An injection control method for controlling a 'common rail' fuel injection system in a diesel engine is described. The method includes the following steps: an initializing step for acquiring engine control parameters; and a main adjustment cycle for adjusting operational variables of the engine. The injection control method also includes an interrupting step for adjusting an injection procedure proper of the injection system by variation of all the characteristic parameters of the injection procedure. Also described is an injection control system for a diesel engine based on the above method.

A blood pressure Holter system includes a pneumatic constriction sleeve to be worn on an arm of the user and includes a first sensor for acquiring systolic and diastolic values of arterial pressure of the user. A second sensor is carried adjacent a chest of the user for sensing movement of the user's body. The system further includes a detection and classification circuit for detecting and classifying movement of the user's body for producing an index of a state of physical exertion corresponding to systolic and diastolic values of arterial pressure. A fuzzy logic controller processes the systolic and diastolic values of arterial pressure using fuzzy logic.

A portable system carried by a user for assessing movement of the user includes at least one motion sensor adjacent a portion of the user's body under observation. An analog-to-digital converter is connected to the motion sensor for converting an analog signal therefrom into a digital signal. A logic circuit is connected to the analog-to-digital converter for calculating parameters based upon the digital signal. A first fuzzy logic processing circuit is connected to the logic circuit for processing the calculated parameters and for generating corresponding fuzzy classification labels based upon movement of the portion of the user's body under observation during an interval of time. A memory is connected to the first fuzzy logic processing circuit for storing at least one of the calculated parameters and the fuzzy classification labels. A second fuzzy logic processing circuit is connected to the memory for generating an activity index representative of the movement of the user during the interval of time based upon the fuzzy classification labels.

A method of assessing the neuro-psycho-physical condition of a person includes acquiring, by a self-contained hand held instrumentation, reaction times, execution times and ergometric data of actions performed by the person carrying out a certain test. This test includes processing the time data and the ergometric data for calculating the power exerted in performing each action. Data on the reaction time and the exerted power is processed on the basis of certain software to produce information on the neuro-psycho-physical condition. The ergometric data and reaction time data are processed by a fuzzy logic processor. The hand held instrument may optionally include also motion and voice articulation classifiers.
