IPC: A61B3/028
Filed: 1997-10-23
Abstract: A visual acuity tester based on a personal computer is provided that is capable of displaying visual acuity test characters at varying sizes on a monitor. The visual acuity tester antialiases the test characters to overcome the effects of staircase distortion. Preferably, the visual acuity tester performs unweighted area sampling antialiasing. The visual acuity tester also centers the test characters relative to the pixel array of the monitor to improve the appearance of the test characters. The test characters can be centered relative to either the center of a pixel or the corner of a pixel (a pixel coordinate). Test characters can also be centered relative to a pixel center in one dimension and a pixel coordinate in the other dimension.

Filed: 1997-12-23
Abstract: La présente invention concerne un procédé de protection des plantes contre les attaques pathogènes par le développement de la résistance synergique à la maladie obtenue par l'application d'un microbicide aux plantes immunomodulées. Ces dernières sont des plantes dans lesquelles la résistance acquise systémique est activée, et sont par conséquent dites plantes à activation de résistance acquise systémique. Les plantes immunomodulées peuvent être obtenues de trois manières différentes: en appliquant aux plantes un inducteur chimique de résistance synergique à la maladie comme le BTH, l'INA, ou le SA; par un programme de culture sélectif fondé sur l'expression constitutive de gènes de résistance acquise systémique et/ou un phénotype résistant à la maladie ou en transformant des plantes avec un ou plusieurs gènes de résistance acquise systémique telle qu'une forme fonctionnelle du gène NIM1. En appliquant simultanément un microbicide à une plante immunomodulée, la résistance à la maladie est fortement augmentée de manière synergique; c'est-à-dire, le niveau de résistance à la maladie est supérieur aux niveaux additifs de résistance à la maladie.

Title: Processing method for localization of acoustic image for audio signals for the left and right ears
Inventor: KOBAYASHI WATARU
IPC: H04S1/00
Filed: 1999-07-29
Abstract: In views of a disadvantage that in a conventional method for localization of sound image in stereo listening, the amount of software is increased and the scale of hardware is enlarged, this invention has been achieved to solve such a problem and intends to provide a processing method for audio signal to be inputted from an appropriate sound source capable of higher precision localization of sound image than the conventional method. When a sound generated from an appropriate sound source SS is processed as an audio signal in the order of inputs on time series, the inputted audio signal is transformed into audio signals for the left and right ears of a person and further each of the audio signals is divided to at least two frequency bands.      Then, the divided audio signal of each band is subjected to a processing for controlling an element for a feeling of the direction of a sound source SS and an element for a feeling of the distance up to that sound source, which are appealed to person's auditory sense and outputting the processed audio signal.

Inventor: GIROUARD BRUNO
IPC: B60J1/04
Filed: 2000-01-17
Abstract: An adjustable windshield assembly for an open-air vehicle like a snowmobile or motorcycle has a flexible windshield of sufficient flexibility and resiliency that it can be repeatedly elastically deformed without substantial degradation of strength, stiffness, appearance or translucence. Adjusting the configuration of the flexible windshield affords the rider varying degrees of frontal protection, ranging from a low-drag racing posture offering minimal protection from wind, rain and snow to a less aerodynamic, upright posture offering maximal protection. The configuration of the flexible windshield is controlled by an adjustment mechanism having a rack connected to the windshield and a pinion connected to the base and meshing with the rack such that a rotation of the pinion with respect to the rack causes the flexible windshield to displace and deform relative to the base.

Inventor: KNELLER MAYNARD W
IPC: F16H7/12
Filed: 2000-02-07
Abstract: A belt or chain drive and tensioning system that eliminates radial thrust, on drive segments, which is caused by belt or chain tension, by means of two rollers, applying force equal to each other, on opposing sides of the drive segment. With the said rollers forcing the belt or chain against the drive segment applying radial force on the drive segment equal to and opposite of the radial force exerted by the belt or chain. While radial farces on the drive segment remain neutral, belt tension and traction increase in direct proportion to the increased torque of the drive segment. The primary belt tension is dictated by the tensioning assembly. The absolute belt tension is dictated by the primary tension and the torque of the drive segment acting on the resistance of the driven segment and the resistance of the of the tensioning assembly. The tensioning assembly, in conjunction with the rollers, is also responsible fax, dampening vibration and shock waves in the system, and isolating vibration and shack waves. originating from the drive segment and driven segment, from each other. The system can be applied to any type of endless drive belt or chain and can be disengage and engaged when operated with a friction type drive belt.
