The limited and inconvenient functionality of conventional light switches is out pace with current advancements in wireless sensors. A chipless RFID switch (CLS) that passive, battery-free relocatable maintains the convenience having physical buttons for controlling lightbulbs or other electrical devices introduced. These characteristics have been achieved by attaching single-pole-single-throug...

We have developed an intelligent single switch scanning interface and wheelchair navigation assistance system, called ISSWN, to improve driving safety, comfort, and efficiency for individuals who rely on single switch scanning as a control method. ISSWN combines a standard powered wheelchair with a laser rangefinder, a single switch scanning interface and a computer. It provides the user with c...

In practice, almost all control systems in use today implement some form of linear control. However, there are many tasks for which conventional control engineering methods are not directly applicable because there is not enough information about how the system should be controlled (i.e. reinforcement learning problems). In this paper, we explore an approach to such problems that evolves fast-w...

This study reports findings from the administration of a social problem-solving training (SPST) intervention to juvenile detainees in the Connecticut Youth Detainee Program. SPST is a cognitive behavioral intervention that teaches children and youth how to more effectively cope with interpersonal stress and conflict. In the current study, we tested whether SPST could decrease depressive symptom...

Approved for public release; distribution is unlimited. Abstract: An ultra low power 180-degree , 1-bit phase shifter has been designed using Agilent's Advanced Design Software (ADS) co-simulation. Silicon-on-Insulator (SOI). MOSFETs were used as the switching elements because of their low current draw and low capacitance. A 1-bit 0, 180-degree phase shift has been realized with only two MOSFET...

This paper presents a high step-down tranformerless single-stage single-switch ac/dc converter suitable for universal line applications (90–270 Vr m s ). The topology integrates a buck-type power-factor correction (PFC) cell with a buck–boost dc/dc cell and part of the input power is coupled to the output directly after the first power processing. With this direct power transfer feature and sha...
