7. Proposed Projects SMART Seat Oil Level Sensor Poolside Child Sensor
Patient Alarm System

8. SMART Seat
Existing problem arises that there is no adequate way to electronically turnoff the passenger side airbag. As of now, the primary method is done manually by the turn of a key. Problem persists that if a user forgets to turn off the passenger side airbag, a child can be severely injured or killed.
Second problem arises is where the passenger is located when the Airbag inflates. If the passenger is leaning forward, slouched down, or a child, we do not want the airbag to activate with the same amount of force. Our seat would determine where the passenger was sitting along with the passenger size and constantly update and control the needed force to safely inflate the airbag so the airbag does not do more harm than good.
Requirements
Various sensors integrated into a web of sensors to determine if a human being large enough to safely activate the passenger side airbag.
Run off car battery
Justification of Dismissal
Could be costly
Highly integrated web of sensors could get complicated

12. Oil Level Sensor
To measure level of the oil in an engine (on a lawnmower) at any given moment, considering the high temperature, different inclines.
Could be separated into different blocks.  Also might need a circuit, that would amplify that given signal if necessary. Also a circuit that would shut off the engine if there is no oil, or if oil is too low.
Requirements
Accurately measure oil no matter the weather, incline, humidity, etc.
Run off external battery

23. The poolside saver will be built to safely monitor and determine the existence of young children near a pool. The existence of a young child, near the pool without proper supervision from a nearby adult, can easily fall into and drown within seconds. Our product will determine if the child has fallen into a pool and send off an alarm inside and outside the house to alarm nearby patrons. Our product will also report the water temperature, air temperature, etc. to a remote indoor display.

34. Key Risk Areas
Developing and implementing a wave sensor could be very complicated
Not much market on workable child safety poolside devices
Prototyping would be hard. Can not carry large pool into EMS building
Outdoor design requiring waterproofing
Needs to be near foolproof, should not go off with falling branches, excessive wind, etc.

35. Patent Search 1 1: Patent # 6,727,819
A pool guard alarm provides constant security at one or more entrances to a pool area. The alarm utilizes a delay timer to provide an authorized entrant the ability to enter the pool area and reset the alarm before an audible alarm is sounded. The alarm further guards against pool entrances being left inadvertently open by sounding an audible alarm if a pool access point is not closed within a specified time period after being opened.

36. Patent Search 2 2: Patent # 6,583,724; Pool Alarm System
A pool alarm system for alerting when an object such as a child has entered a pool filled with water. The pool alarm system includes, a sensor assembly for detecting when an object has entered the water in a pool. The sensor assembly includes a housing that is mountable on a side wall of the pool. A first sensor is mounted on the housing for detecting movement of the surface of the water. A warning assembly is provided for warning an individual in a vicinity of the pool that the sensor has been activated.

37. Patent Search 3 3: Patent # 6,259,365; Laser Security Fence Apparatus
A laser security fence apparatus is disclosed for providing a warning signal in response to an intruder of a restricted area. The apparatus includes a laser generator for generating a laser beam and a first mirror aligned with the laser beam for reflecting the beam. A second mirror is aligned with the first mirror for reflecting the beam reflected by the first mirror and a collector is aligned with the second mirror for collecting the beam reflected by the second mirror. A microprocessor is associated with the collector and the generator for sensing when the beam is broken by the intruder so that the beam is not received by the collector. An alarm is connected to the microprocessor for actuation by the microprocessor when it senses that the beam is broken so that the alarm provides the warning signal.
