Title: Mark R Barton: Innovator in Sound and Security Technologies
Introduction
Mark R Barton is a notable inventor based in Los Angeles, CA. He has made significant contributions to the fields of sound-activated devices and security systems. With a total of 2 patents, his innovative designs showcase his expertise and creativity.
Latest Patents
One of Barton's latest patents is the "Sound Activated Liquid Display Device." This invention features a transparent container that holds two immiscible liquids of different densities, colors, and viscosities. A pump with a magnetic coupling injects the denser liquid into the less dense liquid in response to changes in sound volume or frequency, creating a geyser display that reacts to music or voice. The device includes sophisticated pump control circuitry, which consists of a microphone, an amplifier, a filter, an amplitude detector, a long-time averager, and a comparator to ensure precise operation.
Another significant patent is the "Touch Bar Release Locking System." This system includes a hollow metal channel affixed to a door at two points using insulating spacer blocks. A capacitive sensor within the channel detects additional capacitance when a person touches it, even through gloves or clothing. Upon detection, a relay energizes, releasing an electric lock that secures the door. In case of sensor failure, an electromechanical push button allows for egress, ensuring safety and accessibility.
