Abstract:

A method and system for acknowledging the receipt of a transmitted data stream in a wireless personal area network (WPAN) are disclosed. In one embodiment, a plurality of medium access control (MAC) protocol data units (MPDUs) are transmitted from a transmitting party to a receiving party, and the receiving entity sends a delayed acknowledgment frame to the transmitting party using a bitmap field for each of the fragmented packets instead of using two bytes of an MPDU block for acknowledging each received MPDU. The bitmap field includes a plurality of bitmap values corresponding to the plurality of MPDUs, and each of the plurality of bitmap values is indicative of whether each of the MPDUs is received or not.

Abstract:

Improved negative electrodes can comprise a silicon based active material blended with graphite to provide more stable cycling at high energy densities. In some embodiments, the negative electrodes comprise a blend of polyimide binder mixed with a more elastic polymer binder with a nanoscale carbon conductive additive. The silicon-based blended graphite negative electrodes can be matched with positive electrodes comprising nickel rich lithium nickel manganese cobalt oxides to form high energy density cells with good cycling properties.

Abstract:

A merchant website includes a QR code button to initiate a payment transaction. The QR code button is selected by a consumer at checkout. If selected, a QR code is generated on a second computing device. The QR code is displayed on a second computing device and contains embedded data such as a token for a PAN stored in a memory of the second computing device and two cryptograms. A webcam in communication with the first computing device is used to scan the QR code. The data embedded in the QR code is passed from the second computing device to the merchant website via the first computing device and used to complete the payment transaction.

Abstract:

Embodiments of the invention are directed to methods, systems and devices for providing sensitive user data to a mobile device using an encryption key. For example, a mobile application on a mobile device may receive encrypted sensitive user data from a mobile application server, where the user sensitive data is encrypted with a key from a token server computer. The mobile application may then request that the encrypted payment information be sent to the token server. The mobile device may then receive a payment token associated with the payment information from the token server.
