Abstract: A measurement system is presented configured for integration with a processing equipment for applying optical measurements to a structure.

Abstract: The invention provides an affordable solar water heater of a simple construction and a process enabling its mass production. The heater is characterized by the tank and the collector being integrated in one structurally uniform unit made of hard plastic, the unit obtained by welding two identical injected subunits.

Abstract: Disclosed is a square knock-down bin with “L” shaped side elements so as to deploy on the base along portions to two adjacent base sides. Each of the side elements includes locking elements along each of its two ends. The locking-element at one of the ends is configured to interlock with the locking element of the adjacent side element to which it abuts. At least one of the side elements includes a displaceable locking-element along one of its two ends. The shape of the side elements is such that disassembled side elements from several bins will nest inside an assembled bin for storage and return shipping.

Abstract: A knock-down bin, formed from molded polymer materials, includes a rectangular base having a length L and a width W, two sides for deploying parallel to the length and a two sides for deploying parallel to the width. The sides meet to define four vertical corner portions. At least one corner portion, and preferably all four, include a hollow vertical corner post integrally formed with one of the sides, the corner post having a vertical hollow channel into which a lateral opening opens. A projection, integrally formed with the other side making up the corner portion, projects through the lateral opening into the vertical channel. A locking element is slidingly deployable within each vertical channel between an unlocked position in which the projection can be inserted and removed from the lateral opening and a locked position in which the locking element engages the projection so as to lock it within the channel, thereby locking together the adjacent first and second sides.
