In order to obtain the exact time delay of pulses in the surface acoustic wave (SAW) based radio frequency identification (RFID) at unknown temperature, we propose a method for obtaining a high phase ambiguity resolution by measuring group delays and constructing some restriction on the exact positions of reflectors. To define the restriction parameters for(More)
Flexible pins eliminate the need for straddle mounting, and therefore enable the maximum possible number of planets to be used for any particular epicyclic ratio of power transmission systems. Having more planet gears will significantly increase the input torque density. In this type of design, the pin stiffness and position tolerances are important(More)
