腦機(jī)接口專利公開趨勢

發(fā)明名稱	Brain implant with subcutaneous wireless relay and external wearable communication and power device
解決的技術(shù)問題	Brain-machine interfaces (BMIs) hold tremendous promise for the restoration of sensory and motor function and the treatment of neurological disorders. Most of these applications require fine scale communication—at the level of individual neurons—with large numbers of neurons across multiple brain areas. There are not yet any clinically translatable approaches for achieving this level of brain interfacing.
技術(shù)方案	A brain-machine interface (BMI) is described in which many flexible electrodes for implanting within a subject's brain run to a cylindrical sensor device configured to fit inside a burr hole in the cranium. The devices contain sealed electronics that convert analog neural voltages to digital signals, or vice versa, and connects through a serial cable to a subcutaneous relay on the mastoid region (behind the subject's ear) or other suitable location. The relay draws power from and communicates with an externally worn device and distributes the power to the devices. The externally worn device communicates wirelessly or through a tether to a base station computer for data analysis and/or stimulation.

發(fā)明名稱	Brain-controlled body movement assistance devices and methods
解決的技術(shù)問題	Patients who have experienced a brain injury (e.g., stroke, trauma, infection, hemorrhage, neonatal malformation, cerebral palsy, or neurodegenerative) typically undergo some type of rehabilitation in an attempt to restore or strengthen the motor impaired or paralyzed side of the body, often using a variety of rehabilitation devices that aid in the rehabilitation effort. Often, the rehabilitation method involves equipment that requires the patient, in order to perform the necessary rehabilitation activities, to be at a particular location such as a rehabilitation facility where the equipment is located.
技術(shù)方案	Methods, devices, systems, and apparatus, including computer programs encoded on a computer storage medium, for brain-controlled body movement assistance devices. In one aspect, a device includes a brain-controlled body movement assistance device with a brain-computer interface (BCI) component adapted to be mounted to a user, a body movement assistance component operably connected to the BCI component and adapted to be worn by the user, and a feedback mechanism provided in connection with at least one of the BCI component and the body movement assistance component, the feedback mechanism being configured to output information relating to a usage session of the brain-controlled body movement assistance device.

發(fā)明名稱	Systems and methods for generic control using a neural signal
解決的技術(shù)問題	Currently for brain computer interfaces (BCIs), users are asked to either perform a task-relevant mental task to perform a given target task (e.g., try moving a cursor when the target task is to move a cursor) or are asked to perform a task-irrelevant mental task to perform a given target task (e.g., try moving your hand to move a cursor to the right). Furthermore, current BCIs only allow users to use the thought (e.g., the task-relevant mental task or the task-irrelevant mental task) to control a pre-defined target task that is set by the researcher. This disclosure describes novel methods and systems that prepare and allow BCI users to utilize a given task-irrelevant thought to independently control a variety of end-applications, including software and devices.
技術(shù)方案	Universal switch modules, universal switches, and methods of using the same are disclosed, including methods of preparing an individual to interface with an electronic device or software. For example, a method is disclosed that can include measuring brain-related signals of the individual to obtain a first sensed brain-related signal when the individual generates a task-irrelevant thought. The method can include transmitting the first sensed brain-related signal to a processing unit. The method can include associating the task-irrelevant thought and the first sensed brain-related signal with N input commands. The method can include compiling the task-irrelevant thought, the first sensed brain-related signal, and the N input commands to an electronic database.

發(fā)明名稱	Fluorinated elastomers for brain probes and other applications
解決的技術(shù)問題	Decoding neural signals is of fundamental importance to bridge the existing gap of knowledge between our molecular understanding of synaptic circuits and behavioral neurosciences. Understanding neurodegenerative diseases or brain circuitry in general, and increasing the bandwidth of brain-machine interfaces for novel medical devices such as neuroprostheses or deep brain stimulators, are, to name a few, potential applications that would benefit from advanced neural interface technologies. However, probing the dynamic of neural network on a sufficiently large spatial and temporal scale to understand neural encoding requires simultaneous measurements on tens, if not hundreds of thousands of neurons, in vivo , over time. Moreover, each neuron itself can have tens to hundreds of thousands of synaptic connections, which can extend throughout the entire volume of the brain. Therefore, chronically stable and brain-wide activity mapping is needed to understand the connectome of the brain.
技術(shù)方案	Articles and devices comprising fluorinated polymers, as well as methods of preparing fluorinated polymers, are generally described. In some cases, such fluorinated elastomers can be used for sensing neural activity, e.g., by encapsulating electronic circuits, or other applications. Furthermore, according to certain embodiments, polymers can, surprisingly, be directly deposited onto layers comprising low molecular weight fluorinated polymers, e.g., without swelling in the presence of certain solvents. Some embodiments are generally directed to devices and methods for treating fluorinated polymers and subsequently depositing material onto the treated fluorinated polymers. This may allow the fabrication and patterning of multilayered articles comprising fluorinated elastomers.
