Patent CA-2578109-C (CA)
Title: System and method for controlling total electrical power across multiple furnaces using electrode positioning
Inventor: MA THOMAS LAI WAI
IPC: F27D11/10
Filed: 2005-09-01
Granted: 2015-01-13
Abstract: A method and system for stabilizing energy consumption in multiple loads, or in single multi-phase loads. The method and system also compensates for unbalance in multi-phase loads. A central controller monitors variable reactances in the loads and identifies situations of power and/or current fluctuation and/or unbalance. It determines appropriate corrective action by the other loads/phases to compensate for the power and/or current change or unbalance due to the problematic load, and it issues control signals instructing variable reactor controllers associated with the other loads to adjust accordingly. The method and system may by applied to electric arc furnace installations. In this context, the method and system provide an electrode position controller coupled to the feed rate controller so as to predicatively anticipate the introduction of new feed material and lower the electrodes so as to prevent arc extinguishment while the variable reactors maintain predetermined power set-points. The electrode position controller may be used in place of, or in conjunction with, the variable reactance control system to take corrective action to address power and/or current changes or unbalances. The variable reactors respond orders of magnitude faster than the electrode positioning system. The system and method may be employed to maintain a predetermined level of unbalance in the system.

Abstract: An apparatus and method for the evaluation of tissue ablation is provided. The apparatus comprises a broadband (white; multiple wavelengths) light and/or laser light (single wavelength) illumination source that delivers light to the site where a lesion is being formed. Scattered light is collected from the ablated tissue and evaluated to obtain qualitative information regarding the newly formed lesion. The apparatus allows assessment of such parameters as, for example, catheter- tissue proximity, lesion formation, depth of penetration of the lesion, cross-sectional area of the lesion in the tissue, formation of char during the ablation, recognition of char from non-charred tissue, formation of coagulum around the ablation site, differentiation of coagulated from non-coagulated blood, differentiation of ablated from healthy tissue, and recognition of steam formation in the tissue for prevention of steam pop. These assessments are accomplished by measuring the intensity and spectrum of diffusely reflected light at one or more wavelengths.

Resulting in stablized high-power laser-emission-output into a single low-order fundamental transverse cavity mode and reversal of intra-cavity chirp that provides for high-speed internal modulation capable of transmitting data at around 20-Gigabits/ps.
