Abstract: A non-pneumatic tire having a block type reinforcement configuration includes: a tread unit that forms an outer portion of the tire and comes in contact with a road surface; a wheel unit that is connected to an axle; a spoke unit that is formed between the tread unit and the wheel unit; and a block type reinforcement unit that includes a block formed inside the tread unit in the circumferential direction of the tread unit, and a plurality of reinforcing members formed in the block to correspond to the shape of the block.

Abstract: The disclosed technology generally relates to a tire and more particularly to a non-pneumatic tire. The non-pneumatic tire that has maneuverability similar to a pneumatic tire even without using air pressure, and can support the load of a vehicle and can guide performance-oriented tire deformation behavior by using a meta structure. In an aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that serves as a structural support between the rim and the tread, in which the spoke unit is formed in a meta structure in which unit structures are repeated.

Abstract: The disclosed technology generally relates to a tire, and more particularly to a non-pneumatic tire that has handling performance similar to a pneumatic tire, supports the load of a vehicle and improves riding comfort by employing a parametric structure. In one aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that functions as a structural support between the rim and the tread, in which the spoke unit is formed by circularly arranging spokes. The spokes have a single closed-loop longitudinal cross-section circumscribed to the rim and around the center of the tire.

Abstract: The disclosed technology generally relates to tires, and more particularly to a method of and a smart tire system for evaluating a state of a tire, and providing an alarm, and to a smart tire configured for the method and the system. In one aspect, a method includes determining whether an abnormality or a problem exists in a state of a tire, by processing a tire state value from a TPMS sensor. Processing the tire state can be carried out by a sensor processor and/or a sensor information processor. The method additionally includes providing an alarm to a user, e.g., a driver. The method additionally includes verifying the determination of whether there is an abnormality or a problem. Thus, the disclosed method includes determining the state of a tire and providing an alarm, where the alarm has high reliability because it is generated based on examination of various parameters of the tire state, including, e.g., pressure, temperature and/or acceleration.

Abstract: Disclosed are a separator for a fuel cell that improves power characteristics of the fuel cell, and a fuel cell including the same. The separator includes a plurality of current-carrying units, and an insulating unit interposed between the current-carrying units, wherein each current-carrying unit includes a first polymer matrix in which carbon-based particles are dispersed, and the insulating unit includes a second polymer matrix in which insulating inorganic particles are dispersed. The separator for fuel cells includes an insulating unit that exhibits low gas permeability and superior electrical insulation property, and the current-carrying unit that exhibits superior strength characteristics and conductivity, thus increasing voltage generated per one cell and considerably increasing a power generated per a constant area, when applied to the fuel cells.
