摘要： An intravascular guidewire with integrated imaging and pressure measurement capabilities is disclosed. The guidewire can comprise an integrated CMUT-on-CMOS ultrasound transducer array to provide 3D imaging of vasculature and other tissue. The guidewire can also comprise a conventional FFR pressure sensor or Doppler flow sensor. Due to the low power consumption of the chip, power can be provided via a single pair of wire pair proximate the core wire of the guidewire to provide power and ground to the chip. The system can also include a power wire, a ground wire, and a data wire, the data wire using similar data transmission techniques. Data from the sensor array can be transmitted over the power wire using, for example, RF or impedance modulation. Data can also be transmitted through the body using an ultra wideband wireless transmitter and flexible patch antenna on the skin.

摘要： A real-time wireless system for recording natural tongue movements in the 3D oral space. By attaching a small magnetic tracer to the tongue, either temporarily or semi-permanently, and placing an array of magnetic sensors around the mouth, the tracer can be localized with sub-millimeter precision. The system can also combine the tracer localization with acoustic, video, and flow data via additional sensors to form a comprehensive audiovisual biofeedback mechanism for diagnosing speech impairments and improving speech therapy. Additionally, the system can record tongue trajectories and create an indexed library of such traces. The indexed library can be used as a tongue tracking silent speech interface. The library can synthesize words, phrases, or execute commands tied to the individual patterns of magnetic field variations or tongue trajectories.

摘要： A homecage system for facilitating an experiment using an animal includes a cage unit configured to hold the animal therein. A misalignment insensitive transmitting resonant wireless power transfer unit encompasses the cage unit. The transmitting resonant wireless power transfer unit is configured to be driven by an external power signal so as to generate a radio frequency wireless power transfer signal. A headstage unit is configured to be physically coupled to the animal and is responsive to the wireless power transfer signal. The headstage unit transmits data wirelessly from a sensor associated with the animal. A control unit is in data communication with the headstage unit and controls the external power signal. A remote unit is in data communication with the control unit. The remote unit transmits control information thereto and that communicates data via a local area network.
