Abstract: Methods, systems, and computer program products for direct assignment of physical devices to confidential virtual machines (VMs). At a first guest privilege context of a guest partition, a direct assignment of a physical device associated with a host computer system to the guest partition is identified. The guest partition includes the first guest privilege context and a second guest privilege context, which is restricted from accessing memory associated with the first guest privilege context. The guest partition corresponds to a confidential VM, such that a memory region associated with the guest partition is inaccessible to a host operating system. It is determined, based on a policy, that the physical device is allowed to be directly assigned to the guest partition. Communication between the physical device and the second guest privilege context is permitted, such as by exposing the physical device on a virtual bus and/or forwarding an interrupt.

Abstract: A variable resistance door stay apparatus is disclosed. The door stay is provided with an adjustable tightening nut that slides inside a longitudinal slot in a ridged member. A method is disclosed for proving variable resistance to rotational of a door.

Abstract: Techniques are disclosed relating to determining or executing a survey pattern for a marine seismic survey vessel. The survey pattern may be determined based on a determined subsurface illumination area. The subsurface illumination area may be identifiable from primary reflections and higher-order reflections detected by sensors disposed in a sensor streamer configuration that may be towed behind the survey vessel. The sensor streamer configuration may include a plurality of streamers.

Abstract: A two piece graft fixation arrangement includes a graft block engageable with a graft and a transverse member engageable with the graft block to fix the graft block in a bone tunnel. Instruments and methods are presented for installing a graft in a bone tunnel and anchoring the graft with a transverse member placed through a transverse bore intersecting the bone tunnel.

Abstract: A multi-sample blood collection needle device is provided with safety features that minimize the possibility of an accidental needle-stick. The device includes a rigid shroud that secures a stationary rear hollow needle,and a forward needle telescopically mounted upon the rear needle. A coil spring causes the forward needle to retract rearwardly upon the stationary rear needle, thereby disposing the point of the forward needle safely within the shroud.
