Abstract
A magnetometer-based monitoring system comprising a magnet integrated with an object whose disposition is to be monitored, a first magnetometer secured in proximity to the object, and a second magnetometer secured at a fixed distance from the first magnetometer in proximity to the object. The monitoring system further comprising a processor to receive data from the first magnetometer and the second magnetometer, and calculate a measurement vector to determine the disposition of the object.
Claims19
A system comprising:
- a logging device including:
- a magnetometer designed to be in close proximity to a small magnet in an eye patch, the magnetometer to monitor a magnetic field, generated by the small magnet, earth, and proximate magnetic devices;
- a memory to store data from the magnetometer;
- and
- a communication link to obtain the data from the memory, the data processed to show a pattern of wearing and not-wearing the eye patch, to monitor compliance with a medical prescription.
An eye patch for improved monitoring of compliance with a medical protocol, the eye patch comprising:
- a covering portion to substantially cover one eye;
- and
- a magnet positioned on a side of the eye patch, such that when glasses are worn, a magnetometer positioned on the glasses can detect a magnetic field of the small magnet, the presence of the magnet used to determine the compliance with the medical protocol.
A magnetometer-based monitoring system comprising:
- a magnet integrated with an object whose disposition is to be monitored, wherein the object is an eye patch worn by a user;
- a first magnetometer located in proximity to the object to detect a magnetic field of the magnet;
- a second magnetometer located at a fixed distance from the first magnetometer in proximity to the object to detect the magnetic field of the magnet;
- a processor to receive data from the first magnetometer and the second magnetometer, and calculate a measurement difference 3-vector to determine the disposition of the object based on data from the first magnetometer and the second magnetometer and unknown rotations of the object in Earth's magnetic field.
