Patent number: 6320378Abstract: Apparatus and method for generating and displaying undistorted images of a field of view containing undesirable motion and/or time varying magnetic field inhomogeneities, uses a time series of magnetic resonance (MR) image signals, corresponding to a time series of MR images, generated by a single-shot imaging technique without shot-to-shot phase encoding. Signals are stored and analyzed to identify missing and/or deteriorated images (including image portions, image lines or image line segments). Identified missing and/or deteriorated images are compensated for by replacement, repair or otherwise. MR image signals representative of a specified time series are selected. Then, selected signals of corresponding portions of the field of view are averaged. The invention may be used to present: a continuously updated time series of images; a time series of images with only a specified portions of the image updated in each display; or an entire time series of images re-created in any desired sequence.Type: GrantFiled: March 30, 2001Date of Patent: November 20, 2001Assignee: Brigham & Women's HospitalInventors: Stephan E.

Patent number: 6316918Abstract: An integrated system for comprehensive control of an electric power generation system utilizes state machine control having particularly defined control states and permitted control state transitions. In this way, accurate, dependable and safe control of the electric power generation system is provided. Several of these control states may be utilized in conjunction with a utility outage ride-through technique that compensates for a utility outage by predictably controlling the system to bring the system off-line and to bring the system back on-line when the utility returns. Furthermore, a line synchronization technique synchronizes the generated power with the power on the grid when coming back on-line. The line synchronization technique limits the rate of synchronization to permit undesired transient voltages.Type: GrantFiled: March 27, 2000Date of Patent: November 13, 2001Assignee: SatCon Technology CorporationInventors: Thomas C.
