    摘要： A receiver front end receives a local frequency reference signal and a Frequency Shift Keying modulated signal comprising a synchronisation sequence, and downconverts the Frequency Shift Keying modulated signal to provide baseband in-phase and quadrature signals. A pulse generator receives the in-phase and quadrature signals, generates an in-phase pulse signal ILEAD comprising pulses aligned with edges of the baseband in-phase and quadrature signals when the baseband in-phase signal leads the baseband quadrature signal, and generates a quadrature pulse signal QLEAD comprising pulses aligned with edges of the baseband quadrature and in-phase signals when the baseband quadrature signal leads the baseband in-phase signal. A frequency corrector receives the in-phase and quadrature pulse signals during receipt of the synchronisation sequence, compares the pulse signals to a target, and generates a control signal for controlling the local signal generator in dependence upon the result of the comparison.

    摘要： A vital-signs patch in a patient monitoring system is disclosed. The patch includes a housing configured to be attached to the skin of a patient, the housing containing a radio that can selectably transmit and receive on more than one frequency and a processor. The processor configures the radio to transmit and receive on a determined frequency based at least in part on the level of noise detected on the frequencies.
