Granted: 2004-02-17
Abstract: A base station including a transmitting and receiving amplifier for amplifying CDMA signals exchanged with a mobile station; a radio stage connected to the transmitting and receiving amplifier for carrying out D/A conversion of a transmitted signal that undergoes baseband spreading, followed by quadrature modulation, and for carrying out quasi-coherent detection of a received signal, followed by A/D conversion; a baseband signal processor connected with the radio stage for carrying out baseband signal processing of the transmitted signal and the received signal; a transmission interface connected with the baseband signal processor for implementing interface with external channels; and a base station controller for carrying out control such as management of radio channels and establishment and release of the radio channels. The base station communicates with the external channels using ATM cells, and with the mobile stations using the CDMA signals by mapping a plurality of logical channels into a plurality of physical channels. The CDMA signals are spreading using two types of spreading code sequences, that is, a short code and a long code.

Title: Repeater for radio signals
Inventor: HODER MATHIAS
IPC: H04Q7/36
Filed: 1997-12-02
Granted: 2006-01-10
Abstract: A repeater for radio signals is preferably designed for mobile use in digital cellular radio networks. The radio signals received in the down-link and/or up-link of the repeater are demodulated, and the thus obtained digital data flows are then remodulated in conformity with the prevailing norms, amplified and retransmitted. An intelligent control unit monitors the signalling traffic in the radio network and automatically tunes the frequency channels transmitted by the repeater with the channels used in the neighbouring radio cell, thus enabling a hand-over of the radio connection to a new radio cell.

Granted: 2008-11-18
Abstract: A process and a device for the treatment of water, especially for removing therefrom a large variety of pollutants, especially organic, inorganic and biological pollutants through in situ generation of ozone. Ozone is economically produced in situ at a high concentration through the interaction of electrolytically produced oxygen and UV light having a wavelength of 189 nm. The device has a set of anode and cathode for electrolytically producing nascent oxygen which reacts with UV light at a wavelength of 189 nm to produce ozone "in situ " within a vessel where the polluted water is submitted to the combinative action of ozone and other oxidation reactions. The device also has a hydrocyclone or retention tank of removing cationic pollutants such as heavy metals, free radicals as well as undesirable electrolysis by-products such as nascent hydrogen through a secondary outlet. Oxidation by-products are subsequently removed from the exiting water stream by means of decantation, flocculation, coagulation or filtration.

Abstract: Apparatus and a method for providing roaming service to a telecom-munications station which can act as a cellular station or if plugged into a jack connected to a land-line switch, can act like a land-line telephone. When such a Universal Main Station (UMS) is plugged into a jack connected to a land-line switch, the station calls a server system which obtains the directory number corresponding to the jack into which the UMS was plugged. The server notifies a home switch of said UMS to forward calls to that directory number. When the UMS subsequently unplugs from the jack, the UMS registers as a mobile station and the home switch is notified to forward calls to the UMS, acting as a mobile station and identified by a secret directory number, identified in the course of the registration. Advantageously, this arrangement allows a mobile station equipped with an arrangement for detecting the presence of land-line power and arranged to substitute signals received from a jack for radio signals to roam widely, and to receive a choice of cellular service or land-line service wherever the station roams.
