A system and method for wireless communication. The system can include a transmitter that transmits a data signal having a time period without data transmission. The system can also include a receiver including a first antenna, a second antenna, a switch that activates one of the first antenna and the second antenna, and a processor that estimates a first signal-to-noise ratio for the first antenna and a second signal-to-noise ratio for the second antenna during the time period without data transmission. The processor can control the switch to select one of the first antenna and the second antenna based on a comparison between the first signal-to-noise ratio and the second signal-to-noise ratio.

Antenna selection system and method

A method and apparatus for monitoring and/or quantitatively measuring a patient's respiration using a flexible piezoelectric film sensor. The apparatus includes a piezoelectric film which converts acoustical waves generated by the patient's respiration into electrical signals. The piezoelectric film sensor can be used to monitor the respiration of a patient by correlating the sound generated in the patient's airway with respiratory activity. Further, the data generated by the sensor may be further analyzed by a patient monitor to diagnose respiratory conditions.
