Abstract: An automated sphygmomanometer in which the so-called "air effect" (a slow rise or fall in cuff pressure caused by step inflates or deflates) is substantially eliminated by deflating (inflating) the pressure cuff to a pressure lower (higher) than the target pressure, waiting a short time interval, and then inflating (deflating) the pressure cuff to the target pressure. The driving force that causes the air effect to settle out after a step inflate or deflate is proportional to the size of the step change in pressure and is thus greatest during the wait time before the pressure cuff is inflated or deflated to the target pressure. Once at the target pressure, the remaining air effect is counteracted by the incremental air effect introduced by the latter inflate or deflate so that the air effect cancels out. The techniques of the invention provide most improved results for large inflates and deflates of 20mm Hg or more or first deflates after a complete inflate of the pressure cuff where the air effects are most pronounced.

Abstract: The computer unit has an arrangement (MUS) for speech recognition independent of the speaker. A phoneme record memory (PS) stores phonemes and/or phoneme characteristic vectors for phonemes which have any desired number of segments. The vectors each characterise a phoneme. A user memory (BS) stores phoneme trains of digitised words, or digitised words spoken into the computer by the user. The phoneme trains are derived from a device which compares user characterising vectors with the stored phoneme vectors. The comparator (MV) compares user vectors of part of a digitised speech signal, which characterise that part of the signal, with the stored phoneme vectors. To form digitised speech signals from phonemes, the signal is divided into a number of digital speech signal components. For each component, a user characterising vector is derived which characterises the signal component. It is compared to stored phoneme vectors to provided a similarity value. The value is stored and in dependence on the value a train of phonemes is derived for the digitised speech signal from which the signal is composed.
