Abstract: A portable electronic device includes a rendering circuit to visualize large format data files on a narrow display. The large format data files are rendered using either a desktop display mode or a mobile display mode. The desktop display mode renders the data file using data file-specified dimensions and resolutions. The data file is viewable in its entirety by automatic scrolling achieved by moving a cursor near the edge of the display. Data file elements may be edited while in desktop display mode. The mobile display mode renders the elements of the data file as a list with minimal regard for spatial orientation. Navigation in mobile display mode is field-to-field.

Abstract: A method and system for communicating serialized data provides a mechanism for ordering the data in response to a priority. In an embodiment, a server sending the data uses the priority to order the data in a message send queue for sending the data to a requesting device. The server may comprise a gateway and the second device a wireless device communicating with the gateway. The wireless device may send a priority indication in association with a request for the data to facilitate the ordering.

Abstract: A method of securely synchronizing cache contents of a mobile browser with a server includes initiating a session between the browser and server, including transmission of browser state information regarding the cache contents and an authentication key to the server; maintaining a record of data sent from the server to the browser for storage in the cache; maintaining a record of the state information regarding the cache contents transmitted from the browser to the server; and transmitting data requests from the browser to the server, in response to which the server uses the key as a seed generation function and accesses each the record of data and returns only data that does not already form part of the cache contents, and wherein the data includes a result of a hash of data generated by the generation function for authentication by the browser before updating the cache contents with the data.

Abstract: Systems and methods are provided for facilitating access to an electronic device. Password information is stored on the electronic device, and on a portable authenticator. When a user attempts to access the electronic device, the user is prompted to enter a password at the electronic device. The portable authenticator determines the validity of the entered password. The electronic device receives the results of the validity determination from the portable authenticator, and provides access to the electronic device based on the received validity determination.

Abstract: A method, mobile communication device, and system for selective downloading to a mobile communication device are provided. In accordance with one embodiment, there is provided a method on a mobile communication device for downloading data from a content source to the mobile communication device, the mobile communication device being configured for connecting to at least cellular data networks and wireless local area networks (WLANs), the method comprising: receiving a request to download data; determining if the requested data comprises a media file; selecting a communication medium for downloading the requested data in accordance with whether the requested data comprises a media file; and downloading the requested data to the mobile communication device using the selected communication medium.

Abstract: A method and system for communicating serialized data provides a mechanism for ordering the data in response to a priority. In an embodiment, a server sending the data uses the priority to order the data in a message send queue for sending the data to a requesting device. The server may comprise a gateway and the second device a wireless device communicating with the gateway. The wireless device may send a priority indication in association with a request for the data to facilitate the ordering.
