Abstract: A patient data sensor device has an implantable patient data sensor and an implantable data transmission mechanism, which is in signal connection with the patient data sensor. The data transmission mechanism has an antenna for telemetric data transmission to an external data collection unit. In addition, the data transmission mechanism has a carrier plate for electronic components. The latter are covered on the carrier plate, at least to one side, by a cover. The antenna is configured in an edge region of the carrier plate and running around the latter and around the electronic components. The result is a patient data sensor device which is more tolerable for the patient.

Abstract: A sensor system is used for measuring, transmitting, processing and displaying a brain parameter. The sensor system has at least one implantable brain parameter sensor with a wireless transmission unit for measuring the brain parameter. At least one receiving unit with an antenna is in wireless signal connection with the latter. At least one data read module is in signal connection with the antenna and a data processing and display device is in turn in signal connection with said data read module. The sensor system also has a head cap or a head hood, on which the receiving unit is fixed to predetermine a relative position relative to the transmitting unit. A sensor system is the result, the use of which remains comfortable for the patient even over a relatively long measuring period.

Abstract: A state sensor for plants comprises a clamping device with two clamping elements for clamping a part of a plant. A plant parameter measuring device is coupled mechanically to the clamping device and comprises a sensor element. Said sensor element is configured as a pressure sensor element arranged on one of the clamping elements for detecting a pressure state value of the plant, which pressure state value is independent of the displacement of the clamping elements relative to one another. A watering system has at least one state sensor of this type. A reliable determination of the watering state is obtained over a long period of time and at a low cost.

Abstract: A device (1) is used for measuring brain parameters. This device has a catheter sensor unit (2) which can be implanted distally in a minimally-invasive manner in the parenchyma and/or the ventricles, guided through the cranial bone (4). The sensor unit (2) can be fixed proximally to the cranial bone. For this purpose a proximal circumferential portion of the sensor unit (2) has a self-cutting outer screw thread (5) for fastening the sensor unit (2) to the cranial bone (4). The result is a device which can be fastened in a secure, permanent and at the same time inexpensive manner preventing movement relative to the cranial bone.

Abstract: A probe is used for measuring the oxygen content in biological tissue. The probe comprises at least one optical fibre, which can be proximally optically coupled to a light source on the one hand and to a light sensor on the other. An oxygen-sensitive dye is arranged on and optically coupled to a distal end face of the fibre. A distal fibre portion, including the distal end face, is enclosed together with the dye by an oxygen-permeable, liquid-impermeable membrane which, in the enclosed region, defines a gas compartment surrounding the distal end face with the dye. The probe is a component of a catheter which also comprises a temperature sensor and preferably a pressure sensor. The result is a probe in which the sensitivity of the fibre to disruptive environmental influences at the measuring location is reduced and the scope for interpreting the measurement results is improved.

Abstract: A sensor system serves for measuring, transmitting, processing and representing physiological parameters. The sensor system has least one sensor for measuring at least one physiological parameter. At least one data processing module is in a signal connection with the sensor via a signal cable. A display device serves to represent the sensor data. An expansion module serves to transmit telemetry data. The expansion module may be connected to the data processing module via an interface on the latter. Via a cable-free telemetry line, the expansion module is connected to the at least one sensor or at least one additional sensor for measuring at least one physiological parameter. There results a sensor system in which the patient's freedom of movement is enhanced due to the possibility of using telemetry sensors.
