    摘要: The present invention discloses a fingerprint template and a fingerprint identification method based on fuzzy feature point information. The fingerprint template contains several pieces of incomplete feature point information, including registration information and comparison information, wherein only coordinate information and attribute information of feature points and a value of a polynomial are recorded. In the polynomial P(Xi)=C0+C1Xi+C2Xi2 . . . CnXin, n is an order of the polynomial, and Xi is a numerical value obtained by quantifying one or multiple pieces of feature point information except the registration information in the feature point information and is a coefficient having a certain preset rule. Corresponding feature point information of a scene fingerprint is substituted into the polynomial to figure out C0-Cn, and whether the C0-Cn meet the preset rule is judged to judge whether the scene fingerprint is matched with a template fingerprint.

    摘要: This disclosure provides methods and servers to transmit data packets via Transmission Control Protocol (TCP) connections. In some aspects, transmitting data packets includes receiving a data packet from a first application on a first server. The data packet is analyzed to determine a destination address associated with a second server. The data packet is transmitted based on the address associated with the second server. In some aspects, transmitting data packets includes receiving a data packet from a second application on a second server. The data packet is analyzed to determine the destination address associated with a first application on the first server. The data packet is transmitted based on the address associated with the first application. In some aspects, transmitting data packets includes a flow control mechanism to control data transmission.

    摘要: A current control system includes a first switch, a second switch, and a controller. The second switch is coupled in parallel with the first switch and operable for providing a feedback signal indicative of a current flowing through the first switch. The feedback signal is determined by a width-to-length ratio of the first switch and a width-to-length ratio of the second switch. In addition, the controller is coupled to the first and second switches and operable for adjusting the current according to the feedback signal.
