Title: Derivation of Steady Values of Blood Pressures
IPC: G06F17/00
Filed: 1979-04-05
Abstract: Apparatus for deriving an average of data points in which the contribution of each data point to the average is generally inversely related to the difference between its amplitude and the amplitudes of a few previous data points. Electrical signals representing blood pressure are directed to means 7 for determining the amplitude of the most recent maximum peak SMAX and the amplitude of the most recent minimum peak DMIN (as well as signals indicating when SMAX and DMIN have attained the values to be processed). The SMAX signal is measuring circuit wherein a moving average of the previous recent maximum peaks is determined in such a way as to give greater weight to those peaks having an amplitude closer to the average amplitudes of their predecessors than to those having significantly different amplitudes. The resulting "steady" value of the systolic pressure is displayed on an indicator 50. The DMIN signal is processed in a similar way in a diastolic pressure circuit 58. A digital version of the Fig. 7 embodiment is also disclosed. <IMAGE>

Title: Focal plane photographic camera shutter
IPC: G03B9/34
Filed: 1979-06-28
Abstract: In an aerial reconnaissance photographic camera, the exposure aperture 15c of a revolvable focal plane shutter blind 15 is varied by varying the relative positions of an outer part 15a and an inner part 15b of the blind 15. Two helical driving gears 22 and 23, of opposite hand to each other and fixed on a common shaft 24, respectively drive helical gears 19 and 21 (also of opposite hand to each other) the gear 19 driving outer blind part 15a through one pulley and belt system 17a1, 16a and 17b1, 16b, the gear 21 driving inner blind part 15b through another pulley and belt system 17c1, 16c and 17d1, 16d. Axial displacement of shaft 24 produces relative rotation between gears 19 and 21 and hence variation of aperture 15c. The shaft 24 is rotated at a speed directly proportional to aircraft speed and inversely proportional to aircraft height, with the result that the frequency of the exposures is variable, and the shaft 24 is displaced axially according to its speed (to compensate for the speed of the shutter by varying the aperture) and according to the light conditions. <IMAGE>

Title: Oxygen-generating Apparatus
IPC: A62B21/00
Filed: 1979-11-21
Abstract: A chemical oxygen-generating apparatus has a container (2) provided with an outlet (10) and a chemical filling (3) capable of generating oxygen within the container (2). A sheet-form member (13) is secured to the container (2) to close off the outlet (10) and is deformable from an initial configuration under the influence of a predetermined pressure within the container (2). Puncturing means (17) for puncturing the sheet-form member (13) upon deformation is also provided. In use, the chemical filling (3) generates oxygen and the resultant increase in pressure in the container (2) deforms the sheet-form member (13) until it is punctured by the puncturing means (17), whereupon oxygen flows out through the outlet (10). The sheet-form member (10) provides a secure seal which, in use, is automatically punctured, thereby ensuring that no dangerous build-up of pressure occurs in the container (2). <IMAGE>
