grade lithium hydroxide and lithium carbonate from high-impurity lithium sources. The method 
comprises steps for preparation of a refined lithium salt solution, preparation of battery grade 
lithium hydroxide, preparation of high purity grade lithium hydroxide, preparation of high 
purity grade lithium carbonate and preparation of battery grade lithium carbonate. The system 
comprises a refined lithium salt solution preparation subsystem, a battery grade lithium 
hydroxide preparation subsystem, a high purity grade lithium hydroxide preparation subsystem, 
a high purity grade lithium carbonate preparation subsystem and a battery grade lithium 
carbonate preparation subsystem arranged in turn according to production sequence. To treat the 
high-impurity lithium sources varying in lithium contents, impurity categories and impurity 
contents, the invention proposes differentiated combinations of physical and chemical treatment 
methods to adapt to quality variations of the high-impurity lithium sources and meet quality 
requirements for production of the battery grade and high purity grade lithium hydroxide and 
lithium carbonate products. Compared with the existing production processes and technologies, 
the method of the invention is widely adaptable, most of by-products are recyclable, and the 
process is economical and environmentally friendly.

Granted: 2023-05-04
Abstract: Systems and methods for using determination of base modification in 
analyzing nucleic acid molecules and acquiring data for analysis of nucleic acid molecules 
are described herein. Base modifications may include methylations. Methods to determine 
base modifications may include using features derived from sequencing. These features may 
include the pulse width of an optical signal from sequencing bases, the interpulse duration of 
bases, and the identity of the bases. Machine learning models can be trained to detect the base 
modifications using these features. The relative modification or methylation levels between 
haplotypes may indicate a disorder. Modification or methylation statuses may also be used to 
detect chimeric molecules.

Abstract: A multiple single use optical sensor includes a series of continuous sensor stripes deposited on a substrate web. At least one sample chamber is adapted to extend transversely across a discrete portion of the series of sensor stripes to facilitate analysis of a sample disposed therein. The sample chamber may be moved, or additional sample chambers provided to enable subsequent measurements of additional samples at unused discrete portions of the sensor stripes. The continuous nature of the sensor stripes provides consistency along the lengths thereof to enable calibration data obtained from one discrete portion of the sensor stripes to be utilized for testing an unknown sample an other discrete portion of the sensor stripes. This advantageously eliminates the need for any particular discrete portion of the sensor stripes to be contacted by more than one sample, for improved sensor performance.
