Magellan Offering Licensing for Anti-Collision IP
Magellan Technology, an Australian provider of RFID systems, has launched a reasonable and non-discriminatory (RAND) licensing program granting the right to use intellectual property (IP) covered in Magellan's newly granted U.S. patents (Nos. 7,259,654 and 7,248,145). Licensees that sign up before the end of 2007 will be charged a lower participation fee than those that join after this year. Equivalent patents have already been granted in Europe. The IP is used in anti-collision specifications described in the ISO 18000-3 Mode 2 and ISO 18000-6 standards, and relates to the ability of microchips to retain their state when they lose power while in an interrogating field. This ability is variously referred to as "persistence" (ISO 18000-6) and "TRAM" (ISO 18000-3 Mode 2), Magellan explains, adding that interested parties should contact the company at firstname.lastname@example.org for more information.
Dust Networks Unveils WirelessHART-based Sensor Networking Products
Dust Networks has announced a family of wireless sensor networking (WSN) systems designed for industrial environments. The SmartMesh IA-400 family of products complies with the WirelessHART standard, which focuses specifically on the needs of the process industry. The standard defines wireless 2.4 GHz communications and leverages the company's Time Synchronized Mesh Protocol (TSMP) technology. The WirelessHART standard is compatible with the more than 22 million HART-based devices installed in industrial plants worldwide, and was recently ratified by the HART Communication Foundation (HCF), an independent, not-for-profit organization. The new WSN systems include network optimization and intelligent routing algorithms to improve reliability and offer low-power operation. According to Dust Networks, the systems come with application programming interfaces to more easily integrate with industrial automation systems. In addition, they offer more than a decade of battery life, when powered by a pair of AA batteries, and incorporate 128-bit encryption. The systems include the PM2510 embedded network manager, as well as two mote form factors: the DN2510 MoC, integrated in a 12mm by 12mm system-in-package (SiP), and the M2510 RF-certified mote module. Products are expected to be available in the first quarter of 2008.
VeriChip, Digital Angel Partner With Receptors LLC to Develop Glucose Sensor
VeriChip and Digital Angel have teamed with Receptors LLC, a company in the field of proteomics (the study of proteins) and the development of artificial receptors. The partners will work together to develop an RFID-enabled sensor tag that can make it easier for diabetics to monitor their blood-sugar levels, and will develop a prototype glucose sensor to be used in conjunction with an implantable bio-sensing RFID microchip. Last year, Digital Angel—a St. Paul, Minn., maker of RFID tags for identifying and tracking animals and other assets, and a subsidiary of Applied Digital—first announced a goal to develop a glucose-sensing prototype tag by October 2007 (see Digital Angel Developing an Implantable Glucose-Sensing RFID Tag). VeriChip, Digital Angel's sister company and a fellow Applied Digital subsidiary, will manage the partnership project, with the assistance of Digital Angel. According to the companies, Receptors will be responsible for demonstrating a self-contained glucose-sensing system. VeriChip says it expects to have a functioning prototype within six to 12 months.
