If power must come before work, water is requisite for human survival. Water covers 70% of the earth, but only 1 percent of water is drinkable. In fact,
Since the introduction of electric motors in the modern automotive industry, demand has been increasing for production of smaller and faster motors; as a result, the field of power electronics is being pushed beyond its limits. In order to try to keep up with the rapid changes in motor technologies,
The Problem:
Visually impaired (blind) individuals rely on simple walking sticks for navigating around obstacles encountered in their daily travels. Advanced electronic walking sticks further provide early warning of obstacles detected by sensors, and vibrating of the stick handle. However, the walking stick is only useful if the individual already knows the way to the destination.
The Inverted Gas Turbine
Background
“Warming of the climate system is unequivocal.” [1] Fossil fuels have afforded humanity an unprecedented high standard of living at an equally high cost to the environment. As a run-of-the-river hydroelectric power station supervisor I have had the opportunity to experience firsthand the challenges of periodic unavailability of renewable energy.
The internal combustion engine has been with us for over 100 years, and has seen a myriad of changes in its design, efficiency, and reliability over the years. We have seen carburetors being replaced by fuel injection, dynamos replaced by alternators, and ignition systems seeing many changes,
The Lazy Belt is the world's first 3D printed belt fabricated from a combination of ABS plastic and Thermoplastic Elastomer. The Lazy Belt is for everyone who needs to tighten their pants quickly and easily, but is especially beneficial for people who are losing weight and have dropped 1 to 3 pants sizes.
With this machine, the idea is to harness as much possible energy from as little space as possible.
With the horizontal blade configuration, the turbine doesn't lose energy in the process of resetting each blade to the top of the rotation circuit or in realigning to sudden changes in wind direction.
Classical industrial robots need actuators to be as stiff as possible for placement speed, accuracy and delivering high force. With robotics now moving into applications that require greater adaptability for handling soft or fragile materials and for avoiding injury when working with humans, robotic actuators are increasingly required to offer controlled compliance.
The OmniSign is the world's first all-in-one wireless vital signs monitor. It has the ability to wirelessly measure and record all four vital signs in one application. The OmniSign uses highly specific and specialized sensors to methodically and accurately measure the most important physiologic components of the human body.
By engineering the fire extinguisher into an oval form, three common construction problems and code violations now have a solution.
1. With the OVAL fire extinguisher, walls can now remain at their standard depth if a storage cabinet with a flush door is desired. Most standard walls are framed with 3-5/8” metal studs;
