An electric curtain mainly utilizes a covering sheet furled at an upper limit position, which simultaneously impels an actuating member of a zero device to relatively cooperate with a sensor of the zero device, so that the covering sheet would not continue operating and a counter in the zero device would recount once a processing unit of a controlling device receives a signal from the sensor. Thus, the processing unit would drive the counter to recount in every following drop of the covering sheet to accurately control the suspending position without incurring an accumulative counting error and increase an operative convenience.

A crawling insect barrier in which the combination of elements functions as a natural device to prevent ants or other crawling insects from accessing a table, cabinet, storage bin, structure, or any area wherein crawling insect infestation is undesirable. In one embodiment, a feather ring comprises a string (elastic or fixed length) to which natural feathers of various sizes and shapes are fastened, to thereby create a natural barrier or boundary that prevents crawling insects from crossing, and thus inhibiting the insects' ability to carry food, mark a path, build a nest, or infest an area. In another embodiment, a band or strap is used as the underlying surface on which the feathers are attached. If the string, band or strap is not elastic, the crawling insect barrier can be attached with adhesive or some other conventional fastener.
