Abstract: A scanned 2- or 3-D modulated light pattern originating from a light source and represented by a matrix of pixels is projected onto a defined surface or into a defined region distant from the light source. A plurality of means (88) for modulating light one operated between at least a first mode and a second mode. This operation is synchronised with the scanning of the matrix of pixels so that: 
a) respective modulating means (88) is in the first mode when its associated plurality of pixels are being scanned; and b) a respective plurality of pixels are not being scanned when its associated modulating means (88) is in the second mode. When a modulating means (88) is in the first mode, it allows light to be distributed from the defined surface or the defined region. When a modulating means (88) is in the second mode, it allows the effect produced by any light incident on the defined surface or in the defined region to be reduced.

Abstract: An ultrasonic blood flow measuring and imaging system comprises a transmit-receive transducer for transmitting ultrasonic waves toward and into the human body and for receiving reflected echo signals which are then processed for use in a Doppler blood flow imaging and display system. Multiple ultrasonic pulse beams are transmitted into the body at each of a number of locations in an area under diagnosis. For each location a plurality of reflected echo signals are received during successive predetermined time intervals. Each received echo signal has a stationary component reflected from essentially stationary tissue and a Doppler component reflected from areas where movement is sensed, such as blood flow. The reflected echo signals are processed in a canceller having stationary signal acquisition and Doppler signal acquisition modes, in that order, for each flow measuring sequence. In the stationary acquisition mode, an ultrasound basis line is first transmitted, its echo detected, amplified, converted to digital, and then stored in a line buffer. The system then switches to the Doppler acquisition mode, and on each of the succeeding pulses the stored line samples are recalled from the line buffer, converted to analog form, and subtracted from the succeeding reflected echo signals. The difference is amplified, converted to digital, and processed by an MTI filter to thereby produce Doppler flow image data for use in imaging, including color imaging, of blood flow in the area under diagnosis.

Abstract: Track following servo patterns are written to the disks 14 of a DASD unit after the unit has been completely assembled, using the DASD's voice coil motor and transducing head assembly 32, 34, 36, 37. Before assembling the DASD unit a servo reference surface is recorded on one of the disks. This reference surface contains the track following servo patterns and the clocking information that is required for subsequently recording servo patterns on the recording surfaces of all of the disks. After the DASD unit has been fully assembled, and sealed, its access motor and transducing head assembly is used to read the reference surface. Thereafter servo patterns are written to the remaining disks, again using the DASD's access motor and transducing head assembly. The servo reference surface may be recorded on one of the disks during full surface testing of the disks thereby eliminating the need to use a servo writer.

Abstract: In a liquid-application unit operating according to the refilling principle, the liquid which is to be fed via hoses is to be distributed uniformly over the working width. This took place previously by means of a reservoir space which is advantageously formed from a conically increasing retaining space, out of which the liquid runs onto the material web via an overflow edge and a guide surface. However, it is also essential with this low-volume liquid retaining space that the liquid be supplied uniformly over the working width, in particular when changing colour. In order to achieve this, individual liquid distribution spaces which extend one directly next to the other over the working width are defined in which uniformity is achieved by means of a forced distribution of the liquid from a feed opening to a number of outflow openings. This forced distribution takes place similarly to the structure of a family tree, namely in steps from one opening to two, four, eight, sixteen outflow openings and so on.
