A material handling device for the loosening of forage, in particular silage from a silo. The material handling device is provided with a grab device provided with grab device members of which the edges facing towards each other are provided with cutting elements. The grab device members are movable between a closed position and an opened position, wherein the cutting elements are positioned at an angle with the vertical. This angle is in the range of 25 to 25 degrees, preferably 15 to 15 degrees with the vertical.

Group online communication and collaboration has become part of people's daily life. Therefore, it is critical to provide a meeting initiator to efficiently present his/her information, and control his/her presented information. It is also critical for the speed and efficiently to process the meeting initiator's requests for his/her presented information to be quickly reaching to other meeting participants during a meeting. This invention facilitates a unique user interface (UI) for the meeting initiator to efficiently present information and to control presented information through a unique withdrawing (un-post) operation. Specially, this invention deploys dynamic workspaces technology together with post and un-post (withdraw) operations that greatly improves the speed and efficiency for processing the meeting initiator's requests and for monetizing the meeting activities.

The animal waste collection robot is a robot. The animal waste collection robot automatically collects befoulment generated by an animal. The animal waste collection robot is an automated device. The animal waste collection robot is an independently powered electric circuit. By independently powered is meant that the animal waste collection robot can operate without an electrical connection to an external power source. The animal waste collection robot comprises a vehicle, a crane, a control circuit, and a pan. The control circuit mounts in the vehicle. The crane and the pan mount on the vehicle. The vehicle transports the animal waste collection robot over a patrol route. The control circuit: a) scans the patrol route for befoulment; b) operates the crane to collect the befoulment; and, c) further operates the crane to transport the befoulment to the pan for storage.

A power bucket having a first and second bucket half pivotally secured together about a main axis by a pivot pin. The bucket halves are movable between an open and a closed position. A head is disposed above the bucket halves and at least one arm pivotally connects the head to one bucket half while at least one second arm is pivotally connected between the head and the other bucket half. A cylinder support is pivotally mounted to the pivot pin and one end of a hydraulic cylinder is attached to the pivot support. The other end of the cylinder is attached to the bucket. Upon actuation of the cylinders, the cylinders move the bucket halves so that a cutting edge of the bucket half moves in a substantially horizontal plane.

The virtual presentation technology in this invention can significantly reduce data load on a network and thus reduce the network bandwidth requirement. This allows serving more requests for data transaction over a network with fixed network bandwidth. In addition, with traditional Internet file sharing products, e.g. the then-existed Yahoo Group online service, in order to stop sharing a file, the file must be physically deleted that prevents resharing the file unless expensively recreating them. In addition, traditional email and instant message does not allow a user to delete a previously posted or shared message from a UI of a recipient. Therefore, the user could be embarrassed if the posted message is not proper to the recipient. This invention has overcome the problems to allow user instantly deleting posted information of file or folder from recipient's UI without physically deleting the file, and deleting previously posted messages from recipient's UI.
