摘要： In a computer controller for fuel dispensing including a base member, a pulser member supported by the base member and capable of detecting the various increments of fuel quantity being dispensed in addition to deductions therefrom, the signals from the pulser being transmitted to a computer, the computer processing the signals for delivery to a display assembly, and disclosure of the processed information upon liquid crystal displays readily available for view by the customer; a junction box mounted upon the base member, the junction box being completely sealed for exhibiting explosion proof attributes to prevent ignition from sparking of the associated electrical wires or thermal heating of associated electrical components, contained therein and precluding an incident ignition of the external ambient fuel vapors, a computer housing mounted upon the junction box and incorporating the various intrinsically safe circuit boards comprising the computer, and the display assemblies either connecting upon the computer housing or being portable in installation for suspension upon the front of the existing dispenser in converting it from the mechanical actuation type to an electronic computer controlled fuel dispenser.

摘要： Improvements in the detection of TWACS outbound message signals. A first improvement involves matching some (or all) of the intermediate points in an outbound preamble occurring between bits of the preamble currently being detected. This reduces the possibility of a false synchronization and therefore decreases the probability of missing outbound message signals. A second improvement is to require some or all of the known preamble bits to exceed a predetermined threshold where both the thresh-old and which bits are adjustable. An additional approach is using 4-8 additional buffers in a transponder to detect preamble patterns in the outbound message. Each half cycle of the outbound message waveform requires entering a bit only into the buffers active for the particular frame of reference in which the message is being transmitted, since only buffers for that frame of reference are employed. The process continues until all bits specified to be sent, based on the length of the outbound message, are extracted. A CRC is then performed for the message. Using this method eliminates the problem of inbound messages being detected as outbound messages, and the resulting “blindness” of the transponder. It further makes the transponders less sensitive to noise which currently causes the transponder to detect a preamble when there is none, resulting in a valid outbound message being missed.

摘要： A method for concurrently communicating over each phase of an electrical power distribution network (N). A first outbound signal (SO1) is transmitted over one phase (AN-A) of a bus (S) by an outbound modulation unit. The unit is released as soon as the first outbound signal (SO1) is transmitted so the unit can transmit a second outbound signal (SO2) over a second phase (BN-B or CN-C) of the bus. The second outbound signal is transmitted concurrently with an inbound signal (IB1) sent in response to the first outbound signal (SO1). The unit is again released, as soon as the second outbound signal (SO2) is transmitted, so the unit can transmit a third outbound signal (SO3) over the third phase (BN-B or CN-C) of the bus. This third outbound signal is transmitted concurrently with a second inbound signal (IB2) sent in response to the second outbound signal (SO2). The method allows concurrent communications over all three phases of the network (N).
摘要翻译： 一种用于在配电网络（N）的每个相位上同时通信的方法。 通过出站调制单元在总线（S）的一相（AN-A）上发送第一出站信号（SO 1）。 一旦发送第一个出站信号（SO 1），该单元就被释放，因此该单元可以在总线的第二相（BN-B或CN-C）上发送第二出站信号（SO 2）。 第二出站信号与响应于第一出站信号（SO 1）发送的入站信号（IB1）同时发送。 一旦第二出站信号（SO 2）被发送，该单元再次被释放，因此该单元可以在总线的第三阶段（BN-B或CN-C）上发送第三出站信号（SO 3）。 该第三出站信号与响应于第二出站信号（SO 2）发送的第二入站信号（IB2）同时发送。 该方法允许网络（N）的所有三个阶段的并发通信。
