Abstract: A device for the transmission and/or reception of RF signals for magnetic resonance imaging (RF coil system) is constructed as an RF coil (body coil) which is permanently mounted in a magnetic resonance imaging apparatus or as a so-called dedicated RF coil (that is, as a separate RF coil which is to be arranged on or around a region to be examined, for example, a head coil, a shoulder coil, a flexible surface coil etc.). A magnetic resonance imaging apparatus includes an RF coil system of this kind. The RF coil system includes a plurality of resonant conductor elements (201, 202, . . . , 208; 211, 212, . . . , 218), notably ?/4 monopole elements. In comparison with known RF coil systems of the same length, a substantially larger field of view as well as a constant variation and a steeper drop of the field characteristic are thus achieved at the edges of the RF coil system while the construction remains comparatively simple and economical nevertheless.

Abstract: A portion of an object is subjected to a T2-preparation sequence. The portion of the object is subjected to a 2D navigator restore sequence. Subsequent to subjecting the portion of the object to the 2D navigator restore sequence and T2-preparation sequence, the portion of the object is subjected to a 2D navigator sequence. A MR navigator signal is measured. A series of MR imaging signals is generated by subjecting the portion of the object to an imaging sequence. The MR imaging signals are measured for reconstructing an MR image.

Abstract: A system calibrates a solid state detector (20) for a radiation imaging device (10) in a single acquisition. A calibration phantom (40) emits radiation concurrently at at least first and second characteristic energy levels. A nuclear camera (16) generates associated sets of radiation data spanning both the first and second energy levels from the emitted radiation that is received by solid state detector (20). A means (64) determines associated centers of energy peaks and energy values of the generated data sets. A calibration means (80) calibrates at least one of gain, offset, performance and dead pixel correction based on the determined centers and peaks of the acquired data sets.

Abstract: A system and method for representing a person in an electronic system. An image is obtained including an image of a target person. The image or a digital representation thereof, is processed to recognize a facial feature associated with the target person in the image. The target person's facial portion is then extracted from the image. The extracted target person's facial portion is displayed via a display interface associated with a same or separate and distinct electronic system to represent the target person when connected to that electronic system. An image capture device capturing the image obtained is adapted to take an image at a moment when a target person is smiling or when a target person is gazing towards capture device. An icon may be generated that includes the extracted target person's facial portion for representing the target user via a display interface associated with the electronic system.

Abstract: A method is proposed for a mobile terminal in mobile communication systems to transfer non-speech data in voice channel, comprising steps of: encapsulating the non-speech data to be sent to another mobile terminal into IBD frames; storing said IBD frames in a buffer; detecting whether a speech burst sent to said another mobile terminal is over; checking whether there is non-speech data to be sent to said another mobile terminal if detecting that said speech burst is over; sending at least one non-speech data to said another mobile terminal via voice channel if there is non-speech data to be sent. By modifying the SID frame and silence speech frame, this method realizes transmission of non-speech via voice channel rather than via dedicated data channel, so as to save radio resources of the system.

Abstract: A cyclic rail-stabilized method of driving an electrophoretic display device (1), wherein a substantially dc-balanced waveform is used to effect various required optical transitions. The driving waveform consists of a sequence of picture potential differences, which cause the charged particles of the electrophoretic display device (1) to move cyclically between extreme optical positions in a single path, irrespective of the image sequence required to be displayed, except in the case where the desired optical transition is from an intermediate position (or grey scale) to the extreme optical position (or rail state) closest to that intermediate position, in which case the optical transition is effected substantially directly by means of a single voltage pulse (20) which is substantially equal in amplitude and duration, but of opposite polarity, to the voltage pulse (30) required to effect an original optical transition from the rail state to that grey scale.

Abstract: The invention relates to a backlighting arrangement for a light valve display device, such as an LCD-display. The backlighting arrangement comprises a number of elongated light emitting structures (9) arranged in a layer (5), extending in a plane, which structures emit light along their lengths in the direction of a light valve layer (1). An optics layer (7), comprising a number of elongated lenses (11), is placed between the light emitting structures (9) and the light valve layer (1). Each such lens (11) concentrates light emitted by a number of light emitting structures (9) onto a number of elongated areas on the light valve layer (1). Preferably, each light emitting structure (9) emits light of one primary colour only, and the elongated lenses concentrate the light emitted from each light emitting structure onto sub-pixel areas intended for a corresponding colour, so that a colour display may be provided without the use of colour filters.

Abstract: A communication device G is arranged to delay a procedure for joining a network (1) until it detects activity (23) on the network (1), for example until the communication device G is within range of network (1). In response to a positive detection of network activity (23), the communication device G broadcasts its address to other communication devices A-F already connected to the network (1). In response, a message (27) containing a list of addresses of the other communication devices A-F is sent by a selected one of the other communication device, for example, the one communication device F that most recently joined the network (1). Each communication device A-G is arranged to send a message (27) once, so that only one message (27) containing the address is sent to a communication device G joining the network (1). If no network activity (23) is detected, the communication device G may continue to broadcast its address (26) periodically at gradually increasing time intervals.

Abstract: In a method for shimming a magnetic resonance imaging scanner (10), at least one of fat suppression and blood suppression is performed to suppress magnetic resonance from a corresponding at least one of fat and blood. First and second magnetic resonance echoes emanating from a generally columnar volume are measured. The measurements of the first and second magnetic resonance echoes (122, 124) are reconstructed (150) into corresponding first and second generally columnar projection images (152, 154). The first and second generally columnar projection images are combined (160) to produce a magnetic field profile (174) of the generally columnar volume. Selected magnetic field parameters are extracted (142) from the magnetic field profile. Shim currents are computed (180) from the selected magnetic field parameters. The shim currents are applied to magnetic field coils (16, 60).

Furthermore, the thickness and/or height of the foils between rows may be different from the thickness and/or height of the foils between columns.

Each unit is provided with stabilizers (23, 23?; 24, 24?) which are situated at the ends of said emission surface and lie in the plane P as well, thus preventing turning of the unit around an axis A normal to the plane P.

Abstract: Bit level, rather than symbol level, diversity combining is employed within a wireless communications receiver. Channel estimates and bit metrics are separately computed for signals received by different antenna elements. Bit metrics are calculated by determining a least squares cumulative difference between all bits within the received symbol and corresponding bits within constellation symbols as modified by the channel estimate. The separately-determined bit metrics are then combined for decoding. Performance improvements over both single antenna systems and multiple antenna systems with symbol level diversity combining are achieved.
