Patent number: 11858800Abstract: A fluid exchanger may exchange a fluid (e.g., coolant) in a reservoir (e.g., vehicle radiator) by removing or withdrawing a first fluid (e.g., old, spent, used, etc.) and by introducing a second fluid (e.g., new, clean, etc.). For example, the fluid exchanger may use a negative pressure, suction, or vacuum to draw the first fluid from the reservoir, and subsequently, the second fluid may be transferred into the reservoir using a negative pressure held in the reservoir, a positive pressure applied to the second fluid, or a combination thereof. The fluid exchanger may also include a multi-purpose, hand-held nozzle that can change an operation of the fluid exchanger from a withdrawing mode to a dispensing mode.Type: GrantFiled: February 17, 2023Date of Patent: January 2, 2024Assignee: BG Intellectuals, Inc.Inventors: Michael J. Erwin, Bradley Robert Young, Lucas Mitchell Shaw, Thomas Michael Probus, John Daniel Cheek

Patent number: 11752867Abstract: Revving an engine may be helpful in various contexts, such as when servicing the vehicle. For example, in some types of services, a cleaning agent may be introduced into the intake and surrounding regions of an engine, and the engine may be revved to reduce a likelihood that the cleaning agent might puddle. In some instances, a device can be positioned within a vehicle interior and can be used to automatically rev the vehicle engine by depressing on the vehicle throttle. In other examples, an engine revving device may send a signal to an electronic-controlled throttle actuator.Type: GrantFiled: April 10, 2020Date of Patent: September 12, 2023Assignee: BG INTELLECTUALS, INC.Inventors: Michael Jason Erwin, Thomas Michael Probus, John Daniel Cheek, Lucas Mitchell Shaw, Bradley Robert Young

Publication number: 20210204999Abstract: Instrument and systems for applying ablative energy to epicardial tissue via a subxiphoid access surgical approach. The instrument has a head assembly sized and shaped for a subxiphoid surgical approach to a patient's heart and defines a contact face. The head assembly includes a paddle body, a first ablation electrode, and a second ablation electrode. The ablation electrodes are coupled to the paddle body in a spaced apart, spatially-fixed fashion. The ablation electrodes are exteriorly exposed at the contact face. A tubular member extends from the head assembly and maintains wiring connected to the ablation electrodes. The instrument is manipulable to locate the contact face on epicardial tissue of a patient's heart via a subxiphoid surgical approach, such as between the left and right pulmonary vein junctions of the posterior left atrium.Type: ApplicationFiled: March 18, 2021Publication date: July 8, 2021Applicant: Medtronic, Inc.Inventors: James Skarda, Steven F.

Patent number: 10371694Abstract: Activated clotting time (ACT) tests detect blood clotting time based on the viscosity changes of a test sample, using a ferromagnetic washer lifted to the top of a test chamber and then dropped from the top via gravity; a drop time greater than a preset threshold value indicates clotting of the test sample. Blood samples which have high levels of heparin usually produce very weak clots that may easily be destroyed by the lifting movement of the washer. But if the clot threshold is set low to detect the weak clots, false detections occur during early testing cycles when activators are not fully suspended during the mixing cycle. Improved algorithms for lifting the washer and adjusting over time enable accurate detection of weak clots.Type: GrantFiled: April 21, 2016Date of Patent: August 6, 2019Assignee: MEDTRONIC, INC.Inventors: Daniel Cheek, Lawrence Erickson, Trevor Huang, Tessy Kanayinkal, Craig Petersen, Charlene Yuan

Publication number: 20080275439Abstract: A system for ablating tissue and electrically interfacing with a heart including an electrosurgical instrument, an energy source, and a controller. The instrument includes a shaft maintaining first and second electrodes at a distal section. The electrodes are electrically isolated from one another. The controller controls delivery of energy from the energy source, and monitors electrical signals at the electrodes. The controller is programmed to operate in a monopolar mode and a bipolar mode. In the monopolar mode, the first and second electrodes are electrically uncoupled, and energy from the energy source is delivered to the first electrode in performing an ablation procedure. In the bipolar mode, first and second electrodes are electrically coupled and serve as opposite polarity poles to apply energy to a tissue target site, detect electrical signals at a tissue target site, or both.Type: ApplicationFiled: March 26, 2008Publication date: November 6, 2008Inventors: David Francischelli, Mark Stewart, Daniel Cheek, Brian Ross, Paul Rothstein, Scott Klein, Asif Hameed, Doug Crowe, Kester Batchelor, William Colon

Publication number: 20080206880Abstract: A system and method for determining a coagulation time, e.g., TT, PT, aPTT, and ACT, of a test sample deposited in a test cartridge is disclosed. A cartridge housing having upper and lower major sides and a minor sidewall encloses a test chamber having a test chamber pivot element and is provided with a cartridge port for introducing a test sample into the test chamber,. Ferromagnetic agitator vane leaflets extend from an agitator pivot element supported by the test chamber pivot element intermediate the upper and lower major sides for rotational motion. The agitator vane leaflets can be swept, in response to an external magnetic field, through the test sample in the absence of coagulation. A timer is started when the agitator movement is commenced whereupon the agitator moves freely. Resistance to agitator movement due to coagulation is detected, and the coagulation time is measured.Type: ApplicationFiled: April 19, 2004Publication date: August 28, 2008Inventors: Cynthia Clague, Daniel Cheek, Douglas Nippoldt
