摘要： A diversity receiver has multiple antenna receiving branches. Each branch has means for estimating at least a receiving channel parameter, and the channel parameter estimating means in one branch are coupled to the channel parameter estimating means in an other branch. This way at least a part of the channel parameter estimate in the one branch is used as an aid for estimating at least a receiving channel parameter in the other branch. This saves processing time and processing power in the diversity receiver, and even results in a higher accuracy when selecting the best antenna and receiving branch.

摘要： A system for authenticating a physical object includes an enrolment device, an authentication device, and a storage for storing authentication data. The enrolment device includes an input for receiving a property set Y of the object measured using a measurement procedure. A processor is used for creating a property set I from the measured property set Y that meet a predetermined robustness criterion. It then creating a property set A from the property set I that includes less information on the actual properties than property set Y, and finally generates a control value V in dependence on properties of the property set A. An output is used for supplying the control value to the storage as part of the authentication data. The enrolment device operates in an analogous way.

摘要： Controlling a lighting system, which comprises a controller (2, 10), lighting units (6), and a sensing device. Each lighting unit comprises a lighting source (12) and a modulated light source (14). A single light source may be used to function as both the lighting source and the modulated light source. Each modulated light source emits uniquely modulated light. A radiation pattern of each modulated light source coincides substantially with a radiation pattern of a lighting source of the same lighting unit. The sensing device is suitable to sense modulated light in a viewing area. Lighting units from which the sensing device senses modulated light are identified from the modulation of that modulated light. The sensing device measures the intensity of the modulated light from the identified lighting unit. The lighting sources are controlled dependent on control data which comprises measuring values of measured light intensities.

摘要： Methods and arrangements are disclosed for embedding and detecting a watermark in a cinema movie, such that the watermark can be detected in a copy made by a handheld video camera. The watermark embedder divides each image frame into two areas. A watermark bit ‘+1’ is embedded in a frame by increasing the luminance of the first part and decreasing the luminance of the second part. A watermark bit ‘−1’ is embedded by decreasing the luminance of the first part and increasing the luminance of the second part. It is achieved with the invention that the embedded watermark survives ‘de-flicker’ operations that are often used to remove flicker caused by the different frame rates of cinema projection equipment and consumer camcorders.

摘要： A method for driving a light source (11, 12, 13) is described, wherein the light source is alternately switched ON and OFF in an ON/OFF pattern, wherein the duty cycle of the ON/OFF pattern is varied to vary the average light intensity of the light source, and wherein the shape of the ON/OFF pattern is varied to transmit data. Thus, a control signal for the light source comprises data information as well as duty cycle information. The duty cycle is varied within a range from almost zero to almost 100%, and data is varied and transmitted without affecting the duty cycle.

摘要： A diversity receiver receives high rate radio signals (for example DVB-T signals) while the receiver is moving at a high speed (for example in or with a car). Two or more antennas are closely spaced and arranged behind each other in the direction of motion for receiving the radio signals. A difference (S2(t)−S1(t)) of a first signal (S1(t)) obtained via the first antenna and a second signal (S2(t) obtained via the second antenna serves as an estimation of the spatial derivative of the receiving channel transfer function. This spatial derivative is interpreted as a temporal derivative and exploited to cancel or at least reduce distortions (for example ICI) due to rapid receiving channel variations.

摘要： The invention relates to controlling a lighting device, particularly to the modulation of light generated by a solid state lighting (SSL) device. The invention provides a method and device for modulating the light emission of a lighting device by keying each pulse (14) of a sequence of pulses (16) contained in the control signal (10) according to a spreading code. Thus, the light emission of a lighting device may be identified by detecting the spreading code used for modulating the light emission. The invention is particularly suitable for lighting means containing several lighting devices such as a LED lighting board with dozens of LEDs since the light emission of each lighting device may be detected by the spreading code used for modulating the light emission.
