  • Patent number: 8890434
    Abstract: To control multiple electronic circuits organized in a series configuration, this document introduces a single-wire power, control, and feedback system. Specifically, individually controlled electronic circuits are arranged in a series configuration that is driven by a control unit located at the head of the series. The head-end control unit provides both electrical power and control signals down a single wire to drive all of the electronic circuits in the series in a manner that allows each electronic circuit to periodically draw power from the single wire and receive control information. Each electronic circuit in the series may communicate back to the head-end control unit by drawing power or not during a specified time slot.

  • Publication number: 20140265607
    Abstract: Electrical power is traditionally transmitted with high-voltage alternating current transmission lines. For some limited applications, high-voltage direct current is used to transmit electrical power since direct current transmission is much more efficient. However, due to the high costs of high-voltage alternating to high-voltage direct current conversion equipment, direct current transmission is rarely use. To provide direct current electrical transmission at a reduced cost, a loop-based direct current transmission system is disclosed. The loop-based direct current system operates by carrying direct current in a loop that coupled individual power consumer and power generating nodes. Each node can add voltage to or subtract voltage from the current loop.

  • Patent number: 8823281
    Abstract: To power and control multiple different electronic circuit nodes, this document introduces a single-wire multiple-circuit power and control system. Specifically, individually controlled circuit node units are arranged in a series configuration that is driven by a power and control unit located at the head of the series. Each of the individually controlled circuit node units may comprise more than one output circuit that is also individually controllable. The head-end power and control unit provides both electrical power and control signals down a single wire to drive all of the individual circuit node units in the series in a manner that allows each individual circuit node unit to be controlled individually or in assigned groups.

  • Patent number: 8716950
    Abstract: Data may be encoded onto a direct current power line by modulating the current on that direct current power line. One method of modulating the current is by placing an inductor on the power line and then using a controlled transistor that turns on and turns off. The inductor will ensure that current keeps flowing but the transistor will induce changes in the current pattern. The excess current from when transistor is turned off must be diverted. Furthermore, to create symmetrical current changes, the inductor should be reverse biased. Thus, a circuit is created that sinks the excess current from when the transistor is turned off and used to reverse bias the inductor.

  • Patent number: 8350497
    Abstract: An controlled LED lighting system that operates using a single conductor to power and control LED nodes is disclosed. The controlled LED lighting system modulates control data onto a nominally constant DC signal transmitted down a single conductor serial line. Nodes coupled the serial line draw power into a local capacitor and demodulate the data signal. Each node shunts the serial line when additional power is not required such that the data signal is received by every node on the serial line.
