    摘要： Herein described is a system and method that tracks the face of a person engaged in a videophone conversation. In addition to performing facial tracking, the invention provides stabilization of facial images that are transmitted during the videophone conversation. The face is tracked by employing one or more algorithms that correlate videophone captured facial images against a stored facial image. The face may be better identified by way of employing one or more voice recognition algorithms. The one or more voice recognition algorithms may correlate utterances of the person engaged in a conversation to one or more stored utterances. The identified utterances are subsequently mapped to a stored facial image. In a representative embodiment, the system used for performing facial tracking and image stabilization comprises an image sensor, a lens, an actuator, and a controller/processor.

    摘要： Herein described is a system and method for modifying facial video transmitted from a first videophone to a second videophone during a videophone conversation. A videophone comprises a videophone image processing system (VIPS) that stores one or more preferred images. The one or more preferred images may comprise an image of a person presented in an attractive appearance. The one or more preferred images may comprise one or more avatars. Additionally, the VIPS may be used to incorporate one or more facial features of the person into a preferred image or avatar. Furthermore, a replacement background may be incorporated into the preferred image or avatar. The VIPS transmits a preferred image of a first speaker of a first videophone to a second speaker of a second videophone by capturing an actual image of the first speaker and substituting at least a portion of said actual image with a stored image.

    摘要： Aspects of a method and system for multi-level security initialization and configuration are provided. A security system may comprise a security processor, a host processor, and at least one security component, such as a descrambler. The security processor may enable a security component based on information stored within a non-volatile memory integrated within the security processor. The host processor may enable generation of at least one configuration command communicated to the security processor for configuring the enabled security component. The configuration command may correspond to a security control operational mode for the security component that may indicate, for example, activation or deactivation of the security component. The security processor may authenticate a digital signature in the configuration command. Initialization and configuration may be performed during a system boot sequence of the security system.

    摘要： The present invention provides a sealing ring and a preparation method thereof. The sealing ring, based on percent by weight, includes 80%-85% of aluminum, 10%-15% of titanium, 0.1%-1% of scrap iron, and 4%-4.9% of potassium fluoroaluminate. Moreover, the present invention provides a method for preparing sealing ring, which includes the following steps: Step A: melting the aluminum in a medium-frequency induction furnace, adding the potassium fluoroaluminate to the medium-frequency induction furnace after melting the aluminum, melting and stirring the mixture evenly; Step B: adding titanium scrap or sponge titanium, and scrap iron to the mixture successively, melting and mixing the mixture totally at 800° C. to 1200° C., standing the mixture after stirring evenly; Step C: removing scum on the surface; Step D: casting into a mold to obtain a final sealing ring.

    摘要： Media gateways (MGs), grouped into a hierarchy, are operable to provide a multiparty conferencing among client devices. Gateway resources such as processors, Codecs and network interfaces are aggregated at each MG to establish distributed connection sessions based on resource management metrics such as minimizing total network. The distributed connection sessions are utilized to provide the multiparty conferencing. Each MG may aggregate the gateway resources, which may be determined utilizing a look-up table, from other MGs for sharing among the MGs. Each MG may be activated to provide the media gateway controller (MGC) processing utilizing the shared aggregated gateway resources. A MG may be de-activated from the MGC processing when needed and the associated connection sessions may be subsequently released. Gateway resources are managed at each MG based on the resource management metrics in order to establish distributed connection sessions to support the multiparty conferencing among the client devices.
