TI unveils ULC1001 ultrasonic lens cleaning chip for self-cleaning cameras

TI ULC1001 self cleaning camera

Texas Instruments (TI) has introduced the ULC1001 digital signal processor (DSP) ultrasonic lens cleaning (ULC) technology designed – when combined with DRV2901 piezo transducer driver – for self-cleaning camera systems to quickly detect and remove dirt, ice, and water using microscopic vibrations. Cameras used in the automotive, industrial, robotics, and smart farming industries may require cleaning from time to time and that usually means manual cleaning leading to potential downtime, higher maintenance cost, and so on. It could also be done through mechanical parts but that adds further complexity to the system, so instead, Texas Instruments ULC1001 and DRV2901 combo enables cameras to rapidly self-clear contaminants using vibrations to eliminate debris. The datasheet describes the ULC1001 as a “Configurable Ultrasonic PWM Modulator With I/V Sense Amplifiers” with the following specifications: Integrated Programmable Cleaning Modes Water (expelling) Deice (melting and expelling) Mud (dehydrating and expelling) Auto-Cleaning (detecting and expelling) Custom Cleaning […]

ROCK Base triple-frequency RTK/GNSS base station works with Web3 GEODNET decentralized network

ROCK Base RTK network base station

ROCK Robotic has announced the ROCK Base triple-band multi-constellation RTK/GNSS base station that works with the Web3 GEODNET decentralized GNSS reference network, with the solution designed to offer centimeter accuracy to support applications such as civil surveying, high-definition mapping, digital twin creation, and robotic solutions. Real-time Kinematic (RTK) is a relative positioning technique relying on GNSS (GPS,  Galileo, GLONASS, Beidou …) and allowing centimeter positioning accuracy. The technique requires an RTK “Base station” like the ROCK Base and a lower-cost “Rover station” typically attached to a vehicle or drone. For higher accuracy, it’s also possible to use a Network RTK: Network RTK is based on the use of several widely spaced permanent stations. Data from reference stations is combined in a common data processing in a control center. The control center computes corrections for the spatially correlated errors within the network. These corrections are transmitted to the rover. Comparing to […]

MistySoM Renesas RZ/G2L or RZ/V2L SoM and devkit goes for $112 and up

MistySOM devkit Renesas RZ/G2L or RZ/V2L

We’ve previously written about several system-on-modules and SBCs based on Renesas RZ/G2L or RZ/V2L Cortex-A55/M33 processors such as Geniatech “AHAURA” RS-G2L100 and “AKITIO” RS-V2L100 single board computers, Forlinx FET-G2LD-C system-on-module, and SolidRun RZ/G2LC SOM and devkit. But most of those are hard to buy, and you need to contact the company, discuss your project, etc… before purchase, except for the SolidRun Renesas RZ/G2LC Evaluation Kit going for $249. Another option is the MistyWest MistySOM module offered for $112 and up on GroupGets with either Renesas RZ/G2L or RZ/V2L processor, as well as an optional carrier board.

Wi-SUN: An LPWAN standard for Smart Cities, Smart Agriculture, large scale IoT deployments

Wi SUN network architecture

Wi-SUN is a standard (IEEE 802.15.4g) managed by the Wi-SUN Alliance and designed for Smart Cities, Smart Agriculture, and other large scale IoT deployments with a large number of devices thanks to the use of IPv6 mesh networking. The organization was founded in 2011 to “support the worldwide development of Wireless Communications Networks for Utilities, Smart Cities and IoT”, but due to the niche nature of target applications, it does not get that much press coverage and was only recently brought to my attention. Wi-SUN stands for “Wireless Smart Utility Networks”or “Wireless Smart Ubiquitous Networks”, and the standard aims to connect streetlights, cameras, weather stations, smart metering, utility transmission systems, and others to enable data-sharing between city services to improve their efficiency, save costs, and offer improves services to citizens. Wi-SUN FAN (Field Area Network) is the latest protocol managed by the Wi-SUN Alliance with over 95 million units shipped […]
