Latest Patents
One of his latest patents is titled "Method and apparatus for touch detection based on the velocity of an object relative to a sensor panel." This invention involves an apparatus that detects the approach and touch-down of an object relative to a sensor panel. The apparatus includes a digital filter that determines the first derivative of current flow in the sensor panel. A controller is responsible for determining when this first derivative reaches a maximum. In a preferred embodiment, the controller calculates the magnitude of current flow in various corners of the sensor panel. These magnitudes are summed to compute the current flow from which the first derivative is derived. The controller analyzes the current flow to ascertain when an object is approaching, contacting, or withdrawing from the sensor panel. Thresholds are implemented to prevent false detection of approaching objects.
Another notable patent is "Method and apparatus for touch detection based on the current flow." This method determines when an approaching object has made contact with a sensor panel. The process involves using a controller connected to the sensor panel, determining a value for the approaching object based on current flow, and generating a signal when this value reaches its maximum. This innovation enhances the accuracy of touch detection systems.
