Abstract: A user interface for screen phones monitors telephone line state information and displays user interface controls and telephone line status information dependent on the telephone line state. The user interface includes a display element referred to as a call slip that expands and collapses in response to changes in telephone line state and user input. The call slip updates the information that it displays based on telephone line state changes and information communicated from one or more telephony monitoring applications. The call slip displays user interface controls representing tasks that are dependent on information derived from a telephone call, such as caller ID information. The software used to control the display of call slips and to monitor telephone line state is part of a software platform that may be customized for a particular device or application.

Abstract: An apparatus for storing multi-bit pixel data comprises a random access memory, for storing a plurality of pixels at each addressable memory location, the memory having one write enable and one data input for each bit of each pixel at a currently addressed memory location. Means are provided to couple each line of a data bus to the write enable inputs associated with corresponding bits of each addressed pixel and to place a common bit, in a selected state, on every data input assosciated with a corresponding bit of each currently addressed pixel, thereby permitting a processor to rewrite the addressed pixels with a selected pixel value, provided the write enables of each pixel are activated by an appropriate bit on the associated data bus line, and thereby permitting a processor to write pixel data to the memory using only one bit per pixel on the data bus.

Abstract: In a graphics display system, a cursor is used to pan a viewport relative to a block of stored information only part of which is selectable to be viewed through the viewport. As long as a cursor remains within the viewport, it can be utilized in a conventional manner under the control of a mouse or the like to provide interaction with display information. When the cursor is moved outside the viewport of the display, the viewport is panned to include the cursor.
