Improving the Tamper-Aware Odometer Concept by Enhancing Dynamic Stress Operation

IEEE International Reliability Physics Symposium, 2023
On-chip degradation monitors have recently gained significant relevance because they can provide real-time estimations of IC reliability by exploiting the fundamental physics of BTI and HCD circuit degradation. Moreover, this type of degradation monitors

Finite $\beta$-expansion and odometers

Tsukuba Journal of Mathematics, 2021
The authors define the odometer for greedy and quasi-greedy \(\beta\)-expansions by the action of adding \(1/\beta\) modulo 1, where the image of a quasi-greedy expansion is quasi-greedy and the image of a finite expansion is greedy. These odometers are different from those considered in [\textit{G. Barat} and \textit{P.

A Novel UWB/IMU/Odometer-Based Robot Localization System in LOS/NLOS Mixed Environments

IEEE Transactions on Instrumentation and Measurement
The accuracy of existing ultra-wideband (UWB) range-based indoor localization methods is generally degraded due to the non-line-of-sight (NLOS) situations where a serve bias in UWB range measurements is unavoidable.

UWB–IMU–Odometer Fusion for Simultaneous Calibration and Localization

IEEE Internet of Things Journal
The location accuracy of fixed anchors plays a pivotal role in ultrawideband (UWB) positioning. However, existing calibration methods for calculating the anchor positions require anchor-to-anchor communication or known initial values for anchor locations.
