Abstract: L'invention concerne un procédé d'amélioration de la performance visuelle d'une personne impliquant la correction des aberrations monochromatiques d'ordre supérieur ainsi que des aberrations chromatiques. Cette correction entraîne un bénéfice visuel supérieur à celui obtenu par la seule correction des aberrations monochromatiques d'ordre supérieur ou des aberrations chromatiques. Les aberrations monochromatiques d'ordre supérieur sont corrigées par introduction de profils de phase appropriés afin de compenser les aberrations de front d'ondes de l'oeil (107). Cette compensation peut s'effectuer au moyen de lentilles de contact (152), d'IOL, de greffes encastrées et de greffes apposées possédant des formes de surface appropriées, ou par façonnage de la cornée réalisé par l'intermédiaire d'une chirurgie réfractive ou d'autres techniques. Une aberration chromatique peut être corrigée par un filtrage spectral ou par apodisation artificielle. Un filtre d'apodisation permet de transmettre une amplitude non uniforme sur la pupille de l'oeil. Les lentilles de contact ou d'autres dispositifs oculaires permettant de corriger les aberrations monochromatiques d'ordre supérieur peuvent comprendre un filtre d'apodisation approprié pour corriger une aberration chromatique. Un dispositif optique externe permettant de corriger une aberration chromatique peut être utilisé en association avec des lentilles de contact, etc. pour corriger des aberrations monochromatiques d'ordre supérieur. L'invention concerne également un dispositif et un procédé permettant d'améliorer l'imagerie rétinienne.

Title: Method and apparatus to measure flow rate
Inventor: FRASER JAMIE STUART
IPC: G01F1/7084
Filed: 2001-04-24
Abstract: A method and apparatus for measuring the flow rate of a single phase fluid, particularly a gas, through a conduit.  A pulse of tracer fluid is discharged or injected into a first fluid flowing through a conduit, the concentration of the tracer fluid is measured as a function of time at a point downstream from where it is injected and the flow rate of the first fluid is determined based on the concentration measurements. The concentration of tracer fluid is preferably sampled substantially continuously from when the tracer gas first passes the measuring point until substantially all of the tracer fluid has passed the measuring point and the sampled concentrations integrated. The concentration of tracer fluid is preferably determined by measuring the thermal conductivity of the mixture of first fluid and tracer fluid which is dependent upon the concentration of the tracer fluid.

Abstract: A method of assembling an electrical heater support housing comprises the steps of forming an elongated member having a linear series of spaced apart and interconnected leaves where leaves have aligned outer peripheral end portions and aligned inner periphery end portions narrower in width than said outer peripheral end portions, and each of the leaves has opposing tapering side walls tapering from a respective outer peripheral end portion thereof to a respective inner peripheral end portion thereof. The leaves each have notches and tab members. The preferred method comprises stretching two electrical heating coils beside each other and then mounting insulators onto the coils. Next, the elongated member is moved downwardly so that the notches of the leaves pass over the insulators. Next, the tab members are bent about the insulators to mount the insulators and heating coil elements to the elongated member. The elongated member is then folded to bring adjacent leaves into engagement with each other.

IPC: B41M5/025
Filed: 2001-06-19
Abstract: A color image is digitally printed onto an intermediate transfer medium. The image is subsequently transferred from the intermediate transfer medium to a final substrate, which may be a cellulosic textile, such as cotton. Bonding of the color images is provided by the reaction between compounds selected from each of two chemical groups contained in the intermediate transfer medium. The first group comprises compounds with functional groups capable of reacting with active hydrogen, such as isocyanate or epoxy groups. The second group comprises compounds with functional groups containing active hydrogen, or compounds with functional groups containing active hydrogen after a conversion process. The functional groups of one or both reactive chemical groups may be protected either by blocking with internal or external blocking agents or by a physical barrier such as encapsulating agents. The blocking agents are removed by the application of energy, such as heat, during the transfer of the image from the intermediate transfer medium to the final substrate. The intermediate transfer medium may be comprised of additional components which may be combined with either or both of the above two chemical groups, or applied as separate layers. Examples of such components are a thermally expandable material, an exothermic chemical, a release agent, and/or absorbent material. Transferred images so produced have a soft hand, particularly when applied to a textile, and excellent fade and abrasion resistance.

Abstract: A technique for efficient implementation of pilot signals on a reverse link in a wireless communication system. An access channel is defined for the reverse link such that within each frame, or epoch, a portion is dedicated to sending only pilot symbols. Another portion of the frame is reserved for sending mostly data symbols; however, within this second portion of the frame, additional pilot symbols are interleaved among the data symbols. The pilot symbol or preamble portion of the access channel frame allows for efficient acquisition of the access signal at the base station, while providing a timing reference for determining the effects of multipath fading. In particular, a pilot correlation filter provides a phase estimate from the pilot symbols in the preamble portion, which is then used to decode the data symbols in the payload portion. An access acquisition portion of the receiver uses the phase estimates provided by the pilot correlation filter to process the output of a data symbol correlation filter. The additional pilot symbols embedded in the payload portion are used in a dot product operation to further resolve the effects of multipath fading.
