摘要： A system and method for invoking one or more features of a wireless device when a signal strength of a channel approaches or drops below an RSSI threshold of the channel is disclosed. An embodiment of the invention includes the steps of (1) obtaining the RSSI threshold for the channel; (2) monitoring the signal strength during an operation mode of the wireless device; and (3) invoking the feature when the signal strength approaches a predetermined limit of the RSSI threshold. In an implementation on a cordless telephone, the feature can include playing a warning, switching to a different channel, or returning a telephone line to an idle state.

摘要： The amplitude of a swing powered by an electric motor is controlled by detecting a peak voltage induced in the motor coil by the swing motion when the motor is not being powered and comparing the detected voltage with a one of a set of pre-measured reference values of peak voltages obtained at corresponding amplitude settings to provide a signal to a motor controller which adjusts the power supplied to the motor to bring the swing amplitude to. The motor controller supplies a PWM signal voltage to power the motor and adjusts the voltage on-time to bring or restore the swing to the selected amplitude.
