Abstract: A device for Connection Admission Control for an ATM switch, intended for admitting to the switch a requested ATM connection of the DBR type, such that the “Quality of Service” of all ATM connections of the DBR type in said switch continues to satisfy certain conditions. For the composite traffpg,ic stream of DBR connections at an output port with capacity C, a single buffer with capacity B is available, while as boundary condition it holds that the total average load of the output port does not amount to more than ?×C, where ? is a constant with a value between 0 and 1. The CAC device comprises two sub-devices, which each execute a—rather complex—partial calculation, resulting in a positive or negative admission signal. The new ATM connection is only granted admission to the switch if both sub-devices emit a positive admission signal.

Abstract: The invention relates to a method for the correction or compensation of individual differences between the conversion characteristics of the image sensors (11) and the processing units (12) of an X-ray detector which are connected thereto. It is assumed that a functional relationship in conformity with GW=Fi(Lij(?)) exists between the quantity of radiation (?) entering the detector and the grey value (GW) resulting therefrom for a pixel (j, i), where Lij describes the approximately linear behavior of the sensor arrangement (10) and Fi the non-linear behavior of the processing unit (12). For the inverse value Lij?1 a linear model function is used and for the inverse value Fi?1 a non-linear model function is used with parameters which can be calculated from calibration measurements with different radiation quantities (?k).

Abstract: A prefabricated sealed composite insulating panel for use in commercial and residential buildings. The panel has an insulating core sandwiched between an outer board layer and a skin material that is capable of radiating heat. The insulating core and the skin material are positioned so that they are offset with respect to the outer board layer such that the insulating core and the skin material extend beyond the outer board layer on one lateral side and on one transverse end. The insulating core and the skin material are recessed, with respect to the outer board by equivalent dimensions, on an opposite lateral side and on an opposite transverse end. The insulating core is completely surrounded and encapsulated by a plastic channel that protects the insulating core during transportation and installation. The composite panel, according to the present invention, provides a completely sealed panel that can be easily and efficiently installed on-site.

Abstract: The trench-gate (11) of, for example, a cellular power MOSFET comprises doped poly-Si or other semiconductor material (11a) adjacent to the gate dielectric layer (17) adjacent to the channel-accommodating region (15) of the device. The gate (11) also comprises a sizeable silicide part (11b) that reduces gate resistance. This silicide part (11b) protrudes upwardly from the trench (20) over a distance (z) typically larger than the width (w) of the trench (20), so forming an upstanding part (11b) of a metal silicide material between its top and sidewalls above the level of the body surface (10a). The gate dielectric layer (17) at least adjacent to the channel-accommodating region (15) is protected from the metal silicide by at least the semiconductor part (11a) of the gate and by the protrusion (z) of the silicide part (11b) upwardly above the level of the body surface (10a).

The electrochemical measuring cell has a solid electrolyte tube closed on one end, which is surrounded on the closed end and at least on a portion of its periphery by a steel tube closed on one end. A reference material and a filler material adjoining the reference material are arranged inside the solid electrolyte tube on its closed end. A metal rod is arranged as an electrode along the solid electrolyte tube in such a manner that, on the one hand, it stands in contact with the reference material and, on the other hand, it projects out of the open end of the solid electrolyte tube. The open end of the solid electrolyte tube has a closure which is constructed as a cap, which fits on the exterior of the steel tube or the solid electrolyte tube, and the closure is gas-permeable.

Abstract: A multicast radio data communication system comprising a master (1) and a plurality of slave stations (2, 3, 4), and using a retransmission protocol. Data is transmitted by the master station and received by the slave stations. One slave station is designated the primary slave station, and all other slaves are designated secondary slave stations. Any slave station may transmit a negative acknowledgement but only the primary slave may transmit a positive acknowledgement. Positive and negative acknowledgements are transmitted substantially simultaneously. Negative acknowledgements corrupt reception of the positive acknowledgement by the master station, thereby ensuring that the data is retransmitted. The primary slave station is selected to have the lowest quality radio link, which may be ensured by a power control command from the master.

The one or more channels are adapted to selectively enclose or seal the conductive element.

Abstract: Logos may be present in images transmitted by television stations. These logos are often present in the corners (102, 104) of an image (100) for a long time. They do not move and may comprise saturated colors. This results in burn-in effects in emissive displays because the logos provide the same display load at the same location for a relatively long period of time. The burn-in effect can be prevented by detecting the logos in the corners (102, 104) of the image (100) and reducing their intensity to the average display load.
