  • Publication number: 20020076172
    Abstract: An optical subassembly for aligning an optical fiber with a light emitting device includes a fiber optic stub mounted in a ferrule and a v-groove device coupled to the ferule with a loose end of the fiber optic stub lying in the v-groove device. The other end of the fiber optic stub is polished. According to methods contemplated by the invention, the ferrule is mounted in a ring which is welded to a light emitting subassembly. The unpolished loose end of the fiber optic stub self-aligns with a mating fiber in the v-groove device. According to the presently preferred embodiment, the v-groove device is provided with s-bends which aid in self-alignment between the loose fibers.

  • Publication number: 20020060486
    Abstract: A seat arrangement for sitting furniture such as chairs has a seat member and a support arranged underneath the seat member, wherein the support has an elastic body allowing a tilting movement of the seat member about a pivot point arranged at the central seat member area. The elastic body is arranged at the center of the seat member and has an upper side and an underside. The support has a rigid top plate fixedly connected to the upper side of the elastic body and a rigid bottom plate fixedly connected to the underside of the elastic body. The top plate is correlated with the seat member and the bottom plate is correlated with an underframe of the sitting furniture. The same type of tilting support can also be arranged on a back rest of a chair.

  • Publication number: 20020019224
    Abstract: The invention relates to a method and arrangement for using location data in a cellular network. The cellular network includes a centralized map data bank (454) in which the map data are arranged in accordance with the quadtree hierarchy. The terminal includes a presentation means (23) for displaying map data according to the quadtree hierarchy. Some of the terminal's function keys (29) are arranged so as to function as selection keys for fetching more detailed map screens of the quadtree hierarchy to the display. The map data and possible auxiliary data fetched from the map data bank are saved in the terminal's memory for later use.

  • Patent number: 5534783
    Abstract: A method for determining anomalies in a line which is to be investigated detects a signal reflected from the line when a signal in the form of a pulse is applied to the line. In order to be able to carry out this method particularly quickly and with high accuracy, a weighting function is formed having a time profile that is characteristic of the response of a line which is of the same type as the line to be investigated, when it is acted on in the form of a pulse. The line which is in each case to be investigated has a single pulse applied to it as an application in the form of a pulse, and the detected, reflected signal is weighted with the weighting function in a convolution operation.

  • Patent number: 5481195
    Abstract: A method for finding a fault on an electrical telecommunications transmission line, applies a pulse to one end of the telecommunications transmission line and a reflected signal is detected at the same end. In order to be able to find accurately even faults which occur at long range, line pulse responses (J1, J2, J3) are determined and stored for different line lengths of a line of the same type. When a dirac pulse is applied to the telecommunications transmission line, the correlation coefficient (r.sub.11, r.sub.12, r.sub.13) is in each case calculated from sections of the detected pulse response (JA) and from stored line pulse responses (I1, I2, I3), which in each case correspond to the sections in time. The reflection factor (R(t)) by multiplying the correlation factor (r.sub.J1, r.sub.J2, r.sub.J3) by a computation variable (Vxy.sub.J1) which is formed by the quotient of a value from the respective section of the pulse response (JA) and of the line pulse response (J1, J2, J3).
