Abstract: The present invention relates to driving mean for an electrowetting display device having a picture element. The driving means is arranged to apply, prior to a data write signal (DT), a voltage signal (DS) to said picture element. Further, the voltage signal (DS) is arranged to have a duration and voltage level that allow said picture element to maintain their optical states.

Abstract: A device for recording records a series of blocks (42) having continuous logical addresses, e.g. digitally encoded video, on a record carrier at a corresponding physical address range. Some physical addresses are assigned to defect management areas (43). The logical addresses are translated into the physical addresses in dependence of the defect management information. The device has contiguous recording means for detecting if the allocated physical address range is interrupted by a subset of physical addresses assigned to a defect management area. If so, the subset of physical addresses is reallocated to the user data area. The series of blocks (42) is contiguously recorded extending over the subset of physical addresses. The defect management area may be eliminated, shifted to a new location (51) after the end of the recorded file or shifted to the end of the medium.

Abstract: A frame format decoder (22) and training sequence generator (24) for determining the frame format of received data which is compliant with the IEEE 802.11b standard for wireless local area networks, and for providing a training sequence for an adaptive equalizer (16). The received signal is first despreaded, demodulated and descrambled, so that the SYNC field is reconstructed, and then a counter 32 counts the number of consecutive bits having the same polarity or logic value until N such bits are counted (where N is an integer greater than 1). The polarity or logic value of the N counted bits enables the decoder (22) to determine whether the frame format is long or short. A training sequence, being a copy of the transmitted SYNC field eventually followed by an SFD field, is also generated for use by an adaptive equalizer (16).

Abstract: Driving of a two-sided viewable display (a display that provides information on both sides) is performed by means of mirroring switching circuits Techniques for simultaneous (total or partial) view are also proposed.

Abstract: A signal processing circuit (1) comprises a first signal generator (10) which generates a DC-level (DL). A second signal generator (11) generates an AC-signal (AS) which is not related to the DC-level (DL). A combining circuit (12) combines the DC-level (DL) and the AC-signal (AS) into a combined signal (CS). And a common processing circuit (13) processes the combined signal (CS).

Abstract: To provide a method for the self-testing of a reference voltage in electronic components, by means of which method there is defined a circuit arrangement for a self-test of the reference voltage that can be implemented in the form of an on-chip test, i.e. for which no external reference-voltage source is required, provision is made for the reference voltage (Uref) to be the variable of a function f(Uref) that has an extreme at the point where the selected nominal value (Uref.

Abstract: For use in a video processing system that is capable of processing a video stream using a chain of video processing algorithms, there is disclosed a system and method for optimally configuring control parameter settings of each video processing algorithm within the chain of video processing algorithms in order to provide a high quality video image. The video processing system of the present invention comprises a chain of video processing algorithms, an optimization unit, and an objective quality metric unit. An output video stream from the chain of video processing units is fed back to the objective quality metric unit. The objective quality metric unit calculates a fitness value and provides the fitness value to the optimization unit. The optimization unit uses the fitness value to configure the control parameter settings for the video processing algorithms. In one advantageous embodiment of the present invention, the optimization unit uses a genetic algorithm in the optimization process.

Abstract: The invention relates to a radiation detector for converting electromagnetic radiation (15) into electric charge carriers. The invention also relates to an X-ray examination apparatus provided with such a radiation detector, and to a method of manufacturing a radiation detector. In order to achieve a small building height of the radiation detector while nevertheless satisfying the same requirements as regards the resetting of the converter arrangement (16, 18) by means of an illumination device (6), it is proposed to provide a supporting layer (8) underneath a glass plate (2a) with a photosensor arrangement (2b), which supporting layer on the one hand provides uniform distribution of the light incident from below and on the other hand imparts the necessary stability to the radiation detector.

The housing (20) forms a substantially dust-proof space. Part of the lamp (1) extends outside the housing (20) through a wall (18,19) of said housing, which wall (18,19) abuts against the lamp (1) in a substantially dust-tight manner at the location where the lamp (1) passes through the wall (18,19).

The medium (20) comprises a substrate (1) with deposited on a side thereof a first stack (2) L0 comprising a first phase-change type recording layer (6). The first recording stack (2) is present at a position most remote for the entrance face (16). At least one further recording stack (3)Ln, which comprises a further phase-change type recording layer (12), is present closer to the entrance face (16) than the first recording stack (2). A transparent spacer layer (9) is present between the recording stacks (2, 3).

The command code is downloaded from an internet server into a personal computer or set-top box, which is coupled to an infrared transmitter. The universal remote control is placed in front of the infrared transmitter and the command code is transferred to the universal remote control, for example in response to the user indicating a key, shown in a displayed picture of a control panel of the electronic appliance and associated with said command code.

Abstract: An interaction simulator uses computer vision, and inputs of other modalities, to analyze the user's mental state and/or personality. The mental state and/or personality are classified and this information used to guide conversation and other interaction. In a chatterbot embodiment, the substance of the conversation may be altered in response to the mental state and/or personality class, for example, by changing the topic of conversation to a favorite subject when the user is sad or by telling a joke when the user is in a good mood.

Abstract: A flexible two-way telecommunications system is disclosed having geographically distributed primary stations whose coverage areas define contiguous cells. Secondary stations are capable of roaming between and within the coverage areas of the primary stations. Downlink communications from the primary stations use TDMA transmission and uplink transmissions from the secondary stations use CDMA/TDMA transmissions. Data packets transmitted on the downlink are modulated to suit the quality of the link between the primary station and the addressed secondary station. A header applied to the downlink transmission includes information about the location of the respective data packets relative to a reference point and the modulation scheme applied to each data packet.
