  • Patent number: 11181626
    Abstract: The present disclosure generally relates to laser range finders. In one embodiment, a shallow-trench isolation diode operates in a reverse-biased mode. In another embodiment, a poly-defined diode operates in a forward-biased mode. In both embodiments, the diode emits photons in response to a radio frequency current, and the photons are received by an avalanche photo diode during a calibration process.

  • Patent number: 10874024
    Abstract: A system or structure subject to external mechanical dynamic loading excitations propagated within the system or structure comprising a fluid filled structure and a fluid volume operable to facilitate fluid flow about at least part of the structure. Excitations within the structure can be propagated throughout. The system can further comprise a tuned mass damper (TMD) located within the fluid volume. The TMD can leverage the viscous properties of the fluid to attenuate the excitations within the structure. The TMD can comprise a mass and a spring operably connected to the mass. The TMD can further comprise a fluid resistance facilitating fluid flow about the mass and the spring for damping and a secondary tuning device operably connected to at least one of the mass and the spring and the supporting fluid-filled structure.

  • Patent number: 10451715
    Abstract: Embodiments of the present disclosure use an “on chip” silicon LED to generate a light signal for calibration of a range finder. The light signal from the silicon LED may be detected by photo detectors in a reference path and a receive path of the range finder to generate a calibration phase offset, which may be subtracted out from a phase offset measurement of the range finder to correct the phase offset measurement for component mismatch due to, for example, environment, process variation, aging, etc.

  • Patent number: 9553038
    Abstract: An apparatus for cooling semiconductor elements uses heat exchangers to transfer heat from the semiconductor elements to a coolant flowing through the heat exchangers. A central body, made from a flexible material, is positioned between the heat exchangers and a manifold from which the coolant is provided. The central body includes a plurality of flexible runners fluidly coupled to each heat exchanger and the manifold to provide the coolant to the heat exchanger. Heat is transferred away from the semiconductor elements by the coolant and heated coolant is returned from the heat exchanger to the manifold. Each flexible runner is configured to flex to conform to a height of a respective semiconductor element and thereby apply a force to the heat exchanger to maintain contact with the semiconductor element.
