Abstract: The invention relates to a sensor instrument (2) for examining the mucous membrane of the oesophagus, stomach and duodenum of a patient to see whether it is infected with bacteria. Said instrument comprises an evaluation unit (4) and a catheter probe (6) with an ammonia-sensitive sensor (8) and a catheter.

Abstract: A computer network system and a method for quality testing input clinical trial data are disclosed. The trial data is recorded by way of a form provided on a patient device or a physician device and is passed on in an encrypted, anonymized form to a central server. A quality testing device is installed on the server in order to test the recorded medical data sets with regard to the quality thereof. The scope of the quality test is configurable. In the event of successful testing, an incentive attribute is read out from a database in order to generate an incentive signal and to transmit the signal to the respective terminal device.

Abstract: An arrangement for navigating an endoscopic capsule includes an external first magnetic field with a first magnetic flux density for moving the endoscopic capsule. The arrangement also includes at least one sensor coil pair outside of the endoscopic capsule for determining a position and/or orientation of the endoscopic capsule. The at least one sensor coil par includes a first sensor coil and a second sensor coil. The first sensor coil and the second sensor coil are electrically connected to one another and arranged at locations with the same first magnetic flux density.

Abstract: A method for producing a scattered radiation grid for x-ray radiation by stacking strips and an associated scattered radiation grid are provided. The strips are cut out of a laminate that includes a first layer, a second layer, and a third layer. The first layer is formed from a first material that absorbs x-ray radiation, and the second layer is formed from a second material that is permeable to the x-ray radiation. A second material that is highly permeable to the x-ray radiation and reduces the attenuation of the scattered radiate on grid may be used.

Abstract: A magnetically guided endoscope system has a display system wherein the position of the boundary of the examination region of the magnetic field that is used for capsule endoscope guidance is displayed and/or the position of the peak of the magnetic field used for capsule guidance is displayed. The displayed information can be presented in the form of computer-generated graphics superimposed on a camera image of the patient by a computer, or can be a fixed indicator on the display screen of a display at which a computer causes the camera image of the patient to be displayed at a position that is correctly oriented with respect to the fixed information.

Abstract: A method for operating a linear compressor including a linear drive with a stator and a rotor configured for displacement by a magnetic field of the stator against a spring force, and a compression chamber which is delimited by a displaceable piston coupled to the rotor during the operation of which an alternating current is applied to the stator in order to drive the rotor in an reciprocatingly, the method including the steps of applying, prior to operation, a direct current with a first polarity to the stator in order to displace the rotor from a rest position, measuring a first end position attained by the rotor under the action of the direct current, and controlling, during operation, the intensity of the alternating current with which the stator is excited in a manner wherein the rotor does not reach the first end position or reaches it at a reduced speed.

Abstract: Prior art discloses gas bearings, which use a stream of gas to support a piston. This is achieved by micro-nozzles in the cylinder wall of a cylindrical element. Micro-nozzles of this type are susceptible to dirt retention. According to the invention, channels that run parallel with the cylinder axis are provided on the inner face of the base element, some of the channels supplying gas via the compression chamber and the other channels being connected to the gas reservoir.

Abstract: A reversing linear drive which comprises a field coil and a magnetic armature that is excited by the magnetic field of the field coil to perform a linear, axially oscillating movement. In order to detect the armature position, the drive is provided with a stripe pattern element with an alternating arrangement of transparent and opaque stripes or of light-reflecting stripes and non-light-reflecting stripes which extends at least across the entire axial armature stroke, and with a light barrier with elements that emit and receive light in a direction perpendicular to the axial direction.

Abstract: Known compressors are equipped with gas bearings, in which the bearing nozzles are continuously supplied with a stream of gas. According to the invention, the gas bearing is a self-sufficient bearing, in which the supply pressure is independent of the delivery pressure. To achieve this, the compressor is equipped with a gas reservoir with a bearing supply pressure.
