Link to Life is an emergency alert system with monitoring service designed for use by seniors or individuals with spinal cord injury or severe physical disabilities. The service collects information on the user's medical history, medications, and allergies, together with a list of people to be called in case of an emergency. Users receive a lightweight, waterproof Help button that can be worn as a pendant or on a wristband, along with a base unit that connects to the user's telephone line. Pressing the button sends a signal to the base unit, which in turn sends a signal to a Response Center, where trained operators provide monitoring and assistance 24 hours a day, seven days a week. An operator calls the user's home phone number. The user either answers the phone or presses the Help button again to speak with the operator through the base unit, which allows for hands-free, two-way communication. If the user does not answer or answers and reports an emergency, the operator contacts the appropriate medical personnel and communicates the information included in the user's medical profile. Next, the operator calls everyone on the list of people to be notified, which may include doctors, family members, or friends. After an emergency, the Response Center follows up to check on the user's status. If the user is hospitalized, the Center can notify someone to stop the mail or feed the user's pets, and staff will place a "welcome home" call upon the user's return home. OPTIONS: Pillow switch, sip and puff switch, or wobble switch in place of the standard Help button; personal reminder service, with up to three reminder calls daily; smoke detection monitoring; inactivity monitoring, using either motion sensors that initiate a call to the Response Center if no activity is detected for a predetermined length of time, or Daily Touch-in by pressing a button on the base unit each day.
