  • Patent number: 5723060
    Abstract: An antifreeze composition is provided having a polyhydric alcohol, a corrosion inhibitor and a colorant of the formula: ##STR1## wherein m and n are independently selected from 0, 1, 2 or 3; M is cation; A is SO.sub.3 M or SO.sub.2 R.sup.3, where R.sup.3 is alkylene-SO.sub.3 M; R.sup.1 is selected from the group consisting of hydroxy, C.sub.1-8 alkoxy, C.sub.1-8 alkyl, amino, sulfoxy, carboxy and R.sup.2 ; and R.sup.2 is NHR.sup.4, where R.sup.4 is triazine or triazine substituted with aminophenylsulfonate, chloro, dichloro, fluoro, or R.sup.2 is CO.sub.2 M.

  • Patent number: 4740780
    Abstract: A head-up display for use in an automotive or other vehicle having limited space. The optical path from display symbol generator to a collimating lens is folded to fit in a relatively compact housing. Also shown is the use of the automobile windshield as a combiner glass for the display. Corrective lenses, and in particular crossed linear fresnel lenses, are used to correct for the astigmatism introduced by the geometry of the windshield. This provides a combination of optical powers for the display lens and the windshield which has the resultant effect of projecting an image from the image source to the driver's eye. The source is a high light output array of light-emitting diodes. A microprocessor based controller for detecting the status of inputs from the automobile is shown. Data is periodically loaded into a random access memory dedicated to controlling the display.

  • Patent number: 4680786
    Abstract: The subject communication system is an improved cellular mobile telecommunication system which provides business communication features to cellular mobile telecommunication customers.This is accomplished by using a business communication system as the switch element in the mobile telecommunication office. The master-slave relationship between the mobile telecommunication controller and the system processor that is found in the prior art is replaced by a peer-peer relationship. The mobile telecommunication control functions are handled by the mobile telecommunication controller while the call processing/connection control functions are handled by the system processor. Thus, the existing business communication call processing software can be used directly and any new business communication service provided by the business communication system is also available to the cellular mobile telecommunication customer.
