108results about How to "Little degradation" patented technology

Digital camera and method of controlling the same

The present invention is directed to obtaining an image having predetermined brightness, while making the degradation of the image as little as possible. A distance (an irradiation distance d) at which a predetermined amount of reflected light can be obtained is obtained from the guide number Gn of a strobe and the f-stop value F (the focal distance f of a zoom lens). When the strobe is used, it is judged whether or not a subject is positioned within the irradiation distance d. When the irradiation distance d of the strobe is shorter than the distance to the subject, that is, the subject is beyond the irradiation distance d of the strobe, an imaging signal is amplified than usual.

Control apparatus and control method for internal combustion engine

ActiveUS20140020363A1Reduce the sense of strangeness causedAlternationElectrical controlInternal combustion piston enginesEngineeringInternal combustion engine
An engine ECU diagnoses the presence or absence of abnormality during execution of the fuel cut. The engine ECU is configured to restrict the fuel cut according to the temperature of a catalyst when the temperature is higher than a fuel-cut-restriction temperature of the catalyst. The engine ECU is configured to set the fuel-cut-restriction temperature is lower when the diagnosis has been completed than when the diagnosis has not been completed. Furthermore, the engine ECU continues the fuel cut if the diagnosis is completed during execution of the fuel cut while the temperature of the catalyst is between the fuel-cut-restriction temperature set prior to the completion of the diagnosis and the fuel-cut-restriction temperature set after the completion of the diagnosis.

The present invention relates to a reactive silicone composition comprising: (A) an alkenyl group-containing organopolysiloxane represented by the average unit formula; (B) an alkenyl group-containing organopolysiloxane represented by the general formula; (C) a silicon atom-bonded hydrogen atom-containing organopolysiloxane represented by the general formula; (D) a hydrosilylation reaction catalyst; (E) a white pigment; and (F) non-spherical silica, spherical silica or glass fibers, a reactive thermoplastic article obtained by the composition to reaction under specified conditions, a cured product obtained by heating the article, and an optical semiconductor device having the cured product. The reactive silicone composition is a solid at an ordinary temperature and gives a reactive thermoplastic article that is fluidized at elevated temperatures. The reactive thermoplastic article is once fluidized upon heating and then gives a cured product. The cured product exhibits little reduction in mechanical strength or discoloration caused by heat or light and has high light reflectance. And the optical semiconductor device exhibits high luminous efficiency and causes little thermal degradation or photodegradation of a light reflection material.

Digital radio processor architecture with reduced dco modulation range requirement

A method of achieving reduced modulation range requirement in a Digitally Controlled Oscillator (DCO) which is deployed as part of a DRP (Digital Radio Processor) and tuned to a tuning frequency range having operating-channel center-frequencies, wherein phase difference between consecutive samples is termed as FCW (Frequency Control Word), uses the steps of digitally modifying and limiting the FCW so that the FCW does not exceed known FCW thresholds, e.g., chosen from π / 2, π / 4, π / 8, and redistributing the FCWs while maintaining a cumulative sum of phases and without significant EVM (Error Vector Magnitude) degradation. The FCW threshold can be chosen arbitrarily and need not be in the form of π / 2n. The method uses a FCW limiting algorithm which reduces supply voltage sensitivity of the DCO and enables significant reduction in area of capacitor bank which would be otherwise needed.
