This paper demonstrates a two-layer SU8 photoresist micromachining technology that has similar performance to conventionally machined metal. The technology is demonstrated in the WR-3 band (220-325 GHz). Three different WR-3 band circuits, namely a WR-3 band straight through waveguide, a bandpass filter and a dual-band filter are demonstrated. For the measurements, a conventionally precision machined metal block was used for the WR-3 band waveguide and the bandpass filter to achieve good calibration and accurate interconnection with standard waveguide flanges; whereas, for the dual-band filter, two back-to-back right-angle bends are added in order to achieve accurate, reliable waveguide interconnection without using the metal block. A measured average insertion loss of 0.03 dB/mm has been achieved for the 14.97 mm long straight through waveguide. This is comparable to the loss of around 0.02 dB/mm for a standard metal waveguide at this frequency. The fifth-order waveguide filter exhibits an 8% 3 dB bandwidth at a central frequency of around 300 GHz. The minimum passband insertion loss was measured to be around 1 dB and the return loss was better than 10 dB throughout the passband. The filter results showed a notable improvement over those obtained from the separate SU8 layer technique that was also used to make the same devices for comparison. To further demonstrate the advantages of the new two-layer SU8 micromachining technique, the dual-band filter included isolated regions in the waveguide channels that would have not been possible for micromachining using the previous separate single layer technique. The performance of the micromachined dual band filter was excellent in terms of very low insertion losses on both passbands. © 2011-2012 IEEE.

Autoimmunity Reviews | Year: 2011

Inconsistencies in ANCA (anti-neutrophil cytoplasm autoantibodies) and other NSA (neutrophil-specific autoantibodies) terminology frequently cause incorrect indications, choices, applications and interpretations of ANCA diagnostics in routine practice, except for ANCA-associated vasculitis. A review of the current knowledge and the authors' personal experiences based on routine assessments of ANCA and other NSA are documented and presented. A better understanding of the principles and mechanisms of ANCA and other NSA responses and determination, as well as unification of their terminology could result in improvements in indications, applications and the interpretation of ANCA diagnostics in diseases other than vasculitis, especially in IBD (inflammatory bowel diseases), AILD (autoimmune liver diseases), CTD (connective tissue diseases) and other chronic neutrophil-mediated inflammatory diseases. © 2010 Elsevier B.V.

Patent
Dynex | Date: 2011-07-14

An automated immunoassay apparatus is disclosed comprising a single optical reading device for reading two microtitre plates. A first microtitre plate is loaded into an upper plate holder which is linearly translated at a fixed height. A second microtitre plate is loaded into a lower plate holder. The lower plate, holder runs along a contoured track which varies the vertical height of the second microtitre plate.
