Abstract: Systems and methods provide a targeted and secure software image or other data to a television receiver. The data item can be provided to the smart card through a television service provider distribution system in blocks of data that are small enough to be processed by the smart card. For each block of data, the smart card can decrypt the block of data with a global network key, generate a partial hash representing the block of data, update a full hash with the partial hash, encrypt the block of data with a dynamically generated item key, and transmit the encrypted block of data to the television receiver. Once complete, the smart card can security check the software image including an integrity check using the full hash. If the security check passes, the smart card can transmit the dynamically generated item key to the television receiver.

Abstract: Described herein are systems and methods for securing transmission of content from a smart card in a host television receiver to a client television receiver. The smart card can receive the encrypted content stream from the television service provider, decrypt the content stream with the global network key, identify the client television receiver as the destination of the content stream, generate a unique key specific to the content stream, encrypt the unique key with a local key known to the client television receiver, encrypt the content stream with the unique key, and transmit the encrypted content stream along with the encrypted unique key to the client television receiver. The client television receiver can then receive the encrypted content stream and the encrypted unique key, decrypt the unique key, decrypt the content stream with the unique key, and transmit the content stream to a display device of the client television receiver.

Abstract: Various embodiments provide a dual purpose press-bar and heat sink for an integrated circuit card (ICC) reader. The dual purpose press-bar and heat sink provides two functions. First, the dual purpose press-bar and heat sink conducts and dissipates internal heat generated by a high data transfer ICC inserted in to the ICC reader. Second, the dual purpose press-bar and heat sink ensures that contact pads of the high data transfer ICC create reliable electrical connections with ICC contacts of the ICC reader. As such, the dual purpose press-bar and heat sink simultaneously dissipates heat from a high data transfer ICC and ensures that a high data transfer ICC maintains proper electrical connections with ICC contacts of an ICC reader.

Abstract: Various arrangements for avoiding obstacles for a visually-impaired pedestrian are presented. An m by n matrix of distance measurements may be created using a scanning time of flight (ToF) sensor component for various different directions. The m by n matrix of distance measurements and the m by n direction matrix may be analyzed to identify a first obstacle having a vertical height that differs by at least a predefined threshold measurement from a neighboring second region. Based on identifying the first obstacle, an indication of the first obstacle and an indication of the distance to the first obstacle determined using the m by n matrix of distance indications may be output.

Abstract: Various embodiments provide a card reader that provides heat dissipation for high data transfer ICCs. The card reader includes a body having a press bar that physically contacts an upper surface of the ICC when fully inserted into the card reader. The press bar includes an aperture directly overlying and aligned with the card contacts of the card reader and the contact pads of the ICC when fully inserted. The aperture allows any heat generated by the ICC to radiate to a surrounding cooling medium, such as air.
