## Abstract

A compact integrated patch may be used to collect physiological data. The patch may be wireless. The patch may be utilized in everyday life as well as in clinical environments. Data acquired by the patch and/or external devices may be interpreted and/or be utilized by healthcare professionals and/or computer algorithms (e.g., third party applications). Data acquired by the patch may be interpreted and be presented for viewing to healthcare professionals and/or ordinary users.

## Claims

### Claim 1

An integrated patch comprising:
a base comprising electrodes, wherein the electrodes are configured to gather information sufficient to generate at least three limb lead signals, wherein the base has a diameter of less than or equal to 5 inches;
a cover coupled to the base;
one or more non-electrode sensors configured to gather other information;
an electronic module in communication with the electrodes, wherein the electronic module is housed between the base and the cover, wherein the electronic module comprises (i) a first instrumentation amplifier configured to receive and amplify signals from a first electrode and a second electrode of the electrodes to generate a first differential input signal and (ii) a second instrumentation amplifier configured to receive and amplify signals from a third electrode and the second electrode of the electrodes to generate a second differential input signal wherein the at least three limb lead signals are generated by calculating differentials between the first differential input signal, the second differential input signal, and a third input signal; and
a radio in communication with the electronic module, the radio configured to wirelessly transmit or receive data.

### Claim 2 (depends on 1)

The patch of claim 1, wherein the base comprises a fourth electrode configured to reduce a noise of acquired signals.

### Claim 3 (depends on 2)

The patch of claim 2, wherein the base comprises a fifth electrode configured to reduce a noise of acquired signals, and wherein the fourth and fifth electrodes are located within at least 1.5 inches of each other.

### Claim 4 (depends on 1)

The patch of claim 1, wherein the one or more non-electrode sensors comprise sensors configured to gather information regarding heart rate or respiration of a user.

### Claim 5 (depends on 1)

The patch of claim 1, wherein the one or more non-electrode sensors comprise sensors configured to gather information regarding one or more members selected from the group consisting of (i) ambulatory data of a user, (ii) hydration, temperature, SpO2, or blood pressure of a user, and (iii) acceleration, audio, vision, or pressure of an environment around the patch.

### Claim 6 (depends on 1)

The patch of claim 1, wherein the patch is configured to communicate with one or more external devices via the radio.

### Claim 7 (depends on 6)

The patch of claim 6, wherein the one or more external devices comprise cell phones, tablet, PDAs, or fitness trackers.

### Claim 8 (depends on 1)

The patch of claim 1, further comprising a spacer configured to separate the base from the cover, wherein the spacer defines a space in which the electronic module is to be located in.

### Claim 9 (depends on 1)

The patch of claim 1, wherein the electronic module is removably coupled to the base.

### Claim 10 (depends on 1)

The patch of claim 1, further comprising one or more processors individually or collectively configured to analyze or process gathered information.

### Claim 11 (depends on 1)

The patch of claim 1, further comprising a visual, auditory, or haptic alert system configured to send an alert to a user based on gathered information.

### Claim 12 (depends on 1)

The patch of claim 1, wherein the cover comprises one or more indicators associated with a preferred location or orientation of the patch.

### Claim 13 (depends on 1)

The patch of claim 1, wherein four or fewer electrodes are arranged in a rectangular pattern and are configured to gather information sufficient to generate the at least three limb leads.

### Claim 14 (depends on 12)

The patch of claim 12, wherein the one or more indicators visually respond to a correct placement of the patch on a user, thereby visually distinguishing between correct placement and incorrect placement of the patch on the user.

### Claim 15 (depends on 12)

The patch of claim 12, wherein the preferred location is near a center of a chest or near an upper left chest of a human being.

### Claim 16 (depends on 12)

A method of placing the integrated patch of claim 12 on a user comprising:
matching the preferred location or orientation of the patch to a provided figure;
placing the patch on the user at the preferred location or orientation.

### Claim 17 (depends on 1)

The patch of claim 1, wherein the electronic module comprises fewer instrumentation amplifiers than a number of the electrodes, which fewer instrumentation amplifiers are configured to generate the at least three limb lead signals.

### Claim 18 (depends on 1)

The patch of claim 1, wherein the electronic module comprises fewer instrumentation amplifiers than a number of the at least three limb lead signals generated.

### Claim 19 (depends on 1)

The patch of claim 1, wherein the electronic module is configured to generate augmented limb lead signals.

### Claim 20 (depends on 1)

The patch of claim 1, wherein the third input signal is zero.
