  • Patent number: 10198853
    Abstract: A processor receives sensor feedback indicating a focal point of an HMD user. The processor casts rays through an image volume based on the sensor feedback. Each of the rays is associated with a pixel of a rendered image. The rendered image has a first plurality of pixels associated with the rays and a second plurality of unassociated pixels. The rays comprise a first portion cast at or near the focal point and a second portion that is cast farther away from the focal point. A first spacing between rays of the first portion is less than a second spacing between rays of the second portion. The processor determines color values corresponding with each of the first plurality of pixels associated with the rays. The processor determines color values corresponding with each of the second plurality of unassociated pixels of the rendered image. The HMD displays the rendered image.

  • Patent number: 10199954
    Abstract: A voltage source converter includes DC terminals, a plurality of single-phase limbs, and a controller. Each single-phase limb includes a phase element and switching elements. Each limb is connected between the DC terminals and is controllable to generate an AC voltage at the AC side of the corresponding phase element so as to draw a respective phase current from a multi-phase AC electrical network. The controller is configured to selectively generate a modified AC voltage demand for at least one limb in response to an imbalance in the phase currents and/or a change in electrical rating of at least one limb. The controller is configured to selectively control, in accordance with the or the respective modified AC voltage demand, the or each corresponding limb independently of the or each other limb to modify the voltage at the AC side of its phase element and thereby modify the corresponding phase current.
