Abstract: A wing having a winglet that provides a trailing-edge injection effect through a set of air outlets along the trailing-edge of the wing. The air flow is passively supplied by inlets formed at the leading edge of the wing that ingest air during flight, and directed to the outlets by ducts. The air flow may also be actively supplied by tapping into the engine bleed lines already in the wing of the aircraft. The trailing-edge injection effect reduces vortex drag, resulting in fuel savings in the operation of the aircraft.

Abstract: In described embodiments, a receiver includes a clock and data recovery (CDR) module with a voltage control oscillator (VCO) and a Sigma-Delta modulator in an integral loop control of the VCO. Providing finer resolution by the Sigma-Delta modulator reduces quantization noise in the integral control loop when compared to a loop without a Sigma-Delta modulator in the integral loop. Sigma-Delta modulation within the integral loop control of a VCO-based CDR reduces effective quantization of the VCO integral word control, allowing the proportional loop control compensation to i) reduce effective quantization of the VCO integral word control and, ii) enhance receiver jitter tolerance in presence of periodic-jitter, serial data whose frequency is offset from the nominal rate and serial data whose nominal frequency is modulated by a spread spectrum clock.

Abstract: Described embodiments provide a method and system for signal compensation in a SERDES communication system that includes monitoring the quality of a data signal after passing through a transmission channel. The quality of the data signal is monitored with at least one of a BER calculation algorithm and a received eye quality monitoring algorithm. Variations in channel length of the transmission channel are compensated for by i) adjusting a length of transmission line delay of the data signal from the transmission channel, ii) comparing the data signal quality with a threshold for the adjusted data signal; and iii) repeating i) and ii) until the data signal quality meets the threshold.
