10. Database information is accessible manageable and processed in the user interface Hardware We did not have the mannequin for our first demo For that reason most of our time has been used to integrate our sensors into the mannequin For a detailed schematic please refer to figure 2 in the appendix We have two push buttons to verify if the student pinched the nose while providing the air to the victim Also we placed two push buttons 4 on area where student 15 supposed to verify pulse of the victim Also there is a pressure sensor in throat of the mannequin to detect if the student provided air to the victim This is detected by measuring the change of pressure caused by the air provided from the student We substituted the LED simulating the pulse of the victim with a buzzer that will make a sound when the victim has been successfully resuscitated Regarding our estimated budget based on the project status we haven t made any changes thus no extra purchases have been made Making an estimate of the future expenditures it is clear that we will come very close to matching the estimated budget at the beginning of the project For a more detailed budget analysis please make reference to the budget analysis section Introduction Our project proposal presented a challenging problem develop an electronic teaching assistant mannequin in order to help instructors and professors teach CPR techniques Some of things we

15. rection of minor bugs left over from phase 1 However due to the increasing complexity of database operations including some processes that were overlooked the focus in the beginning of this phase has been changed in order to deal with the new processes The first important task of this phase was to modularize the database connection methods into one class clsConnector cs The class is set up to have two public methods one for setting the search parameters and one for connecting to the database and returning the data retrieved The parameters sent to the class are the query to be executed and a search index which when sent through the method 1s switched to determine which internal method will be executed for the database cycle For example if I were to send SELECT FROM students 4 as the parameters the class would 12 know to use first parameter as query determine that it needs to use method 4 to get desired data For a more time based representation please refer to the appendix figure 2 The next few tasks materialized when the Create account process was created where the software developers realized that processes would also have to be created to be able to add courses sections and students Pair programming became necessary to complete these tasks as fast as possible in order to not fall behind in the training process which has been taking place in parallel with the new form creation and database manipulation C
