Abstract: Photovoltaic retinal prosthesis is provided with optically configurable confinement of electrical field. A video stream is projected onto a retinal implant. An array of photovoltaic pixels is configured to provide retinal stimulus responsive to the video stream. The photovoltaic pixels have a common return electrode. Each pixel has an active electrode that is coupled to retinal tissue via a capacitive interface or a faradaic interface. Each pixel includes photodiode(s) connected in series between the common return electrode and the corresponding active electrode. The projected video stream is configured based on a source video stream such that one or more pixels of the retinal implant that will be dark in a next frame of the projected video stream are optically preconditioned (pre-charged) by the projected video stream during the previous frame to become sufficiently conductive to act as transient local return electrodes during the next frame of the projected video stream.

Abstract: Methods and systems capture sounds on multiple sensors of a device worn by a user to produce streams of audio signals as preliminary audio output, transform the streams of audio signals and extract features from a resulting transform of the audio signals, and denoise the preliminary audio output by inputting the extracted features to a statistical model or neural network. As a result, a processed signal having a higher SNR than the preliminary audio output is produced. A humanly perceptible output in the form of transcribed text or a voiced version of the user' speech may be generated from the processed signal. The wearable device may be an earbud having microphones dedicated to capture sound conducted through air in an environment in which the user is situated and speech of the user conducted through bone of the user to one of the sensors.

Abstract: The present disclosure provides an information processing method and apparatus, a terminal, and a storage medium. The information processing method according to the present disclosure includes the following steps performed by a plug-in of a browser: obtaining first information of a first page of a first system; based on the first information, determining, in a second system, second information associated with the first information; and displaying, on the first page, a control associated with the second information if the first page is displayed in the browser, wherein a function of the control is associated with the second information. According to the present disclosure, a user can conveniently perform an operation associated with the second information by means of the control.
