Publication number: 20150176989Abstract: The embodiments disclosed are directed to systems and methods for determining the inclination of a surface beneath a vehicle. In some embodiments, a method uses an accelerometer to determine a final surface inclination value. The final surface inclination value can then be used to compensate for the acceleration of the vehicle caused by gravity. The method includes receiving accelerometer values from the accelerometer. The method also includes determining surface inclination values based on the accelerometer values. The method further includes storing the surface inclination values. And the method includes applying a digital filter to the stored surface inclination values to determine a final surface inclination value.Type: ApplicationFiled: December 23, 2013Publication date: June 25, 2015Applicant: HTI IP, LLCInventors: Stephen Christopher Welch, JAMES RONALD BARFIELD, JR.

Publication number: 20150145662Abstract: A personal emergency response (PER) device may include an audio sensor that is used to enhance the operation of the PER device. The audio sensor may obtain audio data that can be used to verify whether a fall event that is detected by the PER device is a false positive signal and/or enhance the reliability of a detected fall event. In some implementations, the audio data may be used in the detection of vehicle crashes in which a user of the PER device is involved.Type: ApplicationFiled: November 26, 2013Publication date: May 28, 2015Applicant: HTI IP, L.L.C.Inventors: James Ronald Barfield, Jr, Stephen Christopher Welch

Publication number: 20150061863Abstract: Techniques described herein relate to the classification of fall events for PER (personal emergency response) devices. In one implementation, data relating to acceleration events that occurred at the PER devices may be received. The data relating to the acceleration events may be associated with indications of whether the acceleration events correspond to fall events of users of the PER devices. A classification model may be trained based on the data relating to the acceleration events and the indications of whether the data relating to the acceleration events corresponds to the fall events. The classification model may be transmitted to at least some of the PER devices to update a previous version of the classification model at the at least some of the PER devices.Type: ApplicationFiled: September 3, 2013Publication date: March 5, 2015Applicant: HTI IP, L.L.C.Inventors: James Ronald Barfield, JR., Stephen Christopher Welch

Publication number: 20150007632Abstract: The axes of an accelerometer, installed in a vehicle at an arbitrary orientation, may be realigned to the coordinate frame of the vehicle. In one implementation, a method may include determining, based on acceleration measurements from the accelerometer that likely corresponds to stopping, a dominant orientation of the accelerometer in relation to gravity, including calculating a first transformation angle and a second transformation angle as parameters to perform coordinate realignment of a coordinate frame of the accelerometer to a coordinate frame of the vehicle. The method may further include identifying, based on the acceleration measurements, an occurrence of acceleration events of the vehicle; determining, based on an analysis of the acceleration events, a third transformation angle; and storing the first, second, and third transformation angles.Type: ApplicationFiled: July 5, 2013Publication date: January 8, 2015Applicant: HTI IP, L.L.C.Inventors: Stephen Christopher Welch, James Ronald Barfield, JR.

Publication number: 20140214353Abstract: 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.Type: ApplicationFiled: January 21, 2014Publication date: July 31, 2014Inventors: James Ronald Barfield, Stephen Christopher Welch
