'Virtual wall' improves wireless security and performance

'Virtual wall' improves wireless security and performance
Fed up of poor WiFi signal? A team of researchers led by Dartmouth College may have finally solved the problem of how to inexpensively improve wireless signal strength for indoor spaces with multiple rooms. The same technology for enhancing office and home WiFi signals can also be used to strengthen wireless security. The research, presented on 8th November at ACM's BuildSys 2017 in Delft, Netherlands, relies on 3D printing to produce a cheap, customised reflector that directs wireless signals to where users need them most.

Robotic 'artist' spray paints giant murals

Robotic 'artist' spray paints giant murals
Robots do many things formerly done only by humans - from bartending and farming to driving cars - but a Dartmouth researcher and his colleagues have invented a "smart" paint spray can that robotically reproduces photographs as large-scale murals. The computerised technique, which basically spray paints a photo, isn't likely to spawn a wave of giant graffiti, but it can be used in digital fabrication, digital and visual arts, artistic stylisation and other applications.

Home health care with the wave of a wand

Home health care with the wave of a wand
Increasingly, health care is moving out of the doctor's office and into the home, allowing greater patient freedom and monitoring, but also giving rise to new security risks. One of the main challenges facing home health technology design is the public's inability to set up a secure network in their home and keep it operational. This can lead to compromised or stolen data, or even potentially hacked devices, such as heart rate monitors or dialysis machines.
