Abstract: Elevator car door systems are provided. The systems include an elevator car having a car door and a movable car door coupling attached to the car and arranged to control operation of the car door. A mounting bracket is attached to the car, a first blade is attached to the mounting bracket, a second blade is attached to the mounting bracket, and a deterrent is attached to the mounting bracket. The first and second blades are operable a landing door coupling to operate the car door. A portion of the movable car door coupling is arranged to contact a ceiling of an elevator shaft during an overrun event when and move a part of the movable car door coupling relative to the car, and when the portion is not in contact with the ceiling, a biasing element urges the portion toward a normal position.

Abstract: Systems, methods and computer program products associated with a flight search engine for searching itineraries between an origin and a destination on a given date, according to a predefined display policy. Available routes may be filtered according to a first set of predefined criteria associated with the routes. The filtered available routes may be ranked according to a second set of predefined criteria. Itineraries may be constructed that are associated with the filtered available routes. The constructed itineraries may be filtered according to a third set of predefined criteria, and the filtered itineraries may be ranked according to a fourth set of predefined criteria. Historical booking data regarding previously booked itineraries for future travels may be received and analyzed, and may be taken into in the ranking of the filtered available routes and the filtered itineraries.

Abstract: A database system includes an original data source storing pieces of original data and a cache source storing pieces of cached data, each associated with an accuracy value. A method of processing queries in the system includes: for each randomly selected client query, retrieving a first piece of cached data matching the query, and retrieving a first piece of original data matching the query; for non-selected client queries, retrieving a second piece of cached data matching the query; evaluating the accuracy value of the second piece of cached data; if the accuracy value is below a given threshold, retrieving a second piece of original data matching the query, and updating the second piece of cached data by the second piece of original data; and adapting a probabilistic model based on the first piece of cached data and the first piece of original data using a machine learning algorithm.

Abstract: An aircraft having propulsion units for both conventional aircraft flight in the atmosphere and for high-altitude operation as a rocket. The aircraft is divided into a payload compartment and a compartment containing rocket propulsion unit propellant or fuel, and includes a long transverse wing with a small back-sweep to favor lift in the dense layers of the atmosphere and to thus make it possible to climb to high altitudes at a subsonic speed before using the rocket propulsion units. The return flight portion is performed by gliding or controlled as for a conventional aircraft.

Abstract: A method of integrating a High-level Language (HLL) function with a Hardware Description Language (HDL) representation of a circuit design can include identifying an attribute of the HDL representation of the circuit design that is resolved at compile time and determining a value for the attribute using an HLL function when compiling the HDL representation of the circuit design.

Abstract: A process for the production of a textile preform from interlaced filaments or sections of filaments, using a support (16) of a shape appropriate to the preform, on which are applied superposed layers of filaments or sections of filaments crossed in at least two directions, the layers being interconnected by filaments or sections of filaments which pass through them, and the filaments or sections being stretched or held on the support (16) by pins (18). The method further includes the step of reimplantation of the pins (18) by offsetting them, so as to avoid the concentration of defects inherent in the use of pins.
