A Fully Integrated Auto-Calibrated SuperRegenerative Receiver
2006 IEEE International Solid State Circuits Conference - Digest of Technical Papers, 2006A fully integrated super-regenerative receiver in 0.13mum CMOS with on-chip quench generation is described. Auto-calibration improves the selectivity of a Q-enhanced filter and the sensitivity of super-regeneration. The prototype consumes 2.8mW, or 5.6nJ per received bit, at 500kb/s, and has a turn-on time of 83.6mus, a channel spacing of 10MHz, and a ...

Auto-calibration tests for discrete finite regression functions
European Actuarial JournalAuto-calibration is an important property of regression functions for actuarial applications. Comparably little is known about statistical testing of auto-calibration. Denuit et al.~(2024) recently published a test with an asymptotic distribution that is

Auto-calibrating analog timer for on-chip testing
International Test Conference 1999. Proceedings (IEEE Cat. No.99CH37034), 2003A practical approach for generating precise and slow analog ramps to be used for time-domain analog testing and for monotonicity and histogram test of ADCs is presented. The technique uses a discrete-time adaptive scheme to calibrate the ramp generator. Two implementations of the approach are proposed: one is entirely single-ended and the second uses a

Camera auto-calibration from articulated motion
2007 IEEE Conference on Advanced Video and Signal Based Surveillance, 2007This paper presents a novel auto-calibration method from unconstrained human body motion. It relies on the underlying biomechanical constraints associated with human bipedal locomotion. By analysing positions of key points during a sequence, our technique is able to detect frames where the human body adopts a particular posture which ensures the ...

Auto-Calibration Around-View Monitoring System
2013 IEEE 78th Vehicular Technology Conference (VTC Fall), 2013This work is to establish an auto-calibration around-view monitoring system to avoid the inconsistent performance from deviations of camera installation. First, a vehicle is parked at a specific area which has a special pattern on the ground. Second, the captured images from four embedded cameras are compared with the reference pattern images to obtain

A New Method for Auto-calibrated Object Tracking
2005Ubiquitous computing technologies which are cheap and easy to use are more likely to be adopted by users beyond the ubiquitous computing community. We present an ultrasonic-only tracking system that is cheap to build, self-calibrating and self-orientating, and has a convenient form factor. The system tracks low-power tags in three dimensions.

Scene Understanding for Auto-Calibration of Surveillance Cameras
2014In the last decade, several research results have presented formulations for the auto-calibration problem. Most of these have relied on the evaluation of vanishing points to extract the camera parameters. Normally vanishing points are evaluated using pedestrians or the Manhattan World assumption i.e. it is assumed that the scene is necessarily composed

Auto-Calibration of a Robotic Head
1997Visual sensor calibration represents the problem of determining the parameters of the transformation between the 3D information of the imaged object in space and the 2D observed image. Such a relationship is mandatory for 3D vision. More precisely, we have to know the location (translation) and attitude (rotation) of the visual sensor with respect to ...

Auto-calibration of Uniform Linear Array Antennas
2019 27th European Signal Processing Conference (EUSIPCO), 2019Calibration is instrumental to realize the full performance of a measurement system. In this contribution we consider the calibration of a uniformly linear array antenna where we assume each antenna element has an unknown complex gain. We present an algorithm which can be used to calibrate the array without full knowledge of the environment ...

Auto-calibrating Spherical Deconvolution Based on ODF Sparsity
2013Spherical deconvolution models the diffusion MRI signal as the convolution of a fiber orientation density function (fODF) with a single fiber response. We propose a novel calibration procedure that automatically determines this fiber response. This has three advantages: First, the user no longer needs to provide an estimate of the response.
