Publication number: 20240108512Abstract: Methods and apparatuses for cleaning and/or drying a subject's ears and/or nose may include an inverting tubular swab region. These apparatuses may remove debris, such as ear wax & skin debris from the ear canal. These apparatuses are safer than traditional cotton swab. Also described herein are apparatuses configured for use in the nose, which may remove mucus (e.g., snot) from the nasal and sinus regions. These apparatuses may be configured for use with infants and toddlers as an alternative to air aspiration bulb/tool. Also described herein are methods of using any of these apparatuses as well as methods of making and packaging them.Type: ApplicationFiled: October 3, 2023Publication date: April 4, 2024Inventors: Michael P.

Patent number: 9845239Abstract: Systems, devices, and methods combine thermally stable reactant materials and aqueous solutions to generate hydrogen and a non-toxic liquid by-product. The reactant materials can sodium silicide or sodium silica gel. The hydrogen generation devices are used in fuels cells and other industrial applications. One system combines cooling, pumping, water storage, and other devices to sense and control reactions between reactant materials and aqueous solutions to generate hydrogen. Springs and other pressurization mechanisms pressurize and deliver an aqueous solution to the reaction. A check valve and other pressure regulation mechanisms regulate the pressure of the aqueous solution delivered to the reactant fuel material in the reactor based upon characteristics of the pressurization mechanisms and can regulate the pressure of the delivered aqueous solution as a steady decay associated with the pressurization force.Type: GrantFiled: July 1, 2015Date of Patent: December 19, 2017Assignee: Intelligent Energy LimitedInventors: Andrew P.

Publication number: 20150376002Abstract: A water reactive hydrogen generation system includes devices and methods to combine reactant fuel materials and aqueous solutions to generate hydrogen. The generated hydrogen is used in a fuel cell or other application. The water reactive hydrogen generation system includes a reactant fuel chamber, a reactor chamber (zone), a water solution inlet, a hydrogen output port, and a material delivery device. The material delivery device can include a drive screw and a sliding piston to move the fuel material into the reactor zone when a reaction is initiated. As the reaction takes place, the reaction waste product is removed from the reaction zone to allow additional reactant fuel materials and aqueous solutions to be introduced and to continue the hydrogen-generating reaction. A reaction waste product created is exchanged for additional reactant fuel material at determined intervals to allow the reaction to continue until the reactant fuel is exhausted.Type: ApplicationFiled: September 3, 2015Publication date: December 31, 2015Applicant: Intelligent Energy LimitedInventors: Andrew P.

Patent number: 7448013Abstract: There is disclosed a system for designing circuits which involves pre-placing delay elements between circuit components susceptible to shoot-through due to effects of clock skew, each delay element having a physical form and at least one input terminal and at least one output terminal; determining which delay elements are not critical in preventing shoot-through; removing non-critical delay elements from the circuit; and replacing each removed delay element with a cell having a physical form equivalent to the physical form of the removed delay element and a wire connection between an input and an output of the cell equivalent to an input and output of the delay element. This wire cell has the effect of removing the delay element from the circuit without having to reposition the circuit components. This has the result that it is not necessary to re-position circuit components on the removal of delay elements and then to re-evaluate the circuit performance. Circuit design can be significantly improved.Type: GrantFiled: December 29, 2004Date of Patent: November 4, 2008Assignee: Broadcom CorporationInventor: Andrew P. Wallace
