A gas turbine generating apparatus according to the present invention comprises a gas turbine capable of a high-speed operation, a permanent-magnet-type generator driven at a high speed by the gas turbine, an inverter device (5) for converting alternating-current power generated by the generator into commercial alternating-current power, and a system-interconnection device (9) for interconnecting output of the inverter device to a commercial AC power supply system (10). The system-interconnection device controls the inverter device based on voltage of the commercial AC power supply system as a criterion such that output current of the inverter device is in phase with the voltage or out of phase with the voltage by a constant phase difference. A control device (18) is provided for operating the permanent-magnet-type generator (4) as a motor at a time of starting the gas turbine, and supplying alternating-current power from a direct-current power supply through the inverter device or another inverter device in addition to the inverter device to the generator for increasing a rotational speed smoothly from zero. The control device detects output current of the inverter device and controls the inverter device to keep the output current constant.

An overmolded multi-port optical connection terminal for a fiber optic distribution cable includes a tether cable containing a plurality of optical fibers optically connected to a corresponding plurality of optical fibers terminated from the fiber optic distribution cable at a first end of the tether cable, an overmolded housing a the second end of the tether cable, at least one connector port, and plenum means for accommodating excess fiber length (EFL) caused by shrinkage of the tether cable and / or pistoning of the optical fibers of the tether cable during connector mating. In one embodiment, a centralized plenum means is defined by an internal cavity within the overmolded housing sufficient for accommodating the EFL without micro bending. In another embodiment, a distributed plenum means is defined by an oversized tubular portion of the tether cable having an inner diameter sufficient for accommodating the EFL without micro bending.

A wireless power adapter that mounts to the docking station port of a portable computer, such as a laptop computer, notebook computer or tablet computer. The wireless power adapter includes a docking port electrical connector selected to interface with the pre-existing docking port electrical connector on the portable computer. The adapter docking port electrical connector includes power pins to connect with the pre-existing power pins of the portable computer docking port electrical connector. The wireless power adapter may include an inductive secondary to wirelessly receive power from an inductive primary. The wireless power adapter may include a mechanical connector that interfaces with the pre-existing docking station mechanical connector on the portable computer.

A phased array antenna aperture able to form a structural, load bearing portion of another structure, for example, a portion of a mobile platform. The antenna aperture is formed with a plurality of radiating elements sandwiched between prepreg fabric plies to form independent wall sections having a plurality of electromagnetic radiating elements embedded therein. The wall sections are secured in a honeycomb arrangement to form an array of cells of radiating elements. The manufacturing methods described herein enable arrays of widely varying sizes and shapes to be created and used as structural, load bearing portions of a wing, fuselage, door panel or other area of a mobile platform. The antenna aperture is lightweight because it does not include the weight of parasitic support components typically required in the construction of phased array antenna apertures.

A modular blind transport system for a window blind application. The complete system may be assembled form a relatively small number of individual modules to obtain working systems for a very wide range of applications, including especially a category of counterbalanced blinds wherein a relatively small external input force may be used to raise or lower the blind, and / or to open or close the blind.

A conformal, load bearing, phased array antenna system having a plurality of adjacently positioned antenna aperture sections that collectively form a single, enlarged antenna aperture. The aperture sections are each formed by intersecting wall panels that form a honeycomb-like core having a plurality of electromagnetic radiating elements embedded in the wall panels that form the core. The aperture wall panels are assembled onto a single, multi-faceted back skin, bonded thereto, and then machined to produce a desired surface contour. A radome formed by a single piece of composite material is then bonded to the contoured surface. Antenna electronics printed wiring boards are also bonded to an opposite side of the back skin. The contour is selected to match a mold line of a surface into which the antenna system is installed. The antenna is able to form an integral, load bearing portion of the structure into which it is installed.
