Title: Expandable bale carrier and feeder
Inventor: KUHNS ABE B
IPC: A01D90/12
Filed: 1992-05-08
Abstract: An expandable hay bale carrier and feeder and flexible vehicle for feeding livestock include a wheeled chassis with a bed thereon for supporting the bales, a pair of spaced end walls and a pair of spaced side walls. The side walls are mounted by a telescopically slidable assembly to move transversely of the bed between a first maximum width position spaced from the end walls and a second minimum width position adjacent the end walls. As the livestock feed and reach for more hay the force which they exert against the side walls automatically moves the side walls toward the minimum width position as the hay is consumed, and the respective ends of the side walls may move independently of each other to compensate for unequal consumption of the hay. The side walls may be opened to permit the loading and unloading of the hay bales and the livestock may feed from all sides of the feeder. The chassis is flexible to permit it to twist about a longitudinal axis if one of the wheels encounters a change in elevation in the terrain as the carrier and feeder is being moved in the field and permits the carrier and feeder to assume a low center of gravity.

Abstract: Des coefficients de courant alternatif dans un bloc de coefficients de transformation orthogonale représentant une image numérique sont quantifiés avec une taille d'échelon de quantification sélectionnée en fonction des aspects suivants : le bloc représente une image en mouvement ou une image fixe, la finesse du motif pictural dans l'image, la position des coefficients dans le bloc, et si les coefficients représentent les informations de luminance ou de chrominance dans l'image. La finesse du motif pictural est déterminée selon le nombre de coefficients de courant alternatif qui sont supérieurs à une première valeur de seuil relativement faible. Si un des coefficients de courant alternatif excède une seconde valeur de seuil relativement importante, le bloc est considéré comme ayant une forte activité, c'est-à-dire un motif fin et est donc quantifié avec un échelon de quantification important.

Title: Apparatus for Modelling Interaction of Rigid Bodies
Inventor: GOYAL SURESH
IPC: G06F17/50
Filed: 1993-08-04
Abstract: Apparatus for modelling or simulating the dynamics of interacting rigid bodies. In the apparatus, the rigid bodies are represented as convex polyhedra. Contacts between the bodies are modelled as contacts between a face and a vertex or between edges. All other types of contact are reduced to these types. The beginning or end of a contact is determined by means of linear interpolation. The dynamics of the contacts are modelled as convicts between massless rigid surface elements which are connected by massless viscous layers to the objects. The viscous layer connecting a surface element to its object permits the surface element to move either perpendicular to or tangent to the plane of contact. The properties of the viscous layers determine the dynamics of the contacts. In the implementation, the properties are described by means of two systems of springs and dampers, one permitting motion in the perpendicular direction and the other motion in the tangential direction. Parameters of the spring and damper systems may be set as required to model contacts between various kinds of objects.
