To be announced at Mobile World Congress in Barcelona, MediaTek has filled out its latest generation of phone processors. Positioned under its flagship Dimensity 9400 and premium 8400, the new 7400 and 7400X are optimised for gaming and AI camera processing. Built on TSMC’s 4nm process, both 7400 chips have an octa-core CPU: 4x 2.6GHz Arm Cortex-A78 cores and 4x ...

Smart robot joints include motors, algorithms and EtherCAT
Maxon has launched a range of back-drivable electromechanical joints for humanoid, quadruped and other mobile autonomous robots. The larger HEJ 90 (pictured) is aimed at locomotion, and generates up to 140Nm of torque, customisable up to 180Nm. Maximum joint velocity is 13rad/s. Mechanically, it is 110mm in diameter, 90mm long and weighs 1.96kg. Operation is from 30 to 60V. HEJ ...
Cortex-M23 MCU gets 24bit ΣΔ ADC and firmware over-the-air
Renesas has added a 24bit ΣΔ (sigma-delta) ADC to a 48 MHz Arm Cortex-M23 microprocessor, as well as dual-bank code flash for over-the-air firmware updates. “RA2A2 devices offer multiple power structures and voltage detection hardware to realise energy-efficient operation as low as 100µA/MHz in active mode, and 0.40µA in software stand-by mode,” according to the company. “An independent power supply ...
Software to scan phones for abuse images is itself open to abuse
Software designed to detect child abuse images on smartphones, which could be mandated by governments in some counties, can be covertly repurposed to intrude on personal privacy, according to research at Imperial college. ‘Client-side scanning’ (CSS) is an image analysis technique based on ‘perceptual hashing’, and is mooted as a way to get around the legitimate problem of criminals hiding ...
Smart speaker locates you within a room
A smart speaker can be used to locate you within a room, with no prior knowledge of room shape, according to a University of Illinois at Urbana-Champaign research team. It also, at lease partially, maps the room. It uses the microphone array in the speaker, an Alexa in this case, to provide data for an algorithm that identifies direct and ...
Smart speaker exposé wins Design Museum prize
An exposé of the human labour, data privacy and environmental impacts of a smart speaker wins design award.
Laser hacks hacks smart-speaker from 100m, opens house doors
University researchers have remotely gained control of a home smart speaker using a laser. The hack worked at a range of 110m, and would have been further if the team had had more space. All that was needed was a 5mW laser (little more than pointer-power) and a telescope (actually a telephoto lens). 60mW was sufficient to affect phones and tablets. ...
Wiltshire council expands Telensa Planet smart street light system
Telensa Planet (stylised PLANet), an intelligent street lighting system, has been selected by Wiltshire county council to be expanded with an additional 7,000 lights across the county. The established deployment controls 35,000 lights, and paid for itself in six years through reduced energy and maintenance costs, Telensa says. The controls are also being upgraded as part of a broader LED ...
Smart pill from Cambridge Design Partnership takes sample en route
Aiming at improved dog food,Cambridge Design Partnership has created a smart pill for dogs that both senses and samples. Mars is the customer, and trails were at the Waltham Centre for Pet Nutrition in Melton Mowbray. “It was certainly an unusual request and a major challenge,” says Will Bradley, who led the project for CDP. “Mars Petcare wanted to find out ...
Isolated 700mA quad smart switches aimed at industry
Silicon Labs is aiming at switching industrial loads with a family of quad 24V 700mA isolated 145mΩ switches for resistive or inductive loads – solenoids, relays or lamps, for example, in programmable logic controllers (PLCs). “The switches are capable of providing up to 0.5A of IEC61131-2 compliant continuous current in a quad channel configuration,” said the firm. “Each switch has ...
