Publication number: 20240336344Abstract: A thruster system for improved steering and maneuverability of a marine vessel when operating at relatively low, or wakeless speeds, such as in the vicinity of docks, swimmers or other obstacles, or when trailering, beaching or mooring. The thruster system has a modularized design adapted to independently control separate motor/propeller units located at various positions on the vessel's hull. Each propeller of the modular thruster motor system has its own relatively small, electric motor and mounting bracket, permitting each motor to be separately mounted to a location on the hull of the marine vessel apart from other thruster motors. The thruster system is further enhanced by an electrical control system for controlling each modular thruster motor system of the thruster system. In some embodiments, a charging system is provided that permits each electrical control system to be separately charged from the marine vessel's main battery.Type: ApplicationFiled: June 17, 2024Publication date: October 10, 2024Inventors: Robert D. Christensen, Martin Johnson, Eric Nofsinger, K. Ryan Christensen

Patent number: 11827318Abstract: A submersible marine lighting apparatus is provided that includes voltage up-conversion and that is configured to intensify emitted light by reducing a transmission angle of the light through one or more techniques including increasing the distance between the light emitter and an optical lens. The submersible marine lighting apparatus includes a circular base, an LED array positioned in a recess in the base, an optical lens, a lens gasket, and a retaining ring. The lens gasket cooperating with the circular base, optical lens and retaining ring to form a waterproof seal between the circular base and the retaining ring. When attached to a watercraft, the interior of the lighting apparatus is sealed from water.Type: GrantFiled: February 10, 2020Date of Patent: November 28, 2023Assignee: Liquid Lumens, LLCInventors: K.

Publication number: 20140364833Abstract: Methods and devices can be used to harvest fetal blood from a placenta. In some instances, the blood is used in laboratory testing so that no such blood is drawn from an infant for such testing. In other or further instances, harvested blood can be used in an autologous transfusion. Such procedures can eliminate the drawing of any blood directly from the neonate.Type: ApplicationFiled: May 17, 2012Publication date: December 11, 2014Applicant: INTERMOUNTAIN INVENTION MANAGEMENT, LLCInventors: Robert D. Christensen, Vickie L. Baer, Troy Jesse Orr

Publication number: 20120267335Abstract: An apparatus includes and ampoule and a protective sleeve. The ampoule includes a body portion and an openable end portion. The body portion defines an internal cavity for containment of a substance. The openable end portion is configured to be opened by removal of a distal section, which upon removal creates an opening into the internal cavity of the body portion for liberation of the substance from the internal cavity. The protective sleeve is disposed over at least a portion of the openable end portion. The protective sleeve provides a contamination barrier to prevent contamination of an outer surface of the openable end portion covered by the protective sleeve.Type: ApplicationFiled: October 19, 2011Publication date: October 25, 2012Inventors: Chris Cindrich, Robert D. Christensen
