Patent GB-0213985-D0 (GB)
Title: Protection in mixed optical WDM systems
IPC: H04B10/032
Filed: 2000-12-28
Abstract: Devices (13.1, 31.1) communicate with each other on a wavelength channel using wavelength specific signals on a working WDM fiber (21) having a parallel protection WDM fiber (23). An SDH system (13.S, 31.S) uses one channel of the WDM system of the fibers as one of the fibres of the working pair of the SDH system and has a separate fibre (37) constituting that fibre of the protecting fibre pair for the SDH-system. To provide an unambiguous or predictable protection behaviour for the SDH system for the working WDM fibre being cut the RETs (29.1, ..., 29.S) have two modes. In the first mode a RET will be on and always carry traffic when the input power is high enough. In the second mode a RET they will not automatically turn on again after it has firstly lost the input signal and thereupon the input signal has returned. The RET can then be manually restarted or restarted after some suitable delay. Then the sequence of events will always be unambiguously defined. For a fibre break on the working WDM fibre, the RET will loose the input signal, turn off, and will not immediately turn on again. Thereby there will always be enough time for the SDH protection scheme to be carried out. The SDH-system will thus automatically have a working protection path, i.e. the now working, former WDM protection fibre. <IMAGE>

Patent GB-8716896-D0 (GB)
Title: Communications system
IPC: H04B7/26
Filed: 1987-07-17
Abstract: In a cellular radiotelephone system, a geographical area is divided into radio zones, each of which comprises a cell set, and a plurality of transponders which relay signals from portable units to the cell set, and from the cell set to the portable units. The use of transponders reduces the talk-back distance. This, in turn, results in a reduction of the power requirement of the portable units, which can therefore use smaller batteries and smaller transmitter components with a resulting reduction in size and weight. No hand-off takes place as the portable unit moves from transponder to transponder within the radio zone. Thus, the subdivision of the radio zone into transponder areas does not overburden the hand-off supervisory system. The number of channels assigned to a radio zone can be changed to suit conditions. In addition, however, the shapes and sizes of the radio zones can be varied with changes in user dispersion, to reduce the likelihood that all assigned channels in a given radio zone will be in use at the same time. The change in shape and size of a radio zone is carried out by breaking the communication link between a group of transponders and one cell set, and establishing a communication link between the same transponders and a different cell set. Hand-off occurs when a portable unit moves from one radio zone to another. The portable unit generates a hand-off request signal when the magnitude of the downlink voice signal falls below a preestablished level.

Patent HU-0203199-D0 (HU)
IPC: C09K23/56
Filed: 2000-09-25
Abstract: The invention concerns a method for microencapsulation of an active principle by coacervation which consists in controlled desolvation or coacervation of a polymer dissolved in an organic solvent containing said active principle, said coacervation being induced by adding a non-solvent causing the polymer to be deposited at the surface of the active principle, and by hardening the polymer deposit by adding a hardening agent, said hardening being leading to the formation of a continuous film coating the active principle. The invention is characterised in that the solvent is selected among ethyl acetate, N-methylpyrrolidone, methylethylacetone and acetic acid. The non-solvent is advantageously an alcohol comprising two to five carbon atoms and the hardening agent being for instance selected among water, alcohols comprising four carbon atoms and mixtures thereof.
