BREAD MAKING ROBOTS MIGHT PUT BAKERS OUT OF THE BUSINESS
Breadbot, the robot that can mix, form, proof and bake ten loaves of bread an hour. The automatic machine starts with dry ingredients and bakes several different types of bread, including white, whole wheat, nine grain, and honey oat.
It even gives signs/alerts to staff to remind them to add more ingredients and to slice the fresh loaves. Breadbot is marketed as a smart green choice for small supermarkets that would normally be buying bread from a wholesaler.
Instead of paying for the transport of loaves, only receive the dry ingredients do fresh baking at the store.
NEW 3D PRINTER PRINTERS 100 TIMES FASTER THAN THE STANDARD PRINTER
3D printing has held out the promise of incredibly efficient and timely small-scale manufacturing but has been held back from widespread use by its slow speed. A new technique developed at the University of Michigan, however, promises to print complex designs 100 times faster than the current printers.
The way 3D printers work is by reading a file of a 3D model and rebuilding the model by laying down resin in tiny lines set down in layers, one on top of the other, till the time the model is constructed.
The bigger the model, however, the more time taking this process becomes, growing exponentially as the model gets wider and taller.
What’s more, if you required to produce many copies of the 3D model, as you would for small scale manufacturing, you would need more machines, often hundreds more, printing out the same item.
Creating a Vat-Printing Solution to the Time Challenge
Burns and Scott tried something unique from traditional printing techniques to achieve their results. Rather than laying out the product a line of resin at a time, they used a pair of lasers to solidify the liquid resin in a vat into the shape prescribed by the 3D model file.
The lasers are able to command where the resin remains liquid and where it solidifies, allowing them to make sophisticated shapes, including a toy boat, a block with the letter M carved into it, and a lattice.
Getting the lasers to print exactly what was appropriate was no small task. Earlier attempts resulted in incomplete solidification of the resin at the window of the vat, where the laser first made contact with the resin.
Gaining Precision control with more lasers
Earlier attempts used only one laser, so Burns and Scott tried adding another laser, using a different wavelength to command the rate of resin flow and were able to get 3D control of resin hardening close to the vat window, whereas previous vat-printing approaches were restricted to a 2D plane.
“It’s one of the first true 3D printers ever made,” said Burns.
Patents have been filed for the different techniques used in the process and Scott is planning a commercial venture based on their work.
Mobile App That Warns Its Residents When an Earthquake Is Happening
Residents in the Los Angeles County can now be better informed about earthquakes with the launch of the app ShakeAlertLA.
This mobile app uses US Geological Survey’s (USGS) early warning sensor network to indicate when an earthquake of 5.0 magnitude or larger is about to shake their location.
The Los Angeles mayor, Eric Garcetti says that even a few seconds warning is enough time for residents to take cover, stop their vehicle, exit an elevator or simple drop and hold on.
The app is available on google play and app store also. Public Service Agencies along the West coast have been utilizing the USGS’ early warning sensor network since October; there isn’t any technology currently available that can alert residents over the whole region.
The app is currently only available to Los Angeles County but Richard Allen, director of the Berkeley Seismological Laboratory hope that the app’s coverage will increase.
One of these services is the Bay Area Rapid Transit system. BART is associated to ShakeAlert when the system sends out alerts the BART will automatically paste and adjust its services and individual trains to mitigate potential accidents or derailments.
Existing warning systems are too slow. The recently created Presidential Alert which sends a text message to all turned on phones within range of a cell tower was slow to get by some users says Allen.
The purpose of the early warning is to get people into that safe place before the shaking starts instead of once the shaking starts.
