  • Publication number: 20240305989
    Abstract: A detecting system for an unauthorized device having a movable locator is disclosed. The movable locator includes a location positioning unit, a signal sniffing unit, a signal collecting unit, and a device positioning unit. The location positioning unit detects a locator position of the movable locator. The signal sniffing unit detects Wi-Fi signal of an unauthorized device and generates a sensing report message. The signal collecting unit adds multiple sensing report messages to a sensing report record collection. The device positioning unit organizes multiple positioning combinations based on the content of the sensing report record collection, generates multiple positioning results respectively based on the multiple positioning combinations, and performs a weighting process to the multiple positioning results to generate a final positioning result of the unauthorized device.

  • Publication number: 20230184619
    Abstract: Provided is an underground pipe leak detection system, including a sensing device, a storage device, and a processing device. The sensing device is used for collecting a voice signal from an underground pipe during a time period. The storage device is used for storing a voice dataset, and storing the voice signal transmitted by the sensing device. The processing device may access the storage device. The processing device is configured to execute the following operations: training a classification model using the voice dataset; extracting features of the voice signal; inputting the features of the voice signal into the classification model that has been trained to determine if there is a leak in the underground pipe.

  • Publication number: 20220202358
    Abstract: An electronic device and a method for detecting apnea are provided. The method includes: transmitting a wireless signal to a human subject, receiving an echo corresponding to the wireless signal, and obtaining channel state information (CSI) from the echo; generating a detection result according to the CSI; outputting the detection result. Here, the detection result indicates whether an apnea event has occurred on the human subject.
