Abstract: A vibration sensor includes a housing, a high G accelerometer installed in the housing to measure vibratory accelerations communicated to the housing; a low G accelerometer installed in the housing to measure vibratory accelerations communicated to the housing; and a processor installed within the housing to receive data from the high G accelerometer and the low G accelerometer. A method for using the vibration sensor includes employing the low G and the high G acceleration data. Another vibration sensor includes intrinsically safe buttons.

Abstract: A pipeline additive injection system including: an injection pump for injecting an amount of additive into a pipeline; a battery for powering the injection pump; system sensors to monitor system conditions; and a controller for retrieving system data from the system sensors and for controlling operation of the injection pump based on the system data to achieve additive injection compensation.

Abstract: A bag presenter for moving a bag from a bag supply toward a packaging machine filling station, the bag presenter comprising: a bag supply holding area, a gripper for holding a bag in the filling station and a bag handler for moving the bag from the holding area toward the gripper, the bag handler including a bag feeder and a bag conveyor, the bag feeder being operable to pull a bag from a bottom of the bag supply holding area and to pass the bag to the bag conveyor. The bag handler can include a bag opening mechanism and a means for maintaining the bag in an open configuration, once the bag has been opened. The bag presenter is useful for handling non-wicketed bags and can be used to convert a packaging machine from reliance on wicketed bags to use of non-wicketed bags.
