Abstract:
A stand-alone device for navigating in a space having at least three dimensions comprises a housing capable of being manipulated by a user. The housing houses means for generating signals that represent the inclination of the housing according to its pitch axes, rolling axes and yaw axes, and houses at least one isometric device that generates a control signal of a bi-directional displacement according to at least one axis of said space. The invention is used, in particular, for navigating in a virtual space.
Abstract:
The present invention relates to a device for detecting the orientation of a solid including a sensor of angular position, capable of being affixed to the solid and of supplying at least a measuring datum representative of the orientation of the solid. The device also includes means for generating test data representative of an estimated orientation of the solid, and means for modification of the estimated orientation of the solid by confrontation of the measuring datum and test data.
Abstract:
The invention concerns a system, and its method of implementation, to determine the concentration of a substance mixed with a fluorophor and contained in one or more contacts of a matrix of contacts; it comprises: a microscope (1) associated with a magnifying objective lens (2) and with image acquisition means (4,5) to achieve a microscope image of the fluorescence of one of the contacts of the matrix or part of this contact; illumination means (11, 13) emitting a first beam to enable image acquisition in white light of said contact, and a second beam to excite the fluorophor contained in said contact; deflector means (15) for the second beam to ensure point by point scanning of the contact of the matrix; recording means (6, 7) to record the contact image; and processing means (6,7) of this image to quantify the fluorescence of the contact and determine the concentration of the substance.
Abstract:
The invention relates to a computer-aided prerecorded-music-interpretation system. The system comprises at least one musical actuator (A1, A2) actuatable by an interpreting artist user, memory means for storing musical information (MM) relating to the score of a piece of music to be interpreted by the user, and means for transmitting the musical information to an electronic/computerized device (A4) adapted for producing audio signals on the basis of the musical information received. The memory (MM) for the musical information defines the totality of the musical events (EM) constituting the piece of music to be interpreted. The invention is usable in the field of prerecorded-music interpretation.
Abstract:
A set of sensors is placed on a form (a curve or a surface), wherein each sensor supplies representative signals of the orientation of the form at the position of this sensor; a model of the form is selected; based on the signals, the parameters of the model are determined and the distances which separate the sensors are measured; and, based on the parameters of the model and the distance measurements, the spatial distribution of the points of the form are determined.
Abstract:
The process comprises acquisition of experimental data from measurements of physical quantities by means of at least one sensor associated to the object. The process comprises a first reliable estimation of a first range of values with a first method. The process comprises at least one additional estimation of an additional range of values with a different method. The methods each present a predetermined reliability. The ranges of values are successively observed in order of decreasing reliability of the corresponding methods. Each additional range of values is compared with the range of values corresponding to the previous method according to said order. The additional range is chosen as result when the additional range is comprised in the range corresponding to one of the previous methods.
Abstract:
Apparatus and method for measuring friction forces. According to this invention that is particularly applicable to mats for the prevention of skin lesions, a set of three-dimensional force sensors (10) is used, distributed on one face of a support (4). Each sensor outputs signals representative of a force applied by an object (6) on this sensor. Electronic processing means (16) determine components of forces applied on the sensors by the object and also output the relative tangential velocity of at least one point on the object that is in contact with one of the sensors and, advantageously the point at which the component of the force applied by the object on this sensor and normal to the face of the support, is a maximum.
Abstract:
The invention relates to a method for measuring the output power produced in a device having a crankset, including the following steps: a) measuring the orthogonal force (F) exerted on at least one pedal (9) of the crank (3); b) determining the angular velocity of the crank; and c) deducing the tangential force (FT) exerted on the crank and the power, using a pre-established model of the distribution of the force exerted on the actuating member as a function of the angular velocity,
Abstract:
Musical rendition is provided through the use of microsensors, in particular of accelerometers and magnetometers or rate gyros, and through an appropriate processing of the signals from the microsensors. In particular, the processing uses a merging of the data output from the microsensors to eliminate false alarms in the form of movements of the user unrelated to the music. The velocity of the musical strikes is also measured. Embodiments make it possible to control the running of mp3 or wav type music files to be played back.
