Provided herein are devices, systems, and methods for measuring waste material weight within two or more waste collection bins The bins can be measured using one or more waste measurement devices, and the measurements can be collected and transmitted to networked data storage. Waste measurement data can be collected over time from multiple bin locations, and the stored data can be analyzed and processed to generate reports and ratings of waste collection, disposal, and diversion trends over time. Also provided are waste audit methods and platforms that simplify and streamline data measurement, recording, and analyzing. The audit methods can transfer data electronically to a computer or cloud platform, automatically plot and compare results, and generate reports to be shared with a user or client.

In accordance with an embodiment, a weighing apparatus includes a plurality of weighing scales and a processor. Each of the plurality of weighing scales measures weight of the object to be weighed which is placed on the plurality of weighing scales. The processor calculates net weight of the object to be weighed on the basis of the weight measured by each of the plurality of weighing scales.

A printer communicates with an operation terminal and a weight measuring apparatus. The printer includes a receiving buffer configured to store data, a memory in which an identification information list for the weight measuring apparatus is stored, and a controller. The printer has a weight measuring mode for transferring the data received via a specific interface, to which the weight measuring apparatus is connected, to the operation terminal, and an ordinary mode for executing a command analysis after developing, in the receiving buffer, the data received via all interfaces including the specific interface. The controller is configured to: identify an external device based on identification information of the external device connected to the printer, determine whether the identification information is included in the identification information list, and let the operation mode be the weight measuring mode based on determining that the identification information is included in the identification information list.

APC systems and methods using vehicle mass to assess boardings and alightings of passengers on transit vehicles (e.g., buses). Vehicle mass is determined based on signaled information indicative of a pressure in one or more air bag circuits of an air ride suspension system of the vehicle. In some embodiments, pressure information from three air bag circuits of the vehicle are monitored and reviewed to determine vehicle mass. The passenger count can be estimated based on determined vehicle mass by an Additional Mass Method or an Event-Based Method for example.

Provided is a weighing apparatus with a flowmeter function includes a load sensor unit configured to detect a load of a flow rate calculation target, an A/D conversion unit configured to sequentially convert load signals from the load sensor unit into digital load data at predetermined intervals, an arithmetic processing unit configured to sequentially convert the load data into weighed values to calculate flow rate values, and a storage unit for storing the weighed values. The arithmetic processing unit calculates change amounts in weighed values and calculates a flow rate value based on a flow rate calculation cycle set based on a minimum time by which the change amounts become equal to or more than a change amount in weighed value, the change amount being calculated based on a minimum indication of weighed value and the required resolution of weighed value and satisfying a required resolution.
