Abstract: A medical bed frame may include a base frame, a pair of side members selectively movable laterally towards or away from the base frame, a first and second drive assembly each comprising: a first and second pair of cams configured to move the pair of side members, and a central linkage for rotating the first and second pair of cams, a first actuator operatively connected to the central linkage of the first drive assembly and the base frame, and a second actuator operatively connected to the central linkage of the second drive assembly and the base frame, wherein the first and second actuator are configured to selectively move the central linkage in one of a first direction and a second direction, whereby selective movement of the first actuator and the second actuator results in lateral movement of the pair of side members towards or away from the base frame.

Abstract: Disclosed are example embodiments of a sectional interlocking plant support system providing a stand for supporting growing plants in soil comprising a stake and a pole, coupled to the stake or other devices, the pole comprising a porous tubular body, the porous tubular body formed by a plurality of porous openings on the pole, the pole configured to be stackable on a second pole, the height being adjustable be selecting a number of poles to connect together. The porous openings on the pole comprising at least one hole shaped in at least one of a circle, a triangle, a square, a hexagon, a pentagon, a heptagon, an octagon, a nonagon, a polygon having more than nine sides, or a irregular shape.

Abstract: A method for calculating checksums includes calculating a first checksum based at least in part on a first block of data, and calculating a partial checksum based at least in part on a second block of data. The second block of data comprises a data portion followed by a fill portion, the fill portion having a length equal to a length of the first block of data. The first checksum and partial checksum are combined to form a second checksum for a total block of data, the total block of data comprising the first block of data and the data portion of the second block of data.

Abstract: A dynamic recovery system comprises a plurality of render nodes each adapted to render data received from a master node. Each of the render nodes is further adapted to receive a render command from the master node indicating a portion of the data to be rendered by the corresponding render node. The system also comprises a control application coupled to each of the render nodes and adapted to automatically reallocate the portion of the data rendered by at least one of the render nodes among a remaining portion of the render nodes in response to an event corresponding to the at least one render node.
