Abstract: A granular material spreading system is provided. The granular material spreading system includes a spreading machine, a spreading frame, and a tote. The tote is configured to receive a granular, spreadable material and includes an opening allowing the granular material to exit the tote. The tote includes a spring-biased door blocking the opening. The door is opened by the spreading frame during spreading. When the spreading frame is coupled to the spreading machine, the tote is rotatable by the spreading machine between a storage position in which the opening in the tote is facing horizontally toward the spreading machine and a spreading position in which the opening in the tote is facing the ground surface.

Abstract: A material spreading system may include a tote and a spreader attachable to a loading machine. The spreader may include a frame, an inlet, a lift arm, and a discharge mechanism configured to selectively discharge the material onto the ground. The tote may include a container having a plurality of walls enclosing an internal volume for storing a material. An opening may be formed in one of the plurality of walls and communicate with the internal volume. The tote may additionally include a lift arm engaging surface configured to engage the lift arm and permit the lift arm to manipulate the tote. The tote may also include a closure member at least partially covering the opening and configured to selectively permit transfer of the material from the container to the inlet of the spreader in response to the material exerting a force on the closure member.

Abstract: A method for synthesizing sound includes receiving one or more first inputs (80), each including a respective monaural audio track (82). One or more second inputs are received, indicating respective three-dimensional (3D) source locations having azimuth and elevation coordinates to be associated with the first inputs. Each of the first inputs is assigned respective left and right filter responses based on filter response functions that depend upon the azimuth and elevation coordinates of the respective 3D source locations. Left and right stereo output signals (94) are synthesized by applying the respective left and right filter responses to the first inputs.

Abstract: A material spreading system including a spreader and a tote, and related methods, are disclosed. The spreader may include a frame attachable to a loading machine such as a skid loader, an inlet for receiving a material, one or more connector members, and a discharge mechanism configured to selectively discharge the material onto the ground. The tote may include a container for storing the material and one or more connector members. The connector members of the tote may be configured to matingly engage the connector members of the spreader such that an opening in the container aligns with the inlet of the spreader. Accordingly, the material in the container may be transferred from the container to the spreader. Furthermore, the material spreading system may be used in various application including those involving the spread of granular and/or liquid de-icing material over the ground.
