Abstract: A welding assembly is disclosed. The welding assembly includes a plurality of separately controllable actuators (e.g., pneumatic, having an axially movable ram) to press a corresponding portion of a first workpiece (e.g., a discrete flange of a first stiffener) against a second workpiece (e.g., an outer skin) for welding operations (e.g., via induction welding).

Abstract: An automated order fulfillment system and mobile robot are disclosed, where the mobile robot includes a compliant drive for moving between levels of a multilevel storage structure. In one example, the compliant drive comprises a drive shaft having splines configured to provide rotational play that prevents jamming of a vertical drive gear on the end of the shaft with a rack in a vertical track.

Abstract: A "video fax" system electronically delivers a non-real time, full-motion, sub-broadcast quality facsimile of relatively short segments of video material from an originating location to a receiving location in a short period of time, utilizing selected widely available commercial telephone switched networks. At the originating location, analog source material is digitized, compressed, prepared for transmission and stored temporarily. Digital source material is handled by bypassing the digitization step and part of the compression step, and performing the necessary file conversion. The sending location dials up the receiving location, and a connection is established. The digital file is transmitted over the network. When finished, the connection is terminated. At the receiving location, the material is received, decompressed and converted back to either analog form or digital form, depending on the recipient's preference.
