We have developed an automatic method that efficiently detects the defect signatures of substrates and identifies possible problems pertaining to LSI/TFT-LCD manufacturing processes and tools. This system, which has no built-in libraries, can be applied to the mass production line of thin film devices. This method is useful to quickly detect problems that have been overlooked thus far.

Recently, solar energy generation and wind power generation have been introduced to electric power system. But, as for this natural energy, influence such as frequency fluctuation is exerted on electric power system, which is a fundamental problem in operation of a small grid system such as micro-grid. These systems should provide appropriate power quality compared to a large grid. However, using the telecommunication line for monitoring and controlling the system devices is costly, as an alternative method, autonomous distribution control which enables local power supply and demand control is also required in design and operational stage. This paper discusses benefits of these methods conducting cost evaluation.

In the recent years, the using of renewable energy power generation method is increasing. For power system stability in installation of renewable energy power generation, the mitigation of influence is very important. A micro-grid is a network system that attempts the coexistence of utility grid and distributed generation. The micro-grid should take a connection system form that adjusts to the area. This paper discusses different interconnections of micro-grid and the interconnection stability. The evaluation models in the micro-grid stability are tie line power flow and frequency deviation.

In a clustered micro architecture design, the execution core which has large RAMs, large CAMs and all connected result bypass loops is partitioned into smaller execution cores that are called clusters. Clustered microarchitecture can allow a scalable core design because intra-cluster operation remains fast regardless of entire execution width of the core. But localization of critical memory transfers (store-load-consumer) is still a problem. In this work, we propose a technique named "distributed speculative memory forwarding (DSMF)" that localizes critical memory transfers into a cluster. DSMF learns memory dependences at retire stage, steers dependent pair of the store and the consumer to the same cluster, transfers data locally in the cluster. We show that the IPC improvement of 15% was obtained by this localization on the baseline clustered microarchitecture.

This paper reviews the in-vitro experiments made to estimate the impact of the EMI from cellular phones on implantable cardiac pacemakers in Japan. The approach of the EMI test system is to directly expose the pacemaker to the near- and far-fields generated by a dipole antenna and/or an actual cellular phone. The results were used by the electric medical equipment study group of Japan to establish guidelines for the use of current Japanese cellular phones. An actual test system of cellular base-station EMI with a pacemaker is presented. To simulate a realistic EMI situation, a torso phantom with an installed pacemaker is newly constructed A multi-carrier generator is used as the base-station RF signal source. A typical commercial base-station antenna is used to generate microwave EMF similar to that emitted from cellular base-stations. The results show that EMI impact is determined by the maximum averaged power, not the peak power, of the base-station RF signal.

We propose an automatic arrhythmia diagnosis system which can distinguish atrial rhythms from ventricular rhythms. This system discriminates the origination of cardiac stimulation by analyzing QRS complex beat by beat with Fourier analysis and neural network pattern recognition, and then diagnoses arrhythmia with measurement of heart-rate. As well as implementation into a conventional single-chip processor, capability for instantaneous diagnosis and applicability to implant devices are demonstrated.

We developed a system which detects life threatening ventricular arrhythmias with respect to each beat. In this paper, we applied the system to human intracardiac electrogram (EGM) data for demonstrating the clinical potential. The system analyzes Fourier spectrum of the EGM signal corresponding to an individual QRS complex, and classifies it to three kinds of rhythm origins using a neural network. In our study, supra-ventricular rhythms were classified from ventricle originated rhythms with high sensitivities and specificities.

The authors developed an arrhythmia diagnosis system which distinguishes supra-ventricular events from ventricular ones. The system uses a power spectrum of QRS complex to discriminate the origin of a rhythm, and then classifies 12 types of arrhythmias based on the heart-rate end its variations. The system was evaluated with human ECG data. Two kinds of origin, supra-ventricular and ventricular, were distinguished with more than 98% sensitivity and specificity. The discrimination was conducted with a simple processing of weighted summation of two power spectrum inputs (4 and 8 Hz). In arrhythmia classification, there were 14 misclassified beats among 2234 beats, but no clinically fatal errors were found.

High performance digital-analog mixed devices are fabricated on a high resistivity MCZ Si substrate with low oxygen in order to suppress substrate noise from digital to analog circuits. The low oxygen prevents substrate resistivity reduction due to thermal donor occurring during device fabrication process. Good characteristics of digital, analog and power amplifiers can be realized by optimizing the process of oxynitride, halo implantation and salicide. In 0.11 /spl mu/m CMOS, high drivability, that is, 770 /spl mu/A//spl mu/m for NMOS and 330 /spl mu/A//spl mu/m for PMOS was achieved at Ioff=10/sup -9/ A//spl mu/m. And fT value of 90 GHz for NMOS and 48 GHz for PMOS can be achieved. Additionally, high efficiency of 68% at 2 GHz operation can be realized in power amplifier with 0.30 /spl mu/m gate length.
