Yowza.By this time next week, we’ll finally have seen Porsche’s long-awaited Taycan electric sedan. Ahead of time, there are new details still spilling out about the electric car, and this tidbit is one for the power-hungry driver.Per a drive preview from Autocar, the range-topping Porsche Taycan supposedly sports an overboost function that will help the car produce over 700 horsepower for a period of time. That’s Dodge Challenger Hellcat territory, minus any engine emissions. Reportedly, this range-topping car will be split into Taycan Turbo and Taycan Turbo S designations — a goofy nomenclature considering there are no turbos onboard, but I digress.The overboost function activates for 2.5 seconds to unlock 700-plus horsepower and supposedly helps send the electric car from 0 to 60 mph in under 3 seconds. Porsche has long been keen to point out the Taycan will absolutely house the company’s spirit and performance, and so far, the German marque appears to be delivering.It’s likely the overboost function played a key part in the car’s 7:42 Nurburgring Nordschleife run. While the lap time didn’t set any overall lap records, it is the fastest four-door electric car around the 12.8-mile circuit. Porsche also showcased the fact its upcoming electric sedan can go from 0 to 124 mph and back in just 10 seconds — multiple times in a testament to the battery-electric powertrain’s grunt.Without the overboost, we’re likely looking at around 600 hp for the range-topping Taycan along with a 300-mile range. Expect other models to fill the lineup with less performance and shorter ranges. We’ll have the full details when Porsche is ready to show the car off in September.

Sono Typically, if you had moss in the interior of your car, that would be considered a bad thing. That’s not necessarily the case for this small, solar-powered electric vehicle from German startup Sono.The Sono Sion uses the moss, which is covered with a transparent panel, thankfully, and according to a report Thursday by Electrek, it’s part of the Sion’s cabin air filtering system. Unlike the moss inside Goodyear’s Oxygene tire concept, this moss has kicked the proverbial bucket, but because of its structure, it’s still a good filter.The Sion was conceived as a low-cost EV and debuted back in March with a 35 kilowatt-hour battery and a body covered in solar panels, but this is the first we’re seeing of its interior. The rest of the passenger cabin is pretty sparse, with a small digital instrument binnacle in front of the driver and a Tesla Model 3-like central screen sprouting from the dash.Enlarge ImageIn addition to the mossy dash, the Sono Sion is slathered in solar panels to help keep its 35 kWh battery topped up. Sono The Sion was initially marketed for the low, low price of $18,000 but — and this might be a little shocking (pun intended) — the battery pack costs extra. That is estimated to cost an additional $10,500 if bought outright, or there would be a monthly fee. I know that sounds weird, but it’s not unheard of in Europe — the Renault Zoe is sold this way.It’s unlikely that we’ll ever see the Sono Sion on our roads here in the US, but the company says it should enter production for Europe sometime in the latter half of 2020.

Biometric door lock – uses your fingerprint to open – runs off batteries and has key for emergencies Inexpensive print reader for PC security – comes with software – connects to computer via USB port The second most popular device, which has actually been on the market and in use longer, is the hand reader. This device works by measuring the dimensions of your hand – normally the fingers.Everybody has different length fingers. Even if you do run into someone with similar finger length, the combination of various finger lengths essentially eliminates the possibility of false identification. For example: your index finger might be the exact same length as somebody else’s, but the chances that 2 of more of your fingers are the same length are vanishingly small.Backlighting and lasers were used in early models but now electrical conduction is the method of choice to measure fingers – fewer technical problems, lower power requirements.It works by measuring the electrical conduction of your hand. The user places his or her hand on a metal or plastic plate with two or more studs protruding for finger alignment. A second later the device detects a small current at the point where the hand touches the plate. It then measures these areas and compares the findings to an internal database. Unlike fingerprint scanners, hand readers do not require a computer – needed processing is done internally – although some can be connected to a computer for time clock applications via a standard network connection or serial cable.Most units also have a keypad for entering in user data and ID numbers. Available models can store from 50 to over 500 individual hand measurements.This technology also presents some false positives from time to time when users fail to correctly locate their hand on the scanner plate. Many require the keying of an ID code to make identification 100% positive.These units tend to be very robust and ideal for users with dirty or worn hands like factories and assembly plants. Their self-contained nature means they can be installed virtually anywhere.To Be Continued … (in part 2: Eye Scanners, Face Recognition, and Pattern Recognition) Copyright 2005 PhysOrg.com Like any relatively new technology there are problems: Finger prints can be covered by callus or worn smooth from heavy use -dirt can get into the print lines and skin can peel – all making print reading more difficult. Some users have problems with less expensive models due to the lack of a well defined center whorl in the middle – something the device needs to find the center and build a code for the print. Since prints are converted to number codes it’s possible for two prints to have the same code. This means each device is limited as to the number of prints it can read without giving a false positive. More money usually gets you models that manage more prints.A new technology that scans the subsurface of your fingerprint – down five skin layers deep – works even when the print is scuffed or dirty. This technology is still new, however, so most fingerprint scanner systems also require a code or PIN of some type to for 100% positive identification.Some fingerprint readers and their applications: Print reader with magnetic card reader for extra security.Hand Scanners The basic reason is simple: biometrics uses body measurements to make positive personal identification without resorting to ID cards, passwords, PINs and other problematic security technologies. Your ID is your body – or a part of it, anyway. This makes ID counterfeiting much more difficult and also insures that ID doesn’t get left behind – short or a very serious mishap, that is.Various technologies have been used over the years and favorites are slowly emerging – along with a host of ethical and privacy issues.Finger Print ScannersThe most common technology in use today by far is fingerprint scanning. This technology is used everywhere from top secret military installations to supermarkets, cell phones and time clocks.Police departments have long used finger prints to track criminals because of their uniqueness – each finger print is different – making positive identification possible for any given individual. Finger print readers use this uniqueness to generate a code – rarely do they actually use the full print for identification – based on areas where line print lines merge, fork or loop – like the round “whorl” you can find in the middle of all finger prints.These devices work by scanning the print with a light source – either a laser or, more commonly, a LED (Light Emitting Diode) – on to a chip. The chip is either a CCD (Charged Couple Device – the same found in digital cameras) or the less expensive CMOS (Complementary Metal Oxide Semiconductor). Integrated circuits then generate the code to identify the print.This code is stored in a database – either in a remote computer for cheaper USB models or in the device itself. When a person scans a print, this device compares the code generated by the print with one in the database to make a positive identification. These “print coding” algorithms are closely guarded secrets.Price is probably the most attractive reason to use this technology. Securing your computer with a fingerprint reading mouse cost less than $100. Time clock systems start at around $500. This makes finger print scanning one of the most affordable of all the biometrics technologies.

A recent survey of IT managers by security company GreenBordershowed that most of the malicious code they have to clean from computers resulted from mobile users bringing back “souvenirs” or from user behavior, such as downloading bad software.There are ways to help protect your business from human error. “It’s a two-pronged approach: education, and protecting [employees] from themselves. You need to educate [employees] about clicking on e-mail attachments and downloading software, [and] you need to have the appropriate security software on their computers,” says Laura Yecies, general manager of Check Point Software Technologies’ recently acquired Zone Labsdivision, a consumer and SMB network security provider.A security suite should be installed on every laptop your mobile workers use. Employees should be instructed in proper user behavior. Points to mention include not using work e-mail for personal use, not installing peer-to-peer networking software or any other un-authorized programs, and not plugging gadgets like PDAs into work computers. Software is available that allows you to place usage restrictions on your server or block certain sites from employee access at work. A comprehensive technology and internet security policy is a good start, but also be sure to update the policy and keep employees trained and informed.
