A communication device is disclosed having a first housing member (15) and a second housing member (20), each with an inner surface. The housing members are rotatably coupled together so that the inner surface of the first housing member is biased towards the inner surface of the second housing member. Each housing member includes an electronic circuit portion that is also coupled together. In addition, the mass of the first housing member is substantially equivalent to the mass of the second housing member so that when the communication device is attached to an object it remains balanced about the , object.

Why it's free to use
- Filed February 7, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 7, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 7, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
