Share Scientists have found a way to equip everyday objects like smartphones and laptops with a bat-like sense of their surroundings. At the heart of the technique is a sophisticated machine-learning algorithm which uses reflected echoes to generate images, similar to the way bats navigate and hunt using echolocation. The algorithm measures the time it takes for blips of sound emitted by speakers or radio waves pulsed from small antennas to bounce around inside an indoor space and return to the sensor.

Share This The FINANCIAL -- Scientists have found a way to equip everyday objects like smartphones and laptops with a bat-like sense of their surroundings.  At the heart of the technique is a sophisticated machine-learning algorithm which uses reflected echoes to generate images, similar to the way bats navigate and hunt using echolocation, according to University of Glasgow. The algorithm measures the time it takes for blips of sound emitted by speakers or radio waves pulsed from small antennas to bounce around inside an indoor space and return to the sensor. By cleverly analysing the res...

Researchers say it could help keep buildings intruder-proof without the need for traditional CCTV. 29 April, 2021 23:01 Scientists have created a tool to equip objects like smartphones and laptops with a bat-like sense of their surroundings. A machine-learning algorithm developed by experts at the University of Glasgow can measure echoes and sounds to generate images and create the shape, size and layout of the immediate environment. Researchers say it could help keep buildings intruder-proof without the need for traditional CCTV, track the movements of vulnerable pat...

Image: Glasgow University The scientists at Glasgow University used the speakers and microphone from a laptop to generate and receive acoustic waves in the kilohertz range, and also used an antenna to do the same with radio-frequency sounds in the gigahertz range, collecting the data as a single person moved through a room. They simultaneously recorded data about the room using a time-...

Media release: WES welcomes £50m Women’s Business Centre election commitment WOMEN’S Enterprise Scotland has welcomed an election commitment to invest £50m in the creation of a Women’s Business Centre. The commitment, announced last week by Finance Secretary, Kate Forbes MSP, comes just four weeks after Women’s Enterprise Scotland launched its 2021 Manifesto for Change, focusing on the critical importance of developing and supporting women’s enterprise as part of Scotland’s future economic prosperity. The WES manifesto focuses on five priority areas for positive change, includ...
