  • Patent number: 11939036
    Abstract: A device for coupling a propulsor to a marine vessel. A rail is configured for attachment to the marine vessel. A carriage is moveable relative to the rail into first and second positions. A shaft has a first end pivotally coupled to the marine vessel and a second end for coupling to the propulsor. An actuator is configured to pivot the shaft relative to the marine vessel to thereby move the propulsor into and between stowed and deployed positions. A lock is manually operable to fix the carriage in the first position in which the actuator prevents manual pivoting of the shaft and alternatively in the second position in which the shaft is permitted to be manually pivoted.

  • Patent number: 6933535
    Abstract: A structure includes semiconductor light emitting device and a wavelength converting layer. The wavelength converting layer converts a portion of the light emitted from the semiconductor light emitting device. The dominant wavelength of the combined light from the semiconductor light emitting device and the wavelength converting layer is essentially the same as the wavelength of light emitted from the device. The wavelength converting layer may emit light having a spectral luminous efficacy greater than the spectral luminous efficacy of the light emitted from the device. Thus, the structure has a higher luminous efficiency than a device without a wavelength converting layer.

  • Patent number: 6307218
    Abstract: A light emitting device includes a heterojunction having a p-type layer and an n-type layer. The n-electrode is electrically connected to the n-type layer while the p-electrode is electrically connected to the p-type layer. The p and n-electrodes are positioned to form a region having uniform light intensity.

  • Patent number: 5233204
    Abstract: A light emitting diode (LED) including a light generation region situated on a light-absorbing substrate also includes a thick transparent layer which ensures that an increased amount of light is emitted from the sides of the LED and only a minimum amount of light is absorbed by the substrate. The thickness of the transparent layer is determined as a function of its width and the critical angle at which light is internally reflected within the transparent layer. The thick transparent layer is located either above, below or both above and below the light generation region. The thick transparent layer may be made of materials and with fabrication processes different from the light generation region.

  • Patent number: 5204284
    Abstract: A high band-gap opto-electronic device is formed by epitaxially growing the device section in a lattice-matched (Al.sub.x Ga.sub.1-x).sub.y In.sub.1-y P-GaAs system. The band-gap of the epitaxial layer increases with x. Instead of growing the device section directly on the GaAs substrate, a layer of (Al.sub.x Ga.sub.1-x).sub.y In.sub.1-y P, graded in x and in temperature while maintaining substantially y=0.5, is grown as a transitional layer. The high band-gap device structures include homojunctions, heterojunctions and particularly a separate confinement quantum well heterostructures. Various embodiments of the invention include devices on absorbing substrates and on transparent substrates, and devices incorporating strained-layer superlattices.

The band-gap of the epitaxial layer increases with x. Instead of growing the device section directly on the GaAs substrate, a layer of (Al.sub.x Ga.sub.1-x).sub.y In.sub.1-7 P, graded in x and in temperature while maintaining substantially y=0.5, is grown as a transitional layer.

  • Patent number: 5008718
    Abstract: A light-emitting diode has a semiconductor substrate underlying active p-n junction layers of AlGaInP for emitting light. A transparent window layer of semiconductor different from AlGaInP overlies the active layers and has a lower electrical resistivity than the active layers and a bandgap greater than the bandgap of the active layers, for minimizing current crowding from a metal electrical contact over the transparent window layer. The active layers may be epitaxially grown on a temporary GaAs substrate. A layer of lattice mismatched GaP is then grown on the active layers with the GaP having a bandgap greater than the bandgap of the active layers so that it is transparent to light emitted by the LED. The GaAs temporary substrate is then selectively etched away so that the GaP acts as a transparent substrate. A transparent window layer may be epitaxially grown over the active layers on the face previously adjacent to the GaAs substrate.
