Abstract: A method of localizing a robot includes receiving odometry information plotting locations of the robot and sensor data of the environment about the robot. The method also includes obtaining a series of odometry information members, each including a respective odometry measurement at a respective time. The method also includes obtaining a series of sensor data members, each including a respective sensor measurement at the respective time. The method also includes, for each sensor data member of the series of sensor data members, (i) determining a localization of the robot at the respective time based on the respective sensor data, and (ii) determining an offset of the localization relative to the odometry measurement at the respective time. The method also includes determining whether a variance of the offsets determined for the localizations exceeds a threshold variance. When the variance among the offsets exceeds the threshold variance, a signal is generated.

Abstract: A variety of applications can include an apparatus having a memory device including digit lines isolated from each other by filling an area directly under the digit line with a dielectric material. The dielectric material can be any insulating material such as oxides or nitrides. The provision of the area directly under each digit line can be accomplished without etching out an entire layer of epitaxially grown regions for the memory cells vertically stacked in a three-dimensional array. In a three-dimensional DRAM, metal plates for capacitors can be isolated in a manner similar to the isolation of digit lines. Such processing can be scalable, which may allow for a three-dimensional DRAM to have hundreds memory cell tiers.
