Abstract: A runway performance monitor and method for an aircraft, includes providing a control, and monitoring aircraft performance. The control has baseline performance data of the aircraft during takeoff and/or landing. The control compares actual performance of the aircraft during takeoff and/or landing with the baseline performance data and calculates predicted information relevant to takeoff velocity and/or landed velocity. The control may determine braking point data and/or takeoff point data for that aircraft as a function of aircraft performance and runway location and length. The braking point data defines a location relevant to decelerating of the aircraft to a landed velocity. The takeoff point data defines a location relevant to accelerating of the aircraft to takeoff velocity. A display may be provided to display the information relevant to takeoff velocity and/or landed velocity.

Abstract: An active matrix liquid crystal display assembly including a flex circuit for interfacing substantially all of the row and column address lines of the display panel with a display output controller. The flex circuit is preferably made of two planar sheets laminated to one another, the first flex circuit sheet interfacing the row address lines with the display output controller and the second sheet interfacing the column address lines of the active matrix with the controller. The flex circuit includes a plurality of extension members, each extension member being electrically adhered to a driver TAB mounted to a peripheral side of the display panel.

Abstract: An LCD heater includes a substantially transparent ITO heating layer deposited on a transparent glass rear cover sheet, the ITO layer being mounted adjacent a planar surface of the display's rear polarizer. The ITO layer has a pair of substantially parallel flex circuit buss bars adhered thereto, the buss bars being sandwiched between the rear polarizer and the ITO heater layer.

Abstract: An integrated monolithic electrooptical component having an electrooptical modulator and a semiconductor laser on the same substrate. The modulator and laser are formed from a stack of semiconductor layers. The modulator includes one layer that is absorbent and the laser includes one layer that is active. Both absorbent and active layers are constituted by the same epitaxied structure of a highly coupled composition superlattice with alternation of semiconductor layers of different compositions. A forward voltage is applied to the laser layers that causes the active layer of the laser to emit a radiation which then traverses the absorbent layer of the modulator. A reverse voltage is applied to the modulator layers in order to modulate the absorption of the radiation traversing the modulator.

Abstract: An electro-optical component defined by a substrate which is coated in the growth axis direction with a periodic stack of semiconductor layers suitable for defining a superlattice whose quantum wells are fairly strongly coupled together. By applying a control electric field to the superlattice parallel to its growth axis, the optical absorption threshold is varied, and the direction of variation is towards higher energies.

Abstract: An Electro-Optic modulation method and device using a low-energy oblique transition of a tightly coupled super-grid. According to the present invention, a luminous beam is injected into a tightly coupled super-grid and an electric field (E) is applied to the super-grid whose amplitude is made to gradually vary so as to cause the intensity of the beam to vary. This beam is injected parallel to the plane of the films of the super-grid which guides the injected beam. The electric field is weak and applied along the growth direction of the super-grid, which provokes the appearance of a low energy oblique transition (TB) in a domain of wavelengths where the super-grid is transparent in the absence of any electric field. The super-grid is one whereby the wavelength of the luminous beam is contained in this domain. Such a device may find application in optical telecommunications systems.

Abstract: To detect a temporal variation, in particular an ultrashort pulse, in a beam of electromagnetic radiation, this beam is applied to a super-lattice of type II, along its axis of growth, and the voltage between the opposite sides of the network along the same axis is determined. The super-lattice is preferably a composite super-lattice, in particular, with alternate layers of indium arsenide and of gallium antimonide. The method is, in particular, applied in the infrared range.

Abstract: To optimize the operation of an installation for the manufacture of clinker, which installation comprises a rotary tubular kiln having an open discharge end for the clinker produced in the kiln, a cooler for the clinker connected to the discharge end, a hood covering the open discharge end and the cooler, hot clinker falling from the open discharge end into the cooler in a downward direction and cooling air passing in the cooler through the hot clinker and heated by the hot clinker, and a burner mounted in the hood and extending into the open discharge end of the rotary tubular kiln, the calorific energy radiated by the falling hot clinker is measured across the atmosphere of the hood to establish a control value, the measured control value is compared with a predetermined reference value for the radiated calorific energy, and at least one operating parameter of the installation is controlled in response to the difference between the control and reference values.
