Title: Innovations of Charles H Hersom
Introduction
Charles H Hersom is a notable inventor based in Toronto, Canada. He holds three patents that showcase his contributions to the fields of sensor technology and satellite systems. His work has significantly advanced the capabilities of sun and position sensors, as well as satellite attitude determination.
Latest Patents
One of his latest patents is for sun sensors using multi-pinhole overlays. This invention allows for the determination of the angular location of the sun or other objects with respect to the sensor. The sun sensor provides high resolution over a wide field of regard. It comprises a sensor housing, multiple pinholes, a detector, and a method for processing the detected information. Each pinhole has a specific field of view, and the detector receives images from these fields, allowing for precise location determination.
Another significant patent is the satellite attitude sensor using thermal imaging. This invention provides a method for distinguishing the boundary of an object from its background by detecting electromagnetic radiation. The method correlates spatial transitions in intensity of overlaid images on a detector, which is particularly useful for determining the attitude of a satellite with respect to the Earth. The use of a thermal infrared detector allows for sharp contrast between the thermal emissions of the Earth and cold space. This invention offers a simple and effective way to determine satellite orientation, utilizing uncooled microbolometer arrays to enhance efficiency and reduce costs.
