Title: Radiofrequency gaseous detection device (rf-gdd)
Inventor: DANILATOS GERASIMOS DANIEL
IPC: H01J47/06
Filed: 1998-11-18
Abstract: An alternating electromagnetic field in the radiofrequency range is applied in a gaseous environment (4). Free electrons produced in the gas (4), by an ionising source of radiation (5) or by interaction of a charged particle beam with a specimen, are acted upon by the alternating electromagnetic field and undergo an oscillatory motion resulting in multiple collisions with the gas molecules or atoms. Amplified electron and photon signals are generated in a controlled discharge, proportional to the initial number of free electrons, and are collected by suitable means (6, 7, 8). The alternating field is generated either by electrodes (1, 2) biased with an alternating voltage, or by a coil driven by an AC current, and may be superposed with a static electric field. The detection device may be used with instruments such as electron microscopes, in ion beam technologies, and with instruments used for detection of ionising radiations such as proportional counters.

Title: Systeme de protection collectif transportable
Inventor: BROWN LOUIS
IPC: A47K3/28
Filed: 2000-10-06
Abstract: La présente invention concerne un système de protection collectif transportable modulaire servant à décontaminer et à contenir le personnel dans une zone non toxique. Une zone d'isolement de contamination permet de décontaminer le personnel avant qu'il n'entre dans la zone non toxique. La migration des agents de contamination est empêchée grâce à une purge d'air pur filtré circulant de la zone non toxique à la zone de contrôle de contamination et à l'environnement extérieur. Une unité de soufflage et de filtrage alimente la zone non toxique en air afin d'y maintenir une surpression, garantissant ainsi que toute entrée dans la zone non toxique se fait à travers un flux d'air pur.

Inventor: WILLIAMS L LLOYD
IPC: H04M3/36
Filed: 2003-07-18
Abstract: A method and apparatus for efficiently utilizing resources in a switched telephone network (10) by providing call treatment for calls to specific telephone numbers. The call treatment is provided at a closest available resource (50) to the calling party (56) to avoid routing a connection through the switched telephone network to service termination equipment (58) if resources are not available at the service termination equipment to handle a call. The selected calls are locally parked pending the availability of service termination resources to handle the call. The availability of service resources at the service termination equipment may be determined before a selected call is extended through the network. Advantageously while the call is parked, call treatment discrimination can be performed.

Inventor: ADOUL JEAN-PIERRE
IPC: G10L19/26
Filed: 1990-02-23
Abstract: A method of encoding a speech signal is provided. This method improves the excitation codebook and search procedure of the conventional Code-Excited Linear Prediction (CELP) speech encoders. This code is based on a sparse algebraic code consisting in particular, but not exclusively, of interleaving N single-pulse permutation codes. The search complexity in finding the best codeword is greatly reduced by bringing the search back to the algebraic code domain thereby allowing the sparsity of the algebraic code to speed up the necessary computations. More precisely, the sparsity of the code enable the use of a very fast procedure based on N-embedded computation loops.

Patent CA-2044817-A1 (CA)
Inventor: DENT PAUL W
IPC: H04B1/64
Filed: 1991-06-17
Abstract: The invention relates to a device and a method for processing an analog input signal which varies widely in amplitude, such as speech, for the purpose of reducing the ratio of maximum to minimum amplitude variations of an output signal, after the processing, to the square root of the ratio existing before processing in order better to transmit said signal through a channel of restricted dynamic range in the presence of additive noise.      The device comprises an analog-to-digital converter arranged to change the input signal into a stream of integer numbers. The numbers in the stream represent in some proportional way the instantaneous value of the input signal divided by a reference voltage. This reference voltage is generated by a smoothed amplitude measuring device in proportion to the amplitude of the output signal that is produced, when the number stream is reconverted to an analog signal waveform by means of an digital-to-analog converter working with a constant reference voltage.      The invention also relates to a device and a method for processing a signal of compressed amplitude variation, such as might be produced by the method and device described above, in order to produce a signal of amplitude variation restored to the normal range, being the square of the compressed range.
