  • Wearable Nystagmus Detection Devices and Methods for Using the Same
    Publication number: 20230018876
    Abstract: Wearable nystagmus detection devices are provided. The wearable device comprises first and second sensors configured to sense eye movement of the subject, and circuitry operably coupled to the sensors and configured to detect horizontal and vertical eye movements based on signals from the first and second sensors and/or a transmitter configured to transmit signals sensed by the first and second sensors to remote circuitry configured to receive signals transmitted by the transmitter and to detect horizontal and vertical eye movement based on signals from the first and second sensors. Also provided are systems and kits that include the devices, as well as methods for using devices and systems to monitor eye movement of a subject. The devices, systems, methods and kits find use in a variety of different applications.

  • Spatial puncturing apparatus, method, and system
    Patent number: 8160028
    Abstract: Stations in a N×N multiple-input-multiple-output (MIMO) wireless network always puncture the weakest spatial channel. N?1 spatial channels are always used regardless of the channel state.
    Type: Grant

  • Spatial puncturing apparatus, method, and system
    Patent number: 7710925
    Abstract: Stations in an N×N multiple-input-multiple-output (MIMO) wireless network always puncture the weakest spatial channel. A receiving station determines channel state information for N spatial channels and feeds back to the transmitting station channel state information for only N?1 spatial channels. The channel state information may include a beamforming matrix to cause the transmitting station to utilize N?1 spatial channels.
