Abstract
The present invention provides methods, devices, and systems for wireless physiological sensor patches and systems which incorporate these patches. The systems and methods utilize a structure where the processing is distributed asymmetrically on the two or more types of ASIC chips that are designed to work together. The invention also relates to systems comprising two or more ASIC chips designed for use in physiological sensing wherein the ASIC chips are designed to work together to achieve high wireless link reliability/security, low power dissipation, compactness, low cost and support a variety of sensors for sensing various physiological parameters.

55. A patch for measuring a physiological state of a patient, said patch comprising:
-
a battery and an antenna each coupled to an integrated circuit comprising a sensor interface that receives physiological signals from a sensor; a processor coupled to the sensor interface, a memory element coupled to the processor, a radio coupled to the memory element; and power management circuits that coordinate power dissipation on the patch; wherein an area of the patch multiplied by a thickness of the patch is less than about 30 cm3; and
wherein the patch is configured to permit wirelessly transmission of physiological data for at least about 2 days while monitoring a physiological signal from the patient without changing or recharging the battery. - View Dependent Claims (57, 59, 60, 61, 62, 63, 66, 67, 68, 69, 70, 71, 72, 73, 77, 78, 111, 114, 130)

139. A method for unsupervised placement of a physiological patch comprising:
-
(a) placing the patch on a patient'"'"'s body, wherein the patch can receive wireless signals from a base device, and wherein the patch comprises a visual marker to help a user orient the patch on the patient'"'"'s body; (b) initializing the patch with the base device by automatic verification of proper placement of the patch; and (c) indicating proper or improper placement of the patch to the user with an audio or visual indication.
