## Abstract

A monitoring device obtains an image stream of at least a part of a room of a patient. The monitoring device identifies, from a first image of the image stream, first states of the part of the room. The monitoring device identifies, from a second image of the image stream, second states of the part of the room. The monitoring device compares the first states to the second states to identify a change indicating an active state. The monitoring device transmits, in response to identifying the active state, a notification to a server. The server transmits, in response to receiving the notification, an alert to a user device associated with a healthcare provider.

## Claims

### Claim 1

A method, comprising:
obtaining, by a monitoring device, an image stream of at least a part of a room of a patient;
identifying, by the monitoring device from a first image of the image stream, first states of the part of the room;
identifying, by the monitoring device from a second image of the image stream, second states of the part of the room;
comparing, by the monitoring device, the first states to the second states to identify a change indicating an active state;
transmitting, by the monitoring device in response to identifying the active state, a notification to a server; and
transmitting, by the server in response to receiving the notification, an alert to a user device associated with a healthcare provider.

### Claim 2 (depends on 1)

The method of claim 1, wherein the notification includes the second image.

### Claim 3 (depends on 1)

The method of claim 1, further comprising displaying, on the user device, the second image along with details of the active state.

### Claim 4 (depends on 1)

The method of claim 1, further comprising categorizing the active state into one of predefined health or safety concerns.

### Claim 5 (depends on 4)

The method of claim 4, wherein the predefined health or safety concerns include potential fall risk, bed sore risk, or unattended patient movement.

### Claim 6 (depends on 1)

The method of claim 1, further comprising applying a multi-label image classification model to obtain the first states and the second states.

### Claim 7 (depends on 1)

The method of claim 1, wherein the active state is determined based on a difference in patient position.

### Claim 8 (depends on 1)

The method of claim 1, wherein the active state is determined based on a difference in a condition of the room.

### Claim 9 (depends on 1)

The method of claim 1, further comprising generating a summary report of active states identified during a monitoring period.

### Claim 10 (depends on 1)

The method of claim 1, wherein the alert to the healthcare provider includes options to acknowledge the alert, request further information, or initiate a communication with the room.

### Claim 11

A system for monitoring patient environments, comprising:
a monitoring device configured to:
obtain an image stream of at least a part of a room of a patient;
identify first states of the part of the room from a first image of the image stream;
identify second states of the part of the room from a second image of the image stream;
compare the first states to the second states to identify a change indicating an active state; and
transmit a notification in response to identifying the active state to a server;
the server configured to:
receive the notification from the monitoring device; and
transmit an alert in response to the notification to a user device; and
the user device associated with a healthcare provider configured to
receive the alert from the server.

### Claim 12 (depends on 11)

The system of claim 11, wherein the notification includes the second image.

### Claim 13 (depends on 11)

The system of claim 11, wherein the user device is further configured to display the second image along with details of the active state.

### Claim 14 (depends on 11)

The system of claim 11, wherein the monitoring device is further configured to categorize the active state into one of predefined health or safety concerns.

### Claim 15 (depends on 14)

The system of claim 14, wherein the predefined health or safety concerns include potential fall risk, bed sore risk, or unattended patient movement.

### Claim 16 (depends on 11)

The system of claim 11, wherein the monitoring device is further configured to apply a multi-label image classification model to obtain the first states and the second states.

### Claim 17 (depends on 11)

The system of claim 11, wherein the active state is determined based on one of a difference in patient position or a difference in a condition of the room.

### Claim 18

Non-transitory computer-readable media having stored thereon instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
obtaining, by a monitoring device, an image stream of at least a part of a room of a patient;
identifying, by the monitoring device from a first image of the image stream, first states of the part of the room;
identifying, by the monitoring device from a second image of the image stream, second states of the part of the room;
comparing, by the monitoring device, the first states to the second states to identify a change indicating an active state;
transmitting, by the monitoring device in response to identifying the active state, a notification to a server; and
transmitting, by the server in response to receiving the notification, an alert to a user device associated with a healthcare provider.

### Claim 19 (depends on 18)

The non-transitory computer-readable media of claim 18, wherein the operations further comprise displaying on the user device, the second image along with details of the active state.

### Claim 20 (depends on 18)

The non-transitory computer-readable media of claim 18, wherein the operations further comprise categorizing the active state into one of predefined health or safety concerns.
