Abstract: A radio communication device (1) comprises a Radio Frequency (RF) unit (2) for transmitting and receiving radio signals, a link controller (3) for controlling operation of the RF unit (2) and a signal monitor (4) for monitoring signals received by the RF unit (2). A processor (5) is connected to the link controller (3) and the signal monitor (4) and a user interface (6). When it is desired for the communication device (1) to communicate with another device (9), a communication link is established in a conventional way. The signal monitor (4) is able to measure signal strength and the bit error rate (BER) of the signal received in the communication link from the other communication device (9) and outputs these to the processor (5). When the BER is unacceptably high, the processor (5) determines whether the measured signal strength has changed from very high to very low in a short period. This is indicative of the body (10) blocking the signal.

Abstract: A shuffle device for players with different types of storage medium such as CD, DVD, hard disk drive or random access memory. The shuffle device is provided in a particular central control device such as a remote control, a hand-held computer, a personal digital assistant or palmtop that is valuable for all the players of the (home) system. As the shuffle device includes hardware and software, thus such hardware and software are needed only once and can be used for different players using a single shuffle device, for example. This alleviates the need for each player to have its own shuffle device thus reducing the cost of each player. Meta data that are downloaded from the Internet, derived from a smart card, added by means of a voice-to-text-converter, or typed in by the user may be displayed on the central control system.

Abstract: A diagnostic imaging apparatus generates a three-dimensional diagnostic image representation. The image representation is converted into an image representation of the patient's heart. A left lower posterior point of the heart image representation is selected as a first approximation of a left ventricle apex and a line of preselected orientation is drawn through the first approximation apex as a first approximation ventricle axis. The ventricle axis is redefined by generating short axis slices across the approximated ventricle axis, isolating a selected one of the ventricles, determining a centroid of each short axis slice of the selected ventricle, and fitting the axis to the apex approximation and the centroids. The apex location is redefined by looking for the lowermost short axis slice orthogonal to the redefined axis which intersects the ventricle volume and selecting the intersection point as the next approximation of the apex.

Abstract: Image registration very often used to be a tedious task which had to be performed manually. According to an exemplary embodiment of the present invention, a registration of image time series is performed on the basis of a pharmacokinetic model in which alternative translation sequences of a region of interest are compared to each other on the basis of the pharmacokinetic model and the best translation vector sequence is used for image registration. Advantageously, this may allow for an effective compensation of organ movement, even if there is no or only little anatomical contrast.

Abstract: A fluorescent lamp (2), in particular a backlight lamp of a display device, is supplied with an alternating voltage, a frequency and an amplitude of which being greater during ignition than during normal operation of the lamp. The voltage (V) across the lamp and the current (I) through the lamp are measured to provide a measured voltage value and a measured real lamp current value. From the alternating voltage there is derived a voltage (V2). The measured voltage value is multiplied by the sum of the measured real lamp current value and the derived voltage. The multiplication result (P=V*(I+V2)) is compared with a reference value (Ref), which results in a difference or error value. The error value is used to control the frequency and the amplitude of the alternating voltage (V), such that the error value is minimized.

Abstract: The invention relates to a helical cone beam computed tomography method wherein a radiation source moves along a helical trajectory with respect to an object in a nPi relative movement. Measured values are partially differentiated with respect to the angular position of the radiation source on the helical trajectory, and intermediate filter values are generated by filtering along filter lines with a ?-filter. Each of the intermediate filter values is multiplied by a filter factor wherein the filter factor for intermediate filter values, which have been generated by filtering along filter lines running only within the Pi window, is larger than or equal to filter factors, by which intermediate filter values are multiplied, which have been generated by filtering along filter lines running within and outside the Pi window. Intermediate filter values generated for a measured value are added to a final filter value, and the final filter values are back projected to reconstruct an image of the object.

Abstract: The invention relates to a data processing system and a method for synchronizing data traffic. The invention relies on the perception that the lack of synchronization of data traffic is primarily caused by the use of different schemes for reservation of resources. According to the invention, a conversion unit is provided which converts first data into second data, the first data being controlled by a first scheme for reservation of resources and the second data being controlled by a second scheme for reservation of resources. The conversion unit may be referred to as a network-level bridge (NWB). For example, the different schemes for reservation of resources may be based on slot tables, in which case the conversion unit converts the slot assignments for the first data into the slot assignments for the second data.

Abstract: The present invention relates to a recording apparatus, record carrier and method of recording data on at least two layers of a recording medium by using a radiation power, wherein individual recording speeds are determined for respective ones of the at least two layers at different values of the radiation power. A recording speed to be used for recording on an individual one of the at least two recording layers is selected based on a maximum radiation power specified for the recording operation, and the speed of the recording operation is controlled individually for each of the at least two layers based on the selected recording speed. The determination of the individual recording speeds at different radiation power values may be written or embossed on the record carrier. Furthermore, a recording sequence used for recording on the recording layers can be set based on the sensitivities and thus recording speeds. Thereby, total recording time can be minimized for multi-layer recording media.

Abstract: The present invention relates to a method and a system of recognizing an ear by locating an invariant point in a representation X of ear geometry. An idea of the present invention is the improve the well known Iannarelli algorithm in that the scheme of the present invention captures and processes all pixels values along an axis and may use an arbitrary number of axes to combine these pixel values to a complete feature vector with a sufficient level of discrimination. The prior art Iannarelli method is improved by performing a Fourier transformation of a polar representation e[?, p] of the ear, whereby a transformed E[?/P] polar representation is created. This transformed representation is sampled to create an ear feature vector XF.
