Noise and interference can be independently measured in a multiple user Orthogonal Frequency Division Multiplexing (OFDM) system. Co-channel interference is measured in a frequency hopping, multiple user, OFDM system by tracking the sub-carriers assigned to all users in a particular service area or cell. The composite noise plus interference can be determined by measuring the amount of received power in a sub-carrier whenever it is not assigned to any user in the cell. A value is stored for each sub-carrier in the system and the value of noise plus interference can be a weighted average of the present value with previously stored values. The noise component can be independently determined in a synchronous system. In the synchronous system, all users in a system may periodically be prohibited from broadcasting over a sub-carrier and the received power in the sub-carrier measured during the period having no broadcasts.

This roaming profile client alters the settings for the application on the second client computer such that, when the user session executes the application on the second client computer, the application reflects the change.

Dynamic registration of event handlers in a computer application or operating system recognizes multiple synchronous input streams by identifying each new stroke in a frame representing a single moment in time and mapping in a registration process each identified new stroke to a listening process that is associated with the user interface element to which the new input stream is to be applied. In the same frame, released strokes are unmapped and then each active listening process is called to carry out a respective control operation. When called, the strokes have the correct data for the given frame. The process is repeated for subsequent frames. By carrying out various processes in a sequence of frames, the concept of concurrency is preserved, which is particularly beneficial to multi-touch and multi-user systems.
