Status Report #5Automatic Child Safety Gate:Corry WinslowRoger BattlesPhilip So

Description: A telescoping gate with sensor technology through the interface of weight and IR sensors through a microcontroller

Overall Need

•Current Design: Many design flaws compromise safety

Overall user friendliness No anti-climbing mechanism

•3 Primary Milestones1.Sensor Testing: Weight & IR

08/24/20082.Gate Construction: Cutting 09/24/20083.Microcontroller interfacing 11/01/2008 with sensors and gate hardware

Completed Tasks•Invention Disclosure

•Web Site

•Motor specs.

•Chose load cell strip

•Slide Rails

Projected Specifications

•IR Sensors: 2 ft. sensitivity

•Load Cell: 10 lb. sensitivity

•Safety Door Sensors: Low: Closes door High: Keeps door

open Will be high as long as it senses object in

door way
