Abstract: A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to be filled with a gas. The quality control system includes a computational system including a processor and a memory, a manifold defining a passageway extending between an inlet port for receiving the gas and an outlet port, and at least one sensor in electronic communication with the computational system. The sensor is arranged to measure a physical property of the gas and transmit a signal to the computational system corresponding to the physical property of the gas. The computational system analyzes the physical property of the gas, accesses a threshold value corresponding to the physical property, compares the physical property to the threshold value, and assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.

Abstract: A shopping cart provides a carrier adapted for carrying items, which carrier is pivotally mounted to a support. Further, a wall structure is provided, also pivotally mounted to the support, which wall structure and carrier can be pivoted to a position to provide a carrying space defined by the carrier and the wall structure. Further, the support and a base upon which the support is mounted are of molded integral, and thus relatively inexpensive, constructions and have an open end such that one of the shopping carts can be easily and conveniently nested into another of the shopping carts.
