摘要： A method of retrieving security information in a media access control (MAC) header by a wireless station may include receiving a data unit, such as a protocol data unit (PDU), from a remote wireless station. The PDU may include the MAC header. The method may also include reading two encryption key sequence (EKS) bits in the MAC header that denote both whether the data unit is encrypted and a position in an encryption key sequence for the data unit.

摘要： Embodiments of methods, systems, and storage medium associated with providing access to encrypted data for authorized users are disclosed herein. In one instance, the method may include obtaining a derived value for an authenticated user based on user personalization data of the authenticated user, and generating a user-specific encryption key based on the derived value. The derived value may have entropy in excess of a predetermined level. The user-specific encryption key may enable the authenticated user to access the encrypted data stored at the storage device. Other embodiments may be described and/or claimed.

摘要： The present invention concerns an injection device with a housing adapted to receive a syringe having a discharge nozzle, the housing having an indicator opening. There is a trigger and a forward drive arranged to act upon the syringe on actuation of the trigger to advance the syringe from a retracted position to an extended position thereby discharging the contents of the syringe through the discharge nozzle. A support member is in contacting juxtaposition with the housing and a return drive is supported by the support member and arranged to act upon the syringe after the contents of the syringe has been discharged so that the syringe can be withdrawn from the extended position to the retracted position. Advantageously, the support member is arranged in the housing so that the second drive does not obscure an inspection of the contents of the syringe through the indicator opening. Hence, it can be clearly determined whether the contents of the syringe have been expelled from the syringe.

摘要： A system for coordinating the submission and processing of a bill according to predictive payment data of a plan. The system comprises a provider interface and an integrated database for receiving a predictive payment plan submitted from the provider interface. The system also has a predictive payment request of the plan storable in the database, the request including a plurality of predictive payment parameters. An adjudication engine is coupled to the integrated database, and an insertion function is used for inserting the predictive payment parameters into an adjudication rule set of the adjudication engine. The adjudication rule set is used for eventual adjudication of the predictive payment data, wherein adjudication of the predictive payment data results in the generation of the bill. The system also has a workflow engine for coordinating the processing of the electronic bill and for updating the bill information in response to processing.

摘要： A docking system includes a mobile robotic device and a charging station to which the robotic device is to dock. The robotic device is comprised of sensors to capture a homing signal emitted by the charging station, docking logic that processes the homing signal so that it can be used to control the movements of the robotic device towards and dock with the charging station, and it is comprised of a mechanism for receiving a cylindrical charging post. The charging station is comprised of a circular platform in the center of which is located the charging post that is generally cylindrical in shape. The charging post includes a charging contact, ground contacts and an IR emitter. The geometry of the receiver mechanism elements and the shape of the charging post and geometry of the charging station generally permits the robotic device to approach the charging station and to dock with the charging station from any angle.
