Method for representing virtual information in a view of a real environment

A method for representing virtual information in a view of a real environment comprises the following steps: providing at least one virtual object (10) having a global position and orientation with respect to a geographic global coordinate system (200), together with first pose data (PW10) permitting a conclusion to be made on the global position and orientation of the virtual object, in a database (3) of a server (2), taking at least one image (50) of a real environment (40) by means of a mobile device (30) and providing second pose data (PW50) permitting a conclusion to be made as to at which position and with which orientation with respect to the geographic global coordinate system (200) the image was taken, displaying the image (50) on a display (31) of the mobile device, accessing the virtual object (10) in the database (3) of the server (2) and positioning the virtual object (10) in the image (50) shown on the display on the basis of the first and second pose data (PW10, PW50), manipulating the virtual object (10) or adding a further virtual object (11) by corresponding positioning in the image (50) shown on the display, and providing the manipulated virtual object (10) together with modified first pose data (PW10) in accordance with the positioning in the image (50) or the further virtual object (11) together with third pose data in accordance with the positioning in the image (50) in the database (3) of the server (2), the modified first pose data and third pose data each permitting a conclusion to be made on the global position and orientation of the manipulated or further virtual object. Instead of with an image of the real environment, the method can also be performed analogously using a view of an HMD, for example.

System for enhancing intensity modulated radiation therapy, program product, and related methods

A system to provide enhanced computational efficiency in determining dose in a media of varying density from a high-energy radiation-beam for radiation treatment, program product, and related methods are provided. The system can include a radiation treatment planning computer and radiation treatment planning program product stored in the memory of the radiation treatment planning computer and adapted to enhance optimization of a radiation treatment plan for delivering radiation to a complex medium defining a patient volume. The radiation treatment planning program product provides functions including those for predetermining a delivery machine-dependent representation of radiation dose for a plurality of different electron densities selected over a preselected representative range, predetermining a depth-dependent representation of central axis properties of a pencil beam passing through a complex medium for each of a plurality of pencil beams, and determining with constant time computational complexity radiation dose for each of a plurality of points of interest in a heterogeneous medium having a complex spatial distribution of heterogeneous electron densities by applying the predetermined machine-dependent and depth-dependent representations.

Refrigeration apparatus

There is provided a refrigeration apparatus in which a refrigerant accumulating in non-operating outdoor units is supplied to an outdoor unit being operated in which a shortage of refrigerant occurs without starting the compressors of the non-operating outdoor units. In the control method for the refrigeration apparatus in which to refrigerant piping 10 installed between the indoor side and the outdoor side, a plurality of outdoor units 30A, 30B each including a compressor 31, a directional control valve 34, an outdoor heat exchanger 35, an outdoor expansion valve 36, and an accumulator 37 are connected in parallel on the outdoor side, and each of the outdoor units is provided with a hot gas bypass circuit 38 that includes a solenoid valve 38a and an expansion mechanism 38b arranged in series, and is connected between high-pressure side piping 33a on the discharge side of the compressor and low-pressure side piping 33b on the accumulator side, if a shortage of refrigerant occurs when air cooling operation is performed in a state in which only the outdoor unit 30A is operated and other outdoor units 30B are not operated, the solenoid valves 38a of the non-operating outdoor units 30B are opened so that the refrigerant accumulating in the non-operating outdoor units 30B is supplied to the outdoor unit 30A via the hot gas bypass circuit 38 and the low-pressure piping 33b.
