Vyzin, maker of the VESAG mobile personal emergency response system (MPERS), has received three key certifications for its product, including the important CE Mark necessary to access European markets.

In addition to the CE Mark, Somerset, N.J.-based Vyzin also announced that the VESAG "mHealth watch" – which can be worn on the wrist or as a pendant – achieved Restriction of Hazardous Substances (RoHS) certification and passed the Specific Absorption Rate (SAR) test for cellular devices.

RoHS certification means that the product meets European standards for manufacturing electronics with minimal levels of lead, cadmium, mercury and other toxic chemicals. The SAR test is an American regulation that measures radio-frequency energy absorbed by the human body when using a mobile phone or other cellular-enabled gadget.

The VESAG watch/pendant module actually serves as a hub for wireless medical devices, including heart-rate monitors, weight scales, blood-pressure monitors, pulse oximeters and electrocardiograms, which send data following the ZigBee 802.14.4 standard. The mobile hub, which has a built-in GPS to track the wearer's location, uses a GPRS cellular connection to upload data to Vyzin's call center, from which healthcare professionals or an interactive voice response system helps monitor patients.

The device itself provides medication reminders and has a panic button to summon help in case of emergency.

VESAG has been tested extensively on U.S. and European networks, according to the company, including on Vodafone in the U.K., KPN in the Netherlands, VIP in Croatia, Telefónica in Spain, Orange in France, Swisscom in Switzerland and Telenor in Norway. Though the CE Mark is new, the device has been available in France since April. It also is distributed in all four of the "BRIC" countries, Brazil, Russia, India and China.

In the U.S., VESAG services are available on the AT&T and T-Mobile networks, the company says.
