Val Patterson, 59, an electronic engineer from Salt Lake City, died of throat cancer July 10. He wrote his own obituary last fall, using the piece to confess to some actions he made in life: stealing a safe and not earning his Ph.D. The obituary was published in the Salt Lake Tribune. Patterson calls himself "a true scientist," and describes his upbringing and … [Read more...]
Heat Sink Extrusions Meet Space Constraints of LED Light Engines
Ohmite Wakefield Solutions’ 19000 Series of radial-fin heat sink extrusions for LED light engines helps meet space constraints and operating parameters. The heat sink extrusions are black anodized for maximum thermal performance, and their radial-fin design has been optimized for natural convection. OHMITE intends for its product to make matching the right heat sink to the … [Read more...]
CPU Cooler Fan for Maximum Cooling Performance
LEPA introduces its Vortex fan, which uses fluid mechanics to generate a powerful air twirl that concentrates cool air on the hot spots inside a system. At full speed, the Vortex fan achieves a static pressure of 2.18mm-H2O while maintaining a low noise level. That way, it is also an ideal solution for CPU coolers or radiators. LEPA equipped the fan with a PWM speed control, so … [Read more...]
Safety Standards for Higher Level Lighting Products
IEC/TR 62778:2012 provides clarification and guidance for the assessment of blue light hazard of all lighting products that have the main emission in the visible spectrum (380 nm to 780 nm). By optical and spectral calculations, it is shown what the photobiological safety measurements relate about the product and, if this product is intended to be a component in a higher level … [Read more...]
Quantum Computing Uses Diamonds to Eliminate Cooling Needs
A group of Harvard scientists were able to create quantum bits, or qubits, and store information in them for nearly two seconds – all at room temperature. Previous work with qubits required they be cooled to near absolute zero, but the Harvard scientists used diamonds that increased the life span of previous systems by six times. This research is an important step in research … [Read more...]
