Abstract
A device comprises a crossmember. The crossmember is supported by one or more weight sensors, such that a total weight of the crossmember and any supported load may be measured. One or more strain gauges are affixed to the crossmember. An accessory may comprise a portion to support an inventory item, such as a hook, shelf, bin, basket, and so forth. The accessory also includes an engagement feature to mechanically engage a portion of the crossmember. Several accessories may be engaged to the crossmember. As the load on the accessory changes, such as due to a pick or place of items, a total weight change may be determined by summing the output from the weight sensors. Data from the strain gauges may be used to allocate the total weight change to a particular accessory, allowing for the determination of the weight change for that particular accessory.
