The invention relates to a long-gap discharge leader development speed measurement method based on radiated electromagnetic wave detection. The method comprises a set of high-frequency antennas and a high-speed oscilloscope and a long-gap discharge leader development speed calculating method. The method adopts a certain antenna arrangement form; long-gap discharge radiated electromagnetic wave pulse time is detected simultaneously through the plurality of antennas; leader head position is positioned according to time difference of a signal arriving at different antennas; and furthermore, the long-gap discharge leader development speed can be calculated. The method can effectively improve the measurement precision of the discharge leader development speed, and resolution reaches the level of 0.1 ns.

The present disclosure provides a method and a system for estimating the 3D head position of a driver in a vehicle. The method includes capturing an image of the driver and identifying an area of ​​interest focused on the driver's head within the image. Furthermore, a virtual camera perspective is created by generating a cropped image centered on the head position. The true coordinates of the head in the original image are then transformed to align with the perspective of the virtual camera. This alignment ensures that the coordinates in the virtual camera perspective accurately correspond to the driver's head position. Finally, a pre-trained estimation model is applied to the transformed, cropped image to determine the 3D position of the driver's head, enabling accurate, real-time monitoring of the driver's orientation and position.The method improves the accuracy of the estimation by standardizing head positioning in relation to the camera viewpoint, which is a basic requirement for driver assistance and safety systems.

The application relates to the technical field of eye movement instruments, and discloses an autism eye movement track recognition instrument, which comprises an instrument base plate, a playing device is fixedly installed at one end of the instrument base plate, a head limiting mechanism is rotationally assembled at the other end of the instrument base plate, the playing device is used for playing materials, and an eye movement tracking camera for collecting the eye picture of a patient when the patient watches the materials is hiddenly installed on the playing device. The autism eye movement track recognition instrument limits the head position of the patient through the swingable head limiting mechanism, the swing of the head of the patient can reduce the uncomfortable feeling, the eye movement tracking camera is driven to move synchronously through a power transmission assembly, the eyes of the patient can be kept facing the camera during the test process, the eyes of the patient are prevented from deviating from the shooting range of the camera, and the eye movement tracking camera is prevented from moving and lagging behind when the head of the patient swings, so that the shooting of the eyes is not delayed, and the accuracy of collecting the eye movement track of the patient is ensured.

This utility model discloses an ironing device with switchable head posture, belonging to the field of garment ironing technology. Existing handheld ironing devices require two hands to operate when changing working postures. This utility model addresses this by configuring an angle limiting structure between the head and the handle. This angle limiting structure restricts the head's rotation between a first position and a second position. An elastic force is also applied to the head to hold it in the first or second position. During the latter part of the head's rotation in one direction between the first and second positions, this elastic force assists the head in rotating to the first or second position. To change the head posture, the handle can be grasped, and the head can be pressed against an external object such as clothing or an ironing board to apply external force. This external force generates torque on the head, causing it to rotate and, with the help of the elastic force, rotate into and maintain the corresponding position. Therefore, only one hand is needed to switch the head posture, improving convenience.

The application relates to a mixed reality office scene bad sitting posture correction method and device, equipment and medium, which are suitable for a mixed reality head-mounted device. The method continuously acquires current spatial posture information of a user's head and shoulders, calculates head position offset, left shoulder position offset, right shoulder position offset and head angle offset based on the current spatial posture information and a reference posture model, and judges whether the user is in an abnormal posture state according to each offset and a corresponding threshold value. When the abnormal posture state lasts for more than a preset time length, the mixed reality head-mounted device is controlled to visually modulate display content to prompt the user to adjust the posture. The application can improve the accuracy of bad sitting posture recognition and reduce the interference on the user's office process.

This utility model discloses a head positioning device, including a forehead support device, a chin support device, and a positioning housing. The forehead support device is disposed above the positioning housing, and the chin support device is disposed below the positioning housing. The forehead support device has several forehead support members for supporting the forehead. The chin support device has a top support position for supporting the chin. When a facial photograph needs to be captured, the subject's chin rests on the top support position, and then the forehead rests on the forehead support members, thus keeping the entire head in a relatively static state for a short period of time, facilitating facial image acquisition by the facial imaging device. This utility model achieves stable head positioning using only the top support position and forehead support members. Compared with previous head positioning devices, this utility model is more user-friendly and can achieve better head positioning.
