21
Lightweight IP Internet protocol implementation on the Stellaris Sample API Format Dynamic DNS Booster Stack Lite Stellaris and MSP430 wireless protocol
22
Google App EngineTraditional Server Non-relational database structure Relational database structure Inherently a distributed architecture (Data replication is automatically handled) Must manually configure a distributed architecture No join operations are available Join operations are available Automatically creates a full application environment Must be hosted on a server for remote access
23
No need for relationships between tables No join operations will be needed for the queries of our application Simplicity of uploading new versions of the server application via an Eclipse plugin Central administrator console 10 server applications allowed for a single Google account (Allows for plenty of testing) Enough resources to allow for a fully operational application
27
Utilizes the "simple_list_item1" menu layout When a menu item is selected, the corresponding class, containing the.xml layout load and the functionalities, will run
28
Allows the user to view the current provider and enter in a new provider Current provider textview displays the company name and the residential rates To enter in a new provider, the user would have to enter the name and the rates
29
Input wattages for specific devices controlled by a particular subsystem Android Spinner objects will be used to select between different fixtures (For Dimmer and HVAC) Textfields used for wattage input
30
Textview used to display the wattages of the selected fixture Spinners will be used to select a specific fixture It will always display the TV wattage (Due to only 1 television set will be controlled)
31
Allows the user to calculate the monetary cost of the electricity usage according to a specific date or month Utilizes a DatePicker object to choose thedate Utilizes a Spinner object to choose the month
32
Tabular interface for each subsystem Status page and voice recognition reference page available through the option button Each tab remains its integrity until the user exits the control interface Each tab contains a voice recognition activation button
33
Allows the user to control the brightness level of lighting fixtures Checkboxes are used to select lighting fixtures SeekBar object used to choose the brightness level Button used to set light level
34
Allows the user to control the different functions of the HVAC subsystem Fan has the following options: ON and AUTO System has the following options: COOLING, HEATING, OFF
35
Allows the user to utilize typical universal remote control functions.
36
SpeechRecognizer Class that converts speech to text RESULTS_RECOGNITION Array of possible candidate sentences CONFIDENCE_SCORES Weighted value from -1 to 1 rating the accuracy Bag of words “Dim the kitchen lights to fifty percent” ‘lights’ + ‘fifty’ + ‘kitchen’ + ‘percent’
