A method for determining a level of degradation of a road marking is executed by a determination unit. The method includes generating a plurality of reference images by an image capturing device photographing a reference road marking with a plurality of shutter speeds. The reference images are stored in a database. The method further includes generating an image by the image capturing device photographing an examined road marking according to a selected shutter speed, retrieving one of the reference data from the database that has the same shutter speed as the examined road marking by a processor, and performing a difference determination procedure between the retrieved reference data and the examined data by the processor, and outputting a determined result of the level of degradation of the examined road marking by the processor. As such, accurate determination on the level of degradation of the examined road marking can be achieved.

Method for determining the level of degradation of a road marking

A heat ventilating chair includes a backrest unit, a seat unit, and a connecting unit connecting the backrest unit to the seat unit. One of the backrest unit and the seat unit includes a hollow member having an air pump, a pressure valve, and a channel that communicates fluidly the air pump and the pressure valve. The connecting unit is connected between the air pump and the other one of the backrest unit and the seat unit. The connecting unit drives the air pump to expel hot air in the channel to the ambient via the pressure valve when the backrest unit is forced to incline rearward. The connecting unit drives the air pump to draw ambient cool air into the channel via the pressure valve when the backrest unit is restored from a rearwardly inclined state.
