摘要： A multimodal sensor includes first conductive electrodes that are arranged in parallel with one another, being spaced from one another by a certain distance, an insulating layer that is formed on the first conductive electrodes, second conductive electrodes that are formed on the insulating layer, crossing the first conductive electrodes, and are arranged in parallel with one another, being spaced from one another, and a controller that applies voltages to the first and second conductive electrodes. The controller detects capacitance formed between the first and second conductive electrodes, and senses an external temperature, intensity of a pressure or a position, to which a pressure is applied, in response to a variation of the capacitance.

摘要： An artificial skin culture container according to the present invention can solve the problems of the contraction of the dermal layer of artificial skin and the detachment thereof from the culture container, which result from an interaction between collagen and fibroblasts existing in the dermal layer of artificial skin during the production of the artificial skin, by using agar and hydrophobically modifying a portion of the agar. Therefore, the use of the culture container enables to stably culture artificial skin and produce artificial skin similar to the human skin. In addition, the artificial skin culture container of the present invention comprises agar, and thus a culture solution can be supplied through a side portion as well as a lower portion of the culture container, which allows to effectively culture artificial skin.

摘要： An application code obfuscating apparatus includes a secret code divider, a secret code caller, a code converter and an obfuscating part. The secret code divider is configured to divide an application code having a first type into a secret code and a normal code. The secret code caller generating part is configured to generate a secret code caller to call the secret code. The code converter is configured to convert the secret code having the first type to a second type. The obfuscating part is configured to generate a first table and a second table. The first table includes an obfuscated signature of the secret code and a first random vector. The second table includes an offset of the secret code which corresponds to the obfuscated signature of the secret code and a second random vector which is liked with the first random vector.

摘要： A user terminal includes a communication circuit, a certification circuit, an execution circuit, and a control circuit. The communication circuit receives a normal code of an application from an application providing server to install the application. The certification circuit receives a registration request message, which includes distinct information of a peripheral device, from the peripheral device storing a core code of the application, to certify the peripheral device, transmits a registration response message, which includes distinct information of the user terminal, to the peripheral device, and receives the core code of the application from the peripheral device. The execution circuit executes the application using the normal code and the core code. The control circuit restricts at least one of functions of the user terminal while the application is executed.
