Hermetic Seal Leak Detection Apparatus with Variable Size Test Chamber

A streamlined, cost-effective, sensitive approach to detecting leaks in hermetic seals. Marshall Space Flight Center, Alabama NASA’s Marshall Space Flight Center has developed a unique apparatus ideal for use in nondestructive testing (NDT) of hermetic seals of containers or instrumentation. The device is capable of detecting both large and small leaks and can be calibrated to characterize the relative leak rate. Its simple design does not require specialized gases for pressurization and detection, and eliminates the need for expensive instrumentation such as a mass spectrometer to analyze leaks and achieve high sensitivity. Low in cost and simple to manufacture, the patent-pending technology is ideal for use in many industries, from aerospace applications to food packaging and commercial goods.

Coming Soon - Thermal Management: Heat Pipes, HiKTM Plates, and Vapor Chambers – Selection and Modeling

Heat pipes, high conductivity (HiK™) plates, and vapor chambers are two phase technologies that are often considered for electronics cooling.  All three devices rely on the very high evaporation and condensation coefficients of two phase fluids to reduce the ΔT between the source and the sink for a given power.  When properly engineered for power and mission duration, all of these devices provide passive, reliable cooling.

Boosting Machine Vision with Built-in FPGA Image Preprocessing

Since imaging processing tasks can consume major CPU resources in machine vision applications, increasing processing performance within size constraints is, accordingly, a common challenge for solution providers. The following discusses the efficacy of FPGA in addressing such performance shortcomings, presents the image processing tasks most suitable for FPGA, and compares the capabilities of CPU and FPGA in operation. A built -in FPGA image preprocessing solution supporting machine vision app lications is then presented.
