Abstract: A method for providing adaptive radio transmit power based on antenna pattern and elevation tilt measured through an accelerometer is provided. The method includes estimating an orientation of a wireless device using an orientation sensor integrated in or on the wireless device, and determining an adjustment factor for a transmitter of the wireless device based on the orientation. The method further includes adjusting output power of the transmitter of the wireless device based on the adjustment factor.

Abstract: The present invention relates to a high strength roller chain adapted for both high cyclic loads as well as intermittent high shock loads. The roller chain of the present invention includes a pin link plate having a cross sectional area through a center line of a pin receiving aperture greater than a pin link plate in a standard ANSI of an equivalent size roller chain. Further, the cross sectional area of the roller link plate through center line of one of the bushing-receiving openings is greater than that of a roller link plate in a standard ANSI roller link plate in an equivalent size roller chain. Further, the pin itself has a greater cross sectional area than the pin of a standard ANSI equivalent size roller chain.
