Abstract: Apparatus for transferring packet data incorporates a "hand-off" feature that allows the transfer of an existing PPP connection from one packet server to another packet server. Such a hand-off control message or call continue transaction can be initiated by any of the servers involved in the transactions. For instance, assume an initial arrangement where a point-to-point call is set up and in progress between a user and a private network via a first packet server (e.g., a first Serving LAC) and a second packet server (e.g., an Anchor LAC). If, for example, the user moves out of the region served by the first packet server into a region served by a third packet server (e.g., a second Serving LAC), then a hand-off control message transaction, according to the invention, is initiated. Either the second Serving LAC or the Anchor LAC may initiate the call continue transaction. Alternatively, radius servers respectively associated with the packet servers may be employed to perform the call continue transaction. Furthermore, assuming that a communication path is not yet established between the second packet server (e.g., Anchor LAC) and the third packet server (e.g., the second Serving LAC), a communication path (e.g., tunnel) set-up control message transaction may be performed concurrent with the call continue transaction. Still further, at least one packet server (e.g., the Anchor LAC) monitors state variables associated with the packet servers (e.g., the second Serving LAC and the private network) from which it receives packet data.

Title: An improved electrochromic medium capable of producing a pre-selected color
Inventor: SIEGRIST KATHY E
IPC: G02F1/1524
Filed: 1998-03-26
Granted: 2007-12-04
Abstract: An improved electrochromic device, the device incorporating an electrochromic medium that comprises at least three electroactive materials having absorption spectra that add together such that the color of the electrochromic medium can be pre-selected by individually choosing the concentrations of the at least three electroactive materials. The electrochromic medium generally maintains the preselected perceived color throughout its normal range of voltages when used in an electrochromic device. The at least three electroactive materials include at least one electrochemically reducible material (cathodic material), at least one electrochemically oxidizable material (anodic material) and at least one additional electroactive material which may be either an anodic or cathodic material. Thus, there are always three electroactive materials present in the medium, with at least two either being anodic or cathodic materials. The pre-selected color may be chosen from a wide variety of colors and may be, for example, red, orange, yellow, green, blue, purple. For electrochromic mirrors for motor vehicles, a presently preferred color is gray.

Abstract: A delivery system for an oral care substance such as a tooth whitening substance includes a strip of material having a yield point and thickness such that the strip of material substantially conforms to a shape of a tooth and its adjoining soft tissue via permanent deformation under a pressure less than about 250,000 Pascals when the delivery system is placed then against. The delivery system also includes an oral care substance applied to the strip of material such that when the delivery system is placed on a surface of the tooth and its adjoining soft tissue, the substance contacts the surface providing an active onto the surface. The substance also provides adhesive attachment between the strip of material and the surface to hold the delivery system in place for a sufficient time to allow the active to act upon the surface. The substance has an extrusion resistance sufficient to withstand a normal force applied to deform the strip of material so that the substance is not substantially extruded from between the strip of material a nd the surface during manual deformation of the strip of material.
