## Abstract

A system comprising a remotely programmable micromonitor with a wireless sensing system-on-module (SOM), one or more sensors to detect one or more conditions in a subject by monitoring one or more parameters associated with the conditions by comparing any monitored parameter to a baseline measurement of the monitored parameter from the subject, a plurality of sensors corresponding to a monitored parameter and connected to the micromonitor to convey measurements of all monitored parameters, the sensors including at least one of a non-optical pulse wave sensor or an electrocardiogram (ECG) sensor, a communications module capable of communicating with a wireless technology, wherein the module can send an alert signal to the subject or an attending physician or a remote service center or any other subject, and one or more algorithms for monitoring conditions and/or for predicting conditions, including at least one of a fall detection or fall prediction algorithm.

## Claims

### Claim 1

A method for monitoring a physiological condition of a subject comprising:
placing a multi-sensor monitoring system on a subject, the system configured to be positioned on the subject in such a way to detect one or more conditions in the subject, the system comprising:
a micro-monitor with a wireless sensing system-on-module (SOM), the monitor being remotely programmable to detect one or more conditions in a subject by monitoring one or more remotely programmed parameters associated with the conditions and comparing any remotely programmed monitored parameter to a baseline measurement of the monitored parameter from the subject;
a plurality of sensors, each sensor corresponding to a monitored parameter and connected to the micro-monitor to convey measurements of all monitored parameters;
the sensors comprising at least a non-optical pulse wave sensor and an electrocardiogram (ECG) sensor;
a communications module configured to communicate with a wireless technology, wherein the module is configured to send an alert signal to the subject or to an attending physician, the alert being transmitted upon the monitor detecting the remotely programmed significant physiological change in the monitored parameter as compared to the baseline measurement; and
one or more algorithms for monitoring conditions and/or for predicting conditions, the algorithms including at least one of a fall detection algorithm, a fall prediction algorithm, or a blood pressure trending algorithm which uses the non-optical pulse sensor with the ECG to measure pulse transit time (PTT); and
measuring the parameters from the subject at a baseline time to establish a baseline condition for the subject for each parameter;
measuring new parameters at a time after the baseline measurement is taken to establish a new condition for the subject for each parameter;
comparing the new condition to the baseline condition; and
determining if there is a changed condition in the subject for each parameter.

### Claim 2 (depends on 1)

The method according to claim 1, wherein determining the changed condition of the subject further comprises differentiating between episodes of central and obstructive apnea.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the fall detection algorithm further comprises utilizing information from a sensor for a sensed impact and the algorithm assesses a series of physiological changes including at least a heart rate change and a startle response.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the fall prediction algorithm predicts a likelihood of the subject falling by first testing the subject with an X-Y-Z acceleration sensor while the subject is standing to generate a subject baseline state resulting in a simulated line, wherein line lengths comprise an X-Y-Z body sway, wherein a line length of the simulated line is compared to a line length of a second simulated line measured in a second testing of the subject at a later and equivalent period of time, and wherein an increasing line length with respect to the baseline state enables detection by the monitoring system of a progressive postural instability of the subject.

### Claim 5 (depends on 1)

The method according to claim 1, further comprising measuring circulation with the ECG and comparing a measurement against a measurement made from the pulse wave sensor and an additional pulse wave sensor, with one on each side of the subject's body to yield a possible difference in two PTT's with respect to an ECG “R” wave.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the system is positioned on a left side of the subject's body and to the left of the subject's nipple.

### Claim 7 (depends on 1)

The method according to claim 1, wherein each sensor further comprises a conditioning sub-module configured to be powered up or powered down remotely to conserve a battery energy.
