A system and method for assisting a pilot to recover the aircraft from a variety of dangerous situations involving one or more of the following: altitude, airspeed, attitude, roll rate, and a partial equipment failure in the control panel. In accordance with the invention, these factors are sensed automatically, and voice instructions are provided to the pilot to direct him or her to get the aircraft out of the dangerous situation sensed by this system.

A cushioning conversion machine and method for converting sheet stock material into a cushioning dunnage product and wherein the tension in the stock material is controlled to avoid problems associated with improper tension. A conversion assembly draws the stock material from a stock supply and converts the stock material into a strip of cushioning, and a controller controls the operation of the conversion assembly. The conversion assembly is powered by a motor and the controller controls the op...

A cushioning conversion machine (20) including conversion assemblies (24) which convert a sheet stock material into a relatively low density cushioning product. The conversion assemblies (24) include a feed/cut assembly (26) having a feed device (100), a cut device (200), and a drive device (300). The drive device (300) is operable in two opposite directions and alternately drives the feed device (100) and the cut device (200). Clutch (134) and/or clutch (234) are provided which allow reverse op...

A method is disclosed for checking model planes entering into a dive, as well as an anti-dive method and apparatus. The method of checking planes includes installation of a first optical sensor in the upper part of the plane, with installation angle upwardly intersecting with the front of the plane at .alpha. degrees, that checks light intensity and outputs a first checked optical signal; installation of a second optical sensor in the bottom part of the plane, with its installation angle downwar...

Methods and computer program products are provided for controlling a plurality of control effectors of an aerodynamic vehicle based upon the mode shape direction of one or more structural modes excited by actuation of the control effectors. For example, control of the actuation of the control effectors may be provided to emphasize actuation of those control effectors that affect a structural mode having a mode shape direction that is substantially orthogonal to the mode shape of the structural m...

A novel cushioning conversion machine and method for converting sheet stock material into a novel cushioning product and for producing discrete sections or pads of desired length, without the need for a cutting assembly, thereby enabling the construction of a less expensive, smaller and less complex machine. The machine and method are characterized by a weakening device for perforating a sheet stock material of one or more plies along tear lines so that as a strip of cushioning is formed from th...

A device to assist in the piloting of an aircraft includes a display unit to present, in a display window of a screen, an information presentation illustrating a vertical plane along a flight path which represents a flight plan and which is formed so as to position the display window altitude-wise, and to further position a symbol illustrating the aircraft vertically in the display window, where the positioning of the display window and the symbol are based on the current flight phase, the curre...

A device to assist in the piloting of an aircraft in free flight includes a display unit to present, in a display window of a screen, an information presentation illustrating a vertical plane and which is formed so as to position the display window altitude-wise, and to further position a symbol illustrating the aircraft vertically in the display window, where the positioning of the display window and the symbol are based on the current flight phase, the current altitude and the current value of...

A cushioning conversion machine and related methodology characterized by one or more features including, inter alia, a feeding/connecting assembly which enables an operator to easily vary a characteristic, for example the density, of the cushioning product; a feeding/connecting assembly wherein input and/or output wheels or rollers thereof are made at least in part of an elastomeric or other friction enhancing material, which reduces the cost and complexity of the input and output rollers; a man...

A calibration system for ccalibrating orientation parameters of a digital optoelectronic sensor system includes an attitude and position determining system arranged in a mobile carrier, such as an airplane or a satellite, for determining the orientation parameters in flight. An optoelectronic component emits light in a defined direction with respect to the mobile carrier. A planar optical detector is arranged relative to the optoelectronic device for detecting the reflection of radiation emitted...
