![]() ![]() Often times the tricorder gave an initial analysis of the new environment. One of the more useful instruments available to "Star Trek" personnel, variations of the tricorder (medical, engineering or scientific) were used to measure everything from oxygen levels to detecting diseases. Spock used to always carry over his shoulder, especially when the crew (usually consisting of only Spock and Captain Kirk) first surveyed a new planet? That was a tricorder. How many of you remember that instrument Mr. It's not good enough to pass the driving test (normal vision is considered 20/20) but it's good enough to read billboards and go about your day without the aid of a seeing-eye dog. What it all means is that in theory, a person with 20/400 sight (blind), due to the loss of retinal cells from retinitis pigmentosa, can obtain 20/80 sight. The photodiodes replicate the lost retinal cells then change light into electrical signals which in turn send nerve pulses to the brain. Those images are reflected back into the retina chips to stimulate photodiodes. Light enters the camera and is processed through a small wireless computer, which then broadcasts it as infrared LED images on the inside of the glasses. The patient receives the implants behind the retina, then wears a pair of glasses fitted with a video camera. The science behind the implants, or bionic eyes as they're commonly referred to, works much the way Geordi's VISOR did. In 2005, a team of scientists from Stanford University successfully implanted a small chip behind the retina of blind rats that enabled them to pass a vision recognition test. Whatever the case, the creators of "Star Trek" were on to something because you'd be hard-pressed to find many people without a cell phone these days. The original flip cell phones are perhaps distant cousins. The "Star Trek" communicator had a flip antenna that when opened, activated the device. Actually, the communicators in "Star Trek" were more like the push-to-talk, person-to-person devices first made popular by Nextel in the mid to late '90s. He'd just whip out his communicator and place a call.įast-forward 30 years and wouldn't you know it, it seems like everyone carries a communicator. And when in distress and in need of help in a pinch, he could always count on Bones to come up with a miracle cure, Scotty to beam him up or Spock to give him some vital scientific information. Whenever Captain Kirk left the safe confines of the Enterprise, he did so knowing it could be the last time he saw his ship. Michael Tullberg/Getty Images Entertainment ![]()
