Abstract: A mixed-reality device includes a head-mounted display, a communication interface configured to wirelessly communicate with a remote touch-sensitive device, a logic machine, and a storage machine. The storage machine holds instructions executable by the logic machine to receive a pose of the touch-sensitive device in the physical space, receive, via the communication interface, a control signal that is based on a touch input to the touch-sensitive device, and in response to receiving the control signal, visually present, via the head-mounted display, a virtual object based on the pose of the touch-sensitive device.

Abstract: A compressor is disclosed herein. The compressor may include a shroud cavity. The compressor also may include a flow directing device positioned within the shroud cavity. The flow directing device may be configured to direct a flow within the shroud cavity.

Abstract: According to some aspects, a hybrid optic is provided. The hybrid optic comprises a capillary optic for receiving x-rays from an x-ray source at an entrance portion of the capillary optic and for providing x-rays at an exit portion of the capillary optic, and a grazing incidence multi-shell optic (GIMSO) coupled, at an entrance portion of the GIMSO, to the exit portion of the capillary optic to receive x-rays emerging from the exit portion of the capillary optic, the GIMSO including an exit portion for providing x-rays.
