Abstract: A statistical data collector gathers statistical data concerning the operation of at least one data terminal coupled to a host system by way of a data terminal controller. The data terminal controller controls access to the host by the data terminal. Each data terminal coupled to the data terminal controller includes at least one user definable function selector for selecting a previously defined data processing function. The data terminal controller further includes a statistical data collector, responsive to a selected data terminal user definable function selector, for gathering statistical data concerning the data processing function selected by the user definable function selector and operation of the data terminal.

Abstract: A system and method for controlling the dialing order of a plurality of call record lists by a predictive dialing system are disclosed. The system includes a flow controller and a list controller. The list controller receives a number of call records from a call list provider for establishing a plurality of call record lists. The flow controller links one or more call lists in a predetermined order to form one or more list flow campaigns which may be later edited or joined together by the flow controller. A predictive dialer receives the call lists according to the list flow campaign and dials telephone numbers in the order directed by the linked call record lists which form the flow campaign. Also disclosed is a method for linking call record lists.

Abstract: A device for quantitatively measuring the relative position and orientation of two bodies in the presence of metals via measuring the position and orientation of receiving antennae with respect to transmitting antennae utilizing direct current electromagnetic field signals is hereby disclosed. The transmitting and receiving components of the instant device consist of two or more separate transmitting antennae of known position and orientation with respect to each other. Each transmitting antenna is driven one at a time by a pulsed, direct current signal. The receiving antennae measure the values of transmitted direct current magnetic fields one dimension at a time and those of the Earth's magnetic field as well, one dimension at a time.

Abstract: A breakwater, or similar structure, comprising a core of rubble, and an armouring layer overlying said core, said armouring layer being composed of individual armour units of hexagonal outer cross-section arranged in a honeycomb array, each of said armour units having an elongated, concrete body with longitudinal through water-passage means so that the porosity of the exposed face of the armouring layer is solely determined by the ratio of the cross-sectional area of said water passage means to the cross-sectional area of the concrete body.
