Abstract: A lens calibration system for calibrating a lens of an image capture device, the lens calibration system comprising: a processor configured to receive from the image capture device a series of image frames of a scene at different rotational positions of the image capture device; The processor being configured to: Identify in the series of image frames elements representing a first marker located at a first known distance from the image capture device and a second marker located at a second known distance from the image capture device, the first and the second known distances being different to one another; track the identified elements representing each marker across the series of image frames; process the tracked elements to determine a characteristic parameter of the lens of the image capture device; and build a lens model for the image capture device in dependence on the determined characteristic parameter of the lens.

Abstract: A palatable, single serving dietary supplement of amino acids that may be taken as a nutritional aid to improve health and well-being by promoting higher quality sleep, enhancing repair of muscular tissue after strenuous exercise in part through boosting the natural production of human growth hormone, enhancing the immune system, improve gut barrier function, aiding in responses to upper respiratory viral pathogens, reversing side effects from the over use of nutritional energy drinks with stimulants and simple sugars and reverse the side effects of excess signaling through the cortisol pathway resulting from chronic environmental stress.

Abstract: The present invention is a method and apparatus for determining oil based mud contamination of a hydrocarbon fluid obtained from a wellbore during a formation testing. The invention includes receiving a model for simulating the contamination and receiving an empirical equation for computing the contamination. At a given pumping time, a simulated contamination is generated based on the model and an empirically computed contamination is generated based on the first empirical equation. The simulated contamination and empirically computed contamination are compared and a determination as to which is more reliable is made. Revision of the first model or first empirical equation based is then performed.
