Abstract: An LED module (1) includes a plurality of LEDs (76 to 89) which are arranged on a printed circuit board (75) and which each have a “bedding element” with a lens (100 to 113) with which the respective LED (76 to 89) protrudes from the printed circuit board plane. The LEDs (76 to 89) are each coupled to a light input element of an optical waveguide body and the respective associated light input element radiates the respective luminous flux from the associated LED (76 to 89) outwards from the LED module (1). To achieve a homogeneous external appearance, the printed circuit board (75) for the LEDs (76 to 89) has at least one passive LED (95, 96, 97) provided thereon.

Abstract: A method is disclosed of using a plurality of simultaneous communication sessions to allow two-way communication where data compositions are simultaneously sent from an apparatus to a large plurality of remote units, while maintaining a high performance of the apparatus, each session involving sending a data composition to a respective of a plurality of remote units through a communication network, the data compositions being stored in a storage unit. The method includes receiving from the storage unit streams of data composition sub-sets, and providing for each of the communication sessions a data queue, and storing data of the streams of data composition sub-sets in the data queues.

Abstract: In a computer system the instruction decoding unit for translating program instructions to microcode instructions operates dynamically. Thus the unit receives state signals indicating the state of the computer, such as a trace enabling signal, influencing the translation process in the instruction decoding unit. These state signals are added to the operation code of the program instruction to be decoded, the operation code of the program instruction thus being extended and used as input to a translating table, the extended operation code of the program instruction being taken as an address of a field in the table. The addresses and thus the contents of the fields addressed for the same operation code of a program instruction can then be different for different values of the state signals. Thus generally, the state signals cause the instruction decoder to change its translating algorithm so that the decoder can decode an operation code differently depending on the state which the signals adopt.
