This invention relates to the field of speech recognition technology, specifically a spoken pronunciation correction and evaluation method. The method includes: constructing an audio time-series sequence containing multiple phonemes based on the standard text spoken by the user; comparing the audio features corresponding to different phonemes in the audio time-series sequence based on the standard pronunciation of each phoneme to locate the pronunciation deviation position corresponding to each phoneme; if the current phoneme has a pronunciation deviation position, performing contextual scene analysis on the pronunciation deviation position by combining the duration, interval, and tone of the preceding and following phonemes to determine the deviation type in the current phoneme's context; identifying the user's abnormal pronunciation patterns; and configuring correction weights for each abnormal pronunciation pattern based on the difference feature values ​​between any two abnormal pronunciation patterns, and determining the correction direction corresponding to each phoneme according to the correction weights of the abnormal pronunciation patterns. This achieves targeted and efficient spoken pronunciation correction.

This utility model discloses a disposable snap-on trouser-style diaper, which has a longitudinal center line, a transverse fold line, a front piece, a back piece, and a crotch area, wherein the crotch area connects the front and back pieces. The trouser-style diaper includes: a lining layer facing the body, an outer cover layer, and an absorbent core, wherein a breathable bottom film layer is disposed between the outer cover layer and the absorbent core. It also includes a fastening system and a self-illuminating indicator, wherein the self-illuminating indicator is located at at least one of the following: fasteners at the earpiece, a front waistband at the front piece, the breathable bottom film layer or the outer cover layer, and their components. This allows for visual cues sufficient for caregivers to operate the diaper in dark environments at low cost and without significant changes to the manufacturing process, which helps to enhance product competitiveness.

A server, a lifesaving system, a method, and a program. The server (10) has a determination unit (315), an acquisition unit (302), and a selection unit (325). A determination unit (315) determines whether or not a life-saving activity is necessary for the employee (EP1). The acquisition unit (302) acquires predetermined information from an employee database (25) including personal information of a plurality of constituent personnel of a predetermined organization. The prescribed information is information relating to the suitability of the lifesaving activity for each of the plurality of constituent persons. When the determination unit (315) determines that the lifesaving activity is necessary, the selection unit (325) selects a lifesaving person instructed to perform the lifesaving activity on the employee (EP1) from among the plurality of constituent persons in accordance with the prescribed information.

The application relates to a dv / dt tolerance test circuit and method for a power device, which comprises a gate large-current driving circuit and a main circuit; the main circuit comprises MOS3, a device to be tested, a driving pulse generator V GS , a capacitor C2, resistors R G and R4, and a high-voltage direct-current voltage source V2; the gate large-current driving circuit is connected with the gate of MOS3, is used for controlling the fast turn-on and turn-off of MOS3, clamping the gate voltage of MOS3 at a safe value, and adjusting the size of dv / dt of the main circuit; at the moment of the turn-on of MOS3, one end of the capacitor C2 is forced to be grounded, so that the voltage across the capacitor C2 is rapidly applied to the device to be tested, and then a large dv / dt pulse voltage is generated.

This invention discloses a method and system for Wi-Fi backscatter covert communication utilizing the FCS (Focus Cross Section) characteristic, belonging to the field of wireless communication. The implementation method of this invention is as follows: the transmitting tag encodes covert information into location information, and based on the location information containing the covert information encoding, generates an intentional error during the backscattering of the Wi-Fi signal. After demodulating the Wi-Fi backscattered signal, the receiving end uses the FCS characteristic to determine the location of the intentional error, and demodulates the covert information according to the covert information encoding, thus realizing Wi-Fi backscatter covert communication using the FCS characteristic. By encoding the covert information into intentional error location information at the transmitting end, the amount of covert information carried in the Wi-Fi data packet containing the covert information is increased, thereby improving the throughput of covert communication. This invention also discloses a system for implementing the aforementioned method for Wi-Fi backscatter covert communication utilizing the FCS characteristic.
