Why a Circuit Breaker and a Diode Are No Longer Enough in Military Vehicle Power Systems

If your 28VDC system relies on a circuit breaker, a diode, and a TVS for protection, it may be prepared for yesterday’s threats—but not necessarily today’s.

Modern military electronics are exposed to reverse battery events, brownouts, ripple, EMI, and thousands of transient disturbances that never appear in qualification reports. This article explores why traditional protection schemes are no longer enough and why more engineers are moving toward Electronic Power Protection architectures.

Why Most Engineers Use Bevel Gears for Only 10% of What They Can Actually Do

Most engineers think of bevel gears as a simple way to transfer motion at 90°. In reality, bevel gears represent an entire family of solutions including miter gears, angular bevel gears, hypoid gears, precision motion systems, and high-torque drive technologies. This article explores ten applications that many designers overlook and explains how the right bevel gear selection can simplify mechanical systems, improve efficiency, reduce noise, and eliminate unnecessary components.

You Sealed the Lid. Did You Forget the Screws?

Most engineers focus on enclosure gaskets when designing for IP67 or IP68 protection, yet every screw passing through the enclosure wall can become a potential leak path. This article explains why sealing fasteners matter, explores the real role of Black Oxide finishes, and examines how Seelskrew® fasteners help eliminate one of the most overlooked weaknesses in sealed enclosure design.

2000Hz IMU? Before You Get Impressed, Understand Three Completely Different Numbers

When evaluating an IMU, many engineers focus on a single specification: update rate. A 2000Hz IMU must be better than a 200Hz IMU – right? Not necessarily. In real stabilization, tracking, and navigation systems, performance depends on much more than output frequency alone. This article explains the critical differences between Bandwidth, Output Rate, and Baud Rate, and shows why an IMU that sends data faster is not always the one that delivers better system performance. Through practical examples from EO/IR gimbals and UAVs, we explore how understanding these three parameters can prevent costly design mistakes and lead to more effective sensor selection.

Why a Million-Dollar Medical System Still Uses Rack & Pinion

Most medical device engineers start by asking how accurate a motion system is. The more experienced ones ask a different question: how accurate will it still be after millions of motion cycles? That shift in thinking helps explain why Rack & Pinion remains a serious contender in some of the world’s most advanced medical systems.

How Differential Pressure (ΔP) Can Reveal Problems Long Before a System Shuts Down

,

Most systems do not fail suddenly. Filters clog gradually, pumps lose efficiency over time, and vacuum systems drift out of specification long before a fault alarm appears. In many cases, the earliest warning sign is not temperature, vibration, or power consumption – it is a subtle change in differential pressure (ΔP). This article explains why Differential Pressure is one of the most valuable indicators of developing failures, how Pressure Switches, Vacuum Switches, and Differential Pressure Switches are used for early fault detection, and why the most important parameter in your system may not be pressure itself, but the small change that appears long before the failure becomes visible.

The IMU Was Excellent. The Image Still Shook.

Two MEMS IMUs with remarkably similar datasheet specifications were evaluated for a high-performance stabilization system. Both offered excellent bias stability, low noise, and impressive inertial performance. Yet one delivered noticeably better tracking, faster settling, and superior image stability. What caused the difference? This case study explores why latency, synchronization, bandwidth, and timing determinism often matter more than traditional navigation specifications when designing EO/IR, gimbal, antenna tracking, and UAV stabilization systems.

Why MIL-PRF-39019 Circuit Breakers Still Appear in New Defense Programs

MIL-PRF-39019 qualified hydraulic-magnetic circuit breakers continue to play a critical role in modern defense systems, from armored vehicles and main battle tanks to EO/IR payloads, radar platforms, and tactical communication shelters. This article explores why engineers still specify Airpax AP Series circuit breakers, how they fit into 28VDC military power architectures, and why part numbers such as M39019/02-231, M39019/02-255, M39019/01-249, and M39019/06-219S remain relevant in new programs, modernization efforts, and long-life military platforms worldwide.

Medical Footswitches for IEC / UL 60601-1 Systems – Safety, Reliability and Design Considerations Every Engineer Should Know

Medical Footswitches are far more than simple ON/OFF controls. In IEC / UL 60601-1 medical systems, they influence safety, risk management, usability, reliability and regulatory compliance. This comprehensive guide explains Footswitch architectures, Human Factors considerations, reliability requirements, ingress protection ratings, OEM customization options and the critical questions every medical device engineer should ask before selecting a Footswitch.
