Latest Patents

One of Penrod's latest patents is an electrical lighting controller designed to reduce energy consumption in high-intensity discharge (HID) lamps and fluorescent lamps. This invention optimizes the output of the controller to the lamps, allowing for substantial energy savings while providing a high degree of lighting. The controller utilizes a variable autotransformer, which is managed by an amplifier comparator circuit, ensuring that the lights operate under optimal conditions. Additionally, a timing circuit allows for a high voltage to ignite the HID lights before transitioning to a lower set point to maintain illumination. In the event of a load change, a wattmeter output feeds back to a power change detector, adjusting the voltage to accommodate additional lights without extinguishing existing ones.

Another significant patent is the power contactor and control circuit, which manages the application of power to various loads, such as motors or heaters. This system includes a power relay with arc suppression means and a steering relay to control the direction of current. The control circuit ensures that the steering relay contacts remain stable while power is applied, preventing short circuits and enhancing safety. The arc suppression means utilizes solid-state devices, such as triacs, to manage the current effectively.
