  • Patent number: 10173576
    Abstract: A first lamp assembly has a first attachment surface, a first transparent surface, a first side surface extending from the first transparent surface to the first attachment surface, and a first lighting member positioned to emit light through a portion of the first side surface. A second lamp assembly has a second attachment surface, a second transparent surface opposite the second attachment surface and a second side surface extending from the second transparent surface to the second attachment surface. The second side surface has a first projection extending therefrom that defines a first light deflecting surface such that when the second side surface and the first side surface are adjacent to one another with the light deflecting surface and first lighting member being aligned, the first light deflecting surface reflects and disperses light in a first area between the first lamp assembly and the second lamp assembly.

  • Publication number: 20160216300
    Abstract: The present disclosure provides a method and a phase lock detection apparatus for detecting whether a phase of an output signal is locked to the phase of a reference signal. The apparatus includes a first divider that individually frequency-divides first and second pulse signals, a phase frequency detector that outputs third and fourth pulse signals that correspond to a phase difference between the frequency-divided first and second pulse signals, a second divider that individually frequency-divides the third and fourth pulse signals, and a determiner that determines whether a phase of the second pulse signal is locked, based on the frequency-divided third and fourth pulse signals.
