An image acquisition unit (211) acquires a photographed image obtained by photographing an air-conditioning indoor unit including a plurality of air outlets. An image collation unit (212) collates a template image wherein an air-conditioning indoor unit of a same type as the air-conditioning indoor unit is shown with the photographed image. An air outlet identification unit (213) determines an air outlet identifier of each air outlet in the photographed image based on a collation result, and on air outlet identification data indicating an air outlet identifier to be associated with each air outlet in the template image. An identification result display unit (214) displays the photographed image by superimposing the air outlet identifier on each air outlet in the photographed image.

The present disclosure presents infant soothing devices which provide timed, color, and intensity controlled light and sound projections to assist in sleep therapy. The devices may be part of a smart nursery which has a number of electronically connected devices which communicate with a central electronic application to gather information and provide operation instructions to the devices. The smart nursery may be connected to a larger network to provide feedback and controllability outside of the nursery.

A computer system provides intelligent context-based control of air flow. An identity of a user and a location of the user within an area that includes one or more vents associated with a climate control system are identified. User preferences are determined based on the identity of the user. Characteristics of air flow in the area are adjusted based on the user preferences the user and the location of the user, wherein the characteristics of the air flow comprise one or more from a group of: a direction, and a flow rate. Embodiments of the present invention further include a method and program product for providing intelligent context-based control of air flow in substantially the same manner described above.

Systems and methods are configured to control operation of an HVAC system providing climate control for a zone of a structure. In various embodiments, a constrained optimization problem is performed to set control commands for controlling operation of the HVAC system to achieve one or more objectives while providing a supply air flow at an air temperature and a humidity ratio for the zone at a future time. For instance, the optimization problem may include a cost function having constraints based on a desired temperature setpoint and a humidity ratio for the zone. A value is set for each control command based on the performance of the constrained optimization problem to achieve at least one of the objectives and as a result, the supply air flow at the air temperature and humidity ratio is provided by the HVAC system at the future time to the zone based on the values.
