Filed: 2001-11-23
Abstract: PURPOSE: Synchronous memory modules and systems are provided to realize a fully forward and backward compatible memory solution. CONSTITUTION: The gate of the N-FET is connect in parallel to a default driver(246) which is a connection to DIMM power supply Vcc through a resistor. The value of the resistor may be selected as appropriate for the switch specifications. The default driver preferably acts to maintain the switch in the "on" position such that termination of the clock is achieved through FET switch(245). If the resistive load of FET switch(245) is inadequate by itself for the desired termination, additional resistive load(s) can be incorporated in series with FET switch(245) between the differential clock line pair. The default state of switch(245) can be overridden by input(290) from memory system(10). Input(290) is connected to an unused pin of the DIMM, for example in a 184 pin DIMM, pins such as numbers.

Title: Media connection controlling method for home gateway device
Inventor: BAEK WON GWANG
IPC: H04L12/28
Filed: 2001-11-28
Abstract: PURPOSE: A media access control method of a home gateway device is provided to prevent data collision of each media by giving a priority in consideration of characteristics of each media and transferring data according to the priority. CONSTITUTION: A gateway device initializes terminal interface units of each media(S101). The gateway device recognizes of terminals of each media group constructed by a home network and broadcasts a priority inherently set for each terminal(S102). The gateway device receives media information from each terminal upon request(S103), and classifies media access priorities of terminals of each group(S104). The gateway device compares fairness so that every group can access a media at a proper rate(S105). If it is fair, the gateway device confirms media access priorities by groups and broadcast them to each terminal(S106). The priorities are updated after receiving media information after a certain period, and the updated priorities are transferred to each terminal(S107). Assigned the priorities, each terminal updates a media access priority(S201). When the gateway device requests transmission of media information, each terminal provides media state information as a basis for judging priority setup(S202). The gateway device updates a priority table by groups according to the determined priorities and refers the priority table for data transmission so that a data collision between terminals may not occur(S203). If there is a data to be transmitted(S204), each terminal transfers a data according to the media access priority of the group to which each terminal belongs, while there is no data transmission of a group with a higher priority(S205). The following process is performed in the same manner as the general Ethernet protocol(S206).

Patent KR-20010080652-A (KR)
IPC: C04B41/49
Filed: 1999-11-19
Abstract: This invention relates to a stable aqueous silane emulsion with constant particle size. The emulsion comprises a continuous water phase, a discontinuous silane phase, and an emulsifier system. The emulsifier system contains a primary surfactant and a cosurfactant. The primary surfactant functions to prevent coalescence of particles, by steric or ionic repulsion between particles. The cosurfactant prevents diffusion of the silane into the aqueous phase. The combination of primary surfactant and cosurfactant results in an adsorbed inner layer of cosurfactant between the silane and the outer layer of a mixture of both surfactants which contacts the water phase. The combination of primary surfactant and cosurfactant provides a barrier which prevents diffusion of silane into the water phase. A method for preparing the emulsion is also disclosed.
