Abstract: Examples described herein relate to a method and a system for removing the common-mode current. The receiver includes a photodetector, a common-mode adjustment circuit, an analog front-end, an eye scan circuit, and a control unit. The photodetector generates an input photocurrent responsive to a received optical signal. The common-mode adjustment circuit generates an adjusted input current based on the input photocurrent. The analog front-end generates a differential voltage based on the adjusted input current. Based on the differential voltage, the eye scan circuit generates an eye scan information defining a first outer eye and a second outer eye in an eye diagram. The control unit tunes the common-mode adjustment circuit based on a relative height metric of a first height of the first outer eye and a second height of the second outer eye to remove a portion of the common-mode current from the input photocurrent.

Abstract: A dual cycle waste heat recovery system includes a high-temperature circuit that utilizes a first working fluid. The first working fluid is heated by a first waste heat source and then expanded through a first expander to produce power. The heat recovery system further includes a low-temperature circuit that utilizes a second working fluid. The low-temperature circuit also includes a first heat exchanger for heating the second working fluid with heat from the first working fluid and a second heat exchanger for heating the second working fluid with heat from a second waste heat source. A control valve selectively controls the flow of the second working fluid to each of the first and second heat exchangers according to a predetermined set of parameters. An expander receives the second working fluid from the first and second heat exchangers and expands the second working fluid to produce power.

Abstract: A regenerative brake system for converting kinetic energy of a moving vehicle into usable mechanical or electrical power is disclosed. The regenerative brake system includes a generator operably coupled to at least one of the vehicle wheels. The system further includes a battery and a thermal storage system, each of which stores power generated by the generator until it can be efficiently used. The thermal storage system includes a heater that uses electrical power from the generator to vaporize a working fluid disposed within a storage tank. The thermal storage system further includes an expander to selectively expand the vaporized working fluid to convert heat from the working fluid into usable energy.

Abstract: A test environment and an associated method of testing and analyzing a semiconductor package material containing a molding compound, for stability in a sustained oxygen environment. Test samples are exposed to a pressurized gas containing oxygen, under elevated temperature below the glass transition temperature of the molding compound. Control samples are exposed to a pressurized inert gas under similar or more severe conditions of gas pressure, temperature, and humidity. At least one characteristic common to the test samples and the control samples is measured. A determination is made as to whether there exists at least one significant difference between the at least one measured characteristic of the test samples and the control samples.

Abstract: A semiconductor structure fabrication method for removing a tape physically attached to a device side of the semiconductor substrate by an adhesive layer of the tape, wherein the adhesive layer comprises an adhesive material. The method includes the step of submerging the tape in a liquid chemical comprising monoethanolamine or an alkanolamine for a pre-specified period of time sufficient to allow for a separation of the tape from the semiconductor substrate without damaging devices on the semiconductor substrate.
