How far can a stack of n identical blocks be made to hang over the edge of a table? The question has a long history and the answer was widely believed to be of order log n. Recently, Paterson and Zwick constructed n-block stacks with overhangs of order n1/3, exponentially better than previously thought possible. We show here that order n1/3 is indeed best possible, resolving the long-standing overhang problem up to a constant factor.
The Rotary Magnetic Position Sensor product family detects the absolute angular orientation of an on-axis 2-pole magnet rotating over the center of the IC. The absolute angular position can be displayed on different outputs as PWM, ABI, UVW or directly read through the interface. According to the application’s requirements different resolutions from 8-bit up to 14-bit are available. This technology can be employed in high accuracy angle position detection, high speed rotation systems and motor control (BLDC motors). All Rotary Magnetic Position Sensors can replace both absolute and incremental optical sensors, other magnetic and inductive technologies, potentiometers and magnetic switches.
