Abstract: The present invention concerns a flame detector with optical sensors situated within a housing, which is coupled to a signal collector and focuser enclosure. The enclosure includes a reflective surface or reflective surfaces generally oriented outwardly and in optical communication with the sensors through a shield window exposing the sensors; the shield window is situated between the enclosure and the housing of the flame detector. The enclosure may have a conical shape, a parabolic shape, and may include convex or concave surfaces that reflect emission signals from an emission signal source to the sensors in optical communication with the reflective surfaces. The enclosure is thus adapted to collect emission signals and narrow or focus a field of view of the sensors, thereby increasing a detection range between the flame detector and an emission signal source such as a flame source.

Abstract: A collapsible hammock support is disclosed which comprises a pair of generally parallel horizontal support members, each having connected thereto at each end thereof a pair of upright support members. Each upright support member is connected to one of the horizontal support member by pivoting support member connecting means. The upright support members are each connected to one other upright support member at their upper ends by a pivoting upright support connecting means. Each pivoting upright support connecting means further includes a swiveling hook. In use, the hammock support is removed from a nylon carrying bag in its collapsed position, and the horizontal support members are laid onto a flat surface. Then the upright support members are pivoted up and away from the horizontal support members, and the horizontal support members are pulled away from each other, putting the hammock support is a fully extended position.
