    • Techniques, systems and methods for obtaining biometric signatures and identification are described. Broadly stated, embodiments of the present invention utilize specified geometric principles to provide means for accurate biometric identification using projective invariant features of a subregion of the human body. The present invention provides a means for computing biometric signatures and identification that are projective invariant and hence are not impacted by the viewing angle of the subregion of the human body containing the biometric data. This novel invention removes the restriction, often implicit in the previous work, of the imaging or sensing system being in a fixed repeatable (and generally orthogonal) viewing position. This invention can be applied across a wide range of biometrics, although it is most easily applicable to features that are approximately co-planar. A plurality of such projective invariant features can be used to define a biometric signature to either verify an individual's identity, or recognize an individual from a database of already known persons.
    • 描述了用于获取生物特征和识别的技术,系统和方法。 广义地说,本发明的实施例利用指定的几何原理来提供使用人体的子区域的投影不变特征进行精确生物识别的手段。 本发明提供了一种用于计算生物识别签名和识别的装置,其是投影不变量,因此不受包含生物特征数据的人体子区域的视角的影响。 该新颖的发明消除了在先前的工作中通常隐含的成像或感测系统处于固定的可重复(并且大致正交)观看位置的限制。 本发明可以应用于广泛的生物特征,尽管它最容易适用于近似共面的特征。 可以使用多个这样的投影不变特征来定义生物识别签名以验证个人的身份,或者从已知人的数据库中识别个人。

    • A method for ONT processing of Ethernet messages, comprising: A. the ONT receiving an Ethernet message from the UNI, and, if the Ethernet message doesn't contain a VLAN tag, adding the VLAN tag specified in the Native VLAN property of the UNI to the Ethernet message before forwarding it to the GPON protocol processing module, and; otherwise, forwarding the Ethernet message to the GPON protocol processing module; B. the ONT receiving the downstream Ethernet message with the VLAN tag from the GPON protocol processing module and, if the VLAN tag of the Ethernet message is the same as the one specified in the Native VLAN property of the UNI, removing the VLAN tag before forwarding it to the equipment connected to the UNI for the Ethernet message via the UNI; otherwise, directly forwarding the Ethernet message to the equipment connected to the UNI for the Ethernet message.
    • 一种用于以太网消息的ONT处理的方法,包括:A.接收来自UNI的以太网消息的ONT,如果以太网消息中不包含VLAN标签,则添加在UNI的Native VLAN属性中指定的VLAN标签 将以太网消息转发到GPON协议处理模块之前, 否则将以太网消息转发到GPON协议处理模块; B. ONT从GPON协议处理模块接收到带有VLAN Tag的下游以太网消息,如果以太网消息的VLAN Tag与UNI的Native VLAN属性相同,则删除VLAN Tag 通过UNI将其转发到连接到UNI的设备以进行以太网消息; 否则,将以太网消息直接转发到连接到UNI的设备,以进行以太网消息。
