The invention discloses an upper limb fixing frame for newborns. The structure includes a movable device, a fixing belt, a fixing frame and an air vent. , the air vent runs through the fixed frame, and there are two fixed belts, and the fixed belt wraps the fixed frame. The beneficial effect of the present invention is that the connecting rod is manually driven to move, so that the connecting shaft rotates around the fixed shaft so that the fingers are properly bent, and The air thrust generated by the movement of the push block in the sealed cavity is used to control the expansion or degassing of the air bag, and to realize the control of the bending degree when the finger holder is bent, avoiding the damage of the muscle tissue caused by the finger bending angle being too large, and ensuring no damage Muscle tissue can move without loss of physiological function.

The invention provides a transmitter comprising two (or more) phase locked loops controlling respective oscillators, and implementing different phase modulation. Multiple phases are derived from the respective oscillators, and an edge rotator forms an output signal from a combination of the phases. The oscillators can operate at different frequencies, neither of which is an integer multiple of the other, whereas the output signals of the multiplexers of the first and second phase locked loops are closer in frequency and can be the same. This reduces the problem of pulling, with a circuit that can be implemented with low power and area and with the versatility of being digitally intensive.

The invention belongs to the technical field of auto glass compressive strength detection, and discloses a compressive strength detection device, system and method for auto glass detection.
