摘要： Tunable electronic units and associated systems, as well as methods for tuning characteristic properties of soft electronic units (e.g., inductance, capacitance, and resistance) and fabricating soft tunable planar inductors, axial inductors, capacitors, and resistors, are provided. Disclosed systems and methods enable standardized tuning of different types of soft electronic units (e.g., including a soft inductor, capacitor, and resistor, etc.), and enable remote tuning while maintaining a tuned value without expending power. In certain embodiments, electrical properties of the soft electronic units are tuned using a mobile component (e.g., ferrofluid and iron powder) dragged with a permanent magnet inside a soft fluidic channel. This may be used for applications and devices which need to be soft and flexible, such as implantable electronics, wearable devices, and skin electronics.

摘要： A frequency-dependent resistance element includes an element assembly composed of a sintered magnetic material and a coil conductor embedded in the element assembly. The sintered magnetic material is composed of a primary component containing Fe, Zn, Ni, and Cu and a secondary component containing Co. In the primary component, on a percent by mole basis, the Fe content is 46.79 to 47.69, the Zn content is 12.60 to 24.84, and the Ni content is 19.21 to 32.36 in terms of Fe2O3, ZnO, and NiO, respectively. The molar ratio (Ni:Zn) of Ni to Zn is (1−X):X, where X is from about 0.28 to about 0.56. The content of Co in terms of Co3O4 is 1.0 to 10.0 parts by mass relative to 100 parts by mass of the primary component containing Fe, Zn, Ni, and Cu in terms of Fe2O3, ZnO, NiO, and CuO, respectively.

摘要： This invention discloses a type of noncontact linear potentiometer; the potentiometer comprises a slider, a rotating shaft, a guide rod, a tunneling magnetoresistive sensor, a permanent magnet, a printed circuit board, and two support structures. In this configuration the slider moves along the guide rod and the rotating shaft, causing the rotation of the rotating shaft; the permanent magnet is attached to an end of the rotating shaft, and it therefore rotates as the shaft rotates. A tunneling magnetoresistive sensor is located adjacent to the permanent magnet, soldered onto a printed circuit board, and it is used to measure the angle of rotation of the permanent magnet. The guide rod constrains the sliding direction of the slider, and the two support structures are located at the opposite ends of the guide rod and rotating shaft, and they are used to support the rotating shaft and guide rod. Located between the slider and rotating shaft is a ball bearing, a pin and a leaf spring assembly. This potentiometer has several advantages, including a compact structure, easy fabrication, long service life, in addition to providing smooth slider motion that provides a pleasing user experience.

摘要： A dual magnet Hall effect switch for contactless switching is provided. The Hall effect switch includes a magnet carriage and a Hall effect sensor positioned inside a switch housing. The magnet carriage includes two magnets positioned with opposite polarities facing the Hall effect sensor and in contact. When the switch is actuated, the magnet carriage is displaced within the switch housing and relative to the Hall effect sensor. The two magnets positioned inside the magnet carriage are also displaced. The positional displacement of the magnets relative to the Hall effect sensor alters the magnetic field detected by the Hall effect sensor. When the magnetic field detected by the Hall effect sensor reaches a predetermined level, the switch is actuated. The Hall effect switch also includes a boot seal sealing the switch and an internal clicker ball to provide an audible or tactile indication of the switch's actuation.

摘要： A lever (14) is fixed to a shaft (15) which can be connected to a rotation shaft (19) of a device such as a potentiometer. The shaft (15) is journaled in a pair of support plates (10, 11) which are rigidly connected to one another, and brake discs (23) having brake linings (22) are arranged between the lever (14) and the support plates (10, 11). Cup springs (24) provide a spring force acting transversely to the operational direction of the lever (14), so that frictional forces provided by the brake linings (22) assure a smooth and jolt free operation of the lever (14).

摘要： A resistor card for a potentiometer to measure the fuel in a fuel tank consists of a non-conductive substrate with a plurality of elongate conductive contacts deposited. The contacts have an elevation above the surface of the substrate and the contacts are oriented in parallel relationship to each other to form a wiper track across which a wiper is movable. To reduce the rate at which the upper surfaces of the contacts are worn away by movement of the wiper, a non-conductive filler is deposited between the conductive materials which form the lands.
