Ultra Electronics | Date: 2015-10-28

A vector sensor for use in acoustic instruments is described. The vector sensor includes: a cylindrical bulkhead partition defining a plurality of channels extending longitudinally on a circumferential wall of the bulkhead partition between a first surface and a second surface of the bulkhead partition; first and second cylindrical piezoelectric transducing pieces affixed to the bulkhead partition and extending outwardly as cantilever beams and contained within respective pressure housing capsules. The sensor may include cylindrical foam end pieces fitted over the capsules and having corresponding channels in their outer surfaces that correspond to channels in the bulkhead partition, so as to allow wiring and strength members to pass through. The cylindrical piezoelectric transducing pieces may be formed from a piezoelectric cylindrical tube with a first electrode covering its inner surface and a second electrode on its outer surface. The second electrode may be formed from a plurality of electrically disconnected electrodes spaced around the tube and located towards a fixed end of the tube, leaving a portion of the outer surface near the free end of the tube uncovered.

A technique for operating a communication system includes determining whether a specific node of the communication system is a start node. In response to determining the specific node is the start node, transmission of a header over a communication link of the communication system for each frame period is initiated. The frame period also includes a plurality of address segments each of which has an associated data number. In response to determining the specific node is the start node, data numbers for address segments are compared with associated I/O module address settings to determine if a data number is equal to one of the associated I/O module address settings. In response to determining the data number is equal to one of the associated I/O module address settings, transmission of node configuration and data from an input module (included in associated I/O modules) or zeroes for an output module (included in the associated I/O modules) is initiated.

We describe apparatus or a programmable logic platform for controlling a complex system. There is a processor, a plurality of inputs coupled to the processor for providing input data from the complex system to the processor, a configuration database coupled to the processor wherein said configuration database defines a plurality of logical operations to be performed on said plurality of inputs, said plurality of functional operations comprising a plurality of logical operations, and a plurality of outputs for outputting data from the processor wherein the output data is determined based on the plurality of functional operations which have been performed on the input data and wherein the output data is used to control the complex system. The configuration database comprises a set of truth tables which define all the plurality of operations and each truth table has thirteen or fewer inputs whereby the operations are exhaustively testable.


An electro-thermal ice protection system includes a controller for managing and controlling electrical power generated to heat and de-ice surfaces, such as aircraft wings. The system is comprised of a number of power control modules (PCMs) and at least one master control unit (MCU). These elements can be stacked together and mounted into rack systems in order to provide scalable organized power distribution for a de-icing and ice protection system. The electro-thermal system can be used with a load leveling system and method capable of controlling switches such that it appears to a generator that the load is constant. Switches can be scheduled such that, ideally, the power load seen by the power source has emissions of no more than one PWM load superpositioned with zero or more constant, non-modulated loads.

A link assembly has a pair of mechanical links pivotally connected to rotate relative to one another about a pivot axis. A cable protector is provided as part of the link assembly. The cable protector has a cup with an end wall which defines a first end of a winding chamber, and an annular side wall which extends from the end wall and defines a side of the winding chamber. A lid defines a second end of the winding chamber opposite to the first end. The lid is coupled to the cup by a bearing so that the cup and lid can rotate with respect to each other. An opening is formed in the side wall of the cup and a slot is formed in the lid. The assembly is fitted with a cable having a length, a width, and a thickness, wherein the width of the cable is greater than its thickness. The cable has a first portion which extends along a first one of the links and passes into the side of the winding chamber through the opening in the side wall of the cup, a second portion which extends along a second one of the links and passes into the second end of the winding chamber through the slot in the lid, and a rolled portion in the winding chamber in which the cable is wound into a roll, the roll including an outer turn which leads to the first portion and an inner turn which is inside the outer turn and leads to the second portion.

A proximity sensor core for a proximity sensor. The core is made from a sheet of high permeability material that has a thickness that is less than a width and length of the sheet of material. The sheet of material is cut or shaped such that it has a head portion extending across a width of the sheet of material and the head has a first length. First and second leg portions extend for a second length from the same edge of the head portion. Each of the first and second leg portions extend across a portion of the width of the head portion. First and second foot portions extend for a third length from the respective first and second leg portions. The first and second foot portions have the same width as the respective leg portions In the basic design, the sheet of material comprises a first bend between each of the first and second foot portions and the respective first and second leg portions so that the first and second foot portions extend generally perpendicular to the respective first and second leg portions.

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.
