## Abstract

Systems and methods are provided for determining whether and/or when a patient is taking his or her medication and, when appropriate, providing reminders and/or alerts to the patient to improve adherence to a medication regimen. In some embodiments, a medication container is provided that includes a capacitance sensor for sensing the contents of the medication container (e.g., pill count or quantity of liquid medication). The capacitance sensor may include interleaved or interdigitated electrodes oriented vertically, horizontally, or angularly (e.g., diagonally) relative to an axis of the medication container. Reminders and/or alerts to the patient may be triggered based at least in part on the contents of the medication container, when a cap of the container was last opened and/or closed, the location of the medication container, and/or the container's surroundings.

## Claims

### Claim 1

A medication container, comprising:
a housing for medication;
a cap removably coupled to the housing;
a cap sensor configured to sense opening and/or closing of the cap;
a measurement sensor coupled to the housing for sensing a quantity of medication within the housing; and
a processor configured to trigger a reading of the measurement sensor based at least in part on a status of the cap sensor.

### Claim 2

(canceled)

### Claim 3

(canceled)

### Claim 4 (depends on 1)

The medication container of claim 1, wherein the measurement sensor comprises a weight sensor.

### Claim 5 (depends on 1)

The medication container of claim 1, further comprising a transmitter for wirelessly transmitting data regarding the reading of the measurement sensor to a remote computer.

### Claim 6 (depends on 5)

The medication container of claim 5, further comprising:
a wireless receiver configured to receive an activation command from or otherwise initiated by the remote computer;
a processor; and
an alert,
wherein the processor is configured to activate the alert based at least in part on receipt of the an activation command by the wireless receiver.

### Claim 7 (depends on 6)

The medication container of claim 6, wherein the alert comprises at least one of a light source, a graphical display, a text display, and a speaker.

### Claim 8

A medication container, comprising:
a housing for medication; and
a capacitance sensor coupled to the housing for sensing a capacitance corresponding to a quantity of the medication within the housing, the capacitance sensor comprising a plurality of conductive electrodes arranged in an interleaved pattern.

### Claim 9 (depends on 8)

The medication container of claim 8, wherein the capacitance sensor comprises:
a first conductive electrode in electrical communication with a first conductive terminal; and
second and third conductive electrodes in electrical communication with a second conductive terminal,
wherein the first conductive electrode is positioned in between the second and third conductive electrodes, and wherein the capacitance attributable to the quantity of the medication within the housing is sensed in between the first conductive terminal and the second conductive terminal.

### Claim 10

(canceled)

### Claim 11 (depends on 8)

The medication container of claim 8, wherein the interleaved pattern of conductive electrodes comprises rectangularly shaped or generally rectangularly shaped conductive electrodes.

### Claim 12 (depends on 8)

The medication container of claim 8, wherein at least one of the plurality of electrodes is positioned in parallel or generally parallel to a vertical axis of the medication container when the medication container is in an upright position.

### Claim 13 (depends on 8)

The medication container of claim 8, wherein at least one of the plurality of electrodes is positioned perpendicular or generally perpendicular to a vertical axis of the medication container when the medication container is in an upright position.

### Claim 14 (depends on 8)

The medication container of claim 8, wherein at least one of the plurality of electrodes is positioned in an angular relationship to a vertical axis of the medication container when the medication container is in an upright position, wherein the angular relationship is non-parallel and non-perpendicular.

### Claim 15

(canceled)

### Claim 16 (depends on 8)

### Claim 18

(canceled)

### Claim 19 (depends on 8)

The medication container of claim 8, further comprising a capacitance to digital converter for converting the capacitance sensed by the capacitance sensor into digital data.

### Claim 20 (depends on 8)

The medication container of claim 8, further comprising at least one alert configured to be activated based at least in part on the capacitance corresponding to the quantity of the medication sensed by the capacitance sensor.

### Claim 21

compare data indicative of when a communication was last received by the one or more computers from the medication container to the data indicative of the medication regimen associated with the patient; and
based at least in part on the comparison, trigger a reminder to the patient to consume the medication.

### Claim 22 (depends on 21)

The system of claim 21, wherein the one or more computers are further configured to:
receive a communication from the medication container comprising data indicative of a quantity of medication within the medication container at a given time;
compare the data indicative of the quantity of the medication within the container to the data indicative of the medication regimen associated with the patient; and
based at least in part on the quantity of medication comparison, trigger a reminder to the patient to consume the medication.

### Claim 23 (depends on 21)

The system of claim 21, wherein the one or more computers are configured to communicate a signal to the medication container that activates an alert by the container.

### Claim 24 (depends on 21)

The system of claim 21, wherein the one or more computers are configured to initiate a digital message to a user computer associated with the patient.

### Claim 25

A method for reminding a patient to consume a medication, comprising:
storing in computer memory data indicative of a medication regimen associated with a patient;
receiving with one or more computers one or more electronic communications from a medication container associated with the patient;
comparing with the one or more computers data indicative of when a communication was last received by the one or more computers from the medication container to the data indicative of the medication regimen associated with the patient; and
based at least in part on the comparison, triggering with the one or more computers a reminder to the patient to consume the medication.

### Claim 26 (depends on 25)

The method of claim 25, further comprising:
receiving with the one or more computers an electronic communication from the medication container comprising data indicative of a quantity of medication within the medication container at a given time;
