An industrial or manufacturing communication system and devices typically used in an industrial environment including several industrial devices such as work stations wherein a work station power distribution line runs along side the work flow or conveyor line, with individual data units connected between the individual work stations and the power distribution line, and further includes a similar connection by a data unit between a process controller and the power distribution line, wherein a selective flow of data is provided between and/or among the individual work stations and/or a workstation and the process controller. Further embodiments include the powering of the data units from power derived from the power distribution line(s), and integration and/or embedding some or all of the communications elements of the present invention into the structure, e.g. circuit boards, of the workstations and other devices connected to primary and/or secondary power lines.

The apparatus according to the present invention provides an arcade machine receiving a coin from each player along one or more coin paths which determine the coin path and thus the outcome of the player's participation. The coins are introduced tangentially from one of several locations to the outer edge of a funnel-like bowl with a lowered center exit, and proceed generally around the bowl and exits to a generally planar table below the exit, which includes revolving blades to stir the coins in the table. As the coins accumulate or are urged by the blades, and eventually fall from the outer perimeter of the table to coin output drawers or openings, where the coins may be withdrawn by the player as winnings.

A transceiver device for coupling between a power line and a network interface unit includes a power line modem for transmitting and receiving data between the power line and the network interface unit and a power circuit coupled to the power line modem that is adapted to deliver a DC power signal to the network interface unit. The power circuit includes a discovery circuit adapted to determine the type of network interface unit that is attached. A load path control circuit switches the DC power signal between a PHY interface and a connector interface of the power line modem based on the determined type.

A circuit and system having an inductive data link from one or more user-side phases to a plurality of line-side phases by individual data transformers having a winding coupled to the particular phase by a high-permeability ferrite material. The resulting connection across the primary (or primaries) and secondary (or secondaries) selectively provides and efficient coupling of data in a multi-phase environment including step-down distribution transformers and “Δ”-to-“Y” configured circuits while maintaining isolation at the power line frequency. Further embodiments include transfer to selected phases or single-phase applications, and selective signal-pass or -reject filtering.

A data transmission system forming a network including transmission line sections comprising traditional infrastructure such as AC power line (mains), twisted-pair (e. g. CAT-5) and coaxial cable wiring interconnected with a novel adapter to form a data system also providing data transfer over an extended length and diversity of connected equipment. Further combined with a data bridge connected to conventional format data (e. g. Ethernet) and to the traditional data infrastructure wiring, the novel adapter permits connection to any 2 of twisted pair/multi-pair, coaxial and power mains for data flow therebetween.

A power mains distribution panel including a data signal coupler providing a data path across multiple circuits therein. The power mains distribution or breaker panel provides mains power distribution from multiple non-neutral (i. e. having a voltage and providing a flow of current relative to each other or a common or neutral wire or virtual point, also called ‘hot’) mains circuits of a single or multiple phase for distribution within the distribution or breaker panel to branch circuits which in turn have a data path therebetween according to the present invention. Also described is a particular data signal coupler which may be used in the embodiments of the power mains distribution panels according to the present invention.
