Abstract: A method for transmitting verified notification messages from a service provider to a PID (personal information device) user. The method includes the step of registering a plurality of users and providing each of the users with respective public and private encryption keys. A message is then received from a first user of the plurality of users. The received message is signed with the first user's private encryption key. A signature of the message is verified by using the first user's public encryption key. The authority of the first user to transmit notification messages is then verified. The message is then resigned with the second user's private encryption key and transmitted to at least a second user of the plurality of users, wherein the second user verifies the signature by using the second user's public encryption key.

Abstract: A filtering method and apparatus for an electronic device. The operating system's program registry is copied and then modified to direct all application data to a filter program such as a virus scanning filter program. If the filter program determines that the object is virus free, the copy of the program registry (filter registry) is queried by the filter program to determine the application program associated with the data object. The data object is then forwarded to the appropriate application program.

Abstract: A method of processing data using a portable electronic device includes transcoding, using a processor of the portable electronic device, a first webpage to generate a second web page. The second web page is displayed using a display device of the portable electronic device.

Abstract: A method and apparatus that provides adaptation in the content delivered to a palmtop computer. Connections between a palmtop computer and the Internet can vary from low speed dial-up to very high speed. Also, a palmtop computer's display, memory and processing power can vary considerably. Communication with the Internet is generally through a proxy server that can deduce these considerations from the palmtop computer's serial number and/or other information specified by user. The proxy server can then adapt the content based upon these considerations (e.g. only send two bit gray scale images to non-color palmtop computer, only send first frame of animated gif to low processing power palmtop computer, etc.).

Abstract: A hand-held computer device with integral web page transcoding. A processor, forming a part of the handheld computer has a display coupled to the processor forming a part of the handheld computer, with the display having limited resolution of M×N pixels. A browser program running on the processor facilitates retrieving and viewing of a web page having size greater than M×N on the display. This is accomplished in a browser having an associated browser plug-in that transcodes the web page to a format adapted to the display. The transcoding is carried out by, among other things, generating a menu of frames from the web page to permit a user to select a desired frame for display by selecting frame titles as menu selections and compressing an image to a size suitable for display on the M×N resolution display.

Abstract: A method and apparatus that provides adaptation in the content delivered to a palmtop computer. Connections between a palmtop computer and the Internet can vary from low speed dial-up to very high speed. Also, a palmtop computer's display, memory and processing power can vary considerably. Communication with the Internet is generally through a proxy server that can deduce these considerations from the palmtop computer's serial number and/or other information specified by user. The proxy server can then adapt the content based upon these considerations (e.g. only send two bit gray scale images to non-color palmtop computer, only send first frame of animated gif to low processing power palmtop computer, etc.).

Abstract: A method of routing telephone calls, emails and faxes using a palmtop computer. Using a date book forming a part of a personal information manager application of a palmtop computer, the user enters an appointment into the date book. Such an appointment has a starting and an ending time. The user then selects (either at the time of entry of the appointment or after receipt of an alarm reminder of the appointment) a destination telephone number for routing of telephone calls between the starting time and the ending time. This selection can be in the form of a menu selection of a predetermined profile for routing telephone calls. The palmtop computer then sends a representation of the destination telephone number, the starting time and the ending time to a telephone call server (and/or email server and/or fax server), so that the telephone call server routes telephone calls to the destination telephone number between the starting time and the ending time.
