AUVSI Xponential 2019 | Show report integrated electronics and gearboxes, for applications in the unmanned and electric VTOL markets. “Our Model 220 Rotary servo actuator will deliver between 50 and 100 lb-in of torque, while our Model 863 Rotary servo actuator will provide 150 lb-in,” said Richard O’Donnell. “Meanwhile, our Model 863 is IP67- rated and completely sealed using a connector seal, a shaft seal and another gasket to seal between the gearbox and the electronics,” he said. “It is often recovered from water, as it is widely used on target drones and UAVs, and can withstand depths of 3 m for 48 hours without damage or water ingress.” The gaskets typically use Teflon or similar materials to seal the connector and the output shaft. The Model 220 weighs about 270 g and measures 10.4 x 7.4 x 2.3 cm, while the 863 weighs about 910 g while measuring 11.3 x 10.4 x 4 cm. Delta Digital Video showcased its new, small-form-factor H.265 video encoder, the Model 7805R. “It’s our smallest video encoder using the new H.265 compression algorithm. It measures about 97 x 92 x 30 mm, while weighing 227 g,” said George Nelson. “The size challenge comes from H.265 being computationally intensive, so you need more processing power, which translates into more heat generation. That typically results in the need for a bigger fan to get the heat out of the box, or some form of conduction cooling.” As well as being SWaP-optimised for UAS integration, the 7805R is designed to be a drop-in replacement for its H.264- compliant predecessor, the 6805R. The 7805R consumes 10 W in normal operation, and can output video at resolutions of 1080p29/30, 720p59/60, 1080i59/60, 480i29/30 and 576i25. The encoder has a rated latency of about 50 ms and can operate at altitudes of up to 35,000 ft. Delta Digital Video’s 7805R
