71 Sightline Applications’ new 1750-OEM The DA 14-N servo actuator from Volz SightLine Applications announced updates aimed at expanding the use of its onboard video processing technologies. The first was its new 1750-OEM, which represents the next generation of its 1500 single-channel processor for advanced surveillance functionality and AI classification via small cameras. “The 1750-OEM records 1080p30 video with H.265 encoding, whereas the 1500 just supports video quality up to 720p30 and encoding to H.264,” explained Danny Guerrero. “It weighs 23 g and measures 33.3 x 45 mm, so as a low-SWaP system it’s meant for customers of the 1500 who want a similar footprint but with greater processing power and throughput, and probably those who just want one or two tailored pieces of our AI IP, such as tracking moving targets or some discrete object recognition.” The company also showed its 4000OEM, which supports three digital video inputs of up to 4k30, as well as around 100 different camera models, and comes with H.265 encoding. SightLine said the next generation of the 4000 is expected at the end of the year, and will result in additional, more powerful versions of what is at present the company’s most powerful solution. The 1500 and 3000 processor boards meanwhile are still being supported for customers who use them, and will continue to be for the foreseeable future. Lastly, SightLine announced that its full software suite can now be used on thirdparty ARM computing systems. “Initially, our algorithms could only provide analysis functions on boards other than our own hardware products, like object detection, tracking, AI classification and provision of telemetry data,” Guerrero said. “But with our new3.6.2 software release, we can now perform rendering functions, including encoding, enhancement, and KLV data on Nvidia Jetson hardware, for customers who want to continue using their current hardware.” Volz has launched a new servo, the DA 14-N, aimed at filling the niche between its own high-end servos for professional vehicle OEMs and lower-end servos for hobby-grade aircraft or new entrants into the uncrewed industry. “We’ve had a product called the DA 15-N for several years now, which is used on the AAI Aerosonde, Insitu ScanEagle, and Zipline’s Zip, be it through PWM, CAN, or RS-485 command interfaces,” said Mark Juhrig. “It has features such as a BLDC motor, brushless position sensor and an allsteel geartrain, with most customers flying it for a total of 2500 hours. “We took those features and the associated components, and fitted them in a smaller case to make the DA 14-N. It’s a different concept to our other servos in that it’ll be a COTS product, with no customisability in terms of housings, and interfaces and so on. But it’ll have an MTBR of over 500 hours, a rating to IP64 for moisture ingress protection, and most important it’ll be a drop-in replacement for small hobby servos, but with a lifespan many times longer.” Now in production, Volz anticipates the DA 14-N to be particularly attractive to lower-end uncrewed systems manufacturers and integrators who want a higher level of performance and costefficient long-termmaintenance. It will therefore be available solely with a PWMinterface and 5-9 V operating voltage, as this is the most common type of interface for lower-end systems. “It’ll be much closer to a hobby servo in price terms than any of our previous product lines –less than half the price of a DA 15-N – and because it’s COTS, customers will be able to receive it 2 weeks after ordering it,” Juhrig added. Taisync has released its Viulinx DUO, a new dual-band radio module for video, telemetry and RC data, which operates at 2.4 GHz and 5.8 GHz. The system can be configured for bandwidths of 10 or 20 MHz, as well Xponential 2023 | Show report Uncrewed Systems Technology | June/July 2023
