A magnetic sensor-based tracking system, a method, and computer readable media for tracking an apparatus having a magnetic field generating device through an environment having a consistent magnetic field are provided. The magnetic sensor-based tracking system includes the apparatus having the magnetic field generating device, one or more magnetic field sensing devices, and a controller. Each of the one or more magnetic field sensing devices is configured in operation to be located within a sensible range of an expected path of the magnetic field generating device as it passes through the environment, the expected path including a plurality of regions. The controller is coupled to the one or more magnetic field sensing devices and configured in operation to utilize magnetic field sensing of the one or more magnetic field sensing devices to track the apparatus within the environment by obtaining at least one magnetic field reading from at least one of the one or more magnetic sensing devices and computing a position and an orientation of the apparatus within the environment based on at least one solution set obtained from a pre-obtained magnetic field model.

Magnetic field based tracking methods and systems

A force sensor for a tendon-actuated mechanism, the force sensor comprising: a body having a through hole for passage of a tendon of the tendon-actuated mechanism therethrough, the body configured to be connected to a part of the tendon-actuated mechanism through which the tendon passes; and a sensor provided on the body to obtain a compression force on the body from the part of the tendon-actuated mechanism through which the tendon passes.

Force sensor for tendon-actuated mechanisms

An intragastric device comprising: an inflation magnet provided within a capsule and configured to move towards a first end of a capsule during activation of the intragastric device by applying a magnetic field externally to a user after swallowing the intragastric device; a first chamber and a second chamber physically separated by a partition having a through hole; a separator connected to the inflation magnet and sealing the through hole before activation of the intragastric device, wherein activation of the intragastric device moves the separator to unseal the through hole to allow a chemical reaction between a first chemical stored in the first chamber and a second chemical stored in the second chamber; a balloon secured to the capsule and collapsed against the capsule before activation of the intragastric device; and an expandable volume configured to expand when the balloon is inflated by a gaseous product of the chemical reaction.
