  • Publication number: 20200039599
    Abstract: A balancing transporter is provided to mitigate occurrence of undesired sudden turning and falling of a user by virtue of various mechanisms that control the source/cause of mistakes and implement post-mistake remedies. Two adjusting members are operated by the user for turning control in a manner that interference between operations on the adjusting members and on handles is prevented. Maximum allowance of difference between wheel speeds is introduced to prevent sudden turns due to inappropriate operation. A rotational interlock unit mechanically enables the adjusting members to rotate in opposite directions to prevent sudden turns. Shock absorption and balance compensation mechanisms are introduced to keep the balancing transporter from tilting.

  • Patent number: 10518435
    Abstract: A feeding system with numerically adjustable pneumatic cylinder speeds includes: a frame; an X-axis pneumatic cylinder; a Z-axis pneumatic cylinder; a feeding table connected to the pneumatic cylinders in order to be driven into motion in the X- and Z-axis directions; an X-axis detection module; a Z-axis detection module; a microcomputer; and a display screen electrically connected to the microcomputer. The microcomputer uses each detection module to determine the time interval between the instant at which the piston rod of the corresponding pneumatic cylinder passes the corresponding starting point and a subsequent instant at which the same piston rod passes the corresponding endpoint. The time intervals thus determined are defined as a duration of X-axis forward movement and a duration of Z-axis forward movement respectively. Both durations are displayed on the display screen.
