Abstract: This disclosure relates to methods, devices and systems for real-time recognition of restoration of spontaneous circulation (ROSC) in cardio-pulmonary resuscitation (CPR) process. Recognition mechanisms in both time domain and frequency domain are provided for the ROSC recognition, where the time-domain recognition logic may detect the ROSC by recognizing envelope features of sampled signals in the time domain, and the frequency-domain recognition logic may detect the ROSC by recognizing spectral peaks at different frequency points continuously or significant variations of amplitude of spectral peaks in the frequency spectrum.

Abstract: A display motherboard and a manufacturing method thereof are provided. The display motherboard includes a first substrate and a second substrate that are assembled, a plurality of mutually independent display devices located between the first substrate and the second substrate, a first seal, and a second seal. The first seal is provided in a peripheral area of the display motherboard, the second seal is provided in a cutting area of the display motherboard, the cutting area is located around each of the display devices, and the second seal surrounds at least one of the display devices.

Abstract: A substrate fixing carrier includes a supporting frame and a cooling plate. The supporting frame defines a hollow region and a supporting portion at an inner wall of the supporting frame. The cooling plate and the supporting frame are movable towards each other until the cooling plate is in the hollow region with edges of the cooling plate aligning with the supporting portion. When a rectangular to-be-evaporated substrate is placed in the hollow region with edges of the rectangular to-be-evaporated substrate between the supporting portion and the cooling plate, a distance between each edge of the cooling plate corresponding to each long side of the to-be-evaporated substrate and the supporting portion is greater than or equal to a thickness of the to-be-evaporated substrate, and a distance between each edge of the cooling plate corresponding to each short side of the to-be-evaporated substrate and the supporting portion is less than the thickness of the to-be-evaporated substrate.
