Bluetooth 6.2 gets more responsive, improves security, USB communication, and testing capabilities

Bluetooth 6.2 specification has just been released with a range of new features to enhance responsiveness with shorter connection intervals, strengthen security against amplitude-based RF attacks, and improve communication with a new “Bulk Serialization Mode” that’s especially useful for USB Bluetooth LE audio applications. The new Bluetooth Core 6.2 specification also introduces various BLE Test Mode enhancements. If you feel like Bluetooth specifications are released more often than in the past, that’s normal because the Bluetooth SIG switched to a bi-annual release schedule. For instance, the Bluetooth 6.1 specification was just published last May, or about 6 months ago… Bluetooth 6.2 highlights: Bluetooth Shorter Connection Intervals (SCI) reduce the minimum Bluetooth LE connection interval from 7.5 ms to just 375 µs for faster responsiveness. The change will especially impact high-performance HID devices, real-time human-machine interfaces (HMIs), and latency-sensitive sensors. AR/VR and gaming applications will particularly benefit from the lower latency. […]

Bosch magnetic-field quantum sensors leverage synthetic diamonds, lasers, and microwaves for ultra-precise measurements

Most people have heard about quantum computers, but quantum sensors? I’ve just come across those as Bosch is developing magnetic-field quantum sensors harnessing “the power of quantum physics to enable measurements with unmatched precision” while being much more compact than other quantum sensors using techniques like SQUIDs (superconducting quantum interference device), vapor cells, or optical traps. Bosch Quantum Sensing (that’s the full company name) further explains its magnetic-field quantum sensors surpass the capabilities of conventional sensors by offering a wider measurement range, higher sensitivity, and higher spatial resolution. They currently have an internal quantum sensor prototype/evaluation board that’s about the size of a smartphone, so they are still quite larger than traditional sensors. Bosch quantum magnetometer can measure tiny magnetic field variations with accuracy, including the Earth magnetic’s field, and even analyze the direction of and magnetude of magnetic fields giving the equivalent of a 3D-point magnetic representation. This notably […]

STMicro VD55G1 – A small, low-power global shutter I3C camera sensor for computer vision

STMicro VD55G1 global shutter camera sensor

STMicro VD55G1 is a new global shutter I3C camera sensor with a small die size of 2.7 x 2.2 mm, 804 x 704 pixels native resolution, and consuming about 1mW in its ‘always-on’ autonomous mode to wake up the host when motion is detected. Camera sensors are available with rolling or global shutter, with most from the former type, but as we’ve seen in our reviews of the e-Con Systems See3CAM_24CUG (USB 3.1) and the Raspberry Pi Global Shutter (MIPI CSI) global shutter cameras, the latter is much better we capturing moving objects clearly at high frame rates with fewer artifacts than with rolling cameras. The VD55G1 global shutter sensor will also benefit from the same advantage but is offered in a smaller package working over MIPI CSI and/or I3C, making it suitable for devices with small batteries used in applications such as eye tracking or motion estimation. STMicro VD55G1 […]

Cadence Neo NPU IP scales from 8 GOPS to 80 TOPS

Cadence Neo NPU (Neural Processing Unit) IP delivers 8 GOPS to 80 TOPS in single core configuration and can be scaled to multicore configuration for hundreds of TOPS. The company says the Neo NPUs deliver high AI performance and energy efficiency for optimal PPA (Power, Performance, Area) and cost points for next-generation AI SoCs for intelligent sensors, IoT, audio/vision, hearables/wearables, mobile vision/voice AI, AR/VR and ADAS. Some highlights of the new Neo NPU IP include: Scalability – Single-core solution is scalable from 8 GOPS to 80 TOPS, with further extension to hundreds of TOPS with multicore Supports 256 to 32K MACs per cycle to allow SoC architects to meet power, performance, and area (PPA) tradeoffs Works with DSPs, general-purpose microcontrollers, and application processors Support for Int4, Int8, Int16, and FP16 data types for CNN, RNN and transformer-based networks. Up to 20x higher performance than the first-generation Cadence AI IP, with […]

LiFi 802.11bb standard uses light for in-room data transmission up to 224GB/s

The 802.11bb WiFi-like standard, also called LiFi, was ratified in June 2023. It enables data transmission up to 224GB/s at a few meters range within a room using light instead of RF signals used in most other wireless standards. The technology has been worked on for many years, and we first covered (a version of) LiFi in 2014 that was still part of the IEEE 802.15 standard with speeds up to 1 Gbps. But the Light Communications 802.11bb Task Group was only formed in 2018 chaired by pureLiFi and supported by Fraunhofer HHI, and led to be ratification of the IEEE 802.11bb standard last month. In a typical LiFi setup, you’d have a LiFi-capable router connected to your local network and the Internet, a LiFi-enabled light bulb on a ceiling, and one or more LiFi receivers. From the end-user perspective, it would work like accessing a WiFi access point. We’re […]
