A wiper blade package has a mouth portion that is openable by being pressed in a lateral direction. The wiper blade package has a first panel, a second panel opposed to the first panel, and a pair of side panels. The first panel is bendable around a bend line extending in a longitudinal direction and has a lid flap at its end. The lid flap is foldable around the bend line and is pivotable around a hinge line intersecting the bend line. The second panel has an engagement flap at its end. The lid flap engages a free end of the engagement flap at its free end and thereby closes a receiving portion in which a wiper blade is received. The lid flap is pivoted from the engagement flap by pressing the side panels toward the receiving portion and thereby opens the receiving portion.

A remote control system and a remote control method of a construction machine for reducing a fatigue degree of an operator at the time when the operator controls driving of the construction machine depending on his/her body motion in the remote control system of the construction machine. For this, according to the present disclosure, a value acquired by compensating for a predetermined value εβ with respect to a finger bending angle βh for a palm is tracked by a bending angle βe of a bucket at the time of tracking the position of the bucket depending on hand motion of the operator to reduce a finger bending movement amount of the operator, thereby reducing fatigue. Further, the workspace of the operator is set to be smaller than points which are maximally movable in each of X, Y, and Z-axis directions at the time of setting the workspace of the operator, the workspace of WSh of the operator set to be small and a machine workspace WSe match each other, and the operator performs an operation in the workspace which is set to be small, thereby reducing the fatigue.

Disclosed is a method for controlling a wiper blade with heating elements embedded therein and coupled to a wiper arm of a vehicle to wipe a glass surface while moving together with the wiper arm. The method includes: detecting the operation or not of an engine of a vehicle; detecting the external temperature outside of the vehicle; and automatically supplying power to the heating elements based on the detected information on the operation of the engine and the temperature information. A wiper blade with heating elements capable of optimally maintaining a condition of the wiper blade even when the external temperature is low is also provided.
