Thu, 25 Aug 2016 08:00:00 EDT

A system and method of operating a checked bag reconciliation area of an airport. The method includes transporting a luggage item from an entrance mechanism to one of a plurality of inspection stations. Once the luggage item is at the inspection station, the method proceeds by conducting an inspection of the luggage item by the agent at the inspection station. The step of transporting the luggage item includes transporting the luggage item to the inspection station with the luggage item disposed on an automatic material handling device, and the step of conducting an inspection of the luggage item by the agent includes conducting the inspection of the luggage item while the luggage item is disposed on the automatic material handling device.

Thu, 25 Aug 2016 08:00:00 EDT

A load measuring apparatus includes a waterproof load cell having a load measuring surface, of which the length is substantially equal to a diameter of the substrate, and a base plate that supports the waterproof load cell. The load measuring apparatus is set in a substrate cleaning apparatus like a substrate, and measures a load applied from the roll cleaning tool of the substrate cleaning apparatus using the waterproof load cell.



DIGITAL MECHANICAL MEASUREMENT LAST AND SIGNAL ACQUISITION AND ANALYSIS METHOD THEREOF

Thu, 25 Aug 2016 08:00:00 EDT

The present invention discloses a digital mechanical measurement last, which specifically comprises a last, a three-dimensional strain gauge load cell, a signal amplifier, a data acquisition card, data acquisition system software, and a data line. After a shoe upper surface is sleeved over the digital mechanical measurement last, forces applied on the last by the shoe upper surface are transferred to the three-dimensional strain gauge load cell through a front part of the last and a rear part of the last, so that the three-dimensional strain gauge load cell is strained, which causes a change in a resistance value of the three-dimensional strain gauge load cell, thereby generating a voltage change; the voltage change is processed by the signal amplifier; the data acquisition card transmits data to a PC in which the data acquisition system software is installed over the data line and through a USB interface; the data acquisition system software records, displays, performs computation on, and analyzes signals, which helps a model designer to check and analyze problems existing in shoe models and materials, so as to improve timeliness and accuracy of model modification, save manpower, material resources and research and development time, and make shoe products fitter and more comfortable.
