  • Device and method for positioning based on heterogeneous networks
    Patent number: 11982756
    Abstract: A method, implemented by a computer, for determining a position of a personal mobility device (PMD) comprises: estimating a position of a PMD based on a first wireless signal; determining whether the PMD is within an intermediate area between a first area and a second area, based on an estimated position of the PMD; determining whether the PMD moves to the second area, by using both the first wireless signal and a second wireless signal; and determining position of the PMD by using any one of the first wireless signal and the second wireless signal based on a movement of the PMD to the second area.

  • Multi-axial force sensor and grasper for sensing multi-axial force using the same
    Patent number: 9970836
    Abstract: Disclosed are a multi-axial force sensor capable of measuring multi-axial force and a grasper for sensing multi-axial force using the same. The multi-axial force sensor includes: a first operating section which includes a first member, and a first protrusion module formed protruding from one side of the first member; an elastic section which is formed at one end of the first member; a second operating section which includes a second member formed with one end to face one end of the first member with the elastic section therebetween, and a second protrusion module formed protruding from one side of the second member to face the first protrusion module; and an electrode section which is formed in the first protrusion module. With this, there is provided a force sensor capable of precisely measuring force through a simple structure.
