  • Patent number: 11049386
    Abstract: A system for controlling delivery of power to a load includes a master control unit (MCU) and a synchronous solid-state relay. The MCU causes the relay to close when the voltage delivered to the relay is at a zero crossing state. The MCU causes the relay to open at either (a) the moment when the voltage delivered to the relay is at a zero crossing state, or (b) the moment that the current delivered to the relay is both over a threshold level and at a zero crossing state.

  • Patent number: 10783772
    Abstract: A system for delivering power to a load includes a master control unit (MCU) communicatively connected to a wireless network. A remote control circuit is electrically connected to the MCU. The remote control unit delivers a signal of a first voltage to the MCU when the remote control unit is not receiving a command signal from a remote controller, and deliver a signal of a second voltage to the MCU when the remote control unit is receiving a command signal from the remote controller. A relay unit is electrically connected to the load and to an output of the MCU. The MCU is programmed to selectively power the load by selectively passing control signals to the relay unit in response to commands received from the wireless network. When no signals are received from the wireless network, the remote control circuit may control the load, either directly or via the MCU.

  • Patent number: 10151787
    Abstract: An audible ground fault detection device may include: a pulse-width modulation (PWM) circuit to produce a pulse signal in response to an occurrence of a ground fault; and a buzzer circuit to emit an audible sound in response to receipt of the pulse signal. The device may include a power circuit configured to transfer power from the power line to the PWM circuit when a ground fault occurs in a load of the power line, and not to transfer the power from the power line to the PWM circuit when no ground fault occurs in any load of the power line. When the PWM circuit has no power, it will not produce the pulse signal. The power circuit may also provide DC power to the buzzer circuit in response to the occurrence of the ground fault. The buzzer circuit may include a passive buzzer.

  • Patent number: 9441271
    Abstract: This disclosure provides methods and compositions for amplification and sequencing of DNA templates, comprising at least two of: 2?-deoxyinosine-5? triphosphate, 5-propynyl-2?-deoxycytidine-5?-triphosphate, and 8-oxo-2?-deoxyguanosine-5?-triphosphate. Incorporation of these promoting nucleotides into amplification and sequencing reactions improves the amplification and sequencing of difficult-to-sequence DNA regions such as a GC rich regions or GT rich regions; repetitive sequences, including dinucleotide, trinucleotide, direct, inverted, Alu, poly A or poly T repeats; and hairpin or other secondary structures.

  • Publication number: 20070256147
    Abstract: The present invention relates to the use of split fluorescent proteins to determine whether promoters are coordinately active, whereby the transcriptional expression of incomplete portions of a fluorescent protein is controlled by different promoters and coordinate (not necessarily contemporaneous) promoter activity results in the reconstitution of a fluorescent protein. The present invention, in non-limiting embodiments, may be used to selectively label cells and cell structures in vivo and to demonstrate changes in promoter activity (for example, in developmental biology and drug discovery applications).
