Described may be a modular network communication system for use in a foundational structure, for the inclusion of new foundational structure construction, or configured for mobility between different foundational structures. The network communication system may be configured to support a broad array of network-related communications. The foundational structure's modular network communication system may have a controller, a power connection point, a communication protocol, and may include one or more than one network node. The controller unit may have processing circuitry and may be configured to utilize a communication protocol for controlling the foundational structure's information flow of the modular network communication system. Additionally, the controller may be further configured to communicate with at least one, but also more than one network-connected device which may or may not be connected to the internet.

A duct for guiding air outside an image forming apparatus to a charging device includes: a first flow passage; a second flow passage bent from the first flow passage and extending in a direction orthogonal to a rotational direction and a rotational axis direction of a photosensitive drum, the second flow passage being provided with an outlet; and a plurality of flow dividing plates provided in the second flow passage, the plurality of flow dividing plates being disposed in parallel along the rotational axis direction and forming a third flow passage between the flow dividing plates adjacent to each other, in which a relationship between a length in the orthogonal direction and a length in the rotational axis direction of the third flow passage is a predetermined relationship.

A condensate lifting device, including: a condensate receiving tank and a pump for lifting the condensates received in the tank. The pump is mounted on a first support for holding and/or guiding the tank or a second support carrying the tank, so that the tank or the second support is movable, in translation and/or in rotation, relative to the first support, so as to be able to take at least two positions: a working position, wherein the tank is connected to the pump; and a drainage position, wherein the tank is disconnected from the pump and displaced relative to the first support, so as to allow an operation of cleaning and/or draining the condensates.

In accordance with at least one aspect of this disclosure, an adjustable vent tube joint for passing airflow therethough includes, a first segment, a flange extending radially from an outer diameter of the first segment, configured to mount to the vent tube joint to a structure, a second segment rotatably connected to the first segment, and a third segment rotatably connected to the second segment. In accordance with at least one aspect of this disclosure, an adjustable vent pipe can include, a first segment and a second segment concentric with the first segment, the second segment being slidable relative to the first segment. In accordance with at least one aspect of this disclosure, an insert for an exhaust termination can include, a frame configured to fit within an existing louvered exhaust termination, a hinge member, and a flap operatively connected to the frame via the hinge member configured to open with an exhaust flow to connect a dryer exhaust outlet to an ambient external environment through the exhaust termination.

An air conditioner of present invention comprises a housing having an outer panel forming the exterior and an opening formed on the outer panel, a heat exchanger configured to exchange heat with air flowing into the housing, and a door unit configured to open or close the opening by moving forward or backward from the opening through which the heat exchanged air is discharged. Wherein the door unit comprises a door blade configured to open or close the opening, a door operating part configured to move the door blade forward or backward, and a controller configured to control the air discharged from the opening to be moved forward from the opening in a straight line or to be discharged radially from the opening by controlling a distance between the door blade and the opening.
