摘要： A logic circuit is driven by a single alternating voltage power supply so that the energy stored in parasitic capacitances can be mostly recovered, rather than dissipated, as in conventional logic designs. Successive stages of the logic circuit are of opposite conductivity types such that the successive stages are activated in alternate half cycles of the power supply without separate clock signals. Each stage of the logic circuit is precharged during a respective first half cycle of the power supply and is active in logical processing during a second half cycle. The half cycles are defined by the rising and falling edges of the power supply. The logic circuit resonates with an inductor coupled across the power supply but closely coupled to the logic circuit. This inductor and the method of charging and discharging the capacitors in the logic circuit serve to minimize the power dissipated during logical processing.
摘要翻译：逻辑电路由单个交流电压电源驱动，使得存储在寄生电容中的能量可以大部分被恢复，而不是耗散，如在常规逻辑设计中。逻辑电路的连续阶段具有相反的导电类型，使得连续级在电源的交替半周期中被激活，而没有单独的时钟信号。逻辑电路的每个级在电源的相应的第一半周期期间被预充电，并且在第二个半周期期间的逻辑处理中是有效的。半周期由电源的上升沿和下降沿决定。逻辑电路与耦合在电源上但紧密耦合到逻辑电路的电感谐振。该电感器和对逻辑电路中的电容器进行充电和放电的方法用于使逻辑处理期间的功耗最小化。

摘要： A system for enabling an apparatus having a feedback loop to resume steady state operation after feedback loop interruption without the occurrence of transients, the system generally comprising a first circuit for applying a state variable to a load and a second circuit for (i) controlling the first circuit, (ii) monitoring the state variable applied to the load, and (iii) controlling the first circuit to regulate the state variable applied to the load in accordance with a desired state variable. The first and second circuits and the load define a feedback loop. The second circuit further includes an input for receiving a control signal that has a first state that causes the second circuit to enable the first circuit to apply the state variable to the load and a second state that causes the second circuit to inhibit the first circuit from applying the state variable to the load thereby interrupting the feedback loop. The system further comprises a third circuit for storing the applied state variable and preventing decay of the stored state variable during interruption of the feedback loop. The feedback loop resumes operation and returns to a steady state operation in accordance with the stored state variable when the control signal returns to the first state thereby substantially preventing the occurrence of transients from being introduced into the system.

摘要： A system for and method of generating electromagnetic radiation in which the radiation has both a first and second utility. The electromagnetic radiation is modulated to produce electronically detectable variations to achieve the second utility, the variations not affecting the first utility. In one embodiment, the electromagnetic radiation is visible light. In this embodiment, the first utility is illumination and the second utility is the transmission of data. In another embodiment, the invention provides a lamp for generating visible light capable of providing illumination and transmitting data to a receiver. Any variations in the visible light resulting from the data transmission are imperceptible by a human eye regardless of the nature of the data being transmitted. In yet another embodiment, a power line carrier modem or wireless network may be used with the present invention to transmit information to the source.

摘要： A lamp ballast for energizing a lamp has short circuit protection. The lamp ballast contains a transformer that provides an output voltage to the lamp. The transformer has a primary winding, a secondary winding, and a third sense winding. The third sense winding has an output that provides an indication of transformer output voltage. A reference voltage circuit creates a reference voltage that provides an indication of a non-short circuited lamp ballast condition. A comparator compares the reference voltage and the output of the third sense winding to provide an indication if the third sense winding output is below the reference. This indicates if there is a short in the output of the lamp ballast. The secondary is wound on multiple sections of a bobbin with one section being a low voltage section. The sense winding is wound under the secondary in the bobbin secondary low voltage section. The ballast additionally has a track and hold circuit to prevent an indication of a short in the lamp voltage when the lamp voltage is dimmed with a dimming circuit. The ballast also has a preheat logic signal to prevent a short circuit indication during the preheat mode at startup.
