A computing device comprises: a base portion; a display portion that is movably coupled to the base portion and includes a housing having a movable panel and one or more fixed panels; and a mechanical assembly that positions the movable panel away from the one or more fixed panels as the display portion opens away from the base portion.

A display device includes: a display panel; a stand disposed at a first side surface of the display panel; a blowing fan disposed inside the stand; and a duct disposed at a second side surface of the display panel and connected to the stand.

Fan assemblies are disclosed. Fan assemblies include an impeller with asymmetric design. For example, an impeller may include a first set of blades with one geometry and second set of fan blades with another geometry. This enables a dual-inlet centrifugal fan to generate different air flow performance characteristics for the air entering one fan inlet compared to the air entering the other fan inlet. The impeller, with different fan blade configurations, can better handle air flow entering the fan assembly through different inlets, particularly when the air flow conditions differ through the inlets due to impeding structures (e.g., motor, struts, etc.). As a result, air flow distribution from air leaving the impeller, including the locations associated with the different fan blade configurations, is relatively uniform. Beneficially, when air flow distribution uniformity increases, the fan assembly operates more efficiently, as air flow pressure losses due to flow separation are mitigated.

A display assembly system which detects abnormal operating conditions, such as gas recirculation or airway occlusion, is provided. An electronic display is located within a housing. Sensors measure characteristics of ambient air ingested by a thermal management subsystem. Weather conditions are gathered for a location, and measurements are received from the sensors regarding characteristics of the ingested ambient air. An alert is generated if the measurements change at a rate different from a rate of change of the weather conditions by at least a preterminal amount.

Embodiments of this application disclose a housing structure and a terminal device. The housing structure includes a bottom shell and a lifting shell. A first end of the bottom shell is connected to a first end of the lifting shell, a second end of the bottom shell and a second end of the lifting shell are spaced by a first distance, and space between the bottom shell and the lifting shell forms a heat dissipation channel. A heat dissipation panel is disposed on the bottom shell, a first surface of the heat dissipation panel is in contact with a heat emitting component, and a second surface of the heat dissipation panel is located in the heat dissipation channel. Therefore, the housing structure provided in the embodiments of this application can better dissipate heat for the heat emitting component in the bottom shell.

A display system includes a first enclosure dimensioned to seal within its interior against ingress of dust and water an electronic display device comprising a screen, the first enclosure having a pane for enabling viewing of the screen from the exterior of the first enclosure; and at least one heat transfer structure extending through a wall of the enclosure between the interior and the exterior, each of the at least one heat transfer structure including a heat pipe having a proximal end within the interior of the first enclosure and a distal end at the exterior of the first enclosure. A heat transfer system for transferring heat away from an enclosure is also provided.

A display assembly which detects abnormal operating conditions, such as gas recirculation or airway occlusion, is provided. An electronic display is located within a housing. An airflow pathway travels through the housing and is configured to accept, circulate, and exhaust air by way of one or more fans. One or more sensors measure characteristics of the air. Weather conditions for a location of the display assembly are gathered, measurements from the sensors are received, and a determination is made as to whether the measurements of the ingested air are within a margin of error expected measurements derived from the gathered weather conditions. An alert is generated if the measurements of the ingested air are not within the margin of error.

Particular embodiments described herein provide for an electronic device that can be configured to include a first housing, a second housing, where the second housing includes a fan, an inlet, and actuators, and a hinge, where the hinge rotatably couples the first housing to the second housing. When the first housing is rotated over the inlet, the actuators lower the inlet to create a gap between the inlet and the first housing. In some examples, the inlet includes slats and when the first housing is rotated over the inlet, a distance between each of the slats increases from a first distance to a second distance.

Field customizable airflow systems, and methods related to the same, are provided. A housing for an electronic display subassembly includes an intake and an exhaust for ambient air. A communications box located above the electronic display subassembly includes one or more electronic components, a convection aperture plate with one or more apertures, an intake portion, an exhaust portion, and one or more fans which cause a flow of ambient air to be accepted at the intake portion, circulated through each of the apertures in the convection aperture plate, and exhausted through the exhaust portion when activated.

A display system with fan control which includes a display module, a fan, a temperature detector and a fan controller is provided. The fan is configured to generate an air flow in the display system. The temperature detector is configured to detect temperature within the display system. The fan controller is configured to generate a control signal to control a rotational speed of the fan based on the detected temperature and a first time period since the detected temperature reaches a first threshold and in which the detected temperature remains equal to or higher than the first threshold. The fan controller remains the rotational speed of the fan unchanged when the detected temperature is lower than the first threshold.
