摘要： A system and method of delivering fiber optic communication service is provided. The method includes monitoring a strain signal generated by a strain-sensing optical fiber embedded in a roadway. The method includes comparing the strain signal to a predetermined allowable strain threshold of an optical communication cable associated with the strain-sensing optical fiber. The method includes relieving strain at a position along a length of the optical communications cable when the strain signal is determined to exceed the predetermined allowable strain threshold.

摘要： A torque detecting apparatus includes a first shaft; a second shaft; an elastic member coaxially linking the first and second shafts; and a magnet attached to the first shaft; a pair of magnetic yokes composed of a first magnetic yoke and a second magnetic yoke, the first and second magnetic yokes being fixedly installed on the second shaft; and a magnetic sensor. Each magnetic yoke includes an opposing portion and a wall portion. The opposing portion is opposed to the magnet and displaced circumferentially relatively to the magnet when the elastic member is subjected to a torsional displacement.The wall portions of the first and second magnetic yokes are separated and positioned outside the opposing portions in the radial direction. The wall portions of the first and second magnetic yokes extend to be mutually opposed. The magnetic sensor is positioned between the wall portions.

摘要： A sensor operates to produce a differential signal with a voltage regulated that generates a regulated voltage to a first sensor element for detecting a physical parameter. A current mirror circuit is configured to provide a first sensor current to the first sensor element, detect the first sensor current at the first sensor element and duplicate the detected current to provide a second sensor current to a second sensor element. The second sensor element detects the physical quantity with the replicated current.

摘要： A circuit for obtaining information on a physical quantity according to an embodiment includes a sensor arrangement sensitive to the physical quantity, at least one further sensor element sensitive to the physical quantity and a supply circuit configured to provide the sensor arrangement with a supply signal comprising a supply voltage controlled by the supply circuit in a closed-loop configuration. The supply circuit is further configured to provide the at least one further sensor element with a further supply signal comprising a further supply current such that a magnitude of the further supply current fulfills a predetermined relationship with a magnitude of a supply current of the supply signal. As a consequence, it may be possible to improve a trade-off between an improved compensation of variations, simplifying an implementation, simplifying the manufacturing, simplifying the sensing and providing stable sensing conditions.

摘要： A method for controlling a vapor compression system determines a value of a metric of performance of the vapor compression system using a previous value of an estimated parameter and a previous value of a control signal determined for a previous time step of the control. The values of the estimated parameter represent a relationship between values of the control signal and values of the metric of performance. A current value of the estimated parameter is determined based on the previous value of the estimated parameter and an error between the determined value of the metric of performance and a measured value of the metric of performance. Next, a current value of the control signal is determined based on the current value of the estimated parameter.

摘要： A stroke amount detecting device includes a magnetism detecting unit, a first magnetic field generating unit and a second magnetic field generating unit. A magnetic pole of the first generating unit and a magnetic pole of the second generating unit, which are opposed to each other, have different polarities. A distance between a gap end of the first generating unit and a gap end of the second generating unit, which are located on a farther side of a rectilinear axis, is smaller than a distance between an open end of the first generating unit and an open end of the second generating unit, which are located on a closer side of the rectilinear axis. The magnetism detecting unit detects a stroke amount of an object based on a magnetic flux generated between the open end of the first generating unit and the open end of the second generating unit.

摘要： An in-vehicle electronic control unit (ECU) for correcting an error introduced to a sensor output signal as a result of amplification is provided. An output voltage of first and second voltage generators and after-amplification voltages of such output voltages are respectively A/D converted for input into a linear function. A microcomputer adjusts the output voltage of the first and second voltage generators which are amplified by the amplification circuit so that the output signals of the first and second voltage generators are adjusted to increase a voltage difference between the two. The increased voltage difference allows accurate identification of the linear function and removal of the error that is introduced to the sensor output signal during the course of processing by the amplification circuit.
