The system is configured to receive an indication that an unscheduled maintenance event for an aircraft is to be scheduled, and to determine, using the at least one processor, a maintenance schedule for completing the unscheduled maintenance event on the aircraft, a modified flight schedule for the aircraft, and a modified aircraft schedule for the aircraft based on the unscheduled maintenance event, an initial flight schedule, an initial aircraft schedule, and at least one selectable parameter indicative of user preferences to reduce a total cost of operating the at least one aircraft. The system is configured to provide at least one of the maintenance schedule, the modified flight schedule, and the modified aircraft schedule to the user interface.

Abstract: A computer includes a processor and a memory device. The computer is configured to a) receive decision-making criteria from at least one of at least a portion of a plurality of agents associated with a plurality of agent devices, the memory device, and a user, b) generate valid decision combinations using at least a portion of received decision-making criteria, c) transmit, to the plurality of agents, valid decision combinations, d) receive, from a deciding agent, a decision, and e) constrain, using the received decision, valid decision combinations.

The computer is configured to g) transmit a final decision set to the plurality of agents upon determining that no more decisions can be received. The final decision set represents a complete combination of decisions including at least a portion of received decisions.

Abstract: A method for identifying and analyzing data entities from (maintenance, repair, and overhaul (MRO)) data is provided. The method includes obtaining MRO data comprising unstructured text information. The method also includes performing named entity recognition on the MRO data to extract entities from the unstructured text information and label the entities with a tag. The method further includes analyzing the labeled entities via a heuristic to estimate an effectiveness of a fix for a specific issue or to estimate a reliability of a component.

Abstract: A computer-implemented method for estimating maintenance task durations is provided. The method is implemented by at least one computing system including at least one processor and at least one memory device coupled to the processor. The method includes receiving a query including a first query maintenance task and a plurality of query factors, and identifying an initial baseline task duration based at least in part on the first query maintenance task. The initial baseline task duration includes a plurality of baseline task factors. The method further includes identifying at least one adjustment factor based at least in part on the differences between the plurality of query factors and the plurality of baseline task factors, calculating a maintenance task duration estimate based at least in part on the initial baseline task duration and the adjustment factors, and planning execution of the first query maintenance task based on maintenance task duration estimate.

Abstract: A reinforced concrete wall system assembles rigid panels into two form walls in spaced apart relationship to securely hold poured concrete and reinforcing materials there between. The panels may include insulating foam. The panels are held securely side by side within a form wall by elongate connectors that have paired channels into which edges of the panels snugly fit. Each connector has brackets extending into the concrete space. Brackets are provided with perforations to receive tie rods. Each tie rod ties a bracket from one form wall to a bracket extending from the other form wall. This holds the space being filled with concrete together. The perforations are formed to resist releasing the tie rod once it has been inserted. Reinforcing steel is positioned by fastening to the tie rods.

Abstract: A radio receiver self test system (10) that can test a plurality of bands in duplex cellular phones and other duplex communication devices can be constructed so that it operates during idle time slots. The system can be configured to test the performance of the radio receiver at all ranges of signal levels and in all channels. The system can include a receiver (14) and a transmitter (12) coupled to an antenna (28) and an antenna/noise switch (16). The switch can have as an input, a noise source (18) such as a broadband or thermal noise source. A baseband upconverter/downconverter module (24) can include a processor that provides control signals (27 and 26) for controlling the level of the noise source and for controlling the switch. The system can further include linear amplifier (20) on a receive path and a power amplifier (22) on the transmit path.

Abstract: The current and voltage in an electrical system are monitored to detect an occurrence of an arc. The location of the arc is determined by propagating a pulse signal on the system in response to detection of the arc and timing the interval between reception of a portion of the signal reflected back from the location of the arc.

Abstract: The control system includes a schedule (54) which plots airspeed versus stabilizer angle for a trim condition. Following a pilot adjustment of the stabilizer angle to establish trim, the schedule (54) plots the trim airspeed to obtain a stabilizer angle value. A change in airspeed from trim is sensed by a sensor (52) and the schedule (54) plots the new airspeed on the same graph to obtain a new stabilizer angle value. The schedule (54) determines a change in stabilizer angle signal in the form of increments of movement of the stabilizer control actuator (28) to return the stabilizer (18) to a trim condition. A schedule (40) in the system also senses any change in the rate of change of altitude from trim and computes from this change a second signal in the form of increments of actuator movement. There is an algebraic summation of these two signals and a stabilizer angle feedback signal to produce a command signal.
