Abstract: A luminometer (400) includes a light detector (630) configured to sense photons (135). The luminometer (400) includes an analog circuit (915a) configured to provide an analog signal (965) based on the photons (135) emitted from assay reactions over a time period and a counter circuit (915b) configured to provide a photon count (970) based on the photons (135) emitted from the assay reactions over the time period. The luminometer (400) includes a luminometer controller (905) configured to, in response to an analog signal value of the analog signal (965) being greater than a predetermined value, determine and report a measurement value of the photons (135) emitted from the assay reactions over the time period based on the analog signal value of the analog signal (965) and a linear function (1010). Optionally, the linear function (1010) is derived from a relationship between the analog signal (965) and the photon count (970).

Abstract: A method of stabilizing data of digital signals is provided. The method includes steps of: setting a boundary coefficient; reading a piece of digital data; defining a value of the piece of digital data as a center value; outputting the value of the piece of digital data; reading a next piece of digital data; subtracting a value of the next piece of digital data from the previously outputted value to obtain a positive difference or a negative difference; and determining whether or not an absolute value of the positive or negative difference is larger than the boundary coefficient, if not, outputting the center value, if yes, updating the center value such that the updated center value is equal to the value of the next piece of digital data, and outputting the updated center value.

Abstract: A method can be applied to a terminal provided with a light sensor to determine a screen light intensity value. The method can include: obtaining a screen light intensity detection value detected by the light sensor, and obtaining a current environment temperature when the light sensor detects the screen light intensity detection value; determining a light intensity calibration coefficient corresponding to a value of the current environment temperature based on a corresponding relationship between a temperature and the light intensity calibration coefficient; and determining the screen light intensity value of the terminal based on the determined light intensity calibration coefficient and the screen light intensity detection value.
