| 20090068747 | APPARATUS FOR EMITTING AND DETECTING LIGHT IN A NUCLEIC ACID AMPLIFICATION REACTION - Subject of the present invention is to provide an apparatus, an instrument, and a method particularly useful in multiplex PCR applications permitting short sample measuring times of many samples combined with high sensitivity. | 03-12-2009 |
| 20110129930 | INSPECTION METHOD AND APPARATUS - In an embodiment, there is disclosed an inspection method for detecting the presence of imprintable medium on an imprint lithography template. The method includes contacting the imprint lithography template with a marker, the marker being attachable to imprintable medium that may be on the imprint lithography template, the marker being configured to interact with incident radiation when attached to the imprintable medium, directing radiation at the imprint lithography template, and measuring radiation re-directed by the imprint lithography template to attempt to detect presence of a marker that has attached to the imprintable medium, from the interaction of the marker with the incident radiation, and thus detect the presence of imprintable medium to which the marker is attached. | 06-02-2011 |

| 20120028360 | Apparatus and Method for Combustion Analysing a Sample - Apparatus and method for combustion analysing a sample comprising determining incomplete combustion in a combustion analyser having a combustion chamber. A sample is supplied to the combustion chamber and combusted to produce combustion products. A target gas characteristic of incomplete combustion of the sample is detected in the combustion products by a target gas sensor. The target gas may be carbon monoxide, methane, methanal and/or methanol, among others. Whether incomplete combustion of the sample has occurred may be determined. A signal indicative of incomplete combustion is output from the target gas sensor and the combustion products can be directed to waste using a valve disposed upstream of the target gas sensor. | 02-02-2012 |
