Abstract: A voltage drop compensating circuit is disclosed which compensates for unwanted voltage drops along a DC current conductor connected to an integrated circuit. The compensating circuit includes a differential amplifier connected between a voltage supply and the conductor form the integrated circuit which is marred by the voltage drop. One input terminal of the amplifier is connected to the supply lead and an output terminal of the amplifier is connected to the conductor. A feedback network is connected between another input terminal of the amplifier and the integrated circuit. A potential difference between the two input terminals on the amplifier will lead to the amplifier adjusting a potential on the output terminal until the unwanted voltage drop along the conductor is compensated for.

Abstract: A method and system for communicating data between an integrated circuit and each of a first device and a second device. Communications between the integrated circuit and the first device use a first interface protocol, while communications between the integrated circuit and the second device use a second interface protocol. Both interface protocols, however, share the same data bus and clock bus. To communicate using the second interface protocol, the first device, which uses the first interface protocol, is first deactivated by sending address data via the shared data bus that does not identify the first device, thereby causing the first device to enter an inactive state until a stop condition is detected on the shared data bus. Then, communications using the second interface protocol can be carried out, provided that a start or stop condition for the first interface protocol is not inadvertently generated on the shared data bus.

Abstract: The invention refers to monitoring usage of digital content provided from a content provider over a network to a client system. In the client system, a logging agent generates and stores information concerning usage of the digital content individually for each usage to be monitored. The generated information is entered in a usage log, either stored in the client system or at a trusted party. The logged usage information is also authenticated allowing identification of the client using the associated digital content. The entries of the log may include a representation of the content, information about usage quality and/or usage time. The logging agent is preferably implemented in a portable tamper-resistant module, e.g. a network subscriber identity module. The module may be pre-manufactured with the logging agent, or the agent can be downloaded thereto.

Abstract: Circuito eléctrico y método para eliminar la influencia de una caída de voltaje. La invención resuelve un problema de compensar una caída de voltaje indeseada a lo largo de un conductor eléctrico de corriente CC (10) conectado a un circuito integrado (20) . El aparato de la invención incluye un amplificador diferencial (106) conectado entre un suministro de voltaje (105) y el conductor eléctrico (10) desde el circuito integrado (20) que es dañado por la caída de voltaje. Un terminal de entrada (103) del amplificador (106) está conectado al cable de suministro (105) y un terminal de salida (109) del amplificador (106) está conectado al conductor eléctrico (10) . La red de alimentación (51) está conectada entre otro terminal de entrada (104) del amplificador (106) y el circuito integrado (20) . Una diferencia de potencial entre los dos terminales de entrada (103, 104) en el amplificador (106) hará que el amplificador (106) ajuste un potencial en el terminal de salida (109) hasta que se compense la caída de voltaje indeseada a lo largo del conductor eléctrico (10) .

Abstract: The present invention relates to a method for applying conductive lines, preferably power lines, on the plastic casing of a mobile phone. The phone casing (100) is covered by a first plastic material (200) rejecting deposition of a metal, and then covered by a second plastic material (300) in strings on the first plastic material corresponding to the desired conductive lines, wherein the second plastic material (300) accept the deposition of metal, after which the metal is deposited on the second plastic material (300).

Abstract: The present invention relates to a display device that can provide multiple display modes allowing the display of images of differing color depths without requiring additional memory. In a first display mode, the display system displays an image at a first size and a first colour depth. In a second display mode, the display system displays an image at a decreased size and an increased colour depth.
