A power source and microphone are mounted within the housing and control switches are operable from the front surface of the housing. A first memory has a plurality of words stored therein. A second memory has a plurality of word definitions stored therein, each associated with a respective word. A speech recognition apparatus is coupled to the microphone and to the first memory and responsive to the electronic signals generated by the microphone for selecting at least one word from the first memory representative of the specific word spoken by the user. A display is provided for displaying the plurality of words and the plurality of word definitions when the user operates a selected control switch. A related word classification can be also selected from a third memory and displayed on the display.
摘要:
Describes an optical article, e.g., an ophthalmic photochromic article, such as a lens, in which the article includes: (1) a transparent substrate, such as a thermoset or thermoplastic plastic substrate, (2) a multiply laminate adjacent to at least one surface of the substrate, the laminate comprising (i) a transparent, thermoplastic polyurethane film, the thermoplastic, polyurethane film providing a desirable light filtering property, e.g., photochromism, and being juxtaposed to the surface of the substrate, the polyurethane being formed from a material comprising polyether-based polyurethane or polycarbonate-based polyurethane, and (ii) a transparent protective film of polymeric material, e.g., polycarbonate film, adjacent to the thermoplastic polyurethane film. Describes also the aforedescribed optical article having an abrasion-resistant coating affixed to the protective film, e.g., an organo-silane abrasion-resistant coating; and an optical article having an antireflective coating adhered to the abrasion-resistant coating.

This disclosure relates to an improved exterior adjustable rearview mirror for motor vehicles, with air flow apertures designed and arranged for the removal of moisture, dust, debris and the like from the viewing surface of a rearview mirror mounted therein.The exterior adjustable rearview mirror attached to the front side window, in a manner known per se, consists of a fixed rigid rearview mirror housing with a rearwardly opening providing visibility to an adjustable rearview mirror therein. An air intake aperture is formed on the forwardly directed wall of the rearview mirror housing structure, with respect to the direction of travel of the motor vehicle. The air intake aperture serves to direct the flow of air through a vertical air compression chamber within the rearview mirror housing structure. Hence, the flow of air travels out through the air exhaust aperture located above the viewing surface of the rearview mirror. The flow of air exiting the air exhaust aperture applies a force on the viewing surface of the rearview mirror in such a manner whereby moisture, dust, debris, and the like is forced in a vertical direction off the viewing surface of the mirror, as the motor vehicle with the attached exterior adjustable rearview mirror travel in a forward direction.In addition, the design of the air compression chamber together with the moisture sump depression and the moisture weep duct will remove airborne moisture which may be captured within the device. This moisture is removed and is not distributed onto the viewing surface of the rearview mirror.
