Abstract: PURPOSE: Method and apparatus for non-invasive, cuffless, continuous blood pressure determination are provided. CONSTITUTION: Arterial blood pressure of a subject is determined by detecting the EKG for the subject and selecting a fiducial point on the EKG during a pulse. Apparatus is provided for monitoring blood volume versus time at a selected location on the subject's body such as a fingertip. A time difference between the occurrence of the selected fiducial point on the EKG and a selected change in blood in volume at the selected body location is determined. This time difference depends on the arrival time of the pulse at the distal location in addition to the shape of the blood volume versus time curve. Heart rate is determined from the EKG. The arterial pressure is computed from pulse arrival time, volumetric wave shape and instantaneous heart rate for each pulse. It is preferred that the fiducial point on the EKG be an R-wave. A suitable method for determining change in blood volume utilizes photoplethysmography. Methods are disclosed for determining diastolic pressure, systolic and mean arterial pressure. In another aspect, artifact detection and rejection enabled.

Filed: 2000-01-26
Abstract: PURPOSE: A nozzle structure of a steam generator having a low water level operational reliability is provided to maintain a water level of a cooling system as high as possible and smoothly obviate problems of a dynamic support structure. CONSTITUTION: An angle of a nozzle(210) on an outlet side is 40° on the basis of a bottom surface of a tube sheet. By varying the angle of the nozzle(210) installed on the outlet side of a steam generator(200), a water level is maximized according to a requested low level operation. An interference between a suction line of a cooling pump and a vertical column of an RCP pump support structure is minimized while the minimum water level is increased. As width of the vertical column of the reactor cooling pump support structure is reduced by 4 inches, thickness is increased by 1.5 inches. Accordingly, strength of the reactor cooling pump support structure is not changed. In this condition, if a water level is decreased, a water level is maintained to be much higher than that in the conventional apparatus. In addition, nozzle dams can be easily installed on an inlet of the steam generator and an outlet of the steam generator. In order to install the nozzle dams, first the water level is reduced to a mid-loop level, manways which is disposed on both sides of the steam generator are opened and then the nozzle dams are installed.

     본 발명 타이어 보강용 스틸코드의 제조 방법은, 하연을 구성하는 강선을 n 1 개의 심선과 n 2 개의 외주선으로 구분하여 n 1 개의 하연 심선과 n 3 개의 상연용 강선은 연선기 내에서 공급하고, n 2 개의 하연 외주선은 연선기 외부에서 공급하면서 n 2 개의 하연 외주선이 n 1 개의 하연 심선 외주면에 1차 꼬여지도록 한 후, 상기 n 3 개의 상연용 강선이 하연 외주선과 동일한 피치 길이와 동일한 피치 방향으로 하연의 외주면에 꼬여지도록 연선함을 특징으로 한다. 
     본 발명 스틸코드의 (n 1 +n 2 ) 하연 구조는 하연을 구성하는 연선 작업시 외주선의 이탈이 방지되는 안정된 꼬임 구조로서 타이어 등의 고무 보강재로 사용시 안정된 시효 접착력을 보여 타이어의 내구성을 향상시켜 줄 뿐만 아니라, 연선기 내·외부에서 공급되는 하연용 강선들이 연선된 상태가 아닌 강선 그대로 공급되기때문에 기연선된 하연을 공급하는 종래 제조 방법과 달리 한 대의 연선기에서 스틸코드의 제조가 가능하기 때문에 생산성을 높일 수 있는 이점이 있다.
