Patent number: 6353839Abstract: To accept, store, and use dynamic information within a markup language, a markup language variable system is introduced. The markup language variable system allows variable scopes to be created within markup language user agents. Variables can then be assigned using static variable assignment via markup language tags or dynamic variable assignment via user requests. Variables can be used within markup language displays or within addresses such as Uniform Resource Locators (URLs). Automatic escaping ensures that variables are correctly modified for use within certain contexts such as URLs.Type: GrantFiled: April 30, 1998Date of Patent: March 5, 2002Assignee: Openwave Systems Inc.Inventors: Peter F. King, Russell S. Greer, Bruce V. Schwartz, Bruce K. Martin, Jr., Mark G. Lentczner, Lawrence M. Stein

Patent number: 6301471Abstract: A method and system are disclosed for providing subscriber loyalty and retention techniques These techniques are suitable for mobile devices with small screens and limited keypad communication. This system and method allows mobile subscribers who have been identified as being likely candidates for churning, to efficiently, visually and interactively, review an offer for a mobile service plan better meeting the subscriber's needs. The subscriber can review and execute the offer using the display and interface of a mobile device.Type: GrantFiled: November 2, 1998Date of Patent: October 9, 2001Assignee: Openwave System Inc.Inventors: Cynthia N. Dahm, Andrew L. Laursen

Patent number: 6288718Abstract: According to one aspect of the disclosed system, a user supplies character-based queries to retrieve and display a record from a structured database. For every character the user enters, a progressively reduced list of indexes that start with the entered characters is displayed. When a desired index identifying the record is among those indexes being displayed, the user may cease the character entry and scroll a zoom window upon the desired index to explore the record. According to another aspect of the disclosed system, the zoom window maintains a display of an index and at least one field of a record. Consequently, the user can access and display pertinent information of a certain record from a database quickly and efficiently with less keystrokes.Type: GrantFiled: November 13, 1998Date of Patent: September 11, 2001Assignee: Openwave Systems Inc.Inventors: Andrew L. Laursen, Craig Payne

Patent number: 6263437Abstract: A crypto-ignition process is needed to establish an encrypted communication protocol between two devices connected by an insecure communication link. The present invention introduces a method of creating an identical secret key to two communicating parties is conducted between a thin device and a server computer over an insecure data network. The thin device generally has limited computing power and working memory and the server computer may communicate with a plurality of such thin devices. To ensure the security of the secret key on both sides and reduce traffic in the network, only a pair of public values is exchanged between the thin device and the server computer over the data network. Each side generates its own secret key from a self-generated private value along with the received counterpart's public value according to a commonly used key agreement protocol, such as the Diffie-Hellman key agreement protocol.Type: GrantFiled: February 19, 1998Date of Patent: July 17, 2001Assignee: Openware Systems IncInventors: Hanqing Liao, Peter F. King

Patent number: 6150962Abstract: A predictive data entry method permits a user of a device to efficiently enter data using a keypad where each of a plurality of keys represents a plurality of different characters. When the user presses one of the keys representing multiple characters, the predictive data entry method determines the character within the multiple characters most likely desired by the user. Thus, in most instances, a single key stroke is sufficient to select the desired character.Type: GrantFiled: June 14, 1999Date of Patent: November 21, 2000Assignee: Phone.com, Inc.Inventor: Alain S. Rossmann

Patent number: 6148405Abstract: The present invention is a method and system for establishing an authenticated and secure communication session for transactions between a server and a client in a wireless data network that generally comprises an airnet, a landline network and a link server therebetween. The client having limited computing resources is remotely located with respect to the server and communicates to the server through the wireless data network. To authenticate each other, the client and the server conduct two rounds of authentication, the client authentication and the server authentication, independently and respectively, each of the authentication processes is based on a shared secret encrypt key and challenge/response mechanism. To reach for a mutually accepted cipher in the subsequent transactions, the server looks up for a commonly used cipher and forwards the cipher along with a session key to the client.Type: GrantFiled: November 10, 1997Date of Patent: November 14, 2000Assignee: Phone.com, Inc.Inventors: Hanqing Liao, Stephen S. Boyle, Peter F. King, Bruce V. Schwartz

Patent number: H1426Abstract: An apparatus and method for determining the optical power transmitted through an optical fiber. The invention is based on measuring the intensity of the fluorescence produced by a doped segment of an optical fiber. The dopant is selected so that it emits light at a different wavelength than that responsible for producing the fluorescence. The doped segment is of sufficient length and dopant concentration to provide a detectable signal, but short enough to prevent the doped segment from serving as a gain medium, resulting in amplified spontaneous emission and excess fluorescence traveling along the optical fiber. The dopant material is excited by the optical signal carried by the fiber, causing a fluorescence. In the preferred embodiment the intensity of the fluorescence is proportional to the intensity of the propagating light. The signal power is then determined from the intensity of the fluorescence.Type: GrantFiled: October 28, 1992Date of Patent: April 4, 1995Assignee: The United States of America as represented by the United States Department of EnergyInventor: John S.
