You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. For decreases in temperature, the result is negative.
Method for capacitive compensation of laser cutting systems against ambient temperature changes
The present application relates to the technical field of laser cutting, and specifically relates to a method for capacitive compensation of a laser cutting system for environmental temperature change. The method comprises the following steps: 1) initializing the position of a laser cutting head, placing the laser cutting head in a temperature box, collecting multiple sets of temperature values and corresponding capacitive values by changing the temperature, and obtaining a temperature value-capacitive value relationship curve; 2) testing the temperature value-capacitive value relationship curve by changing different conditions; 3) calculating the slope of the temperature value-capacitive value relationship curve in different temperature intervals; 4) performing capacitive calibration in a conventional environment and recording the temperature value at the time of calibration; and 5) compensating the capacitive value by using the slope of the relationship curve and the calibration temperature value when the temperature changes. The present application solves the problem of capacitive value increase or decrease caused by environmental temperature change through capacitive compensation, ensures that the cutting head maintains a stable height when following the cutting, and thus achieves the expected cutting effect.

Cooling device suitable for human body
PCT designated stageWO2026040016A1Domestic cooling apparatusHeat storage plantsHuman bodyNetwork structure
A cooling device suitable for a human body. The cooling device comprises a phase-change composite material and an outer coating material, wherein the phase-change composite material is packaged inside the outer coating material. During a heat absorption and cooling process, the phase-change composite material is converted into a gel phase from a solid phase. The phase-change composite material mainly comprises a phase-change material and a gelling agent, wherein the phase-change material is an organic phase-change material, and has a phase-change temperature of 2-38°C; and the gelling agent mainly comprises two chain segments: one being a chain segment which is miscible with the phase-change material, and the other one being a chain segment which spontaneously forms physical crosslinking by means of non-covalent bond interaction. The gelling agent and the phase-change material mutually construct a three-dimensional network structure to obtain the phase-change composite material. When filling a cooling device, the phase-change composite material and the gelling agent are firstly heated and melted, then cooled to the phase-change temperature and the gelation temperature or higher, and packaged to obtain the cooling device. The cooling device has the advantages of a short curing time, a long cooling duration, good safety performance, etc.
