  • Patent number: 11022420
    Abstract: A flatness sensing device includes a pressure sensing unit and a controller. The pressure sensing unit includes a plate portion, and a pressure sensor fixed and exposed at an edge of the plate portion. A sensing surface of the pressure sensor is flush with the bottom surface of the plate portion. The pressure sensor senses a pressure or lack of pressure of an object to be tested when it touches the object to be tested. The controller receives the pressure value output from the pressure sensor and determines a flatness of the object to be tested, the controller can issue an alarm on finding non-flatness and cause the degree of flatness to be displayed to a user.

  • Patent number: 10823628
    Abstract: A device to sense degree of twist in a screwdriver and the magnitude of force applied includes a contacting portion, a deformation portion, a sensing portion, and a processor. The contacting portion receives a grip and twist pressure through the deformation portion which is tiltedly fixed to the contacting portion. The deformation portion carries the sensing portion and elastically deforms under the force and/or the torsion. The sensing portion detects a deformation of the deformation portion and generates a corresponding electrical signal. The processor receives the signal and determines the values of the twist caused and the force applied.
