November 13, 2012: "Gravitational Reference Technologies for Precision Navigation and Control in Space " by Karthik Balakrishnan & Andreas Zoellner, Stanford University

Abstract:The Space Gravity Group at Stanford is currently working on a Modular Gravitation Reference Sensor (MGRS), a drag free sensor which enables advances in Earth science and precision distributed Earth-observing sensors, as well as space science, precise orbit determination and maintenance, and precision spacecraft formation flying. During our talk, we will describe the MGRS, and give more detail on two sub-systems, the Differential Optical Shadow Sensor (DOSS) and UV-LED based charge control. Precise control over the electric potential of an electrically isolated proof mass is necessary for the operation of an MGRS. On orbit charging caused by cosmic rays, as well as during caging and uncaging of the proof mass, leads to an electrostatic attraction between the proof mass and its housing. We will show how AlGaN UV LEDs are used to control proof mass potential on an spherical proof mass in an MGRS-like configuration and will provide a look ahead to an upcoming technology demonstration mission of UV LEDs. The DOSS is used as a high precision, compact, low-cost displacement sensor in the MGRS. We will describe how the sensor detects external disturbances by measuring relative motion between the proof mass and spacecraft, with a performance goal of 1 nm at 1 mHz. The DOSS then feeds this signal to the spacecraft control system to maintain a geodesic orbit. We will finally describe a proposed drag-free CubeSat mission built around the MGRS.

May 08, 2012: "Dipoles for Dummies (as well as all the rest of us without a PhD in electromagnetics)" by Henry W. Ott, Henry Ott Consultants

Abstract: An understanding of basic antenna theory would be helpful for all engineers, especially those involved in EMC. After all, if a product radiates (or is susceptible to RF energy) it is an antenna, even if you prefer to call it something else - such as a microprocessor, an IC, a PCB, a power cord, or an USB cable.

This presentation is a simple, insightful, and intuitive discussion of how a dipole antenna works, and how the operation is related to the commonmode radiation from a product. Attendees will end up with an understanding of dipole antenna theory, and know why dipole antenna theory is so important to EMC engineering. All of this is accomplishedthout using mathematics or writing a single equation.
