Latest Patents

One of his latest patents is for a "Keyboard with adjustable feedback." This invention includes key mechanisms with keycaps and actuators that provide adjustable feedback in response to user input. The actuators are designed to offer variable tactile force or audible feedback based on the user's interaction. The technology allows for the transduction of a keycap's location or relative position as it is pressed, enabling a signal to be sent to the actuators to provide feedback that corresponds to the keycap's movement. This innovation enhances the feel and sound of keyboards, allowing for electronic adjustments that cater to user preferences.

Another significant patent involves "Items with wire actuators." This invention describes items, such as fabric-based products, that incorporate one or more actuators with conductive strands. A control circuit supplies current to these strands, inducing length changes due to ohmic heating and thermal expansion. This technology can be activated in response to user input from various sensors, making it versatile for different applications.
