Patent number: 11917126Abstract: An augmented reality, virtual reality, or other wearable apparatus comprises an eye tracking device comprising an image sensor, a lens, and one or more processors. In some embodiments, the lens comprises a marker, and the one or more processors are configured to receive an image from the image sensor, wherein the image shows the marker, determine a distance from the image sensor to the marker based on the image, and change a calibration parameter of an eye tracking algorithm based on the distance. In some embodiments, the one or more processors are configured to receive image data from the image sensor, wherein the image data corresponds to an image as observed through the lens, determine a level or pattern of pincushion distortion in the image based on the image data, and change a calibration parameter of an eye tracking algorithm based on the level or the pattern of pincushion distortion.Type: GrantFiled: February 24, 2023Date of Patent: February 27, 2024Assignee: Tobii ABInventors: Jonas Andersson, Anders Clausen, Richard Hainzl, Anders Kingbäck, Simon Olin, Mark Ryan, Daniel Tornéus, Björn Nutti, Torbjörn Sundberg, Catarina Tidbeck, Ralf Biedert, Niklas Blomqvist, Dennis Rådell, Robin Thunström

Patent number: 8795980Abstract: An improved method for assessing previous ethanol exposure comprises the steps of obtaining a sample from the body of a subject; quantitatively determining the level of one or several bio-precursors of phosphatidylethanol (PEth) (Formula I) or ethyl-sphingomyelin and the level of the corresponding one or several PEth (Formula II) or ethyl-sphingomyelin homologues in the sample; and obtaining a ratio between the level of one or several bio-precursors of PEth or ethyl-sphingomylein and the level of the corresponding one or several PEth- or ethyl-sphingomylein homologues. The ratio is indicative of previous ethanol consumption of the subject. Furthermore, a method for assessing previous absolute ethanol consumption can be accomplished by correlating the ratios of PEth precursor and PEth homologue levels in subjects to ratios obtained from reference subjects with known previous ethanol consumption.Type: GrantFiled: July 8, 2011Date of Patent: August 5, 2014Assignee: Pethmark ABInventors: Anders Andersson, Anders Isaksson
