Title: Cordless telephone outlet devive
Inventor: LAURENT MAXIM
IPC: H04M1/72502
Filed: 2003-02-27
Abstract: A cordless telephone outlet device that not only provides the cordless telephone access to a telephone network, but also provides the cordless telephone the proper DC electrical energy for proper operation eliminating the need for an unsightly external DC power supply typically connected to an AC outlet. Further, the device significantly reduces exposure of the telephone line connection between the cordless telephone and the telephone network. The outlet device comprises a body having a communications connector mounted thereon and a base attached to the body. The base contains DC power supply circuitry that is connected to a source of AC  electrical energy. The output of the power supply circuit is connected to a DC line terminated with a DC male plug. The cordless telephone can be directly mounted onto the device allowing the communications connector of the cordless telephone to engage directly with a corresponding communications connector mounted onto the device of the present invention while the device also provides DC power to the cordless telephone via the DC male plug. Alternatively, a relatively short telephone line cable can be used to electrically connect the respective communications connectors with the cordless phone mounted onto the outlet device of the present invention.

Title: Security method making deterministic real time execution of multitask applications of control and command type with error confinement
Inventor: DELCOIGNE JEAN
IPC: G06F9/48
Filed: 2001-11-13
Abstract: The method is implemented with a management system of the time-triggered architecture type in association with a processor of a central processor unit that possesses a privileged execution mode to which access is protected by an instruction of the "call to system layer"  type. The only system layer call that is authorized from an application task under consideration to the system layer consists in reporting a change of node in the control graph of the task in question. When the system layer has verified that the call is legal relative to the execution paths of the control graph as described in the constant tables of the application, all of the operations to be performed on the node in question by the system layer are predetermined by the constant tables of the application associated with the system layer. Prior to real-time execution, pre-ordering of the lists of tasks of an application under consideration is performed in a micro-kernel, which subsequently ensures, when called by the system layer during real-time execution, that task lists are updated in ordered manner depending on the new time characteristics of the tasks, specifically their earliest start times d(i) and their latest finish times f(i) as calculated by the system layer.

Title: Drive for a half-bridge inverter
Inventor: FRANCK FELIX
IPC: H05B41/285
Filed: 2003-06-30
Abstract: The selection of the dead time in the case of a half-bridge inverter influences the efficiency thereof.      The optimal dead time, and thus the optimal switching-on time of a lower half-bridge transistor (T2) is accomplished according to the invention by virtue of the fact that switching on is delayed until the current in a level shift transistor (T3) has dropped below a given threshold. A further aspect of the invention consists in that the delay in switching on the lower half-bridge transistor (T2) is immediately suppressed whenever a charging current flows in a trapezoidal capacitor, and this is accompanied by the rise of the half-bridge output voltage (UHB) after the traversal of a minimum.

Title: A flexible wdm ring network
Inventor: OBERG MAGNUS
IPC: H04B10/275
Filed: 2002-03-11
Abstract: An optical WDM network for use for instance in a larger e.g. meshed network is the hubbed type and comprises parallel fiber ring paths (1b), a hub (3h) and satellite nodes (3A, 3B, 3C) connected in the ring path. Client equipments a re connected to the hub and the satellite nodes. A client equipment connected t o the main node can communicate with a client equipment connected to any of th e satellite nodes, using a number of wavelength channels equal to the number o f client equipments in the satellite nodes. The wavelength channel used for transmission from the hub can e.g. be fixed or selected by a tunable optical transmitter (31). The WDM transmitters (9) in the satellite nodes transmits light signals in a fixed one of the wavelength channels to the fiber ring path. A single band drop filter (35) is arranged in the main node to receive the light signals from the satellite nodes. The band drop filter has a drop range selected to drop selected ones of the wavelength channels used by the WDM transmitters in the satellite nodes. This allows the use of light signal s of wavelength channels outside the drop range of the band drop filter for carrying information in the network. In the network flexible connections are achieved in without using cross-connect elements.

Abstract: A fibre optic cable 1 includes a core of primary coated optical fibres 2 embedded in an inner layer 3 of acrylate material, having sufficient tensile strength when cured to lock at least the outermost fibres 2 in place and still allow the fibres to be easily broken out of the assembly for termination and splicing purposes. The hardness of the acrylate layer 3 is such that at least the outermost fibres 2 of the bundle are restricted from moving axially relative to the inner layer 3. The inner layer 3 is then surrounded by a loose thin jacket 4 formed from a mixture of high density polyethylene having a Shore hardness greater than or equal to 60 and a generally uniformly distributed slip agent, including a polyether modified poly (dimethylsiloxane) material such as polyether modified hydroxy functional poly (dimethylsiloxane) material. The mixture from which the outer layer 4 is formed is compacted by means of heat and pressure. The outer layer 4 may also contain a mineral filler, such as calcium carbonate and/or titanium dioxide, in order to improve the stability of the dimensions of the outer layer 4 as the temperature changes.

Title: Sensor temperature control in a thermal anemometer
Inventor: CASPARI FREDRICK W
IPC: G01F1/698
Filed: 2004-01-13
Abstract: A thermal anemometer that separates sensor heating from sensor temperature measurement through a switched sampling technique. This approach demonstrates several advantages over the more typical circuitry employing a bridge, which simultaneously heats the sensor and senses the ambient and velocity sensor temperature. In a thermal anemometer in accordance with the present invention, sensor temperature is determined by sampled measurement of its resistance. Sensor temperature is controlled by varying the voltage applied to the sensor with an error value determined by the difference between actual sensor resistance and the desired resistance.

Abstract: A protective device for a field apparatus includes first and second lateral plates, each plate having a top end and a bottom end. The first and second lateral plates are opposingly situated to mutually support each other in an A-shaped structure. In this A-shaped structure, the top ends are coupled together by at least one coupling device substantially at the apex of the "A", and the bottom ends are coupled together by a fastening assembly. The bottom fastening assembly acts to restrain the rending of the A-shaped structure by a force generated from debris striking the first or second lateral plate.
