Title: Sense amplifier with hysteresis
Inventor: BARCELLA ANTONIO
IPC: G11C17/00
Filed: 1995-05-08
Abstract: PURPOSE: To ensure noise immunity, and to inhibit the occurrence of spurious output transition by connecting an inverting amplifying stage formed by a single transistor between the output node of a differential input stage and an intermediate node thereof. CONSTITUTION: When an output at a differential stage is under a high state, a transistor M8 is tuned on, and switches an output level from the high state to a low state. On the other hand, the gate voltage of the transistor coincides with a voltage drop crossing a transistor M5. The transistor M2 of forward feedback is conducted at the time of the high state of the output at the differential stage. A transistor M9 can flow a sufficient current for the generation of the turn-off of the transistor M8 by beforehand specifying the dimensions of the transistors M2, M5, M8 at that time. Accordingly, noise immunity is ensured, and the occurrence of spurious output transition can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To precisely estimate the driving rhythm of a driver by providing an operating condition judging means which determines whether or not the driving condition of the driver has worsened through the comparison of a calculated steering angle speed distribution and the calculated frequency of steering control with preset references.

Driving time is measured based on the driving time measured with a counter 15, and the degree of physical fatigue is calculated form cumulative driving time. Next, the current steering angle speed distribution and the current frequency of steering control are averaged, and the degree of modulation of driving rhythm is calculated using the reference values of the steering angle speed distribution and of the frequency of steering control that are taken during the initial period of driving. Finally, the degree of modulation of the driving rhythm and the degree of physical fatigue are vector synthesized to calculate the degree of necessity to recommend safe driving, which is compared with a preset reference value for the recommendation of safe driving to determine whether or not the driving condition of the driver has worsened.
