Abstract: A method and system for secured data communication where a plurality of users communicate through ports on a common communication channel. The users communicate by transmitting and receiving data packets. The data packets are transmitted with a variety of fields of information, including but not limited to a destination address, a source address and a source port ID. A security module is connected to the common communication channel and reads the data packet contents and the source port ID. The security module then checks this information to see if the data packet is eligible to be transmitted on the common communication channel and to check which ports are eligible to receive the data packet. If the data packet is not eligible to be transmitted on the common communication channel, the security module destroys the data packet. The security module also sends out a security message on a security channel indicating which ports are eligible to receive the data packet.

Abstract: The present invention has an arrangement that two ends of a rectangular metal plate are turned up and the two ends are caused to approach at the central portion of the rectangular metal plate while maintaining a small gap so that a flat-pipe-type connection plate is formed, and the ends of elongated metal plates are slightly bent downwards to form insertion members which are inserted into the upper central gap of the connection plate from two directions.The thus-arranged structure causes rain in the connection portion to enter through the gap between the ends of the elongated plates corresponding to the upper central gap of the connection plate. Rain allowed to enter flows downwards through the flat-pipe-like connection plate. Since the lower portion of the connection plate is positioned upper than the lower elongated plate, rain is discharged onto the lower following elongated plate.

Abstract: A marking device with a reciprocating needle. The needle is attached to an armature which reciprocates in a slot in a housing by a crank which is rotated by a motor in the housing. Vibration of the motor and tolerances between the armature and track cause unwanted movements of the needle in a plane perpendicular to the reciprocating motion. Guide bars and bushings connect the armature to the track. Tolerances between the guide bars and bushings are less than tolerances between the armature and track. An armature bracket is detachably connected to the housing in order to partially or fully close off an open end of the track after the armature has been inserted into the track. Guide bars and bushings then connect the armature and the armature bracket. The motor is supported on only one end by bolts extending from a mounting wall inside the housing. A damping plate is positioned between the motor and the mounting wall, and a damping ring is positioned between, and contacts, the damping ring and the housing.
