System and methods for estimating the number of packages in a measurement zone to gauge package flow. A linear array of distance-measuring sensors measures the height profile of a mass of packages conveyed past. The profile is differentiated, and steps in the differentiated profile are counted to detect package edges and to produce an estimate of the number of packages in the measurement zone. The estimate can be used to adjust the speed of the conveyor to provide a constant package flow.

A counting system 100 of the present invention includes an image acquisition means 121 for acquiring a captured image obtained by capturing an imaging area that is a partial area of an object area, a detection means 122 for detecting a person existing in the imaging area from the captured image, a measurement means 123 for, on the basis of a detection result of the person, measuring a staying time that is a period of time in which the person stays in the imaging area, and a calculation means 124 for, on the basis of the detection result of the person and the staying time, calculating the number of persons existing in the object area.

Apparatus, device, methods and system relating to a vehicular telemetry environment for monitoring vehicle components and providing indications towards the condition of the vehicle components and providing optimal indications towards replacement or maintenance of vehicle components before vehicle component failure.
