  • Publication number: 20240091730
    Abstract: The present invention relates to the stabilization of an effective ingredient by using a mineral material. In the present invention, the effective ingredient can be stably supported using the mineral material, and a microcapsule obtained by the manufacturing method according to the present invention, when discharged to nature, causes no environmental problems due to encapsulation ingredients thereof being the same as soil ingredients, and thus can avoid micro-plastic issues.

  • Patent number: 8861483
    Abstract: The present invention relates to a method and to a wireless personal area network (WPAN) device in which the device sets the beacon slot in the WPAN device and receives beacon slot information from neighbor devices, while setting the beacon table of the devices, to avoid the transmission time of the neighbor devices and the transmission time of the devices neighboring the neighbor devices in a WPAN. In the method, beacon message, including information about neighbors' transmission time and information about neighbors' neighbors' transmission time, is received from neighbor devices. The beacon message is combined, and the neighbors' transmission time information and the neighbors' neighbors' transmission time information are input into a beacon table. The neighbors' transmission time and the neighbors' neighbors' transmission time are input into a field for BTTSs to be avoided in the beacon table.

  • Patent number: 8654671
    Abstract: The present invention relates to a system and to a method for QoS (Quality of Service) support in a ubiquitous sensor network. The system for QoS support in a ubiquitous sensor network includes a mesh coordinator and nodes. The mesh coordinator organizes a super frame containing a dedicated QoS data transmission period, and synchronizes each of the nodes constituted into one network with the abovementioned super frame. The nodes create a beacon frame containing information on whether or not to set QoS, to broadcast the beacon frame in a dedicated beacon period of the super frame if QoS data transmission is needed, to create a QoS data frame with a set priority, and to transmit the QoS data frame to the dedicated QoS data transmission period of the super frame in the case of transmitting QoS data.

  • Patent number: 7995502
    Abstract: The present invention relates to a method of efficiently assigning addresses in a WPAN and a WPAN device. The address assignment method of the present invention is performed by a higher device. Address assignment information for determining an address to be assigned to a lower device, is managed. An address is assigned to a lower device that requests connection from the higher device based on the address assignment information. The address assignment information is updated to a address value as the address value is assigned, and the updated address assignment information is transmitted to lower devices. If an update of address assignment information is requested by the lower device that assigned an address value to a device lower thereto, the address assignment information is updated and the updated address assignment information is transmitted to lower devices.

  • Publication number: 20110075763
    Abstract: A local wireless signal transmitting/receiving apparatus and method using digital RF processing technology. When the local wireless signal transmitting/receiving apparatus generates a local wireless signal to be transmitted, spreads the frequency of the generated local wireless signal and thereby generates a baseband signal, the local wireless signal transmitting/receiving apparatus converts the baseband signal of the local wireless signal into phase information, converts the phase information into an RF signal by means of a polar modulator, and transmits the RF signal.

  • Publication number: 20100111048
    Abstract: The present invention relates to a method in which each device sets its own beacon slot by using beacon slot information of its neighbors and its neighbors' neighbors in a WPAN. In the method, beacon slot information of the neighbors and the neighbors' neighbors is received from neighbor devices. The beacon slots of the neighbors and the neighbors' neighbors are decided as beacon slots to avoid. The beacon slot of the WPAN device of the present invention is set among beacon slots of the beacon-only period, except for the beacon slots decided as beacon slots to avoid.
