Abstract: The present invention provides a method for adapting a transmission mode of a content provided on a server to a client. The server instructs the client to automatically change from a poll mechanism to a push mechanism or vice versa depending on a parameter related to content transmission. The parameter monitored by the server can be the content publication rate, negative polling attempts by the client, or the current network load.

Abstract: A web application (630) for a web browser that is downloaded as a web page includes a set of links arranged as a matrix array (633) with the links being invisible on a display of a device running the web browser, and scripting logic (635) for maintaining focus of a navigator of the device on a center one of the links in the matrix array and for updating the web browser to reflect a function associated with an activation of the navigator.

Abstract: Vector-based images and documents, such as those written in SVG and Adobe Flash, can be converted into equivalent bitmap or other non-vector-based image by parsing the vector-based image to detect objects in the vector-based code. For each detected object, a separate bitmap of the object is created and information about where that image lies on the z-axis is retained. A separate bitmap image is created for each object, and the separate bitmap images are layered on top of one another, which is to say ordered along the z-axis in accordance with their z-axis coordinates. Animation of an image can be implemented by selectively rendering different ones of the bitmap images as transparent.
