IPC: G01N1/40
Filed: 2010-02-02
Abstract: Methods and systems are provided for the soft desorption of analyte from a sample, in which an optical beam absorbed within an irradiate zone of the sample causes vibrational excitations of a component within the sample. The optical beam, providing sufficient energy to superheat the component, is provided for a time interval that is less than the time duration required for the loss of energy out of the irradiated zone due to thermal diffusion and acoustic expansion. The superheated component thus drives ablation within the irradiated zone, resulting in the soft desorption of analyte without ionization and fragmentation. The ejected ablation plume may be directed towards the inlet of a mass analysis device for detection of the desorbed analyte, which is preferably ionized by a linear resonant photo-ionization step.

Abstract: A system and method for providing information for performing a registration correction for artillery employs two spaced apart optical imaging systems associated with a processing system. Outputs from the two imaging systems are monitored to detect potential shell trajectory events and then correlated to eliminate potential shell trajectory events not viewed by both optical imaging systems. Locations are determined for potential shell trajectory events viewed by both optical imaging systems. Shell firing data relating to firing of at least one shell is provided to determine at least one predicted trajectory time point for the shell, and this is used to identify a corresponding detected shell trajectory event. The time and location of the detected shell trajectory event can then be used in determining a registration correction for the artillery.

Inventor: MALLADI DURGA PRASAD
IPC: H04W24/10
Filed: 2007-11-06
Abstract: A method for a wireless communication includes receiving or storing a peak to average (PAR) back off value; and applying the PAR back off value to determine the transmission power and rate for SIMO and MIMO transmissions. In one aspect, the PAR  back off value is at least partially based on modulation type. In another aspect, the PAR back off value is more for higher order QAM than for QPSK. The power allocation algorithm for different UL MIMO schemes is described as follows. For MIMO without antenna permutation (e.g. per antenna rate control), different PAR back off values are considered for different data streams. For MIMO with antenna permutation or other unitary transformation such as virtual antenna mapping or precoding, the PAR back off are determined based on combined channel. The transmission data rate depends on power and also the receiver algorithms such as a MMSE receiver or MMSE-SIC receiver.

Title: Enzymatic hydrolysis of cellulose
Inventor: SJOEDE ANDERS
IPC: C12P7/06
Filed: 2011-06-16
Abstract: The present invention relates to a continuous process for the enzymatic hydrolysis of cellulosic biomass and to an apparatus for conducting said process. According to the present invention, a steady state is achieved in a reactor in regard to the hydrolysis reaction. Therein, cellulosic biomass of a high total solids content (preferably 10% or higher, further preferably between 15 and 30%) is continually added to said reactor, while at least partially hydrolyzed cellulosic biomass is continually removed from said reactor. The steady state is adjusted, i.e. the amount of cellulosic biomass added and the amount of at least partially hydrolyzed cellulosic biomass removed is adjusted, so that the retention time of a given portion of added cellulosic biomass in the reactor is longer than its "liquefaction time", i.e. the time period required to transform a solid slurry into a pumpable liquid during hydrolysis, i.e. the time required to lower the viscosity of the slurry to a value, which is acceptable for further processing.

Title: Method for adjusting interference signal space in bio-magnetic field measurements
Inventor: SIMOLA JUHA
IPC: A61B5/245
Filed: 2011-07-06
Abstract: The present invention introduces a method for adjusting interference signal estimates provided by multi-channel biomagnetic field measurements. A so-called Signal Space Separation method (SSS) is applied in the calculatory analysis of the measurement signals, providing for the division of the sources causing the fields in objects of interest and external interferences. When the signal basis representing the interferences has been estimated, this interference signal estimate is adjusted by measuring the fields without the object to be measured and without changing the sensor assembly. Interference components obtained in this manner are analyzed in such a way as to include only the most significant interference components. In addition, it is taken into account that only those forms of interference of the measured interference components are included which are not yet present in the calculated SSS model. Finally, an adjusted interference subspace is formed, by means of which signal processing and the analysis of the useful signals can be continued. In the invention, the incorrectly functioning signal channels can also be taken into account and equated with the external interferences. In one embodiment, the above-described process can also be performed for the signals of the internal basis, i.e. for the signals of interest.
