2486 results about "Sample processing" patented technology

Sample processing is a process done to a sample to prepare it for testing. In the case of the water samples that were collected, the first step was to filter the sample. This is an important step due to the fact that the sample that was used wasn’t entirely pure. The accuracy of the results depends upon the purity of the sample provided.

Whitening matched filter for use in a communications receiver

A novel and useful whitening matched filter (WMF) for use in a communications receiver. The WMF is constructed by cascading a matched filter and a noise-whitening filter. The response of the matched filter is derived from the time reversed complex conjugate of the channel impulse response. The whitening filter is derived by extracting the minimum phase portion of the mixed phase channel impulse response using homomorphic deconvolution. The whitening filter is implemented using either an FIR or IIR filter adapted to process the data received before and after the training sequence using a minimum phase system in a direction in time opposite to that of the direction of corresponding data sample processing performed by the equalizer.

Sanitary swab collection system, microfluidic assay device, and methods for diagnostic assays

Biohazard specimen collection containers are provided with an external disposable skin, that is stripped away and discarded after the biohazardous specimen is collected, thus reducing or eliminating objectionable or dangerous residues on the outside surfaces of the container. Further, we teach that the sample collection container with external disposable skin may also serve as an integrated microfluidic biosample processing and analytical device, thereby providing a single entry, disposable assay unit, kit and system for “world-to-result” clinical diagnostic testing. These integrated assay devices are provided with synergic, multiple safe-handling features for protecting healthcare workers who handle them. The modified collection containers and analytical devices find application, for example, in PCR detection of infectious organisms or pathogenic markers collected on a swab.

Variable valve apparatus and methods

Sample processing devices with variable valve structures and methods of using the same are disclosed. The valve structures allow for removal of selected portions of the sample material located within the process chamber. Removal of the selected portions is achieved by forming an opening in a valve septum at a desired location. The valve septums may be large enough to allow for adjustment of the location of the opening based on the characteristics of the sample material in the process chamber. If the sample processing device is rotated after the opening is formed, the selected portion of the material located closer to the axis of rotation exits the process chamber through the opening.
