  • Publication number: 20140047918
    Abstract: A time-domain inertial sensor comprising: a support structure having an electrode plane parallel to an x-y plane of an x-y-z mutually orthogonal coordinate system, wherein the support structure's largest dimension lies within the x-y plane; a proof mass having a first surface parallel to the x-y plane; wherein the proof mass is springedly coupled to the support structure such that the first surface is separated from the electrode plane by a gap; a driver configured to drive the proof mass to oscillate with respect to the support structure in approximately only the x-direction such that, while oscillating, the gap does not vary significantly; and a first, time-domain, proximity switch disposed to switch from an open state to a closed state each time the proof mass is in a first reference position with respect to the support structure.

  • Publication number: 20120237789
    Abstract: A metal-clad polymer article includes a polymeric material with or without particulate addition. The polymeric material defines a permanent substrate. A metallic material covers at least part of a surface of the polymeric material. The metallic material has a microstructure which, at least in part, is at least one of fine-grained with an average grain size between 2 and 5,000 nm and amorphous. The metallic material has an elastic limit between 0.2% and 15%. At least one intermediate layer can be provided between the polymeric material and the metallic material. A stress on the polymeric material, at a selected operating temperature, reaches at least 60% of its ultimate tensile strength at a strain equivalent to the elastic limit of said metallic material.

  • Patent number: 7972051
    Abstract: Described are a backlight, a backlight assembly for use in an electronic device and an electronic device configured to activate the backlight's first light source and to activate the backlight's second light source independently of one another. The described double-sided backlight may illuminate either the primary display or the secondary display. The disclosed backlight includes two light sources, each used to direct light in opposite directions from the double-sided backlight. The light guide of the backlight is configured to direct light from the first light source in a first direction to exit the light guide via its first face, and to direct light from the second light source in a second direction different from the first direction to exit the light guide via its second face.

  • Patent number: 7818135
    Abstract: An apparatus and method for timing calibration of write and read-back data exchanges between respective dies of an external memory/external device has a master arbiter or, alternatively, a test bus between a system bus master interface and an external memory controller for driving the external memory/external device, a calibration circuit under control of the master arbiter via a test bus master interface to provide stepped-through time delays for test data exchanges between the dies, and the calibration circuit obtains pass/fail data indicating pass or fail of the varied time delays for the test data exchanges. A processor system at the system bus master interface selects calibration values corresponding to pass data, and applies the calibration values to the respective dies for timing of write and read-back data exchanges between the dies.
