Abstract: The two spring arms of a U-shaped hoop are pre-spread by means of struts which start from the spring arms and with their free ends are supported on one another. The hoop placed on the substrate with its U-contour parallel to a circuit substrate is soldered with the free ends of the spring arms to contact surfaces of the substrate which are in intimate thermal contact with thermally stressed circuit parts (in particular film resistors) of the substrate circuit. By bending the struts beyond the elasticity limit, the spring arms are released and can spring away from the respective contact surface towards each other when the solder softens. As a result the circuit is interrupted by a circuit part which has become too hot. By corresponding thermal allocation of the circuit part to the contact surface of the one or other spring arm, it can be detected immediately which circuit part has been thermally overloaded. <IMAGE>

Abstract: In a computer operating system environment, program units are identified. Applications execute multiple loadable program units. The operating system permits the applications to externally reference to segments not included in the application's executable code through dynamic linking. These external references are application program interface calls to special program dynamic link libraries, DLLs, which contain run-time API function code. External references of subsequent applications referencing the same function are resolved to the same selector and offset. Only one copy of application program interface code is thereby required for a plurality of applications. Each DLL has a dynamic link identifier function, DLIF, as an entry point within the DLL. The DLIF allows programs to be written calling routines which provide selectors for each DLL in the respective program. A program provides display of all DLLs by name with respective selectors. Another program takes a selector reported to the system kernel upon abnormal application termination and returns the DLL identification including the number of the selector within the DLL. An application program interface to the system kernel thereby identifies code selectors for a given DLL file or, alternatively, identifies a DLL file given a code selector.

Abstract: A known optical fiber connector includes an elongated mount which is encompassed by a housing that releasably pinches a free end of an optical fiber against a groove in the surface of the mount, thus connecting that free end either coaxially to a free end of another optical fiber or to an opto-electronic element. That connection is made more secure by a block (12) on which the mount (16) can be precisely lodged. The block is formed with a channel (28) extending substantially parallel to the mount and a slide (25) that is slidable in the channel between advanced and retracted positions. When advanced, a protrusion (31) on the slide causes the housing (22) to be deformed, thus enabling a free end of an optical fiber (21) to be positioned in the groove (18) of the mount. When the slide is retracted, the housing returns to its undeformed state and pinches the optical fiber against the groove. Upon movement of the slide to its retracted position, the protrusion causes a post to grip an intermediate portion of the optical fiber, thus securing the fiber against accidental movement. By forming the block with a series of channels and slides, a number of pairs of optical fibers can be interconnected coaxially.

Abstract: Laser diode transmitters contain control circuits for the preconduction current and the modulation current of the laser diode which are controlled via a monitor diode optically coupled to the laser diode. Disablement of the monitor diode may result in an excessively low optical transmission level being deceptively simulated for the control circuit and the modulation current of the laser diode then being increased to the point where the latter is endangered. According to the invention, an improved laser diode transmitter is described which protects the laser diode against excessively high modulation current and transmits an alarm signal to a monitoring device even if the monitor diode fails completely. <IMAGE>

Abstract: On-board equipment for a mobile telephone system has a function of reporting the degree of busyness of message channels available in a service area. While the equipment is in a stand-by condition with no communication being held thereon, the degree of busyness is determined on the basis of electric field levels of individual message channels or control information sent from a control station. When the electric field levels are used to determine the degree of busyness, the electric fields of a plurality of message channels assigned to the service area are detected. If any of the msssage channels has an electric field level higher than a predetermined level, that message channel is determined to be busy. The rate of use of the message channels is calculated by using the number of assigned message channels and the number of occupied message channels. The calculated rate of use is displayed as information which is indicative of the busyness of the message channels. When the busyness is determined on the basis of control information, a lockout signal sent from the control station and indicative of the fact that no idle message channels are available is detected. The number of lockout signals having appeared within a predetermined period of time is determined and displayed as busyness information.

Abstract: An absorbent mixture, as made from fibers formed into a fibrous web and a polymerizable, cross-linkable material, in a liquid carrier. The material, when polymerized and cross-linked, results in a superabsorbent polymer. The material, in the liquid carrier, is dispersed within the fibrous web, as dispersed inclusions, and is polymerized and cross-linked in situ, within the fibrous web, so as to form a composite web comprising the fibrous web and the superabsorbent polymer, as dispersed particles, at least some of which are bound to fibers from the fibrous web. The composite web is ground, so as to cause some of the superabsorbent polymers to become particulate while fragments of the superabsorbent polymer remain bound to fibers from the fibrous web. Before the composite web is ground, it may be provided with a fibrous layer or fibrous layers in intimate contact therewith, and also compressed.

Abstract: A telephone system and method of operation are disclosed which use a microprocessor control system (10), a speech generator (34) and speech memory (46) to automatically place collect calls without the need of a live operator. The telephone uses the microprocessor control system (10) and a speech record/playback generator (44) to receive a destination number and a recorded name from a user. The telephone uses the speech generator (34) to play audio messages to prompt the user throughout the process. The phone informs a called party of the identity of the user and receives responses from the called party through a DTMF receiver (52). A communication path is established through a telephone line interface (38) if the phone receives a response indicating the called party accepts the charges for the collect call. The microprocessor control system (10) generates a billing record for the call which is stored in a call record memory (11). The billing record can later be retrieved to facilitate billing the call.

Abstract: An NxN passive star coupler (10) can be used to provide a high performance optical data network to interconnect many users at gigabit rates. Ignoring excessive losses, a signal incident on any input port (14,16,...N) is divided equally between all of the output ports (15,17,...N). The average power at all of the input ports N of the star is equal to the average power at all of the output ports N. But, the power per channel at each output port is equal to only 1/N of the applied power. This loss which is due to splitting cannot be recovered by an amplifier at either the input port or the output port of the star coupler unless the amplifier saturation power is greater than the transmitter power. This invention solves the problem of amplifier saturation. Briefly, a discrete optical frequency signal which, when combined in the star coupler produces identical frequency division multiplex spectra at each output port is applied to each input port of the passive star coupler and tunable fiber Fabry-Perot filters (in 13,25) are coupled to the output ports of the star coupler. The optical filters select the various channels. An amplifier (in 13,25) is positioned downstream of each optical filter. By placing the amplifiers after the optical filter, the power level applied to the amplifier is substantially 1/(2 N) of the transmitter power and saturation of the amplifier is minimized as a constraint.
