摘要： We describe an ice protection system used for removing ice and/or other accretions from a structure. An actuator, coupled to a structure, is driven to generate vibrations in the structure. A controller drives the actuator using a signal that comprises a frequency chirp over a first period of time, and the controller controls the frequency chirp and the first period such that vibrations generated in the structure by the actuator propagate through the structure to coincide at a desired area of the structure remote from the actuator to remove ice and/or other accretions from the desired area of the structure.

摘要： A mechanical link includes a carrier for supporting a conductor within a mechanical link. The mechanical link may include a first arm and a second arm, the second arm being arranged for movement with respect to the first arm, and a flexible helical carrier for supporting a conductor, wherein the flexible helical carrier is received within the first and second arms. The carrier may be, or may include a generally helical member of a flexible material, the generally helical member comprising a continuous support portion having on both sides thereof upstanding wall portions.

摘要： The present invention relates to an apparatus and method for detecting the presence of water or ice on a structure, for example on the surface of an aircraft. One or more separate heaters are thermally coupled to a structure (for example on the back of wing leading edge skins). A controller applies power to the heaters to heat the different regions of the surface of the structure. The controller detects the presence of water or ice by comparing the power required to achieve the desired surface temperature, and a reference power, where the reference power is the power required to heat the surface of the structure to the same temperature if the structure were in a dry air environment (i.e. an environment devoid of water). If the power consumed by the heater is greater than the reference power, the presence of water or ice is inferred.

摘要： A filter for use with a brushless DC motor to filter a signal received from a floating terminal of the brushless DC motor, wherein the filter is configured such that a time delay introduced by the filter to the signal received from the floating terminal is equal to the time taken for a rotor of the motor to rotate through an angle equal to half of a commutation step of the motor.

摘要： The present invention generally relates to proximity sensor monitors and proximity monitor systems incorporating proximity sensor monitors. A proximity sensor monitor measures the impedance or other electrical characteristics of a proximity sensor component to determine the presence of a target. The proximity sensor monitor performs this measurement independently of a separate proximity sensor. The proximity sensor monitor is configured to compensate for differences between the measurement frequency of the proximity sensor monitor and the driving frequency of the proximity sensor.

摘要： An ice detection system, in particular a method, apparatus and controller for detecting icing conditions and the presence of ice formed on a structure. Also, a method, apparatus and controller to detect the prevailing environmental conditions to determine whether or not ice may form on a structure. Two heaters of an ice protection system (experiencing substantially the same environmental conditions) are driven to different temperatures (the first greater than or equal to 0° C., and the second less than 0° C.). A difference in the powers required to drive the two heaters indicates the prevailing environmental conditions. In another embodiment, a heater of an ice protection system is driven and the rate of change of surface temperature is measured over several periods. A substantial deviation from a rate of change of surface temperature, which indicates the presence of ice on the surface of the structure, is detected.

摘要： A method and system for detecting structural damage in a structure by detecting acoustic emissions from damage in a structure to obtain acoustic emission data, and processing the acoustic emission data in accordance with a model characterising acoustic paths. The model is built by inducing a plurality of types of acoustic emissions at each of a plurality of positions on a structure, the plurality of types of acoustic emissions corresponding to a respective plurality of types of structural damage. The acoustic emissions are detected using at least three sensors arranged on the structure, and the detected acoustic emissions are processed for each position to determine model data characterising effects on each type of acoustic emission from each position of acoustic paths between the positions and the sensors. The processed data is then stored as model data.

摘要： A cable (7) is routed between a pair of links (1, 2) that are pivotally connected about a lateral pivot axis (4). A wound section (8) is provided in the cable with the winding axis coincident with the pivot axis of the links. The wound section (8) may be preformed. A cable protector (10, 11) is provided each end of the wound section (8) along the pivot axis (4) so as to constrain the adjacent end of the wound section (8) to be keyed with it and the adjacent link.
