Abstract: A joist suitable for use in a composite concrete floor is disclosed. The joist comprises a top chord, a bottom chord; and a vertically extending intermediate web having a top end secured to the top chord and a bottom end secured to the bottom chord. The top chord comprises a pair of longitudinally continuous symmetrical chord members facing each other and embracing the top end of the web. Each of the chord members includes a vertical portion secured to the top end of the web and a slanting upper extension extending above and away from the top end of the web, thereby providing a shear connecting portion and a flared opening, between the two facing chord members, giving access to the web and improving access of a welding tool to the area between the symmetrical portion of the top chord and the web member that must be joined together.

Abstract: The present invention allows the planner of a multi-storey building project to remove concrete from the critical path of the structure and envelope completion. The system of the present invention accommodates various floor depths, conforms to alternative stud depths and, acts as a compression/tension member for a building during and after construction. The invention relies upon the use of cold-formed metal that is shaped to provide a ring beam which will accommodate the various criteria. A basic shape configuration has been generated to provide the most efficient utilization of materials. Simplifying installation for the many variable conditions that occur in buildings is therefore provided by this modular design, wherein designers and contractors can easily select and use specialized components to meet all design and construction requirements.

Abstract: A sensor assembly adapted for remotely monitoring spaces such as residences or businesses, with enhanced privacy. In one exemplary embodiment, the sensor assembly is configured to look like a convention passive infrared device (PIR), and includes a CMOS camera and associated data processing. The data processing selectively alters the image data obtained by the camera so as to allow a remote operator to view only certain features of the data, thereby maintaining privacy while still allowing for visual monitoring (such as during alarm conditions to verify “false alarm” status). Alternate system configurations with local and/or remote data processing and hardwired or wireless interfaces are also disclosed.

Abstract: A sensor assembly adapted for rapid removal and replacement of the sensor by the user, as well as enhanced aesthetics and functionality. In one exemplary embodiment, the assembly comprises a camera (e.g., CCD or CMOS) and housing which is removably attached to a support element. The support element is coupled to a mounting surface (e.g., wall, vehicle, etc) via a coupling mechanism which provides a plurality of degrees of freedom. Electrical connections between the camera and support element are made integral with mating surfaces of the camera assembly housing and support element, thereby obviating the need to de-terminate and re-terminate by hand. The support element may also be made universal so as to adapt to a number of different sensor types, thereby allowing the user to rapidly “swap out” sensors of different type as desired. Methods for manufacturing the invention are also disclosed.
