Team: Seniors for Seniors

Members: Steven Sengberg & Christopher Wilson

Project Abstract

The end goal of this project is to assist elderly people in remembering to take their medication.

The unit consists of several containers, or drums, that contain one type of pill or a specified dosage of a

pill. Several large buttons control a graphical LCD screen that allows the user to specify a time and a

day for an alarm. Once the alarm time is set the user then clicks the buttons located in front of the

containers to indicate which pills will drop at that alarm. In addition, the system contains several other

features to increase ease of use, safety, security, and user satisfaction. The device can play sound

notifications for certain selected menu options. The system includes an RFID so that only specific

people can open the machine to load pills. Similarly, the RFID reader will also ensure that the correct

person takes the pills. The unit also includes several sensors to confirm that the pills have been removed.

The system includes functionality for text messaging the proper contact when an alarm is missed.

Finally, the machine can also act as a music player with programmable SD card and attractive volume

reacting lights.

Introduction

Application Domain and Problem Description

In the modern world there are millions of Americans that take several medications daily. A 2004

Survey indicated that more than 40% of Americans take at least one prescription drug and 17% take

three or more(1). Another set of data shows that 80% of people over the age of 75 take at least one

medication and that 36% of this age group will take up to four medications daily (2). The most

significant problem preventing the treating of illness is simply remembering to take the medication. In

order for a prescription and over-the-counter drugs to be effective they must be taken in compliance with

the timing and dosage specified. It is not uncommon for elderly people to have difficulty remembering

which medicine is for which particular ailment or even to take any medication due to memory problems

and depression which contribute to forgetfulness. A person is most likely to forget their medication on

days when their schedule is hectic. There are serious consequences for forgetting to take medications.

Some problems include a delayed recovery or even more severe symptoms. More than 80% of

hospitalizations for adverse drug reactions in the elderly population are dose related (3).

Invention Proposal and Project Description

The problem presented is difficult, however, Seniors for Seniors (SFS) has presented a

comprehensive solution to medicine scheduling, the Medication Alarm Intuitive Dispenser (MAID).

MAID is a pill dispenser with several features. It is designed to be one of the most reliable and cost

effective means of adhering to strict pill timing intervals.

Current Market Solutions

There are several other products that attempt to perform a similar function to MAID.

Figure 1 : Other Market Solutions

Evaluations:

1. This product limits the user to a mere 4 alarms a day. It is very expensive, has a small screen and

difficult to use alarm system. In addition, the user must lift the device and shake to dispense.

2. This product is incredibly expensive and only allows 4 alarms a day. This product also has a small

screen and complicated setup.

3. This product is also very expensive. The product requires small plastic cups and lids. Replacement

items and accessories are all expensive.

Project Features

Simple, Easy-to-Use and Set Up

MAID is conveniently equipped with an easy setup; a standard simple wall outlet will suffice

for power. There is no need to tinker and fiddle with difficult to insert batteries. The unit also features a

user friendly interface with reactive, light up large buttons for easy use. Furnished with a large

graphical LCD screen it is simple to read text and interact. The GLCD also includes a bright backlight

that is automatically turned on making it easy to read at any time of the day.

Variety and Flexibility

MAID is able to hold up to 7 different types of medications. Utilizing a simple interface an

individual can set up to 12 timed alarms for different days at different times and specify which pills to

dispense at that time.

Secure and Accurate

MAID is secure and accurate. An easy- to- use RFID card reader ensures that the qualified

individual will be the only one granted access to load pills into the pill compartments. In addition, the

card reader will also confirm the proper individual is there to receive the correct pills in the case that

there is more than one machine.

Informative and Customizable

The main priority of the product is to alert an individual to take their pills. The system comes

with an alarm and several preset songs to use as the warning, allowing users to customize their medical

schedule experience. As a further level of customizability users can add their own songs by placing it on

an SD card. MAID also includes a temperature sensor to inform the user of the current temperature

conditions in Fahrenheit or Celsius. This product is incredibly informative and it will even announce

the different options as the user browses the menus.

Reliable and Safe

Intelligently included in the design is a sensor to confirm that the pills were dropped from the

pill dispensing area and there are warning messages if a pill fails to drop. In addition, a GSM module

has been added to the project that allows it to text message a designated person if any of the alarms goes

off and no one retrieved the pills. The user can easily set this contact phone number from the menu. On

the event of a power outage the device retains the time, date and all alarm settings.

Entertaining and Fun

MAID can also entertain for hours with a complete light up display that responds to the volume

of music being played. The device presents this viewing experience in conjunction with clear stereo

sound. Also included for even more customizability in the project are two separate adjustable left and

right audio controls that allow the user to manipulate the sound to their own preferences. In addition, the

front pill selection buttons can be converted to play musical notes. The last incredible feature allows

users to see and play different videos for their amusement.


Technical Objectives and Description of Operation

The main object of the MAID is to ensure accurate and safe distribution of pills to users. This

section details the expected Operation and Goals of MAID. A Primary objective of our project is to

design a system that can sound an alarm at a certain time and dispense the proper medication with RFID

confirmation.

The device dispenses the proper amount by relying feedback through an optical encoder and

precision control with stepper motors.

The RFID reader will have to read a card and confirm that it is the correct person trying to receive

the medication then send a signal to allow the medication to be dispensed.

The microcontroller is connected to a real-time clock and also sends the appropriate signals to the

CPLD and peripherals.

The CPLD contains the state machine that controls the motor motion.

Main Menu Operation:

1. Upon turning on the device the user will see the logo and animation for M.A.I.D. on the

Graphical LCD.

2. The User will then see the main menu. The Main menu has several different selection options in

addition to displaying the day, date, month, time, and temperature at the top of the screen.

3. The Main menu will always display the current time in addition to a) Adjust Alarm b)Load

Medication c) Select Sound d) set time e)gsm debug f)change temp unit g) change phone # h) set

quick alarm i)play music j)play video k)play game l)set voice on off

4. The User can access the loading medication and setting time menus if they are the administrator.

5. If the User tries to swipe with the Patient Card nothing happens at the Main Menu

Set Alarm Selection

1. Once adjust alarm is selected the screen will then prompt the user for if they wish to set an alarm,

remove and alarm or return to the main menu

2. If Set alarm is chosen screen will then display All the Days of the Week and a cursor indicates

which day is currently selected and it will also display "Back" which allows the user to Return to

Previous Screen

3. Once a Day is selected the screen will then display The Day at the Top and 6 slots for different

alarms as well as "Back" to Return to the Previous Screen. There is also a "Next Page" option

that allows the user to see the other 6 alarms that can be set for that day.

4. After setting the time the user is prompted to select which pills should be dispensed at that time

by clicking on the 7 drum buttons.

5. Once one of the alarms is selected the user will then use the arrow keys to select the proper time

for their alarm, and the previous screen will be updated to show that there is an alarm set.


Remove Alarm Selection

1. Once adjust alarm is selected the screen will then prompt the user for if they wish to set an alarm,

remove and alarm or return to the main menu

2. If remove alarm is chosen screen will then display All the Days of the Week and a cursor

Return to Previous Screen

3. Once a Day is selected the screen will then display The Day at the Top and 6 slots for different

alarms as well as "Back" to Return to the Previous Screen. There is also a "Next Page" option

that allows the user to see the other 6 alarms that can be set for that day.

4. The user can then select any of the 12 alarms and just click on it to remove the alarm.

Load Medication Selection

1. When Set Alarm is selected the Screen will display "Swipe the Administrator Card to Proceed" It

will also have a "Go back" option if the user selected the option accidently.

2. MAID will then wait until it detects that the Administrator card was swiped.

3. When the administrator card is swiped the words "The Pill Area is now Unlocked" appears. The

servo unlocks the pill section. If the pill section is not opened within 8 seconds the servo relocks

and sends the user back to the main menu.

4. After a few seconds will then display "Select a Pill Type to Load" it will also display all the pill

types and a back selection.

5. The user can then use the arrow keys to select the type of pill. Each time the user clicks the

wheel will rotate one slot.

6. When the user is finished back can be selected or the user is automatically returned to the main

menu when the door is closed. Once the door is closed the servo automatically locks it.

Sound Selection

1. This screen can be accessed by anyone. It allows the user to choose which song to play as an

alarm.

2. The screen will display the "Change Alarm Music." Also displayed are the current song number

and the file name. The user can use the arrow keys to change the song and then click play to hear

the alarm.

Set Time Selection

1. When this option is selected the user will then be prompted for the administrator card. If the

wrong card is swiped the screen will display which card is being swiped.

the GSM.

2. The Options for this menu are 1) start GSM 2) send SMS 3) Listen GSM and 4)Send AT

3. When initializing the GSM this screen can be used to see if it has been registered to the network.

4. Send SMS allows the user to send a message and the temperature to the contact phone number

3. There are also "back" and "accept" buttons, if back is selected the user returns to the menu, if

accept is selected the selection is saved as the alarm.

Change Temperature Unit Selection

1. Clicking this option will immediately change the temperature on the Main Menu to the other

unit. Only does Fahrenheit and Celsius.

Change Phone Number

1. This Option takes the user to a screen that displays the currently set phone number at the top.

2. The user can use the directional arrow keys to change the number and can select back or accept.

3. The number is saved to EEPROM and like the alarms is not lost in a power out.

Set Quick Alarm

1. This setting is mainly for demonstration and testing purposes. It will automatically set an alarm

for 5 seconds after the current time.

2. The alarm is also set so that each of the medication types should be dispensed.

Play Music Selection

1. This screen is similar to select sound but it has several options including "play all" "pause" "fast

forward" "reverse" and back.

browses through the main menu the voice will announce each selection as well as saying

"selected" when a particular option is chosen.


Medication Alarm and Pill Dispensing

1. When the Time for an alarm is activated the screen will switch to an alarm menu where it

prompts the user for the patient card.

2. As the alarm menu is displayed the selected alarm music will also begin playing.

3. If no one comes to retrieve the pills, after a certain time the alarm will send a text message to the

designated number and switch to a screen to notify the user an alarm was missed.

4. If the patient is there and then swipes their card and the following will occur:

a. The motors for the specific pill type will rotate and drop the pills into a bottom container.

b. The IR sensor will detect that every pill that was selected dropped.

c. If a specific pill type does not drop there will be a warning prompt after the rest of the

pills have been dispensed.

5. The user will then be taken back to the main menu.

Concept Development and Planning

The mechanical design and the project description have changed several times after the initial

presentation of the design. Below are some of the design decisions and models planned before the

current version.

1. The first version although independently developed resembled several of the current market

solutions. It used several of the medicine boxes similar to the MTWTFSS boxes offered in

pharmacies. The main dropping mechanisms at this point were several solenoids at each of the

box locations.

a. Main processor was to be a larger sized MSP430 - Problem with this was the amount of

shipping time and so this was eventually changed.

b. Main methods of dropping pills were solenoids. At the time of research, however, there

were none on the market that met the power and cost constraints of the project

c. There was no second pair of IR detection to determine if pills were dropped

d. RFID was not present in this design or the RTC.

e. The pill boxes were utilized instead of the Rotating wheel

2. The second major version was developed after conversations with Dr. Schwartz and in class

suggestions to the project.

a. This design had the main microprocessor as the Atmega, and then it would communicate

with several smaller MSP430s

b. The Main method of dropping pills was changed to motors to better support the new

circular dispenser design

c. Second pair of IR detection added along with another button to drop pills

d. RFID was added to this design for complexity. It would also function as the component

to control who would load the pills and set the alarms

e. Rotating wheel design now implemented

3. The version for the initial class presentation

a. This design has the main microprocessor as the Atmega specifically for a greater number

of I/O pins

b. This design added an additional Atmega to control EEPROMS for sound selection

c. The MSP430s were replaced with a CPLD for a greater pin count

d. Graphical LCD added instead of smaller LCD to show more on the menus

e. RTC added to keep track of day.


4. Completed Prototype Version (Demonstration Day)

a. This design has the main microprocessor as the Xmega128A1 as the sole microprocessor.

This particular chip had a breakout board available that was easy to use for testing as well

as 78 I/O pins.

b. SD Card was added for sound selection instead of the EEPROMs. The Internal EEPROM

would be used to keep track of Alarms and other user customized selections.

c. CPLD implementation was changed to allow all the motors to run off of it.

d. GLCD as well as the backlight to it was added.

e. DS1307 and battery were used to maintain time instead of internal RTC.

f. RFID and GSM added for features.

g. Servo added for a locking mechanism.

h. Stepper Motors replaced the original motor purchase. These were connected to the

dispensing drums with rubber bands.

i. Temperature Sensor added

j. Housings and enclosures for all components built out of wood.

k. Also included custom switches and potentiometers with dials

Final Prototype as seen on Demonstration Day:

Components and Technology Selection

Digital Components

1. Atmel AVR Microprocessor (Atmega 128A1) - The Atmega128A1 was chosen over the original

Atmega324P, PIC and the MSP430 of junior design, mainly due to its number of Input / Output

pins (78 available). In addition, a breakout board was purchased from sparkfun to allow easy and

immediate debug and testing. The chip also has a much larger memory which was needed for the

incredible amount of code utilized. The chip can support up to 4 SPI, TWI, and UART devices.

It is low power and faster than the other. See device manual for other details.

Figure 3: Xmega128A1

2. CPLD (MAX7000s-EPM7064SLC44-10) - The CPLD is necessary once again due to the large

number of Input / Output pins. This particular unit has 40 pins that can be used. In addition, the

functions of the Pins and the controls can be easily reconfigured for any purpose.

3. RFID Reader - This component is necessary because the MAID needs a secure means of

determining identification. It is critical to have someone who is knowledgeable about the

medications and dosage to be the only one able to load and set alarms.

4. Real Time Clock (RTC - DS1307) - This component is significant for several reasons. The first

is it needs to be powered with an additional 3.3v battery. This allows the unit to keep track of the

date and the time even if the power is removed. The RTC is also easily communicates with the

microprocessor through I2C communication.

5. Graphical LCD Screen (TG12864H3-04A) - The graphical LCD was chosen over the standard

LCD because the Graphical LCD has more room on the screen to display information. This is

critical because the user interface needs to be simple and easy to set up, a larger menu is one

method of accomplishing this goal. In addition the Graphical LCD also allows pictures which

will be used for a logo and instructions. The Graphical LCD can also be used for video.


Figure 4: GLCD

6. Internal Chip EEPROM - It should be noted that the internal EEPROM is only 2k but it is large

enough to store the alarms and several user customized choices.

7. SD Card - The SD Card is necessary because the sounds that are used take a substantial amount

of space. The Atmega processor does not retain enough internal memory to save the sound

therefore external memory is needed. In addition, this memory must be non-volatile so the sound

files are not lost. Finally, the SD card is convenient to use because most computers have a port

that will support the card.

Figure 5: SD Card

8. Temperature Sensor - This component is used to allow the user to see the current ambient room

temperature. This is different from the built in chip temperature sensor which only detects the

chip temperature.

9. GSM Module - This component was necessary to send text messages to the designated number

as warnings if pills were not taken. The module used has an easy to use housing to slip the SIM

card in.


Analog Components

1. ADC Components

a. Infrared Sensors / Photodiodes Sensors - The Infrared and Photodiodes are used together

for detection. The first pair is necessary to detect if pills are actually dropped when the

alarm goes off. The main concern is the machine has no simple means of detecting how

many pills are left in the dispenser. The other pairs are used in conjunction with the

motor encoders for position.

b. Volume Control Potentiometers - This component is mainly so that the user can adjust

the volume level of the alarms. Turning the control all the way in one direction will turn

off the sound, the added flashing lights are critical as an alarm indicator.

c. ADC Pins are built into the Atmega and this allows us to read in Analog Values

specifically for the photodiode receivers.

2. DAC Components

a. Speakers - The speakers are needed to play sound for the alarm.

b. Amplifiers (LM386N) - The op amps are necessary to boost the sound to increase the

volume of the alarm.

c. DAC (LTC1661) - This is a serial DAC to allow us to save us on use of pins.

Mechanical Components

1. Stepper motors - The motors are the key component in driving the Pill Dropping mechanism.

The pill dropping system work so that the pills are loaded into a large wheel. This wheel is then

turned by the motor to dispense the pills. The wheels/drums that are turned by the stepper motors

have encoding placed on them for position.

2. Servo - The servo is an easy component to use to control the locking mechanism for the pill

dispensing area. It can have several set positions that are easy to program for a simple lock

unlock state.

Miscellaneous Components

1. LEDs - LED's are necessary in several locations in the design. The most important is the LEDs

light up when the pill selection button is pressed. This lets the user know which pills are selected

to drop at a specific alarm.

2. Push Buttons - The Push Buttons are used for two primary reasons. The first reason is that

several push buttons are used to control the menu options on the LCD screen. The second reason

is they are used to select which pills are to drop at a specific alarm.

3. Resistors

4. Capacitors

5. Voltage Regulator (LM3940IT) - Several Components require a 3.3v power supply instead of the

5v supply provided by the wall plug.

Figure 6: LM3940IT Voltage Regulator

6. Hardstock Wood - This material is cheap and study. It will be the primary construction material

for the casing of the MAID.

7. Screws, Brackets

8. 3.3V Battery - Necessary for the RTC.

Software Flowcharts

There was a substantial amount of programming that was involved in this project. The following

diagrams are only a very general description of the process that occurs, and it does not even cover all the

options and situations that are involved in the actual project. A significant time constraint prevents us

from discussing all the possible options. In addition, these are not detailed flowcharts that discuss the

variables manipulated; most of the boxes represent entire function calls.
