  • Publication number: 20240160330
    Abstract: A wearable sensor device includes a liquid metal wire that includes an elongated tube with an internal cavity having a uniform cross-sectional geometry, the internal cavity is at least partially filled with liquid metal. The wearable sensor device further includes detection circuitry to detect a change in an electrical attribute of the liquid metal wire based on a temporary change in the cross-sectional geometry, and generate sensor data to identify an event associated with a wearer of the wearable device based on the temporary change in the cross-sectional geometry.

  • Publication number: 20230420870
    Abstract: 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.

  • Patent number: 11797328
    Abstract: 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.

  • Patent number: 11298266
    Abstract: 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.

  • Patent number: 11235151
    Abstract: 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, zooming the processed image to the input field of view and highlighting the predetermined pattern in the processed image in response to the indication.

  • Patent number: 11224746
    Abstract: 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.

  • Patent number: 10898713
    Abstract: 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.

  • Patent number: 10780272
    Abstract: The present invention is a fitting system with a graphical interface with specific interface screens for specific functions. Methods and devices for fitting a visual prosthesis are described. In one of the methods, threshold levels and maximum levels for the electrodes of the prosthesis are determined and a map of brightness to electrode stimulation levels is later formed. A fitting system for a visual prosthesis is also discussed, together with a computer-operated system having a graphical user interface showing visual prosthesis diagnostic screens and visual prosthesis configuration screens.

  • Patent number: 10773083
    Abstract: 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.
