A re-wearable wireless device includes a reusable component to be secured to a disposable component. The reusable component includes a sensor interface to receive signals from an electrode secured to a living subject and monitors physiological and physical parameters associated with the living subject and a cellular wireless communication circuit. An adhesive base the device includes a first adhesive layer and a second adhesive layer partially covering the first adhesive layer around a perimeter thereof, where the first and second adhesive layers include different adhesives. A method of establishing a link between two wireless devices is also disclosed, where a first wireless device with an insignia representing a communication channel address identification is provided. An image of the insignia is captured with a mobile telephone computing device comprising an image sensor. The captured image is processed to extract the communication channel address identification represented by the insignia.



Claim 1:


1. A device comprising:

a disposable component comprising:

a mechanical snap-in connect mechanism comprising:

a base portion comprising a first electrical contact and a second electrical contact; and

a pair of projecting elements that are connected to the base portion and extend from the base portion, wherein the pair of projecting elements extend along opposite edges of the base portion and are substantially parallel to each other, and the first and second electrical contacts are arranged between the projecting elements and along a line substantially parallel to the projecting elements; and

a first electrode electrically coupled to the first electrical contact and a second electrode electrically coupled to the second electrical contact, wherein the first electrode and the second electrode are configured to be secured to a living subject; and

a reusable component configured to operably engage the projecting elements and configured to be secured to the disposable component when the reusable component is engaged with the projecting elements and at least a portion of the reusable component is located between the projecting elements, the reusable component comprising:

a sensor interface configured to receive signals from the first and the second electrodes configured to be secured to the living subject and monitor one or more physiological and physical parameters associated with the living subject, wherein the sensor interface comprises a third electrical contact and a fourth electrical contact on a surface of the reusable component, wherein the third and fourth electrical contacts are arranged such that when the reusable component is attached to the disposable component, the third electrical contact is coupled to the first electrical contact, and the fourth electrical contact is coupled to the second electrical contact;

a cellular wireless communication circuit; and

a transbody conductive communication module configured to communicate with an event maker system in a body of the living subject.


Implantable pressure sensors and methods for making and using the same are provided. A feature of embodiments of the subject pressure sensors is that they are low-drift sensors. The subject sensors find use in a variety of applications.

Claim 1: 

1. A method for measuring cardiac pressure, the method comprising:

providing a power supply voltage for a number of control chips over two wires, each control chip coupled to one or more pressure sensors;
transmitting a number of bit sequences carrying address information with the power supply voltage over the two wires;

configuring a pressure sensor for measuring cardiac pressure; and

receiving a digital signal indicating a measured cardiac pressure.

The invention provides a receiver associated with a body, e.g., located inside or within close proximity to a body, configured to receive and decode a signal from an in vivo transmitter which located inside the body. Signal receivers of the invention provide for accurate signal decoding of a low-level signal, even in the presence of significant noise, using a small-scale chip, e.g., where the chip consumes very low power. Also provided are systems that include the receivers, as well as methods of using the same.


Claim 1:

1. A signal receiver comprising:

an automatic gain controller configured to receive an encoded signal from an in vivo transmitter in a low signal to noise ratio (SNR) environment and to actively adjust the signal receiver to variations in frequency and power of the received encoded signal, and wherein the automatic gain controller is configured to determine a first frequency having a highest amplitude in a power spectrum of the received encoded signal;
a demodulator coupled to the automatic gain controller and configured to receive an output signal from the automatic gain controller, wherein the output signal comprises information regarding the first frequency, and reconstruct the encoded signal locked in frequency and phase to the received encoded signal and configured to approximate an original un-encoded signal, wherein the demodulator is tuned to the first frequency such that the demodulator is configured to adapt to changes in frequency of the received encoded signal;
a symbol recovery component configured to receive the reconstructed encoded signal and determine a signal clock of the reconstructed encoded signal and identify a start sequence in the reconstructed encoded signal, and wherein the symbol recovery component is configured to determine a phase of the reconstructed encoded signal, and produce a decoded signal with substantially no error.
