20110199107 | METHOD AND APPARATUS FOR CALIBRATING A TEST SYSTEM FOR MEASURING A DEVICE UNDER TEST - Methods and apparatus for calibrating a vector network analyzer (VNA) and characterizing a device under test. In one example, a device fixture including a pair of embedded device adapters provides an interface between a device under test (DUT) with non-coaxial connectors and the coaxial connectors of the VNA, and moves the calibration reference plane from the coaxial connectors of the VNA to a DUT reference plane at the leads/connectors of the DUT. A through fixture having a pair of similar through adapters is used to establish the DUT reference plane and to facilitate characterizing the device adapters such that they can be de-embedded from measurements of the device fixture. | 08-18-2011 |
20120109566 | METHOD AND APPARATUS FOR CALIBRATING A TEST SYSTEM FOR MEASURING A DEVICE UNDER TEST - A calibration method for a two-port VNA includes presenting a high reflection calibration standard and measuring reflection data for each of the two ports, calculating a location of the high reflection calibration standard at each of the two ports, presenting a load calibration standard and measuring the reflection characteristic for each of the two ports to provide load data, converting the load data to the time domain to provide time domain impulse response load data, and gating the time domain impulse response load data based on the locations of the high reflection calibration standard at each of two ports. The method further includes reconstructing frequency domain load data from the gated time domain data, connecting the two ports together and determining forward and reverse transmission characteristics, and calculating systematic error coefficients for the VNA based on the reconstructed frequency domain data and the forward and reverse transmission characteristics. | 05-03-2012 |

20090069594 | Process and Catalyst for Oxidizing Aromatic Compounds - Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise at least two metal or metalloid elements, at least one of which is palladium, platinum, vanadium or titanium, and at least one of which is a Group 5, 6, 14 or 15 metal or metalloid. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such a catalytic composition in a liquid reaction mixture. | 03-12-2009 |
20090088585 | Process and Catalyst for Oxidizing Aromatic Compounds - Catalytic compositions for conversion of substituted aromatic feed materials to oxidized products comprising aromatic carboxylic acid derivatives of the substituted aromatic feed materials comprise a combination comprising a palladium component, an antimony component and/or a bismuth component, and one or more Group 4, 5, 6 or 14 metal or metalloid components. A process for oxidizing substituted aromatic feed materials comprises contacting the feed material with oxygen in the presence of such a catalytic composition in a liquid reaction mixture. | 04-02-2009 |
20090118536 | Process for the Production of Aromatic Carboxylic Acids in Water - A process is disclosed for producing at least one aromatic carboxylic acid by contacting a liquid reaction mixture comprising an aromatic feedstock and water with oxygen in the presence of a bromine-free metal catalyst composition wherein the metal catalyst composition has activity in the absence of bromine for oxidation of the aromatic feedstock with at least 80% conversion to oxidized aromatic derivatives of the aromatic feedstock and with at least 80% selectivity to the aromatic carboxylic acid. This process operates in water without the use of bromine at temperatures and residence times substantially the same as conventional processes for aromatic carboxylic acid manufacture, as well as with less total burning and with yields to product equivalent or higher than conventional processes. | 05-07-2009 |
