摘要： Mobile devices (121, 122, . . . , 12n) are handed off in overlapping cells (181, 182, . . . , 18n) by tracking a velocity (speed and direction) of movement of any number of the mobile devices (121, 122, . . . , 12n). Access points (141, 142, . . . , 14n) are each located in an associated operational cell (181, 182, . . . , 18n) and each operates at a dedicated frequency. The initial signal strengths are measured in advance at predefined locations within a defined space (16) to define signal strengths as location map (42). A nearby initial access point (typically the nearest) and at least two nearby (typically next nearest) access points are assigned for one of the mobile devices (121, 122, . . . , 12n), and the frequencies of each access point identified. A tracking processor (50) periodically scans the frequencies of the nearby access points to determine the location velocity of the mobile device and predict when a handoff will be appropriate. E.g., the actual signal strength measurements between the mobile device and the nearby access points are collected and analyzed to determine a proper time for a handoff of one or more of the nearby access points.

摘要： A method of processing data in a data processor comprising at least two data processing units. The method comprises performing different data processing steps in the data processing units concurrently during a parallel operation, and replicating performances of selected identical data processing steps in the data processing units during a non-synchronised redundant operation. The non-synchronised redundant operation comprises an initial performance of the selected identical data processing steps in one of the data processing units and a replicate performance of the data processing steps starting later than the initial performance, preferably in another of the data processing units. Initial result data representative of results from the initial performance are registered, and compared with replicate result data representative of results from the replicate performance, and an error signal is produced in case of discrepancy.

摘要： A circuit comprises a clock tree for distributing a clock signal. A first counter is arranged at a first point in the clock tree. Upon detecting a triggering edge in the clock signal, the first counter sets a first current count equal to a first delayed count. After a first delay, the first counter sets the first delayed count equal to the first current count plus an increment. A second counter is arranged at a second point in the clock tree. Upon detecting a triggering edge in the clock signal, the second counter sets a second current count equal to a second delayed count. After a second delay, the second counter sets the second delayed count equal to the second current count plus the increment. A comparator compares the first current count and the second current count. The first point and the second point are not the same, or the second delay is longer than the first delay.
