摘要： The invention relates to a one time password inquiry method, including steps of triggering a one time password token, determining whether the trigger is a generation or an inquiry operation, if it is an inquiry operation, inquiring and displaying the latest generated password; otherwise, generating a one time password. Meanwhile, the invention also provides a one time password token with inquiry function, including a trigger module, a determining module, a one time password generating module, a storage module, a display module and an inquiry module. By adding inquiry function, the token meets the need for a user to inquiry a one time password, eliminates the asynchronous problem between the token and a server, and lowers power loss taken by the token.

摘要： A method of determining a failure event of consumable for a plasma torch is provided. The method includes monitoring at least one of an operating current or an operating voltage during a transfer arc mode of the plasma arc torch. The method also includes determining when at least one parameter associated with the operating current or the operating voltage exceeds a tolerance threshold for a time period indicative of the failure event. The method further includes shutting off at least one of the operating current or the operating voltage of the plasma arc torch when the at least one parameter exceeds the tolerance threshold for the time period.

摘要： The present invention relates to a secure transmission method and apparatus, particularly to a security control method for a data transmission process and a software protection apparatus using the same, where data transmitted between a computer running protected software and the software protection apparatus is in a cipher-text form, and thus a plain text does not appear in a communication line during the whole process. Moreover, since a random number is involved for scrambling and the data is encrypted, hence commands sent from the protected software to and those returned from the software protection apparatus change constantly even when the same command is sent from the sending end. In this way, it will be more difficult for a cracker to crack, thus securing the transmission of private confidential data.

摘要： The present invention uses a smart control module with HID descriptors to communicate with the host side in accordance with the standard HID communication protocol, so as to interact with the smart card, which can eliminate the need of installing a private driver from a particular manufacturer when installing its reader/writer. The driver of the HID device can be installed automatically upon installation of the operating system. The users can use the reader/writer easily without carrying a driver around. It is not necessary for the users to deal with upgraded versions of the driver, to consider compatibilities of drivers for different products, to confront usage risks of the operating system due to the driver, or to worry about contamination of the operating system resulted from the installation and uninstallation of the driver.

摘要： A sensor based vehicle flotation device is suitable for floating a vehicle immersed in sufficient water to activate a protected water sensor and, if desired, to confirm through auxiliary sensors whether a hazardous condition is presented. When such a device detects and verifies that the vehicle is becoming immersed in water, one or more expansible chambers, affording sufficient buoyancy to allow the vehicle to float, automatically and rapidly inflate by means of compressed, pumped or pressurized gas. Upon the successful deployment of the expansible chamber, the land vehicle will begin to float, limiting water damage to the vehicle and/or bodily harm to its occupants, and reducing the risk of the vehicle overturning. The expansible chamber will remain inflated until the land vehicle is returned to safety, and the device is detached from the land vehicle.

摘要： The present invention pertains to an assemblage of sealing nail essentially containing a nail, a propeller, and a blocker that is partially extended beyond the propeller. Wherein, the nail would sequentially penetrate the propeller, the blocker, and then a plank. By means of the nail entering the plank, the propeller and the blocker would be simultaneously urged to densely cover up where the nail inserted. Therefore, a preferred sealing efficiency between the nail and the plank is achieved to guarantee a favorable grouting on the plank.
