Astronauts who spend long periods of time in weightless environments tend to suffer from loss of bone density and muscle mass. The intent of this idea is to reduce the degree to which astronauts experience these problems.

The idea is to sew elastic bands into coveralls in a way that provides a compressive force along the length of the body and the length of the arms. These loading stimuli simulate the force of gravity on a standing human body, causing the body to resist. This resistance, in conjunction with exercise and bisphosphonate supplementation, should help to maintain bone density.

The dashed lines represent where the elastic bands are sewn into the coveralls. They run along the front and rear ...

With the main target of improving fuel consumption, one of the biggest challenges on harness wiring industries is to reduce weight of the assembled harness. Based on that, research on alternatives to copper wires started with the replacement of copper by aluminum cores which are more cost effective and around 48% weight reduction. This reduction is particularly important as improving fuel consumption will reduce carbon dioxide emissions. However, replacing copper by aluminum is far from an easy process, especially when connecting the aluminum wires with terminals which are mainly composed by copper alloys and when submitted to wet salted environments a galvanic corrosion process starts and all aluminum from the core disappears.

The method to avoid corrosion is protecting ...

GREAT PLAINS DIESEL TECHNOLOGIES, L.C. (GPDT)

GPDT offers continuous direct control of diesel fuel injector needle lift, to control fuel injection flow rate. This is but one application of a robust, durable mechatronic actuator technology.

Origins

In the early 2000s, increasing the speed at which a fuel injector could open and close helped reduce emissions. A faster solenoid was needed to more rapidly shuttle the injector servovalve which in turn directed fuel pressure to only open or close the injector needle. First applied to injectors in 1913, physics limits solenoid speed.

United States Patent 7,255,290 embodies a theory for how to speed up the servovalve using a different actuator technology. After 7,255,290 issued, GPDT was incorporated to test the speed theory.

In India the majority of the people use a 2 wheeler instead of a 4 wheeler all throughout the year except for rainy seasons. The major advantage of a 2 wheeler over a 4 wheeler is that it requires less parking space. In the rainy season people mostly use 4 wheeler in spite of the parking issues to get protection from the rain. This causes a lot of traffic since the size of the roads in most of the places in India are designed to handle a 2 wheeler traffic.

The major motive of this project is that it will reduce the issues related to the traffic and also its cost would be lower than a convertible 4 wheeler. ...

Open kitchen equipment by combining air conditioning and ventilator for a better cooking and dining experience.

To deal with changes of lifestyle, the kitchen becomes an open space in the home for interaction. Coolking brings a better cooking environment facing this dramatic shift.

Coolking blends the functions of air conditioning and ventilator for not only filtering cooking fumes, but adjusting temperature and offering superb air circulation. Cooking fumes are filtered and cooled down via Coolking. It emits cool air and the internal oil filter is easy to clean. Coolking provides a smart flow control for different cooking demands such as stir fry, or cold dishes, implementing emergency fire and linked alarm system when dry-heating incidents occurred. For commercial spaces ...

The Go Kart is a type of open wheel car. Go Karts come in all shapes and size, from motor-less models to high powered racing machines. Some such as Super Karts are able to beat racing cars or motorcycles on a long circuit. It is a small four wheeler run by an I.C Engine. It is a miniature of a racing car. Go Kart is not a factory made product; it can be made by engineers.

This report documents the process and methodology to produce a low cost go kart. Nowadays the go kartss which are available in the market cost more than Rs.1 lakh. We have made a simple, self-fabricated go kart for just 50000 rupees. The chassis ...

This counter rotating fan design would be usable for Hyperloops as well as commercial bullet trains. With respect to a single fan design, counter rotating fans offer a higher pressure ratio, over 6% increased efficiency, lower rotations per minute, and lower power requirements. As seen in aircrafts in the form of propellers, using counter rotating fans fundamentally cancels all torque on the craft. For the modern bullet train virtually all air drag would be neutralized. As vacuuming the entire Hyperloop tube is neither feasible or cost-effective, partial pressure would be kept in the tube. Hyperloop would have counter rotating fans on the nose of the pod to actively transfer high pressure air from the front to the rear of ...
With our world becoming more interconnected, transportation and distribution are vital. With this versatile Hyperloop design, both supersonic pedestrian transport and incredibly fast and efficient product distribution are possible. Hyperloop consists of a pod or capsule inside a tube. To overcome the Kantrowitz limit for the Hyperloop, counter rotating fans on the nose actively bypass flow through the pod, transferring high pressure air from the front to the rear of the vehicle. Moreover, this aerodynamic system provides a higher pressure ratio, lesser power requirement, and lesser weight for the system as a whole. The fans serve other purposes, solving the issue of creating a low friction suspension system at near sonic speeds (proving to work at speeds of Mach ...

Culture patch with monolayer nano-filers on a frame in-vivo like extracellular matrix made of monolayer nanofibers is suited for cell culture and tissue formation. It allows minimizing the exogenous contact and maximizing the uptake rate cells, while the micro-frame and the patch form allow easy handling, easy control of self-organization. Honeycomb frames of different size, shape and elasticity are producible. Nanofibers made of different materials such as gelatin, collagen, PLGA, PCL, PMGI, etc. are also available. The culture patch can be placed in Petri-dish and multi wells for off-ground cell culture. It can also be inserted in Boyden chambers or microfluidic chips. Cells are loaded on the honeycomb frame area and the patch with cells will then be placed ...

The average person living in New York City drinks 3.4 cups of coffee a day. As most of the coffee is drunken in disposable cups on the go, the environmental damage is tremendous. In total, all Americans throw away over 50 billion paper cups every year. That means wasting approximately 20 million trees, 20 billion gallons of water and energy to power 53,000 homes for a whole year.

Cup&Co is a concept that aims at frequent coffee drinkers and provides them with a system to use their own reusable cups more often. Based on the insight that coffee shop owners do not want to introduce a solution that is more expensive or less convenient, Cup&Co focuses on changing the ...
