Abstract: A method and structure are provided for implementing manufacture of a printed circuit board (PCB) with one of an infrared (IR) reflective mask or a novel solder mask to minimize coefficient of thermal expansion (CTE) mismatch between PCB laminate and plated through hole (PTH) copper. At least one of an IR-reflective mask and a solder mask composition for use in IR reflow processes is created such that radiant heat is reflected away from the major portion of the PCB yet permitted to impinge upon the PTHs. The copper within the PTH expands due to radiant heating while the bulk laminate expansion is significantly reduced due to the reflected IR radiation. Consequently, the CTE mismatch is minimized and tensile strain of the copper in the PTH is reduced, providing enhanced reliability.

Abstract: A cable connector for counting a number of plug-in events and preventing further plug in attempts after a threshold number of plug-in events have occurred. An inner sleeve is located inside an outer sleeve, and is designed to move relative to the outer sleeve. The inner sleeve further includes a tab on an outer surface of the inner sleeve. A gear wheel is located inside the outer sleeve and perpendicular to the inner sleeve and has a number of gear teeth. A toggle plug counter rotates the gear wheel one tooth in response to a plug-in action of the cable counter. When the gear wheel rotates to a point where the tab aligns with a notch in the gear wheel an inner spring at the opposite end of the inner sleeve causes the inner sleeve to move through the gear wheel such that further plugging action becomes difficult.

Abstract: A latch assembly includes a lever arm affixed to a latch pivot point of rotation with a cam having a connecting slot. A load mechanism is configured to apply a force on the latch pivot point to retain the lever arm in a first position. The load mechanism is tuned to apply the force along a tolerance range of operation of the latch assembly.

Abstract: A heat transfer device includes a base and a heat sink coupled to the base. The heat sink includes a fin with a surface for receiving a cooling medium to travel across, thereby defining an upstream end and a downstream end for the fin. An airflow projection is coupled to the surface of the fin, in which the airflow projection includes an upstream end and a downstream end with the downstream end of the airflow projection cantilevered above the surface of the fin.

Abstract: A microfluidic control apparatus, such as a relief valve, includes a pressure containing housing to contain a fluid within an interior of the pressure containing housing, and a nanotube in fluid communication between the interior of the pressure containing housing and an exterior of the pressure containing housing. The nanotube is used to contain water therein such that, below a predetermined temperature, the water within the nanotube prevents pressure relief through the nanotube from the interior to the exterior of the pressure containing housing, and above the predetermined temperature, the water within the nanotube enables pressure relief through the nanotube from the interior to the exterior of the pressure containing housing.

Abstract: A method, system and computer program product for improving discernment between qubit states in superconducting quantum computers. Channels are calibrated to train the kernel to contain the correct calibration data (“kernel states”). After calibrating a channel, testing is performed in which quantum operations are performed on qubits at the same time in adjacent channels, including the recently calibrated channel, to determine if the kernel response differs from the expected kernel response, where the expected kernel response is based on the kernel states of the trained kernel of the recently calibrated channel, beyond a threshold value. If such a situation occurs, then the phase of the signal for the recently calibrated channel is shifted and the process of recalibrating the channel (using the phase shifted signal) and testing is repeated until the difference between the kernel response and the expected kernel response is not beyond the threshold value.
