Abstract: A method of building upstream-and-downstream configuration of sensors includes determining two sets of geographic position data of a target sensor and a candidate sensor, obtaining pollution-associated periods according to pieces of flow field data, the sets of geographic position data and pieces of target sensing data of the target sensor to determine a pollution-associated period, calculating a correlation between target sensing data obtained by the target sensor during the pollution-associated period and candidate sensing data obtained by the candidate sensor during the associated air pollution period to obtain sensor correlations, and determining the target sensor and the candidate sensor having a upstream-and-downstream relationship with the candidate sensor being used as a satellite sensor of the target sensor when a quantity ratio of sensor correlations being larger than or equal to a correlation threshold is larger than or equal to a default ratio.

Abstract: A suspension particle sensing apparatus includes a first flow channel, a suspension particle concentration sensor and a suspension particle filtering assembly. The first flow channel has a first entrance and a first exit. The suspension particle concentration sensor is disposed in the first flow channel, and is located between the first entrance and the first exit. The suspension particle filtering assembly is disposed at the first entrance, and includes a casing and a suspension particle filtering structure. The casing has a first opening and a second opening. The first opening is communicated with the first entrance of the first flow channel. The suspension particle filtering structure covers the second opening.

Abstract: A particle sensing device, configured to detect a particulate concentration in a fluid, includes a detecting channel, a sensing space, a light source and a sensor. The detecting channel is configured for the fluid to flow therethrough. The sensing space is located on one side of the detecting channel and connected to the detecting channel, and the sensing space is surrounded by a surrounding wall. The light source and the sensing space are located on opposite sides of the detecting channel, and the light source is configured to emit light towards the detecting channel. The light is configured to hit at least one particle in the fluid. The sensor is disposed on an inner surface of the surrounding wall, and the sensor is configured to detect a scattered light energy generated when the light hits the particle. The sensor is a distance apart from the detecting channel.

Abstract: An automatic adjustable supporting equipment, including a supporting band, an adjusting device, and a controller, is provided. The supporting band wraps around a limb of a user. The adjusting device is disposed on the supporting band, and includes an actuating mechanism and an accelerometer. The actuating mechanism is configured to adjust a pressure applied on the limb by the supporting band. The accelerometer is configured to detect an acceleration value. The controller is coupled to adjusting device, and is configured to drive the actuating mechanism to adjust the pressure to a preset pressure value according to the acceleration value.
