20130207819 | STABILITY CORRECTION FOR A SHUFFLER OF A SIGMA-DELTA ADC - A sigma-delta analog-to-digital converter (“ΣΔ ADC”) may include a loop filter, ADC, a feedback digital-to-analog converter (“DAC”), and a control circuit. The feedback DAC may include several unit elements (resistors, capacitors, or current sources) that, ideally, are identical to each other but vary due to mismatch errors introduced during manufacture. Mismatch errors may introduce signal errors that generate undesirable noise frequencies and non-linearities in a ΣΔ ADC output signal. Embodiments of the present invention provide a stability corrected second order shuffler that allows for the shaping of the frequency response by the ΣΔ ADC to reduce the effect of the mismatch error between DAC unit elements. The second order shuffler may include accumulation correctors, to suppress saturation for accumulators within the shuffler. The suppression may compress the range of accumulation values for each accumulator while maintaining context for the values to stabilize operation of the second order shuffler. | 08-15-2013 |

20130207821 | METHOD AND APPARATUS FOR SEPARATING THE REFERENCE CURRENT FROM THE INPUT SIGNAL IN SIGMA-DELTA CONVERTER - An integrator system may have a pair of sampling circuits each having a sampling capacitor to sample a respective component of a differential input signal, and an integrator having inputs coupled to outputs of the sampling circuits. The system may have a shorting switch coupled between input terminals of the sampling capacitors. The shorting switch may be engaged during an interstitial phase between sampling and output phases of the sampling circuits. By shorting input terminals of the sampling capacitors together, the design reduces current drawn by the system and, in some designs, severs relationships between current draw and information content sampled by the system. Configurations are disclosed for analog and digital input signals. | 08-15-2013 |

The multichannel system may stand alone, or may be coupled to a receiving circuit having an input coupled to an output of the multiplexer. In some instances, the receiving circuit is an analog to digital converter. | 03-20-2014 |

20090155332 | REPLACEMENT BONE TISSUE - Bone replacement tissue suitable for bone grafting procedures, said bone replacement tissue being grown in a host until suitable for translocation into a desired position in a patient, and methods for manufacturing said bone replacement tissue. | 06-18-2009 |
20110076316 | SCALABLE MATRIX FOR THE IN VIVO CULTIVATION OF BONE AND CARTILAGE - The present invention provides implantable receptacle devices (and methods) for use in bone and tissue regeneration which provide immediate structural stability and strength to a zone where tissue regeneration is required. By virtue of their size, shape and construction, the devices are scalable, modular, structurally stable, self-stacking in three dimensions, can be aggregated to an anatomically accurate shape, and hold various materials delivered into the implant area so as to create a highly regenerative micro-environment. They can be implanted via less invasive surgical procedures, and because they act as external scaffolding as well as being imbedded as an integral part of a matrix for the effective and rapid regeneration of bone and cartilage in vivo, they may provide significant advantages to patients or subjects in terms of reduced pain, faster healing and fewer complications. | 03-31-2011 |

20080228190 | IN SITU PATELLAR FIXING SYSTEM - Disclosed is a patellar cutting jig for use in a knee joint surgical procedure. The jig grips and holds a patella in situ in spatial reference to the femur to enable the appropriate cut to be made to the patella to accurately accommodate the patello-femoral gap at the replacement knee joint. The patella jig has a referencing component that provides a landmark connection between the patella jig and the femur which enables the patella clamp of the jig to be oriented relative to the reference feature prior to gripping the patella. Thus a patella held in the clamp is fixed in the cutting jig an appropriate orientation relative to the femur prior to its resection. Cutting the patella while it is referenced to the patellar groove on the femur increases the accuracy of the resection. | 09-18-2008 |
