International Classification:

B64C 27/615

US Classification:

416 23

Abstract:

A helicopter rotor blade that has a blade body and a control flap secured to the blade body. The rotor blade has a first primary mover capable of generating a first linear motion that is sufficient to generate a high amplitude, low frequency motion of the control flap; and a second primary mover capable of generating a second linear motion that is sufficient to generate a small amplitude, high frequency motion of the control flap. Further, the rotor blade has a coupling transmission for combining the first linear motion with the second linear motion that generates a cumulative linear motion; and a second transmission device that causes the cumulative linear motion to rotate the control flap.

International Classification:

F01D 7/00

US Classification:

416 23, 244 1711

Abstract:

A helicopter rotor blade having a blade body that defines a confined space and a control flap that is secured to the blade body that moves through a range of motion. An electric machine is secured inside of the rotor blade body that rotates a motor shaft. A transmission device is secured to the motor shaft and the control flap that transfers rotary motion of the motor shaft to the control flap to generate movement of the control flap through its range of motion. The transmission device remains substantially within the confined space throughout the range of motion.

International Classification:

G02F 1/13

US Classification:

349187

Abstract:

A method of fabricating a liquid crystal display device by introducing a ferroelectric liquid crystal (FLC) between two substrates, contacting the FLC to a molecularly smooth edge, and aligning the FLC by introducing a temperature gradient normal to the edge. In one embodiment, the FLC is aligned by cooling it from an isotropic phase to a smectic phase at a rate that is relatively slow. For example, the cooling rate may be less than about 3 degrees Celsius per hour. In one embodiment, smectic layers are formed that are parallel to the edge. In one embodiment, the molecularly smooth edge is an air bubble.

International Classification:

F02C 6/18

US Classification:

700288

Abstract:

A controller for controlling a combined heat and power (CHP) system which can include one or more CHP units, can comprise a high level optimizer and one or more low level optimizers. The high level optimizer can be configured to optimize a total cost of producing heating, cooling, and electric power, by allocating total heating, cooling, and/or electric power setpoints one or more CHP unit types, based on the fuel price, CHP unit operational constraints, and/or heating, cooling, and/or electric power demand. The low level optimizer can be configured to allocate cooling, heating, and/or electric power setpoints to individual CHP units, based on the high level allocation to CHP unit types.

Appl. No.:

8/718199

Inventors:

Michael G. O'Callaghan - Erie PA

Assignee:

MR Technologies - Girard PA

International Classification:

F16D 3702

US Classification:

60326

Abstract:

An adjustable magneto-rheological fluid device includes a movable piston adjacent a first chamber containing a first hydraulic fluid for moving the piston. The first hydraulic fluid interacts with a flexible magneto-rheological compartment containing a magneto-rheological fluid that flows between a first magneto-rheological fluid chamber and a second magneto-rheological fluid chamber. By controlling the flow of the magneto-rheological fluid, the device controls the first hydraulic fluid in the first chamber to bias the piston in a first direction. Additionally, the magneto-rheological fluid device may include a second chamber, containing a second hydraulic fluid, spaced apart from the first chamber on the opposite side of the piston. The second hydraulic fluid interacts with the flexible magneto-rheological compartment allowing the device to control the second hydraulic fluid to bias the piston in a second direction opposite the first direction.
