Latest Patents

One of Benson's latest patents is for a heat pipe with improved wick structures. This invention features an enhanced planar heat pipe wick structure that incorporates projections formed through micromachining processes. These projections create arrays of interlocking, semi-closed structures with multiple flow paths on the substrate. Additionally, the projections include overhanging caps at their tops, which enhance the capillary pumping action of the wick structure. The capped projections can be formed in stacked layers, and a layer of smaller, closely spaced projections without caps can also be integrated on the substrate between the capped projections. Inexpensive materials such as Kovar can be utilized as substrates, with the projections formed by electrodepositing nickel through photoresist masks.

Another significant patent by Benson is a tungsten bridge designed for the low energy ignition of explosive and energetic materials. This device is fabricated on a silicon-on-sapphire substrate, featuring an insulating bridge element defined using standard integrated circuit fabrication techniques. A thin layer of tungsten is selectively deposited on the silicon bridge layer through chemical vapor deposition techniques. Conductive lands are then deposited on each end of the tungsten bridge layer to complete the device. This innovative design has been found to exhibit substantially shorter ignition times compared to standard metal bridges and foil igniting devices, requiring significantly less energy for ignition.
