Alien Technology is a manufacturer of RFID technology. The company is headquartered in Morgan Hill, California, having the Alien RFID Solutions Center, in the Dayton, Ohio area, and sales offices in the United States, Europe and Asia. As of August 2010, Alien employs approximately 235 people. Alien produces Class 1 and Class 1 Gen 2 RFID inlays, tags and readers designed for use in manufacturing lines, warehouses, distribution centers, and retail stores. Due to potential applications in a wide variety of mass-produced electronic devices, the company received funding and technical support from a number of other manufacturers, such as DuPont Displays and Philips Components. The company has established relationships with Wal-Mart, the United States Department of Defense, The Gillette Company, Hewlett-Packard, IBM, Unisys, VeriSign, Dublin, Manhattan Associates, Microsoft, The Kennedy Group, Nashua Corporation, NCR Corporation, Zebra Technologies, and Paxar.

Embodiments of the present invention include systems with Readers and Tags in which a Reader queries the Tags with a parameter that includes a level of probability of reply according to which the Tags individually and randomly decide whether or not to reply. In one embodiment, the Tags can switch between two states: A and B. The query command also specifies a state (A or B) so that only the Tags in the specified state can reply. After successfully sending the Tag identification data from a Tag to the Reader, the Tag switches to the other state from the specified state. In one embodiment, the operations about the two states are symmetric. In one embodiment, the Tags can remember the parameters used in a query so that a short form of query command can be used to repeat the query with the same query parameters.

Methods and apparatuses for selecting a subset of RFID tags are provided in some embodiments. These methods and apparatuses utilize the susceptibility to light by persistent nodes found in passive tags. Light can be used to intentionally reduce persistence times in a particular subset tags or even an individual tag. Then, persistent nodes can be used as a selection criterion to distinguish previously illuminated tags from non-illuminated tags. In other embodiments, a power circuit receives a RF input source and generates a direct current (DC) output voltage. The circuit includes a bias circuit to supply a gate to source bias, which is independent of the DC output voltage. The circuit further includes a voltage multiplier circuit that is coupled to the bias circuit. The voltage multiplier circuit has MOS transistors with one transistor to receive the gate to source bias.

A Radio Frequency Identification (RFID) tag. The RFID tag comprises a flexible substrate and an integrated circuit embedded within the flexible substrate. The top surface of the integrated circuit is coplanar with the flexible substrate. At least one conductive element is formed on the flexible substrate. The conductive element is electrically connected to the integrated circuit. The conductive element serves as an antenna for the RFID tag.

An apparatus and method for simultaneous programming of data to individually addressed Tags. Tags contain a being addressed indicator that allows for processing of simultaneous programming commands. Specified Tags are individually pre-addressed to receive simultaneous programming Tag data is programmed simultaneously for all Tags in a specified group of Tags. Data is individually verified for each specified Tag in the group of Tags and verification includes tracking a command counter for each specified Tag.
