Title: Determining propagating and clear frequency in wireless data communications network
Inventor: FIZGERALD BRENDAN T
IPC: H04W72/06
Filed: 1996-06-03
Abstract: A two-way communications system that provides ubiquitous wireless data communication services by using a network of only few, widely distributed radio base station (RBS) sites (60) and the existing paging network infrastructure. The paging network infrastructure is used as an outbound link to request data from the remote field units. The outbound page message indicates a time and HF frequency at which the RBSs can expect to receive inbound data from the field units. A network hub or mission operation center (MOC) (30) determines a radio frequency which is expected to be propagating and clear at the time that a particular field unit is to use the frequency as an inbound link. The MOC issues the request for data to the field unit using an existing inexpensive wireless system such as the paging network infrastructure, and an HF transmitter to report remote data such as geoposition or other sensor data.

Filed: 1996-12-20
Abstract: An improved absorbent consumer paper product such as toilet tissue and a method and system for making such a product involves an improved drying fabric that forms an aesthetically pleasing and functionally superior pattern on the paper web before creping. The drying fabric is characterized by a plurality of shute threads extending substantially parallel to each other in a cross-direction of the drying fabric; and a plurality of warp threads extending substantially parallel to each other in a machine direction of the drying fabric. The shute and warp threads are woven together so as to define a number of relatively long warp knuckles at locations where one of said warp threads crosses over at least four of the shute threads. The long warp knuckles are positioned in a shed pattern so as to form (a) a first axis of bulky ridges that are defined by long warp knuckles which are positioned next to each other on adjacent warp threads, the first axis being disposed at a first angle with respect to the cross-direction of the drying fabric that is substantially within the range of greater than 68 degrees but less than 90 degrees; and (b) a second axis formed by each of the long warp knuckles with other, overlapping long warp knuckles on nearby, but not immediately adjacent, warp threads, the second axis forming a second angle with respect to the cross-direction of the drying fabric and being less than about 28 degrees. This pattern improves crepeability of the web and forms a bulky, absorbent, soft tissue product characterized by parallel, continuous low density ridges of substantially uncompressed fibers.
