Abstract: An automated pet door system. The system provides a user programmable database and system engine for controlling the passage of selected animals through a portal, such as a door, or screen, or other passage limiting device. The system is permissionable, in that the user may provide a set of dates, times, events, or other instructions, through a user input device to establish a then current operating envelope for each of one or more selected animals. A unique identification tag, which may use active radio frequency identification tag techniques, provides identity information for each candidate animal. Multiple sensor inputs, providing information such as door position, proximity of animals to the door, and direction and velocity of animals, are provided as inputs to a decision engine, which evaluates sensor inputs over time, before determining whether to open or close the pet door.

Abstract: The present disclosure relates to systems and methods for assembling and extracting command and control data. In embodiments of the present disclosure, the command and control data is segmented and inserted into multiple packet headers. The header packets are identified by flags such as “First portion,” “Middle portion,” “Last portion,” or “Null Byte.” When a receiver extracts the command and control data from the headers, it tracks the flags associated with the headers. The command and control data is saved to buffer in association with its associated flag. The receiver uses the flags to determine when all command and control data headers have been received. The command and control data is then reconstructed and used to decrypt audio visual content.

Abstract: Systems and methods for implementing a Transport I/O system are described. Network encrypted content may be received by a device. The device may provide the network encrypted content to a secure processor, such as, for example, a smart card. The secure processor obtains a network control word that may be used to decrypt the network encrypted content. The secure processor may decrypt the network encrypted content to produce clear content. In embodiments, the secure processor may then use a local control word to generate locally encrypted content specific to the device. The device may then receive the locally encrypted content from the secure processor and proceed to decrypt the locally encrypted content using a shared local encryption key. The Transport I/O system ensures the protection of the network control word by maintaining the network control word on the secure processor.

Abstract: A diffuser seal for an aft end of a high pressure compressor of a gas turbine engine is disclosed. The diffuser seal includes a flow guide carrier coupled to the diffuser case. The flow guide carrier is also coupled to a static seal. The static seal engages a rotary seal and permits air flow through the static and rotary seals in the aft direction. The flow guide carrier is also coupled to a fairing and a fairing/hub support. The flow guide carrier supports the fairing in a spaced-apart position with respect to the rear hub so that air flowing through the static and rotary seals passes between a forward surface of the fairing and the rear hub. The fairing/hub support extends forward from the flow guide support and engages an aft surface of the fairing thereby limiting movement of the rear hub and fairing in the aft direction. This design helps to prevent parts or debris from piercing the rear hub and entering the high pressure turbine in the even of a fan blade-out or fan blade-off event.
