| 20120085868 | AIRCRAFT ICING DETECTOR - A method for aircraft surface contamination detection and measurement includes: mounting a laser probe on an airfoil; positioning the laser probe to emit laser energy at multiple pre-determined surface points along the leading edge of the airfoil; and using a processor device for activating the laser probe and obtaining measurement data for generating a surface contour of the shape and accurate measurement of the depth of airfoil icing in the surface target area. The icing data is presented to the pilot in a display that alerts him to the icing and accurately shows the depth and shape of the airfoil icing. | 04-12-2012 |
| 20100231386 | SOLAR-POWERED SENSING - A solar cell generates electricity, a housing for the solar cell and/or sensor is configured to suit an environment in which the housing is to be deployed so that a person who is in the environment and in eye contact with the housing is unaware that the housing is associated with a solar cell and/or sensor. A port couples the generated electricity to a device that senses human activity in the vicinity of the apparatus. | 09-16-2010 |
