Abstract: It is provided a lamp, particularly halogen lamp, for a headlight of a motor vehicle, comprising a light source (12) for emitting mainly white light, a mainly transparent envelope (14) encapsulating the light source (12) and a filter element (22) provided at the envelope (14), wherein the filter element (22) is adapted for deflecting visible light of a predefined wavelength interval such, that mainly blue light can be provided above a bright/dark-cutoff (28). Since the deflected bluish light is above the bright/dark-cutoff (28) an oncoming driver recognizes earlier the light. At the same time the oncoming driver is not blinded by the blue light above the bright/dark-cutoff (28), since not the whole emitted light (40) but only a smaller wavelength interval is directed above the bright/dark-cutoff (28).

Abstract: A storage device host controller such as an SATA (Serial ATA) host controller and a corresponding method are provided for performing host-to-device and device-to-host communications in a PIO (Programmed I/O) data transfer mode and a DMA (Direct Memory Access) data transfer mode. The host controller comprises a buffer unit for buffering data and a data stream selection unit for selecting a data stream for submission to the buffer unit. The data stream selection unit is connected to receive at any one time at least one of a host-to-device data stream in the PIO data transfer mode, a host-to-device data stream in the DMA data transfer mode, a device-to-host data stream in the PIO data transfer mode, and a device-to-host data stream in the DMA data transfer mode, and select from the received data streams the data stream to be submitted to the buffer unit.
