    摘要: A locking device includes a housing, a first linking member, a second linking member, a push-pull member, and a stopper. The push-pull member defines a first sliding groove. A first end portion of the first linking member is slidably received in the first sliding groove, and a second end portion of the first linking member is rotationally fixed on the housing. The housing defines a second sliding groove. The stopper is slidably received in the second sliding groove. A second end portion of the second linking member is rotationally mounted on the first linking member. The first end portion of the first linking member is driven by the push-pull member to move along the first sliding groove, which drives the second linking member to rotate, which drives the stopper to move along the second sliding groove.

    摘要: A method to prevent a double spend attack in cryptocurrency transactions recorded in a blockchain can be applied in a device. The device acquires transaction information, the information comprising a type of virtual currency and a transaction amount, and acquires currency price according to the virtual currency type. The device further calculates a transaction value according to the currency price and the transaction amount of the virtual currency, calculates a unit attack cost corresponding to a blockchain network of the virtual currency, adjusts a quantity of the records indicating that a transaction is recorded by the blockchain network to make a total attack cost greater than a transaction value of the transaction, and transmits transaction information of the transaction to the blockchain network.

    摘要: A self-applying braking apparatus to prevent wind-blown movement of a mobile device includes a main body, a resisting member, a retaining member, a pushing member, and a mounting member. The braking apparatus is mounted on an application device by the mounting member. The retaining member provides an elastic force to fix the main body on the application device. The resisting member is disposed on the main body and configured to abut the tarmac or ground to prevent the mobile device from moving. The pushing member is disposed on the main body and is configured to push the resisting member to abut the ground when blown by the wind or by turbulence from a passing vehicle in a predetermined direction, when greater than the elastic force. The braking apparatus prevents unwanted wind-blown movement.

    摘要: A functional module includes an electronic component and a fixing assembly. The fixing assembly includes a base, a handle slidably mounted on the base, a rotating shaft mounted on the base, and a latching hook rotationally mounted on the base by the rotating shaft. The electronic component is mounted on the base. The latching hook includes a latching portion protruding out of the base. The handle includes a lifting portion inclined relative to the base and configured to resist against an end of the latching hook opposite the rotating shaft. When the handle is pulled out, the latching hook is driven by the lifting portion to rotate about the rotating shaft, and the latching portion is retracted within the base.

    摘要: A method for analyzing validity of responses to a questionnaire by students identifies each student in classroom images, and analyzes the defined classroom behaviors of each student over a period of time. The classroom behaviors can include learning behaviors and non-learning behaviors. The method determines whether the non-learning behaviors of each student meet (ie. are less than) or exceed (ie. are more than) one or more preset conditions and accordingly screens the questionnaire responses as being valid or not valid. An electronic device and a storage medium for performing the above-described method are also disclosed.

    摘要: A system for detecting HDDs and in-position states of each of them includes an HDD controller, an analysis module, and a BMC chip. The HDD controller is electrically connected to the HDDs for obtaining SGPIO information and outputting testing signals comprising the SGPIO information. The analysis module receives the testing signals and generates in-position state information according to voltage levels of the testing signals. The BMC chip is electrically connected to the analysis module. The BMC chip receives the in-position state information from the analysis module and generates a detection log accordingly.
