摘要： Un sensor de desplazamiento percibe el desplazamiento relativo entre primero y segundo miembros e incluye un alojamiento montado en el primer miembro. Un elemento de imán que tiene primera y segunda puntas de polo se monta al alojamiento. Un sensor de flujo se monta al alojamiento entre las puntas de polo primera y segunda. Un objetivo se monta al segundo miembro para formar una trayectoria de flujo entre las puntas de polo primera y segunda que tiene una reluctancia que varía con el desplazamiento entre los miembros primero y segundo. La disposicion forma una primera trayectoria de flujo disipativo de reluctancia fija a través del sensor de flujo y una trayectoria de flujo primaria a través del objetivo. En una forma el objetivo tiene una superficie configurada para proporcionar una altura de espacio que varía con el desplazamiento. En otra forma el objetivo tiene una superficie configurada para proporcionar una anchura de objetivo que varía con el desplazamiento. El sensor puede utilizarse diferencialmente disponiendo dos de estos sensores.

摘要： An apparatus for sensing the distance between an object (3,4) of electrically conductive material and a reference point has an electrode (12h, 12v), the tip of which constitutes the said reference point. The electrode is connected via a supply line (15h, 15v) to a high voltage source (14) adapted to generate high voltage pulses to provide an arc (16h, 16v) between said electrode tip and said object (3, 4). The apparatus also has an air-cored measuring coil (17h, 17v) disposed around said supply line (15h, 15v) for sensing the electric field about said supply line and transmitting to a measuring signal sensing circuit (18h-25h, 18v-25v) a measuring signal proportional to said electric field. The measuring signal sensing circuit preferably comprises a comparator unit adapted to compare the measuring signal with a signal corresponding to a predetermined distance between the object (3, 4) and the electrode tip.

摘要： The deformation sensitive electroconductive knitted or woven fabric of the present invention is a knitted or woven fabric, which can be changed in electroconductivity at the deformed portion when the deformation of stretch or compression is applied thereon by maintaining at a certain value the ratio of the number of electrically insulating portions to the number of electroconductive portions at the intertwined portions of the fibers and/or the portions between the intertwined portions of the fibers. By using this knitted or woven fabric directly or a deformation sensitive electroconductive sheet having an elastomer laminated on at least one surface of the knitted or woven fabric, the latter can be utilized as a stretch sensitive electroconductive device or pressure sensitive electroconductive device provided with electrodes and capable of detecting the changes in electroconductivity corresponding to deformations as electrical characteristics such as electrical resistance. This deformation sensitive electroconductive device is highly effective in the measurement of large deformations and in durability in repeated use as compared with the pressure sensitive electroconductive device using a pressure sensitive electroconductive elastomer sheet mixed with electroconductive fillers which has been used in the prior art.

摘要： @ Hall-effect position sensor apparatus is disclosed which senses the position of a moving body and provides an output signal indicative of the position of the moving body. The apparatus includes a predetermined number of Hall-effect sensors which are positioned in a straight line and in operating proximity to a moving body made of a ferromagnetic material. A permanent magnet is operatively positioned such that the Hall-effect sensors lie in the magnetic field produced by the magnet while the moving body provides a portion of the path comprising the magnetic excitation circuit with the permanent magnet. The moving body includes portions devoid of ferromagnetic material, which causes a change in the magnetic field. The Hall-effect sensors sense the absolute value of the magnetic field and because of their particular physical alignment and separation, together with the unique interconnection of their individual electrical outputs, provide signals to amplifier devices which represent the second time derivatives of the magnetic field sensed by the Hall-effect sensors. The electrical outputs of the amplifier devices are provided to a Schmitt trigger comparator which performs the analog to digital conversion of the input signals and provides a digital logic output signal which provides a reference point with respect to the location on the moving body, of the void which causes the change in the magnetic field.

摘要： A yoke tyope magnetic transducer head utilizing a magnetoresistance effect in which a magnetoresistance effect sensing portion (5) is provided so as to magnetically couple a cut-away portion in a magnetic circuit including an operation gap (g) and a magnetic yoke (8) having in its one portion the cut-away portion and in which a first bias magnetic field is applied to the magnetoresistance effect sensing portion (5) by a first magnetic flux that is generated when a current is flowed through the magnetoresistance effect sensing portion (5), or when a current is flowed through both the magnetoresistance effect Isensing portion (5) and a bias conductor (3), which includes a hard magnetic layer (14) for generating a second magnetic flux by which a second bias magnetic field is applied to the magnetoresistance effect sensing portion (5) and for passing through the magnetic yoke (8) a magnetic flux which cancels at least a part of the first magnetic flux which passes through the magnetic yoke (8).

摘要： A transducer in the form of a long cable for producing electrical signals in response to mechanical vibration of the cable. The cable comprises an elongate magnetic member (2) and an electrical conductor (3a, 3b, 5a, 5b) extending alongside the magnetic member (2), the electrical conductor (3a, 3b, 5a, 5b) being loosely mounted in the magnetic field of the magnetic member (2) so that mechanical vibration of the cable causes the electrical conductor (3a, 3b, 5a, 4b) to move relative to the magnetic field whereby an e.m.f. and hence an electrical signal is induced in the conductor (3a, 3b, 5a, 5b). The transducer (1) may be used in monitoring or security apparatus.

摘要： A position sensor for sensing the angular position of an oscillatory member such as a transducer, includes a magnetic element (24) which is permanently magnetized in a predetermined direction and forms part of the oscillatory member for oscillatory movement therewith. A Hall plate sensor (36) is positioned adjacent the magnetic element (24) to detect changes in the magnetic field presented thereto by changes in position of the magnetic element. When the magnetic element is oscillated with the transducer, the magnetic field presented to the Hall plate is varied accordingly. This, in turn, produces an electrical signal as an output of the Hall plate which is a function of the instantaneous position of the magnetic element and hence of the oscillatory transducer. That electrical signal may then be used to produce synchronization signals for the imaging apparatus of the transducer.

摘要： A variable reluctance transducer includes a C-shaped assembly (10) defining a magnetic circuit, one limb of the C being longer than the other. The assembly (10) is arranged with its limbs on opposite sides of a movable member (16). A winding (14) linked to the magnetic circuit is connected to a discriminating circuit including an integrator (A, R, C) having a variable bias circuit (D1, D2, R3, R2, C2, C2, A2, R4) which ensures that the peaks of the integrator output are in a predetermined relationship to a reference voltage. A comparator (A3) compares the integrator output with the reference voltage.
