摘要: Systems and methods for dynamically controlling vergence and focus for a see-through head-mounted display (ST-HMD) used as part of an augmented reality (AR) system are disclosed. The ST-HMD (40) allows a user (30) to view left and right images (150L, 150R) through corresponding left and right eyepieces (104L, 104R) so that a single virtual object (150V) based on the right and left images as seen at a real object such as a screen (20). When the user moves relative to the real object, however, the vergence changes and the virtual object does not appear in focus at the real object. Changes in the vergence are compensated by tracking the user's head position with a tracking unit (350) and providing the tracking data to a controller (180). Based on the tracking data and the interpupilary distance (IPD) of the user, the controller calculates the offset (H) needed to be imparted to the images formed in the eyepieces to maintain the vergence of the virtual object at the real object even when the user's position changes relative to the real object.

摘要: A method of determining calcium metabolism in a patient comprises the steps of administering radioactive calcium isotope 41Ca to the patient, allowing a period of time to elapse sufficient for dissemination and reaction of the radioactive calcium isotope 41Ca by the patient, obtaining a sample of the radioactive calcium isotope 41Ca from the patient, isolating the calcium content of the sample in a form suitable for precise measurement of isotopic calcium concentrations, and measuring the calcium content to determine parameters of calcium metabolism in the patient.

摘要: A carrying bag, particularly a backpack, comprises a receiving container for receiving objects to be taken along, and a carrying device connected to the receiving container. The carrying device is decoupled in its movements from the receiving container by the provision of string lines which can be displaced in the direction marked by the arrows.
