Theme parks, airports, hotels, libraries, corporations, etc., all have general ideas of how many people are on their premises throughout the day or year but they do not know the instantaneous count of people over that area.

Our solution for accurately counting individuals entering or exiting an area is a portable device which can be mounted above a door frame. It will consist of several components:

-Mixed sensor module--Passive infrared sensors for detecting a human being about to cross a doorway and trigger ultrasonic sensors
--Ultrasonic sensors for detecting the heights of individuals, whether they are entering or exiting, and determining whether multiple people are crossing the threshold simultaneously
---We will use different frequency ultrasonic sensors focused at different angles to gain topology information at different locations simultaneously
---We will trigger sensors successively to gain topology information at given locations at different times
--Possible infrared camera to better detect boundaries between humans


-Processing module
--Internal microcontroller for A/D conversion and initial signal processing
--External server for advanced signal processing


-Communications module
--Bluetooth or Zigbee to send data from microcontroller to external server


-Power module
--Converts standard outlet power to required sensor, microcontroller, communications module demands

The project is appropriate for senior design because we are dealing with power distribution, communication protocols, and signal processing.

SensorInsight currently provides a camera-based solution for watching crowds flows over a wide area. Our solution is different because we focus on precisely counting people entering or exiting an area. We seek to build a much cheaper solution than one of SensorInisght’s high definition cameras with our mixed sensor module.

Smart Patient Gown for Monitoring ECG signals

Featured Project

Mike, Raj, and Sid created a "Smart Patient Gown for Monitoring ECG/EKG Signals" to improve doctor and nurse workflow and to create a platform for further improved healthcare instrumentation interface.

This project featured:

-Wireless data transmission

-Real-time ECG/EKG Analysis and Diagnostics

-Visual feedback on a patient gown

-Low power circuitry

-Improved comfort compared to current portable ECG devices
