## Abstract

A data file system includes one or more files about a patient wearing a wearable cardiac defibrillator (WCD) system that has been assigned to them. The one or more files contain at least one patient identifier of the patient, compliance data about a history of the patient's wearing the WCD system, and possibly other data. The data file system can be accessed through a communication network when the patient uses a communication device. When so accessed, some of the contents can be viewed on a screen of the device, for example in the form of a website. In embodiments, the health care provider and friends and family can view such data and even enter inputs, which may create a situation that motivates the patient to comply better.

## Claims

### Claim 1

A wearable cardiac defibrillator (WCD) system, comprising:
a support structure configured to be worn by a patient;
an external defibrillator configured to be coupled to the support structure and to defibrillate the patient while the support structure is worn by the patient;
a motion sensor coupled to the support structure and configured to generate motion event data;
a timer configured to determine a duration of an inert period during which a motion statistic of the motion event data is less than a motion threshold; and
an output device configured to output a human-perceptible alert in response to the duration of the inert period exceeding an inert threshold.

### Claim 2 (depends on 1)

The system of claim 1, in which
the human-perceptible alert is an audible alert.

### Claim 3 (depends on 1)

The system of claim 1, in which
the output device is a component of a communication device.

### Claim 4 (depends on 1)

The system of claim 1, further comprising:
a communication module configured to communicate through a network to a recipient alert event data about the duration of the inert period exceeding the inert threshold, and
the output device alerts the recipient.

### Claim 5 (depends on 4)

The system of claim 4, in which
the alert event data includes at least one of the motion statistic, the duration of the inert period, or the event that the duration of the inert period exceeds the inert threshold.

### Claim 6 (depends on 1)

The system of claim 1, in which
a value for the inert threshold is downloaded from a communication network.

### Claim 7 (depends on 1)

The system of claim 1, in which
an inert threshold adjust input is received, and
the inert threshold becomes adjusted to a new value responsive to the received inert threshold adjust input.

### Claim 8 (depends on 7)

The system of claim 7, further comprising:
a user interface configured to receive the inert threshold adjust input, and
the inert threshold adjust input is received via the user interface.

### Claim 9 (depends on 7)

The system of claim 7, further comprising:
a communications module configured to communicate the new value to a recipient through a network.

### Claim 10 (depends on 1)

The system of claim 1, in which
the duration of the inert period is determined as starting from a first moment,
a snooze input is received, and
the first moment becomes reset to a new value responsive to the received snooze input.

### Claim 11 (depends on 10)

The system of claim 10, further comprising:
a user interface configured to receive the snooze input, and
the snooze input is received via the user interface.

### Claim 12 (depends on 1)

The system of claim 1, in which
a Snooze-OFF input is received, and
the output device does not output the human-perceptible alert responsive to the received Snooze-OFF input even in response to the duration of the inert period exceeding the inert threshold.

### Claim 13

A method for a wearable cardiac defibrillator (WCD) system to work with an output device, the WCD system including a support structure configured to be worn by a patient, an external defibrillator configured to be coupled to the support structure and configured to defibrillate the patient while the support structure is worn by the patient, a motion sensor coupled to the support structure, and a timer, the method comprising:
defibrillating the patient while the support structure is worn by the patient;
generating, by the motion sensor, motion event data;
determining a duration of an inert period during which a motion statistic of the motion event data is less than a motion threshold;
determining whether the duration of the inert period exceeds an inert threshold; and
in response to a determination that the duration of the inert period exceeded the inert threshold, causing the output device to output a human-perceptible alert.

### Claim 14 (depends on 13)

The method of claim 13, in which
the human-perceptible alert is an audible alert.

### Claim 15 (depends on 13)

The method of claim 13, in which
the WCD system further includes a communications module, and further comprising:
communicating, via the communications module through a network, to a recipient alert event data about the duration of the inert period exceeding the inert threshold, and
in which the output device alerts the recipient.

### Claim 16 (depends on 15)

The method of claim 15, in which
the alert event data includes at least one of the motion statistic, the duration of the inert period, or the event that the duration of the inert period exceeds the inert threshold.

### Claim 17 (depends on 13)

The method of claim 13, further comprising:
receiving an inert threshold adjust input; and
adjusting the inert threshold to a new value responsive to the received inert threshold adjust input.

### Claim 18 (depends on 13)

The method of claim 13, in which
the duration of the inert period is determined as starting from a first moment, and
further comprising:
receiving a snooze input; and
resetting the first moment to a new value responsive to the received snooze input.

### Claim 19 (depends on 13)

The method of claim 13, further comprising:
receiving a Snooze-OFF input, and
in which the output device is not caused to output the human-perceptible alert responsive to the received Snooze-OFF input even in response to the duration of the inert period exceeding the inert threshold.

### Claim 20

A wearable cardiac defibrillator (WCD) system comprising:
a non-transitory computer-readable storage medium storing one or more programs which, when processed by at least one processor of the WCD system, the WCD system including a support structure configured to be worn by a patient, an external defibrillator coupled to the support structure, a motion sensor coupled to the support structure, and a timer coupled to the support structure, the WCD system performs operations comprising:
defibrillating the patient while the support structure is worn by the patient;
generating, by the motion sensor, motion event data;
determining a duration of an inert period during which a motion statistic of the motion event data is less than a motion threshold;
determining whether the duration of the inert period exceeds an inert threshold; and
in response to a determination that the duration of the inert period exceeded the inert threshold, causing the output device to output a human-perceptible alert.
