Patent ID: 8469921

Claim:
A receiver for detection of physiological information associated with a subject, the receiver comprising: a power source secured within a housing; a power management module electrically coupled to the power source and secured within the housing such that the power management module controls the power source; a processing unit electrically coupled to the power management module and secured within the housing, wherein the processing unit is configured to detect a first signal having a first frequency and corresponding to a first current flow produced by a device internal to the subject and a second signal having a second frequency and corresponding to a second current flow associated with the subject's physiology, wherein the first frequency is greater than the second frequency; and a communication module electrically coupled to the processing unit and secured within the housing, wherein the communication module allows for communication between the receiver and a device external to the subject such that the receiver is able to provide the physiological information to the external device and to provide control information to another external device based on the physiological information; wherein the power management module comprises a beacon switching module that generates a signal that allows the power management module to transition an operational state of the receiver depending on the first signal; and wherein the power management module comprises: a high power operation module that controls high power output from the power supply to the processing unit when the processing unit is in an active state; an intermediate power operation module that controls intermediate power output from the power supply to the processing unit while the processing unit is in an active nonoperation state; and a lower power operation module that controls low power output from the power supply and monitors the subject's skin for the high frequency current flow while the processing unit is in an inactive state.
