Multiphase electric machines possess several advantages when used in the electric drive system for automotive, aerospace/defense, rail, marine, and manufacturing industries. The performance of an electric drive system in extreme working conditions is extremely compromised. An electric drive suffers from torque derating, a decrease in efficiency,
In many types of rotating equipment (cars, boats, helicopters, pumps, compressors), regular wear and tear bring about a gradual increase in unbalancing of the rotating components. In an industrial settings, unbalancing is one of the most common causes of failures (e.g. bearing wear, mechanical seal; etc.). This unbalance is even more crucial/prevalent in higher-RPM components.
The I-5 and I-84 Realignment and Additional Access into the Area
The I-5 and I-84 interchange in Portland Oregon is the worse congested and most accidents for the state.
Transformer efficiency is the ratio of the output power to the input power. Output power is always lower than the input power due to energy losses. Besides measures put in place to reduce energy losses; including use of laminations, soft iron core and copper wires. Commercially used transformers are still about ninety percent efficient,
The illustrated row-guidance hitch is a simple mechanism that combines articulation and side shift to provide adjustable on-the-go variable draft and position of tools for in-row fieldwork. The hitch adjustments also provide a way to couple with field implements automatically.
The EXPO Engine is a proof of concept system. It was designed, built and operated for the specific purposes of demonstrating both a new IC engine configuration for the optimization of engine efficency when using a hydrogen based fuel,
Our project aims to revolutionize emergency medical services in rural communities by introducing a network of drone-based ambulances. The current healthcare infrastructure in these areas faces numerous challenges, including long travel distances, limited resources, and difficult terrain, which often lead to delays in accessing life-saving medical care. By leveraging drone technology,
This concept is to add a series of 4 or 5 miniature wind turbines captured within an aerodynamic designed housing located at the top of a windshield on EV applications. The concept is to utilize the wind velocity flowing up from the windshield to accelerate the air flow through the turbines. In addition,
This is a proposal for a future mandatory interface to support the testing of Connected and Automated Vehicles (CAVs), to be installed in all production vehicles, hence "On-Board Validation" or OBV. This would allow independent validation of CAVs by third parties, and comparative tests between models from different manufacturers.
I personally have to use a wheelchair to get around. While that is fine in and around the apartment I live in but can become very arduous when traveling 8 or 10 blocks or more. Note that I am 69 years old. Unfortunately electric wheelchairs are very expensive (over $10K) which got me thinking on a solution.
