Abstract: A versatile photonic radio frequency (RF) oscillator (10) employs a single optical feedback loop, or multiple feedback loops of different delay times and including at least one optical feedback loop, to generate RF signals with ultra-low phase noise, narrow spectral linewidth, and a continuous wide tuning range of high resolution.  Specifically, an electro-optical modulator (12) and a long optical fiber loop are implemented in one dual loop system. In addition, a light beam from a light source (40) can be directly modulated by using a single optical feedback signal, or a plurality of feedback signals from multiple feedback loops, to alter the electrical control signal to the light source. Furthermore, the disclosed system supports both electrical and optical RF outputs (32). External optical injection (28) and electrical injection (30) can be implemented.

Abstract: A process and device are disclosed to determine the activity of enzymes in liquids in a largely automatic manner. The device for carrying out this process has a column (1) with a chromatographic carrier for treating a measurement sample. The carrier is mixed with a substance capable of binding to an enzyme inhibitor present in the measurement sample and that corresponds to at least one enzyme. A measurement sample supply (2) is associated to one end of the column (1). A valve/pump arrangement (7, 11, 14, 15) for filling at least one test tube (5) with a carrier and at least part of the measurement sample is connected downstream of the column (1), in the flow direction of the measurement sample. The carrier is dissociated into cleavage products by the action of the enzyme. The rise in concentration per unit of time of at least one of the cleavage products of the carrier is sensed during an incubation time. As an alternative or supplementary step, the enzyme that corresponds to at least one enzyme inhibitor is extracted by chromatography from a measurement sample to detect enzyme inhibitors in liquids and the thus treated measurement sample is tested for inhibitor concentration and/or activity.

Granted: 2007-07-17
Abstract: The invention provides a method and apparatus for controlling traffic congestion in an intelligent telecommunications network in which subscriber services are provided and which has a plurality of nodes or service switching points (11) and a service control point (13). The service control point (13) includes a central processing unit (15) which monitors the moving average of the traffic profile passing through each mode for particular dialled numbers of the subscriber services.  The central processing unit (15) is programmed to detect when congestion occurs, to determine whether the congestion is caused by a sudden change in the profile for a particular dialled number or by a general overload of traffic at the service control point, and to generate congestion control signals which, in turn, are sent from the service control point (13) to the service switching points (11) where admission controls (12) are used for throttling or limiting the traffic through the service switching points (11).

Abstract: Interactive Program Guide (IPG) data for television is delivered to integrated receiver-decoders (IRDs) (130) in a decoder population via, for example, a satellite network (110,120). The IPG data provides scheduling information for global and local programming services which are carried via the satellite network as well as another network such as a CATV network (150) or a terrestrial broadcast network. Each IRD (130) is assigned to an IPG region using unit addressing. At the IRD (130), IPG data is filtered so that only the global data (400) and the region-specific data (405, 410, 415) for the IRD's IPG region is retained and processed by the IRD. Channel map data is also delivered to the IRDs so that bundles of IRD data can be filtered out using firmware filtering (185) to discard program sources that are not present in the channel map. The IRD data which is retained after filtering is used to provide scheduling information via an on-screen display (190, 195). A preferred source may be designated when there are duplicative channels on the different networks.

Abstract: The invention relates to a method for adjusting the flow velocity of reaction gas and the dispersion air of pulverous solids when feeding reaction gas and finely divided solids to the reaction shaft (6) of a suspension smelting furnace for creating a controlled and adjustable suspension. Reaction gas (8) is fed into the furnace from around a finely divided solid material flow (5), so that said solids are distributed with an orientation towards the reaction gas by means of dispersion air. The flow velocity and discharge direction of the reaction gas to the reaction shaft are adjusted steplessly by means of a specially shaped adjusting member (10) moving vertically in the reaction gas channel (13) and by means of a specially shaped cooling block (12) surrounding the reaction gas channel (13) and located on the arch of the reaction shaft. The velocity of the reaction gas is adjusted to be suitable, irrespective of the desired gas quantity, in the discharge orifice (14) located at the bottom edge of the reaction shaft arch (11), and from said orifice the gas is discharged into the reaction shaft (6) and forms there a suspension with the pulverous material, and the dispersion air needed for dispersing said material is adjusted according to the supply of the pulverous material. The invention also relates to a multiadjustable burner for realizing the method.

Abstract: A technique for synchronizing the timing signals in the base stations of a wireless telecommunications system is disclosed. In accordance with the illustrative embodiment of the present invention, each base station derives the frequency of its timing signal from one periodic signal, but the phase of its timing signal from a second periodic signal. In general, the base station derives its timing signal based on: (1) the frequency of a reference timing signal, and (2) the phase of a feedback signal. The reference timing signal can be obtained from a common timing source or from different timing sources which are designed to have the same frequency. The feedback signal is advantageously the confluence of two feedback loops. In accordance with the first feedback loop, the feedback signal is based on the phase of the base station's own timing signal. In accordance with the second feedback loop, the feedback signal is based on the phase of the timing signals from one or more nearby base stations. Advantageously, the feedback signal is based on the Boolean AND or NAND function of the base station's own timing signal and the timing signals of the nearby base stations.

Abstract: A low-latency, high-bandwidth, hybrid TDM/WDM architecture for connecting processing nodes into a high-performance computing environment designed as a system area network is disclosed. Each node has a receiver for receiving optical communication within a fibre at all wavelength channels supported by the system simultaneously and individually. Each node also has a transmitter for transmitting at at least two wavelengths. One of the wavelengths is a default wavelength for the node. In order to transmit data, a node requests a channel and is provided with a transmit wavelength at which to transmit data. Other nodes receive the data and, when the recipient is the addressee of the data, the data is then forwarded to a computing device connected to the node or in communication therewith. The architecture provides robust communication with high bandwidth.

Title: Chimaeric adenoviruses
Inventor: HAVENGA MENZO
IPC: C12N7/00
Filed: 1999-07-08
Granted: 2010-04-06
Abstract: The present invention provides methods and vector systems for the generation of chimaeric recombinant adenoviruses. These hybrid adenoviruses contain a genome that is derived from different adenovirus serotypes. In particular, novel hybrid adenoviruses are disclosed with improved properties for gene therapy purposes. These properties include:  a decreased sensitivity towards neutralizing antibodies, a modified host range, a change in the titer to which adenovirus can be grown, the ability to escape trapping in the liver upon in vivo systemic delivery, and absence or decreased infection of antigen presenting cells (APC) of the immune system, such as macrophages or dendritic cells. These chimaeric adenoviruses thus represent improved tools for gene therapy and vaccination since they overcome the limitations observed with the currently used serotype subgroup C adenoviruses.
