摘要:
A crash box of a bumper for a vehicle is provided in the bumper to absorb collision energy produced in a collision. The crash box is constructed such that upper and lower horizontal partitions and a plurality of vertical partitions are connected to each other to form a lattice structure having a plurality of hollow portions, and each of the vertical partitions is formed to be bent at a middle portion thereof. A vertical partition located at the outermost position of the hollow portions forming the lattice structure is bent towards the inside of the crash box, and a vertical partition provided in a middle portion of the crash box is bent to the outside or inside of the vehicle.

Provided is a wireless communication method in a wireless sensor network environment. The method overhears a packet transmitted from a source sensor node to a destination sink node and determines whether the destination sink node receives the packet. A transmission node selected by using local information among a plurality of neighboring sensor nodes transmits the overheard packet to the destination sink node when the packet is not received.

The apparatus includes: a control terminal for controlling the vehicle traveling; sensing devices that collect circumstance information of guidance areas desirous of guiding the vehicle by using the information technology infrastructures provided on the guidance areas; and a server device that recognizes a circumstance of the guidance areas to create a guidance route based on the collected circumstance information by the sensing device so that the control terminal controls the vehicle to travel along the guidance route.
摘要:
Conductive carbon nanotubes (CNTs) obtained by dotting carboxylated CNTs with metal nanocrystals by chemical functional groups, are described, as well as a method for fabricating a pattern or film of the conductive CNTs which involves repeatedly depositing conductive CNTs on a substrate to achieve high surface density. A biosensor is described, in which bioreceptors that bind to target biomolecules are selectively attached to conductive CNTs or a conductive CNT pattern or film. By use of the conductive biosensor, various target biomaterials that bind or react with the bioreceptors can be precisely measured directly or by electrochemical signals at large amounts in one step. Additionally, the biosensor can be used for an electrical detection method capable of providing precise measurement results even with a small amount of source material.
