Abstract: The present invention is related to a self-propelled forage harvester (1) comprising one or more sensors (15) mounted on the spout (30) of the harvester, and configured to measure the speed of the crop flow passing through the spout. The harvester is further equipped with a feed roll control unit (8) configured to receive a signal from the sensor and further configured to stop the rotation of the feed rolls (4,5) when the speed is lower than a pre-defined threshold, indicating that a blockage has occurred in the spout. According to an embodiment, the harvester is further provided with a hatch door arranged in the bottom of the spout. The hatch door enables the removal of the blocked crops after a blockage has occurred. In this way, a blockage can be detected quickly and removal of the blockage may also be realised in a fast and efficient way.

Abstract: A method of aggregating and updating heterogeneous data objects for a client subsystem includes: storing a set of data object definitions, each defining a mapping between an aggregated data object format and a plurality of supplier data object formats; storing a set of update definitions, each defining a mapping between an aggregated update operation and a plurality of supplier update mechanisms; receiving a data object in a supplier data object formats; selecting, based on the supplier data object format of the received data object, a data object definitions and generating an aggregated data object according to the selected definition; presenting the generated aggregated data object to the client subsystem; receiving an aggregated update operation from the client subsystem for updating the aggregated data object; and selecting, based on the received aggregated update operation, one of the update definitions and initiating a supplier update mechanism according to the selected update definition.

Abstract: A neck trainer for alleviating head, neck, and shoulder pain, and stretching, strengthening, and developing the core muscles of the neck includes an annular headband section configured to fit snugly on a forehead of the user, around a head of the user and above ears of the user; and an annular weight section delineated from and connected to the annular headband section, above the annular headband section. The annular weight section with the headband section is vertically spaced upwardly so that the annular weight section is disposed substantially at a top of or above the forehead of the user, increasing the moment of force provided by the annular weight section when the user moves the user's head, alleviating head, neck, and shoulder pain, and stretching, strengthening, and developing the core muscles of the neck.
