Provided is a transmissive display apparatus capable of naturally combining a projection image on a real space scene. A beam splitter splits a light incident from a real space scene into first and second portions. An image sensor generates a real space image according to the second portion of the incident light. A light modulator passes at least a part of the first portion of the incident light according to a masking image. A control and projection image generation unit selects a target object and generates the masking image based on a target object area to cause a light modulator to block a foreground of the real space scene and pass a background of the real space scene. A projection unit generates a projection image light corresponding to the projection image combines the projection image light with a part of the first portion of the incident light.

An operating unit (2) sets ventilation parameters of a control unit (11) of a ventilator (1) that includes a gas dispensing device (10) for ventilation gases. The operating unit includes a display unit and an ventilation parameters input element (23, 24). Two or more of the parameters are linked via a relation condition stored in a relation storage module (40). A relation monitor (3) includes a deviation detector (31) detecting a transgression of the relation condition during parameter setting, and outputs warning information via a warning unit (32). This avoids a need for an operator to note the sometimes complicated connections and dependencies expressed in the relations during the parameter setting. The warning may be sent before the new setting value is sent from the operating unit to the control unit. Operating safety is increased and a risk of setting errors is minimized.

A port assembly for controlling fluid flow through a flow port of a port sub. The port assembly comprises a dissolvable barrier, a burst disk for protecting the dissolvable barrier from fluids inside the port sub, and optionally a protective layer for protecting the dissolvable barrier from external fluids. When the burst disk is ruptured by increased fluid pressure inside the port sub, the dissolvable barrier starts disintegrating from exposure to the fluid. When the dissolvable barrier and protective layer are broken through, a flow passage is opened in the port assembly to permit fluid flow therethrough. The flow passage may be positioned tangentially in the port sub. The breakthrough time of the dissolvable barrier may be preconfigured by providing one or more thinner areas therein and/or placing a corrosive material in the port assembly.

Apparatus, systems, and methods for providing a rearward view of an aircraft. The system, apparatus, and methods include one or more cameras disposed on an aft portion of a fuselage of the aircraft, a heads-up display is within a cockpit of the aircraft, and a heads-up control. The heads-up control receives image data from the one or more cameras and generates an image on the heads-up display based on the image data from the one or more cameras to provide a rearward view of an area behind the aircraft. The heads-up control may be configured to determine when an aerial object is within a predetermined range behind the aircraft and responsively generate the image on the heads-up display based on the image data from the one or more cameras to provide a rearward view of an area behind the aircraft in which the aerial object is located.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for parallelization of GPU composition with DPU topology selection. A processor may receive an indication of a plurality of application layers for composition at a first processor (e.g., a DPU) and a second processor (e.g., a GPU). The processor may select one or more first application layers of the plurality of application layers for attempted composition at the first processor and one or more second application layers of the plurality of application layers for composition at the second processor. The processor may transmit each of the one or more first application layers to the first processor for composition and each of the one or more second application layers to the second processor for composition.
