Abstract: A system may include an interface connected to at least one of a plurality of nodes via non-power line wiring not used for Ethernet communications. The system may also include a controller carrying the interface, and the controller uses a broadband over power line protocol to provide Ethernet data communications over the non-power line wiring amongst each of the plurality of nodes.

Abstract: Systems, methods, and devices may provide for communications at a fueling facility. In one general aspect, a system, device, or technique for a fuel dispenser may include the ability to receive a signal including information in a first communication protocol and information in a second communication protocol, separate the signal into the first communication protocol and the second communication protocol, and process the signals in the first and second communication protocols.

Abstract: An apparatus which is a single portable device for scanning and downloading data. The apparatus employs a laser within an optical scanner to accomplish both scanning and downloading functions. In addition to the optical scanner, the apparatus employs control and communication circuitry for switching from scanning to downloading and for modulating an outgoing laser beam during downloading. A modulating material, such as a liquid crystal display or electrochromic lens, is excited to modulate the outgoing laser beam passing through it. The optical scanner also includes a motor-driven mirrored spinner which may be stopped to accomplish a high rate of data transfer during downloading using a highly directional beam.

Abstract: An apparatus is disclosed for scanning a bar code label on purchased merchandise items, including a support member having a first conveyor belt mounted above a second conveyor belt, and a digitizer panel oriented in a downward direction positioned therebetween. The digitizer panel will track the X and Y locations of the merchandise items as they move down the face of the panel. A plurality of optical canners are positioned above and below the digitizer panel for scanning a bar code label on a merchandise item moving across the digitizer. Processing means coupled to the digitizer and each of the scanners will detect the bar code label being read by each scanner when more than one merchandise item is located on the digitizer.

Abstract: An apparatus for controlling the charging voltage applied to a battery cell includes a printed circuit board having a flexible portion comprising a heat sensitive material which is wrapped around the battery cell for sensing the temperature of the battery cell during charging of the battery cell. Circuit means connected to said temperature battery apparatus disables the charging voltage upon the temperature of the battery cell reaching a predetermined level and generates a trickle charge in response to the disabling of the charging voltage.
