A2 Technologies Have Entered Into A Patent License Agreement With The Boeing Company To Utilize The Patents In The Application Of A2’s Portable Exoscan FTIR Spectrometer

A2 Technologies today announced they have entered into a patent license with the Boeing Company allowing the use of Boeing patents in association with the development, manufacture and sale ofA2 Technologies’ FTIR Spectrometers. The license will permit A2 Technologiesto utilize the patents in the application of A2’s portable Exoscan FTIR spectrometer for non destructive testing of aerospace composite and metal materials. Examples of the applications include the use of the Exoscan for measuring the affect of excessive heat on the chemical structure and strength of composite material, and the ability to non-destructively analyze the effectiveness of certain surface treatments in composite and metal materials.

Exoscan is a high performance FTIR that puts a laboratory quality spectrometer, literally in the palm of one’s hand. With the addition of the Boeing patent licenses, A2 Technologies can now provide proven FTIR based analytical methods that will significantly increase the types of materials that can be analyzed in a variety of applications that are critical to aircraft manufacturing and maintenance.

Jon Frattaroli, CEO of A2 Technologies stated “we are excited to have entered into this licensing agreement with the Boeing Corporation. Boeing is clearly the leading US aircraft manufacturing company. They are also leaders in using FTIR spectroscopy in a wide range of aerospace applications, particularly related to composites and surface analysis. But it is the combination of A2’s Exoscan spectrometer and the Boeing patents that will finally enable methods traditionally carried out in laboratories to be deployed into aerospace manufacturing facilities and maintenance hangers.”

Headquartered in Danbury, Connecticut, A2 Technologies is taking FT-IR spectroscopy out of the lab and into the field. A2 Technologies manufacture and develops portable FT-IR spectrometers designed for the analysis requirements of the aerospace, petrochemical, environmental, metals and mining and other industries where there is a need for at-site, out-of-laboratory analysis.

Qspeed Semiconductor is introducing its Q-Series family of low Qrr, high softness factor, boost converter rectifier diodes

Qspeed Semiconductor, a designer and manufacturer of innovative, energy-saving power semiconductor devices, today introduced its Q-Series rectifier family. The new family of devices was designed specifically for use in power factor correction (PFC) circuits that deliver from 200 to 1000 W of power. Replacing anultrafast diode with a Q-Series device typically realizes efficiency improvements of 0.5 to 1.5% in the boost converter stage, which are similar to those obtained by using exotic Silicon Carbide diodes. Developed using Qspeed’s proprietary technology, the Q-Series family of devices has the lowest reverse-recovery-charge (QRR) and the best softness factor of any high-speed silicon rectifiers currently available on the market.

“Power supply designers no longer have to work around inferior diodes or use expensive Silicon Carbide devices,” said Michael T. Robinson, CEO of Qspeed Semiconductor. “Our Q-Series rectifiers make it easy to improve the efficiency of PFC boost converters and lower MOSFET operating temperatures while minimizing EMI generation, all without the use of snubbers and clamps.”

The Q-Series product family consists of three devices, which are rated to deliver continuous forward current values of 3, 5 and 8 A respectively. The 3 A device (LQA03TC600) would typically be used in boost converter stages that deliver from 200 to 400 W of continuous output power. The 5 A device (LQA05TC600) would find its home in converters that deliver from 400 to 700 W, while the zone for the 8 A device (LQA08TC600) is from about 700 to 1000 W.

“Until now, engineers looking to improve the operating efficiency of their AC-DC power supplies had to resort to using costly, Silicon Carbide diodes,” said Richard Francis, Qspeed’s Chief Technology Officer. “With the lowest reverse recovery charge and the best turn-off softness factor of any commercially available silicon rectifier, the Q-Series parts are being adopted faster than any new power semiconductor I have ever seen.”

Pricing and Availability:
All three members of the Q-series family are currently available in high-volume production quantities. The 3 A LQA03TC600 sells for 78 cents each, in fifty-thousand-piece quantities. The 5 A LQA05TC600 is going for 88 cents each, in 50,000 piece lots. The 8 A LQA08TC600 is selling for only 1.08 U.S. dollars each, in 50 k piece orders.

About Qspeed Semiconductor:
Qspeed Semiconductor designs, manufactures and sells innovative, highly-efficient, energy-saving, power semiconductor devices. Presently, the company is focused on the active components currently used in offline power conversion equipment. Headquartered in Santa Clara, California, the company has manufacturing, testing, sales and logistics facilities located in Japan, Taiwan and Manila.
