  • Publication number: 20190295136
    Abstract: A method and apparatus for releasing evaluation information, in which the feature value corresponding to the object to be evaluated is determined according to the operation information actually occurred by the object to be evaluated, and the comparison value corresponding to the category is determined according to feature values of part or all objects whose category is the same as that of the object to be evaluated. Since the feature value and the comparison value are determined according to the operation information occurred actually without relying on the subjective evaluation of human in the present application, it is more accurate when comparing with the prior art.

  • Patent number: 8738802
    Abstract: A method and member device for forwarding service messages in an Intelligent Resilient Framework (IRF) system and an IRF system. In the method, each member device in the IRF system is allocated to at least two virtual devices, and at least one stack link for each virtual device is configured in order to connect interface boards among different member devices. When it is determined according to a forwarding entry of an interface board in a first member device receiving a service message that the service message is to be transmitted to a second member device, the service message is forwarded via the at least one stack link configured for the virtual device of that interface board.

  • Patent number: 5242707
    Abstract: A system and method are disclosed for producing electro-optic components with transparent, ferroelectric PLZT (perovskite) film characteristics, without lead diffusion. In particular, the fabrication of PLZT-on-sapphire electro-optic components for devices such as spatial light modulators, integrated infrared detectors, and optoelectronic integrated circuits is disclosed, permitting integration of such devices with semiconductor devices having the same substrate, such as silicon-on-sapphire circuits. The system comprises a PLZT film deposition apparatus, a silicon dioxide deposition apparatus, an annealing apparatus, and an optional plasma etching apparatus. During film deposition, material from a PLZT target (source) of suitable (9/65/35) composition is deposited on the substrate and is epitaxially grown on the R-plane (1102) of the substrate, forming a non-ferroelectric, pyrochloric film. The substrate and film are then placed in a silicon dioxide (SiO.sub.2) deposition chamber where SiO.sub.
