Filed:

Oct 24, 2008

Appl. No.:

12/258006

Inventors:

Nicholas Anderson - Bayside NY, US

Assignee:

Energy Innovative Products, LLC - Roseland NJ

International Classification:

H02P 27/00
H02P 3/18

US Classification:

318809, 318729, 318799, 318810

Abstract:

A power control system for an A. C. induction motor is disclosed, comprising a voltage/current phase difference generator for determining a difference in phase between a voltage applied to the motor and a current drawn by the motor, and for generating a phase difference signal as a function of the determined difference in phase, the voltage/current phase difference generator including an integrator, the integrator receiving the phase difference signal and generating an error signal for controlling an amount of power supplied to the motor as a function of the phase difference signal, the integrator being electrically coupled to a potentiometer, the potentiometer providing a bias signal for at least partially controlling the error signal; and a delay circuit for controlling the bias signal provided by the potentiometer so as to cause full available power to be supplied to the motor for a predetermined amount of time. The potentiometer further comprises first and second outer terminals and a center tap terminal, the center tap terminal providing the bias signal. The delay circuit controls the resistance appearing across the first outer terminal and second outer terminal of the potentiometer for the predetermined amount of time.

International Classification:

G06G 7186
H02P 736

US Classification:

318729

Abstract:

A power factor control system for an A. C. induction motor determines the difference in phase between the voltage applied to the motor and the current drawn by the motor. Based upon this difference in phase, an integrator generates an error signal. The error signal is compared with a ramp wave to derive a pulse signal which controls the voltage applied to the motor, which in turn controls the amount of current supplied to the motor, in order to reduce the power consumed by the motor. The integrator includes a dual-path feedback filter having a polarized capacitor in each path. A power supply is used to quickly provide the full operating bias voltages required by several of the components contained in the control system.

International Classification:

A61M 39/16
A61M 39/18
A61M 39/20

Abstract:

Capping and cleansing devices for capping and cleansing medical connectors, particularly luer access devices, and methods for using such articles, are described. Such articles include a cap, a compressible cleansing matrix attached to the cap, and a resilient inner body disposed in the cap such that cap can mechanically engage and disengage the resilient inner body so as to allow the cap to rotate in unison with the resilient inner body when the two components are engaged or to rotate in relation to the resilient inner body when the two components are disengaged.
