Abstract. The Wrist Alert is intended for the use by the hearing impaired in their home environment. It alerts the user to signals such as smoke detectors and doorbells. These signals are connected to a centralized controller box, processed, and transmitted via a Radio Frequency link to the wireless wristband device. The alerting mechanism employs vibration, a discreet form of notification that helps minimize disruption to everyday life in the household. The Wrist Alert utilizes different vibration patterns to differentiate between designated priority levels and the associated signal sources.

Keywords: hearing impaired, ALD (Assistive Listening Device), RF (Radio Frequency), transmitter, receiver, vibrator
