Rinspeed Microsnap shrinks down for CES 2019

first_img Share your voice Concept Cars Electric Cars Auto Tech Rinspeed MicroSnap is a tiny, do-it-all electric pod Self-driving cars Last year at CES 2018, Rinspeed showed off its wild Snap concept, which blended autonomy with a hot-swappable “skateboard” platform. Rinspeed must have invented a shrink ray in the last year, because at CES 2019, it’s a fair bit smaller.Say hello to the Rinspeed MicroSnap, the latest concept from the wild minds behind the Swiss vehicle design house. Building on last year’s Snap, the MicroSnap shrinks the whole concept down to the size of a Renault Twizy, a European-market electric two-seater. Like its big-boy brethren, the MicroSnap’s platform is meant for fast swapping of the pods on top, which can be used to transport people or goods, depending on need.So why shrink it? Rinspeed says it’s to accommodate the explosion of online ordering, including fresh groceries. By making its concept small enough, the MicroSnap can focus on targeted deliveries that ensure fresh food arrives fresh. That idea works for human transportation, as well, offering direct routes without wasting time dealing with multiple parties.Enlarge ImageIt’s ready for both work and play, just not at the same time. Rinspeed “Customers increasingly want prompt deliveries and many passengers are unwilling to use shared taxis, which have to take time-consuming detours by design,” said Frank M. Rinderknecht, owner of Rinspeed, in a statement.Rinspeed never stops at the design stage with its concepts. The MicroSnap has been thought through from soup to nuts. It can display digital license plates, and the exterior lights use different colors to communicate different concepts to pedestrians. The human-transport pod can track a rider’s health and change the interior lights to improve the mood. There’s a 49-inch curved LED screen offering interaction for riders. There’s even an iris scanner to recognize occupants. It’s also 5G-capable, because of course it is.As you might expect, the Rinspeed MicroSnap is entirely electric. All the wear-and-tear components are relegated to the “skateboard” platform at the bottom, and Rinspeed says that they can be swapped in and out relatively quickly. As for the actual pod swapping itself, Rinspeed also create a robot assembly that uses articulating arms to remove and replace pods depending on what the concept needs to do next. It’s some real pie-in-the-sky stuff, but that’s what CES is all about. 2020 BMW M340i review: A dash of M makes everything better More From Roadshow 2020 Kia Telluride review: Kia’s new SUV has big style and bigger value Self-driving cars: Stay up to date on all the latest news in autonomy.CES 2019: Check out our favorite gadgets from the show in this constantly updating gallery. 0 Post a comment 41 Photos CES 2019 2020 Hyundai Palisade review: Posh enough to make Genesis jealous Tagslast_img read more

How dogs can walk on ice without freezing their paws

first_img Explore further Scientists in Japan have solved a long-standing veterinary mystery: how dogs can stand and walk for so long on snow and ice without apparent discomfort, and without freezing their paws. Scientists at Tokyo’s Yamazaki Gakuen University wondered why dogs do not seem to feel the cold in their paws, even though the paws have less insulating fur than their trunks. The paws have pads containing a high fat content, which freezes less easily than other tissues, but they also have a high surface area-to-volume ratio, which means they should lose heat easily.In humans exposed to frigid temperatures, vasoconstriction occurs in the extremities to reduce the blood flow and resultant heat loss, and ensure the blood returning to the rest of the body does not cool too much. The research team, led by Dr. Hiroyoshi Ninomiya, used a scanning electron microscope to study the paws of four adult dogs, and discovered that the arteries supplying blood to the pads had networks of numerous small veins, or venules, closely associated with them, and that the system essentially acts as a counter-current heat exchanger. When warm blood arrives in the paws via the arteries, heat is transferred to the venules closely associated with the arteries, thus ensuring the blood has been warmed up before it returns to the rest of the body.The counter-current heat exchange system prevents the body cooling and ensures the paw temperature stays within reasonable limits. The same system has also been identified in other animals such as Antarctic penguins, where it occurs in their legs and wings, and dolphins, which use a heat exchange system in their fins. The Arctic Fox (Vulpes lagopus) was already known to have a counter-current heat exchange system in its paws, along with numerous other adaptations to the cold, but the existence of such a system in domestic dogs had not been previously suspected or identified. The findings suggest that domestic dogs might have originated in a cold climate, in which such a system would have had survival benefits.Domesticated dogs are not all able to withstand icy conditions on their paws to the same extent, depending on their environment (such as habitually living indoors), and the breed. Common tips often suggested to help domestic dogs avoid cold feet in winter is to ensure their pads are not split or injured in any way, and to spray their paws with cooking spray before taking them out in the snow. Frostbite is very rare in dogs, but it can occur.The paper is published in the journal Veterinary Dermatology.
