An airship deployment system comprises an airship of unique shape having laminar flow over this shape to enable low power propulsion, capable remote control, comprising an inflatable body; a propeller assembly for station keeping and repositioning said airship and capable of being folded into a compacted position and unfolded into an operational position; and a payload, comprising gas for inflating said inflatable body; and means for transferring data between said airship and a remote location; ...

The invention relates to a solar altitude detector (1) for motor vehicles comprising a shade mask (2) in which a passage opening (5) provided for permitting sunlight though is inserted, said opening creating a light structure when irradiated. A sensor array (3) comprising a plurality of individual pixels is representively arranged under the shade mask (2) such that individual sections of the light structure created by the passage opening (5) fall on the photosensitive surface of the sensor array...

Visual altitude alerting indicator for the altimeter of an aircraft, manually settable at "Before Landing Check List" to alert the pilot through visual cues to the required safe altitudes he must remember to prevent flying below prescribed safe altitudes, and to the altitude where the pilot must apply power to level when landing. The indicator requires no electronic assistance or audio alarms that might confuse the pilot over the many audio alarms presently used on aircraft. The alerting indicat...

An approximation is made in the equation for the desired vertical profile command signal to control the altitude of a drone traveling towards a target such that simple analog circuitry may be utilized instead of complicated computers.

A method and apparatus for allowing an individual to adjust to high altitudes is taught. The invention teaches the use of a small portable breathing gas control system to adjust the gas concentrations going to the subject's mask. This allows the subject to gradually adjust to high altitudes by breathing through this system during sleeping or other quiet activities.

The drive for the indicator mechanism of an altimeter is connected so as to drive altitude marker means, the relative position of such marker means being indicative of altitude. The marker means has a marker which may be implemented by a slot formed therein to reference this position. Sensor means is mounted in proximity to and for movement relative to the marker means. The sensor means is manually set to a position relative to the marker means by means of an altitude alert setting device, the s...

Disclosed is a communication device and method for estimating a more accurate vertical position or altitude of a communication device using atmospheric pressure measurements. In one embodiment, a first communication device comprises a pressure sensor for measuring local atmospheric pressure at the first communication device and a transceiver for communicating with a second communication device, wherein the transceiver may be operable to receive barometric calibration information for calibrating ...

A ground-based system for simulating dynamic suborbital-flight environments occurring during substantially complete suborbital-flights by a flight vehicle.

An differential expansion system and method for balloon buoyancy control which includes a zero-pressure envelope and a superpressure envelope. A gas transfer device is positioned between the envelopes to facilitate the transfer of lift gases that are lighter than air between the envelopes. The superpressure envelope and the gas transfer device can be located inside the zero-pressure envelope. Alternatively, the zero-pressure envelope, the superpressure envelope, and the gas transfer device can b...

An apparatus, method and computer program product for suppressing an alert generated by a terrain awareness system rotary wing aircraft of potentially hazardous proximity to terrain also reduces nuisance warnings and provides a terrain display consistent with the unique performance capabilities of such aircraft.
