As population growth of Metropolitan cities such as the San Francisco Bay Area continue to surge to in record numbers, so are the ever increasing number of commuters, which translates to grid lock congestion on the streets of San Francisco.  With the ridership of public transportation service systems, such as the transit system and buses at maximum full capacity, what is the average commuter to do?

One possible solution was provided at the Pepcom Digital Experience show in San Francisco, where Josh Lam, co-founder of Espin bikes, was displaying his eBike line.

For those commuters who do not need to use the freeway, the Espin electric bike may be the perfect alternative solution to get around town.  It uses no gas, is parking friendly, and is able to zip through the streets where cars cannot.

These bikes, excuse the pun, are “geared” more towards the commuters in mind.

The Espin pedal assist bike contains a 350 watt motor, which starts the motor going immediately once pedaling.  It has a battery capacity of 25 miles per charge (20-40 mile range), which takes about 4-5 hours to charge.  Weighing in at about 47 pounds compared to 60-70 for conventional electric bikes, it goes up to a maximum 28 miles per hour, which means it technically doesn’t need a license since it is not classified as a vehicle, like electric scooters are.

There are five levels of power on the motor.  Zero means manual power or using your feet to pedal (i.e. The “Fred Flintstone” method) and Five meaning that you will most likely be going up a very steep hill.  It can go up San Francisco’s steepest hill, which is about a 32% grade.

The well concealed lithium-ion batteries are made by Panasonic, who also supplies Tesla’s electric vehicles.  They charge up to 500 times and last between two and four years.  You can buy additional batteries when needed.  The balloon tires were targeted for commuters or just people who need to run errands, like shopping for groceries.  The “sporty” Espin were targeted for more of the sports enthusiast, who like heads down cycling.

It comes with an odometer and a rack that can hold up to 55 pounds.

For many commuters who ride a traditional bike to work, they are dripping sweat upon arrival.  With electric bikes, you don’t have to struggle up and climb up a hill using your pedals.  You can cruise in electric mode with no sweat, if you prefer.  You also don’t need to shower immediately after arriving to work.  That saves time, as well.

According to Lam, the company was named after a famous Norwegian Fairy Tale character after “Espen Askeladden”, who was a favorite of Lam’s wife, Yina’s, as she was growing up during her childhood days in Norway.  Espen used creative tactics to conquer battles, always prevailing in the end and typically is able to think outside the box and come up with innovative solutions to problems they encounter, which is why they identified with the name.   It is also a play on words as “E-spin” means electric spin.

From what I understand from electric bike owners is that after owning an electric bike for awhile, they find it difficult to going back to the push and grind of the pedals on the traditional bike.  It’s all about the enjoyment of the ride now.  It becomes even more recreational than ever before but without expending as much energy.

However, for “authentic” bicyclists, who still prefer to pushing the medal to the pedal; its still an option, if they want to ride it that way.

List price: $1888.00

SAN JOSE, MAY 10, 2017 – The grandiose trailer starts off with a female voice narrator as she introduces herself as a “visionary”, “healer”, “protector”, “helper”, “navigator”, creator”, “teacher”, “learner” and even the composer of the powerful orchestral soundtrack. She is “A.I.”.

From the intro, the crowd knew from the very beginning that CEO and founder Jensen Huang’s keynote at NVIDIA’s GPU 2017 conference was not only going to be very special, but groundbreaking and mind bending with a glimpse of the not to distant future of Artificial Intelligence.

A.I. was the dominating theme this year at the conference. There were 600 talks in which 300 of them were about Artificial Intelligence.

This year, the rise of GPU computing is reflected by the number of GTC attendees. It’s attendance has increased threefold in the last five years, to 7,000 attendees. There was an 11X increase in GPU developers over the same time to more than 500,000 today, and downloads of NVIDIA’s CUDA drivers and SDK’s exceeded one million a year ago. This year, Nvidia has taken GTC globally. All the top 15 technology companies are here, as well as the top 10 car companies.

Huang started off his keynote showing the charts of Moore’s Law over the last 30 years, citing that advanced micro processing, with the assistance of Dennard’s law of scaling, utilizing more transistors with a reduced voltage, allowed microprocessor performance by a million times. But now both are at the end of the roads, as once 50% per year in increased performance is now just 10% per year, which is why they created a domain specific accelerator that complements the CPU, as well as creating CUDA, which many believe is Moore’s Law Squared; a speedup over the natural processor performance.

The first demo featured Project Holodeck; a photorealistic VR, combining a shared experience for four avatars from around the world, featuring Huang’s “hyper-car-making friend” Christian from Sweden. Christian was showcasing the new company 1.9-million-dollar hybrid car that he just designed, made of carbon fiber with three electric motors, direct drive and no gears with a combustion engine that has 1,200 horsepower, 680 horsepower of electric drive… and that can run from 0 to 250 in 20 seconds. Huang asked Christian to go into the interior of the car and grab the steering wheel. When he obliged, instead of his hands going right through it like we are so accustomed in today’s VR world, Christian’s hands settled right on top of it, obeying the laws of physics.

When Huang asks to see all the parts of the car, we see them each in every piece scattered in mid-air with thousands of parts floating and then reassembling itself back to its original form.

In the era of machine learning, GPU computing has entered a new era where machine learning has come about; Amazon’s “if you like this, you’ll like this” is an example of machine learning. Software writes software and algorithms write algorithms; thanks to deep learning, powerful GPU’s, with the tremendous amounts of data being generated. Unsupervised learning fills the missing parts of the data where computers automate programs.

A demo compared a pair of simulated Mercedes SLK350’s and a landscape with trees and clouds, one which used deep learning for Ray Tracing and one that didn’t. It was night and day and the Ray Tracing just takes seconds for the encoders to render.

Nvidia’s Research Group has deeply committed itself with A.I. There are 1,300 Deep Learning startups that gets advice and technology and Marketing help from Nvidia, and sometimes even funding. Later in the afternoon on the day of the keynote, $1.5 million was handed out to six companies at the Inception Awards. Even at Huang’s alma mater, Stanford University, the most popular course is not Home Economics, but “Intro to Machine Learning”, which is taken from all majors across campus.

Nvidia’s biggest news was the announcement of their next level of computer projects, which turned out to cost about $3 billion R&D project, called the Tesla Volta V100. This new architecture was built from the ground up for deep learning, both for training and inferencing.

The company surpassed Microsoft’s ResNet, Baidu’s Deep Speech 2, and even Google’s NMT. It’s made on TSMC’s 12nm FFN, has 5,120 CUDA cores and 120 TeraFLOPs and Tensor Core processors.

Though it’s mainly for A.I., it does unbelievable graphics as shown on the Japanese sci-fi fantasy, “Kingsglaive: Final Fantasy XV” by Square Enix, which was featured as a demo during the keynote. Photographic style transfer also uses deep learning, with deep learning from one style and applying it to another in a matter of seconds.

Huang announced that you’ll be able to find Volta in just about everywhere; in the cloud, data center with a Volta the DGX-1 supercomputer, and in a personal DGX station.

A.I. will soon be revolutionizing transportation. Huang points out that we need to find a way automate so we can keep up with the “Amazon Effect”.

“Everything that moves someday will be augmented by autonomy. We’re enjoying the Amazon Effect. As we buy things, don’t forget we used to go to the store to pick up things but now we expect things to come to us. The number of truck drivers, transportation professionals can’t possibly keep up…”.

“Our environment would be better without parked cars… There are 800 million parking spots in America for only 250 million cars. That’s why we’ve created NVIDIA Drive, a full stack that will deliver full autonomy for cars.”

We now have more than 200 developers using DRIVE PX. This is a 50 percent increase in the past quarter alone. NVIDIA Drive can be used for mapping, as a co-pilot and as your guardian angel, so even when the car isn’t driving you, it should be watching out for you. For mapping and driving, a video that shows how a car makes an HD map and localizes itself within it. This shows how a car scans, detects road features, constructs an HD road map and then locates itself. Huang shows on a video how, even though the test pilot is behind the steering wheel, it cuts to the guardian angel, which tells driver not to proceed because there’s a car coming across the intersecting road running through a red light.

In addition to autonomous cars, Huang mentioned that some of their partners are working on autonomous planes and ships.

Nvidia’s announced Toyota, one of the largest companies in the world, has selected them for its self-driving vehicles. The two engineering teams are working to create their fully autonomous car and put it on the road in the next few years. Toyota chose Nvidia’s Drive PX platform for their self driving cars.

In addition, Xavier DLA, which is the module that goes inside the Drive PX will be open sourced, making Nvidia’s best technology available for everyone. “Our goal is proliferation,” Huang stated.

Huang also discussed robots.

“The robot is the ultimate version of artificial intelligence. It’s going to revolutionize a whole slew of new industries from manufacturing to health care. We know that robotic surgery is able to perform surgeries that we simply can’t imagine. In the future, we’re going to have cybernetics. We’re going to have robots that are connected to parts of our body. We’re going to have tiny robots that’s going to take care of various tasks.”

“Robots, unfortunately, are incredibly hard to do… It has to sense the world… it has to learn from it and and plan and take action, but it has to interact with the world. With a self driving car, a specific objective is collision avoidance. In a case of robot collision detection is essential – your goal is to connect, your goal is to collide…how you collide is very difficult to do…”.

The first robot demo showed, Ada, the robot, at the Berkeley A.I. Laboratory who learned how to play hockey. The robot was trained to shoot an orange plastic puck into a small net repeatedly using reinforcement learning. It is learning in the real world.

“Hockey is not too bad… what if we wanted a robot to do open a door, lift a car, or cooperate with a doctor to do surgery?” “There is no way we can have it learn this way repeatedly in the physical world.”

That is why an alternate universe has to obey the law of physics if you choose, be visually photo realistic that looks like the world, and has to have the ability to learn inside this alternative universe. The one gap with the real world is it needs to operate…and we would need it train it at warp speed – it needs to move faster.

Project Issac was created in a virtual environment as a robot simulator for this reason. It’s named after two Isaacs – named for physics pioneer Isaac Newton and Isaac Asimov, the science-fiction author. Isaac has the input of environmental robots, you can put virtual sensors, actuators, effectors of the robot and it’s connected to the OpenAI Gym.

“If you’re going to train robots using A.I., they’re going to have to do a lot of work to do their tasks. Robots can learn effectively in this virtual environment and you can take what they’ve learned… and you can take this robot and put it in the real world.” With Project Isaac, the first alternate reality virtual robot simulator. makes it possible for robots to learn inside this virtual world and will hopefully bring the future of artificial intelligence and robotics to the real world.”

Whether it’s Ada shooting shooting hockey pucks into a net or Isaac getting a sixty foot putt on a golf course. For Nvidia’s latest architecture, it’s a score!!!

SAN JOSE, CA,  May 8, 2017 – NVIDIA is making VR more immersive, and VR development easier, with the release of VR audio and 360-degree video stitching as part of our VRWorks software development kit.

Released at the GPU Technology Conference, kicking off today at the San Jose Convention Center, the VRWorks Audio SDK provides real-time ray tracing of audio in virtual environments, and is supported in Epic’s Unreal Engine 4. The VRWorks 360 Video SDK addresses the complex challenge of real-time video stitching.

How sound works in space.

NVIDIA VRWorks Audio helps create a truly immersive environment by modeling sound propagation phenomena, such as reflection, refraction and diffraction. And it does so in real time, thanks to the massive processing power of GPUs.

Using NVIDIA OptiX ray-tracing technology, VRWorks Audio traces the path of sound in real time, delivering physically accurate audio that reflects the size, shape and material properties of the virtual environment.

It’s the only hardware-accelerated and path-traced audio solution that creates a complete acoustic image of the environment in real time without requiring any “pre-baked” knowledge of the scene. As the scene is loaded by the application, the acoustic model is built and updated on the fly. And audio effect filters are generated and applied on the sound source waveforms.

The software release consists of a set of C-APIs for integration into any engine or application, and an integration for Epic’s Unreal Engine 4 that’s now available on GitHub.

GTC attendees can visit the VR Village to experience a live demonstration of VRWorks Audio technology, as well as the SDK integrated into OPTIS’ HIM VR design application.

Come hear the difference!

VRWorks 360 Video for Real-Time Stitching

Also at GTC, we’re releasing the first public beta of the VRWorks 360 Video SDK, which enables real-time 4K 360 video capture, stitching and streaming.

Picture perfect: Z CAM’s V1 PRO VR camera system

In addition, we’re demoing an upcoming release of the VRWorks 360 Video SDK that enables real-time stitching in stereo. Using two Quadro P6000 GPUs, the SDK can stitch eight 4K cameras in stereo as demonstrated with Z CAM’s V1 PRO VR camera system.

“The fact that NVIDIA manages to stitch 4K 360 stereoscopic video in real time, making livestreaming possible, changes the production pipeline and enables entirely new use cases in VR,” said Kinson Loo, CEO of Z CAM.

The NVIDIA VRWorks 360 Video and Audio SDKs are available for all developers to download from developer.nvidia.com/vr. VRWorks 360 Video SDK for mono is available now as a public beta. VRWorks 360 Video SDK for stereo will be released soon.

SAN FRANCISCO, CA,  Mar 3, 2017 – The Game Developers Conference®, or commonly known as “GDC”, the world’s largest professional game industry event just ended it’s five day stint at San Francisco’s Moscone Center last week.  There was plenty of activity at the event with all the participants flying from all around the globe to show their wares and to be discovered by scouts, as well as the main sponsors of the Gaming community, including major players, such as Sony, Xbox,  Nvidia, Facebook Oculus, Autodesk, Google, Amazon, Lumberyard, and Unity Technologies, just to name just a few.

Much of tomorrow’s young talent showed up at other off-site places close to the Moscone Center, such as CBS Interactive, who hosted the European Game Showcase.  The developers that attended this event are based in countries far away, such as Vienna, Poland, Barcelona, and Holland. Many of these same designers were participating at Moscone West’s Indie Lounge Megabooth during the conference.  They are hoping to get funding or to be scouted by the Big Leagues.  From what I saw, I think many will be discovered.

A wide assortment of games were being demoed throughout the floor at the European Game Showcase.  Though, I didn’t see all of them, I noticed that they were not violent. For example,  I walked through a country hillside in a quaint neighborhood, I played keyboard sports games, I was an actual pinball trying control myself by racking up points by bumping into bumpers and chutes, and I attended a Monster Prom.  I also went through an interactive VR space station.  They were all quite enjoyable, even with my passion for “Call of Duty” games.

Though, much VR was being demoed on the Expo floor by the major players, I’m wondering if it has died down compared to a year ago.

This years conference marks the 31st edition of GDC, making it the longest-running event of its kind. Presented every spring in San Francisco, it is the essential forum for learning, inspiration, and networking for the creators of computer, console, handheld, smartphone, tablet, mobile, and online games and creators of virtual and augmented reality for games and entertainment.

GDC attracts over 27,000 attendees, and is the primary forum where programmers, artists, producers, game designers, audio professionals, business decision-makers and others involved in the development of interactive games and virtual reality gather to exchange ideas and shape the future of the industry. GDC is produced by UBM Game Network, a division of UBM Americas.

There is nothing more exciting then the multitude of ideas flowing from so many great young thinkers who are so enthusiastic about their projects.  It becomes infectious and encourages great networking opportunities for all of those involved.
