Abstract: The embodiments relate to a sensor strip (13) and to a flexible support strip (12) for receiving the sensor strip and for fixing the strip to a surface e.g. to the back of a test person. According to the embodiments, the sensor strip (13) has a reference point (18), (for example a snap fastener connection), with which it can be fixed to a reference surface (16) of the support strip. This allows the position of the sensor strip (13) to be unambiguously defined on the support strip (12). The further extension of the sensor strip (13) lies in a pocket (23) so that it can slide, allowing the relative movement between the support strip and the sensor strip if the support strip is lengthened (represented by a dot-dash line). The entire sensor unit is thus advantageously more comfortable to wear, as the elastic support strip (12), for example, can freely follow the back movements of the test person.

Abstract: The profile of the spinal column and changes in the profile of the spinal column are continuously measured during movement along the entire spinal column in all degrees of freedom of its deformation.

Abstract: In a method for the production of optical bands with several optical fibers, the surface of the optic fibers in said bands is treated such as to increase the optical damping in sections of the optic fibers. The generated damping may be reliably adjusted, whereby during (or after) the processing of the surfaces a measuring light is introduced into the fiber optic and the light output at the other end of the band is measured by means of a sensor such as a CCD camera. Possible production errors can thus be compensated for during the production process, for example, by an increased process time for the optic fiber. Optical sensor bands can be produced by the above method for application in the bumpers of motor vehicles as recognition sensors for the impact of a pedestrian. Other applications in which the bending of a sensor band is to be determined by optical means are also envisaged.

Abstract: In a method and a device for measuring a torsion of a body with the aid of flexion sensors (B1, B2), a respective flexion effected by the torsion is detected at the flexion sensors by a first flexion signal (T1) of the first flexion sensor (B1) and a second flexion signal (T2) of the second flexion sensor (B2), and a flexion signal (CT) characteristic of the torsion is obtained by subtracting the first flexion signal from the second flexion signal or by adding the first flexion signal and the second flexion signal.

Abstract: The invention relates to a method for creating a fibre strip (12) composed of individual fibres (11). some sections of the latter (11) being subjected to a surface treatment, far example by moms of a laser (13). According to the invention, the individual fibres (11) are conducted in the fibre strip (12) without torsion, at least between the treatment process step and the fitting process step to prevent distortion. This ensures that the angular position of the surface-treated sections in the fibre strip (12) can be advantageously predicted and that the optical behaviour of the fibre strip, which is dependent on the flexure, permits conclusions to be drawn about the degree of bonding in the fibre strip. The fibre strip can be used, for example, as a sensor strip, which can be utilised in the bumper of a motor vehicle to identify the impact of pedestrians.

Abstract: The invention relates to a system for detecting function parameters for the characterization of motion sequences at the human body, comprising: a bending sensor with at least one strain gauge for detecting bending parameters, wherein said at least one strain gauge changes its impedance during an extension or compression, and sensor electronics for reading out and processing the bending parameters detected by said at least one strain gauge; and a fixing element for fixing the bending sensor on the skin of the human body, wherein said fixing element is adapted to accommodate said bending sensor such that it is fixed only at one point of said fixing element and follows motions of that part of the human body on which said fixing element is fixed without following possible extensions of the skin of the human body.

Abstract: A sensor application (11) has modules consisting of a carrier strip (13) and a sensor strip (12). The sensor strip (12) is fixed to the carrier strip (13) which, in turn, is fixed, for example, to the back of a human proband. In this way, the spinal curvature can be determined, the carrier strip (13) and the sensor strip (12) being elastically embodied for this purpose. The carrier strip (13) has a data memory (22), for example an RFID label on which relevant information is stored. The data can be evaluated by an evaluation device (14), and the sensor strip (12) is only released when the carrier strip is suitable for the sensor strip used. In this way, defective functions and measuring errors are advantageously avoided.

Abstract: An untreated fiber section in an optical sensor fiber has a zone which is framed by surface-treated fiber sections, thus making it possible to determine, by metrology, a mixture of light modes in the untreated fiber section that depends on bending. This advantageously makes it possible to measure the bending in the optical sensor fiber in a very accurate manner. The optical sensor fiber may be used in sensor having a laser diode and a photodiode.

Abstract: An optical fiber sensor has a sensor band of optical sensor fibers. The band is connected on both ends to a transmitter unit and a receiver unit, the transmitter unit feeding optical signals into the optical fibers, the signals being optically evaluated with regard to the intensity thereof by the receiver unit. Parallel electrical conductors are located in the sensor band and can, for example, be designed as ribbon cables. The electrical conductors allow an additional electrical connection of the transmitter unit and the receiver unit, so that external cables advantageously need only be connected to one of the two units. The difficulty of connection is thereby reduced, and the wearing comfort is increased for the application of the fiber sensor, for example, as a back sensor.

Abstract: A device (V) for fixing at least one fibrous strip (FB) to a body part (K), wherein the fibrous strip comprises at least one fibre (F) embodied as a fibre-optic bending sensor, has at least one fixing unit (BE) which respectively has (a) a fixing part (BM) for applying part of the fibrous strip to the body part, and (b) at least one fixing loop (BS) for guiding the fibrous strip along an axis of a three-dimensional space. The fixing loop can be fixed to the body part.

Abstract: A rotary transmitter for transmitting optical signals between two components is described. In accordance with the invention, provision is made for a fiber optic cable, optionally also a second fiber optic cable to be used to transmit the signals, the latter being suited, due to their surface treatment, to coupling signals of send elements and forwarding them to an interface in order to be registered there by a receive element. The fiber optic cables are laid such that they describe a circle upon which the transmission elements rotate about an axis of rotation. As a result, a complete data transmission is possible by way of the waveguide. The components (send elements, receive elements and the optical fiber cables) can be fastened to an annular printed circuit board by SMT.
