Abstract: The present invention is directed to a rainwater gutter for collecting rainwater which runs off the roof of a building. The rainwater gutter is formed by connecting two or more gutter sections, such as the outer surface of the gutter is continuous with no visible connectors. The gutter sections comprise one or more keyways running along the length of the gutter section. The keyways receive an elongated keyway for connecting gutter sections end to end.

Abstract: A device and method of using a device for removing water from the trap of a plumbing appliance. In one embodiment, the apparatus provides a housing within which is movably mounted a plunger. An elongate hose is provided at one end of the housing to receive trap water therein upon actuation of the plunger or an inflatable member is provided at one end of the housing to force the trap water by inflating same by actuation of plunger. The disclosure also relates to methods of removing trap water using the apparatus described herein.

Abstract: A system for selecting products is described. The system includes a computer executing a process to retrieve a product aesthetic tag associated with a particular product type selected by a customer. The aesthetic tag contains values that represent aesthetic features of the product and a process to form a result tag that contains a value corresponding to how well aesthetic features of the product match to aesthetic preferences of the customer.

Abstract: Apparatus for determining a range to a coherent light source emitting a coherent light beam, the apparatus including an image sensor and a processor, the processor being coupled with the image sensor, the image sensor including an imaging plane, for capturing an image of the wave front of the coherent light beam, the image including at least one light speckle, wherein the processor identifies the light speckle on the captured image, determines the characteristic diameter of the identified light speckle, and determines the range by squaring the characteristic diameter and dividing the result of the squaring by the wavelength of the coherent light beam and by a proportionality constant.
