An in-line continuous feed sleeve labeling machine labels containers, such as beverage containers, in an in-line fashion maintaining the elevation of the containers during their linear transport. The in-line continuous feed sleeve labeling machine of the present invention receives bottles in flood feeder or linear fashion. A timing screw or the like properly separates, and both spatially and temporally disposes, the containers for sleeving. The timing screw propels the containers onto a pedestal system. The pedestals of the pedestal system maintain their horizontal nature due to offset pivotable attachments to the track system upon which they travel. In coordinated fashion with the travel of the pedestal system, iris carriers carrying sleeves upon articulating radial arms descend upon the bottles. Once the label sleeve has reached the appropriate point (generally adjacent to the central portion of the bottle), the iris carrier allows the label sleeve to engage the central portion of the bottle. Frictional attachment or otherwise allows the finger rods of the iris carrier to pull away from the sleeve as the iris carrier continues to descend down towards the pedestal. The sleeve then becomes attached to or engaged by the bottle until the finger rods of the iris carrier free themselves from the sleeve label. A container stabilizer may provide lateral bottle support and aid the ensleevement process. The finger rods then dilate to better disengage the bottle as the iris carrier ascends up and away from the bottle. The bottle is then transported to an exit conveyor having been properly sleeved, while the iris carrier returns to transport another sleeve.

Cellular phones are becoming more common and popular amongst all sectors of the population for business and private conversations, including many children, with about a Billion users worldwide, and about 300,000 new joiners each day. There is much concern and there is already some accumulating evidence that the Microwave emission transmitted by the cellular antenna that is held close to user's head may have deleterious effects on the user, such as for example brain or eye cancer, and possibly even more so for children. One of the most common ways to try to avoid these problems has been the usage of personal earphones with microphone, but on Apr. 4, 2000 it was published worldwide that a research conducted by the “Which?” consumer Magazine in Britain found that in fact the earphone and its cable can act as an Antenna and also expose the user to the microwave radiation. The present invention solves the above problem in using earphones with cellular phones by a reverse and more sophisticated solution than short range wireless earphones, and also solves the problem that many people don't like using headsets at all. Another important variation is the use of short range low energy pulse-based carrier-free wireless communication (preferably UWB) between the two parts of the phone and/or between the phone and a headset and/or between the headset and the proxy.
