Latest Patents

One of Johnson's latest patents is the "Pickup arm control mechanism and electrical circuitry therefore." This invention features a control mechanism that automatically raises, swings, and lowers the pickup arm of a record player based on the positioning of a user's finger. The user's finger bridges pairs of contacts to establish an electrical circuit, generating an input signal to logic circuitry. This circuitry then provides control signals that manage the motion of the arm through suitable transducers.

Another significant patent is the "Phonograph turntable control system." In this system, a touch-activated switch allows the user to control the platter drive motor. When pressed the first time, it sets a digital storage device that sends a platter-motor-start signal. A second press resets the device, terminating the motor operation. The system also includes sensors that monitor various operating conditions, ensuring precise control over the turntable's functions, such as lifting and lowering the tone arm and initiating platter rotation.
