Abstract: Method and apparatus for transmitting credentials to a transaction processing system, the credentials arranged in sets and a set including a unique identifier and verification data elements. Credentials are activated and are then available for use in at least one subsequent transaction. In the transaction, in response to receiving authorization from a user, the unique identifier and verification data elements from a set are transmitted to the transaction processing system for the user. The credentials are activated using an activation mode selected from at least a first activation mode and a second activation mode. In the first activation mode, additional user input for the verification data elements associated with the unique identifier is received from the user. In the second activation mode, the user is authenticated, and verification data elements are received via a data communications network are received from a trusted data processing system remote from the user.

Abstract: Rotor thrust balancing systems for turbomachines and methods of using the same are generally disclosed. For example, a rotor thrust balancing system for a turbomachine, wherein the turbomachine defines a centerline extending the length of the turbomachine. The system includes a rotating drive shaft, a thrust bearing, and a first waveguide sensor. The rotating drive shaft couples a turbine section and a compressor section of the turbomachine. The thrust bearing supports the rotating drive shaft of the turbomachine. The thrust bearing includes a plurality of ball bearings, an inner race coupled to the rotating drive shaft, and an outer race coupled to a fixed structure. The first waveguide sensor is coupled to the outer race at a first end of the waveguide sensor. The waveguide sensor communicates a vibrational frequency from the thrust bearing to a second end of the waveguide sensor.

Abstract: Methods and systems described herein relate to enhancing security on a device by configuring one or more software functions in a trusted zone of a processor using object firewalls, IPC mechanisms, and/or a policy engine. An inter-process communication mechanism and inter-process communication bus enable secure inter-process communication between inter-process communication applications within the trusted zone and inter-process communication applications external to the trusted zone. Adapting, filtering, blocking, redirecting, or otherwise modifying inter-process communications is enabled by the inter-process communications mechanism. Modifications may be controlled by a policy engine within the trusted zone.

Abstract: A method, system, and computer-readable medium for synchronizing policy data on a device based on device usage context.

Abstract: A system for short-range communications includes a device and a server. The mobile device receives information via short range wireless signals, processes that information, and transmits information to the server. The server uses the information to verify that the information from the device is consistent with a device currently located in the location. Such verification may be done using cryptographic or signal processing techniques.
