Optionally the non-predeterrnined data values may comprise power control commands for uplink transmit power control.

Abstract: A display device (401) has groups of display elements (118), which are changed from one optical state to another by applying a waveform (330, 331) sequence of potential differences. The waveforms (330, 331) to be applied are stored in a look-up table (445) in a memory of the device (401). The look-up table is ordered so that portions of the waveforms (330, 331) are reused for different groups of display elements (401). The memory requirement for storing the waveforms (330, 331) is reduced.

Abstract: A method for reading data from a track (3) of a data carrier (2) comprises the following steps. During reading, a tracking quality parameter (Q) is determined, relating to a track portion (3Px) of the data carrier from which the data is being read. The tracking quality parameter is stored in a tracking performance memory (30) in relation to the corresponding track portion (3Px). If a jump back to a previously read track portion appears to be necessary, said tracking performance memory (30) is consulted to determine a target track portion (3P(x-n)) having a sufficient value of the tracking quality parameter (Q); then, a jump back (JB) to the target track portion (3P(x-n)) thus determined is performed.

Abstract: A method and apparatus are disclosed for generating and maintaining enhanced background models for use in background-foreground segmentation. Background models are modified to contain an indication of objects that are typically stationary. Thereafter, if an object moves and has been previously identified as an object that is typically stationary, the object will not unnecessarily be identified as part of the foreground during background-foreground segmentation. In an exemplary implementation, moving objects are classified into two sets. A first set includes objects that typically move independently and a second set includes objects that are typically stationary. Generally, once an object is assigned to the second (stationary object) set, the object will remain in the background, even if the object is moved (normally, movement of the object would cause the object to become part of the foreground).

Abstract: The present invention relates to a method and a system for identifying an item (1) to which a radio frequency tag is attached by means of a radio frequency tag detector (101), wherein radio frequency contact is established between the tag and the detector (101) and information associated with the item (1) and being stored by the tag is received by the detector (101) The invention is based on the idea that the data stored by the tag is mapped against a unique item identifier. This unique item identifier is then presented for a user of the detector (101). By employing the present invention, it is possible to identify an item (1) by attaching a small tag to it. This is particularly advantageous in the case where the item (1) to which the tag is attached is very small, such that it is practically difficult to write information on the item (1) itself or on the item casing.

Abstract: A method, transmitter and transmission system for transmitting an MPEG-2 transport stream, wherein a portion of the offered transport stream (20) is selected and transmitted as a partial transport stream (27). When the elementary stream containing the PCR (24) is not part of the selected portion, a new elementary stream (26) containing only the PCR is created and transmitted instead of the original elementary stream (24). This is done by copying the relevant information from the packets in the original elementary stream (24) into new packets.

Abstract: One embodiment of the invention relates to a method for fabricating a semiconductor device having a semiconductor structure with a silicon region which forms at least one connection region in and/or on a surface of a substrate. The method comprises forming a metal cluster layer from a first, non-siliciding metal, followed by the deposition of a metal layer consisting of a second, siliciding metal. A subsequent heat treatment is responsible for forming a metal silicide from the second metal, the atoms of the first metal being displaced in a direction substantially perpendicular to the surface of the substrate. According to one embodiment of the invention, the atoms of the first metal are displaced by the Kirkendall effect to beneath the metal silicide. If an MOST, for example, is being fabricated, this has advantages both at the location of the source and drain region and at the location of the gate electrode.
