Abstract: A waste collection system includes waste containers for receiving waste, sensors associated with the waste containers, a server system for receiving signals from the sensors. The server system determines that a waste container needs to be collected, determines a location of the waste container and whether the waste container is in a waste collection vehicle accessible location. A notification is sent to an operator of the waste container if the waste container is not in a waste collection vehicle accessible location. When the waste container is moved to a waste collection vehicle accessible location, an optimal waste collection strategy for a waste collection vehicle to collect waste from the waste container at the waste collection vehicle accessible location is determined and the waste collection vehicle is routed to the location of the waste container.

Abstract: A plug for detecting tampering of a container is configured to close an opening of the container. The plug includes an attachment device for attaching the plug to the opening of the container, a motion sensor for sensing rotation of the plug with respect to the container, a communication device for communicating with a server, a microcontroller unit and a memory unit. The microcontroller unit is configured to compare a sensed rotation of the plug to a service schedule stored in the memory and detect the tampering of the container based on the comparison.

Abstract: A waste collection system (10) includes one or more waste containers (20) for receiving waste (50), a server system (100) for receiving one or more signals via a wireless communication network (70) from sensor arrangements (30, 40) included on the one or more waste containers (20) for sensing a waste status of the one or more containers (20). Beneficially, the server system (100) is operable from receiving the one or more signals to compute an optimal strategy for one or more waste collection vehicles (150) to collect waste from the one or more waste containers (20). The waste collection system (10) is capable of supporting a competitive bidding arrangement for implementing collection of waste (50) for the one or more waste containers (20).

Abstract: A plug for detecting tampering of a container the plug being used to close an opening in a lid of the container. The plug includes an attachment for attaching the plug to the opening in the lid of the container by rotating the plug with respect to the container, a motion sensor for sensing rotation of the plug with respect to the container and a communication device for communicating with a server.

Abstract: A sensor device for remote monitoring of a waste container, the sensor device including one or more sensors for sensing an amount of waste and an environment within the waste container, a data processing unit for processing sensor signals indicative of the amount of waste and the environment within the waste container, a communication interface for enabling the sensor device to communicate information corresponding to the sensor signals to a remote location. The sensor device is mounted to an upper lid of the waste container in a spaced apart manner by placing one or more spacing elements and a heat reflecting layer arranged between the sensor device and the upper lid to provide a thermal barrier between an underside surface of the waste container lid and the sensor device.

Abstract: Disclosed is a method for monitoring a fill rate of a container and communicating it, which container comprises at least a first sensor which is a fill rate sensor. The method comprises receiving an operational model from a server, comprising a predefined maximum and/or minimum value of the fill rate. The method also comprises measuring the fill rate of the container. The method further comprises comparing the measured fill rate with the operational model. The method also comprises communicating the fill rate to the server, if the fill rate is equal or above the predefined maximum fill rate and/or if the fill rate is equal or below the predefined minimum fill rate.

Abstract: Disclosed is a method for identifying location of a first container within a group of containers. Each container has an identification code and includes a sensor unit. The sensor unit includes communication means and a movement detector. The method includes at least a first sensor unit of the first container transmitting a first message including a first identification code of the first container, and at least one communication module receiving the first message. The at least one communication module analyzes the received first message, compares the received first identification code to a list of stored identification codes, updates the list of stored identification codes by addition of the first identification code when the first identification code is absent from the list, and transmits a second message to a server, the second message including the first identification code for the server to update the location of the first container.

Abstract: A sensor device used in remote monitoring of waste within a waste container includes a sensor arrangement for monitoring the waste and for generating a corresponding waste-indicative signal, a data processing arrangement for receiving the waste-indicative signal, a wireless interface coupled to the data processing arrangement for enabling the data processing device to emit wireless signals including information derived from the waste-indicative signal, and a power source for providing power to operate the sensor device. The sensor arrangement additionally includes a temperature sensor for measuring a temperature of at least the power source, and the data processing arrangement is operable to be switched from the second reduced-power mode to the first activated mode as a function of the temperature measured by the temperature sensor. This enables power saving and increased service life of the sensor, battery, and the waste container.
