Abstract: An active matrix display device has pixels each with a light-sensitive device (84) for optical feedback functions. Each pixel has a light blocking structure (100) formed from the thin film layers of the display substrate in the proximity of the light-sensitive device (84) and substantially at the level of an input surface of the light sensitive device. This structure prevents the passage of light (g) to the light sensitive device from a substantially lateral direction.

Abstract: A frequency-tunable arrangement comprises a resonance circuit (RS) having a capacitive part (C1, C2, Cv1, Cv2) that is tunable throughout a capacitance range. A plurality of amplifiers (AB, AS1, AS2, AS3) is coupled to the resonance circuit so as to form an oscillation loop. At least one of the amplifiers is a switchable amplifier (AS1) that is switchable between an active state and an idle state. The switchable amplifier causes a capacitance variation in parallel to the capacitive part of the resonance circuit when switched between the active and the idle state. The switchable amplifier is arranged so that the capacitance variation substantially corresponds to the capacitance range throughout which the capacitive part can be tuned.

Abstract: The present invention provides a method for generating a timing offset signal applied to a sampling device for recovering a symbol stream from a broadcast signal by characterizing the dispersion of received signal. Preferably, the method includes steps for generating a derivative signal approximating the derivative of the symbol stream, producing a constant representative of an expected symbol stream, and multiplying the derivative signal, the constant, and a signal one of corresponding to and approximating the symbol stream to thereby generate the timing offset signal. A dispersion characterizing receiver and a digital signal processor employed therein are also described.

Abstract: A DSV control bit determining/inserting unit inserts DSV control bits for execution of DSV control into an input data string and outputs the data string including the DSV control bits to a modulation unit. This modulation unit converts the data string with a basic data length of 2 bits into variable length code with a basic code length of 3 bits in accordance with a conversion table and outputs the code resulting from the conversion to a NRZI encoding unit. The conversion table used by the modulation unit includes substitution codes for limiting the number of consecutive appearances of a minimum run to a predetermined value and substitution codes for keeping a run length limit. In addition, the conversion table enforces a conversion rule, according to which the remaineder of division of the “1” count of an element in a data string by 2 having a value of 0 or 1 shall always be equal to the remainder of division of the “1” count of an element in the code resulting from conversion of the data string by 2.

Abstract: This device (1) enables the user to personalize the call signal (ringing) which it is called on to deliver. This personalization consists of transforming a melody (FIG. 1) which the user hums into his microphone in order to transform it into a polyphonic melody (FIG. 8). Application: Ringing for mobile telephones.

Abstract: A system for monitoring a physiological condition of an individual. The system (1) comprises sensing means (3) arranged to pick up a first signal (M) in a first mode of the system, said first signal being representative of the physiological condition and to forward the first signal to a signal processing unit (33). The system comprises an actuatable control unit (2) positioned remote from the signal processing unit, the control unit (2) being suitable to generate a second signal (T) arranged to be superimposed on the first signal (M). The signal processing unit (33, 37) is arranged to decode the second signal and to make the system enter into a second mode upon receipt of the second signal (T).

Abstract: A system (100) comprising read means (112) for reading content data and control logic data from a storage medium (101), the control logic data being uniquely linked to the storage medium (101), processing means (113-117), for processing the content data and feeding the processed content data to an output, and control means (120) for executing the control logic data and for controlling the processing means (113-117) in accordance with the control logic data being executed. The link is preferably realized by variations in a physical parameter of the storage medium (101) that exhibit a modulation pattern representing a necessary parameter for obtaining access to the control logic data. Alternatively, the link is realized by an integrated circuit (201) on the storage medium (101) which contains the necessary parameter. The necessary parameter may comprise a decryption key or authentication data.

Abstract: An apparatus for carrying out steps in the manufacture of a device under a prescribed pressure, the apparatus including a reactor chamber for accommodating the body, a gas supply pipe for introducing a process gas flow, an exhaust pump, an exhaust pipe, a pressure control valve for adjusting a valve opening, a pressure sensor and a control device. The pressure control valve comprising a first flow-through element and a second flow through element arranged behind each other in the exhaust pipe in the direction of the gas flow. Movement of either the first flow-through element or the second flow through element substantially transverse to the direction of gas flow establishes a desired overlap between the first flow-through element and second-flow through element and creates a common opening. The design of the pressure control valve renders the pressure control valve controllable in an almost fully-closed position, widening the range of prescribed pressures controllable with the valve.

Abstract: A computer system with a multi-master system bus includes a memory controller that changes the burst mode of the including memory system automatically as a function of the selected master. The controller includes a programmable look-up table into which is stored a value B corresponding to a fixed memory burst mode; for each master, a multiplier is stored indicating the multiple of the burst mode that would be optimal for that master. The grant signal used to select the current master is also used to select the multiplier M associated with that master. In response to a read request by the current master, a requested address is forwarded to the memory. Then the controller generates and transmits M−1 addresses spaced B addresses apart every Bth bus cycle. This implements a memory system burst of M*B addresses with no latencies between successive B-address memory bursts. The memory system burst can be aborted if an address in the burst is not confirmed by a subsequent address request by the master.

Abstract: In a SEM it is desirable, in given circumstances, to acquire an image of the sample (14) by means of Auger electrons extracted from the sample and traveling back through the bore of the objective lens (8) in the direction opposing the direction of the primary beam. It is known to separate extracted electrons from the primary beam by positioning Wien filters (32, 34) in front of the objective lens (8), the filters being energized in such a way that they do not cause deflection of the primary beam but do deflect the secondary electrons. This technique cannot be used for Auger electrons, considering their high energy and hence much stronger fields in the Wien filters, thus causing substantial imaging aberrations in the primary beam. According to the invention a quadrupole field is applied in the same position as the fields of each Wien filter (32, 34, 36), thus ensuring that the resolution of the image of the sample (14) is not degraded by the fields of the Wien filters.

The invention also relates to a correspondingly constructed X-ray device.
