Abstract:
Disclosed is an RFID apparatus. The apparatus of the present invention comprises: a first set of antennas for a recording/reading operation on information in an RFID tag; a second set of antennas for the recording/reading operation on the information of the RFID tag, wherein the second set of antennas are installed so as to be spaced apart from the first set of antennas along the forward conveying direction of a conveyor; and a controller for controlling the operations of the first set of antennas and the second set of antennas in accordance with an RFID profile. The first set of antennas comprises at least two antennas arranged opposite each other in a vertical direction on the conveyor. The second set of antennas includes at least two antennas arranged opposite each other in a vertical direction on the conveyor.
Abstract:
The present invention relates to an apparatus for automatically controlling illumination, which transmits a dimming signal on the basis of the zero-crossing of AC power using an electronic switch for controlling illumination. The apparatus for automatically controlling the illumination of LED lighting according to one embodiment of the present invention comprises: a dimming control electronic switch which cuts off the supply of the AC power for a preset period of time on the basis of the zero-crossing of the AC power, when a switch operation by a user is sensed during the supply of AC power to an LED lamp; and an LED lamp control device which senses the supply of the AC power and the cutoff of the AC power so as to control the illumination of the LED lamp.
Abstract:
Disclosed is a duty cycle correction apparatus. The apparatus of the present invention adjusts signal widths of an input signal, averages the widths of the signal, and inverts the signal, then averages the widths of the inverted signal, compares the two averaged signals, and outputs the difference between the two averaged signals.
Abstract:
The present invention relates to an automatic illumination control device capable of controlling the LED lighting in a sensory manner by using an illumination-controlling electronic switch for adjusting the illumination of an LED lamp. According to the present invention, the automatic illumination control device of the LED lighting device comprises: a dimming-controlling electronic switch which outputs a pattern signal for supplying or blocking AC input power supplied to an LED lamp; and an LED lamp control device which interprets said pattern signal, and controls the illumination of the LED lamp according to the interpreted pattern signal.
Abstract:
An electric vehicle charges a battery through an electric vehicle power supply apparatus, and periodically checks a current charged state of the battery during a charging operation. During the charging operation, the electric vehicle transmits to a user terminal a first charging information notifying message including information on a current charged state of the battery. When the completion of charging of the battery is detected, the electric vehicle transmits to the user terminal a second charging information notifying message providing notification of the completion of charging of the battery.
Abstract:
An electric vehicle comprising a battery checks through an electric vehicle power supply device whether the battery can be charged. The electric vehicle charges the battery through the electric vehicle power supply device if the battery can be charged through the electric vehicle power supply device. The electric vehicle transmits to a user terminal device a charge information notification message, which indicates a failure to begin charging, when the battery cannot be charged through the electric vehicle power supply device.
Abstract:
According to the present invention, a method for controlling a load comprises the steps of: receiving, from a host device, a load control message for controlling at least one or more loads; transmitting a load control command to at least one or more load devices, on the basis of at least one of said load control message, state information of the load devices, and preset load control condition; and transmitting, to said host device or an external device, a response message that includes information indicative of a load control state in response to said load control message. Thus, according to the present invention, the method for controlling the load allows: a user to intuitively recognize economical gains about the load control command such that the efficiency of a load control system is increased; and the utility to notify the load control with respect to the commercial aspects, thereby inducing user participation for the load control command more easily.
Abstract:
A method for load control in a load control device is disclosed. According to the method for load control of the present invention, a user intuitively recognizes the economic gain of a load control command in order to consider the efficiency of the load control system.
Abstract:
An electric vehicle comprising a battery charges the battery through an electric vehicle power supply device, and transmits to a user terminal device a first charging information notification message, which includes information on a current charging status of the battery. The electric vehicle detects an interruption to the charging of the battery on the basis of the current charging status of the battery, and checks the cause for the interruption to the charging of the battery. When the interruption to the charging of the battery is detected, the electric vehicle transmits to the user terminal device a second charging information notification message, comprising information on battery charging status that indicates the interruption to the charging of the battery and charging error information that indicates the cause of the interruption to the charging of the battery.
Abstract:
A device for controlling communication with a vehicle, which is embedded inside an electric vehicle, collects battery information with respect to a battery of the electric vehicle, and receives power policy information from a power supply facility. The device for controlling communication decides available options for charging the battery of the electric vehicle on the basis of the battery information and the power policy information. The device for controlling communication controls the charging of the battery of the electric vehicle according to the available options.
