Abstract: The disclosure relates to an oximeter, including a blood oxygen collecting unit that has a first light emitting unit emitting a red light, a second light emitting unit emitting an infrared light, and a light receiving sensor receiving the red light emitted by the first light emitting unit and not absorbed by a human body and the infrared light emitted by the second light emitting unit and not absorbed by the human body, and converting them into an electrical signal, a storage unit that stores measurement data and/or a power-on startup screen, the power-on startup screen including the last measurement result of a blood oxygen saturation and/or previous measurement results of the blood oxygen saturation, a power-on button that is for power-on startup, a microprocessor that calculates a blood oxygen saturation of the human body based on the electrical signal detected by the light receiving sensor.

Abstract: This application discloses a board, an electronic device, and a manufacturing method, and pertains to the field of bare die package technologies. The board includes a PCB assembly, a bare die, a reinforcing frame, a heat sink, and fasteners. Both the bare die and the reinforcing frame are located on a surface of the PCB assembly, the bare die is located in the reinforcing frame, and the reinforcing frame is fixedly connected to the PCB assembly by using the fastener. The heat sink is located on a surface of the bare die that is away from the PCB assembly, and the heat sink is fixedly connected to the reinforcing frame by using the fastener.

Abstract: A digital pulse oximeter with automatic orientation change function, comprising a housing that is configured to clamp a human finger being tested, a display window disposed at outside of and atop the housing, a circuit being disposed within the housing for calculating and analyzing the tested signals, and displaying them in the display window atop the housing via a display, wherein the said circuit has only one control key disposed on the housing, the said circuit allowing the display contents of the display to be always oriented properly for easy reading by connecting with one two-axis or three-axis accelerometer. The digital pulse oximeter of the present invention is featured with small size and convenient operation and can shift from one function to another using only one control key in conjunction with the interface display, thereby increasing the functions of small-sized pulse oximeters.
