filed: 2003-05-06
Abstract: An extensible absorbent article or garment has an extensible top sheet layer for facing the body of the wearer; an extensible back sheet layer for an exterior layer facing away from the body of the wearer; and an absorbent core layer located between the top sheet and the back sheet. The absorbent core has a tissue layer acting as a boundary layer or web between the top sheet and the fluff pad of the absorbent core. The tissue web of the absorbent core has an adhesive discontinuously applied thereto for attachment to the top sheet or other extensible layers to avoid tearing the tissue when the extensible layers expand. The tissue web may further be pleated to allow for its extensibility. The discontinuity of the adhesive then allows the pleats to perform their expansion function unbound and thus the tissue can extend without tearing, thereby maintaining the integrity of the tissue barrier.
