摘要： There is provided a method of arranging a security alarm system on a window/door and framing. The system includes an object and a sensor which is capable of detecting the object within a predetermined range. The method includes positioning a first of the sensor and object on a first of the window/door and framing. The method includes opening the window/door to a threshold distance which facilitates ventilation and inhibits an intruder from passing through the window/door. The method includes positioning a second of the sensor and object along a second of the window/door and framing such that the sensor is able to detect the object as the window/door is opened up to but not past the threshold distance.
There is also provided in combination, a window/door, framing extending about the window/door and a security alarm system coupled to the window/door and framing in the manner described above.-

摘要： A field detector (2) comprises a field-responsive element (10) which undergoes a dimensional change when exposed to a predetermined field; and an interferometric read-out arrangement arranged to detect the dimensional change of the field-responsive element. A light source (4) is arranged to provide a measurement beam reflected from the field-responsive element (10) and a reference beam not reflected from the field-responsive element (10), an optical detector (6) being disposed so as to detect at least part of an interference pattern produced by the measurement beam and the reference beam. The field-responsive element (10) has a shape comprising a curved surface and is constrained at least one edge (12) thereof such that the dimensional change causes the curved surface to be displaced in a direction which changes an optical path length of the measurement beam relative to the reference beam, thereby changing the interference pattern detected by said optical detector.

摘要： A nanodevice provides for electric-field control of magnon-QSD interactions. The nanodevice includes a ferroelectric substrate, a ferromagnetic material disposed over the ferroelectric substrate, and a nanodiamond including an ensemble of nitrogen-vacancy (NV) spins, each NV magnetically interfacing with the ferromagnetic material. An electric field is measured by applying a voltage across the ferroelectric substrate and the ferromagnetic material, changing a magnon excitation spectrum of the ferromagnetic material with respect to an electron spin resonance frequency of the ensemble of NV spins, and measuring a relaxation rate of the ensemble of NV spins.

摘要： In a marker detection method in which a sensor unit (11) that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers (10) laid in a road, a feature value that represent symmetry of magnetic distribution, which is the distribution of magnetic measurement values obtained by each magnetic sensor included in the sensor unit (11) is generated, and threshold process regarding the feature value is executed to determine the possibility of the presence of magnetic generation source other than magnetic marker (10), that causes disturbance, and hence to suppress erroneous detection.

摘要： A target value of magnetic flux density and magnetic flux density actually obtained are made to coincide precisely with each other. An electromagnet control device comprises a current value determining unit for determining, based on a magnetic flux density instruction value, a value of current that is made to flow through a coil. The current value determining unit is constructed to execute a second process for determining, based on a second function, a value of the current, if the magnetic flux density is to be decreased from that in a first magnetization state, and a fourth process for expanding or reducing the second function by use of a first scaling ratio for transforming it to a fourth function, and determining, based on the fourth function obtained after above transformation, a value of the current, if the magnetic flux density is to be decreased from that in a third magnetization state.

摘要： A system includes a magnetic field sensor arrangement and a controller. The magnetic field sensor arrangement includes a first sensor chip having an integrated circuit differential magnetic field sensor circuit configured to generate a first output signal comprising first signal pulses, a second sensor chip having an integrated second differential magnetic field sensor circuit configured to generate a second output signal comprising second signal pulses, and at least one output signal terminal configured to output the first and the second output signals. The controller receives the first and the second signal pulses from the at least one output signal terminal, evaluates the first and the second signal pulses, and detects an error of an operation of the magnetic field sensor arrangement in response to the first and the second signal pulses not satisfying an expected output pattern of the first and the second signal pulses.
