Abstract: Systems and methods for determine a cost-improved set of control commands for an aircraft based at least in part on deterioration costs are provided. One example computing device is configured to iteratively: input a candidate set of control commands for the aircraft into the deterioration cost model; receive, as an output of the deterioration cost model, an estimated deterioration cost associated with the candidate set of control commands; input the estimated deterioration cost into a cost function to obtain a total estimated cost associated with the candidate set of control commands; and determine an improved set of control commands based at least in part on the total estimated cost and the cost function.

Abstract: Systems and methods for enhancing aircraft performance are provided. In one example, a method can include accessing an initial model that defines operating cost of an aircraft at a series of model operating states. The method also can include identifying one or more sample operating states for analyzing aircraft cost during flight. The method also can include receiving one or more real-time flight performance parameters indicative of aircraft operating cost while the aircraft is operating at the identified sample operating states. The method also can include generating an updated model that defines operating cost of the aircraft using the initial model as well as data defined by the real-time flight performance parameters. The method also can include determining an enhanced operating state based at least in part on the updated model and outputting the enhanced operating state for control of the aircraft.

Abstract: Systems and methods for stabilizing an aircraft in response to a yaw movement are provided. In one embodiment, a method includes detecting a yaw movement of the aircraft. The yaw movement can cause a front portion of the aircraft to move towards a first side of the aircraft. The method can further include, in response to the yaw movement, initiating a trim process resulting in a thrust differential. The trim process can include increasing thrust in one or more engines on the first side of the aircraft and decreasing thrust in one or more engines on a second side of the aircraft. The method can include controlling the trim process based at least in part on a detected yaw movement of the aircraft.

Abstract: Systems and methods for determining an operating state for an aircraft are provided. In one example, a method can include accessing, by one or more computing devices located on an aircraft, a database of precomputed operating parameters associated with aircraft trim determined in a priori process. The method can further include receiving a real time measurement of one or more dyanamic parameters associated with the aircraft. An aircraft trim parameter can be determined from the precomputed operating parameters independent of the real time measurements. The method can further include determining an enhanced operating state for the aircraft based at least in part on the aircraft trim parameter and the real time measurement of the one or more dynamic operating parameters.

Abstract: A light unit used in train tunnels is readily mountable and removable from a mounting bracket. The mounting bracket allows the battery backup system and light engine to be gravity mounted in manner that allows for quick and easy mounting and removal while also resisting vibrations and wind. A quick disconnect fitting can be used with the power cord to allow the units to be removed and replaced as needed. The light unit integrates the light engine with a battery backup system so that the entire light and battery unit is removed and replaced when necessary.

Abstract: A lockable storage case includes a top cover pivotably coupled to a bottom cover through a spine. The top cover includes loops or an upper lock receiving member and a lower lock receiving member defining a top cover lock insertion path. The bottom cover includes loops or an upper lock receiving member and a lower lock receiving member defining a bottom cover lock insertion path. The lower lock receiving members of both the top and bottom covers include hooks for receiving and maintaining a latch. When the top cover is closed on the bottom cover, the top and bottom cover insertion paths combine to form a combined lock insertion path. A lock for the storage case includes first and second catch mechanisms with first and second catches. To lock the storage case, the lock is inserted into the combined lock insertion path so that the catches on the lock mate with and are retained with the hooks in the top and bottom covers.

Abstract: Apparatus and methods for locking and unlocking a lockable container that has an internal locking mechanism are disclosed. The apparatus may include a main body including a channel for receiving the container. A magnetic field source coupled to the main body may emit a magnetic field for actuating a container lock catch mechanism disposed at least partially inside the container. The apparatus may include a channel blocker that may be positioned by actuating a channel lock to selectively prevent the magnetic field source from actuating the catch mechanism of a container lock. The channel lock may be coupled to a cam configured to position at least a portion of the channel blocker in the channel. In some embodiments, the apparatus may include a ramp retractor coupled to the channel blocker wherein the ramp retractor urges the channel blocker down through the channel by action of the magnetic field.
