Title: Position determination using one low-earth orbit satellite
Inventor: LEVANON NADAV
IPC: H04W84/06
Filed: 1997-09-26
Abstract: A system and method for determining the position of a user terminal (for example, a mobile wireless telephone) in a low-Earth orbit satellite communications system (100). The system includes a user terminal (106), at least one satellite (104) with a known position and velocity, and a gateway (102) (that is, a terrestrial base station) for communicating with the user terminal (106) through the satellite (104). The method includes the steps of determining a range parameter (802) and a range-rate parameter (806). A range parameter represents a distance between the satellite and the user terminal. A range-rate parameter represents a relative radial velocity between that satellite and the user terminal. The position of the user terminal on the Earth's surface is then determined (810) based on the range parameter, the range-rate parameter, and the known position and velocity of the satellite.

Filed: 1999-06-15
Abstract: A large round baler includes a twine wrap mechanism having twine arms which sweep horizontally between opposite side walls of the baling chamber at a location above the pickup and below the bale starter roll. Mounted to one of the baling chamber side walls is a twine guide finger for guiding the twine to the circumference of the bale such that wraps of twine are spaced from the adjacent end of the bale by a distance sufficient to keep the twine from being fed between the wall and the bale end or from slipping off the end of the bale during handling of the bale once discharged from the chamber. The guide finger, in one embodiment, comprises a spring wire member having a guide end portion that is joined to coils that are mounted about a support rod extending through the side wall of the baling chamber. In an alternate embodiment, the rod has a straight portion extending through the chamber side wall and joined to an inner end shaped to perform twine guidance, the outer end of the straight portion being connected to a coil spring that permits the rod to pivot about its straight portion so that the twine guidance portion of the rod will deflect rearwardly in response to crop being fed to the baling chamber. In both embodiments, the rod is adjustably fixed to the outside of the side wall by a manual adjustment permitting the support rod to be moved in and out among an infinite number of positions within a range of adjustment so as to change the spacing of the twine guide fingers relative to the side wall so as to accommodate bales having surfaces of varying slickness due to different crops and/or crop conditions.

Title: Cleaning articles comprising a cellulosic fibrous structure having discrete low basis weight regions and an inverse emulsion
Inventor: CABELL DAVID WILLIAM
IPC: A61K8/00
Filed: 1998-07-01
Abstract: Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes, which are dry until used, where fluid is released from the article. These articles comprise: a) a carrier comprising a cellulosic fibrous structure having at least a first region of relatively high basis weight that comprises an essentially continuous network and a second region of a plurality of mutually discrete regions of relatively low basis weight which are circumscribed by the high basis weight first region; and b) an emulsion applied to the carrier, where the emulsion provides fluid for cleaning when shear forces are applied to the article. The first and second regions of the cellulosic fibrous structure are disposed in a nonrandom, repeating pattern.  The articles offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for cleaning of hard surfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like). The inclusion of low basis weight regions avoids substantial fluid retention by the cellulosic fibrous substrate, which allows fluid delivery to the surface being cleaned. The articles can be used in many applications requiring the delivery of polar materials, in particular water and water-soluble or dispersible actives. These include toilet tissue, wipes for personal cleansing, such as baby wipes, as well as those for the delivery of water-soluble or dispersible antimicrobials or pharmaceutical actives.
