A Single-Stage Regulating Voltage-Doubling Rectifier for Wireless Power Transfer

In this letter, a 6.78-MHz single-stage regulating voltage-doubling rectifier is presented for biomedical wireless power transfer (WPT) applications. Derived from a full-wave voltage doubler, a theoretical voltage conversion ratio (VCR) of 2 can be achieved, which benefits the end-to-end voltage gain of a biomedical WPT system with varying...

A Dynamically Reconfigurable Recursive Switched-Capacitor DC-DC Converter with Adaptive Load Ability Enhancement

Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc-dc converters, based on several basic 2:1 converters, are widely used for on-chip power supplies due to their flexible VCRs for higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more 2:1 converters unused for some VCRs,...

Video-Based Two-Dimensional Kinematic Analysis for the Evaluation of Lower Limb Function in Patellar Tendinopathy

Patellar tendinopathy (PT) is a common manifestation in jumping sports characterized by pain and a reduced load bearing capacity. The exact cause of PT has not been determined, which makes it difficult to prevent and treat. A stiffer landing technique might be a risk-factor for PT. Retraining of the landing technique into a less stiffer...

Shadow Internet: A censorship-free communication infrastructure

Due to the rise of smartphone technology, numerous citizens carry Internet-enabled recording equipment with them at all times. Should atrocities be committed by the the government, they would have a hard time to cover-up the truth without blocking the Internet. Governments have demonstrated their ability to restrict access to the Internet during...
