The rapid development of the Internet of Things (IOT) along with devices that can connect to the outside world to produce markets that previously never existed.

One such thriving market is wireless health monitoring systems. To take full advantage of a wirelessly connected healthcare environment, Aether Engineering is leveraging Wind River Systems' established cloud platform to provide interactive diagnostic tools for home use. The Aether team is designing a suite of products specifically created for home use that deliver seamless communication with the physician.

Software Design
Design Team
The Smartest and Brightest

Hardware and Software teams collaborated with constructive design ideas to make Sound Scope possible. The hardware team efficiently designed and built the hand held device. The Software team, took that device and expanded its usability through use of IOT(Internet of Things) to bring ease of use. Both teams of engineers come from different backgrounds and different expertise. Keep exploring to meet the engineers more in detail.

Being a non-degreed engineer in various positions since 2001, I believe I had all I needed to succeed. The opportunity the G.I. Bill afforded me to obtain my degree was too hard to pass up and I am extremely grateful for the chance to fill the Project Manager role in the development of fellow veterans and future engineers. Currently working for Northrop Grumman as a Microwave Design Engineer and finishing my degree has been quite a long and rewarding challenge, preparing me for the next phase of my reinvigorated outlook towards continued learning and leading in the engineering field.

Zak is the lead engineer of the stethoscope's sensors and audio capture system. The sound detection will utilize piezoelectric sensors as well as polyurethane components to interface with the patient's body and reliably capture body sounds. As a senior electrical engineering student, Zak brings over ten years of hands-on technical experience to the team. Zak has been working as an intern with Northrop Grumman in their Triton program for the last 18 months, and following graduation he will continue in the position of Engineer I.

I am an Electrical Engineering student at San Diego State University. I am also interning at Northrop Grumman and will be switching to full time employment at the conclusion of my final semester. Prior to starting a career as an engineer I spent five years in the Marine Corps on active duty and I continue serve as a member of the Marine Corps Reserve Shooting Team. Outside of work and school I enjoy spending time outdoors whether that is camping and hiking or a day on the water sailing. I recently became a father and am having fun learning to adapt to that job title as well.

Lionel Fox is a senior Electrical Engineering student responsible for Bluetooth integration on Aether Engineering's software team. As this role spans the gap between the hardware and software platforms, it allows him to further develop his problem solving skills by facing an array of challenges in varied areas. These include Bluetooth radios and protocol stacks, integration with embedded micro-controllers and analog circuitry, and Android application development. Outside of the academic environment, Lionel is currently a Mobile Wireless RFIC Design intern at Peregrine Semiconductor, assisting in the development and testing of CMOS RF switches and low noise amplifiers.

Andrew Handrop

Andrew is in charge of project management for the software team as well as android application development for the project. Upon graduation in the spring of 2016, he wishes to start working immediately. During the weekends he works part time at a local shooting range as an instructor and range safety officer.
Patrick is studying computer engineering at SDSU. He is part of the software team and is tasked with the cellphone's Axeda cloud integration. The Android application will have the ability to send information to the cloud in real time and will then be hosted on a website for display purposes. With graduation on the horizon, Patrick is currently a student intern at SPAWAR for the past 4 months, with plans to either continue with them through the NP program or join the military as a CTN. His favorite part of being an engineer is that it allows him to tinker with ideas, concepts and design.

Patrick Baun

Luis is a senior computer engineer graduating this semester. He is responsible for designing and implementing the bluetooth connection that allows the transfer of sound files and allowing serial communication using SCO, and SPP Profiles. He also provided assistance with managing transmission of sound files sent to the cloud. Some of his other tasks involve android GUI development and website design. Prior to school, Luis served six years in the Navy as a medical lab/bio tech. After graduation he will be relocating to Miami, where he can expand his engineering career.

Helix will securely store patient information, along with any heartbeat recording the user saves.
This in turn, provides records at an instance to medical providers for review and action.

How does it get to the medical provider?
A specialized website was designed to pull data from the cloud that allows doctors to view current records and compare with any historic files.
Data in the website is always current and updates via a background process.
Android APP Sound Scope

Designed to fully integrate with device stethoscope
Cleanly routes digital sound for live streaming of heartbeat sound
Records the adequate amount of sound and allows the user to playback and review
Sound Scope is always connected to the Helix Cloud, letting users save recording where ever, when ever  
It also routes user information to the medical provider allowing feedback and communication.
Patient contact information is routed securely to the cloud and updated in the website for only the privacy of the doctor.

Why this technology?
    With increasing medical costs industry wide, and patients experiencing longer wait times, the next generation of medical devices is being created to address these issues.

Wireless health monitoring makes it possible for many health related tasks to accomplished from the patients's home. This will reduce the number of doctor visits and lead to fewer overall appointments. The costs associated with these medical appointments will be reduced, as many can easily be addressed without the patient ever entering the clinic or hospital.
Hardware Design Features
The Solution

The first design in Aether's suite of devices will be an electronic stethoscope capable of recording heart sounds and transmitting the audio to a cell phone via Bluetooth. The patient will then be able to playback the sound at the touch of a button, as well as making the heartbeat available for convenient physician review - from anywhere and at any time.

Ease of Use

The stethoscope will be ergonomically designed to be easily handled by the patient without unnecessarily complexities. This simplicity in functionality is owed to the design of an accelerometer, LED bank, inductive charging system and a seamless application control.

Technical Highlights

To simplify the system for the patient, the device automatically turns on as soon as it is picked up. This is accomplished by incorporating an accelerometer which detects movement of the device handset. A bank of LEDs provides illuminated feedback to the user alerting them of battery charging status, device pairing mode, and active recording in progress. The final hardware consideration pertaining to ease-of-use is the design of a wireless inductive charging system, allowing the stethoscope to simply be placed into the cradle recharging.
