  • AUTOMATIC CONFIGURATION OF A COMPUTER SYSTEM BASED ON PROCESS MODELING OF AN IMPLEMENTED PROCESS
    Publication number: 20150006878
    Abstract: A configuration architecture automatically links the output of a business process modeler to a business system configuration tool. The output of the business process modeler is translated into a representation of a source business process that is used by the business system configuration tool to automatically generate configuration templates. A user can provide configuration information through the configuration templates. The configuration inputs are applied to an implementation of a business system to obtain a configured, working business system instance with the same functionality as the source business process.

  • System for Maintaining the Integrity of a Tour Group
    Publication number: 20140347973
    Abstract: A group of tourists traveling, for example, in a foreign land needs to be sure that no-one becomes lost. Embodiments of the present invention take advantage of mobile wireless terminals colloquially known as “smartphones” to quickly identify any members of a tour group that stray from the group, and to help them rejoin the group. Also, with the assistance of a Central Command Center, appropriate authorities such as a tour leader or relatives can be automatically notified, and search operations initiated if needed.

  • MULTIPLE OUTER LOOP LINK ADAPTATION
    Publication number: 20140126467
    Abstract: Systems and methods for subframe-based link adaptation for a radio signal in a cellular communications network are disclosed. In one embodiment, a base station obtains a hybrid automatic repeat request acknowledgement for data transmitted between the base station and a mobile terminal in a radio signal of the base station. The base station then updates a parameter (e.g., SINR offset) used to control a Modulation and Coding Scheme (MCS) for transmission of data between the base station and the mobile terminal in the radio signal for one or more subframes in a frame structure of the radio signal based on the hybrid automatic repeat request acknowledgement. The one or more subframes are a subset of all of the subframes in the frame structure of the radio signal.
