  • Patent number: 10336322
    Abstract: A miniature autonomous vehicle for operation on the public roads is disclosed. The small size allows efficiency for small payloads, but produces a danger of being overlooked by other vehicles. The size of the vehicle is less than driver operated vehicles and may be restricted to less than 200 pounds. Sensors determine the vehicles speed and the presence of environmental vehicles and use a processor to calculate the need for additional visibility. A visibility structure and support structure with lights or markers is controlled by the processor. The markers are controlled in their operation or position by the processor on the basis of the sensor data. Extending or raising and retracting or lowering the structure affects the air resistance and stability of the vehicle. The structure can be raised when the vehicle stops or is in traffic and lowered at road speeds in light or absent traffic.

  • Patent number: 9911076
    Abstract: A rectification circuit has a first terminal to which an alternating-current voltage is input from an antenna, a second terminal to which a direct-current voltage is input from the antenna, a first rectification element, a second rectification element, and a voltage rectification circuit. The first rectification element is connected between the first terminal and the second terminal, causes a current to flow in a first direction from the first terminal to the second terminal, and cuts off a current in a second direction from the second terminal to the first terminal. The second rectification element is connected between the first terminal and the second terminal, causes a current to flow in the second direction, and cuts off a current in the first direction. The voltage rectification circuit outputs a rectified voltage obtained by rectifying a voltage that is input between the first terminal and the second terminal.

  • Patent number: 9904824
    Abstract: A mm-wave RFID tag interrogation apparatus includes multiple transmitting antennas, and multiple receiving antennas. The transmitting and receiving antennas are spatially distributed and oriented in orthogonal polarization states. A transmitter is coupled to the transmitting antennas, and transmits a corresponding multiple number of separable mm-wave signals. A receiver coupled to the receiving antennas is configured to extract separable components of received mm-wave signals. A processing unit processes the extracted signal components using a synthetic aperture algorithm. An RFID tag, readable by the interrogation apparatus, includes meander-line conductive elements arranged to encode information spatially on a substrate.
