摘要： The present invention consists of an implantable device with at least one package that houses electronics that receives input data or signals, and optionally, power, from an external system through at least one coil attached to the at least one package, processes the input data and delivers electrical pulses to neural tissue through at least one array of multiple electrodes that is/are attached to the at least one package. The invention, or components thereof, is/are intended to be installed in the head, or on or in the cranium, or on the dura, or on or in the brain.

摘要： The present invention is a depth sensing visual prosthesis. By depth sensing objects within an image, items located at a certain depths from the user can be removed to declutter an image. The resulting image presents only objects within a range of depth from the visual prosthesis user. Depth sensing can be accomplished in various ways including structured light, time of flight, or preferably, a stereo camera pair.

摘要： Electrode arrays for biological implants are disclosed. The present disclosure provides array designs for improving apposition (reducing the space between the array and neural tissue). The present disclosure also provides electrode array designs that can be made approximately spherical to increase the field of view of a visual prosthesis while still maintaining good apposition to neural tissue.

摘要： The present invention is a method of processing a video image in an electronic video processor including the steps of receiving an input image having an input field of view, generating a processed image from the input image, and having an output field of view smaller than the input field of view, searching for a predetermined pattern within the input image, providing an indication when the predetermined pattern is found in the input image, and zooming the processed image to the input field of view and highlighting the predetermined pattern in the processed image in response to the indication.

摘要： The present invention consists of an implantable device with at least one package that houses electronics that sends and receives data or signals, and optionally power, from an external system through at least one coil attached to the at least one package and processes the data, including recordings of neural activity, and delivers electrical pulses to neural tissue through at least one array of multiple electrodes that is/are attached to the at least one package. The device is adapted to electrocorticographic (ECoG) and local field potential (LFP) signals. The output signals provide control for a motor prosthesis and the inputs signals provide sensory feedback for the motor prosthesis. The invention, or components thereof, is/are intended to be installed in the head, or on or in the cranium or on the dura, or on or in the brain.

摘要： Digital image filters and related methods for image contrast enhancement are disclosed. According to one aspect of the method, an invariant brightness level is initially determined. For each pixel of an input image, the invariant brightness level is subtracted from the input brightness of the pixel. The resulting value is multiplied with a contrast adjustment constant. After that, the invariant brightness level is added. Further aspects of the method can involve histogram equalization.
