Cycling is a great cardiovascular activity that's generally easy on the joints because it's not weight bearing, although back pain seems to be relatively common among cyclists. According to research, about 68% of people who cycle frequently experience debilitating back pain related to cycling at some point in their lives. Back pain from cycling has a number of causes, mainly: unsuitable bike dimensions and poor sitting posture.

The best way to prevent this problem is purchasing a bike according to one size but this is impractical for the masses of peoples because many people select a new bike based on price point and tend to downplay the importance of the bike's dimensions and ergonomics. Ideally, a bike should be ...

The objective of this design is to create a swarm 3D printing and assembly platform which employs a swarm of printhead-carrying mobile robots to complete sophisticated manufacturing tasks. Similar to how a swarm of bees working together to build their beehive, the swarm of smart mobile robots can work together to print and assemble products based on digital models on demand.

Illustrated here is a model of future factory, consisting of modularly designed tiles for the factory floor to guide the navigation of the robots, mobile robots carrying robotic arms with different end effectors, including filament extruder, gripper for pick-and-placing pre-manufactured components, and other types of robotic toolheads. All the robots are wirelessly connected into the Internet through Wi-Fi ...

Nearly 300,000 Americans have sustained some form of spinal cord injury (SCI), and effective therapies to promote recovery of neural function are lacking. Our vision is to create an off-the-shelf spinal cord implant to replace the injured tissue.

We used the natural spinal cord architecture as a template to design a scaffold that mimics the intact cord. We chose materials with mechanical properties that are similar to the spinal cord properties in order to allow superior integration. We then used rapid 3D printing technology that can fabricate the implant in one continuous print, rather then layers as being done by common inkjet 3D-printers. The interface between each layer is a mechanically weak area; our method produce a more stable ...

The Freight Transport System

Overview:
One of the key components for the future of a country is an efficient, effective, and scalable infrastructure. As such, I propose a major addition to the transportation infrastructure. This proposal greatly improves freight handling efficiency and cost, while significantly reducing environmental impact. It uses existing technology in a new and significantly improved way to create massive long term, high paying jobs at every level in multiple industries as well as local and federal governments. It also creates an infrastructure of great value to national security in the event of a crises or war.

Problem Statement:
For decades there has been a major shortage of long-haul truck drivers resulting in fatigue, sleep deprivation, and little time for families. ...

Energy is one of the main currencies in our world. One of the sources of energy is solar power. Since it is a renewable power source, countries all over the world are adopting it primarily among wind power, geothermal and hydropower. Scientists all over the world are always desperate to find ideas on a new power source and increase the efficiency of the existing ones. This project proposes a new concept on increasing the performance of solar panels by utilizing photons better than the existing solar panels. The current (flat) solar panels efficiency is very small compared to the space they take and cost spent on manufacturing and maintenance. Basically, solar panel work using sun rays to produce electric ...

We live in a coastal town in India called Pondicherry famously known for its serene beaches and coastal activities. Over the years, as the city has developed, it has attracted more tourism, which has resulted in an increase of littering on the once clean and beautiful beaches. This problem is not unique only to Pondicherry but to hundreds of other coastal communities as well.

A recent study by National Geographic estimates that 9 million metric tons of plastic waste enters the world’s ocean from coastal regions. Not only are people affected by this, but this is causing havoc to marine life.

Our innovation, Maritime, is an amphibious rover that is scalable and low-cost which focuses on tackling this worldwide ...

I intend to make the production of electrical energy cheaper and less polluting. My invention is a heat pipe engine. A heat pipe has two ends, a wick and a channel for the vapor to flow between the two ends shown in figure 1. A high concentration liquid saturates the wick at one end. A low concentration liquid saturates the wick at the other end. The low concentration liquid will flow through the wick into the high concentration liquid. Within the wick are two electrodes 1 and 2. Electrode 1 is located in high concentration liquid, and electrode 2 is in the low concentration liquid. When heat is applied to the end with the high concentration liquid, some of ...

The National Fire Protection Association (NFPA) says pets are responsible for over 1,000 house fires every year in the United States, and an estimated 40,000 pets die in fires, mostly from smoke inhalation, With all the high tech consumer products hitting the market every day, there is NOT 1 product that even hints to benefit a stranded pet locked inside a home once a fire breaks out, NOT A ONE, nothing. Until now. With this new product on the market, your vote is a vote towards the 40,000 pets that are doomed to die this year.

When the smoke alarm goes off, the sensor on the doggy door activates to release the exiting side of the pet door, once ...

This system uses Machine Learning to classify bank notes. Trained on self-taken images of up to 7,000 taken under different various conditions of the environment and money conditions such as wet, crunched and dirty notes. it currently has only been trained and tested on Malawian bank notes. The system is continuously trained and tested for improvements.

Using computer vision, it gets an image of a bank note and starts to look for the specific features that make that money unique. it then cleans the image data and feeds it to the frozen convolution neural network model that spits out a result. The result is an array of labels which in our case are names of the various bank notes ...

Various mechanisms are known for lifting and moving cargo. At the same time, we (Grigori and Oleg Lishanski, US Patent No. 10,214,398 B2, Feb. 26, 2019) developed and tested a simple device that is able to economically move a load overcoming the force of gravity. The device is a platform that is supported on the supporting surface. The supporting surface can be installed vertically or at any arbitrary angle to the horizon. A generator of mechanical vibrations (electrovibrator) and a load are installed on the platform. The vibrator allows you to create longitudinal-axial elastic mechanical oscillations of the platform with a given frequency and amplitude relative to the axis of the fixed bearing surface Fig 1. When the vibrator ...
