against liquids and gasses. In 1971, Bendix introduced the world's first true computerized ABS (anti-lock) system on Chrysler's 1971 Imperial. Production continued for several years. Under its present ownership by Honeywell, Bendix continues to manufacture automotive brakes and industrial brakes for a wide variety of industries. In 2014, Honeywell sold the Bendix trademark for automotive brakes in the US, to MAT Holdings. Many Bendix automotive, truck and industrial brakes sold in the United States used asbestos as late as 1987. Bendix's current parent, Honeywell, continues to deal with numerous lawsuits brought as a result of asbestos-containing Bendix brand brakes. In February 2020, Bendix announced that it would be moving its headquarters from Elyria, Ohio to Avon, with an expected opening date for its new facility of November 2021. Mass spectrometer A collaboration between Fred McLafferty and Roland Gohlke and William C. Wiley and Daniel B. Harrington of Bendix Aviation in the 1950s led to the combination of gas chromatography and mass spectrometry, and the development of Gas chromatography–mass spectrometry instrumentation. Beginning in the 1960s, Bendix produced scientific instruments such as the Bendix MA-2 Time-of-Flight Mass Spectrometer. Radiological Dosimetry Bendix also manufactured Radiological Dosimeters for Civil Defense during the cold war, they also made a Family Radiation measurement kit for home use, which included a CDV-746 dosimeter and a CDV-736 Rate meter, which looked like a dosimeter. Dosimeters manufactured by Bendix for the Office of Civil Defense included: CDV-138; CDV-730; CDV-736-Ratemeter; CDV-740; CDV-742, the version most commonly used by Civil Defense; and CDV-746. The Dosimeters measured in Roentgens an hour, which is the standard measurement for ionising radiation. 'Dashaveyor' Automated Guideway Transit In the late 1960s Bendix purchased the rights to the Dashaveyor system – developed for mining and goods movements – in order to use it as the basis for an automated guideway transit (AGT) system, during the heyday of urban transport research in the late 1960s. Often referred to as the Bendix-Dashaveyor in this form, the system used the basic design of the cargo system, but with a larger passenger body running on rubber wheels. Although it was demonstrated at Transpo '72, along with three competitors, only one Dashaveyor system was installed, the long Toronto Zoo Domain Ride which operated from 1976 until its closure in 1994 following an accident due to poor maintenance. Bendix ceased marketing the system by 1975 after it failed to attract interest. Avionics, military
