Abstract: When looking at Hunminjeongeum, all words are written by organic combination of three writing elements. However, Hunminjeongeum became unsuitable for serial writing by borrowing consonants from a base. Considerable difficulties in the application to machine technology are made, and considerable limitations are caused in the expansion of the range. In order to alleviate the inconveniences, an applicant developed a character system called Kim Gwang alphabet. The designation of the three letters of the letter is started. On the other hand, only four simplest grid structures which can create more than eight shapes with only the own movement in a flat grid space. Four structures were grouped into three lattice logic structures and designated as consonants, vowels, and bases, respectively. In the present invention, a lattice logic structure designated as letters (consonants, vowels, and bases) was submitted as a claim.

Inventor: PARK JUNG DEUK
IPC: G06Q20/28
Filed: 2020-08-11
Abstract: The present invention relates to a fare payment system. According to the present invention, when a passenger uses a taxi transportation service, a fare is paid in advance rather than being paid later, such that the passenger can more efficiently manage money, and a route can be selected by inputting a departure and a destination in advance, such that a dispute between a taxi driver and the passenger is reduced. In addition, with respect to the risk during the alighting which is the most likely cause of an accident during driving of a taxi, the taxi can be used safer than an existing case of the alighting after paying a fare due to a moving flow with high concentration in which the alighting is performed at the time of arrival, and a taxi driver has a temporal benefit since a fare payment process is omitted after arriving at a destination, and reduces fatigue for the driving since the burden of safe alighting for a passenger is lowered. In addition, a rate based on past data is applied even though a taxi fare is paid in advance, a rate in accordance with characteristics of a map API is applied to minimize the loss of a taxi driver, and for the same reason, a part of additionally paid fares of a passenger is returned as mileage to prevent the loss of the passenger.

Inventor: KIM MIN SOO
IPC: B60H1/32
Filed: 2020-08-12
Abstract: In accordance with the present invention, a cooling/heating system for an electric vehicle supplies coolant, having absorbed waste heat of an electronic component, directly to a heater core during a heating operation, thereby enabling the waste heat of the electronic component to be directly used for heating, which can lead to an improvement in heating efficiency. Moreover, an internal heat exchanger is placed so as to exchange heat between a high-temperature/high-pressure refrigerant discharged from a compressor and coolant cooled by the heater core or a radiator, and can be used not only for a heating operation but also for a cooling operation, and, thus, heat exchange efficiency can be more improved, and also, a thermal connection between a refrigerant cycle and a coolant cycle can be more enhanced. In addition, since the internal heat exchanger can be used as a refrigerant condenser during a cooling operation, condensed heat of a refrigerant can be dispersed to the internal heat exchanger and an external heat exchanger, and, thus, the external heat exchanger can be made to be compact in size.
