    摘要： Apparatus, system, and computer-readable media measure electroencephalography (EEG) signals or ERG signals generated from a device that presents a series of images on a timing cycle to a subject. The apparatus comprises a Central Processing Unit (CPU), Power Supply Unit (PSU), Random Access Memory (RAM), and a hard drive (HDD). The apparatus further includes at least one electrode and a photo-sensor like a photodiode for conversion of light into electric current. The CPU is operable with software for converting the EEG or ERG signals evoked from the visual stimuli to provide data and retrieving the status of EEG signals.

    摘要： Apparatus, system, and computer readable media determine the probability of visual recognition of an image by a subject using electroencephalography (EEG) corresponding to a Visual Evoked Potential (VEP). The apparatus comprises means for presenting a series of visual stimuli corresponding to said image to evoke EEG signals. The visual stimuli of the image are presented in an orientation sequence based on a timing cycle. At least one prism is provided for placement in front of the series of visual stimuli corresponding to said image. The EEG signals evoked in response to said visual stimuli and said prism placed in front of said visual stimuli are recorded and processed by a processor. VEP is generated corresponding to the presence of a shift and thereby provides object statistic reliability of the visual recognition of the image by the subject.

    摘要： A filter holder which clips on to an ophthalmic trial refraction frame or clip on to a person's spectacles with a clip on attachment is disclosed comprising a knob which rotates a shaft and a gear. The gear engages a ring with teeth in it. This ring is attached to a plate which has a channel cut through it, a pin to locate the position of the variable neutral density filter and a locking disc which holds the filter against the plate. On the back of the filter holder is a disc with an aperture mounted off the axis of symmetry of the filter holder so that the aperture is aligned with the channel in the edge of the plate. The patient sights through the aperture, the channel and the variable neutral density filter. By turning the knob, the neutral density filter rotates and the density in log units can be read on a scale on the front of the body of the filter holder.

    摘要： The invention consists of an apparatus and method for creating high resolution, high contrast images to enhance the functional vision of visually impaired individuals. The apparatus includes an image scanning device, a digital image enhancement device and a high resolution monitor. Video images are enhanced in real time by converting an analog input signal to a digital output. The digital output is processed in a contrast selection device, stored in high speed memory, reformed into an output image and displayed on the high resolution monitor using high scan rates. The enhancement of images containing text substantially eliminates "grey" transitions between the text and the background to improve resolution. By increasing the contrast between the text and the background as well as user selectable enlargement and character spacing by magnifying or scaling of the digital video data, the functional vision of visually impaired individuals is improved.
