Abstract: A method with which mechanical properties of the interface of the fiber reinforced thermoplastic resin matrix composite material can be improved by conducting grafting on surfaces of materials. A carbon fiber (CF) and a polymethyl methacrylate resin (PMMA) are subjected to interface modification treatment to introduce active carboxyl groups to the surfaces of the materials. Then, hexamethylene diisocyanate (HDI) is used as a coupling layer for connecting the carboxyl groups on the surfaces of the carbon fiber and on the surfaces of the polymethyl methacrylate resin to form a “molecular bridge”. Accordingly, the interface binding force between the resin and the fiber is improved by chemical grafting. A modified carbon fiber reinforced polymethyl methacrylate composite material sample (CF/PMMA) is prepared by a thin film lamination method, and the composite material sample prepared is subjected to a microscopic verification testing of the validity of the method provided in the present disclosure.

Abstract: There are provided systems and methods for load balancing for map application route selection and output. A user may utilize a device application to map or route between two or more endpoints, such as geo-locations entered or detected by the device. During calculation of a travel route between the endpoints, real-time data, user preferences, and requesting entities may provide criteria data that may cause determination of a particular travel route, where the travel route may be longer than a most efficient route but within a pre-defined variable time or distance allotment and match the criteria data. Use of the route may accrue a form of compensation for the user. The user may view an application interface displaying the route, which may further include one or more executable processes to cause recalculation of the route. Recalculation of the route may require the user to provide credits or compensation.

Abstract: A computer system monitors usage of an application on a computing device to identify one or more pre-fetch situations corresponding to a user of the computing device. The computer system determines whether the computing device is in a situation that corresponds to at least one of the identified one or more pre-fetch situations. In response to determining that the computing device is in the situation that corresponds to the at least one of the identified one or more pre-fetch situations, the computer system causes data corresponding to the application to be pre-fetched.

Abstract: Exemplary embodiments are directed to a method for allowing a user at a first client device to provide access to restricted content on a content provider server to a user at a second client device without providing identifying information of the second client device or the user to the content provider. The content provider receives a request from a messaging app on a first client device for sharing of a content item with a second client device and generates a metadata block comprising at least a link to the content item. The metadata block is sent to the first client device and, in response, a public key of a private/public key pair of the second client device is received from the first client device. A request for the content item, is then received and contains a data item digitally signed using the private key of the private/public key pair of the second client device. The public key is then used to verify the digitally signed data item, thereby confirming the identity of the second client device.

Abstract: A system includes a service provider device and a point of sale (POS) device. A session between a user device and the POS device is established. An authentication request associated with the user device is provided via a user interface of the POS device. Subsequent to an authentication of information, responsive to the authentication request, the POS device receives funding instrument (FI) proxy information corresponding to FIs, which is unusable to identify the FIs by a merchant. A selectable representation corresponding to the FI proxy information is provided via the user interface. Responsive to receiving an indication of a selected member from the selectable representation, information for the selected member is sent. The service provider device determines that the session corresponds to an account associated with the user device and the merchant, and performs a transaction for the session using a first FI that corresponds to the selected member.

Abstract: Systems and methods for an account integration system include establishing, by a service provider device, a first session with a service provider account associated with a user. After determining that a second session between a user device and the third party account of the user is active, a first validation is caused to access third party account information associated with the second session. The third party account information and the service provider account information are concurrently displayed by a display interface of the service provider device. A transaction request for a transaction associated with the service provider account and the third party account of the user is received. Information is sent to cause a second validation of the transaction request by a provider of the third party account. In response to the second validation of the transaction request, the requested transaction is processed.

Abstract: Exemplary embodiments are directed to a method for allowing a user at a first client device to provide access to restricted content on a content provider server to a user at a second client device without providing identifying information of the second client device or the user to the content provider.

Abstract: Exemplary embodiments relate to methods and systems for transferring a user's messaging history from one device to another. A user's primary device, storing the official truth of the user's messaging history, establishes an end-to-end encrypted session with a new device, using a first decryption key during initial session setup. The primary device may conglomerate all or a portion of the messages comprising the user's messaging history into a data blob which is encrypted and sent to a blob store. An E2E encrypted message is sent from the primary device to the new device, via an intermediate server. The E2E encrypted message includes a second key for decrypting the data blob and a pointer to the location of data blob on the blob store. The new device retrieves the data blob from the blob store and decrypts the data blob using the second key to extract plaintext versions of the user's messages and adds the messages to the messaging application on the new device.

Abstract: There are provided systems and methods for local digital token transfer during device communication limitations. A first computing device of a first user may include applications and data necessary to generate and/or transmit a data token to a second device to provide particular data to the second device, including a token used for electronic transaction processing. The first device may be unable to communicate with the second device in particular instances, for example, if the first device becomes non-operational due to battery power, location specific requirements, or other operation issue. Thus, the first device may store the token locally or to a nearby associated device, such as a keyfob device or other transceiver. The token may then be available to a third device when the first device is limited from communications, which may be used to communicate the token to the second device.
