Title: Four compartment knee
Inventor: BECKMAN AUDREY
IPC: A61F2/38
Filed: 1999-02-26
Abstract: A femoral knee implant includes a fourth compartment of articulation. The superior posterior articulating surface is achieved by first increasing the thickness of the superior posterior condylar portion of the femoral component to widen the superior posterior edge of the posterior condyle. Second, the newly created surface at the superior posterior condyle is smoothly rounded to provide an articular surface with no sharp changes in the surface contours. In one embodiment, the fourth articular compartment of this invention is provided in a one piece femoral design. In another embodiment, it is provided as a modular addition to an existing prior art femoral component. In another embodiment, the fourth compartment is combined with a posterior stabilized (PS) TKR design that includes a tibial post and cooperating femoral cam characterized by low engagement of the cam on the spine.

Abstract: It is an object of the invention to provide a method of continuously adding a large amount of fats and oils to porous fodder. To attain the object, continuous and efficient addition of fats and oils is effected in a continuous type fat and oil addition apparatus by charging a porous fodder, which is formed by an extruder to have a multiplicity of voids therein, together with additive fats and oils into the continuous type fat and oil addition apparatus, in which inside pressure is reduced to a predetermined pressure value, and taking them out from the fat and oil addition apparatus after holding them for a predetermined period of time. Accordingly, it is possible to continuously and efficiently add fats and oils to the porous fodder with a high content.

Abstract: Transform coefficients of audio signal samples are grouped into subbands. A predetermined number of subband bit allocation patterns (encoding categorizations), specifying parameters including quantization step size, dead zone, maximum bits, vector dimension, and a variable length code for each vector, are available. Subband bits are assigned in accordance with the quantized power distribution over the subbands, and the bit allocation patterns selectively chosen in accordance with a fidelity criterion and a maximum bit rate. The quantized power, transform coefficients and the selected bit allocation pattern (encoding categorization) identity are transmitted to a decoder, where, using the known encoding categorization, the coded data are inverse-transformed and dequantized into a reconstructed audio signal.

IPC: G06F12/16
Filed: 1997-11-07
Abstract: A system and method for maintaining logically consistent backups using minimal data transfer are presented. A system comprises a backup system having a backup storage device (24) and one or more primary systems (12) having mass storage devices (20) that are to be backed up on the backup storage device (24). The primary systems (12) track changes made to the mass storage device (20).
