Abstract: A serial interface-Ethernet interface data conversion apparatus includes a printed circuit board, a microcontroller controlling operations on the printed circuit board and a power input connection for providing power to components on the printed circuit board. One or more serial interface is provided along with an Ethernet interface. The microcontroller is programmed to convert a signal input received via the one or more serial interface to a signal output via one of the Ethernet interface and to convert a signal input received via the Ethernet interface to a signal output via the one or more serial interface.

Abstract: A thermal scale radio frequency label which includes a top layer of thermal paper of 20-60 lb weight with an RF antenna mounted on the thermal paper. The RF antenna includes a single turn inductor coil having a width of not less than 5 mm and not more than 13 mm. The inductor coil has a thickness in the range of 30-60 um and covers an area of at least 55×49 mm. A capacitative layer is provided having a thickness in the range of 30-60 um. A dielectric layer is positioned between the capacitative layer and the inductor coil. A plurality of electrical connections are provided between the capacitative layer and the inductor coil. The electrical connections are capable of being deactivated by RF energy.
