Publication number: 20030084302Abstract: A method for browsing a data communications network includes requesting user data from a user-controlled secure device if a network site that requires the user data is accessed. The request is performed prior to requesting the user data from another device. The method also includes sending the user data to a network server associated with the network site if the user data is received from the user-controlled secure device. According to another aspect, a method for servicing data communications network information units includes receiving user data associated with a network site, using the user data if the user data includes static user data and reconstructing the user data before using the user data if the user data includes dynamic user data.Type: ApplicationFiled: October 29, 2001Publication date: May 1, 2003Applicant: Sun Microsystems, Inc., a Delaware CorporationInventors: Eduard K. de Jong, Moshe Levy, Albert Y.

Patent number: 4154020Abstract: An improved rose plant propagation process which can be carried out on an expeditious basis is provided. Stem segments from a scion rose plant and an understock rose plant are obtained during an active stage of growth. An end of a scion segment is placed into a cut formed in an understock segment, and an end portion of the understock segment is placed in a rooting medium. Roots simultaneously are formed on the understock segment while a graft union between the scion and understock rose plant stem segments is formed. The portion of the understock stem above the graft union next is removed. The process of the present invention offers a reliable rose plant propagation technique not heretofore available to the rose industry whereby quality new rose plants readily can be formed on an economical basis in a significantly shorter period of time than commonly required for prior rose plant propagation techniques.Type: GrantFiled: April 17, 1978Date of Patent: May 15, 1979Inventors: Uriel Paz, Moshe Levy, Zwy Levy
