This are some notes from the third day of the 2014 IEEE Rising Stars Conference.

Notes

Dolby

24 Frames per second
- Standard - slowest that could be called “motion”
TV Max
- 120 Nits Max
- Current TV’s 300-900 Nits
Viewer Visual Preferences Test Setup
- Focused projector into 27 inch LCD screen
- Maximum luminance (projector limit) - 20,000 nits
- Minimum luminance (0.1 nits)
- Diffused white (300 nits)
- Viewer preference results:
  - Black level (0.005 nits)
  - Diffuse white (4k nits)
  - Highlights (20k nits)
- The current max of 100 nits is not enough!
Today’s standards
- Brightness (100 - 500 nits)
- Contrast (1000:1)
- Viewers want 200x brightness
- Viewers want 4000x more contrast
Today’s big squeeze
- More tools to change the industry standard
Upcoming year
- High dynamic range
- Lots of tools coming out
The future is here
- Industry is going through a disruptive change
- Not only in distribution, but also in cinema
- SMPTE (Society of Motion Pictures and Television Engineers)
- Perceptual Quantizer (model based on how the human eye sees)
- High Dynamic Range Mastering Display
- Dynamic Metadata for Color Transforms of HDR and Wide Color Gamut Images (in process)
Take Aways
- Whole bunch of cool things that are coming out from the sound industry
- Entertainment technology is in a revolution that will redefine a great consumer experience
- Next generation entertainment will be a mix of more, faster, and better pixels
- It’s a great time to be a engineer in entertainment technology
- SMPTE.org
Questions
- How will the next generation of technologies affect power consumption?
  - Current screens are very inefficient
  - Technology will help to reduce power consumption
  - Quantum dot technology
- How do the new technologies affect motion?
  - New HDR technologies affect motion
  - More dynamic range means motion defects are more visible.
  - Needs to be a re-think of the 24fps standard for movies

Confronting Global Energy Challenges

Title: Confronting Global Energy Challenges Nathan Johnson Assistant Professor, The Polytechnic School Arizona State University

Power
- CO2 - Drive Down
- Cost - Drive Down
- Reliability - Drive Up
There are many pieces to the solution
- Energy systems are dynamic
- Energy Systems Modeling and Optimization
What the ASU do?
- Design Tools
  - Energy Systems Design Environment (EDSE)
- Distributed Renewables Integration
  - Duck Curve
- Power goes up when people go home at night
- Power goes down when people leave during the day
- This power profile should show itself in the next 20 years or so
- Monitoring and controlling distributed systems
  - What is happening to solar energy as things happen?
  - Dust storms, cloud, etc.
- Forecasting for adaptive energy management
- Load <-> Stored Energy <-> PC Power
- Building Energy Systems
  - Smart controls of campus electrical and cooling systems
  - Cost of electricity is more during the day than at night
  - Have 25 mW of solar installed
- Developing capability for household energy management
  - How can we make the technologies usiable for households
  - Embedded controls
  - ASU Solar Decathalon
- Using reduced metal oxides in concentrating solar power
  - Fine grains of metal
  - Thermochemical process
  - Remove oxygen during the day
  - Oxygenate at night to generate high temperatures
- Hydrogen production for biofuels
- A pathway to rural electrification
  - Battery charging stations
- Modeling battery cycling and degredation
- Solar Brayton cycle micro-grid platforms
- Measuring the effects of energy on air quality
  - Use off grid sensors
  - Monitor particulates in the air
  - Move to map this as an overlay on google maps
- Alternative energy education

The internet of things

“The next S-Curve”
Elements of the internet of things
- The industry is hyping the Internet of Things
- What is the application?
- How does it connect to the world?
- What is the intelligence controlling the world?
- Can we trust it?
Example: health/fitness devices
Example: fashion
15.03 million households connected
How will these applications connect
- Wide area connections through phone
- Combination of Bluetooth Low Energy and Wi-Fi direct will replace USB
Where is the intelligence
- Microcontroller revolution: moving intelligence from system to our hands
- Direct intelligence
- Cloud intelligence as well
- Big question: do you trust that intelligence
Wellness: compelling application
- Wearable devices that measuring things like a person’s skin trans-conduction can estimate a person’s emotional state
- Example benefits:
  - Calm people eat better
  - Calm people make better decisions
Recommendations
- Unless you have the ability to standardize everything, use something with wide existing connectivity
- Bluetooth smart (low power)
- Wi-Fi direct (high data rate devices)

Notes afterwards

Exciting areas
- Response from Dolby Guy
  - Silicon valley, entertainment; netflix sucks up a lot of bandwidth
  - Internet is reshaping our lives
  - Companies in that space: Google, Amazon, Apple
- Nate
  - Anything is storage
  - Storage can be translated towards any energy
  - Companies in that space:
What helped you in your career
- Internet of things
  - Network, you’ll cross paths with a lot of people
  - Pay attention to marketing and support it
  - Too many choices
- Dolby
  - Networking is important
  - Never knew what you will end up liking
  - People that you run into
  - The people that you run into give you opportunity
  - The people you see on the way up, you also see on the way down
  - Integrity
- Nate
  - Grad school
  - Helps you get exposed to a lot
  - Same thing as a post-doc
  - Get experience in a couple of different areas
What would you change differently in your career?
- Dolby
  - Went to school in boston, should have went to stanford
  - Life is what you make it, but there are better places you can live
- IoT
  - Sometimes got into trouble because of organizational chaos
  - Management group changed
  - Sometimes it’s time to get out of a bad situation; hard to know it
  - Been laid off 3 times in career
  - Most of the time lead to something that much better
- Nate
  - If you love what you do
  - Persue opportunities
  - You might not have as much satisfaction on what you’re doing
  - Engineers are very risk adverse - this is the time to experiment
  - Find what you’re good at, and find out what you love. Sometimes they’re the same.
  - Be willing to take a risk if it’s in and area that you love
  - Regret not doing a startup when younger
  - Took the safe path
