摘要:
A sensory substitution device (SSD) for providing a person with neural signals responsive to features of an environment, the SSD comprising: at least one camera that acquires an image of the environment; and at least one corneal neural stimulator that stimulates nerve endings in the cornea of an eye of the person to generate neural signals responsive to the image that propagate to the person's brain.

摘要:
A system and method are presented for use in monitoring one or more conditions of a subject's body. The system includes a control unit which includes an input port for receiving image data, a memory utility, and a processor utility. The image data is indicative of data measured by a pixel detector array and is in the form of a sequence of speckle patterns generated by a portion of the subject's body in response to illumination thereof by coherent light according to a certain sampling time pattern. The memory utility stores one or more predetermined models, the model comprising data indicative of a relation between one or more measurable parameters and one or more conditions of the subject's body. The processor utility is configured and operable for processing the image data to determine one or more corresponding body conditions; and generating output data indicative of the corresponding body conditions.
摘要:
A method for prophylactic therapy for post-cataract extraction posterior capsular opacification of an eye having a lens posterior capsule, the method including the step of irradiating the lens capsule with laser radiation so as to destroy cells which remain in the lens capsule after extraction of the cataract, the laser radiation being substantially absorbable in water and of a level less than that required to rupture the lens capsule.
摘要:
Disclosed are methods and devices useful for imaging blood-containing tissue, for example for angiography, especially retinal angiography, whereby an image is generated by dividing pixels of an image acquired at some wavelength range by corresponding pixels of an image acquired at a different wavelength range. In some embodiments, a first wavelength range includes predominantly light having wavelengths between about 400 nm and about 620 nm and a second wavelength range includes predominantly light having wavelengths between about 620 nm and about 800 nm.
摘要:
An apparatus for objectively detecting ocular disorders adapted to the expedient examination of uncooperative patients generally comprises structures for collimating light into two predetermined paths for coaxial illumination of a person's right and left eye; structures for conditioning the collimated light; apertures for illuminating and retroflecting the collimated light by a person's eyes; and structures for detecting the relative intensities of the retroflected collimated light. A method for expediently examining uncooperative patients adapted to objectively detecting an ocular disorder comprises coaxially illuminating each eye; effecting a relative position between the apertures of an apparatus and a patient'eyes so that brief illuminating contact with the collimated light is effected; retroflecting the collimating light illuminating each eye; and measuring the relative intensities of the retroflected collimated light so that ocular disorders can be objectively determined.
摘要:
The invention provides a device for delivering electromagnetic radiation to a limbal area of an eye that transforms one or more beams of electromagnetic radiation that are incident on a first side into one or more emitted beams of the electromagnetic radiation where the one or more beams are arrayed in a cylindrical array, an array of one or more beams each beam having a cross sectional shape of a circular arc or an array comprising a beam having an annular cross section. The invention also provides a system for delivering electromagnetic radiation to the limbal area of an eye that includes one or more devices of the invention and a source of electromagnetic radiation. The system may be used in the treatment of glaucoma.
摘要:
A container having a main storage space for holding a matter, having an inlet/outlet opening and fitted with a PEF system. The PEF system comprises two or more electrodes disposed within said container and contacting the matter; and electric pulse source connected to the two or more electrodes and adapted to pass pulsed electric energy through the matter. The PEF system being activated to deliver a treatment protocol to the matter.
