iPhone Addition as Alternative to Expensive Ophthalmology Equipment

Researchers at the Stanford University School of Medicine have developed two inexpensive adapters that enable a smartphone to capture high-quality images of the front and back of the eye. The adapters make it easy for anyone with minimal training to take a picture of the eye and share it securely with other health practitioners or store it in the patient’s electronic record.

The researchers see this technology as an opportunity to increase access to eye-care services as well as to improve the ability to advise on patient care remotely.

The standard equipment used to photograph the eye is expensive — costing up to tens of thousands of dollars — and requires extensive training to use properly. Primary care physicians and emergency department staff often lack this equipment, and although it is readily available in ophthalmologists’ offices, it is sparse in rural areas throughout the world.

“Adapting smartphones for the eye has the potential to enhance the delivery of eye care — in particular, to provide it in places where it’s less accessible,” said Myung. “Whether it’s in the emergency department, where patients often have to wait a long time for a specialist, or during a primary-care physician visit, we hope that we can improve the quality of care for our patients, especially in the developing world where ophthalmologists are few and far between.”

“A picture is truly worth a thousand words,” he added. “Imagine a car accident victim arriving in the emergency department with an eye injury resulting in a hyphema — blood inside the front of her eye. Normally the physician would have to describe this finding in her electronic record with words alone. Smartphones today not only have the camera resolution to supplement those words with a high-resolution photo, but also the data-transfer capability to upload that photo securely to the medical record in a matter of seconds.

Hacking the Standard Bike Wheel

The Copenhagen Wheel stores energy (from braking…) and provides it when you need it (going up hill…). It is good to see innovation that helps transportation and can encourage people to be more active. Order now for $799.

Hyperloop – Fast Transportation Using a Better Engineering Solution Than We Do Now

Elon Musk (the engineer and entrepreneur behind Tesla electric cars and before that he helped create PayPal) has a very cool idea of how to provide fast long distance transportation (faster than a plane). Essentially it is a big version of pneumatic tubes that used to be used to send small packages around a building, as seen in the movie – Brazil 🙂 Details are scheduled to be released August 12th.

This Is How Elon Musk Can Build the Hyperloop for a Tenth the Cost of High-Speed Rail

Having a elevated Hyperloop main line also completely avoids or reduces many of the pitfalls of ground-level right-of-ways, and opens up some new opportunities as well:

  • The crossing of other right-of-ways, like roads and railways, will be a breeze.
  • Rivers and other terrain obstacles will only be a 10th the problem of rail construction.
  • Hyperloop can avoid tunnels completely by having more flexible choices of right-of-way.
  • An elevated right-of-way opens up new route options, like leasing farmer’s fields using contracts similar to what wind-power companies sign.
  • That could be paid for by leasing Hyperloop’s right-of-way to communications companies for fiber optic cables, cell phone towers, etc.
  • …and let’s not forget the solar power that a couple of square miles of surface area can generate!

Hype Builds Before Elon Musk’s August Alpha Plan for Hyperloop

The Hyperloop would transport passengers from San Francisco to Los Angeles in about 30 minutes and at about twice the average speed of a commercial jet. The system would be on-demand, cheaper than current alternatives, impossible to crash, and potentially, run entirely on solar power.

Travelers ride in pods magnetically accelerated and decelerated into the main tube (like a rail gun) where the air circulates at speed. The air between pods acts as a cushion, preventing crashes, while more air injected through perforations in the tube levitates the pods and reduces friction, much as it might on an air hockey table.

Elon Musk has some very good ideas but what really sets him apart is turning them into functioning enterprises. Great ideas are wonderful but a huge number never go anywhere. Those people that can actually get ideas into the marketplace are the people that provide a much greater standard of living for all of us. And many of them are engineers.

Home Engineering: Automatic Screen Door Closer

A simple solution to a common problem. Using a small pulley, some nylon string and a bottle of sand to create an automatic sliding patio door. It is wonderful to see how creative people can find solutions to improve our lifestyles. Don’t just accept limitation, find ways to make things better.

Introduction Video on 3D Printing

3D printing is an amazing technology that opens up great opportunities for us to enjoy life. The future is great. It is exciting to see how quickly advances are being made in this area. I think the ability to print replacement parts is a huge benefit. And the creative uses people will put these printers too will be a joy to see.

Make Crosswalks More Visible

Good simple idea. And then executed well – for nighttime at least. Crosswalk lights up when in use giving drivers a more visible clue to stop.
