Abstract: A control system for limiting power turbine torque (QPT) of a gas turbine engine includes a controller including a processor and memory configured to control the gas turbine engine, the controller including an engine control module that provides an effector command signal to a gas generator of the gas turbine engine; a power turbine governor module that outputs a preliminary torque request (QPT_req_pre); and a power turbine torque (QPT) optimal limiter module that outputs a maximum torque topper (QPT_max) to limit a power turbine speed overshoot of the gas turbine engine; wherein the controller outputs a minimum value between the preliminary torque request (QPT_req_pre) and the maximum torque topper (QPT_max) to the engine control module.

Abstract: A method and apparatus for changing monitoring of a cellular data connection at a mobile device, the method checking, using a processor at the mobile device, whether the mobile device is connected to both the cellular data connection and an alternative data connection; and if yes, extending the slot cycle or suspending monitoring of a slot for the cellular data connection at the mobile device.

Abstract: A method and system for data session establishment from a mobile device in a multiple networks scenario, the method including, checking whether an identifier for an first network is on a blacklist on the mobile device; if the first network identifier is not on the blacklist, attempting to establish a data connection with the first network; and if the first network identifier is on the blacklist, establishing a data connection with a second network. The method and system for data session establishment include deriving and maintaining the blacklist.
