Silicon Sensing’s Sales Rise 65% as it Hits 25th Anniversary
.“Our products are at the heart of many attitude and heading reference systems (AHRS) that are being used to map the seabed and to monitor the location of surface vessels,” said David Sommerville, General Manager, Silicon Sensing Systems.Silicon Sensing’s patented, micro electro-mechanical systems (MEMS) technology spans a range of inertial requirements, from single, silicon vibrating ring sensors to full 6 axis inertial measurement units (IMU’s).The latest inertial measurement unit, the DMU41, redefines the capabilities of MEMS technology, bringing high-performance sensing in

, expanding payloads, enhancing testing and quality control processes and optimizing new technologies for production, VideoRay said.Holtz served in the U.S. Navy as a Machinery Repairman Second Class (E-5). During that time, he supervised lathe and computer numerical control departments and repaired mechanical systems to support the Navy’s surface and subsurface fleet.Since his service with the Navy, Holtz has gone on to hold design engineering, product development, production processing, intervention engineering and managerial positions with a focus on underwater robotic systems, subsea technical

design of the company’s latest generation, tactical grade inertial measurement unit (IMU) - the DMU41.“These are remarkable times in inertial sensing with a long held technological status quo now rapidly shifting," said Dr. Marshall. "A number of recent micro-electro-mechanical systems (MEMS) inertial product launches are truly challenging fiber-optic gyro (FOG) performance for the first time – with products that are much more compact and rugged - and less power consuming. One of these market disrupting products is our DMU41 9 degrees of freedom (DoF) IMU.”Before

includes a move to a single board from two. This has reduced 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

aggressive mode of attack?Over the last 10 years, the integration of operational technology (OT) and information technology (IT) systems in the maritime environment has accelerated dramatically. Onboard ships, modern network technologies allow for greater control and monitoring of engineering and mechanical systems, leading to increased reliability and efficiency for vessel operators. For ports and other infrastructure hubs, many key industrial systems now have physical connectivity with the outside world through integration with internal IT-based control systems. Autonomous cranes and driverless flatbed

depend on the circumstances. They may either be able to wait for rescue or, if the circumstances require it, to evacuate via an emergency escape system. The SET is a diving bell equipped with a replica submarine escape tower. This escape training module is moved vertically in a water column using mechanical systems which allows comprehensive training to be carried out in a perfectly controlled environment. Through this new partnership, JFD will be able to offer the SET solution, or variants, to customers thereby broadening its escape offering. JFD can also tailor its provisions to customers’ unique

or unmanned surface vessels) and just another tool. Back then, the idea of using a robot boat to do hydrographic survey and map the sea floor was hard, if not impossible. Now you can hire a boat ready to do that.”Since 2002, the evolution of sensors; GPS, heading sensors, micro-electronic mechanical systems (MEMS), helping vessels to understand where they are, has been important, says Manley, as well as the development of payload sensors. “We have had multibeam sonar for a long time, but it was expensive, complex, very large and typically built into the hull of a ship. Those instrumentation
