Abstract: A pressure measuring method, applied to a pressure measuring apparatus, comprising: measuring a first pressure sensing value when the pressure measuring apparatus operates at a first scan frequency and receives a first pressure; and measuring a second pressure sensing value when the pressure measuring apparatus operates a second scan frequency and receives the first pressure. The first pressure sensing value and the second pressure sensing value are different, and a change between the first pressure sensing value and the second pressure sensing value is according to a change between the first scan frequency and the second scan frequency. The first scan frequency and the second scan frequency are different. The pressure measuring method can further comprise a calibrating mechanism to compensate the sensed pressure. By this way, the pressure sensing value can be calibrated, to solve the issue that the pressure sensing values are affected by scan frequencies.

Abstract: A system for obstacle detection adapted to a self-guiding machine is provided. The system includes a controller, a linear light source and a light sensor. The linear light source and the light sensor are set apart at a distance. When the linear light source emits an indicator light being a vertical linear light projected onto a path the self-guiding machine travels toward, the light sensor senses the indicator light. The vertical linear light is segmented into a first segment projected to a ground and a second segment projected to a floating obstacle when the self-guiding machine approaches the floating obstacle with a height from the ground and the indicator light is projected to the floating obstacle, in which the second segment of the light sensed by the light sensor is determined as the floating obstacle in front of the self-guiding machine.

Abstract: An optical detection device includes a substrate, a housing, an optical modulating component, an optical sensor and a cover. The housing is disposed on the substrate and includes a first aperture. The housing is unvaried due to inspection standard or design requirement of the optical detection device. The optical modulating component is disposed on the housing and aligning with the first aperture. The optical sensor is disposed on the substrate and adapted to receive an optical signal passing through the optical modulating component and the first aperture. The cover is disposed on the housing to cover the first aperture. The cover is replaceable for attaching the cover varied for the inspection standard or the design requirement to the unvaried housing in response to a surface of the cover opposite to the housing matched and engaged with a light penetrating area on the optical navigation apparatus.
