Abstract: A system and method are provided for sharing data among a plurality of users. Included are a plurality of personal digital assistants, or PDA's, each suitable for storing a plurality of personal data sets thereon. Associated therewith is a server including a plurality of server data sets stored thereon. A communication link between the PDA's and the server is adapted for synchronizing the server data sets with the personal data sets in order to obtain the personal data set of one PDA on another PDA, thereby synchronizing the personal data sets between different PDA's. The personal data sets of each of the PDA's have personal identification codes assigned thereto and the server data sets of the server have server identification codes assigned thereto.

Abstract: A system and method are provided for sharing data among a plurality of users via an intermittently accessed network. Included are a plurality of personal digital assistants, or PDA's, each suitable for storing a plurality of personal data sets thereon. Also provided is a server for synchronizing a plurality of server data sets stored thereon with the personal data sets stored on the PDA's. A plurality of client computers are included for providing a communication link between the PDA's and the server. Each communication link is suitable for obtaining the personal data set of one PDA on another PDA, thereby synchronizing the personal data sets between different PDA's. In the absence of communication between the client computer and the server, the communication link is further suitable for interfacing local memory of the corresponding client computer to synchronize a plurality of local data sets stored thereon with the personal data sets during synchronization.

Abstract: A portable, hand-held personal digital assistant is provided for simultaneously depicting multiple calendars on a single display. The personal digital assistant includes a portable, hand-held housing including a top face, a bottom face, and a side wall therebetween for defining an interior space. An input device is situated on the top face of the housing for allowing input of data. Associated therewith is a display situated on the top face of the housing for depicting data. Situated in the interior space of the housing is memory for storing a plurality of calendars each including a plurality of scheduled matters. Finally, controller is situated in the interior space of the housing and connected between the input device, the display, and the memory. The controller serves for simultaneously depicting a plurality of the calendars on the display. By conveniently displaying the multiple calendars, the present invention allows a user to more effectively manipulate the same.

Abstract: A system and method are provided for sharing calendar data sets among a plurality of users. Included are a plurality of personal digital assistants, or PDA's, each suitable for storing personal calendar data sets thereon. Further provided is a server for synchronizing server calendar data sets stored thereon with the personal calendar data sets stored on the PDA's upon establishing communication therebetween. At least one communication link is adapted for establishing communication between the PDA's and the server. By establishing such communication between the PDA's and the server, the personal calendar data sets of different PDA's may be synchronized.
