Abstract: A catheter for measuring a flow of blood through a body tissue comprises a light emitter for emitting light into the body tissue and at least one light receiver for receiving light reflected in the body tissue and back to the catheter. The light emitter and the at least one light receiver are arranged in the catheter, wherein the catheter comprises a middle piece and a first and a second connection tube. The middle piece has a distal fastening piece for fastening to the first connection tube and a proximal fastening piece for fastening to the second connection tube, wherein the light emitter and the at least one light receiver are arranged in the middle piece.

Abstract: A device for measuring the blood flow of a body tissue comprises a catheter having a catheter head for the insertion into the inside of a body tissue and a center piece having a light emission surface, out of which an optical conductor leads, and having a reflection surface, which is disposed opposite of the light emission surface and oriented obliquely to the longitudinal axis of the optical conductor. The optical conductor is disposed such that an emitted light beam is directed at the reflection surface, the emitted light beam can be deflected at the reflection surface and reflected into the body tissue, and a reflected light beam can be reflected out of the body tissue at the reflection surface and fed into the optical conductor. The catheter head is divided into an insertion region and a connecting region, wherein the insertion region comprises a plurality of recesses on the surface thereof. In the direction of the connecting region, the insertion region has an increasing diameter.

Abstract: The device claimed by the invention is characterized essentially in that during the transport of a flat object, in particular, a banknote, through guide elements the deflection of one or two second guide elements from a first guide element is detected via an electrically conductive element by one or more flat air core coils. In the process a magnetic alternating field is generated which is influenced by a change of position of the electrically conductive element. The alternating field causes eddy currents in the electrically conductive element. These eddy currents in turn influence the alternating field. When the flat coils are each a part of an LC oscillating circuit, for example, the resonance frequency and the attenuation of this oscillating circuit are influenced. At a constant excitation frequency the amplitude of the oscillations varies.

Abstract: The invention relates to a scale having a base plate (1), a bed plate (2) located at a distance above the base plate (1) for supporting an object to be weighed, and elastic spacing elements (3) located between the base plate (1) and the bed plate (2). Said scale further comprises a weighing means for determining the weight of the object, said weighing means being at least one inductive proximity sensor (10, 20, 4). Said scale is robustly constructed and allows great flexibility in the external design of the scale.

Abstract: The invention relates to scales comprising a bearing surface for supporting a load to be weighed, an electroconductive sensor plate, a flat coil arranged at a distance from the sensor plate and used for the inductive measurement of a distance between the sensor plate and the flat coil, a housing surrounding the sensor plate and the flat coil, and a push-button which protrudes out of the housing and is connected to the sensor plate. The inventive scales are easy to assemble but also versatile.
