Latest Patents
One of his latest patents is a system for determining the amplitude of a power toothbrush brushhead in the mouth. This power toothbrush includes a handle, a brushhead, and a drive assembly that features a processor for driving the brushhead at a selected frequency and amplitude. A miniature gyroscope and an accelerometer are mounted on the brushhead or on a portion of the drive assembly within the handle. These components detect the rotational velocity and orientation of the brushhead during operation. The information from the gyroscope and accelerometer is provided to the processor to determine the amplitude of brushhead movement. This amplitude information can be relayed to the user or further processed for feedback to control brushhead movement.
Another significant patent is a hang timer for determining the time of flight of an object. This invention relates to systems and methods for detecting, calculating, and displaying the time-of-flight or hang-time of a moving and jumping object, such as a skier or snowboarder. The device includes a static acceleration detection device for measuring the static acceleration of the object over multiple periods of time. It also features a calculating device for determining the approximate time-of-flight during these events and a display device for presenting the information in a readable format.
