Abstract: In an aspect, a braiding machine is provided, and has a set of spool shuttles that each dispense a strand of flexible material under tension. A strand retractor releasably retracts the strands from the spool shuttles. A plurality of shuttle stations at which the spool shuttles can be positioned are arranged in a circuit. At least one shuttle carriage, when driven, repeatedly selects an immediately previously unselected spool shuttle and moves the immediately previously unselected spool shuttle from an associated shuttle station to another shuttle station along the circuit spaced from the associated shuttle station by at least one shuttle station that is intermediate the associated shuttle station and the other shuttle station. At least one spool shuttle is parkable at the at least one shuttle station. A drive arrangement is coupled to the shuttle carriage to drive the shuttle carriage.

Abstract: A flight control system for an aircraft is disclosed. The flight control system includes one or more processors and a memory coupled to the processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the flight control system to receive as input a plurality of first operating parameters that each represent an operating condition of the aircraft. The flight control system is further caused to determine a drag coefficient and a lift coefficient based on the plurality of first operating parameters. The flight control system is also caused to determine an estimated dynamic pressure based on both the drag coefficient and the lift coefficient.

Abstract: A flight control system for an aircraft is disclosed and includes one or more processors and a memory coupled to the processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the flight control system to receive as input a measured angle of attack that is based on a raw angle of attack and an estimated angle of attack based on a total pressure. The flight control system is further caused to compare the measured angle of attack with the estimated angle of attack to determine an error. In response to determining that the error between the measured angle of attack and the estimated angle of attack exceeds a threshold value, the flight control system determines the presence of a fault with an angle of attack value.

Abstract: A flight control system for an aircraft is disclosed, where the flight control system detects a first common mode pneumatic event. The flight control system includes one or more processors and a memory coupled to the processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the flight control system to receive as input a measured dynamic pressure and an estimated angle of attack. The flight control system is further caused to determine a rate of change of the measured dynamic pressure and compare the rate of change of the measured dynamic pressure with a dynamic pressure threshold value. The flight control system is further caused to determine a rate of change of the estimated angle of attack and compare the rate of change of the estimated angle of attack with a threshold angle of attack.

Abstract: The present invention provides apparatus and a method for use in weaving elongate members together and most typically elongate members in the form of hair attached to the head of a person or a toy doll. The elongate members are provided in groups and the groups pass through passages in a weaving mechanism and along guide tubes which are located to the opposing side of the weaving mechanism from the item to which at least some of the elongate members are attached. Typically, relative movement of the weaving mechanism along the elongate members and the operation of the weaving mechanism cause the weave, such as in the form of plaiting, braiding or cornrowing to be formed.

Abstract: There is provided an article being moveable between a first position and a second position and biased to the second position. The article is retained in the first position by retaining means until a predetermined condition is met, wherein when that predetermined condition is met, biasing means exert a biasing force to move the article from the first position to the second position. The predetermined condition is met when at least one formation, located on at least one face of the article, is moved from a first position to a second position, thereby releasing the retaining means and permitting movement of the article from the first position to the second position. Also provided is a group of at least two articles provided to interact with one another, with one article meeting the predetermined condition for moving the other from the first position to the second position.
