Abstract: A hydraulic system of construction equipment having a float function is disclosed, which includes a hydraulic pump and a pilot pump supplying hydraulic fluid to drive a working device; a remote control valve outputting a pilot signal corresponding to an operation amount of an operation lever; a hydraulic cylinder connected to the hydraulic pump; a main control valve installed in a discharge flow path of the hydraulic pump to control a start, stop, and direction change of the hydraulic cylinder when a spool is shifted; a solenoid valve shifted to an opening position when a float function switch is turned on; and a two-stage port relief valve installed in a flow path between the main control valve and the hydraulic cylinder, and shifted to return the hydraulic fluid in a large chamber of the hydraulic cylinder to a hydraulic tank so that the working device moves down when the float function switch is turned on.

Abstract: An apparatus and method are disclosed for providing route guidance based on emotion. The apparatus includes an emotion information acquisition unit, a route information calculation unit, and a route guidance unit. The emotion information acquisition unit obtains information about a user's emotion using an emotion acquisition sensor. The route information calculation unit calculates emotion route information using the obtained emotion information and map information. The route guidance unit provides route guidance to the user using the calculated emotion route information.

Abstract: An apparatus and method for recognizing an emotion by use of a heart rate data is provided. The apparatus includes an input signal generation unit configured to receive a plurality of heart rate data, and generate input signals each having a sequence, a signal classification unit configured to classify the input signals into groups, and an emotion recognition unit configured to search for a group, to which the input signal generated by the input signal generation unit belongs, among the groups classified by the signal classification unit, and recognize a user emotion corresponding to the found group.

Abstract: An emotion-based vehicle service system for safe driving includes a multi-emotion sensor node configured to sense emotion information of a driver and passenger in a vehicle and condition information of the vehicle. The emotion-based vehicle service system further includes an emotion cognition processing apparatus configured to analyze sensing information provided from the multi-emotion sensor node to generate emotion cognition information, and a safe driving service apparatus configured to provide an emotion-based safe driving service depending on the emotion cognition information.

Abstract: The present invention relates to a sensing device of an emotion signal and a method thereof capable of recognizing and analyzing the change in emotion by collecting at least one of the bio signals and peripheral environmental signals, guiding the state of emotion to a user, and sharing emotion information with authorized persons and communicating it between them. The sensing device of the emotion signal according to the embodiment of the present invention includes a sensing signal processor that senses a plurality of bio signals and peripheral environment signals of a user; an emotion signal processor that generates emotion signals representing the emotional state of the user for each of the sensed bio signals and collects the emotion signals to generate an emotion index; and an emotion signal communication unit that optionally transmits the emotion signals and the emotion index to external authorized devices.
