Abstract: An example operation may include one or more of initiating a share operation, via a first mobile device, to share contact information with a second mobile device, identifying, via an application server, a first mobile device telephone number assigned to the first mobile device and a first alias telephone number to assign to the first mobile device, among available alias telephone numbers stored in a database associated with the application server, identifying, via the application server, a second mobile device telephone number assigned to the second mobile device and a second alias telephone number to assign to the second mobile device, among available alias telephone numbers stored in a database associated with the application server, and assigning the first alias telephone number to the first mobile device and the second alias telephone number to the second mobile device.

Abstract: The invention relates to computer system for controlling a user interface, the system comprising: a processor executing a calendar application as a computer program; electronic storage connected to the processor for holding user data, activity data, and activity status; a user input component configured to receive from a first user activity data defining an activity to be scheduled in a calendar, and a constraint associated with the activity; a constraint input configured to receive constraint data; wherein the calendar application is configured to process the constraint data to determine if the constraint has been met, and to set the activity status based on whether the constraint has been met and to generate control instructions for controlling a user interface to selectively present the activity to a user based on the activity status.

Abstract: Methods and apparatus for providing precision on-chip termination of transmission lines are provided which enable the termination of transmission lines using on-chip resistors configured into networks, which have resistances related to the resistance of an external reference resistor. The external reference resistor is used to configure an on-chip reference resistor network so that it has a resistance related to the resistance of the external reference resistor. Termination resistor networks are then configured so that their resistances bear a predetermined relationship to the resistance of the on-chip reference resistor network. In one embodiment the resistance of each of the termination resistor networks is substantially the same as the characteristic impedances of each of the transmission lines.
