Silicon Sensing Upgrades Gyro for Downhole Surveying
the unit’s mass by 40% and allows it to be installed far more easily in space-limited applications, such as the 25mm diameter cylinders typically used in downhole drilling equipment.CRS39A also incorporates upgraded micro electro-mechanical systems (MEMS) and electronics, including new drive electronics and improvements to the sensor head. These have delivered significant performance enhancements in critical areas such as bias instability, angle random walk, noise and vibration tolerance whilst multiple on-board temperature sensors allow CRS39A performance to be tuned to suit each operating
Deep-sea LED Strobe Uses High-potential Driver
use o AUVs such as the Remus 100, 600 and 6000, Dragonfish LED strobe lights offer compact size, high brightness (30,000 lumens at 5ms, 42,000 lumens at 200µs) and low current draw (550 mA at 24Vdc), suited for AUV-based still photography, where payload size and power budget are critical. Drive electronics, thermal protection and intelligent microprocessor control are integral in the Dragonfish’s small 1ATM, 6,000m-rated, anodized aluminum housing. External power and trigger are all that are needed to operate. The unit is easily synced to a standard TTL camera shutter, and will self-quench
Dr. Harold Robinson Named Top Scientist of the Year
tested a compact, low-frequency transducer for tracking ranges, which will enable small-diameter vehicles to be used at a wider variety of naval at-sea test facilities. These range transducers can also replace three current tracking transducers with a single drop-in replacement without changing the drive electronics. One of his designs holds the world record in acoustic power/volume and acoustic power/weight metrics used by sonar transducer designers. Robinson holds bachelor of science, masters of science and doctorate degrees in physics from the University of Connecticut. He will receive
