Abstract: A system and a method for determining a sealant profile to be applied by a sealant applicator, the applicator being arranged to apply sealant to the surface of a component. The system includes an imager configured to generate measurement data representing the surface of the component and a data receiver. The data receiver is arranged to receive the generated measurement data and predetermined component-related data. The system also includes a processor arranged to analyse the received data and to generate, based on the analysis, a sealant profile for application to the component, and a data output arranged to output data representing the generated sealant profile to the sealant applicator.

Abstract: A fire sensor, fire sensing apparatus and a fire sensing system are disclosed. The fire sensor includes a layer of fibers arranged to cross one another at intersections. The fibers have an electromagnetic property which is changeable upon contact with fire and they are individually connectible to a detector of fire sensing apparatus to detect any change in the electromagnetic property. A change in electromagnetic property detected at any intersection of two fibers will indicate a fire at the location of that intersection. A movement of that location across the sensor will indicate the direction of travel of the fire. The sensing system is capable of sending alerts and extinguishing the fire.

Abstract: A cabin disinfection system for an aircraft, including: a sensing means (3, 11, 13) to sense the presence of personnel in one or more zones (16-19, 23-26, 28, 29, 30, 32), a predictive sensing means (3, 11, 13, 33) to sense the direction of motion of a person (31) and to predict whether that person will occupy a zone to be disinfected (18) during planned disinfection, one or more UVC radiation sources (4, 9) to disinfect the cabin, and a controller (33) to control operation of the UVC radiation sources (4, 9) dependent on sensing of personnel in that zone and the predictive sensing means (3, 11, 13, 33) predicting that a person (31) will occupy the zone (18) during the planned disinfection period.

Abstract: A system for monitoring health of crop to validate crop insurance claim is disclosed. The system includes monitoring sensors to capture images of the farm at a predefined time interval. The system includes a processing subsystem to process captured images of the farm using image pre-processing techniques, a meta data extraction subsystem to extract meta data corresponding to each crop of the farm from each of the one or more captured images, a decentralized classifier subsystem to store extracted meta data on a blockchain based storage platform, a decentralized classifier subsystem includes an image recognition classifier subsystem to perform time stamping on the extracted meta data in the blockchain based storage platform corresponding to each of the one or more captured images and a validation subsystem is to monitor health of each crop, by accessing time stamped meta data from the blockchain based storage platform, to validate crop insurance claim.

Abstract: A medium such as an ink or sealant for disclosing movement is provided. Also provided are a tape having the medium applied to it, and a method of disclosing movement of one or more elements. The medium is applicable as a settable liquid or paste to components, such as a nut and bolt or a flexible hydraulic hose, for which untightening or kinking movement is to be detected. The medium has an appearance, e.g. color, and contains distributed microspheres containing a second liquid having a different, usually much brighter, appearance. Once the medium is set, unwanted movement, such as untightening of the nut or kinking of the hose, will fracture the microspheres and the second liquid will be released to transform the appearance of the medium and alert an observer.
