RoboSense EM4 Ultra-Long-Range Digital LiDAR

RoboSense (Shenzhen, HKEX 2498.HK) EM4 is the first product on the new digital EM platform and the world's first 'thousand-line' ultra-long-range digital LiDAR: up to 2160 lines, 600 m max range (300 m @10% reflectivity), 120x27 deg FOV, 41.04M pts/s single return; built on the self-developed SPAD-SoC fully digital architecture with 60% lossless data compression, resolving small distant objects such as tires, cones and paper boxes and extending ADAS response time by up to 70%. Also serves long-range avoidance, high-definition perception and mapping for inspection robots and unmanned vehicles.

Ouster OS1 Max Rev8 256-Channel Long-Range High-Resolution Imaging Lidar

Ouster OS1 Max Rev8 256-Channel Long-Range High-Resolution Imaging Lidar

The Ouster OS1 Max is the flagship long-range imaging lidar of the Rev8 OS series and the first to reach 256 vertical channels (also 64/128): 865 nm Class 1 eye-safe laser, 360 deg x 43.9 deg FOV, 512-4096 horizontal columns, 5-40 Hz configurable rotation. In 1024 @ 10 Hz mode it reaches 350 m on 80% Lambertian targets and 200 m on 10% targets (both >90% detection probability at 100 klx sunlight), with 500 m max representable and 0 m minimum range; range accuracy is +/-1.25 cm (Lambertian) / +/-2.5 cm (retroreflective) at 0.1 cm resolution, up to 2 returns and 10,485,760 points per second. Native RGB-D color point cloud (116 dB dynamic range) carries RGB, range, signal, reflectivity, NIR, channel, azimuth and timestamp per point; a synchronous IMU runs at 640/1280/2560 Hz. Data leaves over gigabit Ethernet UDP with PTP/gPTP/NMEA/PPS time sync (<1 ms error) and <10 ms latency. It runs from 12/24 VDC (9-58 V) at 15-25 W (19 W nominal, 28 W peak starting at -40 C), measures 87 mm diameter x 82 mm and weighs 670 g (720 g with halo cap); IP68/IP69K, -40 to +85 C, 100 g shock and 10 Grms vibration. Engineered for functional safety (ASIL-B, SIL-2, PLd) with an on-sensor 3D Zone Monitor and designed for cybersecurity to ISO 21434 / UNECE WP.29 / IEC 62443 / ISO 27001. Built for long-range industrial sensing, off-highway vehicles, autonomous cars, trucks and buses, traffic and security monitoring, and 3D mapping vehicles.

Bothlent XFM-10X21-MINI Acoustic Noise Reduction Module

The XFM-10X21-MINI is a standardized acoustic noise-reduction hardware module from Bothlent for AI robots, smart cockpits, ATMs, hospital queue terminals, and other AIoT devices. It combines environmental noise removal, echo cancellation, VoIP call noise reduction, microphone-array wake-up, sound-source localization, and super-directional pickup with voice-separation and sound-classification algorithms. Beyond speech processing, it distinguishes natural sounds such as thunder, birds, and animals from specific human sounds such as snoring and coughing, making it suitable for noise-pollution control, smart security, and home health-monitoring devices. The vendor page does not disclose the microphone-array count, pickup range, interface, or electrical specifications.
