  • Patent number: 9438347
    Abstract: In one aspect, an optical media converter is provided for use within aircraft data networks. In one example, the optical media converter converts electrical doublet signals to optical Manchester signals, and vice versa. In an illustrative example, the optical media converter includes a receiver circuit coupled to a fiber optic port for receiving a Manchester-encoded input signal using an edge-coupled filter that filters out signals not associated with edges within the time-varying input signal Manchester signal. The optical media converter also provides, for example, for high common mode rejection and includes logic to correct for bit-width skew. The optical media converter is well-suited for use in converting doublet signals generated by a serial interface module of a line replaceable unit of an ARINC 629-compatible system into optical Manchester signals for transmission over a fiber optic bus system interconnected by a star coupler.

  • Publication number: 20160223831
    Abstract: An eyeglass apparatus comprises left and right eyeglass portions and a link. The link is configured to permit the eyeglass apparatus to transition between an extended configuration and a collapsed configuration. In the extended configuration, the eyeglass apparatus is adapted to be worn by a user in a conventional eyeglass wearing orientation. In the collapsed configuration: an inwardly facing lens face of one of left and right lenses faces an outwardly facing lens face of the other of the left and right lenses; a medial edge portion of the left lens is closer to a medial edge portion of the right lens than to a lateral edge portion of the right lens; and the lateral edge portion of the left lens is closer to the lateral edge portion of the right lens than to the medial edge portion of the right lens.

  • Publication number: 20160018669
    Abstract: An eyeglass apparatus comprises first and second eyeglass portions, each having a connector portion and a lens portion. The eyeglass apparatus is configured to transition between stowed and extended configurations. When the eyeglass apparatus is in the stowed configuration, the lens portions overlie one another. When the eyeglass apparatus is in the extended configuration, the lens portions are in a non-overlying configuration.

  • Publication number: 20150282454
    Abstract: A pet grooming tool is provided with a fur ejector portion that is at least partially movable relative to the teeth of the pet grooming tool and can be manually moved into engagement with fur that is wedged or lodged between the teeth. The engagement of the fur ejector portion with the fur forces the fur from the gaps between the teeth. Preferably, the fur ejector portion can be manually moved by the same hand a person uses to support and hold the grooming tool.
