When a home location server (H-LS) determines it cannot locate a subscriber device because the subscriber device is roaming, the H-LS sends an RLP request to the RLP router. The RLP router then routes the RLP request to a serving location server (S-LS), which subsequently returns location information for the roaming subscriber device. The RLP router maintains mobile switching center ID (MSCID) to location based services (LBS) mappings for routing RLP requests. The RLP router may also maintain rough MSC-level positioning data for each MSCID to enable the RLP router to resolve certain location fixes without utilizing an S-LS.

The locking element includes two opposite sliding slots each of which has a first and a second slide portion connecting each other. The locking element is adapted for sliding in the second direction such that the first and second slide portions of each sliding slot maintain a distance. The pivot element is adapted for passing through the sliding slots to be disposed at a host such that the locking element is pivotable about the pivot element. Upon positioning the pivot element at the first slide portions, the locking element is rotatable from an open position to an intermediate position. Upon sliding the locking element along the second direction to move the pivot element from the first slide portions to the second slide portions, the locking element is movable from the intermediate position to a lock position to lock the interface card.

A technique for detecting full-system idle state in an adaptive-tick kernel includes detecting non-timekeeping CPU idle state, initiating a hysteresis period, waiting for the hysteresis period to end, manipulating a data structure whose state indicates whether a scheduling clock tick may be disabled on all CPUs, and disabling the scheduling clock tick if the data structure is in an appropriate state. In a first embodiment, non-timekeeping CPUs manipulate a global counter when entering an idle state, but add hysteresis to avoid thrashing the counter. Timekeeping is turned off based on the count maintained on the global counter. In a second embodiment, a Read-Copy Update (RCU) dynticks-idle subsystem running on a timekeeping CPU manipulates a global state variable whose states indicate whether all non-timekeeping CPUs are in an idle state, and if so, for how long. Timekeeping is turned off based on the state of the global state variable.

In an actuator control method and an actuator control device, time optimal control is used, and a switching time at which an acceleration output is switched to a deceleration output, and an end time of the deceleration output are calculated using a maximum acceleration and a maximum deceleration at the time of a maximum output of a control force. A control force of an actuator is set as a maximum acceleration output from a calculation time to the switching time, the control force of the actuator is set as a maximum deceleration output from the switching time to the end time, output of the control force is ended at the end time, and the switching time and the end time are repeatedly calculated, and updated for each preset time. The control output is reduced along with decrease of residual energy, which is a sum of remaining work and kinetic energy of a control system. From this, an element of feedback control is incorporated in the time optimal control, and the control output is converged after the end of the control.
