Abstract:
A fiber optic control device having a joy stick lever (10), a housing (14, 16) which mounts the joy stick lever (10) for universal pivotal movement on the housing (14, 16) from an upright axis thereof, a pair of mirrors (42, 72) which are movably mounted on the housing, driving connections between the joy stick lever (10) and the mirrors (42, 72), for actuating the latter in response to movement of the joy stick (10) a cooperable movement limiting device on said joy stick (10) and housing (14, 16) enabling said universal pivotal movement of the joy stick lever (10) to be had while preventing its rotative movement about the longitudinal axis thereof, and fiber optic light transmission devices (24, 26, 54) that are cooperable with the mirror and that can include source of light which are adapted to direct light beams against portions of the mirrors (42, 72), for providing output light signals in optical cables, which are a function of the virtual position of the joy stick lever (10).
Abstract:
The present disclosure relates to laser systems and laser pulse measurement methods. The method comprises a dispersive system for applying a controlled chirp, to an incoming ultrashort light pulse to be measured; an optical system for selecting an homogeneous part of the transverse spatial beam profile of said light pulse; applying different spectral phases to different spatial parts of the beam obtained in the previous step, which comprises allowing different spatial parts of the beam to cross different thicknesses of material; focusing or propagating the beam in a nonlinear medium after applying the spectral phases; applying a nonlinear process to the pulse to be characterized for each spatial part of the beam, allowing the generation of a nonlinear signal for each spatial part of the beam; measuring the corresponding bi-dimensional data set that has the information on the nonlinear signal generated for each applied spectral phase in a detector; applying a numerical iterative algorithm to the measured data set to retrieve the spectral phase of the pulse to be characterized; such process being done in a parallel fashion.

Abstract:
An input device (10), to provide input to a computer system, includes a body (12) defining multiple fluid channels (26). A movable element (28) is located within each of the fluid channels (26) so as to be movable and responsive to a fluid flow through the respective fluid channel (26). A light sensor (38) is furthermore associated with each movable element (28), such that movement of the movable element (28) varies an intensity of light to which the respective light sensor (28) is exposed. The input device (10) generates an input signal in accordance with the intensity of the light to which at least one light sensor (38) of the input device (10) is exposed.
Abstract:
Methods and systems for modulating a manufactured light source are disclosed. Methods and systems of the present disclosure include sensor assemblies having first and second light sensors to retrieve light spectrum data at a target location, such as from a surface in an interior space at a home, office, or commercial building, that also receives daylight exposure. The first light sensor retrieves the light spectrum data within a spectrum of the manufactured light source. The second light sensor retrieves light spectrum data outside of the spectrum of the manufactured light source, yet within the spectrum of daylight. The light spectrum data is used to define spectral characteristics at the target location, such as a ratio of daylight to the manufactured light source, phase of daylight, and average overall quantity, which are used to maximize light-associated benefits of the spectral composition for the occupants at the target location, such as humans, plants, and animals.
