Patent number: 12059073Abstract: An apparatus includes a crossbar to which a plurality of accessories using different mechanical interfaces may be attached and detached. The crossbar is instrumented and provides information, such as a weight change due to addition to, or removal of, items from an accessory on the crossbar. An extensible bracket attaches the crossbar to a supporting structure, decreasing mechanical strain on the crossbar due to minor misalignment of the supporting structure. Accessories such as wire hooks, shelves, bins, and so forth may be supported by the crossbar. A tether device, locking cam device, or clip device may be used to prevent lateral movement of components such as the accessories or the entire crossbar relative to its supporting structure. A baffle may be affixed to the crossbar to constrain airflow for operation in a temperature-controlled case.Type: GrantFiled: March 23, 2021Date of Patent: August 13, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Gregory Kim Justice, Venkata Srikiran Bodapati, Rafiuddin Arif Ahud, Ryan Q. Long, Michael Morgan, Justin William Andersen, Vahideh Kamranzadeh, Nirmal Doshi, Nathan Pius O'Neill, Forrest Alexander Bourke, Rachel M. Burroughs

Patent number: 11796378Abstract: An apparatus includes a platform or other accessory that is supported by one or more transducer assemblies using piezoelectric transducers. In one implementation, a saddle structure provides mechanical support to a platform while transferring force from a load onto a portion to which a pair of piezoelectric transducers are affixed. As a load on the saddle changes, the resulting change in strain on the portion produces signals from the piezoelectric transducers. In another implementation a beam provides mechanical support to a platform or other accessory. A pair of piezoelectric transducers are affixed near a strain concentrator, such as a hole in the beam, produce signals indicative of a change in load on the beam.Type: GrantFiled: June 25, 2021Date of Patent: October 24, 2023Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Robert M. Riggs, Andrew James Pierce, Cody Ryder Volk, Alexander Eugene Choi, Rafiuddin Arif Ahud, Graham Cyril Jordan, Paul Eugene Munger, Jacob Drewniak

Patent number: 11766140Abstract: A multi-interface apparatus includes a crossbar to which a plurality of accessories using different mechanical interfaces may be attached and detached. Accessories such as wire hooks, shelves, bins, and so forth may be used. The different mechanical interfaces may include slatwall, pegboard, and saddle mount. Multiple accessories with different types of mechanical interfaces may be supported simultaneously by the crossbar. The crossbar may be instrumented. For example, load cells may be used to determine the weight on the crossbar.Type: GrantFiled: March 18, 2020Date of Patent: September 26, 2023Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Gregory Kim Justice, Nicholas Franklin, Rafiuddin Arif Ahud, Ziwei Xia, Nir Charny
