GANTT CHART
4
EVENTS/TASK

• ALL MEMBERS
• Toured the Fire Rescue Operation site
• Took measurements of the hoist
• More research on the proximity sensor devices
• Designing the case/dimensions
• Prepared budget ordering devices
• Testing Ultrasonic Device

5
THEORY BEHIND USING CAR ALARM SENSOR

• Microwave sensor in car detects disturbance
  entering field (moving objects)
• In case of helicopter rescues, radar moves and
  ground stationary
• Relativity gt ground can move (entering
  disturbance) rescuer stationary

6
POTENTIAL DEVICES

• MA-01 One-Zone Microwave Car Sensor
• Microwave movement detector
• One zone
• LED test indicator

7
POTENTIAL DEVICES (CONT.)

• AsianWolf MS-2 Microwave Car Sensor (12 V)
• Microwave Movement Detector
• Dual Zone
• Green Led goes on for warning zone
• Red Led goes on for danger zone

8
Design Process

• Dual zone microwave car alarm sensor available w/
  adjustable perimeters
• Outer perimeter 15ft
• Inner perimeter 10ft
• Rescuers body and harness fully contained within
  danger zone (not crossing inner perimeter)

9
Design Process (Cont)

• Utilize the warning trigger output in alarm
• Equivalent to terrain crossing into warning
  region
• Use green LED output for basis of our LED system
• Concerns exist with presence of rescuer inside
  danger region
• If its a problem, dont utilize red LED into our
  design
• Otherwise can use danger trigger output to cause
  faster blinking for distance sensor design

10
TASKS NEXT WEEK

• ALL MEMBERS
• Order microwave car alarm sensors and test
  functionality
• Research
• WALTER
• Look into what kind of LEDs needed for display
  unit
• Design LED system to be visible from 200 ft
  down
• RICARDO
• Study output characteristics of our microwave
  car alarms warning
• BAO
• Research work on design of casing
