Abstract:
A baby carrier is provided. The baby carrier includes a body part, a pair of shoulder bands coupled to opposite sides of an upper portion of the body part, a waist band coupled to a lower portion of the body part, a load control unit which is coupled to the waist band and is changed to any one posture of a first posture and a second posture to switch a load-applied direction. A ratio of loads applied to the shoulder bands and the waist band is changed in response to the load control unit being changed from the one posture of the first posture and the second posture to the other posture of the first posture and the second posture.
Abstract:
A formaldehyde detecting apparatus includes a formaldehyde sensor configured to measure concentration of formaldehyde in air; a printed circuit board on which the formaldehyde sensor is disposed, the printed circuit board including a signal processor configured to process a signal output from the formaldehyde sensor; a fixing member disposed on the printed circuit board, the fixing member configured to fix the formaldehyde sensor, wherein the fixing member prevents the formaldehyde sensor from oscillating with respect to the printed circuit board by external vibration; and a power supply configured to supply a voltage capable of stabilizing an output signal to the signal processor.
Abstract:
