Abstract: The present disclosure provides scalable nanotube fabrics and methods for controlling or otherwise adjusting the nanotube length distribution of a nanotube application solution in order to realize scalable nanotube fabrics. In one aspect of the present disclosure, one or more filtering operations are used to remove relatively long nanotube elements from a nanotube solution until nanotube length distribution of the nanotube solution conforms to a preselected or desired nanotube length distribution profile. In another aspect of the present disclosure, a sono-chemical cutting process is used to break up relatively long nanotube elements within a nanotube application solution into relatively short nanotube elements to realize a pre-selected or desired nanotube length distribution profile.

Abstract: A payment device and method and system for using the payment device is described capable of utilizing a pre-authorized amount on existing infrastructure, including POS terminals or for using offline pre-paid products on this infrastructure. The updates for the pre-authorized or offline prepaid products can be sent by the issuer and applied by the card contemporaneously with the card's processing of the issuer authentication data but without requiring any additional bytes in the issuer authentication data. The updates performed by the issuer can be larger and more extensive than could be achieved by using any available space in the issuer authentication data.

Abstract: This disclosure is directed to optical data path systems that enable unidirectional and bidirectional transmission of optical signals between nodes of a multi-node system such as a multiprocessor system. In one aspect, an optical data path system includes an optical device layer connected to nodes of a multi-node system and a controller. The optical device layer includes a waveguide network of waveguide branches optically connecting each node of the multi-node system to every other node of the multi-node system, resonators disposed adjacent to the waveguide branches, and detectors disposed adjacent to waveguide branches of the waveguide network. Each detector is electronically connected to a node of the multi-node system. The resonators are operated by the controller to control the path of optical signals sent between the nodes of the multi-node system.

Abstract: Techniques are provided for updating an offline parameter of a payment device having an online-capable application and a primarily offline application. The offline parameter can be a counter reflective of an offline spending balance. The same parameter can be shared between the applications, or cross-application visibility of the parameter can be provided. When a requirement to update the offline parameter is determined, the offline parameter can be updated substantially contemporaneously with an online transaction. The updates can be transparent to the user, allowing substantial duplication of the debit card and/or credit card experience with an offline payment device.

Abstract: Techniques are provided for transaction adjustment. A payment device, having an offline balance, is presented to an offline terminal in connection with a putative transaction. If an irregularity with the putative transaction is detected, the offline balance is adjusted responsive to the detection. In one aspect of the invention, such adjustment can be carried out, via offline-terminal interaction, substantially without the use of a security module and cryptographic keys in the offline terminal.

Abstract: Initial presentation of a payment device to a payment terminal assembly, in connection with a putative transaction, is facilitated. The payment device includes a payment device memory storing a device-side payment application, with an on-device balance, and at least one payment device processor coupled to the payment device memory. The payment terminal assembly includes a terminal memory, storing a terminal-side payment application, and at least one terminal processor coupled to the terminal memory. A first command is sent from the payment terminal assembly to the payment device to compute a cryptogram to complete the putative transaction. It is detected that the cryptogram is not received as expected. In response, an identifier of the payment device and transaction recovery data associated with the putative transaction are stored in a storage area of the terminal memory. The payment terminal assembly obtains the identifier of the payment device, upon re-presentation of the payment device to the payment terminal assembly. Upon the re-presentation of the payment device to the payment terminal assembly, the payment terminal assembly compares the obtained identifier of the payment device to contents of the storage area. Conditioned at least upon the comparing yielding a match, a second command is sent from the payment terminal assembly to the payment device. The second command instructs the payment device to re-produce the cryptogram to complete the putative transaction.
