Embodiments of the present application provide a head-mounted assembly, a transcranial light regulation device and equipment for transcranial light regulation. The head-mounted assembly comprises a sheet with a hollow structure and a plurality of light emitting elements, and the sheet at least wraps around the head of the object in the transcranial light regulation state. At least through the hollow structure, the sheet is formed with a front island, a rear island, a pair of side islands between the front island and the rear island, a top island, and a plurality of cross-linking parts connecting adjacent islands. The top island and the rear island, and the hollow structure formed by the cross-linking part between the top island and the rear island form a hair bundle opening. A first part of the plurality of light emitting elements is arranged on the inner side of the rear island facing the object, and the first part is configured to correspond to the occipital region of the object. The hair of the object can be exposed from the hair bundle opening, effectively reducing the hair thickness of the occipital region, and significantly improving the transcranial light regulation effect of the occipital region.

A system for providing warmth and protection to a wearer's head includes headwear configured to cover the wearer's head, neck, face, and first portion of hair. The headwear includes a first end, a second end, a first opening for the wearer's eyes, and a second opening configured to accommodate a second portion of hair. The second opening is positioned such that, when the wearer is wearing the balaclava, the second opening is located beneath an occipital bone, an occipital lobe, and a cerebellum of the wearer. The system can further include a helmet. The second opening can be configured to be positioned below a bottom of a rear portion of the helmet. The first opening can be positioned axially between the first end and the second end of the balaclava. The second opening can be positioned axially between the first opening and the first end of the balaclava.

The application relates to a probe mounting assembly, a head cap and a near-infrared brain function imaging device, comprising a cushion assembly configured to fit the head of a subject and a plurality of probe mounting portions. The cushion assembly comprises a pair of first cushions capable of covering at least the left and right primary motor areas of the subject, a second cushion capable of covering at least the forehead area of the subject, a pair of third cushions capable of covering at least the left and right temporal lobe areas of the subject, and a fourth cushion capable of covering at least the occipital lobe area of the subject. The first cushion comprises a first edge, a second edge and a third edge, the center distance between at least part of the plurality of second cushion probe mounting portions adjacent to the first edge and the first cushion probe mounting portion arranged on the first edge satisfies a preset interval range; the center distance between the plurality of third cushion probe mounting portions adjacent to the second edge and the first cushion probe mounting portion arranged on the second edge satisfies the preset interval range. In this way, the number of detection channels can be increased.

This invention belongs to the field of brain function testing technology, specifically disclosing a method and system for assessing care efficacy based on near-infrared super-scanning. This method uses a near-infrared brain functional imaging (fNIRS) system to simultaneously acquire light intensity data from the prefrontal, parietal, and occipital cortices of subjects performing cooperative cognitive tasks with caregivers, converting this data into oxygenated and deoxygenated hemoglobin concentrations for individual-level analysis. Brain region matching is completed, and interbrain synchronous activity is detected through transfer entropy analysis and combined power spectrum analysis to obtain the magnitude and directionality of interbrain synchronicity. Based on the magnitude and directionality of interbrain synchronicity, the level of care efficacy between patients with cognitive impairment and their caregivers is assessed. This technical solution utilizes super-scanning technology to analyze and obtain the level of care efficacy between patients with cognitive impairment and their caregivers, thereby facilitating focused observation and care for patients with cognitive impairment.

This invention discloses a control system and method for Internet of Things (IoT) devices based on steady-state visual evoked potentials (SSVEP) and augmented reality (AR). The system is applied to wearable AR devices and includes an SSVEP signal acquisition module, an AR display and stimulus presentation module, a processing and recognition module, a wireless communication and control module, and an AR feedback presentation module. The AR module renders a virtual control object with a specific flickering frequency in the user's field of vision, while the acquisition module acquires EEG signals from the user's occipital cortex in real time. The processing and recognition module decodes the user's gaze intent and generates control commands using CCA or deep learning algorithms. Furthermore, the system integrates eye tracking for dual intent verification and utilizes a context-aware module to adaptively switch scene modes. This invention achieves "what you see is what you get" hands-free, silent interaction, effectively solving the control challenges of IoT devices under conditions of hand-occupancy and environmental noise interference, and possesses the advantages of high robustness and low cognitive load.

This invention discloses a graded obstacle avoidance brain-controlled wheelchair and its control method based on steady-state visual evoked potentials (SVPs). By collecting EEG signals from the user's occipital lobe region and combining them with visual stimulation to induce steady-state visual evoked potentials, wheelchair movement commands are generated. Simultaneously, an environmental perception module acquires obstacle information in real time, and the wheelchair movement control module determines the obstacle avoidance status accordingly. Furthermore, the decoding process of the steady-state visual evoked potentials is constrained during the brain-controlled command generation stage, achieving coordinated control of obstacle avoidance warnings and brain-controlled commands. Through graded obstacle avoidance processing and corresponding feedback mechanisms, unsafe control commands are restricted at the generation stage, thereby improving the safety, stability, and applicability of the brain-controlled wheelchair in complex environments.

The present specification provides a lightweight brain function state evaluation device, method and system, wherein the device comprises: a portable head-mounted device provided with a detection electrode group corresponding to the prefrontal lobe, central region, parietal lobe and occipital lobe of the brain; a processing unit configured to determine a four-parameter feature set from a multi-channel electroencephalogram signal, the four-parameter feature set comprising a peak alpha frequency, a 1 / f spectrum slope, an alpha wave relative power and a theta wave relative power; and calculate a brain function state quantitative index value based on a preset mapping relationship according to the four-parameter feature set, the mapping relationship being such that when the four-parameter feature set is the same, a unique brain function state quantitative index value is output. The present scheme can simplify the device structure, simplify the device usage, reduce the device cost, and more scientifically, accurately and reliably evaluate the brain function state, thereby being more suitable for the needs of scenarios such as daily brain function detection and personal daily health management at home.
