Abstract:
1. A wireless sensor system for monitoring a physiological parameter of a subject, 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 a circuit comprising i) at least one antenna, ii) at least one radio coupled to said at least one antenna, and iii) a host interface unit that transmits data from said relay station to said host device; and at least one portable patch that is in communication with said relay station, wherein said portable patch comprises a circuit comprising i) at least one antenna, ii) at least one radio coupled to said at least one antenna, and iii) at least one sensor that collects sensor data to monitor said physiological parameter, wherein said portable patch collects sensor data from said subject using said at least one sensor and transmits said sensor data to said relay station, wherein said relay station receives said sensor data from said portable patch and transmits said sensor data to said host device in a format that is recognizable by said host device when used as a wired sensor system, 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.
