Abstract: A method and apparatus for processing aerodynamic angles for an aircraft. A first rate of change in an inertial aerodynamic angle is calculated using data received from an inertial measurement system for the aircraft. Further, a second rate of change in an externally measured aerodynamic angle is calculated. Yet further, a filtered aerodynamic angle is generated during a flight of the aircraft using the first rate of change in the inertial aerodynamic angle and the second rate of change in the externally measured aerodynamic angle. Still further, a contribution of the first rate of change in the inertial aerodynamic angle used in generated the filtered aerodynamic angle is changed based on a difference between the first rate of change in the inertial aerodynamic angle and the second rate of change in the externally measured aerodynamic angle, enabling controlling the flight of the aircraft using the filtered aerodynamic angle.

Abstract: An adjustable reflector device for light fixtures is disclosed. The device comprises a reflector sheet made of a resiliently flexible material with at least one reflective surface folded and flexed along two parallel pivot axes into a concave arrangement of one central section and two flexible wings behind a high-intensity discharge lamp, such that the degree of concavity of the reflector can be adjusted to a plurality of predetermined degrees relative to the lamp by flexing or bending the wings radially around the pivot axes without the use of tools, thereby allowing horticulturists in the field to adjust the geometry of the light beam emitted in order to provide plants positioned below the fixture with a uniform pattern of light radiation of different intensities as needed at different stages of plant growth.

Abstract: Nitrated and non-nitrated compounds capable of protecting brain tissue from injury and useful as therapeutic agents to treat neurodegenerative diseases and conditions are disclosed. Methods of using the compounds in therapeutic treatments, and methods of preparing the compounds, also are disclosed.

Abstract: The present invention uses a reference voltage that varies within a Pulse Width Modulation (PWM) cycle to generate the PWM signal. This allows for stability in the feedback of Constant On-Time (COT) control for buck controllers when low Equivalent Series Resistance (ESR) capacitors are used as the output capacitor. The reference voltage is adjusted using features of a PWM cycle in a voltage mode without using external inductor current information.
