  • Publication number: 20130208484
    Abstract: A lighting assembly comprising a base body configured as a heat sink (18) having a front surface (18a), a board (14) carrying a light radiation source (12) applied on the front surface of the heat sink, and a fixing element (20) mounted on the front surface of the heat sink with the board arranged therebetween. The fixing element includes a window (22) which leaves at least partly uncovered the light radiation source, such window having side walls (220) which surround the light radiation source and spread outward to form a reflector for the light radiation.

  • Patent number: 6408366
    Abstract: A monitoring processing device (SW) comprises a plurality of process means (A, B, C) which monitor a status of a hardware device (HW) by reading status information from an interface device (ID) via respective accesses (SAA, SAB, SAC). According to the invention the interface device (ID) comprises a first memory (MEM1), a mapping means (MAP) and a plurality of second memories (MEM21, MEM22, MEM23). The mapping means (MAP) uses a predefined mapping pattern (MPN) to map at least a part of a status information stored in the first memory (MEM1) as a bit pattern to at least one second memory (MEM21, MEM22, MEM23). Thus, each process means (A, B, C) is provided flexibly and individually with its own status information which cannot be disturbed by other process means. Thus, an accurate provision of status information in a flexible manner is achieved.
