Abstract: The present disclosure provides a load-bearing composite platform. The platform includes a core layer, first and second reinforcement layers, and a frame. The core layer includes a structural sublayer, a force distribution sublayer, and an abrasion prevention sublayer. The first reinforcement layer is adhered to the force distribution sublayer, and the second reinforcement layer is adhered to the structural sublayer. The second reinforcement layer is an inverse of the first reinforcement layer. The frame surrounds the first reinforcement layer, the second reinforcement layer, and the core layer.

Abstract: A method of fabricating a composite material, the method comprises the steps of a) providing a first layer of a fibre reinforced polymer, preferably a thermoset FRP, b) providing an array of thermoplastic islands across at least a proportion of a major surface of the first layer, c) providing a second layer of a fibre reinforced polymer, preferably a thermoset FRP, d) laying the second layer over at least some of the islands, and e) securing the first and second layers together. There is also disclosed a composite which comprises a first layer of a fibre reinforced polymer and a second layer of a fibre reinforced polymer, between which is an intervening layer comprising an array of thermoplastic islands.

Abstract: The present disclosure provides a filter cartridge for a facepiece respirator mask body. The filter cartridge includes a cover, a base, and a filter medium. The cover has a top surface, a cover sidewall, cover support elements, and an inhalation vent. The cover support elements extend downwardly from the top surface. The inhalation vent is located at least primarily in the cover sidewall. The base has a bottom surface, a base sidewall, base support elements, and an inhalation port. The base support elements extend upwardly from the bottom surface. The inhalation port is located in the bottom surface. The base and the cover collectively define an interior compartment. The filter medium is sandwiched between the base support elements and the cover support elements in a manner that divides the interior compartment into an upper chamber and a lower chamber.

Abstract: This disclosure provides a means to implement an autonomous guidance and flight control system on a partial authority aircraft. One embodiment of the disclosure includes receiving a control command result, filtering the control command result into a low frequency component and a high frequency component, directing the low frequency component to at least one trim servomechanism and directing the high frequency component to at least one stability augmentation stabilizer servomechanism, linking outputs from the trim servomechanism and the stability augmentation stabilizer servomechanism for actuating a pilot control configured to control rotors, and actuating at least one rotor. The low frequency component includes frequencies below a break frequency and the high frequency component includes frequencies above the break frequency. The break frequency is established by rate and position of the at least one servomechanism.

Abstract: An actively stabilized random number generator includes a random number generator and a feedback controller. The random number generator includes a chaotic physical circuit realizing an iterated function. The iterated function is configured to produce a trajectory of iterates and has an operating parameter β and a desired Markov operating point. A binary bit converter has a symbol function configured to produce binary symbols from the trajectory of iterates and a maximal kneading sequence. The feedback controller is configured to observe the maximal kneading sequence within the trajectory of iterates and adjust the operating parameter to the desired Markov operating point.
