Abstract: Disclosed is an interface system including a first neuron cluster that outputs a first neuron signal including a first neuron request and first neuron data by performing a first arithmetic operation, and a first interface circuit that stores the first neuron data and outputs a first response, in response to the first neuron request. The first neuron cluster outputs a second neuron signal including a second neuron request and second neuron data by performing a second arithmetic operation, in response to the first response. Before the first data is transmitted to a second neuron cluster different from the first neuron cluster, the first interface circuit outputs the first response in response to a fact that the first neuron data is stored.

Abstract: Disclosed are a fingerprint forgery detection device and a method of operating the same. The fingerprint forgery detection device includes a memory that stores a first feature signal including biological channel feature information of a user, a transmitter including at least one transmission electrode for transmitting a pulse signal to the user, a receiver including at least one reception electrode for receiving a biological channel response signal in response to the transmitted pulse signal, and a signal processor for processing the biological channel response signal to detect whether a fingerprint is forged, and at least one processor that controls the memory, the transmitter, and the receiver.

Abstract: A stator for an AFPM motor and a method of manufacturing the stator are disclosed. The stator includes a stator housing having radially extending blades, a stacked core, and a winding core wound along an outer circumferential surface of the stacked core. The stacked core is coupled to the plurality of blades. The stator has an outer housing coupled to an outer circumferential surface of the stator housing to seal an inner space of the stator housing and has outer ring covers coupled to opposite side surfaces of the stator housing, respectively.

Abstract: Disclosed is an amplification circuit, which includes a first amplifier that receives an external signal and performs first band pass filtering on the external signal to output a first filter signal, and a second amplifier that receives the first filter signal and performs second band pass filtering on the first filter signal to output a second filter signal, and a frequency pass bandwidth of the second band pass filtering is narrower than a frequency pass bandwidth of the first band pass filtering.

Abstract: A hybrid communication device, an operation method thereof, and a communication system including the same are provided. The hybrid communication device includes a contact unit that includes an antenna for receiving a first communication signal and an electrode for receiving a second signal, a switch controller that includes a first switch and a second switch and controls the first switch and the second switch based on a change in capacitance of the electrode, and a signal processing unit that receives at least one of the first communication signal and the second communication signal from the contact unit via the first switch and processes the received signal. The first switch is connected to the contact unit, and the signal processing unit is connected to the first switch.

Abstract: A floor mat including a carpet portion, one or more hook-and-loop fastener portions, an anti-slip portion, and an edge portion is provided. The carpet portion is disposed on a top surface. The one or more hook-and-loop fastener portions are disposed on a bottom surface, each of which being corresponds to a counter fastener portion installed on a floor. The anti-slip portion is disposed on the bottom surface, comprising a plurality of bumps protruding downward from the bottom surface. The edge portion surrounds and secures the top and bottom surface. The bumps are disposed in a predetermined density and pattern. The carpet portion may comprise durable fabric.

Abstract: A method of detecting a crack in a disc loaded on a disc drive and a method of automatically lowering a target speed in response to the detection of a crack in order to stabilize the disc drive. According to the methods, it is automatically determined whether a disc loaded on a disc drive has a crack in a specific mode, and a target speed is automatically changed into a low speed when it is determined that the disc has a crack. Therefore, the crack state of the disc is exactly checked during action of the disc drive, the percentage of error occurrence is decreased, and the probability of damage to the disc is reduced.

Abstract: Provided are a method and apparatus for providing and using content advisory (CA) information on Internet contents. A method of providing CA information by using a CA information server, includes receiving a request for the CA information on a content, from an Internet Protocol television (IPTV); searching for CA information on the content; and transmitting the found CA information to the IPTV. A method of using CA information when an IPTV reproduces a content not having the CA information, according to the present invention, includes transmitting a request for CA information, to a CA information server; receiving the CA information from the CA information server; analyzing the CA information; and applying the CA information.
