Abstract:
According to the invention, a set of sensors (4a) is placed on this shape (curve or surface), each sensor outputting signals representative of the orientation of the curve or the surface at the location of this sensor; a model of the curve or the surface is chosen; model parameters are determined from the signals; and the spatial distribution of the points on the geometric shape are determined using these parameters. The invention particularly applies to machining, joinery, masonry, and building domains.
Abstract:
Controlling playback by strokes entered via a MIDI interface or measured by one or more motion sensors is disclosed. The variations of the playback speed can also be smoothed to ensure a better musical rendition. The velocity of the strokes can also be taken into account to control the volume of the audio output and other gestures or strokes can also act on the tremolo or vibrato.
Abstract:
Process and acquisition device of a deformable geometrical form.A set of sensors (1) is placed on this 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. The invention applies especially to the fields of machining, joinery, masonry work and construction work.
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.

Abstract:
A capture device of the orientation of a solid comprising a sensor of angular position, capable of being affixed to the solid and supplying a measuring datum related to a real orientation of the solid, wherein the sensor is sensitive to gravity/magnetic field; calculation means for generating test data independent of any measuring datum and related to an estimated orientation of the solid; and means for modifying the estimated orientation by confrontation of the measuring datum and test data. A process including capturing a measuring datum related to a real orientation of the solid, the measuring datum originating from an angular position sensor sensitive to gravity/a magnetic field; establishing test data independent of any measuring datum and related to an estimated orientation of the solid; confronting the test data and the measuring datum; and establishing a new estimated orientation of the solid based on the result of the confrontation.
Abstract:
A method for measuring movement of a solid, using an absolute measurement associated with a double integration measurement. The method can be applied in particular to sensing movements of the human body and includes a series of measurement of the acceleration of the solid and double integration of the measurements to obtain successive values of a first translation of the solid, and a series of absolute measurements of at least one second degree of freedom of the solid, namely a rotation, and this measurement of rotation is converted into a measurement of translation used to update the first translation.
Abstract:
A method and system for measuring the output power produced in a device having a crankset, includes: measuring the orthogonal force exerted on at least one pedal of the crank; determining the angular velocity of the crank; and deducing the tangential force 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:
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.
