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 ...

MediaTek has announced some details of its Dimensity 7200 phone SoC. To be built on a 4nm process from TSMC, it will have eight Arm cores: two 2.8GHz Cortex-A715 cores and six Cortex-A510, then MediaTek’s own AI processing pnit (APU) and an Arm Mali G610 GPU. Memory runs at 6.4Gbit/s and there is UFS 3.1 for storage. For gamers, there ...

Imagination Technologies is aiming at phone-based gaming with scalable GPU intellectual property that can implement hardware ray-tracing. Called IMG DXT, and part of a planned ‘D-Series’ family, the GPUs “offers mobile device manufacturers the chance to integrate ray tracing into their SoCs, to match their design goals from premium to mainstream devices”, according to the company. The GPU scales from ...

Rohm has created a reference design for an automotive-grade wireless phone charger with NFC communication, using the Qi standard and supporting EPP (extend power profile) – supplying up to 15W. It combines Rohm’s automotive-grade wireless power transmission control IC (AEC-Q100 qualified BD57121MUF-M) with two STMicroelectronics’ chips, and NFC reader (ST25R3914) and an 8bit microcontroller (STM8A). NFC communication is included for ...

Using only resources built into a phone, University of Washington researchers have developed an app that uses inaudible sonar to monitor someone’s breathing rate, and can deduce when drug overdose has stopped breathing. Called Second Chance, it is claimed to detects opioid overdose-related symptoms ~90% of the time, and can track someone’s breathing from up to ~1m away. “Here we ...

The UK’s national research centre for 5G mobile commucniations being built at the University of Surrey is to be part of a European project to develop millimetre-wave radio technologies for next generation cellular mobile networks. The European Commission-funded MiWaveS project will investigate the use of millimetre wave (mmW) small cells in dense urban areas to make more efficient use of the radio spectrum by deploying low-power access points ...

The PC was a 35 year golden bonanza for Wintel, but the mobile phone business has spread its largesse more spasmodically – first Motorola, then Nokia, then Blackberry, then Apple, then Samsung. Could the bonanza be over?

The Prime Minister has joined the rest of us in getting fed up with ‘not-spots’ – areas where you can’t get a mobile phone signal.

The Prime Minister has, so it is said, joined the rest of us in getting fed up with ‘not-spots’ – areas where you can’t get a mobile phone signal.

Can there really be soaring demand for 3D packaging? That’s what AMS says, and it’s backed up the claim with €25 million to establish a production line for it.
