A server for a control system for cooling systems is disclosed. The server includes a memory device configured to store instructions and a processor communicatively coupled to the memory device and a plurality of cooling systems. Each of cooling systems includes a motor, a sensor, a local memory, and a microprocessor communicatively coupled to the motor, the sensor, the local memory. The microprocessor is configured to control operation of the motor according to settings defined by configuration data stored in the local memory. In response to reading the instructions, the processor is configured to receive, from the sensor of each of the cooling systems, first sensor data, generate first configuration data by executing a first algorithm on the first sensor data, and instruct the microprocessor of at least one cooling system to write the first configuration data to the local memory of the at least one cooling system.

A refrigerator includes a cabinet having a storage space and a door to open and close the storage space. The door includes a panel assembly including a front panel, a door frame connected to the panel assembly, a door liner connected to the panel assembly and the door frame and to define an insulating space, in which an insulator is disposed, together with the panel assembly and the door frame, and a sensor module installed on the door frame to sense a knock input applied to the front panel. The door frame includes a front wall that is in contact with the front panel and a rear wall spaced apart from the front wall and configured to define an accommodation space, in which the sensor module is accommodated, together with the front wall.

Disclosed is a refrigerator. The refrigerator includes a body which includes a storage compartment, a door which opens and closes the storage compartment and includes a dispenser, a water tank case disposed in the door, a water tank separably mounted in the water tank case, a water level sensor configured to sense a water level inside the water tank when the water tank is mounted in the water tank case, and a water tank valve configured to guide water supplied from a water supply source to the dispenser or the water tank and to prevent water from being supplied to the water tank when the water level sensor senses that a certain amount of water is stored in the water tank.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

An insulated structure comprises a first panel and a second panel coupled to the first panel. The first and second panels define an insulating cavity therebetween. A port is defined by the second panel. The port is an opening into the insulating cavity. A connector is coupled to the second panel. A tube is coupled to the connector and extends parallel along the second panel.

A refrigerator appliance or door assembly may include an enclosing body, a liquid reservoir, a level sensor, a water valve, and a liquid dispenser. The enclosing body may define an exterior surface and an interior surface. The liquid reservoir may be defined within the enclosing body between the exterior surface and the interior surface. The level sensor may be mounted to the liquid reservoir. The level sensor may be configured to detect a water volume within the liquid reservoir. The water valve may be mounted upstream from the liquid reservoir to selectively direct water thereto based on the detected water volume. The liquid dispenser may extend from the liquid reservoir and through the interior surface to an outlet aperture to selectively dispense water from the liquid reservoir.

A display case includes multiple walls that define an inner volume, a door, a door actuator, a gesture sensor, and a controller. The door is transitionable between an open position for access to the inner volume and a closed position. The door actuator is configured to transition the door between the open position and the closed position. The gesture sensor is configured to detect a gesture performed by a user. The controller includes a processing circuit configured to obtain sensor data from the gesture sensor that indicates the gesture performed by the user. The processing circuit is further configured to determine if the user has performed a reference gesture using the sensor data. The processing circuit is further configured to operate the door actuator to transition the door between the open position and the closed position in response to determining that the user has performed the reference gesture.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

A refrigerator includes a water sensor unit secured to a case to overlap with a lower surface of a water tank, so that the water level sensor unit may maintain a constant position and operational stability may be increased, regardless of whether the water tank is mounted or demounted, and the upper surface of the water level sensor unit is inclined toward the front surface of the water level sensor unit, thereby reducing an operational error due to residual water.

It is provided a sensor device comprising: a proximity sensor; a processor; a wireless communication module; and a memory. The memory stores instructions that, when executed by the processor, cause the sensor device to: receive a user input signal; determine when the received user input signal matches a signal template being associated with an event; store in the memory a record indicating an occurrence of the event associated with the user input signal; and transmit, once the wireless communication module is active, any stored records.
