摘要： The present invention provides a method (600) and device (200,500) for providing temperature-stable optical feedback for optical packages. The device includes an optical emitter (202,502), a first partially reflective optical element (204, 504), a second partially reflective optical element (206,506), a first optical sensing unit (208,508), a second optical sensing unit (210,510), and a feedback unit (212). The optical emitter (202,502) is responsive to an electrical input current and generates a beam of light (214). The first optical sensing unit (208,508) and the second optical sensing unit (210,510) receive diffracted portions of the beam of light (214) from the first partially reflective optical element (204, 504) and the second partially reflective optical element (206,506) respectively and generate a first feedback signal E1 and a second feedback signal E2. The feedback unit (212) utilizing the first feedback signal E1 and the second feedback signal E2 adjusts the electrical input current to the optical emitter (202,502).

摘要： A method and apparatus is described herein for pulse shift modulation of output waveforms for reducing crosstalk on interconnects. Based on input pulses/bits, an output waveform is selectively delayed by a shift value to ensure transitions in a first direction occur in a first half of a period and transitions in a second direction occur in a second half of the period. When the same pulse shift modulation is implemented on surrounding traces, certain worst-case crosstalk scenarios are reduced; thus reducing crosstalk and increasing performance in power consumption and speed of data transfer.

摘要： Board delamination during the singulation from a board panel and board sagging during front-end assembly are two biggest problems encountered in cellular manufacturing lines. The method (700) and circuit board panel (600) of the present invention substantially eliminate assembly-line delamination and sagging for circuit board manufacturing. A number of slots are punched to fit into a circuit board profile. V-grooves are cut along each of the circuit board profiles through the slots and directly opposite on a top and bottom of the circuit board. Thus, optimization of the cut-outs and v-groove configurations eliminate tearing/delamination and substantially reduce sagging.
