摘要:
A multi-axis serially redundant, single channel, multi-path fly-by-wire control system comprising: serially redundant flight control computers in a single channel where only one “primary” flight control computer is active and controlling at any given time; a matrix of parallel flight control surface controllers including stabilizer motor control units (SMCU) and actuator electronics control modules (AECM) define multiple control paths within the single channel, each implemented with dissimilar hardware and which each control the movement of a distributed set of flight control surfaces on the aircraft in response to flight control surface commands of the primary flight control computer; and a set of (pilot and co-pilot) controls and aircraft surface/reference/navigation sensors and systems which provide input to a primary flight control computer and are used to generate the flight control surface commands to control the aircraft in flight in accordance with the control law algorithms implemented in the flight control computers.

A light filter or an array of filters can be either one or two dimensional. The filter or filters use multiple beam interference by varying an optical path length between semi-reflective surfaces. The optical path length between the semi-reflective surfaces is varied by changing a thickness of a polymer film in response to an electric field formed between two semi-transparent electrodes. The filter can be configured in either a transmissive or reflective mode.

An aircraft system for control of the application of power to a plurality of devices in the aircraft comprises a plurality of local control modules. Each local control module controls the application of the power to the group of at least one device. A central control system communicates with and controls the local control modules.

Embodiments according to the present invention provide an Impedance-based Arc-Fault Determination Device (IADD) and method that, when attached to an electrical node on the power system and through observations on voltage, current and phase shift with a step load change, determine the effective Thevenin equivalent circuit or Norton equivalent circuit at the point of test. The device and method determine the expected bolted fault current at the test location of interest, which enables calculation of incident energy and the assignment of a flash-hazard risk category.

According to an embodiment of the invention, a method of dynamically creating a network of a plurality of nodes operable to communicate with objects in operating sectors comprises establishing a first communication link between a first node and a second node of the plurality of nodes. The first communication link is established upon determining that the first communication link between the respective ones of the plurality of nodes would not cross an existing communication link in the network of the plurality of nodes between two of the plurality of nodes or upon determining that the first communication link would be shorter than any existing communication link in the network of the nodes between two of the plurality of nodes that the first communication link would cross. The first communication link has a first communicative line of sight between the first node and the second node.

An air compressor assembly includes a roll cage assembly which defines a protective volume within the air compressor assembly. The roll cage assembly supports an air storage tank and an air compressor, and at least substantially surrounds the air storage tank and the air compressor. The air compressor assembly includes a shroud mounted to the roll cage assembly. The shroud has a control panel portion including control and output components which are completely contained within the protected volume. The air compressor assembly further includes a handle. The handle is positioned along a vertical axis extending through the center of gravity of the air compressor assembly when the air compressor assembly is oriented to be carried by grasping the handle.

A tower device for supporting a crossbar over the roof of a vehicle includes a tower body, a clip retention mechanism and a clip selected to adapt to a particular vehicle profile. Various mechanisms may be used to secure the clip to the clip receiving mechanism. For example, a lock body may insert through coinciding apertures in a clip and clip receiver. A spring retainer may slide into slots or grooves in the lock body to prevent the lock body from disengaging. Other mechanism employ lock mounts that pivot to swing lock bodies through apertures in the clip and clip receiver.
