Abstract: A system for transporting inventory items includes an inventory holder and a mobile drive unit. The inventory holder has a frame with device openings. The mobile drive unit is operable to dock with an inventory holder and undock with an inventory holder. When undocked from an inventory holder, the mobile drive unit is further operable to traverse a path from a first location to a second location. The path passes through at least a first device opening of the inventory holder such that the mobile drive unit passes beneath the inventory holder while moving along the path.

Abstract: A dry sidewall sprinkler and system and methods of installation provide extended coverage for ordinary hazard commodities. The preferred sprinkler and systems provide for sidewall ordinary hazard fire protection beneath a sloped or horizontal overhang extending from a structure by at least ten feet proximate to a garage or loading dock in accordance with applicable sections of NFPA-13 (2007).

Abstract: A system for transporting inventory items includes an inventory holder capable of storing inventory items and a mobile drive unit. The mobile drive unit is capable of moving to a first point with the inventory holder at least one of coupled to and supported by the mobile drive unit. The mobile drive unit is additionally capable of determining a location of the inventory holder and calculating a difference between the location of the inventory holder and the first point. The mobile drive unit is then capable of determining whether the difference is greater than a predetermined tolerance. In response to determining that the difference is greater than the predetermined tolerance, the mobile drive unit is also capable of moving to a second point based on the location of the inventory holder, docking with the inventory holder, and moving the mobile drive unit and the inventory holder to the first point.

Abstract: A method of rotating an inventory holder includes moving an inventory holder towards a rotation area along a straight segment of a path with a first face of the inventory holder facing a first direction. The rotation area includes a portion of a workspace designated for rotation of inventory holders. The method further includes moving the inventory holder into the rotation area along a first arced segment with an orientation of the first face perpendicular to the first arced segment. The method additionally includes executing a rotation maneuver within the rotation area and moving the inventory holder out of the rotation area along a second arced segment with a second face facing the first direction.

Abstract: A method for fulfilling inventory requests includes receiving an inventory request requesting an inventory item and selecting the requested inventory item from an inventory holder. The method further includes storing the requested inventory item in an order holder associated with the inventory request and moving the order holder to a storage space. In addition, the method includes detecting a triggering event and in response to detecting the triggering event, retrieving the order holder from the storage space.

Abstract: A method for transporting inventory items includes moving a mobile drive unit to a first point within a workspace. The first point is a location of an inventory holder. The method further includes docking the mobile drive unit with the inventory holder and moving the mobile drive unit and the inventory holder to a second point within the workspace. The second point is associated with conveyance equipment. The method further includes moving the inventory holder to a third point within the workspace using the conveyance equipment.

Abstract: An electric vehicle (4) with a rechargeable battery package (5) and a recharging system (1) for recharging the package (5). The package 5 has a plurality of rechargeable cells (50) and an integrated RFID tag (51) that is powered by an independent lithium-ion battery and has first and second memory areas. The first memory area is configured to permanently store identification data specific to the unique identity of the package (5). The second memory area is arranged to accumulate and store data relating to charge and discharge profiles for the package (5), operational conditions reflecting use of the package (5) during at least a portion of its lifetime, an event log recording operation of the package (5) outside of its recommended use parameters, energy status information for the cells (50) and/or event data pertaining to times of disconnection of the package (5) from an electrical circuit.

Abstract: FIG. 7 shows a camera system (700) that operates to time-stamp video content captured from multiple cameras (740) relative to a recorded and time-synchronized location of a portable tracking unit (722). The position of the cameras (740) is known to the system. Based on the time and position data for each uniquely identifiable tracking unit, an editing suite (770) automatically compiles a composite video made up from time-spliced video segments from the various cameras. Video or still images captured by the cameras (740)are cross-referenced against the client address stored in database (760) and related to the assigned, uniquely identifiable tracking unit (722). A server (750) is arranged to use the client address to send reminder messages, which reminder messages may include selected images taken by the composite video. Alternatively, a client (720) can use the client address to access the database and view the composite video.

Abstract: A support assembly for attachment to a substrate, the assembly having a first part comprising a rebated surface to which a sign is securable and a second part having a peripheral wall sized and dimensioned to bound the first part and a continuous facing wall joined to or contiguous with said peripheral wall, the two parts being securable together whereby said continuous facing wall overlies at least part of a peripheral portion of the rebated surface of said first part.

Abstract: A method facilitating the production of an identification plate comprising a rigid backing plate having a peripheral upstanding rim bounding a flat area to receive a carrier sheet, one surface of which is printed with indicia and the other surface of which has a contact adhesive. In the method an edge of the carrier sheet is aligned in registration with the plate and the adhesive surface at said edge contacted therewith; the sheet then being progressively pressed into contact with the plate over the flat area using a pressure roller. The pressure roller has a recess, channel or depression to receive the upstanding rim. The apparatus used includes a housing 10 mounted on a base 11 which has an elongate extension platform 12. The housing contains a roller 13 turned by means of a motor and drive unit 14. The roller has a surface formed by a layer of rubber material 15 which includes a transverse recess or slot 16.
