Three-coil inductive power transfer (IPT) charging system can not only achieve inherent constant current (CC) to voltage (CV) transition but also tolerate load open-circuit. However, due the cross-coupling between auxiliary coil and receiver coil, output in CV mode may deviate from significantly, which makes design freedom of three-coil coupler low. By replacing with a transformer, an improved ...

gap resonator coil; B) a loop-gap resonator implantable coil coated with PDMS; and C) a surface coil. Each coil contains two tuning capacitors and a decoupling circuit that includes a hand-wound inductor and Schottky anti-parallel diodes. Development of a Receive-Only Inductively-Coupled RF Coil System to Enhance H NMR Localized Spectroscopy to Monitor an Implantable Bioartificial Construct at ...

The investigation on the constant current (CC)/constant voltage (CV) charging for electric vehicle wireless power transfer (WPT) system has been widely conducted. However, CC/CV performance under misalignment cases scarcely studied especially multi-coil WPT system. resonant tank compensation methodology exciter-quadrature-repeaters (EQR) transmitter-based is to achieve high factor with low leak...

Introduction Before we embark on the topic of array coils designs, the reader is referred to a historic paper by Hoult [1] that provides a detailed overview and discussion on the NMR receiver. Most of today’s RF receive coil designs are based upon the phased array coil technology proposed by Roemer et al. in 1990 [2], and its application to volume imaging was discussed by Hayes et al. in 1991 [...

OBJECTIVES The purpose of this study was to compare defibrillation thresholds with lead systems consisting of an active left pectoral electrode and either single or dual transvenous coils. BACKGROUND Lead systems that include an active pectoral pulse generator reduce defibrillation thresholds and permit transvenous defibrillation in nearly all patients. A further improvement in defibrillation...

The article presents a detection system with spider web coil-based wireless charging. Commonly available metal detectors are sold as handheld systems, which enable only progressive, lengthy, time-consuming search. Importantly, part of the investigated area can thus be easily missed, and probability that object will not found increases substantially. This problem, however, is eliminable via auto...

BACKGROUND Publication bias and/or true heterogeneity can skew aggregate impressions from scientific literature. To better determine aggregate measures for unruptured intracranial aneurysm (UIA) treatment, we analyzed adverse outcome rates of surgical clipping and endovascular coil embolization. METHODS Two independent reviewers searched MEDLINE for studies publishing adverse outcome rates fo...

Increasing evidence demonstrates the importance of long coiled-coil proteins for the spatial organization of cellular processes. Although several protein classes with long coiled-coil domains have been studied in animals and yeast, our knowledge about plant long coiled-coil proteins is very limited. The repeat nature of the coiled-coil sequence motif often prevents the simple identification of ...
