Summary:
With resurgence of AI and machine learning, sensor miniaturization and increased wireless connectivity, ear-level devices are going through a major revolution transforming themselves from hearing devices into multipurpose hearing enhancement and health and wellness monitoring devices. In this talk, I will present examples of such transformation in the areas of hearing enhancement, health and wellness monitoring and hand-free user experience. In the process, I will highlight how AI and machine learning, miniaturized sensors and wireless connectivity are enabling and accelerating the transformation. In addition, I will discuss practical challenges for the transformation today. Finally, I will share an outlook on future directions and opportunities.

Meeting Date: August 23, 2019
Time: 10:00 AM – 12:00 PM
Location: San Diego
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
Jitter refers to deviation from ideal timing in clock and data transitions. In wireline communications, jitter reduces the timing margin available for clock and data recovery (CDR) circuits and poses significant challenges to signal integrity as the data rates march towards 100Gb/s/lane and beyond. In this talk, we first review the basic definitions of jitter and its properties, the relationship between jitter and phase noise, and the effects of jitter on CDR and other building blocks of a wireline system. We then describe the concept of jitter transfer, jitter generation, and jitter tolerance curves, and the methods of characterizing, modeling, and simulating jitter. Finally, we present some recent works on jitter measurement and jitter mitigation techniques that are used to optimize the link performance.

Target Tracking and Data Fusion ๐Ÿ—“

— Distinguished Lecture by Yaakov Bar Shalom

IEEE San Diego Aerospace & Electronics Systems Society
register
Meeting Date: August 12, 2019
Time: 6:00 PM Networking; 6:30 PM Presentation
Speaker: Prof. Yaakov Bar-Shalom of University of Connecticut
Location: San Diego, Qualcomm Bldg Q Auditorium
Cost: Registration is free for all IEEE members and employees of Qualcomm, $5 for others
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
This talk discusses the issues related to information extraction and data fusion from multiple sensors, in particular, from radars. The goal of extracting the maximum possible amount of information from each sensor requires the use of appropriate sensor as well as target models. In these models one has to quantify the corresponding uncertainties. The issues related to data association and multiple target behavior models are discussed together with some practical algorithms and their implementations for Low Observable targets, with an example of early acquisition of a VLO TBM. The fusion of the information from various sources has to account for their uncertainties as well as the interrelationship — cross correlations — between the uncertainties across sources. The “Track-to-Track Fusion” and “Centralized Fusion” configurations are discussed.

Arc Suppression Technology ๐Ÿ—“

— Rethinking Contact Current Arcing โ€ฆ New insights on an old, chronic problem

IEEE Foothill PES and Cal Poly Student Chapter

Meeting Date: September 27, 2019
Time: 7:00 PM Networking; 7:30 PM Presentation
Speaker: Reinhold Henke, Chief Technical Officer for Arc Suppression Technologies
Location: Cal Poly Pomona Bronco Student Center-Perseus Room (Campus Parking $5.00)
Cost: none
RSVP: Not required
Event Details: PSES Event

Summary:
Relays and contactors are literally all around us. Few know that these workhorse switches have a
secret … namely, that few designers, technicians and engineers truly understand the destructive contact current arcing that occurs inside these devices. They are aware of the results of this arcing, however, and endeavor to address the problems with a wide variety of means. True understanding of the contact current arcing, can lead to better solutions. This presentation discusses the arc itself, and why it is so destructive … and also why the hundreds of devices, components, as well as ever larger, heavier and more expensive contactors have only limited efficacy in containing the arcing problem.

Bio: Reinhold Henke is a seasoned, German-trained Electrical/Electronics Engineer backed by over 30 years of professional product design, development and management expertise. He is currently Chief Technical Officer for Arc Suppression Technologies, a venture he co-founded to commercialize the ultimate solution to contact arcing.
In addition, Reinhold is a topnotch engineering consultant, offering ad hoc engineering design and development
services to medical device companies.
Reinhold’s professional experience spans three multi-national corporations as well as several start-up companies.
His accomplished career covers product design and development of high-tech collateral for the industrial,
commercial, consumer, medical and military industries. He is inventor/co-inventor of over 55 US and international patents. Several of his patents represent true “world’s first” breakthroughs, and have generated revenue streams exceeding a billion dollars for his patent assignees (a mix of employers, clients and customers).
Reinhold holds a Dipl.-Ing. (FH) degree in Nachrichtentechnik from the Fachhochschule Duesseldorf, NRW,
Germany (the equivalent of a BS/MS in Electrical Engineering).

Robust Control of Bipedal Locomotion: An H-Infinity Approach ๐Ÿ—“

— the applicability of the H infinity control technique to two different humanoid robots

IEEE San Diego Section Control Systems Society, co-sponsored by the Robotics Society
register
Meeting Date: August 15, 2019
Time: 6:0 PM Networking & Food; 6:30 PM Presentation
Speaker: Dr. Oscar Montano of 2J USA Laboratory
Location: San Diego
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
The study of mechanical legged locomotion has been motivated by its potential use as means of locomotion in rough terrains, but in particular, the interest arises from diverse sociological and commercial interests, ranging from the desire to replace humans in hazardous occupations (de-mining, nuclear power plant inspection, military interventions, etc.), to the restoration of motion in the disabled. For practical implementation, good mechanical design and good modeling, play a very important role in achieving good performance. However, in real world applications bipedal robots are subject to many sources of uncertainty during walking; these could include a push from a human, an unexpected gust of wind, geometric perturbations of terrain height, or parametric uncertainties of non-modeled friction forces. For these reasons, the design of feedback control systems, capable of attenuating the effect of these uncertainties, is critical to achieve the desired walking gait.
This presentation deals with the applicability of the H infinity control technique to two different humanoid robots: the 32 degrees-of-freedom biped robot ROMEO, of Aldebaran Robotics; and the 2D planar biped RABBIT, housed in LAG, the Automatic Control Laboratory of Grenoble. Results, challenges, and state of the art are discussed.

Bio: Oscar Montano has worked in research and development in the aerospace and telecommunications industry since 2008, and is a Certified Labview Developer and Instructor since 2016. He obtained his Master’s degree in Electronics and Telecommunications from CICESE, Mexico, in 2012, and received his PhD degree in Controls Systems, Robotics and Automation from l’Universite de Nantes, France in 2016. He currently works as Electrical Design Engineer at the 2J USA laboratory in San Diego.

He has authored 7 articles in peer-reviewed journals, presented his results at 10 international congresses and written a book chapter. His current research interests include stability analysis, system identification, modeling and robust control of nonlinear systems.
