Graphical display of an animated data stream between devices on a bus

Abstract: A graphical user interface (GUI) displays graphical images representing devices coupled to a bus structure. The bus structure is also graphically represented and illustratively coupled to each of the graphical device images. Preferably, the bus structure is an IEEE 1394 serial bus. The system is preferably a computer system. Alternatively, the system is a television, monitor or other display system coupled to and capable of communicating over the serial bus and including a control processor and a display device. When a device is added to the serial bus, a graphical image representing that device is automatically displayed in the graphical user interface. Similarly, when a device is removed from the serial bus, the graphical image representing that device is grayed out, leaving a shadow of the graphical image until the device is either re-coupled or the system is powered off. Tasks performed by the devices coupled to the serial bus are also controlled and monitored by the user through the graphical user interface of the computer system. In order to control such tasks, a cursor control device is used to choose options displayed in the graphical user interface. One or more task windows are included in the interface which help the user select the task to be performed. Once selected, controls, commands and data related to that task are displayed within a control display window of the graphical user interface. When a task requires data to be sent between devices, the flow of data between the devices over the serial bus network is graphically represented by an animated data stream within the graphical representation of the bus structure. When the data stops flowing between the devices, the animated data stream disappears. When a device is added to the serial bus, an animated stream of data temporarily flows between the graphical image of the new device and the computer system.

Spatial light modulator display pointing device

Abstract: A display system with a pointer that is not restricted by wires or sensors. The display uses a spatial light modulator (14) for projecting an image on the screen (20). During a time period when all of the cells of the modulator (14) are in the same state, a cursor projected onto the screen by the pointer is reimaged from the screen to a detector (26), which translates the cursor image into signals for a central processing unit (38). The central processing unit (38) then directs the system as to what tasks are being dictated by the cursor.

Memory card having static electricity protection

Abstract: A memory card includes a card support formed by two plastic boards; a printed circuit board mounted on the card support; an integrated circuit mounted on the printed circuit board and including a memory for storing information, a central processing unit for accessing the information, and access terminals connected to the memory and central processing unit for accessing the information from the memory; a plurality of connection terminals provided on an exposed surface of the printed circuit board; a common ground discharge pattern provided on the exposed surface of the printed circuit board and separated from the connection terminals by first discharge gaps; a plurality of lead terminals provided on a non-exposed surface of the printed circuit board and connected between respective ones of the connection terminals and respective ones of the access terminals of the integrated circuit; a second discharge pattern formed on the non-exposed surface and separated from the lead terminals by second discharge gaps such that undesirable static electricity supplied to the connection terminals on the exposed surface is discharged to the respective discharge patterns through the first and second discharge gaps.

Picture encoding and/or decoding apparatus and method for providing scalability of a video object whose position changes with time and a recording medium having the same recorded thereon

Abstract: An apparatus and method for obtaining scalability of a video object (VO) whose position and/or size changes with time. The position of an upper layer picture and that of a lower layer picture in an absolute coordinate system are determined so that corresponding pixels in an enlarged picture and in the upper layer picture may be arranged at the same positions in the absolute coordinate system.
