Abstract: An optical waveguide modulator with automatic bias control is disclosed. A dither signal is applied to the modulator bias and its signature detected in light tapped from an output of the modulator using a phase sensitive dither detector such as a lock-in amplifier. The detected signal is processed using pre-recorded information defining the direction of the detected signal change relative to a change in the modulator bias, and the bias is adjusted in the direction determined using the information. An IQ bias of a quadrature modulator is controlled by dithering bias settings of two inner modulators at different dither frequencies, and detecting an oscillation at a sum frequency.

Abstract: Work is produced from heat in a continuous cycle. A flow of first working fluid is provided to a high pressure boiler to produce a flow of first working fluid vapor. A second working fluid in vaporous form is compressed, after which a third working fluid is formed by mixing the first working fluid vapor and the second working fluid. Thermal energy is transferred directly between the first and second working fluids in the mixing chamber exclusive of any intervening structure. A refrigeration loop containing a fourth working fluid extracts thermal energy from a low grade thermal energy source and moves the thermal energy to the first working fluid and/or the second working fluid.

Abstract: One embodiment sets forth a timing calibration technique for on-chip source-synchronous, complementary metal-oxide-semiconductor (CMOS) repeater-based interconnect. Two transition patterns may be applied to calibrate the delay of an on-chip data or clock wire. Calibration logic is configured to apply the transition patterns and then trim the delays of the clock and data wires based on captured calibration patterns. The trimming adjusts the delay of the clock and data wires using a configurable delay circuit. Timing errors may be caused by crosstalk, power-supply-induced jitter (PSIJ), or wire delay variation due to transistor and wire metallization mismatch. Chip yields may be improved by reducing the occurrence of timing errors due to mismatched delays between different wires of an on-chip interconnect.

Abstract: A data connector includes two different sets of wires that transport data between components of a computer system. A first set of wires transports data from a first component to a second component. A second set of wires transports data from the second component to the first component. The first set of wires is interlaced with the second set of wires so that each wire in the data connector transports data in the opposite direction of one or more neighboring wires.
