A spring is arranged at the top of the bottom plate, a foot pocket is arranged at the top of the protective pad, an adjusting device is arranged on one side of the bottom plate, a moving device is arranged at the top of the protective pad, the adjusting device comprises a rectangular plate, a sliding groove is formed in the top of the bottom plate, and when the adjusting device is used, the rectangular plate is controlled to move in the sliding groove, so that the rectangular plate can move in the sliding groove. And when the rotating plate is controlled to be parallel to the bottom plate, the compressed distance of the spring is changed, so that the force of the auxiliary support can be well controlled, and the force of extruding the rotating plate by the spring can be controlled according to different rehabilitation stages.

The invention discloses a watch heart rate monitoring method and device based on TEC temperature control, and solves the problem of inaccurate heart rate monitoring caused by the fact that the influence of temperature on a photoelectric sensor is not considered when a smart watch photoelectric measurement method is used for measuring the heart rate in the prior art. Comprising the following steps: acquiring the surface temperature of LED lamp beads at the bottom of the watch or the ambient temperature in real time; according to the target temperature range and the current temperature value, the TEC working mode is adjusted based on a preset temperature control algorithm; continuously detecting the temperature of the LED lamp bead, and dynamically adjusting the working power of the TEC according to the temperature change trend; after the temperature of the watch is stabilized within the target temperature range, photoelectric signals are collected for heart rate monitoring. The light source temperature can be stabilized in the optimal working temperature interval, and the accuracy of heart rate measurement is improved.

The present invention provides a kind of plasma processing device, the purpose is to control the power of the power with the bandwidth realized by multiple carriers after pulse modulation with high precision.The device includes the power supply unit that can generate the power with bandwidth, the power generated by power supply unit is implemented pulse modulation so that it has high level power and low level power, and, the pulse on time determined by setting pulse frequency and setting duty cycle has the power variation period of the power with bandwidth is long.

The application discloses a kind of radio frequency signal source output power control method, the method includes: the output power range of standard radio frequency signal source and the numerical control attenuation range of numerical control attenuator are divided to obtain multiple control regions, the boundary point of each control region corresponds an output power, a frequency and a numerical control attenuation quantity;Each control region is constructed standard corresponding relationship based on the numerical control attenuation quantity corresponding to the voltage control attenuator;Based on the standard corresponding relationship, target frequency and target power, control the radio frequency signal source to be controlled, can accurately control the power required by radio frequency signal source output, avoid the larger error of output power.

The automatic aggregate shaping device comprises a motor and a crusher, the crusher comprises a crushing barrel and a driving shaft, a cover plate is arranged at the top of the crushing barrel, a discharging hopper is arranged at the bottom of the crushing barrel, the driving shaft is rotationally arranged in the crushing barrel through a bearing, the motor is connected with the driving shaft in a driving mode, and hammer discs are arranged on the driving shaft at equal intervals. According to the utility model, the motor is adopted to drive the driving shaft to rotate, the hammer disc and the hammer head on the driving shaft are driven to rotate, aggregate in the crushing cylinder is rapidly hammered, and the rotating shaft continuously rotates, so that the aggregate in the crushing cylinder can be fully acted to ensure the uniformity of crushed stones, and meanwhile, the crushing efficiency is improved. The high-definition cameras are arranged on the two sides of the feeding hopper respectively, so that the volume of input aggregate can be monitored, the power of the driving motor is controlled, the crushing effect is guaranteed, the state and the shape of the aggregate in the crushing barrel can be monitored, and therefore the particle size qualification rate of the aggregate particles is judged to determine whether shaping of the aggregate particles is qualified or not.
