The use of anti-friction ball bearings in a unique arrangement does not require the use of lubricating oil from the internal combustion engine lubricating system and permits close coupling of the bearings and a compact turbocharger. A turbocharger bearing housing forms a coolant jacket with an inner bearing engaging portion that has two bearing engagement surfaces engaged with the outer races of two anti-friction bearings whose inner races carry rotating shaft, turbine and compressor of the turbocharger. The anti-friction bearings are, preferably, angular contact ball bearings, and the two bearing engagement surfaces of the bearing housing are closely spaced, providing a turbocharger shaft of minimal length and substantially reducing the thermal expansion of the shaft. The coolant jacket protects the anti-friction bearings from exposure to the extreme heat of the exhaust gas driven turbine, notwithstanding their increased proximity due to the shortened turbocharger shaft. In addition, an external motor-generator may be carried by the compact turbocharger, and its motor may be connected to the turbocharger rotor assembly by a permanent, solid connector and stay connected throughout the entire operating range of the turbocharger. In such assembly, the electronic motor-generator control is mounted on the motor housing and energizes the motor from battery power during the engine acceleration period up to approximately the torque peak speed; thereafter, the control changes to a generator mode when excess energy is available in the engine exhaust gas.

A packaging system for a high current, low voltage power supply. The power supply uses bare die power FETs which are directly mounted to a thermally conductive substrate by a solder attachment made to the drain electrode metallization on the back side of the FETs. The source electrode and gate electrode of each FET are coupled to the circuitry on an overhanging printed circuit board, using CSP solder balls affixed to the front side of the FET die. The heat generated by the FETs is effectively dissipated by the close coupling of the FETs to the thermally conductive underlying substrate. High interconnect densities are achieved through the use of a multilayer printed circuit board. This high interconnect density, with the addition of a magnetic core element, allows the power supply packaging system to incorporate transformer windings for an isolation transformer or an inductor.

Electric arc spraying a metal onto a substrate produces an anchor layer on the substrate that serves as a surprisingly superior intermediate layer for a catalytic material deposited thereon.

A sensor, method and system, for measuring certain characteristics of a fluid. The sensor utilizes a piezoelectric device having at least two tightly coupled resonators providing a two pole electric transfer function responsive to an electrical signal coupled to the input resonator. The piezoelectric sensor has a textured entrapment layer, constructed to entrap a known volume of fluid and impart motion to the entrapped fluid as well as to surrounding non-trapped fluid. The common mode frequency shift of the two resonant frequencies is related to mass loading due to the entrapped fluid, while the energy absorbed by the fluid, or a phase shift of one of the resonant frequencies, is related to the viscosity / density product of the fluid. Extracting the viscosity is a matter of mathematical manipulation. By controlling the energy level of the input electrical signal, the viscosity measurement may be conducted at a predetermined shear rate.

A computer system architecture and memory controller for close-coupling within a hybrid computing system using an adaptive processor interface port (“APIP”) added to, or in conjunction with, the memory and I / O controller chip of the core logic. Memory accesses to and from this port, as well as the main microprocessor bus, are then arbitrated by the memory control circuitry forming a portion of the controller chip. In this fashion, both the microprocessors and the adaptive processors of the hybrid computing system exhibit equal memory bandwidth and latency. In addition, because it is a separate electrical port from the microprocessor bus, the APIP is not required to comply with, and participate in, all FSB protocol. This results in reduced protocol overhead which results higher yielded payload on the interface.

The invention discloses a method of state transition of steam control transmission protocol, which comprises the following steps: after a home terminal SCTP is coupled into SHUTDOWN-PENDING status and when the home terminal SCTP judges that data which is not sent exists in a sending buffer and the receiving window of an opposite terminal SCTP is larger than or equal to the length of the current first datum which is not sent, the home terminal SCTP sends the first datum which is not sent to the opposite terminal SCTP and starts a latency response timer Ta; when the latency response timer Ta is beyond a regular time and if the home terminal SCTP does not receive a response from the opposite terminal, SCTP coupling is closed. The method of the invention ensures that the coupling can be put into use quickly when the home terminal SCTP receives the request to close coupling from SHUTDOWN, the user of an upper level, and if data needs sending to the opposite terminal SCTP and data can not be sent successfully for a long time caused by small receiving buffer of the opposite terminal SCTP or other reasons.
