    摘要： A cryptographic session key is utilized to maintain security of a digital identity. The session key is valid only for a limited period of time. Additional security is provided via a bimodal credential allowing different levels of access to the digital identify. An identity token contains pertinent information associated with the digital identity. The identity token is encrypted utilizing public-key cryptography. An identifier utilized to verify the validity of the digital identity is encrypted with the cryptographic session key. The encrypted identity token and the encrypted identifier are provided to a service for example. The service decrypts the encrypted identity token utilizing public key cryptography, and decrypts, with the cryptographic session key obtained from the identity token, the encrypted identifier. If the identifier is determined to be valid, the transaction proceeds normally. If the identifier is determined to be invalid, the transaction is halted.

    摘要： An apparatus for transporting racks of sealed sample tubes, mixing a sample material contained within the tubes, and aspirating samples from the tubes. The apparatus includes a car which runs along a rail. The car drives racks containing the sample tubes into a mixer channel disposed above and running parallel to the rail. The mixer channel is mounted to rotate about an axis parallel to the rail to mix samples and position the tubes to be aspirated. A push pin mounted adjacent to the mixer channel extends into the mixer channel and urges individual tubes against an aspirator assembly mounted on the opposite side of the mixer channel. An input queue is disposed proximate the input side of the rail and an output queue disposed proximate the output side of rail. The input queue supports the racks and feeds them into position to be driven by the car mechanism into the mixer channel. The output queue receives racks after being aspirated and feeds them aft to make room for subsequent racks driven by the car from the mixer channel. The racks include a lateral front wall, a lateral rear wall and a horizontal bottom wall connecting the front wall to the back wall. The racks also include a plurality of vertical side walls connected to the front wall and the back wall to define a plurality of tube receptacles. The bottom wall includes a plurality of equidistantly spaced apertures, each of which is centrally located within a tube receptacle to provide the push pin access to the tubes. The bottom wall also includes a plurality of ribs extending from the front wall to the back wall to be engaged by the car. Biasing means are disposed within each of the tube receptacles to support sample tubes therein.

    摘要： In a computerized system, a sending computer system and recipient computer system exchange an interchange format message in a resource-efficient manner. For example, a transformation writer at the sending computer system selects and transforms only one or few of a plurality of units of the message at the time. The transformed message units are then streamed to the recipient computer system in accordance with a relevant transformation standard, such as the canonicalization standard in the case of XML messages. A transformation reader at the recipient computer system transforms the messages using a buffer big enough for received message units, and passes the transformed units to a file. Thus, the transformation writer acts as a stream writer to pass a message, and the transformation reader acts as a stream reader at the recipient computer system.
