Abstract: Examples are disclosed herein that relate to the display of mixed reality imagery. One example provides a mixed reality computing device comprising an image sensor, a display device, a storage device comprising instructions, and a processor. The instructions are executable to receive an image of a physical environment, store the image, render a three-dimensional virtual model, form a mixed reality thumbnail image by compositing a view of the three-dimensional virtual model and the image, and display the mixed reality thumbnail image. The instructions are further executable to receive a user input updating the three-dimensional virtual model, render the updated three-dimensional virtual model, update the mixed reality thumbnail image by compositing a view of the updated three-dimensional virtual model and the image of the physical environment, and display the mixed reality thumbnail image including the updated three-dimensional virtual model composited with the image of the physical environment.

Abstract: An apparatus comprising a multi-tenant datastore and a processor coupled to the multi-tenant datastore, wherein the processor is configured to receive a request comprising one or more security tokens, wherein the one or more security tokens comprise identification information, and generate a query based on the request to access the multi-tenant datastore, wherein generating the query comprises deriving a query scope based on the one or more security tokens.

Abstract: Some embodiments of the present invention provided an impedance-transforming arrangement comprising a plurality of microwave power transistors 41, and at least one intermediate impedance-transforming or matching device 30. The matching device comprises a plurality of elongate microwave transmission lines 31 provided in or on at least one dielectric substrate 32, extending across or through the dielectric substrate. The microwave transmission lines are coupled at one end to the gate pads 47 of the transistor and at the input ends to a signal input terminal for the transmission line. The transmission lines are substantially directly coupled to one another by means of resistive elements 35 providing a current flow path between the two transmission lines in order to reduce any residual tendency to instability caused by manufacturing variations or misalignment in the assembly process.
