A gas supply device for the feed heater and thermal oil furnace of a naphtha hydrogenation unit is characterized by: a valve assembly installed on the inlet pipeline of the fuel gas separator; the inlet pipeline of the valve assembly is divided into two lines, one for natural gas and the other for the main fuel gas pipeline; the outlet pipeline of the fuel gas separator is also divided into two lines, one connected to the feed heater and the other connected to the thermal oil furnace. This invention, by adding a natural gas pipeline, switches the gas supply to the feed heater and thermal oil furnace to natural gas when flue gas indicators are abnormal, avoiding abnormal flue gas from the heater due to changes in fuel gas composition. This ensures stable operation of the unit and compliant flue gas emissions, meeting environmental protection requirements and reducing environmental risks for enterprises. It largely maintains the original structure of existing equipment, requiring no major modifications, and features low modification costs and high economic benefits.

This invention relates to the field of robotics and provides an adaptive robotic hand, comprising: a connecting arm connected to a predetermined position on a machine, wherein at least three gripping claws are rotatably connected to the front end of the connecting arm; a control component disposed inside the connecting arm to control the state of the gripping claws; a drive component for controlling the state of the control component is fixed on the connecting arm; and the gripping claws abut against the control component under the action of a torsion spring. By providing an automatic gripping pressure detection device, this invention ensures that whether to grip a workpiece can be determined by detecting the gripping pressure, thus adapting to the gripping requirements of different parts.

This application relates to a nitrogen humidifier, comprising a first housing, a connecting member, an air inlet pipe, a liquid inlet pipe, a second housing, a flow restrictor, and a connector. The connecting member is disposed at a first opening of the first housing and has a first air passage, an air inlet passage, and a liquid inlet passage, which are respectively connected to an external controlled air source and a liquid source. The air inlet pipe and the liquid inlet pipe respectively introduce gas and liquid into a first accommodating space for premixing. The first air passage connects to a second accommodating space of the second housing, where the flow restrictor is disposed. The flow restrictor agitates the ejected mixed airflow to achieve secondary mixing. The connector is disposed at a third opening of the second housing to exhaust the mixed gas. This nitrogen humidifier, through independent gas and liquid supply and a two-stage mixing design, effectively improves humidification efficiency and humidity stability, solving the problems of low mixing efficiency and poor humidity control in existing technologies, and is suitable for high-precision process requirements.

This invention belongs to the field of elevator light curtain technology and discloses an elevator light curtain with door opening and closing warning function. It includes a light curtain housing and positioning frames fixed at both ends. A groove is formed on the left side of the light curtain housing, and the light curtain body is connected inside the groove. Warning LEDs are installed on both sides of the light curtain body. A movable frame is fitted around the outside of the light curtain body. Limiting grooves are formed on the front and rear sides of the light curtain housing, and the movable frame slides in cooperation with the limiting grooves. This elevator light curtain with door opening and closing warning function completely changes the traditional "passive response" safety protection mode of light curtains through the design of multiple arrays of dual-color warning LEDs, constructing an active and efficient warning system. During the elevator door closing process, the high brightness and wide warning range of the dual-color flashing lights can clearly remind the elderly and children who move slowly, and can also effectively attract the attention of passengers focused on electronic devices, avoiding collisions or pinching accidents caused by delayed reaction.

This application relates to a case file review method, apparatus, computer equipment, computer-readable storage medium, and computer program product. The method is executed by a review model and includes: acquiring a case file to be reviewed; extracting case file keywords from the case file; determining the review type of the case file based on the case file keywords; searching for review prompt words corresponding to the case file in a prompt word rule base according to the review type and case file keywords, and combining the review prompt words corresponding to the case file to be reviewed to obtain a review prompt word chain; and reviewing the content in the case file to be reviewed sequentially according to the review prompt word chain to obtain a review result. This method enables efficient and accurate case file review.

This invention relates to a secure cross-network data transmission device, belonging to the field of data transmission technology, and solves the technical problems of high cost, low efficiency, and insufficient transmission stability and security in existing cross-network data transmission. The solution is: a secure cross-network data transmission device for unidirectional data transmission from an intranet to an extranet, comprising: a rectangular shell; a high-definition display module located on the front inner wall of the shell, used to display generated QR code images in high definition; a data receiving module located inside the shell, used for unidirectional data reception; and an audio module located on one side wall and bottom inside the shell, used to provide sound output. Compared with existing technologies, this invention has advantages such as unidirectional transmission, high security, simple deployment and operation, low cost, high transmission efficiency, strong stability, and high accuracy.

This application relates to a low-cost, high-reliability single-event lock-up protection method and circuit. When a device encounters a single-event lock-up, the method automatically cuts off power supply via hardware and delays restarting, while the FPGA records the event. If the single-event lock-up persists after several consecutive restarts, the FPGA outputs a signal to forcibly cut off power supply, thereby protecting downstream circuitry from single-event effects and preventing system malfunctions. This method utilizes hardware and software collaboration to avoid repeated system restarts that fail to remove the locked device from the lock-up state. It rationally optimizes single-event lock-up protection measures, achieving single-event lock-up protection for devices without single-event data or those sensitive to single-event lock-up. This saves testing time and enables highly reliable on-orbit applications of lock-up-sensitive devices.

This invention discloses an AI-powered holographic image adaptive enhancement system that adapts to network latency fluctuations, belonging to the field of communication and holographic imaging technology. By monitoring network latency, bandwidth, and packet loss rate in real time, this invention dynamically and adaptively adjusts the resolution, frame rate, data compression ratio, and transmission priority of the holographic image using AI algorithms. It is compatible with all network types, including 6G, 5G, WiFi 6 / 7, and Ethernet. When network conditions are good, it improves image quality; when network fluctuations occur, it prioritizes ensuring smooth interaction, achieving an optimal balance between image quality and latency. Simultaneously, it achieves multi-dimensional synchronous adaptation of holographic images, spatial audio, and interactive commands. This invention significantly avoids image stuttering, tearing, and blurring caused by network fluctuations, while reducing terminal computing power and power consumption, and can be widely adapted to various holographic interactive terminals.
