Abstract: This study concerns a robust control algorithm of an innovated structure of linear switching synchronous motor dedicated to monitoring of automated elevators. This control algorithm is based on the pulse width modulation technique imposing currents sum of a continuous value and a value having a shape varying in phase opposition with the variation of the inductances. This control technology can greatly reduce vibration of the entire system due to the strong fluctuation of the torque developed by the actuator, generally characterizing switching synchronous motors. A modelling program taking in account of system interactions is developed. This program is ...
The RoFo WOODEN BARREL BevDisHeadgear beverage dispenser while worn on an individual’s head, a second person can operate it by means of turning the front RoFo WOODEN BARREL Motific Spigot, dispensing one’s favorite refreshment into a glass or into another person’s mouth. A headgear for dispensing a substance has a container to carry the substance. A spigot is secured to the container. The spigot can be opened to dispense the substance by gravity, suction, pressure or levity flow when the container. The spigot can be closed to retain the substance in the chamber. A hat-like recess is formed within ...

SaferEx - Multi-action Water Purifier is an innovative multi-action and safe colourless liquid that purifies unsafe borehole/well and containerized water, makes it safe for drinking, hygiene and sanitation uses to prevent the prevalent waterborne diseases and deaths. It has been effectively and economically confirmed to purify unsafe fresh and salt borehole/well water by disinfecting/killing pathogens (bacteria, viruses, protozoa, etc) in the water; sedimenting suspended particles, metals that cause water hardness (Calcium and Magnesium) and staining (Iron and Manganese), and salts, removing colour, odour, and taste, among others, "in a single application and a unit process", like never before; by ...
Preliminary name of concept.
Saha (which means working together) will be a project management tool that can be used by various roles in an organization thereby reducing miscommunication and communication gap. This tool also captures and presents only the right amount of information resulting in simplicity in terms of project management for PMO.
Who will be using the application.
This tool can be used by all project stakeholders in an organization ranging from highest level of hierarchy such as CXOs to Project Managers to Development Team, HR etc.
How will the concept be monetized?
This tool will be a SaaS based subscription software. ...
When people lack easy and reliable clean drinking water access, it is a major burden on their lives. Beyond basic health concerns and the fact that 500,000 people die annually as a direct result of diarrheal illness from inadequate drinking water, daily struggles also include having to walk far distances and wait in long lines at community water points.
By placing water filters right inside people’s homes, OHorizons is working to mitigate these issues.
We’ve engineered a Wood Mold for the production of concrete BioSand Filters (BSFs). Our low-tech design is affordable, utilizes 100% locally-sourced materials, tools, and ...
The lamp is a light-emitting diode (LED) product assembled in series and parallel for use in lighting fixtures. It’s an upgrade of SHEKARAU LAMP you know. It has a lifespan and efficiency (electrical and mechanical) more than existing Shekarau lamps, and are significantly more efficient than 26 watt compact fluorescent lamps.
This lamp has been in existence in Kano state around 2004 during Malam Ibrahim Shekarau administration. It is named by the local people as then he was the seated governor of Kano state.
The lamp use abundant northern Nigeria solar energy as a cost effective and ...
With "concussions" so much in the news of late we decided to go beyond what the NFL is doing with sensors in the helmet monitoring the impact forces to be WI Fi'd to the side line to engage "Concussion Protocol."
We have designed an inner sports helmet sports liner (also for military helmet application) to substantially reduce the shock of head impact trauma. This proprietary patent pending sports liner utilizes OACS (Opposing Articulated Composite Springs) to decelerate impact load force to the wearer's head.
Under impact load, the specially positioned OACS (Front, Top Side and Back) rotate and compress ...
I am proposing a device that will help in reducing the drinking water shortage at different regions in the world.
Clean, safe drinking water is scarce. Today, nearly 1 billion people in the developing world don't have access to it. Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles.Water is the foundation of life. And still today, all around the world, far too many people spend their entire day searching for it. In places like sub-Saharan Africa, time lost gathering water and suffering from water-borne diseases is ...
I got tired of so many beverage bottles thrown away with contents still inside. I realized this was due in many cases to the user being unable to locate their bottle because it was placed amongst other that looked just like it. This situation occurs in at home, work, or on-the-go: anywhere that people gather. To avoid drinking from somebody else's bottle, most people open a new bottle, leaving the unfinished bottle to be disposed of, putting an unnecessary strain on the environment in the form of: excess pollution (at least twice as much waste); wasted water (found in ...
If you could go anywhere in one machine, would you?
SkyRunner is not only the next big step in elite powersports but it's in a league of its own. Where you can go, others simply can't follow. Imagine the adventures possible when the end of a long trail, edge of a surging river, or base of a continental plateau are no longer limitations for your off-road expedition.
SkyRunner combines Bond-esq luxury with the true ruggedness of an off-road machine and one of the safest forms of aviation. SkyRunner’s patent pending technology transforms an ...
