Abstract: A system for generating a humanly perceptible signal at one or more predetermined points in time, at which one or more medications must be taken or a time-dependent medical procedure must be implemented, includes a control unit at which the time or times are stored, and which includes a time measuring unit which provides a signal upon the occurrence of the time or times, and at least one signaling device disposed remote from said control unit, which receives a signal via a communication system from the control unit and which emits a visually perceptible reminder upon receipt of the signal. The control unit and the signal device are disposed in a building which is occupied, or can be occupied at times, by a patient, and the communication system is integrated as a part of the building.

Abstract: An ultrasound imaging system has a probe containing a 2-D array of transducer elements and a base unit for the phase-delayed driving of the transducer elements of the array. Transmit pulsers digitally controlled by the base unit are provided for the transducer elements in the probe, and an address decoder is provided for the transmitting state, and a multiplexer for the ultrasonic signals in the receiving state. For the transmitting state, the probe and the base unit are interconnected via digital control lines and, for the receiving state, via a number of signal lines that is reduced by the multiplexer factor of the multiplexer.

Abstract: An ultrasound transducer device with a one-dimensional or two-dimensional array of transducer elements (4.sub.j) has at least one plate-shaped component. This component contains an acoustical attenuation element (3), at one narrow side (3c) of which the transducer elements (4.sub.j) are arranged with piezoelectric oscillation elements and electrodes, as well as an electronic circuit part (17a) and connection leads (10a) between this circuit part and the electrodes. An electrode is arranged at each transducer element (4.sub.j) between its oscillation element and the attenuation element (3), which has a connection part for the connection leads (10a) which leads to a broad side (3a), and a strip-shaped carrier element (14) is connected with the attenuation element (3), with the electronic circuit (17a) located on the one broad side. Cooling channels (20, 21) may be used as a means for cooling the carrier element (14, 14.sub.k).

Abstract: An ultrasound sensor is used for measuring the sound pressure amplitude in the focal range of focused ultrasound shock waves. The sensor contains a polymer foil which is piezoelectrically activated in one region and is coupled to electrodes which are physically separated from the region. The polymer foil is arranged in a hollow plastic cylinder with its flat surface sides parallel to the central longitudinal axis of the hollow cylinder. By this measure, interfering diffraction effects are reduced and miniaturization of the ultrasound sensor is achieved.

Abstract: A method for the self monitoring transducer in which approximate calibration of the transducer does not require physical disconnection of the measuring chain so that the transducer need not be uncoupled to be measured. The method permits monitoring the transducer during its operation by modulating at least one predetermined quantity h.sub.i with a suitable actor. The measuring signal associated with the individual modulation quantities are used to monitor and calibrate the transducer.

Abstract: An apparatus for transmitting and receiving ultrasonic signals for an ultrasonic imaging device operating by the pulse echo method. There is arranged next to a linear array of ultrasonic transducer elements serving as ultrasonic transmitter, a matrix type array of ultrasonic transducer elements serving as ultrasonic receiver, the columns of which run parallel to the longitudinal direction of the linear array. By the use of the matrix type array of ultrasonic receivers it is possible to receive echo signals from a wide angle range and to discriminate them with respect to their scattering angle.

Abstract: A self monitoring pressure transducer includes a reference chamber, that transmits the pressure through a fluid medium to the flat side of a diaphragm, using a piezoelement, arranged in the reference chamber, as an electrically controllable actor. The piezoelement can modulate the pressure in the reference chamber by a predetermined quantity. The modulation of the measuring signal associated with this pressure modulation permits self-monitoring of the pressure transducer while it is in operation.

Abstract: An ultrasonic head is a linear array consisting of a plurality of transducer elements. The array is perpendicular to a sectional plane of the object under study and can be rotated about its longitudinal axis. Several groups each consisting of jointly controlled transducer elements are driven to form a beam aperture. Between each two adjacent driven groups there is provided at least one group that is switched off. The ultrasonic tomography unit thus obtained scans several parallel section levels one after the other or even, at least approximately simultaneously, without additional mechanical movement.
