"Up Beep" is a safety alarm system for the elderly, built on optical distance sensors. By calibrating the detection range appropriately, the system achieves an accuracy of up to one centimeter. Developed by a team of occupational therapists with many years of clinical experience, it provides early alerts before an elder attempts to stand, while significantly reducing the frequent false alarms common to traditional alarm systems. The device is designed for ease of use: it requires no complicated connections to systems or networks—simply plug it in and it is ready to operate. This ensures safety, accuracy, and true simplicity in application. Suitable for scenarios such as standing up from a seat, leaving a room, or rising from the toilet, it effectively lowers the risk of falls. "Up Beep" is ideal for day care centers, elderly centers, and residential care homes, serving as a precise, reliable, and user-friendly tool that offers caregivers peace of mind while safeguarding the wellbeing of older adults.
