A new special machine is ready to show

Full video to impact below. When working on cases like this, I always want to bring in the most relevant research, to the specific case, that I can find. In this case, we have a vehicle that is approximately 73 degrees to the roadway with its headlights pointing to the right and the taillights on the left. Jeff Muttart and Swaroop Dinakar (with others), published a paper "The Influence of Driver Expectation when Recognizing Lighting Targets at Nighttime". Figure 1 in this paper shows a vehicle at 70-degrees with headlights pointing right and taillights on the left! The paper discusses the issues of recognizing the fact that the red lights on the left and the white lights on the right are in fact taillights and headlights attached to a vehicle across the roadway. How perfect?!?! https://lnkd.in/gJYsgwmi

And I thought "Cogswell" belonged to the cartoon along with flying cars. This Cogswell Condenser is a century old three-section variable capacitor. It would have been used in a Tuned Radio Frequency (TRF) set. The typical receiver featured three amplification stages with type 01 vacuum tube triodes. Each stage was independently tuned to the broadcast frequency. The TRF radios were not user friendly, as all three dials had to be independently adjusted. The station would not appear until all three were "in the neighborhood." The TRF radios were quickly replaced by single-knob-tuning superheterodyne radios. I don't think you will find a TRF past 1932. Just for fun - if you could be a historical figure, who would you be? Here are a few for your consideration: Alexanderson, Maxwell, Marconi, Tesla, Fleming, de Forest, Armstrong, Franklyn, Sarnoff, Farnsworth, Hertz, Edison, Westinghouse, Shannon, and many other. I admire Armstrong - except for the tragic final chapter. Happy holidays, Aaron #VacuumTube #Radio #RetroTech #History

Thoughts on Detroit and the Battery show #detroit #EV #detroitbatteryshow #batteries Just back from the Detroit Battery show. My first time at the show. It was held right downtown at the Huntington Place, almost right beside the iconic GM building. Last year the show was held at a much smaller venue in Novi, so everyone I talked to seemed to be much happier with this larger venue. Parking was in high demand so ended up parking in Greektown. (I found a small church parking lot that only charged $5 cash instead of $40 closer to the show ??). But now I had to hoof it for a good 20 min to Hutington place. Suddenly the negative images I had been fed from media of Detroit creeped into my mind. Yikes! Had I made a big mistake parking where I did? Now, walking in a three-piece suit in 'dangerous' and 'run-down' downtown Detroit, I would be an easy target for unsavory characters. You can imagine my surprise as made my way along the clean streets and airy open-air restaurants; the place was nicer than downtown Toronto my hometown! Passersby who caught my eye, clearly locals breezing by on their daily errands, but were quick to flash me a smile and a couple even said: "Good morning" and "Have a nice day"! I was shocked. Being Canadian, I have some recollection of hearing that Michigan is a swing stater, but I have no clue as to which party runs the city or the state, but whoever it is they are doing a great job. Keep up the good work! The show was abuzz and well attended. It was divided into two sections, battery manufacturers at one end and peripheries at the other, like battery testing, robotics, laser welding and manufacturing. None of the exhibitors I spoke with seemed concerned with the slowdown in EV roll out. Many of them in manufacturing also sell their equipment into other sectors like medical so they are well diversified. Everyone seemed upbeat and positive about the future. There were a lot of Chinese companies exhibiting. China dominates in Li-ion batteries from the supply and demand side. But under the US Inflation Reduction act, China is deemed a “foreign entity of concern”. Therefore, unlike the Japanese and Koreans, the Chinese have not been quick to set up shop in the US due to this uncertainty. But they have been active in development of overseas mines through equity participation, off-take agreements and other methods. My impression is that the Chinese are focusing on Mexico to enter the US. With this in mind, the most interesting company I can say I met was XING Mobility. They are a Taiwanese company sharing a booth with their Chinese partner and jointly manufacturing in Mexico. Strange bedfellows for sure lol. The Taiwanese are quick to tell you they are, well, Taiwanese. While the Chinese are quick to tell you that Taiwan is part of China ?? It is nice to see people and companies coming together simply to do business, politics be damned! A great event, see you next year...

???? Nighttime driving and vehicle recognition: I watched the video multiple times and, drawing from our research, came to some intriguing conclusions. Despite being familiar with the relevant studies, recognizing the vehicle in the video proved challenging for me and others. This underscores a key point from our research: "If you don’t know what it is, you cannot know where it is." The video perfectly exemplifies this concept. To enhance nighttime recognition, we should consider the CAPLETS factors—contrast, lighting, pattern, eccentricity, time of exposure, and size. These factors play a crucial role in capturing driver attention. In the video, the vehicle lacked adequate contrast and lighting. The arrangement of white front lights and red rear lights didn’t create a recognizable pattern against the background lights. Additionally, when tail lights and headlights are angled away from the observer, they appear dimmer, making them seem farther away (Dinakar, 2018). It’s essential that we focus on these elements to improve nighttime driving safety. Thoughts? ?? #NighttimeDriving #VehicleRecognition #InformationTheory #DriverSafety #ResearchInsights

In this video, students from the University of Maryland demonstrate how a cleverly designed sweater allows a person to disappear from object classifiers. The innovative approach challenges current systems that rely on multiple cameras for identity detection, rendering them ineffective against this exploit.

FREE WEBINAR ALERT! Wednesday, February 5th at Noon MST / 2pm EST. Pedestrian fatalities in the U.S. have surged by 83% since 2009, far outpacing other traffic fatalities and coinciding with the rise of larger vehicle sales. How much of this harm can be attributed to these vehicles? Join Dr. Chris Cherry (Associate Director of CPBS), Saurav P. ,(PhD candidate at University of Tennessee Knoxville), and Dr. Nick Ferenchak (Center Director of CPBS) for an in-depth exploration of how vehicle attributes like weight, size, and age influence pedestrian injury outcomes. Drawing on their analyses of single-vehicle pedestrian crashes in Tennessee and Texas from 2009 to 2024, they’ll discuss key trends and insights. Explore the future of pedestrian safety as vehicle weight and size continue to grow, with considerations for the influence of vehicle age. Register here: https://lnkd.in/gBuDUk4B

Preview of what we are talking about tomorrow

‘Because you’re worth it!’ 2nd days finalised and I can tell you that this is something beyond imagination. What I find almost surprising is how big the difference is between similar industries. Take aerospace as an example: One visitor told me that they’re working with multiple sensors, ranging from FNIRS, to muscle sensors. The current setup requires 3 separate laptops and roughly 2 weeks of manual labor to synchronize the data and get somewhat good outputs. Double that time if you want 2 participants. Quadruple that time if you want 2 participants, simultaneously. The other visitor told me that they rely on simple questionnaires for pilots to answer regarding new implementations (hardware and software). Pen and paper. In terms of feedback about Prophea.X, nobody left our booth without understanding our value. A quick calculation of the time they save, showing that they can potentially double their testing capacity, and have scientist focusing on interpretation and actionability of data instead of cleaning - that’s money right there! Also, this is me and my best impression of mind control, wearing the EEG kit from one of our partners EMOTIV, while Rohit, Joshua and Roland onboard me between the waves of customers! Onward day 3!
