Publication number: 20240390055Abstract: A medical system and method for estimating a treatment region for a medical treatment device is provided. The system includes a memory; a processor coupled to the memory; and a treatment control module stored in the memory and executable by the processor. The treatment control module generates an estimated treatment region which is an estimate of a treatment region which would have been derived as a result of a numerical model analysis such as a finite element analysis. Advantageously, the estimated treatment region is generated using a fraction of the time it takes to generate the region using the numerical model analysis.Type: ApplicationFiled: August 7, 2024Publication date: November 28, 2024Applicants: AngioDynamics, Inc., Virginia Polytechnic Institute and State UniversityInventors: Robert M.

Patent number: 9276480Abstract: Pulse width modulation is provided for controlling a resonant power converter, particularly for dimming of light emitting diode arrays without loss of efficiency. Dynamic oscillation due to the beginning of a pulse width modulated pulse burst is limited by shortening of the first and/or last pulse of a pulse bust such that the first pulse of a subsequent pulse burst close to or to connect with a full load steady-state voltage/current trajectory of the power converter. Pulse shortening made be made substantially exact to virtually eliminate dynamic oscillation but substantial reduction in dynamic oscillation is provided if inexact or even performed randomly.Type: GrantFiled: December 24, 2013Date of Patent: March 1, 2016Assignee: Virginia Polytechnic Institute and State UniversityInventors: Weiyi Feng, Fred C.
