Abstract: In accordance with one embodiment of the present invention, in a wireless telecommunications system, an automatic gain control loop for a base station, comprises a demodulator having at least one output terminal. The demodulator is adapted to demodulate signals received by the base station so as to provide a plurality of phase signals via its output terminals. These phase signals correspond to the phase of the signals received by the base station. A plurality of variable-gain amplifiers are adapted to receive one of the phase signals and to change the amplitude of said phase signals. A plurality of signal processing units are adapted so as to receive signals provided by the variable amplifiers, and each of the signal processing units is further adapted to generate a feedback control signal so as to control the gain of each one of the variable-gain amplifiers. In accordance with another embodiment of the invention, a method for controlling the gain of signals received by a base station in a cellular communication system comprises the steps of demodulating the signals so as to generate phase signals corresponding to the received signals, variably controlling the magnitude of each one of the phase signals based on a feedback control signal, and processing the phase signals so as to generate the feedback control signal.

Abstract: The assembly to treat the surface of a moving polymer material, through the electrical discharge of a barrier dielectric in a controlled gas atmosphere, has a data processing unit (10) to take data on the speed of material movement with outputs to send command signals to the control (14) for the gas feed (7) and the electrical supply (8) control (15). They determine the vol. of gas feed (7) and/or level of power supply (8), as a function of the speed of material (3) travel through the assembly (2), to match the processing action to the movement speed. Also claimed is an operation where the speed of substrate travel is measured through the assembly. The control system sets the vol. of gas delivered (7) and/or the power level of the electrical supply (8) according to the measured substrate speed. Preferably The data processing unit (10) outputs are linked to the controls (18,19) for gas extraction (9), to set the extraction rate in relation to the speed of substrate (3) travel. The gas extraction system has a main exhaust (16) at the entry into the assembly (2) and a second exhaust (17) is at the assembly outlet. The data processing unit (10) is linked to the controls (18, 19) for both exhausts. The data processing unit (10) can simulate and/or use a model for the operation of the assembly (2) to set the parameters for the surface treatment of the substrate (3) passing through, for a given effect at the outlet. The unit (10) is linked to a remote control unit by data links (20). The unit (10) has at least one interface (21, 22) for a manual input.

Filed: 1996-06-06
Granted: 2009-08-18
Abstract: Novel antiviral combinations for the treatment or prevention of viral infections, in particular, HIV, are disclosed. This new antiviral therapy employs either DP-178 or DP-107, viral fusion inhibitors, in combination with at least one other antiviral therapeutic agent. The combinations of the invention are better than single therapies alone, and in certain cases are synergistic. The use of DP-178 or DP-107 is an ideal therapy to combine with another antiviral, given both the novel mechanism which this therapeutic blocks HIV transmission and the non-toxicity of the therapeutic.

Abstract: A mechanism is disclosed for effecting the relative angular adjustment of a pair of coupled members. A rotor is mounted on an axle that is mounted on one member, the rotor having a planar face on one side that has an arcuate groove formed therein such that the radial distance between the groove and the axle varies in a gradual manner with variation in angle about the axle. A pin or the like protuberance is mounted on the other member of the pair so as to enter and be slidingly engaged by the groove. The arrangement is such that rotation of the rotor causes relative angular movement of the members, but pressure between the members will not cause the rotor to turn. The application of this mechanism to the adjustment of keyboard platforms and monitor supports is disclosed.
