Abstract: A quantitative visual test measures the rate at which an individual is able to complete a defined visual task, either on paper or on a self illuminated screen. The task involves comparing a plurality of similar appearing numbers to determine if they are an exact match within predetermined levels of time. Inability to complete the test within the predetermined level of time indicates the likelihood that the individual will exhibit visual stress and dyslexia. Individuals under such stress are then remediated by the use of adjusted lighting environments sometimes including other visual aids.

Abstract: A thermal-pane window unit having an electro-optical shade of adjustable transmittance is provided for reducing radiative heat transfer, as well as conductive transfer, between the exterior and interior of a building and, additionally, for presenting an attractive shaded window appearance. The invention utilizes a liquid crystal cell of selectable light transmittance in combination with a conventional dual pane heat insulating window. The liquid crystal material is preferably electro-optically responsive to a low voltage AC field.

Abstract: An improved apparatus for taking up textured yarn plugs into a cartridge is provided. The apparatus comprises a spiral-walled cartridge and means for rotating the cartridge about a vertical axis while moving it laterally. In operation, the cartridge is rotated beneath a yarn texturizer as textured yarn in plug form is deposited therein in orderly layers. Even with high-speed texturizers, cartridge speed is low. After the plugs have been deposited, the cartridge may be removed, and the yarn plugs may be pulled out for knitting or weaving.
