In an embodiment, a system for wear monitoring, includes a wear surface, a metallic reflector embedded in the wear surface, a radio-wave transmitter, and a radio-wave receiver. The metallic reflector reflects radio waves transmitted by the radio-wave transmitter for detection by the radio wave receiver. Attenuation of the radio waves between transmission by the radio-wave transmitter and detection by the radio-wave receiver indicates a degree of wear of the wear surface.

A personnel platform facilitates maintenance on a loop sorter of a material handling system in a distribution center. The personnel platform includes wheeled axle assemblies, having left and right wheel hub assemblies connected by a lateral support structure, engaged for longitudinal travel to opposing wheel channels of a section bed of the loop sorter that guide a train of material handling carriages. The personnel platform also includes a carrier platform comprising multiple sub-platforms, such that each sub-platform is pivotally attached to an adjacent sub-platform. Further, the personnel platform includes a rail assembly having upright structures and side rail assemblies attached between an adjacent pair of upright structures. Further, the side rail assemblies extend and retract according to changing spacing between the adjacent upright structures as the personnel platform moves along a curved section.

A system and an apparatus capable of independently driving movers are described herein. The system and apparatus includes: a track that forms a path for movers; a plurality of movers movably mounted on the track for moving along the path; and a plurality of drive elements fixedly arranged along the track. The drive elements each have a surface that is oriented to contact a driven member of the movers. The drive elements are configured to sequentially engage the driven member of a plurality of the movers to provide controlled independent motion of the movers along the track. The drive elements may be driven by rotary motors. A method of independently driving movers is also described herein.

A read chamber device disclosed for use within a radio frequency identification (RFID) scanning enclosure which provides a means of reading a plurality of cartons moving through the enclosure via a conveyor belt. The enclosure is positioned over a section of the conveyor belt, such that the plurality of cartons on the conveyor belt pass directly through the enclosure. The read chamber device that may be positioned centrally to the enclosure and projects a read zone via an antenna positioned centrally within the read chamber device. The read chamber device provides for tuning the read zone via a movable metal plate comprising absorber material components secured to it, that is positioned at variable distances to partially or fully cover the read zone. The metal plate is moved into the read zone to obstruct a percentage of radio frequency energy from escaping the read zone, and thus narrowing the total read field.
