  • Patent number: 11845441
    Abstract: A speed based alarm system to be used in automobiles includes a first touch sensor, a second touch sensor, a processing unit, and a notification alarm. The first touch sensor and the second touch sensor are integrated into a steering wheel body of an automobile to detect the hands of the driver on the steering wheel. The feedback from the first touch sensor and/or the second touch sensor are received at the processing unit along with a vehicle speed, wherein the vehicle speed is retrieved from a vehicle logic board. The processing unit determines if the automobile is at a speed which requires both hands of the driver for better control of the automobile. If the automobile is at a speed that requires both hands of the driver, and only one hand is detected on the steering wheel, the processing unit activates the notification alarm to notify the driver.

  • Patent number: 11841321
    Abstract: A system for biomolecule identification by terahertz sensing, an asymmetric triple split-rectangular (ATSR) metamaterial biosensor, and a method for biomolecule identification by terahertz sensing are presented. The asymmetric triple split-rectangular (ATSR) metamaterial biosensor includes three gap areas which highly confine an electric field. The biosensor includes an E-shaped structure facing an inverted E-shaped structure with gaps between the respective legs. Each leg has a specially designed extension on either side which increases the electric field. A terahertz laser interrogates an analyte upon the metamaterial structure with a plurality of frequencies. The amplitude difference is estimated by an amplitude difference referencing technique. The amplitude difference is matched to a database record to identify the biomolecule analyte.

    Abstract: A solar powered smart window includes a light diffuser configured to convert an incident direct solar radiation to a diffusive light toward interior direction, a light diffuser positioner, a driving mechanism, a solar panel, and a control unit. The control unit moved the light diffuser from a predetermined opened position to a closed position and to hold the light diffuser at the closed position with latch mechanism, when the output power of the solar panel exceeds a threshold for over a duration time. The controller releases the latch mechanism and to cause the light diffuser to return to the predetermined opened position when the output power lowers below threshold for over the duration time. A method includes storing a predetermined condition, monitoring the output power, comparing the output power with the predetermined conditions, making decision whether a positional transition is necessary, and causing the transitional transition or maintaining current position.
