Patent CA-2372142-A1 (CA)
Inventor: VOSKULEN LAMBERTUS ANTHONY MAR
IPC: G10L11/00
Filed: 2000-04-28
Abstract: Method and apparatus for detecting far end speech in a telephone apparatus. A  speaker (14) reproduces far end sound from a far end signal, when received by the telephone apparatus. A microphone (12) generates a near end signal from near end sound, for transmission from the telephone apparatus. A hybrid (24) which passes the near and far end signals from an external two wire link (30) to and from the speaker and microphone, on respective first and second paths (1, 2) of a four wire link (28). Muting of the near end signal is effected when signal derived from the first path (1) of the four wire link (28) is detected as being representative of a condition of existence of far end signal. Signal determined as representing sidetone signal deriving from the near end signal from the speaker (14), and appearing in the signal on the first path (1) of the four wire link (28), pursuant to traverse of part of near the end signal through the hybrid, is subtracted from the signal derived from the first path (1) of the four wire link (28). Existence of the condition of existence of far end signal is then determined on the basis of the result of the subtraction.

Title: A passive bumper system for impact energy absorption by gas liquefaction
Inventor: GUIRGIS SAMEH
IPC: B60R19/20
Filed: 2002-02-18
Abstract: A bumper system for an automotive vehicle includes several piston rods, which are connected to a bumper beam at several joints, from one side, and each is connected to a piston from the other side. Each piston is fitted in a cylindrical bore to retain a certain amount of compressed gas and is movable along a straight line from an extended to a reacted position. Pistons are provided with locking mechanisms that allow them to move in one direction only; from the extended to the retracted positions. A  temperature control system is provided to maintain the gas temperature within a curtain range. The vehicle travels while the pistons are in the extended position. An impact on the bumper beam causes the pistons to move inside the cylindrical bores, increasing the gas pressure up to the critical pressure value and changing the state of the gas to a liquid.

Abstract: Disclosed are compositions that comprise one or more N-acylethanolamine compounds for maintaining the freshness and appearance of cut flowers, flora l products, decorative foliage, fruits, and other plant cuttings. More specifically, the present invention provides methods for treating and storin g cut flowers, Christmas trees, fruits, and other severed plant parts that preserve the appearance, freshness, fragrance and/or aesthetic qualities of the botanical products. Using the disclosed compositions, the shelf life of cut flowers was substantially prolonged, in many cases 2 to 5 times longer than untreated flowers, with the treated flowers or foliage appearing health y and viable, and without wilting, dehydration, leaf drop, or visible signs of  senescence. Likewise, treatment of ornamental coniferous plants with the ant i- senescent compositions delayed deterioration and leaf drop, while extending the overall appearance and quality of the plants and plant cuttings.
