Multiple-Input DC Converter Distributes Power from Battery

The Direct Electric Power Converter (D-EPC), a semiconductor switching circuit, controls power distribution among multiple DC power sources without using a DC-DC converter. During every pulse-width-modulation (PWM) cycle, the DEPC alternately activates one of the multiple inverter circuits, which are connected to the power sources. The converter has been proven experimentally to conduct charging operations and distribute power between two DC power sources having different voltages.

Piezo Technology Offers Precise Actuation, Generates Less Heat

“VIVA” piezo technology enables a valve to be direct-operated. The piezo element is protected from the fluid stream to eliminate potential for clogging or contamination failure. The valve is directly shifted by the VIVA arm, and requires only a standard 40-micron air filter upstream. No minimum air pressure is needed for operation.

Conductive Polymers Integrate Antennas Into an Electronic Device Housing

Micron-sized conductive fibers within a thermoplastic matrix enable polymeric antennas that can be molded in various shapes and sizes. The polymer antenna technology can even become an integral part of a device housing, thus reducing part count, concealing itself, and simplifying the manufacturing process. With adhesion, the lead is attached to the antenna’s central receptor patch.

Long-Wave IR Sensors Enable Remote Temperature Measurement

A 2000-pixel long-wave infrared sensor detects and monitors hot spots, wear points, and friction on operating machinery and other equipment. Using software, the device also displays the condition of heat-generating tools, including motors and bearings; collects temperature readings from running machines, lab equipment, and experiments; monitors objects being oven-cured or heat-sealed; and signals an alert when specific temperature conditions are met. The device also features an IP65/NEMA4 enclosure.

Lightweight Building System Eases Construction

A silicate-based, lightweight construction system features building blocks that are already covered by insulating material. After the concreting process, the formed, reinforced concrete tissue grid becomes load-bearing. There is no need for applying any subsequent heat or sound insulation.

Plastic Production System Controls Directional Forces and Tearing

To achieve exacting performance requirements, “Smittie” technology produces predictable bi-axial or mono-axial orientation in polymer materials. The system eliminates expensive equipment, curbs energy use, reduces the need for highly skilled labor, and shortens setup times.

Small-Droplet, Emissions-Control Nozzle Ensures Consistency

Macrospray® nozzles produce highly uniform spray patterns and droplet sizes (in the size range of 10-30μm Sauter Mean Diameter/SMD). The nozzles are created from digital tools with the flow features chemically etched into bonded substrates, resulting in a monolithic structure. Hydraulically smooth internal surfaces reduce flow losses. Nozzle passages, metering slots, spin chambers, and exit orifices are designed to minimize pressure drops.

Steel Alternative Features Higher Usability Strength

A new material offers a lighter weight and at least 30% higher usability strength compared to traditional steel. The equipment necessary for the production of the new technology is identical to equipment used for the manufacturing of conventional steel. It does not require other machinery, and the steel can be cast in molds as well as in closed continuous casting machines.

Polymer Indicator Monitors Spoilage

The Fresh Stripe multi-layer indicator for meats is manufactured or incorporated into packaging using conventional roll-to-roll processes. The polymer layer biodegrades at a predictable rate in the presence of the same hydrolytic bacterial enzymes that degrade meat. As the indicator degrades, it changes appearance so that a consumer can effectively judge the meat’s freshness. Freezing, refrigeration, and heat do not degrade the performance of the indicator or affect its accuracy.

Holographic Technology Offers Robust Authentication

A new security technology provides a hologram invisible to the naked eye. The tool requires viewing with a prism to discover the holographic image. The product also supplies a primary and complementary hologram for applications where visibility is required or desired. Both approaches offer robust authentication and are extremely difficult to counterfeit. The technology is suitable for high-volume production.
