Abstract: Sweat ducts present on finger prints can be used in biometric identification or authentication systems as a differentiating or corroborating biometric feature. In addition, the activity of sweat ducts can be seen as a proof of liveness. By stimulating an object such as a finger by blowing air over the skin surface, it is possible to evoke sweat from the sweat ducts. The presence of these small droplets of sweat on the skin surface can be used to locate the position of sweat ducts, using either a spatial or temporal analysis of images of the skin surface. In addition, a temporal analysis can highlight sweat duct activity, which in turn can be used as a proof of liveness.

Abstract: A passive matrix electrophoretic display (1) in which a select driver applies a select waveform to each line of the matrix and a data driver applies a sequence of drive signals (D) to the columns of the matrix according to the image to be displayed on the device. The select waveform includes a reset signal (R1,Rn) which precedes a select signal (S) to be applied to the picture elements of a line of the matrix. The reset signals (R1) may be applied substantially simultaneously to at least a subset of lines of matrix, before respective drive signals (D) are applied to the pixels (2) thereof. Alternatively a select waveform (including the reset signal (RN)) may be applied to each line of the matrix sequentially, with the drive signals (D) being applied to the pixels (2) of each selected line of the matrix whilst the next line is being reset. As a result, the image update line of the device (1) is reduced.

Abstract: In a magnetic resonance imaging system (10), a main magnet (20) generates a substantially uniform main magnetic field (B0) through an examination region (14). An imaging subject (16) generates inhomogeneities in the main magnetic field (B0). One or more shim coils are positioned adjacent a gradient coil (26). The gradient coil (26) is driven in halves by first and second power sources (28, 30) which have slightly dissimilar power characteristics which induce an inductive coupling between the shim coil (60) and the gradient coil (26). The shim coil (60) is designed to produce a desired magnetic field, such that the inductive coupling of the shim coils (60) to the gradient coil (26) is substantially minimized while the inhomogeneities in the main magnetic field (B0) caused by the imaging subject are corrected based on prespecified spatial characteristics.

Abstract: In summary, the present invention provides a method for estimating maximum available write power of an optical storage drive. Optical drives have a certain guaranteed maximum power corresponding to the largest emission angles and worst case electrical parameters of the laser, but many drives could produce more if needed because they are not worst case. The extra power that is available from the lasers that is not worst case is wasted. By identifying drives with lasers that have favorable parameters, the maximum available write power of a drive becomes larger. The present invention solves this problem by providing an estimation method wherein a beam of laser light is generated having a power level (P), a first parameter of the laser light source and a second parameter of the beam of laser light that is generated are measured and used to estimate the maximum available write power.

Abstract: Methods for exchanging signals via a network with nodes (11-15) improve the performance of the network by letting a destination node (12) s receive the signals originating from a source node (11) via different first and second signal routes, and by processing and correlating these signals in the destination node (12). In dependence of a correlation result, a process for processing a signal in a node (11-15) is adjusted. This process may be situated in the destination node (12), or in the source node (11) or an io intermediate node (13-15), in which case a control signal is to be exchanged. A learning algorithm for the adjusting of the process can be run in the nodes (11-15). Label switched routing can be introduced, whereby the label signal is sent from the source node (11) to the destination node via a third signal route different from the first and second signal route, to improve the efficiency of the nodes (11-15).

Abstract: The electronic circuit contains a basic delay circuit (14). A delay is realized by activating the same basic delay circuit (14) a plurality of times in response to a single start signal before generating a response to that start signal. A control circuit (12) receives a start signal and an outputs a response. The control circuit (12) causes a series of signals to be passed through the delay circuit (14), the series starting at a time that is time-continuously triggered by the start signal. Each successive signal in the series starts after a preceding signal has emerged from the delay circuit (12) and the series being terminated after a controlled number of more than one signal has been passed. The control circuit (12) supplies the response upon termination of the series. In one embodiment the series is realized by means of a handshake sequencing circuit (120) that generates a series of successive handshake transactions.
