Black History All Year 2020 . . The patent for the invention was filed in 1966, and it later influenced modern home security systems that are still used today. Brown’s invention was inspired by the security risk that her home faced in the neighborhood where she lived. Marie Brown worked as a nurse and her husband, Albert Brown, worked as an electronics technician. Their work hours were not the standard nine-to-five, and the crime rate in their Queens, New York City neighborhood was very high. Even when the police were contacted in the event of an emergency, the response time tended to be slow. As a result, Brown looked for ways to increase her level of personal security. She needed to create a system that would allow her to know who was at her home and contact relevant authorities as quickly as possible. . . Brown’s security system was the basis for the two-way communication and surveillance features of modern security. Her original invention was comprised of peepholes, a camera, monitors, and a two-way microphone. The final element was an alarm button that could be pressed to contact the police immediately. Marie and Albert Brown filed for a patent on August 1, 1966, under the title, “Home Security System Utilizing Television Surveillance.” Their application was approved on December 2, 1969. Brown’s invention gained her well-deserved recognition, including an award from the National Scientists Committee (no year for the award can be identified) and an interview with The New York Times on December 6, 1969. . . In 1980, she received a patent for her illusion transmitter, which uses a concave mirror on the transmitting end as well as on the receiving end to produce optical illusion images. NASA uses the technology today, and scientists are currently working on ways to incorporate it into tools for surgeons to look inside the human body, and possibly for television sets and video screens one day. . . #securityguard #securitycameras #adt #adtsecurity #queens #queensny #patent #patent #securitysystem #homesecuritysystem #marievanbrittanbrown #blackinventor #blackinventors #inspiration #livevicariously (at Queens, New York) https://www.instagram.com/p/B9bu59XAi2h/?igshid=quo9orfh2czr
