    摘要: A wavelength conversion device includes a photodetector for generating a photocurrent in response to the detection of radiation at a first wavelength. An avalanche multiplier amplifies the signal photocurrent and feeds this to a light emitting element that produces radiation at a second wavelength shorter than the first wavelength and corresponding to the detected radiation at the first wavelength. The components are assembled together in an integrated stacked arrangement either by epitaxial growth or wafer fusion of the individual components. The device is useful as an image intensifier or thermal imaging device.

    摘要: A fast authentication and access control method of authenticating a network access device to a communications network having an access point communicating with a remote authentication (home AAA) server for the network access device. The method includes the step of receiving an access request having an authentication credential from the network access device at the access point. The authentication credential includes a security certificate having a public key for the network access device and an expiration time. The security certificate is signed with a private key for the remote authentication server. The access point locally validates the authentication credential by accessing the public key of the remote authentication server from a local database, and checking the signature and expiration time of the security certificate. If the authentication credential is validated at the access point, the access point grants the network access device conditional access to the network by sending an access granted message to the network access device. The access granted message includes a session key encrypted with a public key for the network access device. The session key is stored in a database associated with the access point. The access point contacts the remote authentication server to check a revocation status of the security certificate for the network access device. If the access point receives a message from the remote authentication server that the authentication credential for the network access device has been revoked, it suspends network access for the network access device.

    摘要: A baseband processing module of a wireless terminal includes a Turbo decoding module. The Turbo decoding module decodes a Turbo code word to produce one or more Media Access Control (MAC) packet(s) carried by the turbo decode word. Each MAC packet includes a MAC packet header and the MAC packet payload, which carries one or more Radio Link Control (RLC) Packet Data Units (PDUs). The Turbo decoding module decodes the MAC packet header to determine boundaries of the PDUs carried in the MAC packet payload. The Turbo decoding module decodes RLC PDU headers and RLC PDU payloads of the RLC PDUs. The Turbo decoding module writes the decoded MAC packet header, the decoded RLC PDU headers, and the decoded RLC PDU payloads to memory in a word-aligned format. The Turbo decoding module may also operate in various other Turbo decoding modes.
