Abstract: L'invention se rapporte à un survolteur-dévolteur statique (18) assurant une correction optimisé du facteur de puissance en cas d'effets de résonance en ligne et d'harmoniques de grande amplitude. Un signal de commande de grille est appliqué aux dispositifs à semi-conducteurs (21) du cycle fondamental pour éviter d'endommager les dispositifs à semi-conducteurs (21) et les condensateurs (20) du survolteur-dévolteur (18) à la suite des effets de résonance en ligne ou des harmoniques de grande amplitude. Ce signal de commande de grille relativement court, en présence d'harmoniques de grande amplitude, provoquera la retombée prématurée des composants électroniques transistorisés. En conséquence, les condensateurs (20) du survolteur-dévolteur (18) assurent une compensation incomplète de l'énergie réactive. Une rétroaction du circuit à condensateur de polarité (31) permet de déterminer l'état commuté du condensateur à un instant spécifique dans chaque cycle. Un survolteur-dévolteur (24), sensible à la contre-réaction, met en oeuvre un dispositif de commande pour prendre en compte la compensation incomplète de l'énergie réactive.

Abstract: A scheme for carrying out modular calculations which is capable of carrying out modular calculations using redundant binary calculation even when a number of bits of the mantissa (dividend) is larger than a number of bits of the modulus (divisor). In this scheme, the divisor c in the divisor register is left shifted by (i-j) digits when a number of digits j of the divisor c is less than a number of digits i that can be stored in the divisor register, and the modular reduction a mod c is calculated up to (i-j)-th decimal place using the dividend a and the left shifted divisor c. Alternatively, the divisor c given in h-ary notation in the divisor register is left shifted by (i-j) digits when a number of digits j of the divisor c is less than a number of digits i that can be stored in the divisor register, while the dividend a given in h-ary notation in the dividend register is left shifted by (k-~) digits when a number of digits ~ of the dividend a is less than a number of digits k that can be stored in the dividend register, where k ~ i. Then, the modular reduction a mod c is calculated up to a digit of [(k-~)-(i-j)]-th power of h using the left shifted dividend a and the left shifted divisor c to obtain a remainder, and this remainder is right shifted by (k-~) digits.

Abstract: A modulation/demodulation system and method comprising transmitting structure having first and second PN generators which produce distinct, synchronized, first and second PN sequences. A tapped delay line generates a plurality of symbols from the second PN sequence, each symbol corresponding to an offset of the second PN sequence by one or more chips from the epoch of the first PN sequence. A plurality of output taps are associated with the lapped delay line, with each tap corresponding to one of the symbols. A symbol selection device associated with the output taps selects from amongst the symbols based upon one or more message signal bits. The selected symbols and first PN sequence are applied to separate channels of a modulator to modulate a carrier signal. At a destination, first and second local PN generators generate first and second PN sequences which correspond to the first and second PN sequences in the transmitting structure. A tapped delay line connected to the second local PN generator generates a plurality of symbols which correspond to the symbols in the transmitting structure. An analog baseband signal is recovered from the modulated carrier signal and sampled, and each sample is multiplied by the symbols from the tapped delay line. The resulting products are filtered, summed and compared to a predetermined threshold, and the sum which exceeds the threshold is converted to a bit pattern. Consecutive bit patterns are combined to produce a serial data stream which corresponds to the message signal.

Abstract: An improved rinse water additive dispenser for an automatic washer has a substantially rigid body having a resilient portion and an internal volume. The dispenser further includes an opening therein and a valve for sealing the opening closed so that the rinse water additive is maintained within the dispenser until the valve is acted upon by centrifugal force applied to the dispenser during a spin cycle of the automatic washer to unseat the valve. The resilient portion provides for volumetric expansion and contraction of the dispenser when the dispenser is placed in variable temperature water. The volumetric expansion and contraction substantially relieves an air pressure differential between ambient and the internal volume so that the centrifugal force unseats the valve without interference from the pressure differential. The opening may be in the resilient portion or in the substantially rigid body.

Title: Method and assembly for monitoring a predetermined level in a container
Inventor: LOPATIN SERGEJ
IPC: G01F23/22
Filed: 1998-04-16
Granted: 2001-07-10
Abstract: An assembly for monitoring a predetermined level of a material in a container comprises two ultrasonic transducers mounted on the container in line with the level to be monitored, such that an interspace exists between the ultrasonic transducers into which the material enters on attaining the level to be monitored. The one ultrasonic transducer is an emitter transducer which at predetermined points in time for emitting ultrasonic pulses is energized by a frequency which is so low that the ultrasonic pulses are transmitted through the interspace to the detector transducer even when the interspace is filled with air. The other ultrasonic transducer is a detector transducer which converts detected ultrasonic pulses into electrical detection signals. To determine whether or not material is in the interspace between the ultrasonic transducers a check is made as to whether the detector transducer outputs after each point in time of emission a detection signal in a time interval corresponding to the transit time of the ultrasonic pulses from the emitter transducer to the detector transducer in air.

Abstract: A unified messaging system includes a voice gateway server coupled to a n electronics mail system and a private branch exchange (PBX). The voice gatew ay server provides voice messaging services to a set of subscribers. Within the voice gateway server, a trigraph analyzer sequentially examines 3-character combinations within a text message; determines occurrence frequencies for the character combinations; compares the occurrence frequencies with reference occurrence statistics modeled from text samples written in particular languages; and generates a language identifier and a likelihood value for the text message. Based upon the language identifier, a message inquiry unit selects an appropriate text-to-speech engine for converting the text message into computer-generated speech that is played to a subscriber.
