Abstract: An ultrasound probe includes a transducer array which is moved back and forth to sweep the image plane of the array through a volumetric region for 3D scanning. The transducer array is mounted on a carriage assembly which moves back and forth on a pair of rails inside a fluid compartment in the probe. The rails are preferentially arcuately curved to provide an elevationally divergent scan with a relatively wide aperture in the near field. A cam is provided for a motor-driven cable drive for the carriage assembly which provides relatively linear motion through the path of travel of the transducer array.

Abstract: An electrophoretic display comprises a pixel which has a pixel volume comprising a reservoir volume and an image volume. Particles which have different colors and different electrophoretic mobilities are present in the pixel volume. An amount of the particles present in the image volume determines a visible color of the pixel. Select electrodes generate in the reservoir volume a select electric field which separates the particles in different sub-volumes in the reservoir volume. Fill electrodes generate a fill electric field to move the particles from the different sub-volumes into the image volume.

Abstract: When a program of a certain duration is converted into compressed data (encoded), it is desirable for the total number of data to fit in an available data space, for example, when recorded on an information carrier. More particularly in variable bit rate compression such as a video signal via MPEG-2, this is hard to forecast. For this purpose, a recording device according to the invention comprises a compression unit (22) whose bit rate is influenced by a system controller (45) via a control input (26) during the encoding process in dependence on the remaining part of the vacant data space on the information carrier (1) and the remaining duration of the program. When parameters influencing the bit rate are set in the compression unit (22), the system controller will take the complexity of the program derived during a previously encoded part of the program into account.

Abstract: A nuclear camera (10) includes a plurality of detector heads (12) which have collimators (14) for fixing the trajectory along which radiation is receivable. A rotating gantry (22) rotates the detector heads around the subject collecting less than 360° of data, e.g., 204° of data. A zero-filling processor (50) generates zero-filled projection views such that the actually collected projection views and the zero-filled projection views span 360°. A smoothing processor (56) smooths an interface between the zero-filled and actually collected projection views. The zero-filled and smoothed views are Fourier transformed (60) into frequency space, filtered with a stationary deconvolution function (62), and Fourier transformed (64) back into real space. The resolution recovered projection data sets in real space are reconstructed by a reconstruction processor (68) into a three-dimensional image representation for storage in an image memory (70).

Abstract: A method is described for setting an optimum recording power level for recording information on an optical record carrier. First a series of test patterns is written on the record carrier with a different recording power. On reading the test patterns, the jitter values of each read signal is determined. The jitter as a function of recording power is approximated with two linear functions. The optimum recording power level for the record carrier is derived from intersection of the functions. The invention relates also to a device arranged to perform the method. The invention further relates to an optical record carrier comprising the optimum recording power as determined by the method according to the invention.

Abstract: A wireless remote control unit (60) that operates in the radio frequency bandwidth is used for interfacing with a sequence control system (B) and an image processing system (C) from within a magnetic resonance suite (A) in the presence of a magnetic field produced by a main magnet assembly (10). The sequence control system and the image processing system are connected with a first wireless transceiver (30) whose antenna (28) is located within a magnetic resonance suite. The first transceiver (30) communicates with the remote control unit (60) and a second transceiver (32) connected with a transmitter (40) and gradient coil amplifiers (34). Resonance signals received by a radio frequency coil (46) are communicated to the first transceiver (30) by the second transceiver (32) or by a transceiver (46?) mounted on the receiving coil. The receiver coil transceiver also engages in a handshake protocol to identify itself.

Abstract: An optical head scans the information layer (3) of an optical record carrier (1) by means of a radiation beam (13). Optical aberrations in the beam such as coma and spherical aberration, caused by tilt and thickness variations in the optical disc respectively, are compensated by an aberration compensator (27) arranged in the radiation beam. The tilt or thickness variation is measured by a detector (30) and used to control the aberration compensator. The radiation beam is focused onto the information layer by an objective system (11). A displacement of the objective system in the transverse direction (26) as used for radial tracking of the optical beam, causes a mismatch between the wavefront to be compensated and the wavefront introduced by the aberration compensator (27). The detrimental effects of the mismatch are reduced by compensating only part of the aberration. The degree of compensation depends on the maximum displacement of the objective system and the tolerable wavefront error.

Means are used for composing the training corpus from the selected documents.

Abstract: A digital signal is interleaved by delaying samples thereof by an integral number times a unit delay in accordance with a cyclically repeated delay pattern (AL91) . . . AL(M) Select lines (AL91) . . . AL(M)) of a memory (HAS) are cyclically activated (HAS) at a cycle rate equal to unit delay. During the activation of a select line, both data is written and read from the memory. The data written comprises a relevant bit of each sample to be delayed in an integral number of sample groups. Each sample group is associated with one delay pattern cycle. The data read (b(1,1,j)@a1 . . . b(1,M,j)@aM . . . b(k,1,j)@a1 . . . b(k,M,j)@aM) comprises a number of bits which is equal to the number of bits written. The bits are read in accordance with the delay pattern. Accordingly, the speed requirements imposed on the memory (MEM) are relatively lax.
