Abstract: The invention discloses an ultrasonic dual-wave reliability measurement method for a bolt stress. A first ultrasonic dual-wave transducer is configured to transmit and receive an ultrasonic transverse wave or an ultrasonic longitudinal wave, a second ultrasonic dual-wave transducer is configured to receive the ultrasonic transverse wave or the ultrasonic longitudinal wave, and the transverse wave or longitudinal wave generated by the first ultrasonic dual-wave transducer is propagated in a measured bolt. If a difference between TOF for which the first ultrasonic dual-wave transducer receives the echo signal and double of TOF for which the second ultrasonic dual-wave transducer receives the echo signal in a same mode is not greater than a quarter of one transmission period T, the measured TOF satisfies verification requirements. Reliability of time-of-flight data of the ultrasonic wave can be verified, and various measurement errors can be prevented.

The computing system identifies camera motion in each video frame using an optical flow model. The computing system generates a homography matrix for each video frame based on the fitted playing surface model and camera motion. The computing system calibrates each camera based on the homography matrix generated for each video frame.

Abstract: A device for estimating the temperature of a loudspeaker's voice coil includes a signal generator, a signal adjuster, an adder, and a temperature estimator. The signal generator generates and outputs an amplified signal to a loudspeaker according to a measurement signal and an audio signal, and senses a voltage and a current of the amplified signal to generate and output a sensory output.

The temperature estimator obtains an estimated resistance value of the loudspeaker's voice coil according to the blended signal, and generates a temperature signal according to the estimated resistance value, wherein the temperature signal indicates an estimated temperature value of the loudspeaker's voice coil. Additionally, a method for estimating the temperature of the loudspeaker voice coil is provided.
