ShotSpotter Gunshot Detection System

Sustainability Issues

Gun-related violence has become a pressing issue in many communities and resulted in a high level of healthcare cost and productivity loss for society. While the gun violence issue has many underlying causes, mobilizing law enforcement to act effectively and efficiently after the occurrence of shooting incidents is critical in preventing further shootings from happening. However, 8 out of 10 gun violence incidents are never reported to law enforcement for many reasons. Therefore, reporting shooting incidents to police in a timely manner becomes the critical first step since they cannot respond effectively if unaware of the incident. “ShotSpotter” is designed to solve this issue and reduce gun-violence by detecting gunshots and notifying law enforcement for the location of the shooting incident.

Technology: ShotSpotter

  • Acoustic sensors (high-sensitivity microphones)  are installed in communities and buildings to detect gunshots in large and complex geographies
  • Once acoustic sensors identify and time-stamp impulsive noises (gunshot, the system then triangulates the location of the sound source to within 25 meters and runs features of the sound through machine classification
  • The Incident Review Center (IRC) human experts confirm the machine classification and publish an alert to law enforcement within 30-45 seconds
  • Notify law enforcement and first responders via a push notification, including precise location of the incident

Stakeholders 

  • Law Enforcement
  • Municipal Government
  • University Campus
  • Department of Transportation
  • Citizens

Deployment 

  • Law enforcement identify “hotspots” of gun-violence incidents and engage citizens for employing the technology
  • Local government launch a pilot program to install Shotspotters in the neighborhood
  • Monitor performance of the detection system and provide feedback to provider
  • Install Shotspotters on citywide scale, including street, university campus, and park

Sensor-Packed Pedestrian Crossing

Crossing1Crossing2

Sustainable Problem: Civic Engagement, Safety

Sensor-packed pedestrian crossing is fit for a modern city

Technology:

  • A prototype LED crossing uses sensors to respond to the movement of vehicles, cyclists and pedestrians
  • “We’ve been designing a pedestrian crossing for the 21st century,” says Usman Haque, Umbrellium‘s founding partner. “Crossings that you know were designed in the 1950s, when there was a different type of city and interaction.”
  • This smart crossing doesn’t just look more modern than the 60 years old versions; it uses machine learning to make the crossings safer. Figures from the Transport Research Laboratory show that 7,000 incidents happen on them each year in the UK.
  • The actual crossing doesn’t exist until it’s safe for you to cross – then LED patterns appear to direct people and stop cars.
  • The machines could also learn to project the crossing at a slightly different orientation if, for instance, everyone makes a beeline for a certain shop after a school days.

Stakeholders:

  • Umbrellium
  • Insurance Firm – Direct Line
  • Cities

Deployment/Implementation:

  • The project is still some way from completion.
  • To speed up the process, the code behind it is being made open source.
  • Deploy when figure logistics of implementation are figured out
  • Have multiple detection systems, to be fail safe such as version that has a pressure sensor which detects where footsteps are.

Comments to: World’s First and Largest Vacuum Air Cleaner #BT2443

The results confirm that the tower captures and removes up to 70% of the ingested PM10 and up to 50% of the ingested PM2.5. For a tower in an open field in calm weather, this provides PM10 reductions up to 45% and PM2.5 reductions up to 25% in a circle with diameter of more than 20 m around the tower. When the tower is applied in semi-enclosed or enclosed courtyards, the beneficial effects can be much larger. These statistics are astounding to me and these towers can help many people in very polluted areas.

BIOMETRIC GUN LOCK

Sustainability Issues

As the 2nd Amendment of the U.S. Constitution grants people the right to keep and bear Arms, 40% of the American households own at least one gun for protection. However, these legally obtained firearms are often used by unauthorized users to commit crimes after they are stolen and lost. Statistically, people who kill other people with guns in America acquire only 3% of their guns at gun stores while the other 97% are obtained through other means. Thus, preventing unauthorized use of firearms become critically important to protect not just our families but other innocent people from gun violence.

Technology: Biometric Gun Lock 

  • Sentinl, a Detroit-based startup is designing a biometric gun lock called Identilock. Attaching to a gun’s trigger, it unlocks only when the owner applies a fingerprint.
  • The size, weight and functionality of IDENTILOCK won’t inhibit common storage and staging methods of firearms.
  • IDENTILOCK provides quick access to working firearms in a crisis scenario when the authorized user put his or her fingertips to the biometric sensor, just like unlocking your phone.
  • IDENTILOCK prevents the use and discharge of the firearm by unintended and unauthorized users.

Stakeholders 

  • Gun owners
  • National Rifle Association (NRA)
  • Firearm manufacturers and dealers
  • Legislative bodies at federal and state level

Deployment 

  • Identify compatibility and feasibility of installing the biometric gun to majority of handguns in the U.S.
  • Launched a pilot program with local law enforcement to test the prototype
  • Gain legislative support from federal and state level for gun lock related products
  • Sell them at firearm dealers as a optional but recommended part

Car to Car Communication

Problem: Safety  

With a estimated 1.3 million deaths per year and 20-50 million injuries due to motor vehicle related incidents, the ways in which we interact with cars presents a significant sustainably risk to both drivers and pedestrians.

Technology: 

  • Car to Car communication allows for the transfer to data from a few hundred meters away
  • Information on cars position, speed, steering wheel position, brake status, and more is relayed
  • Readings from other cars are transmitted every 10 seconds

Stakeholders: 

  • -Governments
  • -Automobile Companies
  • -Pedestrians
  • -Vehicle Consumers

Deployment:

  • The first step with be developing reliable prototypes of the technology to initiate its position in the market.
  • Agreements between car companies will need to be made to create a communication system that is universal or compatible across the industry.
  • Due to the high level of cost needed to implement the systems initially, involvement from governments will be needed to drive policy change and provide subsidies to reduce overall cost.
