Abstract: An embodiment relates to an artificial intelligence inference apparatus and method. The embodiment provides an artificial intelligence inference method, and may include converting an application based on a previously learned neural network into executable code in a high-level language independent of a learning framework, separating the executable code into General-Purpose Language (GPL) code and Domain-Specific Language (DSL) code depending on whether an acceleration operation is required, and generating target code optimized for hardware from the separated GPL code and DSL code.

Abstract: Provided is an operating method of a sensor node. The operating method of a sensor node includes receiving a sensing request, adjusting a sensing condition on the basis of the received sensing request, and sensing according to the adjusted sensing condition.

Abstract: In order to predict power consumption, previous measurements, which indicate the actual amount of power consumed in the past, and errors between previous estimates and the previous measurements, are used as first input data, and power consumption estimates for each prediction technique are simultaneously calculated by using the first input data in at least two prediction techniques. Next, the power consumption estimates calculated by each prediction technique and errors between the power consumption estimates and an actual measurement are used as second input data, and the final power consumption is predicted by making an additional power consumption prediction based on the second input data.

Abstract: In a light-installed area where a plurality of lights are installed, a light managing system senses a moving object that enters the light-installed area and predicts an predicted stop position of the moving object based on record information on a channel of movement corresponding to identification information on the moving object. The light managing system calculates a predicted channel of movement of the moving object based on the predicted stop position, and selects lights to be driven based on the calculated predicted channel of movement. The light managing system turns on the selected lights.

Abstract: Provided is an apparatus and method for tracking a position of a fixed node. The position tracking apparatus of the fixed node may include: an interface to extract, from a database in response to the occurrence of an event about tracking the position of the fixed node, packet data corresponding to a mobile node associated with the event; and a processor to analyze a received signal strength of the packet data and a position of the mobile node from the packet data, and to track the position of the fixed node using the analysis result.

Abstract: A data communication system is provided. The data communication system includes a main processor, and at least one sub-processor or at least one peripheral device connected with the main processor according to a serial peripheral interface (SPI) method and performing an operation corresponding to a command transferred from the main processor. The connection according to the SPI method is made by one or more bus lines including a master in slave out (MISO) line and master out slave in (MOSI) line, a slave select (SS) line, an interrupt line, and a clock transfer line.

Abstract: A method for effectively using power resource in a wireless mesh network is disclosed to select and change a level of a power saving mode according to terminal and network situations to increase the duration of the network's existence as well as improve the power consumption of each mesh terminal. After active mesh terminals that are to perform a data relay function and super-saving mesh terminals that are not to perform the data relay function are selected in consideration of a network topology at certain periods, the level of a power saving mode of the mesh terminals selected as the super-saving mesh terminals is higher than that of the mesh terminals selected as the active mesh terminals. And then, a routing path in a tree form is formed along the mesh terminals selected as the active mesh terminals to transmit data.
