A method positions a profile of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic component is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one remaining degree of freedom.

The identification and tracking of objects from captured sensor data relies upon statistical modeling methods to sift through large data sets and identify items of interest to users of the system. Statistical modeling methods such as Hidden Markov Models in combination with particle analysis and Bayesian statistical analysis produce items of interest, identify them as objects, and present them to users of the system for identification feedback. The integration of a training component based upon the relative cost of sampling sensors for additional parameters, provides a system that can formulate and present policy decisions on what objects should be tracked, leading to an improvement in continuous data collection and tracking of identified objects within the sensor data set.

A STT-RAM MTJ is disclosed with a composite tunnel barrier comprised of a CoMgO layer that contacts a pinned layer and a MgO layer which contacts a free layer. A CoMg layer with a Co content between 20 and 40 atomic % is deposited on the pinned layer and is then oxidized to produce Co nanoconstrictions within a MgO insulator matrix. The nanoconstrictions control electromigration of Co into an adjoining MgO layer. The free layer may comprise a nanocurrent channel (NCC) layer such as FeSiO or a moment dilution layer such as Ta between two ferromagnetic layers. Furthermore, a second CoMgO layer or a CoMgO / MgO composite may serve as a perpendicular Hk enhancing layer formed between the free layer and a cap layer. One or both of the pinned layer and free layer may exhibit in-plane anisotropy or perpendicular magnetic anisotropy.

A method for Symbol Error Rate (SER) approximation of an SER-based transmission power allocation operation for an Orthogonal Space Time Block Code in a DWCS equipped with multiple transmission Distributed Antennas (DA) geographically dispersed at random. The method for SER approximation includes the steps of: setting multiple combinable antenna subsets from the multiple DAs; selecting a quasi-optimal antenna subset Ag (1≦g≦2n−1) having a quasi-optimal power allocation weight wg based on predetermined power allocation, for each of the set multiple antenna subsets; and calculating an SER approximation value of the selected quasi-optimal antenna subset by applying a Probability Density Function (PDF) of a Signal-to-Noise Ratio (SNR) to the OSTBC SER having symbol constellation of a predetermined modulation scheme. The output of the SER approximation value can be output to a transmitter, or to a space-time encoder of a central processor for optimal power transmission.

In a method for forming an integrated circuit (IC) structure, which incorporates multiple field effect transistors (FETs) with discrete replacement metal gates (RMGs) and replacement metal contacts (RMCs), gate cut trench(es) and contact cut trench(es) are formed at the same process level. These trench(es) are then filled at the same time with the same isolation material to form gate cut isolation region(s) for electrically isolating adjacent RMGs and contact cut isolation region(s) for electrically isolating adjacent RMCs, respectively. The selected isolation material can be a low-K isolation material for optimal performance. Furthermore, since the same process step is used to fill both types of trenches, only a single chemical mechanical polishing (CMP) process is needed to remove the isolation material from above the gate level, thereby minimizing gate height loss and process variation. Also disclosed herein is an IC structure formed according to the method.

The hearing aid carries out the adjustment autonomously.

A detection arrangement and method for directing the sensitivity of an optical knife-edge detection system to its optimal operating point. This is referred to as an increase in the detection dynamic range of the system with advantageous applications for detecting motion of a surface such as for Atomic Force Microscopy as well as detecting acoustic vibrations on unstable surfaces.

Allowing multiple reflections, the sensing beam is maintained on the knife-edge detector even at large angular offsets from the optimal operating point of the basic knife-edge detector. Use of a modified arrangement, with two knife-edge detectors at quadrature ensures near-optimal sensitivity at a detection dynamic range up to forty-fold larger than that of the basic knife-edge system.

This invention is related to a low-complexity MIMO detector in a wireless communication system with near optimal performance. Initial symbol estimation is performed for a transmitted symbol vector. The soft information of the transmitted symbol vector can be more accurately calculated by deemphasizing the LLRs associated with symbols belonging to weak channels that may suffer from poor initial estimation. By combining aspects of both the linear detection and the ML detection, the complexity of the proposed detector becomes orders of magnitude lower than that of a ML detector, but the performance is very close to that of an ML detector.
