Patent JP-3977744-B2 (JP)
IPC: G10L25/00
Filed: 2002-03-28
Granted: 2007-09-19
Abstract: The present invention proposes a new method and apparatus for the improvement of digital filterbanks, by a complex extension of cosine-modulated digital filterbanks. The invention employs complex-exponential-modulation of a low-pass prototype filter and new methods for optimizing the characteristics of this filter. The invention substantially reduces artifacts due to aliasing emerging from independent modifications of subband signals, for example when using a filterbank as an spectral equalizer. The invention is preferably implemented in software, running on a standard PC or a digital signal processor (DSP), but can also be hardcoded on a custom chip. The invention offers essential improvements for various types of digital equalizers, adaptive filters, multiband companders and spectral envelope adjusting filterbanks used in high frequency reconstruction (HFR) systems.

Abstract: The present invention relates to assay methods used for detecting the presence of PIF, and to PIF peptides identified using this assay. In particular, the present invention relates to flow cytometry assays for detecting PIF. It is based, at least in part, on the observation that flow cytometry using fluorescently labeled anti-lymphocyte and anti-platelet antibodies demonstrated an increase in rosette formation in the presence of PIF. It is further based on the observation that flow cytometry demonstrated that monoclonal antibody binding to CD2 decreased in the presence of PIF. The present invention further relates to PIF peptides which, when added to Jurkat cell cultures, have been observed to either (i) decrease binding of anti-CD2 antibody to Jurkat cells; (ii) increase expression of CD2 in Jurkat cells; or (iii) decrease Jurkat cell viability. In additional embodiments, the present invention provides for ELISA assays which detect PIF by determining the effect of a test sample on the binding of anti-CD2 antibody to a CD2 substrate.

Abstract: A brake lining comprises a lining support plate, an underlayer material and a friction lining. The brake lining is clamped between a pressure plate and a holding fixture, which forms a hole matrix and inside of which electrodes are accommodated. A power supply is connected to the electrodes. The adjacent electrodes have different polarities. A current flow is produced between adjacent electrodes as a result of the different polarities. The field lines extend in the shape of an arch. An arrangement of this type permits the friction lining to be scorched. For hardening, a potential gradient can also be applied between the electrodes and the support plate. The current then flows and the entire friction lining is permeated. This results in a homogenous heating of the friction lining. The invention enables an efficient hardening of the friction lining. It is also possible to conduct a hardening and scorching simultaneously. The invention also enables the friction lining to be pressed during the heat treatment.

Abstract: In a Diesel engine with variably actuated valves, the control cam (9) of each inlet valve (V I ) is shaped so as to provoke the opening of the respective inlet valve (V I ) during the engine's normal exhaust phase to accomplish "internal" exhaust gas recirculation (EGR), i.e. EGR inside the engine, due to the fact that, during the normal exhaust phase, part of the exhaust gas (B A ) passes from the cylinder into the inlet port (I), and then returns to the cylinder during the next induction phase. The engine also comprises means for providing "external" EGR, i.e. EGR outside the engine, and the combination of internal EGR and external EGR is used to control the temperature of the charge induced into the cylinder.
