Abstract:
A fiber optic rotary joint and an associated reflector assembly are provided for supporting optical communications between a rotor and a stator. The fiber optic rotary joint includes at least one optical source carried by the rotor or the stator for transmitting optical signals. The fiber optic rotary joint also includes a reflector mounted upon the other one of the rotor and stator for reflecting the optical signals. Further, the fiber optic rotary joint includes a receiver for receiving the optical signals following their reflection. The reflector is generally shaped and positioned such that the path length along which the optical signals propagate from the optical source(s) to the receiver is equal, regardless of the rotational position of the rotor to the stator. The reflector may have a reflective surface shaped to define a portion of an ellipse and/or a reflective surface shaped to define a portion of a hyperbola.
Abstract:
A long life double layer capacitor (10) and method of making the same comprising a case (11) and a first terminal (28) with an electrically insulating hermetic seal interposed between the first terminal and the case. A first current collector foil (22) is electrically coupled to an interior portion of the first terminal and a first metal impregnated carbon cloth electrode (12) having a metal impregnated side which is juxtaposed against the first current collector foil. A porous separator (18) is then juxtaposed against the first metal impregnated carbon cloth electrode and separating the first metal impregnated carbon cloth electrode from a second metal impregnated carbon cloth electrode (14) having a metal impregnated side which faces away from the porous separator. A second current collector foil (24) is juxtaposed against the metal impregnated side of the second metal impregnated carbon cloth electrode and is electrically coupled to the second terminal (29). And an electrolyte solution (20) saturates the first and second metal impregnated carbon cloth electrodes and is substantially contained by the case and the electrically insulating hermetic seal such that an influx of impurities into the electrolyte solution is substantially inhibited by the case and the electronically insulating hermetic seal.
Abstract:
In one aspect, a foamable composition is disclosed, which comprises a base polymer, talc and a citrate compound blended with the base polymer. In some embodiments, the concentration of the talc in the composition is in a range of about 0.05% to about 25% by weight, e.g., in a range of about 2% to about 20%, or in a range of about 3% to about 15%, or in a range of about 5% to about 10%. Further, the concentration of the citrate compound in the composition can be, for example, in a range of about 0.05% to about 3% by weight, or in a range of about 0.02% to about 0.9% by weight, or in a range of about 0.03% to about 0.8% by weight, or in a range of about 0.04% to about 0.7% by weight, or in a range of about 0.05% to about 0.6% by weight.
Abstract:
Described herein are foamable compositions and methods of making foamed compositions. The foamable composition comprises at least one polymer and a foaming agent. The foaming agent comprises a talc or a talc derivative. The polymers described herein comprise a substantially non-halogenated polymer. One or more additives are added to render the compositions flame retardant and/or smoke suppressant. Also described are Power over Ethernet (PoE) cables, having at least one electrical conduit comprising an electrically conductive core, an insulation that at least partially surrounds said electrically conductive core and a polymeric separator extending from a proximal end to a distal end and having at least one channel adapted for receiving the at least one electrical conduit. The PoE cables are capable of carrying about 1 watt to about 200 watts of power.
Abstract:
A trim component such as a bezel for attachment to a trim panel, such as an instrument panel of a vehicle, is disclosed and includes one or more retention tabs (38) for securing the trim component to the trim panel. The retention tabs (38) provide for a plurality of limiting features that help in preventing a non-blunt contactable edge condition from occurring, particularly during an impact between the vehicle and another vehicle or object.
Abstract:
A fiber optic transceiver (37) is adapted for use in transmitting and receiving optical signals in a fiber-optic network (30). The improved transceiver comprising: a multi-mode optical fiber (36) having a longitudinal axis (x-x) and having a proximal end (35). The fiber is adapted to convey optical signals in either direction therealong. A photodetector (32) is arranged in longitudinally-spaced relation to the fiber proximal end. The photodetector has a sensitive surface (34) operatively arranged to receive light energy exiting the fiber through the proximal end. A light source (31) is arranged between the fiber proximal end and the photodetector surface. The light source is arranged to selective emit light energy into the fiber through the proximal end.
Abstract:
A method for the high-velocity compaction of a part from particulate material is disclosed. The method includes the steps of providing a cavity that is at least partially formed by at least one bottom punch, inserting a pre-form that includes at least two levels into the cavity and moving an energy controlled main ram toward the pre-form at a high velocity to increase the density of the pre-form and form the part. A multiple-level part from particulate material and a high-velocity compaction press are also disclosed.
Abstract:
A vehicle control device comprising a display module with a display on a front face of the display module, a touch-sensitive layer, and a transparent cover attached to the front face of the display module where a front face of the transparent cover has a tactile feedback area. A haptic feedback unit is configured to provide an active haptic feedback by moving or deforming the transparent cover. A control unit is configured to display a graphical user interface on the display to receive a user input via the touch-sensitive layer and to trigger a vehicle function in response to the user input.
