  • Publication number: 20170353812
    Abstract: A system for rotating sound provides for the ability of the apparent direction of sound sources in a listening environment to remain in consistent orientations in space despite rotations of the microphones used to capture the sound and despite rotations of the head of the listener, even when wearing headphones. Modules are provided in the system to distinguish the sound sources and their apparent directions, as well as to rotate the sound sources in response to detected rotations of the listener's head and/or detected rotations of the microphones.

  • Patent number: 9367127
    Abstract: 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.

  • Publication number: 20040008124
    Abstract: An imaging system includes one or more pairs of transmitter conductors and one or more pairs of receiver conductors. One or more input electrical signals are applied to the transmitter electrical signals and coupled to a body to be imaged. One or more output signals are received by the receiver conductor pairs. The one or more output signals are analyzed to generate an image of the body based on the effect of the body on the one or more applied input electrical signals as evidenced in the received one or more output signals.
