Abstract: The invention relates to the generating of images by means of a two-dimensional field of image sensors, notably by means of a flat dynamic X-ray detector FDXD. In order to adhere to with the maximum data rate Gmax of an evaluation unit (1) it is necessary to satisfy the relation y.f/b £ Gmax between the width x and the height y of a sub-region of the image sensor read out, the imaging rate f and the binning factor b. In conformity with the method, parameters defining the size, position and/or shape of the sub-region can be preset at will, the other variables of the inequality being adapted, if necessary, in such a manner that the inequality remains satisfied. In the context of the method there is also performed a mosaic calibration during which calibration images of the complete image sensor are composed from calibration images of sub-regions.

Abstract: Hard-open defects between logic gates of, for example, an address decoder and the voltage supply which result in logical and sequential delay behavior render a memory conditionally inoperative. A method and apparatus for testing integrated circuits for these types of faults is proposed, in which two cells of two logically adjacent rows or columns are written with complementary logic data. If a read operation reveals the data in the two cells to be identical, the presence and location of a hard-open defect is demonstrated.

An adaptive filtering device (200) and method where two low-pass FIR filters (202, 204) receive an input signal, a weighted adder (206) receives outputs from the two low-pass FIR filters and changes a weighting of each to produce filtered output data, and a controller (208) that receives a cutoff frequency (203), supplies the cut-off frequency to the two low-pass FIR filters, and supplies a signal to the weighted adder for varying the weighting of each of the low-pass FIR filters to switch therebetween.

Abstract: A record carrier (40) of a removable type has an information plane of a layer of magnetic material on a substrate constituting an array of bit locations (11). A magnetic state of the material represents the value of each bit location. A storage device (35) has an interface surface (32) for cooperating with the information plane. The interface surface has an array (31) of electro-magnetic elements that are sensitive to said magnetic state of the electro-magnetic material. The record carrier and device have alignment elements (38, 41) for positioning the bit locations near the electro-magnetic elements within a near-field working distance between a bit location and the corresponding electro-magnetic element when the record carrier is mounted in the device.

Abstract: The method for recording data comprised in a real time data stream sequentially on multiple recording media reduces the buffer required to temporarily store data from the data stream by starting the change of recording medium when an interruption in the program to be recorded is detected. At least part of the data during the change of recording medium is of less interest to the user and the loss of this data is thus preferred over the loss of data belonging to the program that is to be recorded. By allowing selective loss of data the buffer size is reduced.

The SDM may be part of an analog to digital converter and/or a digital to digital converter.

Abstract: The invention relates to video transcoding between a first and second video standard, such as H.264 and MPEG-2. A video transcoder (201) comprises an interface (203) that receives a video signal in accordance with a first video encoding standard. The video signal is decoded in a decoder (207). An extraction processor (209) extracts motion estimation data from the first video signal, preferably as part of the decoding process. A motion estimation data processor (211) generates second motion estimation data, compatible with a second video encoding standard having a different set of motion estimation options, from the first motion estimation data. The second motion estimation data is generated by projecting motion estimation block positions between reference pictures, aligning prediction blocks with a block position framework and adjusting the prediction block sizes.

Abstract: A total amount, M, of memory is allocated over streaming data buffers (86). The memory is partitioned over a set of streams (88), each stream being given a partitioned amount of buffer memory. Scheduling is repeatedly performed during each filling/emptying cycle. The scheduling includes: spinning up a storage disk (80), filling/emptying each stream buffer by reading/writing from/to the storage disk until the respective stream buffer is full/empty, determining an earliest next spinning up time, putting the storage disk in standby mode, spinning down the storage disk, re-determining, at or just prior to the earliest next spinning up time, a new earliest spinning up time based on current buffer fullness, iteratively re-determining the new earliest spinning up time until the time is within a predetermined closeness to the previous time, or within a predetermined closeness to the current time, and waiting until the next earliest spinning up time, or just prior to that time.

Abstract: Cordless telephones according to the DECT standard are constantly transmitting a so-called dummy barrier at a certain power level, repetition interval and transmit frequency to apply corrections to the synchronisation counters in the portable parts for synchronisation to the fixed part. According to the present invention, once timing of the portable part is synchronised to the fixed part, a wired connection is used for applying these small synchronisation corrections with respect to the synchronisation between the portable part and the fixed part of the DECT telephone system. Advantageously, an emission of electromagnetic energy is thereby reduced significantly.

Abstract: A display device has pixels 41 arranged in rows and columns 42,44 addressed by a grid of first and second addressing conductors 50,52. The addressing conductors 50,52 are not parallel with the pixel rows or pixel columns 42,44. This arrangement decouples the row and columns of pixels from the addressing conductors. This provides freedom in the positioning of the driver circuits, which are positioned at the ends of the first and second conductors, which in turn gives greater design freedom for the shape and position of the display in a product.
