  • Publication number: 20160073907
    Abstract: Systems, devices and methods described herein can be used to monitor and treat cardiovascular disease, and more specifically, can be used to determine heart rate (HR), determine respiration rate (RR) and classify cardiac rhythms based on atrial intracardiac electrogram (IEGM) and atrial pressure (AP) signals. The atrial IEGM and AP signals are subject to spectrum transforms to obtain an atrial IEGM frequency spectrum and an AP frequency spectrum. Based on peaks in the atrial IEGM and AP frequency spectrums measures of HR and RR are determined, and arrhythmias are detected and/or arrhythmia discrimination is performed.

  • Publication number: 20150219093
    Abstract: An industrial fluid circulation system and method has at least one fluid circulation circuit in an industrial process, such as an HVAC system. The at least one fluid circulation circuit includes a plurality of pumps connected in parallel to circulate a fluid through the at least one fluid circulation circuit, with at least two of the parallel connected pumps operating at all given loads. A separate motor drives each pump and a speed control is used to vary the speed of each motor to thereby vary the pumping capacity of each parallel connected pump. A load detector is provided to sense operating loads on the system, and each operating pump runs simultaneously at all loads, relative to a maximum pump speed, at a substantially similar reduced speed, a predetermined equal reduced speed or a predetermined almost equal reduced speed.
