Publication number: 20230420870Abstract: A connector to connect to a liquid metal wire includes an opening to couple to a casing of the liquid metal wire and a reservoir, where a portion of a solid metal conductor is positioned within the reservoir. The reservoir is to receive liquid metal to substantially fill a volume of the reservoir and extend through the opening into the fluidic wire, where the reservoir and fluidic wire, when filled with the liquid metal, are to form at least a portion of a liquid metal.Type: ApplicationFiled: September 7, 2023Publication date: December 28, 2023Applicant: Teveri LLCInventors: Gianluca Lazzi, Dulce Maria Altabella Lazzi, Kyle Loizos, Arup Roy, Proyag Datta

Patent number: 11797328Abstract: A virtualization partition (VP) is executed by a virtualization layer. The VP contains guest software that executes in isolation within the VP. The guest software has a background task (BT) that needs to be performed in the future. The BT is virtualized by a BT service that executes outside of the VP. The guest software registers the BT, through the virtualization layer, with a BT virtualization service. An event occurs outside of the VP that triggers the BT. The BT virtualization service responds to the event by assuring that the VP is available (executing), and optionally triggers (possibly indirectly) the execution of code in the application.Type: GrantFiled: October 14, 2019Date of Patent: October 24, 2023Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Margarit Chenchev, Benjamin M. Schultz, Gopikrishna Kannan, Graham Wong, Harish Srinivasan, Arup Roy, Hari Pulapaka

Patent number: 11298266Abstract: 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.Type: GrantFiled: December 7, 2017Date of Patent: April 12, 2022Assignee: Second Sight Medical Products, Inc.Inventors: Arup Roy, Avraham I.

Patent number: 11224746Abstract: In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation, which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue is not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes, as continued use may result in neural damage and further electrode damage. The present invention presents system and stimulator control mechanisms to prevent damage to neural tissue.Type: GrantFiled: July 18, 2019Date of Patent: January 18, 2022Assignee: Second Sight Medical Products, Inc.Inventors: Robert Jay Greenberg, Kelly Hobart McClure, James S.

Patent number: 10898713Abstract: The present invention is an improved system for use of eye tracking including spatial mapping percepts in a visual prosthesis by presenting an electrically induced precept through a visual prosthesis, requesting a subject look to the direction of the percept and tracking their eye movement. Eye movement is both faster and more accurate than asking a visual prosthesis user to point to the location of a percept. This method can be beneficial in a retinal prosthesis, but is particularly useful in a cortical visual prosthesis where visual cortex does not match the retinotopic map. Methods are presented for calibrating an eye tracker. Eye tracking hardware may also be used for blanking video information base on the subject's natural blink reflex.Type: GrantFiled: February 22, 2017Date of Patent: January 26, 2021Assignee: Second Sight Medical Products, Inc.Inventors: Avraham I Caspi, Jessy D Dorn, Arup Roy, Robert J Greenberg

Patent number: 10773083Abstract: Systems and methods for detecting and displaying obstacles to visually impaired persons are disclosed. Images from a captured scene are analyzed to detect obstacles. A V-Disparity algorithm is employed to detect the ground plane and remove it from the images, thereby enhancing the capacity of retinal implants to display only obstacles. The system includes cameras to capture images; a processor with memory to detect obstacles in the captured images, to remove a ground plane, and to calculate a map of pixels representing the obstacles; and a retinal implant configured to receive the map of pixels and display the obstacles to a system user by electrically stimulating retinal nerves. The method includes synchronizing captured images and calculating a disparity map between the captured images to detect obstacles and remove a ground plane from processed images. A map of pixels representing the obstacle is transmitted to a retinal implant.Type: GrantFiled: September 15, 2015Date of Patent: September 15, 2020Assignee: Second Sight Medical Products, Inc.Inventors: Robert J.
