Title: Innovations of James N Hollenhorst
Introduction
James N Hollenhorst is an accomplished inventor based in Saratoga, CA (US). He holds a total of 5 patents that showcase his contributions to technology and innovation. His work primarily focuses on advanced input devices and photodiode structures, reflecting his expertise in the field.
Latest Patents
One of Hollenhorst's notable inventions is a hybrid pointing device. This input device features a movable puck and a display screen. The puck is designed to move on a surface with a defined field of motion, which is divided into a pointing region and a function region. The controller determines the puck's position within this field, allowing for a cursor to move within a two-dimensional scene. When the puck is in the function region, the display scene can change, with a deformable barrier preventing accidental changes. Users can overcome this barrier by applying additional force to the puck.
Another significant patent is related to an avalanche photodiode array biasing device and structure. This invention includes an array of individual diode devices, featuring at least one active photodiode and one reference diode. A bias control circuit monitors the reference diode's operation and adjusts the applied bias voltage to optimize performance. This innovation enhances the operational characteristics of the photodiode array, ensuring efficient functionality.
