Abstract: A process for selectively depositing a filled underfill material onto a die surface without covering solder bumps present on the die. The process entails microjetting a polymer matrix material, a filler material, and optionally a fluxing material onto the die surface. Together, the polymer matrix and filler materials define the filled underfill material in which the filler material is dispersed to reduce the coefficient of thermal expansion of the underfill material. The resulting underfill material surrounds but does not cover the solder bumps. The die is then placed on a substrate on which a second underfill material is present, forming a composite underfill layer that completely fills the space between the die and substrate and forms a fillet on a peripheral wall of the die.

Abstract: A twin spark ignition apparatus having two high-voltage (HV) outputs incorporates features for balancing load capacitance on each HV output. The ignition apparatus provides a first high-voltage (HV) connection configured for direct mounting on a first spark plug, and a second HV connection for coupling to a second spark plug by way of an HV cable. The HV cable adds capacitance at the second HV output, as compared to a direct mount. The secondary winding is shifted by a predetermined distance, relative to the primary winding, in direction toward the direct mount end of the ignition apparatus. The shifting reduces the internal load capacitance at the second end (top), so that when the capacitance added by the HV cable is considered, the respective load capacitances are balanced. The voltage variation between the two HV outputs is reduced.

Abstract: A method for providing supplemental internal air cooling to a multi-cylinder internal combustion engine. The method involves deactivating the fuel injector to one cylinder for a predetermined time period or temperature decrease, based upon engine operating conditions, and then reactivating the fuel injector. This results in cool air being pumped through the fuel-deactivated cylinder by the reciprocating action of the piston therein, which air-cools the walls, piston, and head of that cylinder from the inside. In response to a controlling algorithm in an Engine Control Module, various of the engine fuel injectors may be deactivated and then reactivated sequentially to provide distributed cooling over the entire engine. The invention is especially useful for motorcycle engines having two or more cylinders when the motorcycles are used at low or stop-and-go speeds, such as in parades or other ceremonial functions.

Abstract: A system utilizes a single receiver to simultaneously receive and demodulate both amplitude shift keying (ASK) messages and frequency shift keying (FSK) messages. The single receiver is used to demodulate the FSK modulated message and the single receiver provides a received signal strength indicator (RSSI) signal that provides an indication of a combined strength of the FSK and ASK messages. The RSSI signal is filtered and then data sliced to provide a digital message that corresponds to a demodulated version of the ASK modulated message.
