-|Dec 16, 2020|**Acoustic Detection & Localization of an Active Shooter or Sniper** presented by Tony Galaitsis\\ Deranged shooters and terrorist or enemy snipers have been a concern for a long time. Technological advances over the past few decades have used gunfire acoustic information to detect and localize active shooters and snipers in order to prevent or minimize their deadly impact. This presentation reviews the general state of acoustic shooter/sniper detection and localization, based on publicly available information found on the internet (YouTube videos, Wikipedia, manufacturer brochures, and published papers/patents) and some basic geometry.|yes| |

-|Dec 30, 2020|**Career stories** (update). People with careers during which interesting (and now unclassified) things have happened.  Mistakes made, lessons learned.\\ Many of the members of our club have technical and scientific backgrounds.  Some may be interested in presenting to the group important experiments or other developments in their field.\\ For example, in my field of pulmonary disease, the development of the Pneumatic Trough by the Rev. Stephen Hales (1677 – 1761) enabled Joseph Priestley (1733 – 1804) to discover oxygen.  The struggle of scientists at that time to understand the fundamentals of matter makes an interesting story.\\ **John Rudy coordinating** -- ''<color green>WOULD YOU LIKE TO PARTICIPATE?</color>'' -- let John know, email us at ''<color green>info@LCTG.toku.us</color>''\\ //so far, have: Bill Haley, Dan Kleppner, Dick Wagner, George Burnell, Mike Alexander, Smita Desai, hopefully Carl Lazarus// ''<color green>There is room for one or two others -- are you interested?</color>''|yes|

The possibility of collisions is already rather high: Collision warning systems create already more than 1000 warnings per day (!of close encounters between 2 objects – and sometimes this is TOO close – and a collision between two space debris objects, at velocities of 27.000 km/h, creates several 1000 new space debris parts…\\ Satellite Laser Ranging (SLR) has demonstrated during the last years the capability of tracking such debris objects, helping to determine their accurate orbit, and also their tumbling motions – important features if you want to catch an old upper stage, and remove it from space.//</color>''\\ //DrKarl Georg Kirchner is a group leader at the Space Research Institute, Department of Satellite Geodesy, Austrian Academy of Sciences in GrazAustria.//| yes| | +|July 172024|

-|June 22021|Eli Brookner would like to present to the group "Fun Family Talk on Contributions of Radar to Winning WWII" Abstract from Eli:\\ //Radar was in its infancy at the start of World War IIThe British were using radar effectively along their coastline with a network of antennas on very tall towers to warn of approaching German aircraft, but they needed an invention that would allow radars to be small enough to fit on ships and aircraft. They came up with the cavity magnetronHowever they looked to American manufacturing know-how and resources to mass produce this device in a hurry. After turndowns by all the major US firms, a small Boston newcomer, Raytheon Company, came up with a solution and ended up making 85% of all magnetrons used by the allies in the war, and changed the course of the war.// | +|August 142024|
