Through a plurality of consecutive frames, a display controller produces a multi-gradation image on a display device formed by a plurality of binary-state pixels in an array. The display controller includes an image memory for providing each of the pixels with gradation data. A waveform pattern selector outputs a waveform pattern selecting signal for causing a waveform pattern memory to provide any two adjacent pixels with two different sets of waveform pattern signals. The plurality of consecutive frames are operated at a fixed frame rate, which is set high enough for preventing visual disturbances.

The invention relates to a light-emitting diode sleep regularizer, which is characterized in that it includes a base that matches the neck of a human body, at least one LED component arranged on the base, a control circuit, and a control circuit connected between the control circuit and the LED component. switchgear. The sleep regularizer uses light waves to stimulate the nervous tissue in the light-sensitive parts of the human body's high spinal cord and hypothalamus, thereby correcting abnormal sleep patterns. At the same time, the light waves penetrate the back and side skin of the head and neck without Cause visual fatigue so as to avoid vision damage induced by strong light effect. At the same time, the product is battery-driven, easy to carry, and its structural design matches the shape of the human neck, allowing users to wear it freely in daily life.

The invention relates to a local coil positioning method, a magnetic resonance system and a computer readable storage medium. The local coil positioning method comprises the steps of acquiring first position information based on relative position information between a local coil and an imaging space of the magnetic resonance system; displaying a mark representing the local coil on an operation interface according to the first position information; receiving the mark selected on the operation interface; and moving the local coil corresponding to the selected mark to the imaging space. Accordingto the invention, the distance between the local coil and the imaging space is acquired, and thus the local coil is moved to the imaging space, so that the accuracy is greatly improved. In addition,the mark corresponding to the local coil can also be displayed on the operation interface, and a user can select the mark through the operation interface so as to realize automatic follow-up operations of the magnetic resonance system, so that the operation time is greatly reduced, requirements for relevant operating experience of technicians are lowered, and visual impairments for patients and technicians are avoided.

The invention discloses a welding device for a three-gear and four-gear shifting fork shaft. The welding device comprises a sealed welding box, a shaft lever feed device, a gear shifting guide block feed device, a vacuumizing device, a controller and a drive motor, wherein a welding die, an arc welding machine and a moving mechanism used for controlling the arc welding machine to move are arranged in the welding box, the shaft lever feed device and the gear shifting guide block feed device are communicated with the welding box, the vacuumizing device and the controller are arranged on the welding box, an observation window is arranged on the operating face of the welding box, rolling curtain cloth is arranged above the observation window, and two operation gloves are arranged below the observation window. The drive motor is used for driving the rolling curtain cloth to be rolled down to seal the observation window before welding and to be rolled up after welding, and electrically connected with the controller. The welding device has the advantages that an operator places a shaft lever and a gear shifting guide block to the designed positions on the welding die by means of the operation gloves, then the controller controls the drive motor to roll the rolling curtain cloth down to seal the observation window, under the vacuum condition, the connecting portion of the shaft lever and the gear shifting guide block is welded, the situation that the high-temperature part of the shaft lever is oxidized in the welding process is avoided, and injuries to eyesight of the operator in the welding process can be prevented.

An intra-regional vehicle driving status information sharing informing platform system comprises at least two mobile stations which are arranged on different vehicles within the region and with a driving status information sharing function. Each of the mobile stations comprises an information-sending module used for sending self-driving-status information, an information-receiving module used for receiving driving status information of other vehicles within the region, an information-processing module used for expressing and processing vehicle driving status information and a terminal display used for displaying a processing result of the information-processing module, wherein the information-sending module, the information-receiving module and the terminal display are respectively connected with the information-processing module. According to the intra-regional vehicle driving status information sharing informing platform system, transmission modes such as electromagnetic wave are used, vehicle driving status information transmission and sharing are conducted among the mobile stations, visual disorder of drivers within the region can be overcome and driving status information of other vehicles out of sight can be acquired, and thus the problem that vehicle collision is prone to occurring at the corner or at the crossroads and the potential safety hazard of out of sight when overtaking is conducted are effectively resolved.
