Abstract:
1. A system for monitoring a physiological parameter of a subject with the aid of a relay station that converts a wired sensor system into a wireless sensor system, comprising: a host device configured to monitor said physiological parameter of said subject; a relay station that is in communication with said host device wherein said relay station comprises i) at least one antenna, ii) at least one radio coupled to said at least one antenna, and iii) a host interface unit that, with the aid of said at least one radio, transmits data from the relay station to said host device, wherein said relay station is integrated as at least one application specific integrated circuit, and wherein said relay station is configured to convert a wired sensor system into a wireless sensor system; and a portable patch that is in wireless communication with said relay station, wherein said portable patch comprises i) at least one antenna, ii) at least one radio coupled to said at least one antenna, iii) at least one sensor, and iv) an application specific integrated circuit coupled to said at least one sensor, wherein, with the aid of said at least one sensor, said portable patch collects sensor data from said subject and, with the aid of said at least one radio of said portable patch, transmits said sensor data to said relay station, wherein said relay station receives said sensor data from said portable patch, rearranges said sensor data to an analog or digital format, and transmits said sensor data to said host device, and wherein said at least one radio of said relay station and said at least one radio of said portable patch are complementary radios such that, upon operation of said at least one radio of said relay station and said at least one radio of said portable patch, power is distributed asymmetrically between said relay station and said portable patch.
