P13036 Notification Alert System Objective: Functional Overview: 2012-2/2012-3 Objective: In the deaf and hard of hearing community a need exists for a small, inexpensive notification and alert device. This device notifies the user of alerts via high intensity flashing lights and through the use of a shaker. The device is controlled by the user wirelessly via Bluetooth through a handheld device such as a cell phone. Functional Overview: Android ® Device Customer Needs: Small and lightweight for travel Flashing high intensity LEDs Bed shaker adapter Rechargeable batteries LCD display to view time and notifications Low battery indication LED Bluetooth to communicate to Android® devices Receives notifications of text messages and emails. Mobile Application to set/cancel alarms and control High Intensity LED and shaker. User friendly Physical alarm turn off on physical device On/Off switch for travel Durable housing design BlueGiga ® WT12 UART GPIO Bed Shaker Raspberry Pi ® GPIO LCD Display GPIO Alert LED’s Electrical Overview: PCB Layout: On/Off 5 V 3.3 V TX/RX Alarm Off LCD Screen Raspberry Pi Screen Out 6 - 12 V 8.2- 6 V 12V DC Power Supply Charge Controller Li-Ion Battery Indication Circuit Warning LED 5V Regulator Bluetooth WT12 High Intensity LEDs Switch High Intensity LEDs Shaker Switch Shaker 12 V Mobile Application Interface: Software Overview: Thermal Analysis:   +alarmSys: AlarmSystem.py +lcd : DisplayHandler.py +btDriver: BluetoothDriver.py NAS.py +main() -_restart_() : int -alarmSys: AlarmSystem.py -display : DisplayHandler.py -Serial : Object BluetoothDriver.py -run() +__init__() -alarms[]: String +buttonGPIO : int AlarmSystem.py +addAlarm(in alarmTime : string) -remoteAlarm(in alarmTime : string) +ClearAlarms() +begin(in cols : int, in rows : int) +home() +clear() +setCursor(in col : int, in row : int) +autoscroll() -write4bits(in bits : byte, in char_mode : bool = False) +pulseEnable() +message(in text : string) LCDDriver.py -isAlarm : bool = False -isNotification : bool = False -isControl : bool = False +rows : int +col : int - secondLine : String DisplayHandler.py +alarmRecv(in message : string, in speed : int = .5) +notificationRecv(in message : string, in speed : int = .5) +deactivateAlarm() +controlRecv(in time : string) +setPulseSpeed(in pulseSpeed : int) +setSecondLine(in message : string) pySerial.py +readLine() : String +Serial() : Object Case Design: Results: Fully functional alarm clock with bed shaker and high intensity LEDs. Able to communicate with Android ® mobile devices via Bluetooth to receive emails and text messages which can be displayed on the device’s LCD screen. User friendly mobile application that controls enabling/disabling alarms, high intensity LED flashing patterns, and bed shaker shaking intensities.
