Gyroscope Drift Error Analysis in the Position-Independent Navigation Algorithm of a stable platform Inertial System

This paper deals with analyzing gyroscope drift error in the position-independent navigation algorithm of a stable platform inertial system. Most of the stable platform navigation algorithms proposed in the literature have drawbacks of estimating position rates for alignment commands. Not only the estimating position rates are the basic source of position errors, but they also make the alignmen...

Position and Orientation Tracking System (POTS)

Fast Color-Based Object Recognition Independent of Position and Orientation

Small mobile robots typically have little on-board processing power for time-consuming vision algorithms. Here we show how they can quickly extract very dense yet highly useful information from color images. A single pass through all pixels of an image serves to segment it into color-dependent regions and to compactly represent it by a short list of the average hues, saturations and color inten...

Towards a position and orientation independent approach for pervasive observation of user direction with mobile phones

This paper presents a novel approach for mobile phone centric observation of a user’s facing direction, relying solely on built-in accelerometer and magnetometer. Our approach achieves greater accuracy and independence by an automatic detection of the wearing position of the mobile device on the user’s body and subsequent selection of an optimum strategy for estimating the user direction. We re...

Position- and orientation-independent activity of the Schizosaccharomyces pombe meiotic recombination hot spot M26.

The activity of the M26 meiotic recombination hot spot of Schizosaccharomyces pombe depends on the presence of the heptamer 5'-ATGACGT-3'. Transplacement of DNA fragments containing the ade6-M26 gene to other chromosomal loci has previously demonstrated that the heptamer functions in some, but not all, transplacements, suggesting that hot spot activity depends on chromosomal context. In this st...
