Abstract: One example blood pressure measurement device includes a body, a wrist strap, an airbag, an air supply and exhaust apparatus, a first sensor, and a second sensor. The airbag has an air cavity, and the airbag is connected to the body. The body includes a cavity, and the air supply and exhaust apparatus is disposed in the cavity. The air supply and exhaust apparatus includes an air intake path and an air exhaust path, and the air supply and exhaust apparatus communicates with the air cavity of the air bag. The first sensor is configured to measure an air pressure value in the air cavity. The second sensor is located on a same side of the wrist strap as the airbag, and is configured to measure a pulse wave signal.

Abstract: A blood pressure measuring device includes a main body and an airbag. An air supply and exhaust apparatus and a first air pressure sensor may be disposed in the cavity of the main body. The air supply and exhaust apparatus includes an air inlet passage and an air outlet passage. The air supply and exhaust apparatus is communicated with the air cavity through a first air passage. The first air pressure sensor includes a first air hole and a second air hole, and a pressure film is provided between the first air hole and the second air hole. A first vent hole is provided on the side wall of the main body. The first air hole may be communicated with the air cavity of the airbag through a second air passage, and the second air hole may be communicated with the first vent hole through a third air passage.

Abstract: A communications device includes an antenna including a radiator and a ground. A NFC circuit and the radiator are coupled at a first node; a non-NFC circuit and the radiator are coupled at a second node by using a non-NFC feeding path, the non-NFC feeding path includes two capacitors with different capacitances. The radiator forms a first part between the first node and the second node. The radiator includes a second part, one end of the second part is coupled to the ground, and the other end is connected to the first part. An electrical length of the second part is less than a quarter wavelength corresponding to a resonance frequency of a low frequency signal, and the electrical length of the second part is greater than an electrical length of the first part. The radiator includes a third part from the first node to an endpoint of the radiator.
