摘要:
An RFID label with embedded tag is passed through an RFID antenna in a printer system, where the RFID antenna allows a roll of such labels to pass in close proximity to the antenna and still allow each individual RFID tag to be read and/or programmed. The RFID antenna has a rectangular RF field spreader in contact with a triangular divergent RF conductor with an RF source point at the point. Ground planes are located on either side of the antenna. In another embodiment, the printer system extracts or parses bar code commands from a data stream and passes the commands to both a printer and an RFID reader to print the image and program the tag with the bar code information.

摘要:
An RFID system, such as an RFID printer system, is used to create an RFID performance profile by interrogating an RFID tag at a first position starting at a minimum RF power and increasing the RF power until a successful interrogation is obtained. The RFID tag is then moved forward into a next position and the interrogation process is repeated, starting at the minimum RF power. The process continues until the RFID tag is out of interrogation range even at a maximum RF power or some other user-defined stop point. The power level and position are stored at each position of the RFID tag during this process. The data is compiled to create a profile of the RF performance, which can then be used in a variety of ways to improve system performance.

An RFID print system includes an RFID printer and reader, a host computer that transmits a data stream containing instructions or commands to the RFID printer for encoding an RFID tag, and a data manager that receives EPC data or other data from the encoded tag. The data manager transmits the data to the host computer, which can then compare what was encoded to what was intended to be encoded. The host computer can then transmit signals to other devices in the system for appropriate action, such as when the encoded tag is defective.

摘要:
Analytical methods and devices are disclosed for separating low abundance analytes by electrophoretically driving the analytes through a sieving matrix to first remove high molecular weight species. Subsequently the remaining low abundance analytes are electrophoretically focused onto a capture membrane where the analytes become bound within a small capture site. After this step the capture membrane may be allowed to dry and then attached to a conductive MALDI sample plate.
