20140172351 | METHOD AND SYSTEM FOR DETERMINING THE HEIGHT OF A DEVICE ABOVE GROUND - A device updates a value representing its current height above ground when it detects a height change. The device uses the slope calculated from collected barometric pressure data samples to calculate height change during a period when the value of the slope exceeds a predetermined value. The device also analyzes a predetermined number of barometric pressure sensor data samples preceding and succeeding a height change indicated by the slope change. The device performs an evaluation, i.e., determining the difference between an average of the preceding and succeeding samples, to determine a height change. The device may select either the slope-of-the-curve-during-the-height-change-period method or the difference-between-the-averages method based on meeting a criterion. The processor de-energizes a GPS circuit, height determination method, and sets the height above ground to zero if it detects movement. Placing the device on a charger resets the device's height value to the charger height above ground. | 06-19-2014 |

20130054180 | METHOD AND SYSTEM FOR DETECTING A FALL BASED ON COMPARING DATA TO CRITERIA DERIVED FROM MULTIPLE FALL DATA SETS - A device monitors sensor data generated by movement of a wearer and determines whether the data indicates a fall. The device may include accelerometers, barometer(s), and sensors that detect, light, sound, temperature, magnetic and electric fields, strain-force on the device, and other environmental conditions. A processor determines whether the data meets a first criterion for a parameter (i.e., exceeding, an acceleration or barometric pressure maximum threshold). The first criterion corresponds to a first set of known-fall event data sets. If the first criterion is met, the processor generates a full indication. If the data does not meet the first criterion, the processor compares the data to a second criterion for the same, or different, parameter. If the second parameter is met, further processing confirms a fall determination by comparing the data to other criteria corresponding to known-fall event data sets that differ from the first set. | 02-28-2013 |
20130197856 | Method and system for discerning a false positive in a fall detection signal - Methods reduce the likelihood of an MPERS device falsely reporting a high acceleration event as a fall impact. The device stores acceleration data acquired before the high acceleration and afterward. If a number of samples of magnitude values from accelerometer sensors in the device acquired during as interval before the high acceleration that approach 0G exceeds a predetermined number, the high acceleration is deemed from a non-fall. Acceleration sensors can also indicate an orientation change before/after the high acceleration, and a barometric pressure sensor can do the same, to further characterize an event as a non-fall. A method compares current event data to composite data sets that have been determined from a plurality of empirically derived data sets of fall and non-fall events. High correlations can indicate falls, or non-falls, respectively. Further statistical analysis of data acquired after an event reduces the likelihood of falsely indicating a fall. | 08-01-2013 |
20140122012 | METHOD AND SYSTEM FOR DETERMINING WHETHER TO RESET A HEIGHT IN A HEIGHT DETERMINING DEVICE BASED ON THE OCCURRENCE OF STEPS - A filter processes acceleration magnitude signals from an accelerometer device to output spectral content related to walking and running. A device containing the accelerometer determines steps by qualitatively analyzing the processed acceleration signals to determine whether increased acceleration magnitude results from a step impact from running or walking activity. The device may analyze the acceleration signals to determine crossings of an axis at zero magnitude, which crossings typically correspond to a person's foot impacting the ground, and may analyze the period, between the zero crossings. The step count can indicate whether the device, in a height determination mode, is moving in a vehicle; if analysis of accelerometer signals indicates no stepping or running, but another circuit of the device indicates rapid movement, the device assumes it is moving in a vehicle, and resets a height above ground value to zero upon determining resumption of walking or running activity. | 05-01-2014 |

20140324459 | AUTOMATIC HEALTH MONITORING ALERTS - A device may receive information that identifies a first health metric value associated with a user and a first time, and may receive information that identifies a second health metric value associated with the user and a second time that is different from the first time. The device may receive medical record information associated with the user and a third time, where the medical record information is different from the first health metric value and the second health metric value. The device may infer a relationship between the first health metric value, the second health metric value, and the medical record information, based on the first time, the second time, and the third time. The device may provide an indication of the inferred relationship. | 10-30-2014 |

20140214353 | METHOD TO DETERMINE A PRESSURE NOISE METRIC FOR FALL DETECTION SYSTEMS - A wearable fall-detection device has a variety of sensors, including a pressure sensor, that provide signals for sampling environmental conditions acting on the device. An average of pressure data samples is used to determine a resultant that may indicate an amount of noise in a pressure data signal, and statistical analysis of the noise and the pressure signal average may be used to determine a confidence estimate value that indicates a level of confidence in the amount of noise that a pressure signal is subject to, or includes. The confidence estimate and known fall data, such as change in pressure between a person standing and lying, can create a threshold function that may adapt according to sampled data thus providing a customizable (either statically or dynamically) threshold function for comparing sensor data against rather than comparing data with just a linear threshold function. | 07-31-2014 |
