Abstract: In a memory cell, the drive current capabilities of the transistors may be adjusted by locally providing an increased gate dielectric thickness and/or gate length of one or more of the transistors of the memory cell. That is, the gate length and/or the gate dielectric thickness may vary along the transistor width direction, thereby providing an efficient mechanism for adjusting the effective drive current capability while at the same time allowing the usage of a simplified geometry of the active region, which may result in enhanced production yield due to enhanced process uniformity. In particular, the probability of creating short circuits caused by nickel silicide portions may be reduced.

Abstract: A system to monitor the temperature of an integrated circuit and to dissipate heat generated thereby includes a heat sink to overlie the integrated circuit. A temperature sensor is located on the heat sink to detect the temperature adjacent the integrated circuit. Temperature signal conditioning circuitry is responsive to the temperature sensor and generates a temperature alarm signal when the temperature at the integrated circuit reaches a threshold level. A fan overlies the heat sink and draws air across and then away from the heat sink to cool it. A pressure transducer is mounted on the fan and detects air flow through the fan. Pressure signal conditioning circuitry is responsive to the pressure transducer and generates a pressure alarm signal when the air flow through the fan falls below a threshold level. Alarms are triggered by the temperature and pressure alarm signals to warn a user.

Abstract: Disclosed is a fire detection and engine monitoring system of the type which utilizes a pair of elongated thermistor strands extending over substantially the same path to provide redundancy. A resistance of the two thermistor strands are sensed and a resistance difference signal is generated.

Such differences are indicative of the deterioration over time of the condition of one of the sensors.

Abstract: A fluid level sensor utilizes thick film thermistors in a four-thermistor bridge configuration. The bridge is heated by a heater to sense the presence or absence of fluid at a particular level with respect to the thermistors. Upon energizing the bridge with a power source, the middle leads thereof are monitored for voltage separation and polarity. An indicator circuit indicates when one or more of the thermistors is submerged in the fluid. The heater influences the temperature of the thermistors to a greater or lesser extent depending upon whether or not they are submerged. Detectable changes in voltages across the bridge are accordingly produced.

Abstract: An alarm circuit for detection of an overheated condition comprises a bridge rectifier or a battery to provide a d.c. input, and a detector bridge including a thermistor and Zener diode in adjacent arms. The diode is set to operate along that portion of the thermistor response curve which is slowly changing. Hence, the Zener diode will be activated if the thermistor detects at the very onset of an overheated condition. Bridge unbalance is fed to an operational amplifier which activates a transistor to turn on an alarm such as an audio indicator, LED, telemetry system, etc. The alarm circuit has application for detection of a line overload, as a monitoring device for patients and for persons undergoing physical activity such as joggers and the like. By sounding an early alarm, overheating in a line wire caused by say, an overheated appliance, can be corrected with a consequent energy saving and minimizing damage to the appliance.

The circuit comprises low-pass filtering means, preferably comprising an active filter, for removing the AC component of the transducer output signal representing the fluctuating component of the measured parameter, to produce a DC output signal representing the steady state component of the measured parameter; and subtracting means for subtracting the DC component from the transducer output signal to produce an AC output signal representing the fluctuating component of the measured parameter. The circuit is thus capable of producing simultaneous outputs representing separately the steady state, fluctuating, and combined components of the transducer output signal, with the introduction of little or no phase error.
