Abstract: A structured perforated plastic sheet includes a plastic sheet body having bottom ribs in a bottom layer, middle ribs in a middle layer, and top ribs in a top layer. The top ribs are interconnected to define a top hole. The middle ribs divide the top hole into multiple middle holes. The bottom ribs divide each middle hole into multiple bottom holes. Each of the top, middle and bottom ribs has a top wall and two side walls extending downwardly from two opposite sides of the top wall. The side walls of the top and middle walls are deflected in a plane of the top walls of the bottom ribs.

Abstract: A plant growing device includes an envelope and a plant growing medium. The envelope is made of a sheet material and has substantially planar first and second walls, a surrounding wall connected between the first and second walls, and a plurality of openings formed in the second wall and adapted to permit extension of plants. The plant growing medium is enclosed by the envelope, and includes a water-absorptive material selected from a polymeric foam, saw dust, charcoal, soil, sand, wood pulp, polymeric fibrous substances, and natural fiber materials.

Abstract: A top sheet includes a sheet body having a flat liquid pervious base wall with first and second surfaces that are opposite to each other in a normal direction relative to the sheet body. The base wall has front and rear edges that are opposite to each other in a longitudinal direction. The sheet body further has a plurality of protrusions that protrude from the first surface of the base wall and that are distributed along the longitudinal direction as well as a widthwise direction which is transverse to the longitudinal direction. The protrusions are arranged in such a manner to form a plurality of open fluid channels thereamong. The fluid channels extend from the front edge to the rear edge of the base wall, and have dimensions in the normal and widthwise directions sufficient to provide capillary action.

Abstract: A projector has a housing, a screen installed in the front of the housing for displaying an image, a projecting modole installed in the housing, a control module, and at least One detector. The projecting module includes an image generator that converts image signals into an image with a corresponding resolution, and a projecting lens set used for projecting the image onto the back of the screen. When the control module receives a focus-changing signal, the control module will change the focus of the projecting lens set to adjust the size of the image. The detector is installed on the screen for sensing the image on the screen. When the control module receives the focus-changing signal, the control module will continuously change the focus of the projecting lens set to adjust the size of the image until the detector senses the edge of the image.
