    Abstract: Embodiments of the present invention relate to machines that perform in-system programming of programmable devices that are attached to assembled printed circuit boards. In accordance with one aspect, multiple nonvolatile devices may be programmed in a single session at their normal maximum programming speeds. Different nonvolatile devices on a board can receive different data. Data variables can be inserted so that not all boards receive identical data. A master controller sends image files and algorithm information to a subsidiary controller. The subsidiary controller executes a device algorithm, and an FPGA executes a bus algorithm. Embodiments of the present invention can be designed as stand-alone systems or to operate cooperatively with an automatic tester, so that testing and device programming can take place in a single operation using a single fixture to hold the circuit board.

    Abstract: A phase locked loop (PLL) circuit provides ac devices, such as power inverters and power measurement devices, with a reliable means for synchronizing to ac electrical systems. In an exemplary embodiment, the PLL circuit is configured for operation with single-phase electrical systems and offers substantial noise immunity by basing its locking operations on measured fundamental components, i.e., measured x-y phasors, of the electrical system voltage. Further, with its phasor-based locking operations and with its timer/counter-based operation, the PLL circuit can be implemented partly or wholly in digital processing logic.

    Abstract: A control circuit synchronizes an ac power inverter to the mains voltage of an electrical grid by matching the fundamental phasor components of the inverter's output voltage to the fundamental phasor components of the mains voltage. Once such matching meets an acceptable voltage error threshold, the control circuit initiates contactor closure, verifies contactor closure, and then initiates a changeover from voltage-mode control used in synchronization operations to a current-mode control of the inverter's output. The control circuit provides corresponding disconnection control when disconnection from the grid is desired, wherein the regulated power of the inverter is ramped down in controlled fashion until it reaches a lower threshold whereupon contactor opening is initiated. Once contactor opening is verified, regulation control reverts to stand-alone voltage mode control or to shut down, as needed or desired.

    Abstract: Through construction techniques, geometric design, and materials selection, audio entropy or randomness is introduced within an equipment structure or enclosure. This takes away the available sound energy by absorbing it or making it do work and dissipate before it can project audible sound outside the equipment structure or enclosure. “Damping” of the sound traveling through the equipment structure or enclosure is achieved by applying foam and/or fiberglass board/mat material to surfaces within the equipment structure or enclosure. By employing different material densities in the equipment structure or enclosure, sound levels at different frequencies can be diminished by not allowing them to pass through the structure or by greatly decreasing their amplitude. The semicircular sheathing within the equipment structure or enclosure that forms part of the airflow path refracts sound waves at different angles and does not make a good waveguide for transmitting the sound, which diminishes it.

    Abstract: A power inverter includes a regulator circuit that controls real and reactive power output by the inverter. The regulator measures real and reactive output power by calculating x-phasor components of the inverter's voltage and current output waveforms. Phasor calculation can be adapted for one or more pairs of single-phase voltages and currents. Determining the fundamental in-phase and quadrature components of output voltage and current reduces computational complexity by permitting the regulator to perform its power control processing largely in a dc signal domain, and enables separate real and reactive power control. The power inverter can include islanding detection logic, which exploits the ability to separately control reactive power. Exemplary islanding detection logic is based on determining whether changing the amount of reactive power output by the inverter induces an output frequency shift.
