  • Patent number: 9974248
    Abstract: A planter box for holding planting soil includes a box body having a bottom wall, a sidewall and an open top. An anti-clog drainage and irrigation pipe is mounted across and above the bottom wall. The pipe includes a water inflow and outflow opening formed at a lower portion and extending along the length of the pipe. Two flow-guiding plates extend from two longitudinal sides of the water inflow and outflow opening towards an interior of the pipe body to form two overflow troughs in the pipe. During rainy day, the pipe is used for drainage. During sunny days, water can be supplied to the pipe for irrigation. A method for soil drainage and irrigation is also disclosed.

  • Patent number: 7025789
    Abstract: The prosthesis device can have a pair of articular members adapted to be mounted onto adjoining bones, respectively, to replace a joint. The first and second articular members can have first and second bearing elements, respectively. The bearing elements can be formed to be capable of replacing at least a portion of the bone ends of the adjoining bones, respectively, and providing an articulation close to that of a natural joint. The bearing elements can be fixed to the respective bones through an initial implant fixation achieved by press-fit anchoring immediately after surgery and/or a secondary implant fixation established from bone-ingrowth.
