Students at Johns Hopkins University in Baltimore, Maryland, have developed an adjustable prosthetic foot with female veterans in mind. The prosthesis, called Prominence, has an adjustable ankle that allows the user to wear heels up to four inches high.
According to a Johns Hopkins press release while there are numerous options for prosthetic feet on the market, most are designed to fit men’s shoes and none can adjust to a heel more than two inches high.
“High heels have become an integral part of the female lifestyle in modern society, permeating through all aspects of life – professional and social,” wrote the five students who graduated earlier this month from the university’s Whiting School of Engineering in their final project report. “For female veterans of the U.S. armed services with lower limb amputations, that seemingly innocuous, but so pervasive, and decidedly feminine part of their lives is gone.”
The students sought to bring it back. However, creating a prosthetic foot that can work with a four-inch high heel is not an easy task.
First they had to design a foot that adjusts to a range of heel heights without a separate tool. It also had to hold the position without slipping, support up to 250 pounds, weigh less than three pounds, and of course, be slender enough to accommodate high heel shoes.
According to Luke Brown, one of the Johns Hopkins students, the human foot “took thousands of years of evolution to get this way, we have one year to match it.”
Over two semesters, the students fielded a number of prototypes: one with a balloon in the heel it give some spring in the step — that didn’t work. Another idea involved a mouse-trap spring, also a no go.
The final design used a mechanism with two interlocking aluminum disks that open and close with an attached lever at the ankle. An off-the-shelf hydraulic unit was used for the ankle to allow for a smooth gait.
Prominence was tested by seven people, including three amputees. While the initial goal was to create a foot that could work with high heels, an adjustable prosthetic means even greater flexibility for amputees once Prominence hits the market.
“I had a good time walking [with it],” said Alexandra Capellini, a junior at Johns Hopkins University, who lost her right leg to bone cancer as a child. “It felt stable … An adjustable ankle is useful in contexts even beyond high heels. Ballet flats, sneakers, boots, and high heels especially, all vary in height, so an adjustable ankle opens up opportunities to wear a variety of shoes.”
Police arrest suspected terrorist for 1985 hijacking in which Navy diver Robert D. Stethem was murdered
ATHENS (Reuters) - Greek police have arrested a 65-year-old Lebanese man suspected of involvement in the 1985 hijacking of a Trans World Airlines (TWA) plane in which a U.S. navy diver was killed.
A Greek police official said on Saturday the suspect had disembarked from a cruise ship on the island of Mykonos on Thursday and that his name came up as being wanted by German authorities.
The last time the world saw Marine veteran Austin Tice, he had been taken prisoner by armed men. It was unclear whether his captors were jihadists or allies of Syrian dictator Bashar al Assad who were disguised as Islamic radicals.
Blindfolded and nearly out of breath, Tice spoke in Arabic before breaking into English:"Oh Jesus. Oh Jesus."
That was from a video posted on YouTube on Sept. 26, 2012, several weeks after Tice went missing near Damascus, Syria, while working as a freelance journalist for McClatchy and the Washington Post.
Now that Tice has been held in captivity for more than seven years, reporters who have regular access to President Donald Trump need to start asking him how he is going to bring Tice home.
SAN DIEGO — John Timothy Earnest didn't hide his smirks as he sat in a San Diego courtroom on Thursday, watching surveillance video of Lori Gilbert-Kaye being shot down inside the lobby of a Poway synagogue.
Earnest also smiled as a synagogue congregant testified about running toward the shooter, screaming "I'm going to kill you!" and seeing the gunman "with a look of astonishment or fear" turn and run.
Earnest, 20, is facing one count of murder and three counts of attempted murder in the shootings at Chabad of Poway on April 27. He also faces an arson charge related to an Escondido mosque fire in March, when several people who were sleeping inside escaped unharmed.
Sometimes a joke just doesn't work.
For example, the Defense Visual Information Distribution Service tweeted and subsequently deleted a Gilbert Gottfried-esque misfire about the "Storm Area 51" movement.
On Friday DVIDSHUB tweeted a picture of a B-2 bomber on the flight line with a formation of airmen in front of it along with the caption: "The last thing #Millenials will see if they attempt the #area51raid today."
ISTANBUL (Reuters) - Turkey is ready to act on its southern border with Syria, President Tayyip Erdogan said, after warning that it could take unilateral steps if the U.S. does not establish a "safe zone" in northeast Syria this month.
"Our preparations along our borders are complete," Erdogan told reporters in Istanbul on Saturday before departing to attend a U.N. General Assembly meeting.
