Novel system for bite-force sensing and monitoring based on magnetic eear field communication

Intraoral devices for bite-force sensing have several applications in odontology and maxillofacial surgery, as bite-force measurements provide additional information to help understand the characteristics of bruxism disorders and can also be of help for the evaluation of post-surgical evolution and for comparison of alternative treatments. A new system for measuring human bite forces is proposed in this work. This system has future applications for the monitoring of bruxism events and as a complement for its conventional diagnosis. Bruxism is a pathology consisting of grinding or tight clenching of the upper and lower teeth, which leads to several problems such as lesions to the teeth, headaches, orofacial pain and important disorders of the temporomandibular joint. The prototype uses a magnetic field communication scheme similar to low-frequency radio frequency identification (RFID) technology (NFC). The reader generates a low-frequency magnetic field that is used as the information carrier and powers the sensor. The system is notable because it uses an intra-mouth passive sensor and an external interrogator, which remotely records and processes information regarding a patient?s dental activity. This permits a quantitative assessment of bite-force, without requiring intra-mouth batteries, and can provide supplementary information to polysomnographic recordings, current most adequate early diagnostic method, so as to initiate corrective actions before irreversible dental wear appears. In addition to describing the system?s operational principles and the manufacture of personalized prototypes, this report will also demonstrate the feasibility of the system and results from the first in vitro and in vivo trials.

The fragile ‘reset’. The balance sheet and the prospects for changes in Russian-US relations. OSW Point of View (Policy Brief), April 2011

The ‘reset’ policy proposed by the USA has brought Russia a number of geopolitical, prestigious and economic benefits. The most important of those are: the resumption of arms control, the USA’s withdrawal from plans to locate elements of its strategic missile defence system in Poland and the Czech Republic, and the entry into force of the so-called 123 Agreement. In response, Russia has assisted the United States in resolving the Iranian crisis, and offered help with the Afghanistan operation, covering the transit of supplies and supporting the Afghan government. Moscow has also eased up on its anti-American rhetoric. The changes which have taken place in Russian-US relations are not durable. The two parties have not resolved their major disputes (for example, regarding missile defence), and any differences are hushed up for tactical reasons.

A new balance of power in the Council? Yes, but not yet… CEPS Commentary, 19 December 2014

On the 1st of November, the double majority system established by the Lisbon Treaty for qualified majority voting (QMV) in the Council entered into force. The shift in the balance of power, however, will not be effective before April 2017, given the possibility for member states to invoke the Nice rules until that date. While acknowledging that the new voting system in the Council promises to do away with the difficult negotiations of the past among member states to reallocate voting weights, this commentary finds that it is questionable whether it will achieve its ultimate aim to substantially improve democratic legitimacy and efficiency.
