There is described a design element for a control panel of a device and further a device having a plurality of design elements that can be freely positioned on a control panel, and to a method for configuring such a device and a corresponding computer program. An aim is to provide a control panel which is extremely flexible in its handling. For this purpose, individual design elements are freely positioned on a control panel. Power supply and data transmission to a control module are carried out in a contactless manner. The design elements are preferably printed polymer electronic components having their own electronics.

To monitor functions in a micro-fluidic system having mutually similar parallel fluid paths, sensors () are assigned to the individual fluid paths () at the same respective locations, in order to measure a physical parameter that is influenced by the fluid stream in the fluid paths (). The sensors () are connected to an evaluation device (), which diagnoses a change in the operating state of the micro-fluidic system based on the differences in the parameters measured by the sensors ().

A device for monitoring medication and treatment of patients using a patient card on which the patient's attending physician stores all relevant findings, diagnoses and treatment steps, is in the form of a pocket monitor having a clock or DCF receiver, a plug-in receptacle for the patient card and a reader for the treatment-relevant data as well as a display screen for displaying the readout information relating to the type and time of the upcoming treatments and/or medications.

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.

Ultrasound imaging system having a reduced number of lines between the

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). Preferably, two components can form a common partial system (2) of the transducer device.

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.

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.

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.

Apparatus for transmitting and receiving ultrasonic signals

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.

Stacked slab-shaped support bodies of electrically insulated material are provided with electrodes at one of their side surfaces. In the stack, the electrodes of a support body form the rows of a matrix. The support bodies are each connected detachably to a circuit board on which switchable amplifiers are arranged. In a preferred embodiment, the switchable amplifiers are dual-gate MOS-FETs, the first gate terminals of which are each connected electrically to an electrode of the support body.

An ultrasonic transducer comprises a support body, a piezoelectric layer of a material with a relatively high dielectric constant and high acoustic impedance, a first impedance matching layer and a second impedance matching layer (10). The first matching layer consists of silicon.

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.
