摘要： A test pattern generating apparatus for generating test patterns to test a sequential circuit having at least one memory element. The apparatus calculates, in response to a primary input applied to the sequential circuit, analog logic values for signal lines in the sequential circuit using a nonlinear function, then stores history data for the analog logic values with an inverse covariance matrix of the analog logic values. The apparatus then calculates an evaluation value according to the degree of variance between the analog logic values and the history data. A primary input setting unit is used for producing a next primary input which provides a maximum evaluation value from the evaluation value obtained from the present primary input. inputs produced by the primary input setting unit.

摘要： A method of controlling a mechanical ventilator is provided which is capable of increasing a stability margin in the controlling of a gas-delivery mechanism for the mechanical ventilator. The flow rate F of an assisting gas is measured, and an observer 54 estimates a flow rate {circumflex over (F)} of the assisting gas. A difference ΔF between the measured flow rate F and estimated flow rate {circumflex over (F)} is then determined, and information on a patient's respiratory effort pressure Pmus is obtained. A target pressure Pin for controlling a gas-delivery mechanism 20 is calculated on the basis of this information. When the target pressure Pin is calculated on the basis of the flow-rate difference ΔF, an allowance with respect to the stability limit of the overall system 14 can be increased. This enables the runaway to rarely occur even when an actual overall system is varied. Moreover, the responsibility of assist respiration can be improved as compared with that of the related art PAV method.

摘要： The invention is directed to a vehicle passenger restraint system having a restraint device for protecting a passenger in a vehicle. The system includes an acceleration sensor for sensing an acceleration of the vehicle, and an A/D converter for converting an output of the acceleration sensor into a digital signal indicative of the acceleration of the vehicle. A wavelet transform processor transforms the output of the A/D converter by a wavelet function into a wavelet coefficient. The wavelet function is provided on the basis of a mother wavelet function localized in time, scaled in response to a scale parameter, and shifted in response to a shift parameter indicative of a time localization. A speed variation computing unit sets a first condition when the wavelet coefficient transformed by the wavelet transform processor exceeds a predetermined value, and integrates the output of the A/D converter for a predetermined period to provide a speed variation. And, an actuator sets a second condition when the speed variation provided by the speed variation computing unit exceeds a predetermined level. Then, the actuator actuates the restraint device when both of the first and second conditions are set. The wavelet transform processor may be performed in accordance with the Infinite Impulse Response.
