A method for determining a pose of an object in a scene by determining a set of scene features from data acquired of the scene and matching the scene features to model features to generate weighted candidate poses when the scene feature matches one of the model features, wherein the weight of the candidate pose is proportional to the model weight. One or more of the semiconductor memory devices may detect a read command and a dummy read command in response to the command signal and the chip selecting signal and generate one or more preamble signals based on a calculated preamble cycle number. The seat-lift assembly is attached to a seat linkage mechanism that includes a seat-mounting plate, a base plate coupled and a linear actuator for automating adjustment of the linkage mechanism. With this, a rear-projection screen with small wavelength dependency of diffusion characteristics can be provided utilizing only resins with general properties. Included are techniques that correct for proximity effects associated with an edge in a layout corresponding to the design layer. An example embodiment provides a memory cell that uses more than 2X logic levels to store X data bits and an error bit.
