Publication number: 20070239215Abstract: A medical device identifies a hemodynamically unstable arrhythmia based upon optical hemodynamic sensor signals. The optical hemodynamic sensor includes a light source for transmitting light corresponding to first and second wavelengths through a blood perfused tissue of a patient and a light detector for generating optical signals corresponding to an intensity of the detected light at the first and second wavelengths. At a low motion period for the patient, optical signals are obtained from the optical hemodynamic sensor and are analyzed to determine a baseline motion level for the patient. Subsequent signals obtained from the optical hemodynamic sensor are compared to the baseline motion levels, with only those signals corresponding to periods where motion does not exceed the baseline level of motion being further analyzed to determine if they are consistent with a hemodynamically unstable arrhythmia.Type: ApplicationFiled: March 31, 2006Publication date: October 11, 2007Inventors: Sourav Bhunia, Walter Olson, Can Cinbis

Publication number: 20050049647Abstract: An externally actuable, hermetically sealed switch is incorporated with an implantable medical device (IMD). A patient applies pressure against the tissue over the IMD and actuates the switch. The actuation of the switch causes the IMD to take predetermined actions, such as recording data, inhibiting therapy, initiating therapy, increasing therapy, requesting information, initiating a communications session, or performing a status check. Thus, the patient is able to interact with the IMD without requiring an external device such as a programmer, patient activator or magnet.Type: ApplicationFiled: August 29, 2003Publication date: March 3, 2005Inventor: Walter Olson

Patent number: 4294316Abstract: The present machine peels strips of sod from the ground and conveys them upwardly and rearwardly to power driven horizontal rollers. Cutting knives just ahead of these rollers cut the sod strips transversely into pieces of a predetermined length. At the same time, a horizontal platform is raised below the rollers, and upwardly projecting fingers on this platform pass between the rollers and lift the cut pieces of sod off the rollers. During the up and down movement of the platform the oncoming sod strips are held back on the conveyor. A transfer apparatus moves horizontally between a position overlying the rollers, where it receives the sod pieces after they are lifted off the rollers, and a stacking location at one side of the rollers, where it releases the sod pieces to drop by gravity into neighboring stacks. The timing of such release is varied periodically so that the stacks of sod pieces will overlap laterally at intervals.Type: GrantFiled: April 25, 1980Date of Patent: October 13, 1981Inventors: Victor H. Hedley, Walter A. Olson
