Lifeline

Philips Lifeline, a medical alert industry veteran, stays at the forefront of fast response technology. Consider its fall-detection system, which consists of three sensors that record acceleration and barometric pressure and utilize algorithmic prediction to determine the kind and severity of a fall.

Don't worry if this science seems like, well, science to you. Philips' products blend them into simple-to-use features that need minimal user knowledge. For example, the fall detection system instantly informs the North American-based response center, where a live agent is dispatched. Other functions, such as GPS location technology and two-way audio conversations, are also designed to function smoothly and intuitively when the user is in an emergency situation. Philips' service is as dependable as its technology. Live agents are accessible 24 hours a day, seven days a week, and respond in line with each user's specific emergency plan.
