| Number | Title | Issue Date |
| 6772976 | Sensor for measuring wind angle A differential pressure-induced airflow based approach is used to measure Angle-Of-Attack (AOA) or Angle-Of-Sideslip (AOS) for an aircraft. Ports on opposing sides of an aircraft fuselage are coupled by an airway incorporating a mass airflow sensor. As the relative ... | 08/10/2004 |
| 6766761 | Firehose coupling exit indicator An indicator device captured between couplers of ends of firehose sections that point to the source of the firehose and to safety. The preferred embodiment includes gasket-like annular body which fits over the male threads of the male coupler and is captured between... | 07/27/2004 |
| 6032087 | Ship position control system A bowthruster is operated by a control unit with wind direction based on a detection signal from vane-anemometer. A bow in a hull attitude is slightly adjusted so as to direct a bow of the hull to windward. At the same time, a propulsion unit is operated ... | 02/29/2000 |
| 5811673 | Wind direction indicator A wind direction indicator is disclosed having a rotatable wind vane 1 and a support 10 for connection to the mast of a yacht. The vane 1 is connected to the support 10 by means of a gimbal mechanism 6-9 and a stabilizing weight 4 is connected to the gimb... | 09/22/1998 |
| 5127358 | Apparent wind direction indicator Masthead device for sailboats that indicates apparent wind direction composed of a rotating wind vane and a protractor arm encompassing multiple reference marks. These marks can be adjusted with greater compass accuracy to allow several settings in each q... | 07/07/1992 |
| 4790255 | Wind and boom direction indicating device There is provided a device useful for adjusting the main sail of a sailboat said device being equipped with apparent wind indicating means and color coded means for indicating desirable position for the boom of said main sail; said device being used alone... | 12/13/1988 |
| 4774835 | Method for laminar boundary layer transition visualization in flight Disclosed is a method of visualizing laminar to turbulent boundary layer transition, shock location, and laminar separation bubbles around a test surface. A liquid crystal coating is formulated using an unencapsulated liquid crystal operable in a temperat... | 10/04/1988 |
| 4646567 | Wind indicator for sailboat A wind indicator for a sailboat has a wind vane on a vertical shaft which is mechanically coupled with a horizontal shaft turning a pointer. The wind angle relative to the boat is indicated by the pointer on a circular dial. Two windward pointing indicato... | 03/03/1987 |
| 4567760 | Flow direction and state indicator The subject indicator is a lightweight conical or cone-like member attached to a test surface at its apex by a flexure pivot. The indicators are useful, in a range of sizes, for providing visual indication of the direction and state of fluid flow past the... | 02/04/1986 |
| 4561301 | Miniature wind sock assembly A miniature wind sock assembly adapted to be coiled and inserted into a small plastic display container. The wind sock is supported on a spring mast in turn fixed to a spring base bracket that is designed to be attached either to standard bicycle handleba... | 12/31/1985 |
| 4522069 | Windvane A plexiglass or similar plastic windvane that has beveled peripheral edges or is otherwise provided with surface markings from which light rays impinging thereon exit from the plexiglass causing illumination of the edges or markings, whereby the windvane ... | 06/11/1985 |
| 4468961 | Fluid direction meter suitable for angle of attack meter for aircraft Presented is a method and means for monitoring the angle of attack of an airfoil and displaying the monitored angle of attack as a visual reference to the pilot.... | 09/04/1984 |
| 4437425 | Air flow direction indicator An airflow direction indicator in accordance with the invention is intended for sailboards, in which the front portion of the sail includes a tunnel which is slipped onto the mast and is rotatable relative thereto when varying the sheeting and curvature o... | 03/20/1984 |
| 4314477 | Sailboat wind direction indicator A wind direction indicator for a sailboat includes a mounting bracket for mounting on the forestay of a sailboat with a support frame extending forward of the mounting bracket and including a generally Y-shaped wire frame with the arms of the Y serving as... | 02/09/1982 |
| 4230290 | Airplane angle of attack and direction of flight indicator An airplane angle of attack and direction of flight indicator includes a vane on the outside of the fuselage which is pivotally movable in response to changes in the airplane's angle of attack. A group of optical fibers are supported within the airplane w... | 10/28/1980 |
| 4227406 | Wind direction device A wind direction device for attachment to a boat shroud for indicating the direction of the wind relative to the direction of travel of the boat. The device includes several wraps of adhesive tape around a boat shroud to form an upwardly facing shoulder a... | 10/14/1980 |
| 4223631 | Sailing indicator The sailing indicator assembly is constructed to space the tail from the sail and to maximize the force effect of a light wind to keep a wet tail from sticking to the sail. More particularly, the inner end of the tail is mounted to a spacer member, the in... | 09/23/1980 |
| 4080826 | Apparent wind indication device A device for mounting on a sailboat to provide a visual indication of the optimum boat-to-wind angle to achieve maximum distance per unit of time to windward. A pivotally mounted wind vane includes a pair of flexible struts extending outwardly at equal an... | 03/28/1978 |
