    摘要: A control system enables a user to control an electronic device by moving parts of the face, including the eyes. Optical emitters and optical detectors are used to reflect light from the relevant parts of the user's face. Pattern matching or approximation of a pointing location are used to define the control input to the electronic device based on the user's motions. Visual feedback is optionally provided to the user during the controller's actions. Additional sensor elements are optionally provided to improve performance of the system. Hardware and software elements are combined to provide for the specified control actions.

    摘要: A system provides feedback to a user to guide the user to point a part of the body at a target of interest. An angle sensor senses the angle in which the part of the user's body is pointing, such as the head or the hand. The system computes the angle to a target and compares to the angle in which the part of the user's body is pointing and the feedback indicates to the user how to point more closely to the direction of the target. Additional sensors allow the system to update the angle to the target as the position of the user changes. A walking sensor is disclosed to accurately measure the position of the user.

    摘要: A high intensity surface discharge pulsed light source system includes a dielectric substrate, a first electrode near the dielectric substrate, a second electrode spaced from the first electrode and near the dielectric substrate, with containment for a discharge gas. The system is electrically powered and cooled from a single end. The discharge volume is sealed from the environment for long operational life, and the surface material chosen to allow for high intensity operation. Reflective coatings are employed to increase the light available for practical use. A pulsed electric discharge circuit provides practical operation for long and safe operation.
