  • Publication number: 20240362967
    Abstract: An automated sortation and dispensing system (1000) includes a frame (100) defining a cavity (101) in which objects (109) are stacked, a lever axis defined by a transverse rod (104) fixed in the frame, a drive unit (103) pivotally coupled to the transverse rod, a sorter (102) extending upward from and rotatably driven by the drive unit and including upper and lower helical slots (1022, 1025) for carrying the objects, and a shock absorber (105) engageable with an upper end of the sorter. When the drive unit is activated, the drive unit drives the sorter to spin. If a force is exerted on the sorter by the objects, the drive unit pivots downward, and the sorter tilts sideways to absorb the force and moves back by a rebound force of the shock absorber when the force is released.

  • Patent number: 9665209
    Abstract: The present application is directed to a pointing device and a method for interacting with touch-sensitive devices. The pointing device includes a supporting member, first and second contact points fixed on the supporting member and adapted to be in contact with a touch-sensitive layer in a default state, and at least one movable contact point mounted on the supporting member and movable from the default state to a fully depressed state adjacent to the second contact point to form a combined touch area on the touch-sensitive layer having an offset center that is offset from a center of the second contact point so that the second touch point is shifted to an offset position in alignment with the offset center.

  • Patent number: 9489059
    Abstract: The present application is directed to a pointing device and a method for interacting with touch-sensitive devices. The pointing device includes a base; a housing configured to cover a portion of the base; a cavity formed between the housing and the portion of the base; a sliding member; a supporting member; a biasing member situated between the sliding member and the supporting member; a first contact point provided on the sliding member and configured to contact a screen of the touch-sensitive device when the pointing device is placed on the screen; and a second contact point provided on the supporting member and configured to contact the screen when the pointing device is placed on the screen; wherein the first contact point slides on the screen relative to the second contact point via the engagement of the housing and the sliding member when the housing moves towards the screen.
