摘要： A two-terminal integrated circuit magnetic-field detector, for use in detecting a low level of a liquid in a vehicle, has a Hall element, a Schmitt type comparator, an anti-sloshing accumulator such as an up-down counter, and a latching driver all connected in tandem. The anti-sloshing accumulator is for producing a signal that is the integral as a function of time of the binary comparator output signal. During sloshing, when the average liquid level is near that at which a low-level warning signal is desired, the accumulator signal climbs in a vacillating manner. The latching driver is connected across the two integrated circuit (I.C.) terminals and latches on when the accumulator signal reaches a predetermined value, dropping the impedance across the two I.C terminals. A liquid level indicating lamp is connected in series with a source of DC voltage and the two I.C. terminals, so that when the average position of the floating magnet approaches that of the I.C. detector, the driver latches on and the low-level indicating lamp is also turned on and cannot be turned off except by removing the DC energizing voltage. The accumulator may be an up-down counter with means for preventing counting in the over-flow mode, and also for preventing counting in an under-flow mode, namely downward counting below zero count.

摘要： A low power magnetic-field detector, of the kind for detecting an ambient magnetic field that is greater than a predetermined field strength, is comprised of a Hail element, a transducer-voltage amplifier, and a zero-crossing comparator, all connected in tandem. A clock and switch are used to chop the energizing current to the Hall element. Alternatively, the amplifier and comparator are also chopped to further reduce power consumption. A clockable flip flop is synchronously enabled for an instant at the end of each period of energizing the Hall element. The comparator output signal is transferred to the flip flop Q output and held there during each period of not energizing the Hall element. A Positive-feedback hysteresis circuit adds a bias voltage to the amplified Hall voltage and is applied to the comparator input to effect comparator hysteresis with memory covering clock-period portions when the Hall element is not energized. The comparator is thus transformed into a Schmitt trigger circuit having hysteresis memory, making it possible to chop the Hall element to substantially reduce the detector power consumption without loosing the hysteresis feature.

摘要： A magnetic field sensor assembly has a magnet, a semiconductor sensor and a metal leadframe encapsulated in a plastic package to form a semiconductor integrated circuit. A metal leadframe has a die attach pad on which the sensor is secured and an assembly having one or more projections for securing the magnet in close proximity to the sensor. The leadframe is made from a metal having sufficient spring tension so that the assembly having the projections will secure the magnet. The sensor is adjacent to a ferromagnetic object and will detect a change in magnetic field caused by the ferromagnetic object. Only a thin layer of the plastic package covers the sensor thus reducing the distance between the sensor and the ferromagnetic object but still maintaining an air gap between the plastic package and the ferromagnetic object sufficient to allow passage of the ferromagnetic object.

摘要： Disclosed is a rotation detecting sensor suitable for use under a vibration-abundant condition as e.g. a sensor disposed in an automobile body for detecting rotation of an engine or ABS. The sensor includes a detecting element for detecting rotation of a rotary body as a change in a magnetic flux and outputting a signal and an integrated circuit for processing the amplified signal into a pulse corresponding to the detected rotation of the rotary body. The signal processing includes an initialization such as a gain adjustment for obtaining an appropriate gain for use in the subsequent process of conversion of the amplified signal to the pulse. According to this invention, a re-initialization is effected to obtain a new initial value such as a new gain if the previously effected initialization is determined inappropriate.
