Abstract: A multispectral inspection (MSI) device for analyzing an electronic item having a printed circuit board (PCB). An electronic power supply powers the electronic item in accordance with one or more test vectors. An optical imaging scanner, terahertz (THz) imaging scanner, and a functional imaging scanner are each operative to scan the electronic item. An electronic processor is programmed to scan the various scanners and control the power supply to acquire optical, THz, and functional images of the electronic item. The images are combined to form a standard three-dimensional (3D) signature and artificial intelligence (AI) classifiers are applied to the 3D signature to perform non-destructive analyses of the electronic item.

Abstract: A crane, with a pendant supported boom rotating in a vertical plane, the pendants operable to rotate said boom by a mast rotating in a vertical plane, means to rotate the mast, and said means to rotate operable to restrain the mast from counter rotation; wherein the improvement being a clutch releaseably coupling said mast to said boom, said clutch operable to restrain rotation of said boom in either direction in the absence of rotation of said mast.

Abstract: A structural boom, as for a crane, including at least one corrugated section; a telescoping boom crane having a multi-sectioned, telescopically extending boom; and an extensible pendant support system including a plurality of pendants.

Abstract: A multi-sectioned, telescopically extending column. This invention includes an extension mechanism to extend the column and support the column sections during extension, and a locking mechanism to lock each column section to the next when the column reaches its extended position. The column is particularly well suited for use as a crane boom, where individual boom sections are nearly fully extended each from within the other to minimize overlap between adjacent sections and reduce dead weight resulting from such overlap.

Abstract: A telescoping boom crane having a multi-sectioned, telescopically extending boom and an extensible pendant support system. The extending boom includes boom sections that are extensibly receivable within the adjacent boom section. The boom sections are made of a sheet material. A releasable locking mechanism may be attached to the boom sections to secure the boom sections. The extensible pendant support system includes a plurality of pendants. The pendants are extensibly receivable within an adjacent pendant. The pendant support system at least partially supports the boom when a load is applied to the boom. Further, the support system may include a forestay length locking device functioning to prohibit extension of a subsequent pendant from an adjacent pendant once the former pendant achieves an extended position.
