Patent number: 9029161Abstract: A method and apparatus for dating a body sample, such as blood, includes taking at least one spectroscopic measurement of the sample at at least two predetermined positions in the spectrum having spectral characteristics corresponding to at least two predetermined substances present in the sample that have a time varying relationship with each other. A measured relative concentration of each of the predetermined substances is then determined from the measurement, and the measured relative concentrations of the two predetermined substances is compared with a known variation of the relative concentrations of the two predetermined substances over time. A good fit of the measured relative concentrations to the known variation of the relative concentrations is then determined, so as to provide an indication of the age of the sample. Alternatively, instead of measuring the relative concentrations of each of the predetermined substances, the rate of change of the relative concentrations is determined.Type: GrantFiled: July 11, 2011Date of Patent: May 12, 2015Assignee: Academisch Medisch CentrumInventors: Maurice Aalders, Rolf Bremmer

Patent number: 8750952Abstract: A method and apparatus for dating a body sample, for example a sample of body fluid involves taking a series of spectroscopic measurements of the sample, each measurement in the series including at least two predetermined positions in the spectrum. The positions have spectral characteristics corresponding to two or more predetermined substances present in the sample that have a time varying relationship with each other. The measurements in the series are spaced in time. A concentration of each of the substances present in the sample is then determined from each of the spectroscopic measurements at each point in time. Next, a ratio of the concentrations of the two predetermined substances at each point in time is determined and then the ratios of the concentrations of the two predetermined substances over time are analyzed to estimate when the concentrations of the two substances were at a limit of their concentrations, thereby providing an indication of the age of the sample.Type: GrantFiled: April 21, 2009Date of Patent: June 10, 2014Assignee: Academisch Medisch CentrumInventor: Maurice Christian Gerard Aalders
