Abstract: An isolation device having first and second semiconductor is disclosed. The first semiconductor die may be adapted to transmit a first signal to the second semiconductor die that is electrically isolated. The second semiconductor die may have a receiver having a counter and a control circuit. Each of the first and second semiconductor dies may have a clock generator respectively adapted to generate substantially similar clock frequency in order to transmit or to receive the first signal. In addition, an isolation system and a DC-DC feedback regulation control system having such first and second clock generators are disclosed. Likewise, a method for conveying a first signal across an isolation barrier is disclosed. The method may comprise generating a first clock signal for transmitting the first signal and generating a second clock signal for receiving the first signal.

Abstract: In one embodiment, an optical device having a first and second group of the plurality of sensors is disclosed. The first and second group of the plurality of sensors may have a first and second center of gravity region respectively. The plurality of sensors may be arranged such that the first and second center of gravity region may be substantially overlapping so as disturbances created by a time varying field on the first and second group of the plurality of sensors may be substantially similar in magnitude. In another embodiment, a fiber optic transmission system having first and second groups of the plurality of sensors being arranged around a center of gravity region is disclosed. In yet another embodiment, an optical transceiver having first and second sets of the plurality of sensors arranged such that center of gravity of each group is formed at the center region is disclosed.

Abstract: In one embodiment, a light-emitting device having a substrate, a casing, a plurality of light source dies, a plurality of spectral converters and a plurality of optical structures is disclosed. The spectral converters may be configured to spectrally adjust a portion of the light output of the light source die into a first and second converted spectral output that is substantially different from one another. In another embodiment, a system for illumination having a plurality of lighting assemblies has been disclosed. Each of the lighting assemblies comprises a light source die and a spectral converter. The spectral converter is configured to spectrally adjust the light output of the light source die so that the plurality of lighting assemblies are configured to emit substantially different spectral output. In yet another embodiment, a lighting apparatus having a primary spectral converter and a secondary spectral converter is disclosed.

Abstract: In one embodiment, a light-emitting device having a body, a reflector, a light source die, and a spectral converter is disclosed. The spectral converter may be formed adjacent to, but distanced away from, the light source die. The spectral converter may be configured to spectrally adjust a portion of the light output having a predetermined spectral content. In another embodiment, a system for illumination having a plurality of lighting assemblies is disclosed. Each of the lighting assemblies comprises a spectral converter configured to spectrally adjust a portion of the light output so that the plurality of lighting assemblies are configured to emit substantially similar spectral output. In yet another embodiment, a lighting apparatus having the spectral converter is disclosed.
