Metal Bellows for Sensors and Instrumentation Servometer ® miniature bellows can be added to instrumentation and manifolds of almost any shape or size. Barometric and differential pressure, gauge, and temperature can all be compensated for using bellows technology. Electrodeposited bellows have been used to increase the accuracy inside capacitive and potentiometric pressure sensors to increase linearity. You can request a free sample too (top right of website).

Army converts heat to electricity at record high rates, breakthrough research shows U.S. Army-funded research at the University of Michigan has resulted in demonstrating a new approach for more effectively converting heat into electricity -- an approach traditionally referred to as thermophotovoltaics -- which is useful to Soldiers because it can generate power from any heat source and can be configured to work day or night.

Low-cost LiDAR comes to mass vehicle production Chinese manufacturer RoboSense says that its new, high-performance solid-state LiDAR system for autonomous driving is 1/400th the price of traditional 64-line LiDAR systems and has updated features not found in even higher priced systems. The $200 RS-IPLS Intelligent Perception LiDAR system (yup, the price really is two Benjamins) is designed for the mass production of vehicles. On price, that's a huge fall from the first under-$10,000 systems rolled out in just the last two years.

Powerful $100 ultrasound machine right around the corner Engineers at the University of British Columbia have developed a new ultrasound transducer, or probe, that could dramatically lower the cost of ultrasound scanners to as little as $100. Their patent-pending innovation -- no bigger than a Band-Aid -- is portable, wearable, and can be powered by a smartphone.

'Wearable cockpit' concept for pilots becoming a reality BAE Systems is working on a novel way for pilots to fly fighter jets. Researchers and engineers at the U.K.-based military and defense company are developing technologies to enable pilots to control the fighter jet of the future with the blink of an eye, creating a software-only cockpit that's upgradable, adaptable, and reconfigurable -- and it's planned for 2025.

Top Tech Tips: Programmable linear position sensors Novotechnik's LS1 Series of sensors gives engineers the capability to adjust for a mechanical offset without moving the sensor, optimize noise rejection and accuracy for their application, as well as eliminate the need for a programmable process monitor. Applications include material handling equipment, crimping machines, and position sensors for linear actuators. Learn more. A detailed white paper is available (no registration required).

Get your CAD under control before implementing PLM Despite the widespread adoption of PDM and PLM technology by large companies, the vast majority of companies below 20 designers have yet to implement these solutions and still just use shared drives to store their CAD files. Each year that passes without PDM/PLM is another year of CAD data becoming more disorganized, which makes it even more difficult to migrate to a new system. But some companies are turning to CAD geometry indexing and search technologies to better aggregate their existing CAD file shares. By Jon Gable, Adaptive Corporation

Engineer's Toolbox: Best practices for integrating electromechanical engineering into industrial automation systems Jim Mangan from Nook Industries explains how to integrate electromechanical tech into existing and newly designed automated industrial systems successfully. He addresses the advantages these systems have over air and hydraulic systems, the change in mindset and processes that must happen to create ideal electromechanical systems, the reasons for integrating electrical and mechanical systems, benefits, and common mistakes to avoid.

Conserve precious liquids with patented no-drip atomizing nozzles EXAIR's new 1/8 NPT No Drip External Mix Atomizing Spray Nozzles mix liquid and air outside the nozzle and allow the air and liquid flows to be adjusted independently. The new, patented No Drip External Mix Atomizing Spray Nozzles work in the same way the company's standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. Post-spray drips waste precious resources such as expensive coatings, chemicals, or water.

Webinar: Are you afraid to share mission-critical spreadsheets? Is spreadsheet chaos hurting your supply chain planning and asset management process? Loved for its flexibility, agility, and power, Excel is a go-to tool for many supply chain applications. However, frustration and inefficiency often arise from Excel's well-known weaknesses such as version control issues, exposed IP, and error introduction. Learn how to transform critical spreadsheets into secure enterprise-grade web apps in this informative one-hour webinar from EASA Software. Two times available on Sept. 27: 9 am and 2 pm EDT. Learn how EASA deploys Excel at the enterprise level (video very helpful).

Traction drives leverage engineered fluids Rolling Motion Industries (RMI) has released two high-efficiency traction drives: the MAR-17-1-2.1 (speeds to 3,600 rpm with 10 to 20 in./lb of torque) and MAR-23-1-2.1 (3,600 rpm with 20 to 30 in./lb of torque). These one-way traction drives have only six moving parts and use an engineered traction fluid with a coefficient of friction of just 0.1 to 0.12. These traction drives typically last three times longer than conventional gearboxes, and with no metal-to-metal contact they generate up to 72 percent less heat after 24 hr of continuous operation. Additionally, they create up to 38 percent lower dB at 3,000 rpm than conventional gearboxes (less than a home refrigerator). Applications include: pumps, blowers, fans, turbo and superchargers, conveyers, HVAC systems, and medical -- anything that rotates.

DARPA/Boeing Experimental Spaceplane program successfully completes engine test series DARPA's Experimental Spaceplane (XSP) advances toward its goal for rapid turnaround and on-demand launch with the completion of a rigorous engine test series. With partner Boeing, the program envisions a fully reusable unmanned vehicle, roughly the size of a business jet, that would take off vertically like a rocket and fly to hypersonic speeds.

| How to measure the free height of a Smalley crest-to-crest wave spring | |
Engineers often ask Smalley engineers, "How do I measure the free height of a wave spring?" Knowing how to properly measure a wave spring at its free height can save valuable inspection time. It is also important to know that the free height of a wave spring is typically a reference dimension, because Wave Springs are ordinarily designed to provide a specific load at a work height. The work height is the dimension we tolerance on, Smalley says. Learn how to measure free height.
