Abstract: A method of preparing a carboxylic acid-modified nitrile-based copolymer latex is provided. The method of preparing a carboxylic acid-modified nitrile-based copolymer later includes emulsion-polymerizing a monomer mixture including a conjugated diene-based monomer, an ethylenically unsaturated nitrile-based monomer, and an ethylenically unsaturated acid monomer in the presence of a cross-linking agent including glyoxal.

Abstract: The disclosure is related to monitoring a legacy device using at least one smart device. A gateway of an automation system may monitor an operation status of a target legacy device located in a service area of an automation system using at least one of smart devices participating in the automation system. In order to monitor, a monitoring request may be received for monitoring the target legacy device from user equipment associated with a user. At least one of monitoring smart devices may be controlled for monitoring the target legacy device. Monitoring results may be received from the at least one of monitoring smart devices. The received monitoring results may be provided to the user through the user equipment using at least one of outputting monitoring smart devices.

Abstract: Described embodiments provide managing data collected from machine 2 machine (M2M) devices. A plurality of M2M devices may be grouped based on a common interest and the same group authorization key may be assigned to M2M devices in the same device group. A data collecting terminal having a group authorization key may be allowed to collect data in M2M devices when the M2M devices have the same group authorization key.
