Extendable modular tracking device

A method for providing a tracking device, the method comprising:

• providing an internal sensor configured to sense a first electrical signal indicative of at least one of a physiological parameter of a user, a behavioral parameter of the user, and an environmental parameter;
• providing a receiver including a first electrical contact and a second electrical contact, the first electrical contact and the second electrical contact being configured to receive, via a wire, a second electrical signal from an external device, the electrical signal being indicative of the at least one of the physiological parameters of the user, the behavioral parameter of the user, and the environmental parameter;
• and
• providing a controller coupled to the receiver, wherein the controller is configured to:
• analyze the first electrical signal data from the internal sensor to determine first data;
• detect a presence of the second electrical signal in the first electrical contact and the second electrical contact;
• identify, based on the second electrical signal, the external device;
• analyze, based on a result of the identification, the second electrical signal to determine second data;
• and
• perform a combined analysis of the first data and the second data to determine at least one additional value of the at least one of the physiological parameter of the user, the behavioral parameter of the user, or the environmental parameter.

• detect a presence of the second electrical signal in the first electrical contact and the second electrical contact;
• upon detection of the presence of the second electrical signal, determine, based on a portion of the second electrical signal, a type of the electrical signal;
• based on the type of the second electrical signal, selectively switch the receiver to receive the rest of the second electrical signal in one of a digital mode or an analog mode;
• identify, based on the second electrical signal, the external device;
• and
• analyze, based on a result of the identification, the second electrical signal to determine second data;
