  • Publication number: 20230273050
    Abstract: A method for measuring a distance between connectors of different line cards is described. A first measurement component configured on a first line card sends a measurement signal to a second connector configured on a second line card using a first connector configured on a first line card, and determines a distance between the first connector and the second connector based on the measurement signal. The second connector receives the measurement signal and sends a response result of the measurement signal back to the first measurement component, to enable the first measurement component to determine the distance between the second connector and the first connector. The distance between the first connector and the second connector being determined based on the measurement signal enhances flexibility, universality, and accuracy.

  • Patent number: 10077492
    Abstract: The present invention provides an ultrafine-grained profile of twin-crystal wrought magnesium alloys, preparation process and use of the same. In the process, raw materials of magnesium alloys are firstly smelted and cast, and are subjected to solution treatment at 300˜500° C.; then a preform is pre-deformed, so that a great amount of twin crystal microstructure forms in the magnesium alloys and the grain size of not larger than 100 ?m is achieved; subsequently continuous ECAP process is performed at 200˜350° C., and the die is replaced in according to requirement so as to obtain the desired profile. The ultrafine-grained profile of magnesium alloys prepared in the invention has the grain sizes of from 100 to 450 nm, the tensile strength of 300˜400 MPa, and the elongation of 20˜35%. The length of the profile can be more than 10 m, meeting the needs of continuous production.

  • Patent number: 8917914
    Abstract: The present invention provides a novel system and method for identifying individuals and for face recognition utilizing facial features for face identification. The system and method of the invention comprise creating facial features or face patterns called face pattern words and face pattern bytes for face identification. The invention also provides for pattern recognitions for identification other than face recognition. The invention further provides a means for identifying individuals based on visible and/or thermal images of those individuals by utilizing computer software implemented by instructions on a computer or computer system and a computer readable medium containing instructions on a computer system for face recognition and identification.

  • Publication number: 20100306849
    Abstract: A tangible medium embodying instructions usable by a computer system to protect a plurality of guest virtual machines (VMs), which execute via virtualization software on a common host platform, from malicious code is described. A scan engine is configured to scan data for malicious code and determine a result of the scanning, wherein the result indicates whether malicious code is present in the data. A driver portion is configured for installation in an operating system of a target VM, which is one of the guest VMs. The driver portion intercepts an access request to a file, that originates within the target VM. The driver portion communicates information identifying a location of the data to be scanned by the scan engine without sending a copy of the data to the scan engine. The scan engine executes within the virtualization layer outside a context of the target VM.
