According to the definition established by the US Food & Drug Administration (FDA), medical implants are devices or tissues that are placed inside or on the surface of the body. Many implants are prosthetics, intended to replace missing body parts. Other implants deliver medication, monitor body functions, or provide support to organs and tissues. Implants can be placed permanently or they can be removed once they are no longer needed. For example, stents or hip implants are intended to be permanent, while chemotherapy ports or screws to repair broken bones can be removed when they are no longer needed. Due to the risks associated with surgical complications, infections, foreign body rejection, allergic reactions, and other life-threatening issues, the great majority of medical implants are heavily regulated by the FDA with Class III designations. Since the early days of the development of biomedical implants, biocompatibility of materials and safe device operations inside the physiological environment have been identified as the single most important deciding factors for successful deployment. This presentation focuses on the findings and potential approaches on packaging for implantable biomedical devices, with specific examples cited from implantable neural probe arrays.

Bio: William C. Tang, Ph.D. received his BS, MS, and Ph.D. in Electrical Engineering & Computer Sciences from the University of California at Berkeley in 1980, 1982, and 1990, respectively. His seminal thesis work and invention on the electrostatic comb drive has become a crucial building block for many microactuator and microsensor research in the field, and was, and continues to be recognized internationally as one of the most influential and foundational work. Since his graduation, he continued his contribution to the MEMS field first in the automotive industry as a Research Senior at Ford Research Laboratory in Dearborn, Michigan, and as the Sensor Research Manager at Ford Microelectronics, Inc., in Colorado Springs, Colorado. In 1996, he joined the Jet Propulsion Laboratory, California Institute of Technology, where he was the Supervisor of the MEMS Technology Group, leading the pursuit of MEMS technology for space applications.

Dos and Don’ts of Lighting Design and Controls 🗓

Meeting Date: Thursday June 15, 2017
Time: 6:00 PM Networking & Dinner; 7:30 PM Presentation

FIRST Speaker: Ms. Lyn L. Gomes, P.E., CCP, LEED AP, CLCATT
SECOND Speaker: Mr.Rick Miller, PE, LEED AP, LC, CLCATT

Location: Santa Ana
Cost: The presentation is free and dinner can be purchased for $30 upon arrival, with choices: Chicken, fish, or vegetarian.

Event Details: IEEE Event
Lyn and Rick will present their recommendations for lighting control system design and commissioning for new construction and existing buildings. They will provide practical guidelines for designing a lighting control system that can be applied immediately. Implementing their recommendations will result in fewer RFIs, prevent inappropriate “or-equal” submittals, that can be programmed successfully so they have a fighting chance of passing testing. They will share their lessons learned, discuss the use of the Title 24 forms as a checklist for design, provide recommendations for daylighting and occupancy sensors, how to prevent issues that crop up during commissioning (i.e. functional testing), and the difference between a control intent narrative and a sequence of operations. This presentation is geared towards engineers/designers of lighting control systems and commissioning providers.

Ms. Gomes is the lead Commissioning Authority for kW Engineering. Her 15 years of combined experience in HVAC design, construction, and startup make her a triple threat in the world of commissioning.
Mr. Miller has designed lighting and power systems for architects, engineers and builders for nearly forty years. Rick is the principal co-author of the California Lighting Controls Training Program (CALCTP), and trains electricians how to install lighting controls.

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

— (PES/IAS) – ampacity, limits, reliability, life expectancy, raceways, loading, heat-flow …

Meeting Date: Thursday, April 20, 2017
Time: 6:00 PM Networking & Dinner; 7:30 PM Presentation
Speaker: Victor Andrade, Applications Engineer, ETAP

Event Details: IEEE Event
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 reduced. 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 and also the use of power systems analysis software for these calculations.

Bio: Mr. Victor Andrade received his Bachelor’s degree in Electrical Engineering from California State Polytechnic University in 2007. At ETAP, Victor is the Applications Engineer responsible for supporting the Gulf Region accounts. Victor’s previous duties included the review of power system studies, ranging from Power Flow, Short Circuit, Protection/Coordination, Arc Flash, Harmonics and Transient Stability. Before joining ETAP, Mr. Andrade worked as a technical support engineer for SKM Systems Analysis, Inc., implementing software testing and V&V procedures, and creating CAPTOR protective device library models.

Gallium Nitride Power MMICs: Fact and Fiction 🗓

— (Buenaventura Section) – Efficiency, output power, low loss, thermal, issues …

Summary: Gallium Nitride (GaN) based transistor technology’s characteristics of very high current density combined with high voltage operation have held promise to vastly improve many microwave circuit applications that presently utilize Gallium Arsenide (GaAs) devices. Today, GaN transistors are capable of high voltage operation while simultaneously demonstrating fT & fMAX characteristics more typical of lower voltage GaAs PHEMT devices. The potential benefits of GaN device characteristics combined with monolithic microwave integrated circuit (MMIC) technology are many. Highly efficient switched modes of power amplifier operation should be possible at higher output power levels and frequency. High output impedance typical of transistors operated at three to five times the voltage of GaAs should facilitate lower loss matching networks due to the reduced transformation ratio. Alternately, transistor periphery and corresponding output power could be dramatically increased while maintaining impedance transformation ratios similar to that of existing GaAs PHEMT amplifiers. The higher output power density of GaN devices should lead to greatly reduced die size for GaN implementations of existing power amplifier functions. The improved heat flow realized by the high thermal conductivity Silicon Carbide (SiC) substrate material should allow for acceptable junction temperatures even with the much higher power dissipation. Very high power switches could be designed by using large control voltages and taking advantage of the high current capability (high Imax) of GaN. While the advantages of GaN are manifest, many of the features that make GaN transistors attractive can be shown to create significant issues that are typically not encountered with lower voltage technologies. In this talk, examples and scenarios are discussed highlighting the benefits and issues associated GaN MMIC technology.
