The invention relates to a device (100) for sealing a container having a neck, said device comprising: a deformable portion (1) intended to be at least partially arranged inside the neck of the container so as to seal it in a leak tight manner, said portion being capable of deforming elastically when inserted into the neck, said portion comprising a first end intended to be oriented towards the inside of the container, and a radiofrequency identification tag (11), said device being characterised in that it comprises at least one piezoelectric component (10) electrically connected to the tag (11) and arranged inside said deformable portion (1), within a blind recess on the first end side, generating an electric voltage caused by expansion of the deformable portion containing the piezoelectric component when said deformable portion is removed from the neck, said electric voltage being capable of causing a change of state of the radiofrequency identification tag.

Embodiments of the present invention provide devices (tags), systems, and methods to determine structural integrity and other states of orthodontic-elements, such as orthodontic-brackets, orthodontic-archwires, orthodontic-expanders, orthodontic-elastic-bands, and orthodontic-power-chains, to name a few, in a non-invasive and contactless way, with respect to monitoring; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized backscatter-tags with sensors are implanted in or attached to such orthodontic-elements. Such arrangements may permit monitoring of forces acting on teeth by various orthodontic-elements. Using backscatter imaging technology, the structural integrity and other states of the orthodontic-elements may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized backscatter-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the orthodontic-elements.

A sensing system generates location signals indicative of where an electrically-powered, mobile device is in a venue. A control system determines that the mobile device is at rest when the location signals are substantially the same for a predetermined period of time, processes the location signals to determine an accurate, current location of the mobile device in the venue when the mobile device is determined to be at rest, and controls the mobile device when determined to be at rest to operate in a low power mode in which the average electrical power consumption of the mobile device is reduced.
