    摘要： An indicator return device for an electrical gauge which produces a reading when electrical power is supplied to it, but which requires means for producing torque to return its indicator to a zero or reference position when the gauge is disconnected from a source of electrical power. The indicator return device comprises a bimetallic strip attached to the gauge frame and a leaf spring also attached to the frame. A cam is attached to the shaft on which the gauge indicator is mounted. A resistance wire is wound around a portion of the bimetallic strip. When electrical power is supplied to the gauge, a current flows through the resistance wire. This heats the bimetallic strip causing it to bend, which then permits the leaf spring to move out of the path of movement of the cam. When the electrical power no longer is supplied to the electrical gauge, the bimetallic strip forces the spring into contact with the cam which, in turn, returns the gauge indicator to a desired reference position. The resistance wire may be made an operative element in the electrical gauge circuitry used to provide gauge indications.

    摘要： A voltage or current sensor containing a heater resistor, a first heat responsive resistor in intimate thermal contact with the heater resistor, a second heat responsive resistor in intimate thermal contact with the ambient temperature, and insulator means separating the heater resistor and first heat responsive resistor from the second heat responsive resistor. A voltage or current to be measured is applied to the heater resistor, which produces a heat output that is proportional to the true RMS value of current flow through the heater resistor. This heat output is transmitted to the first heat responsive resistor, whose resistance value varies as a substantially linear function of temperature within a temperature range corresponding to the range of voltages or currents to be measured. The thermal resistance between the heat resistor and the first heat responsive resistor is much less than the thermal assistance between the heater resistor and a temperature reference comprising the case and a heat sink. A second heat responsive resistor has the same or opposite temperature coefficient of resistance of the first heat responsive resistor, and its resistance also varies as a substantially linear function of temperature, but since it is insulated from the heator resistor and is in intimate thermal contact with the temperature reference, its resistance will be determined by the ambient temperature rather than by the temperature of the heater resistor. Therefore, the resistance ratio of the first and second heat responsive resistors is proportional to the heat output of the heater resistor, which in turn is proportional to the true RMS value of voltage or current applied thereto and compensated for ambient temperature variations.

    摘要： A cylindrical reflector, having an inner elliptical reflecting surface, is positioned in a coaxial line. A thin-film heater is connected to the center conductor of the line. The heater is located along one focal axis of the reflecting surface and the hot junctions of a thermopile are located along the other focal axis. Input current causes the heater to radiate infrared energy which is reflected and focused onto both sides of the hot junctions. The resulting electrical output of the thermopile is proportional to radiated power and consequently input current squared, and because of thermal compensation the output is substantially independent of ambient and self-heating temperature changes.

    摘要： Devices, systems, and methods for the selective positioning of an intravascular neuromodulation device are disclosed herein. Such systems can include, for example, an elongated shaft and a therapeutic assembly carried by a distal portion of the elongated shaft. The therapeutic assembly is configured for delivery within a blood vessel. The therapeutic assembly can include a pre-formed shape and can be transformable between a substantially straight delivery configuration; and a treatment configuration having the pre-formed helical shape to position the therapeutic assembly in stable contact with a wall of the body vessel. The therapeutic assembly can also include a mechanical decoupler operably connected to the therapeutic assembly that is configured to absorb at least a portion of a force exerted on the therapeutic assembly by the shaft so that the therapeutic assembly maintains a generally stationary position relative to the target site.
