Title: Cold air super-charged internal combustion engine working cycle & method
Inventor: BRYANT CLYDE C
IPC: F02M31/04
Filed: 2004-03-10
Abstract: Working cycle for internal combustion engines, with methods and apparatuses for managing combustion charge density, temperature, pressures and turbulence (among other characteristics). At least one embodiment describes a supercharged internal combustion engine in which a supercharging portion of air is compressed, cooled and injected late in the compression process. A sub-normal compression ratio or low "effective" compression ratio initial air charge is received by a cylinder/compression chamber on the engine intake process, which during compression produces only a fraction of heat-of-compression as that produced by a conventional engine. During compression process, dense, cooled supercharging air charge is injected, adding density and turbulence above that of conventional engines with low "effective"  compression ratio for this portion of air charge also. Compression continues and near piston top dead center, the air charge being mixed with fuel is ignited for power pulse followed by scavenging.

Title: System for implementing a secondary game
Inventor: SCHNEIDER RICHARD J
IPC: G07F17/32
Filed: 2004-04-02
Abstract: The present system provides an incentive for players to place maximum wagers in an effort to gain access to secondary games, the entry of which is controlled by the player's own wager amount, wager type, or wager source. In employing such games, gaming machine establishments are able to maximize the level of play on each of their gaming machines and thereby reduce operation costs and increase the number of machines available for play. A secondary game is triggered in case the wager exceeds a predetermined threshold.

Title: Fault-tolerant computer and method of controlling same
Inventor: NIINO RYUTA
IPC: G06F11/16
Filed: 2005-12-20
Abstract: A fault-tolerant computer has duplex systems each comprising a CPU subsystem for controlling access to a CPU and a storage unit, and an IO subsystem for controlling data which are input to the IO subsystem from an external circuit and output from the IO subsystem to the external circuit.  Data with a transmission time assigned thereto is transmitted from one of the IO subsystems to the other IO subsystem, and is received asynchronously by the other IO subsystem. The other IO subsystem records a reception time of the data, and calculates an ideal reception time using the transmission time assigned to the data. A clock shift in the other IO subsystem with respect to the one IO subsystem is calculated from the calculated ideal reception time and the recorded reception time. Thereafter, the counter in the other IO subsystem is changed based on the calculated clock shift, and data is received using the changed counter.

Patent CA-2538447-A1 (CA)
Inventor: HARWOOD JONATHAN DAVID
IPC: H02P7/282
Filed: 2006-03-06
Abstract: A low noise electronic three phase bridgecontrolled brushless DC motor suitable for whiteware appliance pumps and other appliance applications. Back EMF zero crossing sensing is used to determine rotor position and thus stator winding commutation times. Motor torque and speed are controlled by pulse width modulating the operation of that bridge switching device which has just been switched from an OFF state to an ON state on each new commutation. All three stator windings have current flowing in each winding commutation to improve motor current waveform and thereby reduce motor noise, but the current in one winding is always terminated before the end of the commutation period to allow the back EMF in that winding to be sensed for zero crossing.

Abstract: An in vivo optical imaging system and method of identifying unusual vasculature associated with the angiogenic vasculature in tumors. An imaging system acquires images through the breast. Benign, noninvasive oxygen and carbon dioxide are used as vasoactive agents and administered by inhalation to stimulate vascular changes. Images taken before and during inhalation are subtracted. An optical vascular functional imaging system monitors abnormal vasculature through optical measurements on oxy- and deoxy~hemoglobin during inhalation of varying levels of O2 and CO2. The increase in contrast between tumor (cancerous) and normal (noncancerous) tissue is dramatic, facilitating accurate early detection of cancerous tumors and improving sensitivity and specificity (lower false negative and false positive rates). The invention is useful in mammography, dermatology, prostate imaging and other optically accessible areas.
