Disclosures of the present invention describe a plant light raising and lowering apparatus. Particularly, a control module is configured for controlling a rope winch to complete at least one inching rotation along a clockwise direction or a counterclockwise direction, such that a base is driven by the rope winch so as to have an upward inching movement or a downward inching movement. Moreover, a counter is adopted for counting the direction, times and/or frequency of the inching rotation, and therefore the control module is able to know a total moving distance of the base by using the inching movement recording unit to record each time of the upward inching movement and each time of the downward inching movement. Therefore, a user is able to control the base to move back to a specific position such as an initial position or a previously-staying position.

A system for detecting misalignment of a light fixture uses a gateway controller device to receive images captured by an aerial drone. The gateway controller will select a group of the images and, for each image in the group: identify a segment of an illuminated surface that is contained in the image; identify a light fixture that is configured to direct light to the segment; and determine whether the image contains content indicating that the light fixture improperly aligned. For any image that indicating that the light fixture is improperly aligned, the system will output a signal indicating that the light fixture requires recalibration.

A wireless lighting control system is provided to create a lighting pattern by remotely controlling a plurality of lighting devices according to groups, thereby improving a lighting effect. The wireless lighting control system includes a first lighting device electrically connected with a first smart device to act as a master, and a plurality of second lighting devices electrically connected with a plurality of second smart devices to act as slaves, respectively. If a group for lighting control and control pattern information according to groups are selected from the first smart device, the first lighting device transmits the control pattern information according to the groups to the second lighting devices through a wireless communication scheme. At least one of lighting units of the second lighting devices and display units of the second smart devices is controlled based on the control pattern information according to the groups.

A smart light switch includes a control block and heat generating components such as a light actuator, a processor and memory, a data communications module, and an environmental sensor. The processor is operable to receive as an input a measured temperature value from the environmental sensor and a power consumption value from the of heat generating components. The processor is operable to select a temperature offset value from a dataset of temperature offset values that is stored in memory. Each temperature offset value stored in the dataset of temperature offset values is associated with a potential combination of power consumption inputs. The processor is further operable to determine a calibrated temperature value from the measured temperature value adjusted by the temperature offset values selected from the dataset of temperature offset values.

An autonomous vehicle is disclosed. The vehicle comprises a chassis, two or more drive wheels extending below the chassis, a drive motor housed within the chassis for driving the drive wheels, and a payload surface on top of the chassis for carrying a payload. An illumination system, for emitting light from at least one portion of the chassis, is mounted substantially around the entire perimeter of the chassis. The illumination system may be implemented using an array of light-emitting diodes (LEDs) that are arranged as segments. For example, there may be headlight segments on the front left and front right corners of the chassis.

A machine learning method executed by a computer, the method includes distributing a first learning model learned on the basis of a plurality of logs collected from a plurality of electronic devices to each of the plurality of electronic devices, the first learning model outputting operation content for operating an electronic device; when an operation different from an output result of the first learning model is performed by a user relative to a first electronic device among the plurality of electronic devices, estimating a similar log corresponding to a state of the learning model in which the different operation is performed from the plurality of logs; generating a second learning model on the basis of a log obtained by excluding a log of a second electronic device associated with the similar log from among the plurality of logs; and distributing the second learning model to the first electronic device.

A dynamic runway illumination system, including a light source having an addressable light beam direction, and a control unit configured to receive aircraft attitude information and the orientation of the runway selected for takeoff or landing, obtain horizontal and vertical axes, the horizontal axis being collinear with the takeoff or landing longitudinal direction, determine the actual and the reference aircraft trajectories, obtain the actual and the reference vertical approach angles, and the actual horizontal approach angle, and actuate onto the light source to perform an angular movement in the light beam direction of an absolute value of the actual vertical approach angle minus the absolute value of the reference vertical approach angle about the vertical axis, and an angular movement of an absolute value of the actual horizontal approach angle about the horizontal axis, to vertically and horizontally align the beam of the light source towards the runway direction.
