Surface guided knee replacement
InactiveUS20070135925A1Reduce consistencyAvoid large displacementJoint implantsKnee jointsGonial angleTibial surface
An artificial knee joint that includes a femoral component with a specially shaped bearing surface and a tibial component, whose surface interacts with the femoral surfaces. The interaction provides for the motion and stability characteristics of the anatomic knee. The interaction between the femoral and tibial surfaces is such that as the knee is flexed to maximum, the femoral component moves posteriorly on the tibial surface, more so on the lateral side than on the medial side. This is accomplished by the interaction of a projecting tibial post inside a cupola in the center of the femoral component, and by the saggital radius on the medial side being smaller than that on the lateral side. The prevention of anterior sliding of the femur on the tibia in early flexion is accomplished by the interaction between a distal-anterior recess on the medial side of the femur and an apposing raised pad on the tibial surface. Rotational laxity at all angles is allowed by the presence of only one recess pad and by non-conforming femoral-tibial surfaces on the lateral side.

Symbol-directed weighting in parallel interference cancellation
InactiveUS6931052B2Improve consistencyImprove the level ofRadio transmissionInterference cancelationComputer science
The present invention provides for improved parallel interference cancellation. An input signal composed of multiple user signals is processed over a select time duration. The input signal is separated into individual signals corresponding to each of the multiple users and demodulated to recover symbols for each of the individual signals. The recovered symbols are processed based on the consistency of previous estimates of the given symbol to provide weighted symbol estimates. The respective weighted symbol estimates for each of the users are modulated with the appropriate coding and processed using channel estimates to create individual, regenerated signals. For each user, the regenerated signals for the other users are subtracted from the original input signal to form new individual signals. The new individual signals are each demodulated and reprocessed for multiple iterations. The output of the last iteration is used to form the final symbol decisions for each user signal.

Battery pack with internal serial structure and manufacture method thereof
InactiveCN102104167AMeet voltage requirementsReduce volumeFinal product manufactureSecondary cells manufactureElectrical batteryEngineering
The invention provides a battery pack with an internal serial structure and a manufacture method thereof. The battery pack comprises N pole groups, N-1 baffles with conductivity, an electrolyte and sealing rings in a battery shell and top covers on the battery shell. The manufacture method comprises the following steps of: separating two adjacent pole groups with the baffles; connecting the anode of one pole group with a baffle; connecting the cathode of the other pole group with the other edge of the baffle; and serially connecting the adjacent pole groups. The battery pack is designed according to a needed voltage so that a plurality of unit battery cores are connected serially in the same battery shell for use as a whole to meet the voltage requirement. The battery pack provided by the invention has smaller battery size and lighter mass under the same voltage while meeting the voltage requirement on various electric appliances and has low requirement for a battery packing technology. Meanwhile, due to no connectors for conduction among cell batteries when the batteries are combined, the external short circuit of the batteries can be reduced.
