Semiconductor materials including a gallium nitride material region and methods associated with such structures are provided. The semiconductor structures include a strain-absorbing layer formed within the structure. The strain-absorbing layer may be formed between the substrate (e.g., a silicon substrate) and an overlying layer. It may be preferable for the strain-absorbing layer to be very thin, have an amorphous structure and be formed of a silicon nitride-based material. The strain-absorbing layer may reduce the number of misfit dislocations formed in the overlying layer (e.g., a nitride-based material layer) which limits formation of other types of defects in other overlying layers (e.g., gallium nitride material region), amongst other advantages. Thus, the presence of the strain-absorbing layer may improve the quality of the gallium nitride material region which can lead to improved device performance.
摘要:
An automatic vehicle headlamp dimming system which includes an optical system and an imaging processing system. The optical system is configured to discriminate between headlamps and tail lamps, and focus the light rays from the headlamps and tail lamps on different portions of a pixel sensor array. The optical system as well as the image processing system provides for relatively increased discrimination of headlamps and tail lamps of other vehicles and also enables the high beam headlamps of the control vehicle to be controlled as a function of the distance as well as horizontal angular position of other vehicles relative to the controlled vehicle.
摘要:
A swim raft constructed of a three-dimensional shaped body exhibiting a substantially planar bottom, a curved side, and a sloping top. The body has an outer shell constructed of a polyester laminate shell material and which encapsulates an inner foam core. At least one decorative indicia is associated with the sloping top and includes an artificial grass applied over and across a predetermined area associated with the top. The decorative indicia further includes at least one structural object projecting from the sloping top selected from such as a flag pole, a miniaturized lighthouse and an artificial palm tree.
摘要:
A radiation emitting device of the present invention includes at least one radiation emitter, first and second electrical leads electrically coupled to the radiation emitter, and an integral encapsulant configured to encapsulate the radiation emitter and a portion of the first and second electrical leads. The encapsulant has at least a first zone and a second zone, where the second zone exhibits at least one different characteristic from the first zone. Such different characteristics may be a physical, structural, and/or compositional characteristic. Preferably, the at least one different characteristic includes at least one of the following: mechanical strength, thermal conductivity, thermal capacity, coefficient of thermal expansion, specific heat, oxygen and moisture impermeability, adhesion, and transmittance with respect to radiation emitted from the radiation emitter. The radiation emitter may be in a form of an emitter, and is preferably an LED.

A semiconductor optical radiation package includes a leadframe, at least one semiconductor optical radiation emitter, and an encapsulant. The leadframe has a heat extraction member, which supports the semiconductor optical emitter and provides one or more thermal paths for removing heat generated within the emitter to the ambient environment, as well as at least two electrical leads for providing electrical coupling to the semiconductor optical radiation emitter. The encapsulant covers and protects the emitter and optional wire bonds from damage and allows radiation to be emitted from the emitter into the ambient environment. The semiconductor optical radiation package provides high emitted flux and is preferably compatible with automated processing techniques.
摘要:
A resilient, laminated polishing pad for chemical mechanical polishing is disclosed. The polishing pad includes a base layer and a polishing layer bonded by a hot-melt adhesive. The hot-melt adhesive of the present invention provides a Tpeel strength for the polishing pad of at least greater than 40 Newtons at 305 mm/min, reducing pad delamination.

The body of a road stud has oppositely directed presented faces each of which includes a central portion in which reflective elements are disposed and outer protective skirt portions which are inclined to the horizontal at a smaller acute angle than the central portion and project outwardly beyond the central portion.
摘要:
A method for using a portable display station is disclosed. First, a portable display station with at least a main device support, a support arm connected to the main device support, and a base connected to the support arm may be provided. The method may include securing a first display device to the main device support and stabilizing the portable display station. The step of stabilizing the portable display station may include positioning at least a portion of the base under a weighted object.
