  • Publication number: 20220276442
    Abstract: In various examples, a fiber-optic-splice enclosure may be suitable for use in various applications, environments, and use conditions. In at least some embodiments, the fiber-optic-splice enclosure includes an adjustable length, which may permit the fiber-optic-splice enclosure to be customized to fit various lengths of a spliced region. In a further aspect, the fiber-optic-splice enclosure may include a splice retainer to attenuate vibrational and other forces and reduce potential effects of those forces on the splice. Moreover, in some other aspects, the construction of the fiber-optic-splice enclosure may allow for relatively straightforward and efficient assembly. For example, a key and keyway configuration between different components of the fiber-optic-splice enclosure may permit the components to selectively slide relative to one another or be engaged to one another.

  • Patent number: 8361303
    Abstract: The invention relates to the electrolysis of aqueous electrolyte solutions containing GeO2; hydroxide and water with metal alloy electrodes, such as, copper or tin rich alloy electrodes with alloying elements such as Sn, Pb, Zn, Cu etc, to generate Germane (GeH4). Cu-rich alloy electrodes have been demonstrated to increase the GeH4 current efficiency by almost 20% compared to Cu metal electrodes. Germanium deposition has been found to be either absent or minimal by using Cu-rich alloy electrodes. Several different methods for maintaining the cell performance or restoring the cell performance after a reduction in current efficiency over time, have been identified. A titration-based method for the analysis of the electrolyte, to obtain the concentration of GeO2 and the concentration of hydroxide has also been disclosed.

  • Patent number: 6477362
    Abstract: Emergency call handling may, in the near future, require terminal unit location information to be provided to emergency service centers. Exemplary embodiments of the present invention provide techniques which pass the mobile unit's phone number along to an appropriate emergency service centers in addition to location information. This information can be made available to an adjunct monitoring system by either changing the mobile station identity used to package (Layer 2) an access attempt or by commanding a mobile or base station to explicitly transmit the mobile unit's dialable number during an emergency access so that the adjunct system can read and forward this number.

  • Patent number: 6466568
    Abstract: Variances in bandwidth used by a radiocommunication connection are adapted to by changing the type of information being transmitted. For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Bandwidth in the second (or third) time slot can be used to carry information in a fast out-of-band channel (FOC). The FOC may provide information relating to the same connection as the payload or data field in that time slot, e.g., a service type identifier which informs the mobile or base station of the type of information (e.g., voice, video or data) being conveyed in the payload. Alternatively, the FOC information may be associated with a connection or connections which are different from that supported by the payload or data field containing the FOC.

  • Patent number: 6028854

For example, in a TDMA environment, a first downlink time slot associated with a double- or triple-rate connection may have a first format, while a second time slot associated with the same connection may have a second format different from the first format. Additional bits in the second (or third) time slot can be used to carry payload information which is not required to be transmitted at greater than full-rate. Moreover, FACCH information need only be transmitted in the master channel.
