Palladium-based ternary or higher alloys include palladium at about 45-55 wt %, copper about 32-42 wt %, silver at about 8-15 wt %, rhenium at about 0-5 wt %, and optionally one or more modifying elements at up to 1.0 wt %. The alloys are age-hardenable, provide hardness in excess of 350 HK (Knoop, 100 g load), have electrical conductivities above 19.5% IACS (International Annealed Copper Standard), have an elevated temperature strength above 100 ksi at temperatures up to 480 F. (250 C.), and remain ductile (tensile elongation >2%) in their fully age-hardened condition. The alloys may be used in static and moveable electrical contact and probe applications.

The temporal and spatial distributions of pressure across the roll-workpiece interface during the micro- form-rolling process are critical indicators for the quality of the formed textures. This paper presents a novel method for monitoring the pressure distribution through a set of capacitive sensors embedded within the roll. Numerical and analytical models of the sensor-embedded roll have been established for determining the optimal sensor dimension to maximize the capacitance output in the pico-Farad range, under space constraint. A transfer function of the sensor is established for retrieving the pressure distribution. The technique is evaluated by simulation and confirmed through experiments. © 2012 CIRP.

Electrically-assisted micro-rolling (EAμR) takes advantage of localized heating by loading current through the deformation zone to enhance the texturing capability of Ti-6Al-4V and AA3003-H14. The challenge to achieve a desired deformation pattern is the lack of reliable models to capture the often non-uniform mechanical and thermal behaviors. In this paper, pressure distributions are measured by a custom-designed, tool-embedded sensor. Furthermore, the effects of current on texturing are first characterized using a coupled mechanical and thermal model. Comparison between modeling and experimental results confirmed the effectiveness of EAμR on texturing and the importance of multi-physics modeling. © 2014 CIRP.


An antimicrobial composite includes a polymeric support and at least one transition metal mounted onto the support surface. The transition metal may be silver, and the support material may be a non-reactive plastic such as polyethylene or polypropylene. The composite may be encapsulated by a permeable or porous outer layer. Preparation of the composite may involve mixing an aqueous salt solution containing the transition metal with the support in the presence of a surfactant, precipitating the metal onto the support, and reducing the metal to its elemental state. The resulting composite in which the polymeric support surface includes the elemental metal is useful in the treatment of water and ice to inhibit or prevent microbial growth.

An electrical connection apparatus includes an electrical connection contact and an adjustment component within an interior of the electrical connection apparatus. The electrical connection contact is operatively coupled to the adjustment component so that the electrical connection contact adjusts between an insertion position and a contact position in response to rotating the adjustment component. A slider may be movably arranged within the interior of the electrical connection apparatus to cause the electrical connection contact to move in response to rotation of the adjustment component. The electrical connection apparatus may include stackable blocks coupled to each other so that the adjustment component, electrical contact and slider, when provided, are arranged within an interior of the coupled stackable blocks.

Apparatuses and methods for fuel level sensing are described herein. An example sensor may include a sealed housing and an electrically conductive coil. The sealed housing may comprise a pivot end, a float end opposite the pivot end, and an interior defined by walls extending therebetween. The pivot end may be adapted to join a pivot point and the float end may be adapted to join to a float at an exterior of the housing. The electrically conductive coil spring is disposed in the housing interior and comprises a first end and a second end opposite the first end. The coil spring is adapted to expand and retract in response to movement of the internal float within the housing and to electrically couple to a circuit configured to sense a change in resistance in the coil spring in response to expansion and retraction of windings of the coil spring.

Apparatuses and methods for fuel level sensing are described herein. An example sensor includes a sealed housing comprising a first end, a second end, and an interior defined by walls extending therebetween. The sensor includes a float surrounding an exterior of the sealed housing and is configured to move longitudinally along the sealed housing between the first end second ends. The float may include a magnetic element configured to provide a magnetic field. The sealed housing may include an electrically conductive spring coupled to at least one of the first end or the second end, and may include a ferrous element coupled to the electrically conductive spring and configured to be displaced relative to the sealed housing based on the magnetic field. The electrically conductive spring may expand and retract to adjust a resistance of the electrically conductive spring in response to the ferrous element being displaced.

Apparatuses and methods for fuel level sensing use a rotatable housing, an interior arm suspended on an axle within the housing, a counterweight joined to one end of the interior arm and a position sensor with first and second sensor elements. The sensor elements are arranged within the housing with one of the sensor elements is joined to an interior wall of the housing and the other joined to the interior arm such that the sensor elements are rotatable relative to one another. An exterior arm joined to an exterior of the housing is adapted to accommodate a float. The exterior arm slaves the rotatable housing in rotation about a rotational axis, and relative rotation of the first and second sensor elements may cause a change in a sensor output of the position sensor.

Apparatuses and methods for fuel level sensing use a rotatable housing configured to rotate about an axis based on a fuel level. Within the rotatable housing is a roller ball sensor assembly including a resistive trace having a plurality of portions, a conductive trace and a conductive element. The roller ball sensor assembly is configured to provide a resistance indicative of a rotation of the rotatable housing about the axis by using the conductive element to electrically couple a portion of the plurality of portions corresponding to the resistance to the conductive trace.
