## Abstract

Cognitive orthotics. More specifically, assistive ambulation systems and methods, including systems that can detect a person who uses an assistive ambulation device (such as a walker) and produce a signal in response to the detection, which signal is designed to encourage or motivate the person to use the device. They system may also stop the signal when the person engages the device and/or produce an additional signal or a different signal when the person engages the device.

## Claims

### Claim 1

A system comprising:
an initiator sensor configured to detect a person;
a controller couplable to the initiator sensor;
a signaling device couplable to the controller, the controller configured to cause the signaling device to produce a signal based on input received by the controller from the initiator sensor after the initiator sensor detects a person;
an engagement sensor couplable to the controller and configured such that, if coupled to an assistive ambulation device, the engagement sensor can detect if a person has engaged the assistive ambulation device; and
a power supply couplable to at least one of the controller, the initiator sensor, the signaling device, and the engagement sensor.

### Claim 2 (depends on 1)

The system of claim 1, where the controller is configured such that, when the system is coupled to or includes an assistive ambulation device, the controller prevents the signaling device from producing a signal after the engagement sensor has detected that a person has engaged the assistive ambulation device.

### Claim 3 (depends on 1)

The system of claim 1, where the controller is configured such that, when the system is coupled to or includes an assistive ambulation device, the controller causes the signaling device to produce a different signal after the engagement sensor has detected that a person has engaged the assistive ambulation device.

### Claim 4 (depends on 1)

The system of claim 1, further comprising:
an autodialer couplable to the controller.

### Claim at position 5

5-6. (canceled)

### Claim 7 (depends on 1)

The system of claim 1, further comprising:
a second signaling device couplable to the controller;
where the controller is configured such that, when the system is coupled to or includes an assistive ambulation device, the controller causes the second signaling device to produce a signal after the engagement sensor has detected that a person has engaged the assistive ambulation device.

### Claim at position 7

8-15. (canceled)

### Claim 16 (depends on 1)

The system of claim 1, further comprising:
an assistive ambulation device coupled to the initiator sensor, the controller, the signaling device, the engagement sensor, and the power supply.

### Claim at position 9

17-23. (canceled)

### Claim 24 (depends on 1)

The system of claim 1, where the controller is configured such that, when the system is coupled to or includes an assistive ambulation device, the controller can determine at least one of a distance between a person and the assistive ambulation device and a change in distance between a person and the assistive ambulation device.

### Claim at position 11

25-45. (canceled)

### Claim 46 (depends on 1)

The system of claim 1, further comprising:
a recording device couplable to the controller and configured to record information relating to the system when the system is coupled to an assistive ambulation device.
