Abstract: A plasma picture screen provided with a luminescent layer which comprises a blue Eu2+-activated phosphor and a UV-C light emitting phosphor. The mixing of an UV-C light emitting phosphor with an Eu2+-activated phosphor or coating of an Eu2+-activated phosphor with a UV-C light emitting phosphor or coating of a base layer of an Eu2+-activated phosphor with a covering layer of a UV-C light emitting phosphor clearly reduces the photodegradation of the Eu2+-activated phosphors in the VUV range.

Abstract: An electronic circuit comprising an amplifier includes an output terminal (OUT) for supplying an output signal (Vout) to a load, the amplifier comprising an output transistor (N2, P1) having a first main terminal coupled to a supply voltage terminal (VSS, VDD) of the amplifier, a second main terminal coupled to the output terminal (OUT), and a control terminal. In order to avoid that the output transistor (N2, P1) can enter its linear state which would cause the amplifier to act unacceptably slow for some purposes, the electronic circuit further comprises a controller adapted to prevent the output transistor (N2, P1) to enter its linear state whereby the controller is arranged for reducing a control voltage (Vcntrl) between the control terminal and the first main terminal when an output voltage (Vout) between the second main terminal and the first main terminal is below a defined level.

Abstract: For a minimal electromagnetic radiation during transition between its states, a transmitter for a two-wire, differential databus on which a dominant state can be impressed by means of the transmitter in an active state of the transmitter, and which is in a recessive state when all transmitters connected to the databus are in a passive state, is characterized in that the transmitter is provided with a capacitance (6) and switching means (7, 8, 9, 10) by means of which the capacitance (6) can be alternatively coupled to an electric source (11) or between the two databus lines (1, 2), and in that the switching means (7, 8, 9, 10) charge the capacitance (6) by means of the electric source (11) during periods when the transmitter is in a passive state, and couple the capacitance (6) between the two databus lines (1, 2) during periods when the transmitter is in an active state.

Abstract: A device contains a memory that stores a WOM codeword that encodes successive generations of data values. When the codeword must be updated to represent a new data value, the device determines which updates of the dataword can be realized by feasible single bit updates to the WOM codeword. If no feasible single bit update is possible, feasible two-bit updates are considered. Under control of the new data values a connection circuit routes feasibility signals for various updates, that signal the single-bit feasibility of the updates. Routing brings together pairs of feasibility signals for updates that together produce a WOM codeword that encodes the new data value. A pair is selected in which both feasibility signals indicate feasibility and the codeword is updated according to the updates involved in the pair. Preferably, the routing is realized with a connection circuit that comprises a number of layers of subcircuits, each routing the feasibility signals dependent on a respective bit of the new dataword.

Abstract: The invention relates to an arrangement for position assignment of vehicle wheels (2, 4, 6, 8), in which means (3, 5, 7, 9) for detecting the number of rotations and turning direction of the wheel (2, 4, 6, 8) are assigned to each wheel (2, 4, 6, 8). In accordance with two further embodiments, a steering sensor (11) is provided instead of the means for detecting the turning direction of the wheel. In all embodiments, the vehicle is provided with an evaluation unit (10) which, in the case of a curved trajectory of the vehicle (11), performs a vehicle position assignment of the individual wheels (2, 4, 6, 8) with reference to the number of rotations and turning directions detected for each wheel (2, 4, 6, 8) and possibly with reference to the steering direction.

Abstract: The invention concerns an integrated circuit, including a substrate (SBSTR) with sub-circuits provided with a number of terminals, including a substrate terminal or earthing point (GND), a Vcc power supply terminal, an input point (in) and an output point (out). At least one of the Vcc power supply terminal, the input point or the output point is connected via an overvoltage protection circuit to the substrate terminal or earthing point, and the overvoltage protection circuit includes means with diode action formed in the substrate between the relevant terminal and the substrate terminal or earthing point. The means include two or more diode elements of the Zener type connected in series. The substrate of a first conductivity type is provided with a well (WLL) of a second, opposed conductivity type formed in the substrate.

Abstract: Apparatus (1) for treatment with light for personal care comprising a housing (2) with a light source, which housing (2) is covered with a wall (4) made from a translucent material, on which wall (4) a focusing area (5) is provided, to which focusing area (5) a user's eyes are mainly directed during use. On the wall (4), side areas (6) are provided adjacent said focusing area (5), and at least a portion of the wall (4) has a reference brightness during operation. Means (8) are provided in the apparatus (1) for varying a brightness of the focusing area (5) of the wall (4) during operation between the reference brightness and a minimum brightness which is lower than the reference brightness. In this way, the brightness of the focusing area (5) can be adjusted to a level which is low relative to the brightness of the side areas (6). A user thus experiences looking at the wall (4) during operation as more comfortable because he/she is not looking at a whole area of uniform brightness.

Abstract: Sigma-delta analog-to-digital converter topology with an error signal branch including a subtractor (10), a loop filter (4), and a quantizer (6), and a feedback branch including a digital-to-analog converter (8). The gain error caused by a return-to-zero switch in the feedback branch is cancelled by moving the return-to-zero switch (20) to the signal error branch.
