Abstract: Proposed is a method for quantifying water and lipid contents in turbid media. Methods for quantifying water and lipid contents through non-invasive methods in turbid media in which scattering occurs upon penetration of near-infrared rays have yet to be proposed. In addition, existing apparatuses and methods for measuring body composition use frequency-domain and time-domain diffuse optical spectroscopy or infrared spectroscopy to measure water and lipid contents in tissue, whereby there are limitations that hardware configurations become complicated, and mass production and sales are subject to constraints. To solve such problems, proposed is a method for quantifying water and lipid contents in turbid media using narrowband diffuse reflectance spectroscopy, which uses only a near-infrared band in a range of 900 to 1,000 nm, configured such that the water and lipid contents can be accurately quantified in tissue through a simpler configuration than that in existing methods.

Abstract: Some examples described herein relate to computer interfaces and authentication protocols for securely linking and transferring content between online accounts. In one example, a system can provide a graphical user interface (GUI) with multiple interactive interface pages, through which a user can selectively transfer content from a first online account to a second online account. For example, the user can select to transfer points from the first online account to the second online account. The system can then transfer of the selected content from the first online account to the second online account. To perform this transfer, the system can employ multiple layers of authentication and other security mechanisms. For example, the system can employ two or more layers of authentication and a unique external identifier to perform the transfer. Following the transfer, the GUI can be updated to reflect the results of the transfer.
