PIVOT

The Lucas Free-Flex® Pivot is a frictionless, precision cross-spring bearing for use wherever limited angular rotation bearings are required for angular travel up to ±30 degrees. The pivot requires no lubrication and no maintenance, is dirt insensitive, and eliminates the inaccuracies of friction, striction, wear, radial clearances, and backlash. The pivot has a high radial and axial stiffness to maintain repeatability to ±0.000001 inch in one plane of motion, with low hysteresis, center shift, and thermal drift.

Decoder

The 68181 roaming FLEX-paging decoder allows carriers to network many paging systems and provide service to customers who want nationwide paging without disrupting service to existing local customers. The FLEX roaming chip is programmed by the carrier with all the frequencies used in a nationwide paging network. These frequencies are stored in a look-up table in the pager's memory. When a paging customer travels away from the area, the pager detects the loss of signal and searches the frequencies programmed in the table using the pager's synthesized tuner. When a paging signal is found, the pager stops searching and locks onto the new frequency.
