eSight was founded in 2006 by Conrad Lewis, a Canadian electrical engineer with two legally blind sisters. His motivation was to build a device that would enable his sisters to see, be able to work and independently perform virtually all activities of daily living. [1] [2] The first generation of the device, eSight 1, was released in October.
The ability to give sight to a blind person via a bionic eye depends on the circumstances surrounding the loss of sight. For retinal prostheses, which are the most prevalent visual prosthetic under development (due to ease of access to the retina among other considerations), patients with vision loss due to degeneration of photoreceptors (retinitis pigmentosa, choroideremia, geographic atrophy ...
People in the trial received the implant in only one eye and tests were conducted with the device switched on, or switched off as a control. [5] With the device switched on, about 23% of the subjects had improvements in their ability to see ; all had been at 2.9 or higher on the LogMAR scale and improvements ranged from just under 2.9 to 1.6 ...
A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
An electromagnetic acoustic transducer (EMAT), is a type of non-contact ultrasound that generates an ultrasonic pulse which reflects off the sample and induces an electric current in the receiver. This is interpreted by software and provides clues about the internal structure of the sample such as cracks or faults.
The company develops and manufactures assistive technology devices for individuals who are visually impaired, partially sighted, blind, print disabilities, or have other disabilities. OrCam headquarters is located in Jerusalem, operating under the company name OrCam Technologies Ltd.
In short, blind people perceive to see through touch and audition with sensory substitution. Through experiments with a Tactile-visual sensory substitution (TVSS) device developed by Bach-y-Rita subjects described the perceptual experience of the TVSS as particularly visual, such that objects were perceived as if located in the external space ...
BrainPort is a technology whereby sensory information can be sent to one's brain through an electrode array which sits atop the tongue. [1] It was initially developed by Paul Bach-y-Rita as an aid to people's sense of balance, particularly of stroke victims.
