of Silent-Aire. (Silent-Aire was a Canadian firm that specialized in data center cooling systems. The deal was structured as follows: Johnson Controls paid $630 million upfront, and additional payments were made contingent upon reaching certain milestones, with total price capped at $870 million.) In October 2021, it was announced that Johnson Controls had picked Ava Robotics to power its new 'Tyco Security Robot'. This fully autonomous security robot includes sensors, touchscreen and integrates two Tyco Illustra cameras to bring access control, video surveillance and security robotics together. Women's work rights In 1982, Johnson Controls enacted what it called a "fetal protection policy", which denied women the right to work on the battery production line because of the potential harm to a fetus they might conceive. Women were allowed to work on the production line only if they could prove that "... their inability to bear children had been medically documented." In April 1984, the United Automobile Workers sued Johnson Controls on behalf of three employees. These employees were Mary Craig, who had chosen to be sterilized to avoid losing her job, Elsie Nason, a 50-year-old divorcee, who had suffered a loss of compensation when she was transferred from a high paying job that exposed her to lead, and Donald Penney, who had been denied a request for a leave of absence for the purpose of lowering his blood lead levels because he intended to become a father. The case was argued before the Supreme Court of the United States on 10 October 1990 and was decided on 20 March 1991. The Court ruled in favor of the plaintiffs. This was a landmark ruling because it affirmed that "... it is no more appropriate for the courts than it is for individual employers to decide whether a woman's reproductive role is more important to herself and her family than her economic role."
