Abstract: A high-voltage connector is described, having a plug (10) with a rubber cone (131; 132, 133) for insertion in a socket (20). A connector of this kind is also referred to as a rubber-cone plug system and is used in particular for connecting X-ray generators to high voltage generators. The connector is characterized in particular by the facts that the rubber cone has a first portion (131) having a first angle of application (A) in a tight-fitting joint (14) and at least one second portion (132, 133) having a second angle of application (B) in the tight-fitting joint, and that respective female contacts (16, 17), into which contact pins (23, 24) for making contact with the high voltages extend, are incorporated in each second cone portion (132, 133). The first angle of application (A) is preferably greater than the second angle of application (B) in this case, thus causing good insulation against high voltages to be ensured by a high applied pressure from the plug.

Abstract: The invention relates to a magnetic-resonance imaging (MRI) apparatus comprising an electrical coil system (17) for transmitting and receiving a radio-frequency (RF) magnetic field from an examination volume (3) of the MRI apparatus. The electrical coil system (17) comprises at least one surface coil (35) which extends substantially in a plane. The surface coil is used for transmitting and/or receiving a RF magnetic field which is oriented substantially perpendicularly to the plane of the surface coil (35).

When the MRI apparatus is in use, the main coil axis (37) extends substantially parallel to a main magnetic field in the examination volume (3) of the MRI apparatus. On both sides of the main coil axis (37), the surface coil (35) comprises an electrically conducting element (39) which extends substantially parallel to the main coil axis (37).

Abstract: An Y-ray detector apparatus comprises an array of detector pixels arranged into a plurality of sub-arrays. The pixels in each sub-array share a common dose sensing output provided to a dose sensing output conductor which extends to a periphery of the pixel array. The dose sensing output conductor for one sub-array of pixels passes through the area occupied by another sub-array of pixels, which can lead to unwanted cross talk. The invention provides a plurality of additional screening electrodes, with a screening electrode substantially adjacent the dose sensing output conductor for each sub-array of pixels. These screening electrodes reduce cross talk between the dose sensing output and other pixel electrodes. In another arrangement, each pixel further comprises a pixel electrode for each pixel formed at an upper region of the array, and the dose sensing output conductors are formed at a lower region of the array.

Abstract: In an active matrix electroluminescent display device a storage capacitor (24) is provided in each pixel for storing a voltage to be used for addressing a drive transistor (22) which controls the illumination of the electroluminescent display element (20). A discharge photosensitive element (34) is provided for discharging the charge storage capacitor in dependence on the display element's light output. A further photosensitive element (40) is provided so as to cancel photocurrents produced in the discharge photosensitive element (34) as a result of light input to the discharge photosensitive element other than from the pixel's display element (20), the further photosensitive element being shielded (44) from light emitted by the display element while being exposed to light from other directions. Irregularities in the display output due to the effects of the unwanted light inputs to the discharge photosensitive elements are then avoided.

Abstract: A radio frequency receive coil for receiving a magnetic resonance signal includes a radio frequency antenna. The radio frequency antenna includes one or more electrical conductors (72, 74, 76, 78, 172, 173, 176, 180, 252, 254), at least one of which is a substantially hollow conductor (72, 78, 172, 252, 254). At least one electrical component (100, 110, 110?, 110?, 140, 160, 200) is mounted to be shielded from interfering with the MR signal by disposing it inside the substantially hollow conductor. The at least one electrical component can be, for example, a battery (100, 160, 200), a storage capacitor (140), or coil electronics (110, 110?,110?).

Abstract: A method for calculating total left ventricular (LV) volume during a cardiac cycle includes estimating the LV volume using only endocardial contours in a cardiac 3D image that was acquired at end diastole (ED), i.e. the moment at which the heart is fully relaxed. These contours are manually specified or (semi-)automatically derived. Based on these contours and on the pixel intensity in all other images, the LV volume is estimated based on intensity variations within the area enclosed by the contours (ED LV blood pool) . These variations are proportional to the change in size of the ventricle. Hence ventricle volume and other derivable cardiac functionality parameters as well as the phase in the cardiac cycle are derived.

Abstract: A method and system for embedding an authentication signature in an audio-visual signal such that only a part of an entire frame of the audio-visual signal is stored in a memory while the signature bits are calculated and the watermark is embedded. A signature is formed based on a first portion of said audio-visual signal, whereby said first portion is a pattern of horizontal lines of said audio-visual signal and has fewer lines than the number of lines of the entire audio-visual signal. Thereafter the signature generated is embedded in said audio-visual signal in the first portion and/or in another portion of the frame to be authenticated, whereby the other portion also is a pattern of horizontal lines. Thus only memory for some lines instead for all lines of the audio-visual signal is needed. In the case of an interlaced audio-visual signal, the first portion is preferably the first field of a frame of said audio-visual signal and the second portion is the second field of said audio-visual signal.

The multimedia content item comprises a plurality of segments. At least one segment of the multimedia content item is selected, step (107), to generate a summary, step (109), which has a pace similar to the perceived pace of the multimedia content item determined in step (105).

Abstract: A transmission path (13) for transmitting high frequency (RF) signals is disclosed, which comprises a plurality of lead segments (20, 21, 22) which are coupled to one another on one end by a capacitive coupling element (30) and on the other end by an inductive coupling element (31) and which each have an effective length of approximately ?i/4, wherein ?i is the wavelength of a differential mode signal to be transmitted over the path (13). By providing these element (30, 31) in the form of distributed elements which electrically extend over at least a part of adjacent lead segments (20, 21; 21, 22) a very thin transmission path (13) can be realized, which is especially suitable for use with invasive catheters. Furthermore, this path (13) can be guided through RF fields of a magnetic resonance (MR) imaging system because common mode resonances are effectively suppressed.

Abstract: The surface detection system includes a source of an optical interrogating signal (44) which accompanies a droplet spray in an oral cleaning device directed to an oral surface (46). The interrogating optical signal is reflected from the oral surface which the spray impacts and detected (48). A selected characteristic of the reflected signal, such as intensity, is indicative of the nature of the oral surface, such as either gum tissue or a tooth surface. The detected reflected signal is then processed to determine the nature of the oral reflecting surface. The processor (50) then provides a resulting output signal which can be used to either warn the user concerning the nature of the oral surface or to change the characteristics of the spray appropriately according to the surface (51).

Abstract: A colour reflective display device uses two colour absorbing components (40,42), and the quantity of the two colour absorbing components within the pixel aperture can be independently controlled. The first colour absorbing component has a colour (C) at a point lying substantially between the green and blue regions of an (x,y) chromaticity diagram, and the second colour absorbing component has a colour (O) at a point lying substantially between the green and red regions of an (x,y) chromaticity diagram. The invention provides a colour active light shutter layer with only two colour components. One is selected to be near cyan and the other is selected to be near orange, and these together enable a range of colours to be produced which enables good quality colour images to be produced.
