    Abstract: An apparatus and method of removing fixed pattern noise in a digital camera are provided. The apparatus includes a signal processing unit that calculates location information of the fixed pattern noise from a dark image photographed using an ISO and exposure time that are different from an ISO and exposure time used to photograph a general image, and removes the fixed pattern noise from the general image using the location information. The fixed pattern noise can be effectively removed while reducing the total photographing time in comparison to conventional apparatuses and methods.

    Abstract: Ozone, preferably produced in an ambient air stream passed through a non-thermal hyperplasma reactor, is added to the hot exhaust gas stream from a lean-burn (oxygen-rich) combustion source. The ozone converts much of the NO in the NOx containing exhaust stream to NO2. The resulting NO2/NOx ratio can be controlled by the input energy density to the plasma reactor. Ammonia and/or urea is added to the ozone treated exhaust in proportion to the NOx content, and the stream passed into contact with a reduction catalyst, such as a base metal-exchanged zeolite, to convert the NOx to nitrogen.

    Abstract: A thermistor, which is to be mounted on a PCB, for protecting other circuit elements is disclosed. Electrode patterns separately formed on both surfaces of a film resistance element are respectively shaped into two parts which are engaged to each other with a non-conductive gap interposed therebetween. Thus, a Tombstone phenomenon caused by asymmetric structure may be fundamentally prevented. Grooves are formed in both sides of the thermistor, and connection portions for electrically connecting the electrodes formed on both surfaces of the thermistor are formed through the inside of the grooves or through the sides except the grooves. Thus, though a crack arises in the connection portion, it is possible to prevent the crack from being propagated to the entire connection portion along the side of the thermistor.

    Abstract: A method for producing the reciprocal of an arbitrary element in a finite field GF(2.sup.n) having a primitive element, the reciprocal of the primitive element and an identity element for multiplying. The method includes the steps of comparing the arbitrary element with the identity element of multiplying; producing the identity element of multiplying as the reciprocal of the arbitrary element, provided that the arbitrary element is the same as the identity element; recursively multiplying it by the primitive element by the identity element so as to produce a first element, and recursively multiplying the identity element by the reciprocal of primitive element so as to produce a second element, until one of the first and second elements equals the arbitrary element, provided that the arbitrary element is different from the identity element; and producing the second element as the reciprocal of the arbitrary element if the first element equals the arbitrary element, and producing the first element as the reciprocal of the arbitrary element if the second element equals the arbitrary element.

    Abstract: A gate driver comprises a shift register that has a plurality of stages connected together and outputs a gate signal comprising a first pulse and a second pulse to a gate line. A stage includes a holding part, a pre-charging part, a pull-up part, and a pull-down part. The holding part discharges an output terminal to an off-voltage in response to a first clock signal. The pre-charging part turns off the holding part and outputs the first clock signal as the first pulse to the output terminal in response to an output signal of a previous stage. The pull-up part outputs a second clock signal as the second pulse to the output terminal in response to the output signal of the previous stage. The pull-down part discharges the first output terminal to the off-voltage in response to an output signal of a next stage.
