A method of controlling a dryer stand, which includes a receptacle on which a dryer for discharging drying air is mounted and which is rotatable in a horizontal direction, and an air purification unit, are provided. The method includes detecting the dryer mounted on the receptacle, charging a battery provided in the dryer when the dryer mounted on the receptacle is detected, determining whether a predetermined condition for air purification operation is satisfied, and operating the air purification unit when it is determined that the predetermined condition for air purification operation is satisfied, whereby it is possible to purify indoor air. A method of controlling the dryer while it is not on the stand is also provided.

A system and methods for the storage, and preservation of mechanical assets, including collectable automobiles, small airplanes and watercraft in a storage unit. The storage unit includes a plurality of asset modules. The volume of each asset module is variable. The atmosphere of each asset module may be controlled by a control system. Control of the atmosphere of each asset module includes control of parameters including the type of gas each atmosphere is composed of and the temperature, the pressure and relative humidity of each atmosphere. These parameters may be monitored and controlled from a remote location.

An apparatus is provided for controlling environmental conditions using a fan and a light in connection with a building having a space including a partition, such as a wall. The apparatus may include a control adapted for being mounted to the partition and for coordinating the control of the fan and the light based on a sensed condition, such as temperature or occupancy. Groups of like devices for controlling environmental conditions may be similarly controlled, such as using control. Control may also provide an indication of an operational state of the device(s) controlled by it, or provide for control based on a preference of one or more people upon detecting their presence. Related methods are also described.

The present disclosure relates to a sensor assembly and a control method therefor. The sensor assembly according to the present disclosure may include a plurality of gate lines, at least one detection line, and a plurality of sensors respectively disposed at portions where the plurality of gate lines intersect with the at least one detection line. In this case, the plurality of sensors include an olfactory sensor, a temperature sensor, and a humidity sensor.

An optical module includes a shell, a circuit board, a light-emitting device, a sensor assembly and a processor. The circuit board is disposed in the shell. The light-emitting device is disposed in the shell, and includes a non-hermetically sealed cover, a laser chip and a thermo electric cooler. The thermo electric cooler is disposed in the cover and is configured to adjust a temperature of the heat exchange surface of the thermo electric cooler connected to the laser chip. The sensor assembly is disposed on the circuit board and is configured to detect ambient data inside the optical module, the ambient data including at least ambient humidity. The processor is disposed on the circuit board, and is configured to receive the ambient data detected by and sent from the sensor assembly, and control the thermo electric cooler to adjust the temperature of the heat exchange surface of the thermo electric cooler to a target temperature according to the ambient data.

A system and a method include receiving, by a processor, from environmental sensors, environmental output data measurements. The environmental sensors are located at a site location. An health impact scoring algorithm computes a plurality of health impact scores from the environmental output data measurements. An overall health impact score at the site location is computed from the any of the health impact scores having a lowest value. A machine learning model generates at least one recommendation for remediating at least one verified environmental hazard type. At least one of the overall health impact score, the at least one verified environmental hazard type, or the at least one recommendation are displayed on a computing device. An instruction is sent to environment-controlling equipment located at the site location to change an operational parameter of the environment-controlling equipment to mitigate the at least one verified environmental hazard type.
