First Claim
1. A method for automatically determining the status of a wearable sensor device, the method comprising:
- affixing the sensor device to a user, the sensor including at least one accelerometer,generating, by the at least one accelerometer of the sensor device, acceleration data indicating an acceleration of the sensor device in at least one axis,determining, by a processor, acceleration-based biometric data regarding the user based at least on the acceleration data generated by the at least one accelerometer, the acceleration-based biometric data including at least one of acceleration-based respiratory data, acceleration-based cardiac data, or acceleration-based body movement data,comparing, by the processor, (a) the acceleration-based biometric data of the user to (b) reference biometric data stored in a data storage device associated with the processor,identifying, by the processor, based on the comparison of the acceleration-based biometric data of the user with the reference biometric data, a sensor device attachment condition associated with the sensor device being not properly affixed to the user, andin response to identifying the sensor device attachment condition, automatically outputting a human-perceptible alert notification via a display or other output device.

Abstract
A system for monitoring medical conditions including pressure ulcers, pressure-induced ischemia and related medical conditions comprises at least one sensor adapted to detect one or more patient characteristic including at least position, orientation, temperature, acceleration, moisture, resistance, stress, heart rate, respiration rate, and blood oxygenation, a host for processing the data received from the sensors together with historical patient data to develop an assessment of patient condition and suggested course of treatment. In some embodiments, the system can further include a support surface having one or more sensors incorporated therein either in addition to sensors affixed to the patient or as an alternative thereof. The support surface is, in some embodiments, capable of responding to commands from the host for assisting in implementing a course of action for patient treatment. The sensor can include bi-axial or tri-axial accelerometers, as well as resistive, inductive, capacitive, magnetic and other sensing devices, depending on whether the sensor is located on the patient or the support surface, and for what purpose.

13. A system, comprising:
-
a wearable sensor device configured to be affixed to a person or to an article worn by the person; at least one accelerometer provided in the wearable sensor device and configured to generate acceleration data indicating accelerations of the sensor device in at least one direction; a processor communicatively coupled to the at least one accelerometer; and a data storage device associated with the processor and storing reference biometric data; wherein the processor is configured to; determine acceleration-based biometric data regarding the user based at least on acceleration data received from the at least one accelerometer, the acceleration-based biometric data including at least one of acceleration-based respiratory data, acceleration-based cardiac data, or acceleration-based body movement data; compare the acceleration-based biometric data of the user to the reference biometric data stored in the data storage device; identify, based on the comparison of the acceleration-based biometric data of the user with the reference biometric data, a sensor device attachment condition associated with the sensor device being not properly affixed to the user, and in response to identifying the sensor device attachment condition, automatically cause a human-perceptible alert notification to be output via a display or other output device. - View Dependent Claims (14, 15, 16, 17, 18, 19)
