Abstract: Disclosed are an apparatus and method for constructing an intrusion detection system applied to CAN communication. The method for constructing an intrusion detection system applied to CAN communication may include extracting standard information by parsing an input file associated with CAN communication, setting a policy rule by applying at least one of a static ruleset and a custom ruleset using the extracted standard information, and creating a policy file to be applied to the intrusion detection system by packing the standard information and the policy rule.

Abstract: A fire grate assembly for stoker incinerators. A plurality of stationary and movable grate members are alternately arranged in the assembly. The assembly also has a preventing member, such as a liner plate, which is detachably mounted to an end of each of the movable grate members for preventing the stationary grate members and the movable grate members from directly contacting each other, while allowing the movable grate members to be linearly movable relative to the stationary grate members. The preventing member is replaceable and can have a countersunk hole, thus being adapted for bolting the end of each of the movable grate members.
