Title: Bi-level flow generator
Inventor: DELACHE ALAIN J
IPC: A61M16/00
Filed: 2001-09-28
Granted: 2011-11-15
Abstract: An apparatus and method for treating sleep apnea includes a bilevel flow generator having an alternating current (AC) synchronous motor coupled to a low inertia centrifugal rotor/impeller. The process of acceleration and deceleration of the rotor involves moving from frequency A, amplitude A to frequency B, amplitude B in an optimal linear fashion using the so-called Bresenham algorithm. This is coupled with a tuned increase of the amplitude during the acceleration process which will produce the acceleration using minimum current allowing the use of smaller power supplies. During deceleration the process is accomplished in reverse fashion using a tuned decrease of the amplitude coupled with a special shunt circuit to prevent power supply voltage changes. These changes in amplitude overlay a current feedback mechanism used to prevent loss of synchronization of the motor by changing amplitude. Speed changes can also be timed so as to prevent desynchronization.

Title: Steering system for articulated vehicles
Inventor: WILDEY ALLAN J
IPC: B62D6/00
Filed: 2003-09-12
Granted: 2010-08-17
Abstract: A steering system for an articulated vehicle has a microprocessor connected to a proportional solenoid valve which controls the direction, amount and rate of flow of hydraulic fluid to and from hydraulic articulation cylinders, which provide articulation between the frames of the articulated vehicle. A positional feedback sensor measures the angle of articulation between the frames and communicates the angle of articulation to the processor. A gear sensor monitors the gear that the vehicle is in and communicates it to the processor. A user input device allows a user to select the desired level of steering sensitivity and also allows the user to input the size of the tires installed on the vehicle. A steering device allows the operator to provide steering input and communicates electrical steering signals to the processor based on the steering input from the operator. The processor controls the valve to provide the steering response selected by the operator, to emulate castoring so that the vehicle is returned to a straight ahead position in the center position of the steering device, to vary the stop angle based on the tire size and to gradually stop articulation at the stop angle, to gradually start and stop articulation so as to avoid hydraulic hammering. If the steering valve has a source of supply which is common to other valves of the hydraulic system, the processor can also control all of the valves to give priority to the steering valve. In addition, the interface between the steering device and the processor is the same for different types of steering devices, i.e., a steering wheel or a joystick, so that different types of steering devices may be easily provided, depending on a customer's request.
