Mercedes F1 to use Qualcomm 5 GHz WiFi for its tire data

In Formula 1 you need more of everything. More speed, more grip, more hospitality, more money. And you need data, reams and reams of data. The Mercedes-AMG Formula 1 team – the guys with the silver cars driven by 2015 F1 champion Lewis Hamilton and his teammate Nico Rosberg – need so much information that they've teamed with Qualcomm to wirelessly upload thermal imaging data of its tires. During a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Live telemetry has been a feature of Formula 1 for 20 years, though there are more restrictions on it than in the past. (In the days leading up to last weekend's United States Grand Prix in Texas, Formula 1 major domo Bernie Ecclestone said that F1 needs to cease being an engineering war and return more responsibility to the drivers.) Nevertheless, F1 teams gather vast amounts of data during a race weekend, particularly in practice sessions during which restrictions on what they can upload from cars – from engine/power unit parameters to aerodynamic loads – are less prohibitive. For example, during a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Mercedes F1 technical director Paddy Lowe points out that the standard telemetry system simply doesn't have the bandwidth to handle the thermal tire imaging data that the onboard thermal cameras generate. Why do you want a thermal video of the tires? Because it tells the engineers and drivers precisely how much temperature there is across the surface of a tire during a lap, in corners and on the straights. It also indicates how quickly the tires come up to temperature and when they potentially overheat. Understanding the temperature variations allows the team to set the cars up optimally for grip and tire life during a stint. Qualcomm's system works with the race cars like this: Each car has forward- and rear-facing cameras in a winglet mounted on the left side of the engine intake behind the driver's head, which continuously record thermal images of the tires. As a Mercedes enters the pit lane, it passes a Qualcomm 802.11ac WiFi receiver to which it uploads the thermal data. As the car nears the garage, another receiver takes over the upload. Several Qualcomm Snapdragon 805 processors crunch the raw data as it uploads. The data is encrypted – there are always prying eyes in Formula 1.

Queens man knows how to party, disrupts Mets game with van

A New Yorker and all-around true American hero took his weekend festivities a little too far and landed himself in front of a judge last week. According to NBC New York, Nelson Hidalgo drove his unassuming Sprinter to Citi Field on Saturday, June 18, around 10:45 p.m. While the Mets were getting thrashed by the Braves, Hidalgo pulled up to the intersection of 127th street and 35th avenue. Hiding within the van's cargo area were 80 speakers driven by powerful amps, around $20,000 worth of car audio. Hidalgo opened the Sprinter's rear doors, deployed his amazing speaker system, cracked a cold Coors Light, and unleashed hell. Noise complaints immediately started flooding in to the police, including one from the Mets' bullpen. Soon, Hidalgo amassed a sizable crowd who had come to rock out and marvel at the lunacy of the Sprinter's sound system. The NYPD showed up eventually and, undaunted by noise and the crowd, clapped the irons on poor Nelson. The Sprinter was impounded and Hildago was charged with second-degree criminal nuisance, general noise prohibition, disorderly conduct, and obstructing the driver's view. "I know it's illegal, but it's the weekend," he explained to the cops as they hauled him away. Once they had him in custody, the NYPD realized that Hidalgo was the person they had been looking for in connection with absurdly loud music coming from various city junkyards in the dead of night. Hidalgo, who has no prior record, spent the night in the slammer but was released the next morning with no bail on the promise that he return for his court date on August 1. Related Video:

Chicago Car2Go app reportedly hacked, some 100 cars missing

Car2Go launched in Chicago in the summer of 2018, with 400 Daimler cars rolled out on the Windy City streets soon after. But that big fleet just took a big hit: The car-sharing app has now reportedly been hacked, and some 100 cars have been stolen as a result. CBS Chicago is reporting that some of the missing cars have been used to commit crimes. It is yet unclear what the hacking has exactly enabled the perps to do, but the compromised app appears to have opened the doors and given the thieves free rein with easily stolen cars. Within Chicago, there is a 29 square mile area where the vehicles were supposed to be dropped off, but they haven't been limited from exiting that zone at any point. The Chicago Car2Go fleet started out with Smart ForTwo cars and bigger Mercedes-Benz CLA/GLA models; we can imagine the ForTwos are a touch slight for any ram raiding, but an escape car that can vanish in a crowd of other shared Smart cars seems handy for misuse. To address the matter, Car2Go froze its Chicago operations today, saying it is "neutralizing a fraud issue and working together with law enforcement." No personal or confidential user info is said to have been compromised. CBS Chicago's Brad Edwards tweeted today that 12 people have been taken into custody so far, with the story developing as we speak.
