Patent ES-444711-A1 (ES)
Title: Acoustic method for measuring gas pressure
IPC: G01L11/00
Filed: 1976-01-28
Abstract: A non-destructive acoustic method for measuring gas pressure in a hermetically sealed enclosure. In accordance with the method, an acoustic signal is generated and transmitted through the gas medium within the enclosure. The acoustic impedance mismatch between the enclosure and the gas medium is dependent upon the pressure of the gas and correspondingly affects the transmissivity of the acoustic signal. The signal is received after traversing a given travel path through the gas and converted into a corresponding electrical output calibrated against a standard to provide a direct measure of the pressure of the gas within the enclosure. In the preferred arrangement, the enclosure is acoustically damped to substantially dissipate acoustic energy traveling within the enclosure walls.

Title: Apparatus and Method for Detecting Electrocardiogram Baseline Shift
IPC: A61B5/308
Filed: 1979-02-26
Abstract: An apparatus for detecting baseline shift in an ECG system, in which there is a multiple element electrode (15, 16) at a given skin location and another such electrode (17, 18) at another skin location, each providing an ECG signal of negligible magnitude between the elements because of the close spacing while the pair of elements are sufficiently separated so that the motion of one element is at least partially independent of the motion of the other. Parallel ECG signals (22, 24) are obtained from different elements of two multiple element electrodes and which under normal operating circumstances would be equal. Any difference between the signals (due perhaps to an electrode becoming dislodged) is detected by logical circuitry (25, 26, 27) to produce a signal on line 26 indicating baseline shift. The baseline shift signal on line 26 will prevent the e.c.g. signal utilizing means from giving a false alarm or output.
