Abstract: The present disclosure relates to a system and method of detecting activity by a wheelchair user. In one aspect, a method comprises collecting motion data of a user device located on an appendage of the user; detecting, by a processor circuit, that one or more activities by the wheelchair user occurred based on the motion data; calculating, by a processor circuit, an energy expenditure by the user based the one or more activities by the wheelchair user occurred; and outputting, by a processor circuit, the energy expenditure estimation.

Abstract: A system and method for improving the accuracy of a user device when generating map/navigation information for display to a user, comprising: obtaining compass heading from a magnetometer of the user device located within a vehicle; adjusting the compass heading based on a mount angle of the user device within the vehicle; obtaining location data from a location sensor of the user device; determining if a course of the vehicle can be reliably determined from the location data; if the course of the vehicle cannot be reliably determined from the location data, determining the orientation of the vehicle using the compass heading but not the course; if the course of the vehicle can be reliably determined from the location data, calculating a course of the vehicle based on the location data and determining the orientation of the vehicle using the course; generating, by a processor, first map/navigation information using the orientation of the vehicle; and displaying, by a processor, the first map/navigation inform

Abstract: A method for performing continuous calibration of a magnetometer in a device includes during operation of a device, continually performing magnetometer measurements; continuously determining a state of the device; determining a magnetometer calibration model based on the magnetometer measurements and the state of the device; continually evaluating an accuracy of the magnetometer calibration model based the magnetometer measurements and the state of the device; and updating the magnetometer calibration model based on the evaluation of the accuracy magnetometer calibration model, the magnetometer measurements, and the state of the device.

Abstract: An array of mechanical force reduction assemblies sized and configured to independently mechanically manipulate a fractured bone region. Each assembly functions independently of the other assemblies, to apply and maintain one of the prescribed mechanical reduction forces to the fracture, to thereby mechanically reduce the fracture in a desired way. A carrier coupled to the assembly accommodates temporary attachment of an orthotic brace, residing thereon, partially or fully assembled in a region of the bone fracture. A linkage mechanism accommodates the rotational articulation of the brace in response to the application of one or more mechanical force vectors, to move the bone fracture into a desired anatomic orientation. A locking mechanism maintains the orientation of the brace to maintain the desired anatomic orientation. After release from the carrier, the brace serves in an ambulatory fashion to maintain the desired anatomic orientation after reduction and as healing occurs.
