  • Patent number: 10999322
    Abstract: The presently-disclosed solution provides an innovative system and method to protect a computer user from a phishing attack. Computer vision is effectively applied to match identifiable key information in suspect content against a database of identifiable key information of legitimate content. In one embodiment, the presently-disclosed solution converts suspect content to a digital image format and searches a database of logos and/or banners to identify a matching logo/banner image. Once the matching logo/banner image is found, the legitimate domain(s) associated with the matching logo/banner image is (are) determined. In addition, the presently-disclosed solution extracts all the URLs (universal resource links) directly from the textual data of the suspect content and further extracts the suspect domain(s) from those URLs. The suspect domain(s) is (are) then compared against the legitimate domain(s) to detect whether the suspect content is phishing content or not.

  • Publication number: 20200302951
    Abstract: A sound-based activity recognition system has the potential to better detect and identify activity in an environment compared to video-only monitoring systems. However, conventional sound recognition systems are typically unable to provide sound recognition using a single device and have limited user control of data and video integration. These shortcomings may be overcome by a sound-based activity recognition system that incorporates computationally inexpensive methods to detect and identify sounds that can be performed on a single electronic device. The activity recognition system may further provide object recognition to enable both sound and object detection. In one example, the activity recognition system may include a microphone and a camera to record audio and video from the environment and a processor to filter background noise, which reduces the amount of data processed; to identify sounds and objects using a model; and to notify a user of the sounds and objects detected.

  • Publication number: 20200278240
    Abstract: The present invention discloses a piezoelectric patch-based real-time and high-precision bolt preload detection method and system. A piezoelectric patch is used as an ultrasonic excitation source and pasted on the head of a bolt, and the high-precision fitting relationship between the ultrasonic change of time-of-flight and the bolt preload is established according to the law of the ultrasonic change of time-of-flight of single echo with the stress so that the real-time detection of the bolt preload is realized by using the mathematical relationship. Compared with the previous method using ultrasonic probes, the present invention eliminates the error caused by the uncertainty of couplant thickness and further improves the measurement precision by using the change of time-of-flight of single echo. Meanwhile, the low-error rate measurement of the bolt preload is realized at a low cost and without affecting the structural performance.
