Abstract: Charging management methods and systems for electric vehicle charging stations for use in a charging field with charging stations are provided. First charging operation with first power parameter is first performed for at least one first electric vehicle by at least one first charging station, wherein the first power parameter is a first output value. A server receives a charging request from second charging station or a mobile device through a network, and communicates with first charging station and second charging station to perform a load adjustment operation. Load adjustment operation is to adjust the first power parameter from the first output value to a lower power limit value of first charging station, and instruct second charging station to perform a second charging operation with a second power parameter for second electric vehicle, wherein the second power parameter is an upper power limit value of second charging station.

Abstract: Charging management methods and systems for electric vehicle charging stations for use in a charging field with charging stations are provided. First, a server instructs a first charging station to perform a first charging operation for a first electric vehicle via a network, wherein the server sets a first target power parameter value corresponding to the first charging operation, and the power output from the first charging station to the first electric vehicle in the first charging operation will not exceed the first target power parameter value. The server monitors a first power output value actually output from the first charging station to the first electric vehicle during the first charging operation, and determines whether to adjust the first target power parameter value of the first charging operation according to the first power output value and the first target power parameter value.

Abstract: A notification management method for reservation charging of electric vehicle charging station is provided. First, first electric vehicle is charged by an electric vehicle charging station set at a first geographic location. Then, a server is provided to record a reservation charging request for electric vehicle charging station, wherein reservation charging request is issued by a specific user corresponding to a second electric vehicle. The server receives a charging state of first electric vehicle from electric vehicle charging station via network and determines an estimated remaining charging time according to received charging state. The server receives a second geographic location of a mobile device corresponding to specific user via network.

Abstract: A projecting kaleidoscope includes a main body with a light source, an assembly of reflector/refractor optics and a projecting assembly intervening between the assembly of reflector/refractor optics and the main body. A diffuser of the projecting assembly may make the light beams homogeneous from the light source and improve the brightness quality of kaleidoscope patterns when they are projected outside of the projecting kaleidoscope.

Abstract: A method for controlling exposure of an image-capturing apparatus via a shutter by operating a switch associated with the shutter is disclosed. Firstly, a first triggering signal is asserted in response to an enabling operation on the switch to open the shutter. Then, a second triggering signal is asserted in response to the enabling operation on the switch to close the opened shutter. Preferably, the method further comprises a step of automatically closing the shutter when a predetermined time period is up since the first triggering signal has been asserted and before the second triggering signal is asserted.
