Patent number: 10050419Abstract: A corona polarization (also denoted “poling”) process and associated apparatus polarizes a ferroelectric polymer thin film while monitoring and evaluating a substrate current whose magnitude, slope and noise profile (Barkhausen noise) varies in accordance with phase transformation processes of crystallites within the film and, thereby, provides an indication of the polarization status. The electric current flowing through the microstructures of the thin film can be modeled by an equivalent circuit, within which electrical charges stored in the respective microstructures are denoted by a plurality of discrete components (e.g., capacitors). Alternatively, the process can be modeled in terms of a hysteresis loop of polarization vs. electric field, corresponding to the availability of recombination sites on the thin-film surface.Type: GrantFiled: October 25, 2016Date of Patent: August 14, 2018Assignee: Areesys Technologies, Inc.Inventors: Kai-An Wang, Efrain A.

Publication number: 20160213976Abstract: An intelligent treadmill is described with modifications to existing treadmills, and associated methodology. The invention allows the conveyor belt automatically keeps track of and fixes the user's position dynamically with respect to a stationery reference point of the treadmill by adjusting its own speed free hands. Two position measurement techniques and their corresponding belt speed control algorithms are described. Other features of the invention allow users to perceive in real time how their surroundings would be changing by means of video, incline of platform, fan speed, sound and illumination as if they were in fact running in the natural environment. Real time positions of the runner and his partners on other treadmills with respect to a chosen track are displayed. The invention also utilizes a vectored controlled 2/3-phase AC induction motor or a BLDC motor to drive the conveyor belt for energy efficiency and fast response.Type: ApplicationFiled: January 22, 2015Publication date: July 28, 2016Inventors: Albert Ting-pat So, Jackson Ping-kuen Chack, Kin Wa Yee
