  • Publication number: 20240009084
    Abstract: The present specification describes a medicine dispensing system for automatically dispensing medication at a predetermined time. The system includes a cartridge that carries a strip of medicine pouches. When the cartridge is dropped into a dispensing unit, it automatically aligns with the dispensing unit without requiring any installation work from the user. The automatic alignment is enabled because of self-aligning features manufactured in the cartridge housing.

  • Patent number: 11097434
    Abstract: An ergonomically designed, auto-retracting utility knife that can safely remain in the user's hand while performing non cutting tasks.

  • Patent number: 6371404
    Abstract: A bobbin for an electrical coil having a width that is small with respect to its depth. The bobbin is constructed from two identical halves, each having one generally flat flange and a web portion defining a latching feature, a locking feature and a core window centrally located in the flange. The mating surfaces of the two bobbin halves are defined along the distal ends of the web portions such that each half includes one complete flange and core window. The mating surfaces are also configured such as to prevent the fine coil wire from slipping between the mating surfaces of the two bobbin halves as the coil is being wound. The latching features of one bobbin half slidingly engage the latching features of the other bobbin half such that the two bobbin halves are held together. The locking features of the two bobbin halves also engage to prevent unintentional longitudinal movement between the two bobbin halves prior to winding the coil wire on the bobbin.
