Systems and methods of passive and active scanning of WLAN-enabled access points to estimate position of a WLAN positioning device. The device comprises a patterned electrically-conductive layer associated with an active element of the electronic device. The dispensing mechanism includes a graduated scale corresponding to each of the index holes to provide a standard setting for the feeder which can be utilized by an animal producer to supply of feed flow at a given stage in the animal’s life cycle to obtain a desired growth rate. In one embodiment, a release sheet attached to the carrier sheet is used to hold the carrier sheet and attached rub-on transfer art in position over a fingernail, facilitating placement and transfer.
