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: 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: 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: Methods and system are disclosed to minimize inefficiencies for local area users to share and access data. A local proxy server operates in conjunction with a central server. Local area users can post or store (“store”) data, e.g., media data, on the local proxy server in order for the data to be accessed locally. The local proxy server can also store the data from the local area users on a central server. Additionally, the local proxy server can copy data being stored on the central server for local access by the local area users. In this manner, local area users can utilize the benefits (e.g., higher bandwidth and faster download speed) of storing and accessing media data to and from a local area source (i.e., the local proxy server).

Abstract: A fibre optic ribbon has several individual optical fibres, provided, for example, for application of the ribbon conductor as flex sensor trip, with surface-treated partial regions in which individual optical fibres can be provided. The individual fibres are arranged in a support strip with a space between, such that a treatment of the individual fibres, which permits a particularly simple execution of the surface treatment. The individual fibres are treated with removal of the support strip in the partial regions and finally the support strip is provided with a sleeve. Additional passive optical fibres can be inserted in the spaces for protection of the individual fibres during the surface treatment which give additional protection to the individual fibres.

Abstract: Methods and system are disclosed for archiving and forwarding multimedia data. A server can receive multimedia data for a project from any number of users. The server can archive or store the multimedia data in a database for later access. The server can distribute the received multimedia data to users associated with the project. The server can also distribute the multimedia data in the database to individual users associated with the project at different instances in time.

Abstract: A photodiode configuration having at least two photodiodes is described. Accordingly, the photodiodes are formed in a symmetrical configuration on a common carrier, and electrical contacts are situated in a region between the photodiodes. It is therefore possible, in particular, to use monitor diode configurations of identical construction at the two sides of a laser diode array. Accordingly, a laser diode configuration having a correspondingly configuration having a photodiode configuration is further disclosed. Finally, a method for connecting a photodiode configuration to a submount is specified.

Abstract: Methods and system are disclosed allowing media data to be stored on a secondary storage system accessible for local area users. Such users can thus post or store media data (“posted media data”) on a central server and on the secondary storage system. By such a process, posted media data on the central server is in effect “mirrored” on the secondary storage system. As a result, collaborating local area users can utilize the benefits (e.g., higher bandwidth and faster download speed) of accessing posted media data from a local area source (i.e., the secondary storage system). Furthermore, in order to avoid downloading incomplete posted media data, a completion signal or pending signal can be used to indicate if the posted media data has been completely stored or is in the process of being stored on the secondary storage system.
