Abstract
Systems and methods disclosed herein may be useful for use in landing identification. In this regard, a method is provided comprising receiving pulse information over a first time period, wherein the pulse information is indicative of an angular distance traveled by a first wheel, comparing the pulse information to a threshold value, and determining a likelihood of a landing event based upon the comparison. In various embodiments, a system is provided comprising a monstable multivibrator in electrical communication with a metal-oxide-semiconductor field-effect transistor (MOSFET), a resistor-capacitor network in electrical communication with the MOSFET, and a comparator that receives a voltage from the resistor-capacitor network and a reference voltage.
Claims7
A method for landing identification comprising:
- triggering a monstable multivibrator in response to a conditioned wheel angular displacement signal;
- sinking current, using a metal-oxide-semiconductor field-effect transistor (MOSFET), in response to the triggering;
- creating an average voltage at a node from pulsed voltage at a drain of the MOSFET;
- comparing, using a comparator, the average voltage to a reference voltage;
- and
- determining a likelihood of a landing event based upon the comparison.
