Inventor: GIDEON SALVA
IPC: A61K36/00
Filed: 1994-12-02
Granted: 1997-10-21
Abstract: A  medicinal  substance  for  increasing  fertility  in mammalian males and for use as an anti-microbial or anti-inflammatory agent by mammals is produced by boiling radish leaves, radish stems or portions thereof in water for a period of time sufficient to produce a tea containing an extract from the   radish  leaves   and  stems   or  portions   thereof.          Alternatively, the radish leaves and stems may be placed in hot water for a period of time sufficient to produce a tea containing the extract.  The resulting tea can be drunk hot or cold and may be stored in a refrigerator for extended periods of time for later use.  Patients taking a daily dosage of this tea have shown greatly improved sperm density and improved motility and morphology after use for several weeks.  Dosages of this tea are also effective in treating prostatitis. The preferred radish plant is the spring radish of the species Raphanus sativus.  The leaves of other radish plants including wild and winter or oriented radishes may also be used.

Title: Produce recognition system
Inventor: BOLLE RUDOLF M
IPC: G06V20/68
Filed: 1995-03-10
Granted: 2002-04-16
Abstract: The present system and apparatus uses image processing to recognize objects within a scene. The system includes an illumination source for illuminating the scene. By controlling the illumination source, an image processing system can take a first digitize image of the scene with the object illuminated a higher level and a second digitized image with the object illuminated at a lower level. Using an algorithm, the object(s) image is segmented from a background image of the scene by a comparison of the two digitized images taken. A processed image (that can be used to characterize features) of the object(s) is then compared to stored reference images. The object is recognized when a match occurs. The system can recognize objects independent of size and number and can be trained to recognize objects that it was not originally programmed to recognize.

Title: Method of treating fine ore
Inventor: TESSMER GERO
IPC: C21B13/10
Filed: 1995-03-15
Granted: 1999-09-21
Abstract: In a process for treating fine ore, the fine ore is dried by aid of a hot drying gas flowing around the ore particles of the fine ore, the drying gas, after having flown around the ore particles, is purified while releasing entrained dust ore particles and the dust ore particles are collected and admixed to the dried fine ore. In order to avoid process disturbances in the further processing of fine ore due to excessive portions of dust ore particles present within the fine ore, ~ drying is effected in the whirl-bed method under simultaneous wind-screening of the fine ore, wherein ~ the drying gas is passed through the fine ore under formation of a whirl bed and ~ the speed of the drying gas is fixed at a rate at which entraining of dust ore particles having dimensions below a predetermined dimension is effected, and ~ that the dust ore particles entrained by the drying gas are separated, collected and admixed to the dried fine ore in dosed amounts.

Abstract: A spectral subtraction noise suppression method in a frame based digital communication system is described. Each frame includes a predetermined number N of audio samples, thereby giving each frame N degrees of freedom. The method is performed by a spectral subtraction (150) function ~(.omega.) which is based on an estimate (140) ~v(.omega.) of the power spectral density of background noise of non-speech frames and an estimate (130) ~x(.omega.) of the power spectral density of speech frames. Each speech frame is approximated (120) by a parametric model that reduces the number of degrees of freedom to less than N. The estimate ~x(.omega.) of the power spectral density of each speech frame is estimated (130) from the approximative parametric model.

Abstract: In accordance with the present invention, an apparatus initiates a transaction and includes an acoustic data receiver, and microphone for receiving an audio signal having encoded data that is non-discernable by a listener and is transmitted as part of the audio signal. The microphone converts the sound waves into an electrical signal. A processor receives the electrical signal and retrieves transaction data that is part of the encoded data. A filter is associated with the microphone and removes a substantial portion of a human voice signal that may have been received within the microphone. Once thetransaction data is retrieved, a telephone call can be originated and at least a portion of the transaction data can be transferred to a desired destination for initiating a transaction.
