Remember the “Help I’ve fallen and I can’t get up!” TV commercials from the 80′s? The advertised product was a personal emergency response system (PERS) for seniors that included a base station and a pendant that interfaced with an analog phone to dial out for help when the pendant’s button was pressed. MobileHelp is a more modern version of that device. It incorporates GSM and GPS features so the person using the product isn’t restricted to their home. The system’s GPS technology also allows families to locate loved ones in real-time via the Web. The system will run you $34.95-$39.95 per month.
