Publication number: 20190262535Abstract: An infusion system determines a volumetric flow rate of infusion fluid delivered by an infusion pump along a flow path based on: an upstream acoustic signal emitted by at least one upstream acoustic sensor and detected by at least one downstream acoustic sensor; a downstream acoustic signal emitted by the downstream acoustic signal and detected by the upstream acoustic sensor; and a phase delay between the upstream acoustic signal and the downstream acoustic signal either upstream or downstream. The infusion system automatically adjusts the infusion pump based on the determined volumetric flow rate to achieve a desired volumetric flow rate of the infusion fluid along the flow path.Type: ApplicationFiled: June 8, 2017Publication date: August 29, 2019Inventors: Gary David SHUBINSKY, Jeffrey Donald MERWIN, Tamas BAN, Ion Vergil NICOLAESCU

Patent number: 8864670Abstract: An ultrasonic monitoring device includes a substrate, a plurality of ultrasonic transducer elements, a computer readable memory medium, a microprocessor, and a power source. The ultrasonic transducer elements are coupled to the substrate. Each ultrasonic transducer element is separately configured to transmit a signal to a target area of a mammal and to receive an echo return signal from the target area. The computer readable memory medium includes program instructions. The microprocessor is coupled to the ultrasonic transducer elements and to the computer readable memory medium for executing the program instructions to determine a physiological parameter of the mammal based on a combined analysis of the echo return signals received by the ultrasonic transducer elements. The power source is coupled to at least one of the ultrasonic transducer elements, the computer readable memory medium, or the microprocessor for supplying electrical energy.Type: GrantFiled: January 26, 2012Date of Patent: October 21, 2014Assignee: Hospira, Inc.Inventors: Ronald S.

Patent number: 7384145Abstract: A system and method for obtaining information about the spatial distribution of photoreceptor activity and neural activity in the retina using simultaneously recorded multiple biopotential signals. The information thus gathered is used to assess retinal dysfunction due to trauma or disease. The biopotential signals are recorded from the surface of the eye and head using a plurality of electrodes, including those integral to a contact lens. The biopotential signals are recorded before, during and after the presentation of an optical stimulus to the subject eye. The recorded biopotential signals are then analyzed and interpreted to reveal the distribution of photoreceptor activity and neural activity across the retina. The analysis and interpretation of the biopotential signals is quantitative, and makes use of an electromagnetic model of the subject eye. The subject may be animal or human.Type: GrantFiled: February 15, 2007Date of Patent: June 10, 2008Assignee: The Board of Trustees of the University of IllinoisInventors: John R.
