International Classification:

H01L 33/00

US Classification:

257 98, 257 88, 257 93, 257 99, 257100

Abstract:

In accordance with the invention, a light emitting diode package assembly is provided to emulate the pattern of light produced by an incandescent filament bulb. The package assembly is composed of a substrate for LEDs comprising a heat-sinking base having a pair of opposing major surfaces. Each major surface has an overlying of thermally conducting ceramic and an outer surface layer of light reflective material. Disposed on each surface layer is a plurality of LEDs. Advantageously, the LEDs are arranged on the surface in a configuration of low mutual obstruction. Advantageously, reflecting elements transverse to each surface layer are positioned and shaped to reflect a substantial portion of the light emitted from the LEDs that would otherwise enter neighboring LEDs. In a preferred embodiment, the LEDs are arranged in the general form of a closed curve, and a transverse reflector is disposed in the interior of the curve. Alternatively, the LEDs can be arranged in a linear array.

Abstract:

Various systems and methods are described for performing fractionally spaced time domain equalization (TEQ). One embodiment is a method implemented in a communication system for training a fractionally spaced time domain equalizer (TEQ). The method comprises performing an initialization phase, averaging a received signal in the system to reduce effects of noise in a channel, determining a channel estimate, and aligning an ideal reference signal with the received signal. The method further comprises updating a target response filter according to a non-integer multiple of a base sampling rate, determining an adaptation error based on useful information both inside and outside a Nyquist band of the TEQ, and updating the TEQ according to the adaptation error.
