Summary: The emergence of the Internet of Things (IoT) poses stringent requirements on the energy consumption and has hence become the primary driver for low-power analog and RF circuit design. Implementation of increasingly complex functions under highly constrained power and area budgets, while circumventing the challenges posed by modern device technologies, makes the design of low-power RF CMOS radios ever more challenging. The power consumption of GHz short-range radios such as the ones used in BTLE has been significantly reduced in the last decade, but seems to level off at a few mW. This is still much too high to allow for continuous-time operation and duty cycling the radio is unavoidable in order to reach the tens of µW power consumption required for a multi-year autonomy. Duty-cycling unavoidably introduces some energy overhead that is wasted during turn-on and turn-off times. On the other hand, since there will be many radios that will share the same media, in order to avoid network congestion, the transmit times have to be made shorter by increasing the peak data rate. This results in the energy overhead becoming dominant. The use of PLL-free synthesizer using an RF MEMS frequency reference enables to minimize the wake-up and shutdown times to a few µs and hence minimize the energy-overhead. We will start with an introduction showing the requirements of IoT nodes with a focus on power consumption. We then will present how high-Q MEMS resonators can be used to further reduce the power consumption of low-power radios. After presenting the main features of high-Q MEMS resonators including bulk acoustic wave (BAW) resonators, we will show how several fundamental RF building blocks can benefit from them. Then we will present possible PLL-free transceiver architectures that take advantage of the very low phase noise and feature very short start-up time to greatly reduce the overhead energy.

Summary: Air quality monitoring has been historically left in the hands of local government agencies and the EPA. The size and cost of air quality monitoring systems have limited their number in any given area and enabled only regional and mostly delayed responses to air quality issues and their attendant health consequences. This talk will describe how one at risk Southern California community has joined with the South Coast Air Quality Management District to implement low cost air quality monitoring through a collaboration enabled by an EPA Science To Achieve Results (STAR) Grant. 30 web enabled low cost air quality monitors have been installed within a community of 10,000 seniors and are providing particulate matter measurements to inform their real time activities and help monitor nearby potential pollution sources such as adjacent freeway traffic and power generation plants.

Applying Steady-State Cable Temperature Calculations for Safe Cable Operation 🗓

— Current-Carrying Capacity (Ampacity) of underground-buried cables, Use of power systems analysis software for these calculations.

IEEE PES/IAS Joint Chapter of Orange County
Meeting Date: January 17, 2018
Time: 6:00 PM Networking & Food; 7:30 PM Presentation
Speaker: Victor Andrade of ETAP
Location: Santa Ana, California
Cost: The presentation is free and dinner can be purchased upon arrival, with choices: Chicken, fish, or vegetarian.
RSVP: requested, through website
Event Details: IEEE vTools

Summary: Establishing the Current-Carrying Capacity (Ampacity) of underground-buried cables plays a vital role when figuring out the maximum power, which the cable system can transmit. Equally important is calculating an optimal ampacity in order to operate the cables below their maximum temperature limit. If the temperature exceeds the maximum allowable limit, the reliability and life expectancy of the cable will be shortened. Manufacturers typically publish cable ampacity values at very specific conditions that rarely match actual practice. The Steady-State Cable Temperature calculation determines the operating temperature of cable conductors in a raceway system under a specified loading condition. The calculation is based on the NEC accepted Neher-McGrath approach, which employs a thermal circuit model to represent heat flow situations. We will review hand calculations as well as the use of power systems analysis software for these calculations.

Planning for Large-Scale Multi-Robot Systems 🗓

— Robots navigate autonomously in Amazon fulfillment centers, Multi-robot path-planning.

IEEE OC Computer Society & OCACM
Meeting Date: January 16, 2018
Time: 6:30 PM Networking & Food; 7:00 PM Presentation
Speaker: Sven Koenig
Location: Knobbe Martens Irvine offices
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary: Multi-robot systems are now being used in industry. For example, hundreds of robots navigate autonomously in Amazon fulfillment centers to move inventory pods all the way from their storage locations to the inventory stations that need the products they store (and vice versa). Autonomous aircraft towing vehicles will soon tow aircraft all the way from the runways to their gates (and vice versa), thereby reducing pollution, energy consumption, congestion, and human workload. Path planning for these robots is difficult, yet one must find high-quality collision-free paths for them in real-time. Shorter paths result in higher throughput or lower operating costs (since fewer robots are required). Prof. Koenig will discuss different versions of such multi-robot path-planning problems, algorithms for solving them, and their applications.

Prof. Koenig will also discuss a planning architecture that combines ideas from artificial intelligence and robotics. It makes use of a simple temporal network to post-process the output of a multi-robot path-planning algorithm in polynomial time to create a plan-execution schedule for robots that provides a guaranteed safety distance between them and exploits slack to absorb imperfect plan executions and avoid time-intensive replanning in many cases. This talk is suitable for audiences with some computer science background. A background in artificial intelligence or robotics is not necessary.

Bio: Sven Koenig is a professor in computer science at the University of Southern California.
Most of his research centers around techniques for decision making (planning and
learning) that enable single situated agents (such as robots or decision-support systems)
and teams of agents to act intelligently in their environments and exhibit goal-directed
behavior in real-time, even if they have only incomplete knowledge of their environment,
imperfect abilities to manipulate it, limited or noisy perception or insufficient
reasoning speed.

The Evolution of the Smart Grid 🗓

— underlying causes, changing technologies, business models, adverse effects, disruptions, evolution …

Webinar Date: Thursday, January 10, 2019
Time: 8:00 AM (PT)
Speaker: Steven E. Collier, Director, Smart Grid Strategies
Location: on the Web
Cost: none
RSVP: required
Event Details & Registration:
Summary: Carl Sagan said, “You have to know the past to understand the present”. Most everyone knows something about the emerging smart grid. However, not everyone knows the whole story about how and why the smart grid began. It is not only fascinating, but also useful to understand the underlying causes that led to the emergence and continuing development of a smart grid. It’s all about changing technologies and business models. For a variety of reasons, the foundations of the century old legacy electric grid began to erode in the 1970s during the aftermath of the OPEC oil embargo. Longstanding favorable economics, acceptable reliability, stable monopoly business model, and standard utility operations were adversely affected. During this time, disruptive new technologies began to emerge to produce, store, and manage energy, both on the supply side and the demand side. New business models and new market participants emerged as well. The smart grid will continue to evolve as technology and business models continue to change.
Bio: Steve Collier writes, speaks and consults widely on issues and technologies related to the smart grid. He has worked for more than forty years as a professional engineer, executive, consultant, board member for energy, telecommunications, and consulting companies in the US and abroad, including Houston Lighting & Power, Power Technologies, Inc., Sandia National Labs, C. H. Guernsey & Company, Cap Rock Electric Cooperative, the Institute for Management Development and Change, Util-LINK LLC, and the National Rural Telecommunications Cooperative. He has BS and MS degrees in electrical engineering from the University of Houston and Purdue University respectively. He has served as chairman of the IEEE IAS Rural Electric Power Committee, a member of the board of directors of IAS, chairman of the IEEE Smart Grid Education and Operations Committees.
