Title: Electronic proportional regulation device for heating and/or air conditioning for a motor vehicle
Inventor: BRENIER HENRI
IPC: G05D23/19
Filed: 1986-12-19
Abstract: In order to heat and/or air condition a motor vehicle, a motor M acts on the position of at least one mixing member VM for the air blown into the passenger compartment HA. A generator GSE supplies a deviation signal DV from a set-point temperature TC as well as a signal for the temperature TA of the air blown in and for the passenger compartment temperature TI. The deviation signal DV is applied to two comparators CD and CI which allow the motor to be turned off or on in one or other direction, respectively, as a function of the deviation signal. The comparators operate in intermittent mode, with a square-wave control signal whose form factor and/or frequency increase with the amplitude of the temperature deviation.

Title: Method for equalizing the amplitude/frequency response of an electro-acoustic transducer assembly, corresponding transducer assembly
Inventor: ELOISE-PILLERAULT CLEMENT
IPC: H04R1/28
Filed: 1987-12-11
Abstract: The field of the invention is that of electro-acoustic transducers. The aim is to provide an equalization method, and more generally a method for correcting the restored signal, without affecting the output of the transducers. This aim is reached with a method using at least two transducers, the second transducer (2) being so selected as to have a response amplitude/frequency curve (C) which is substantially complementary to that (A) of the first transducer (1) in order to form by adding sound signals from said transducers a resulting corrected sound signal, due to the mutual compensation of irregularities inherent to each curve (A), (C). A preferred application of such electro-acoustic transducer system is the high power sound production in congress and concert halls, or more generally the provision of sounds in any place where a public event is held.
Patent FR-2610118-A1 (FR)
Title: 3-D stereoscopic device for television or slide projector
IPC: G03B35/26
Filed: 1987-01-23
Abstract: The device according to the invention makes it possible to pass, rapidly and without difficult manipulation, from the projection of flat images, to that of 3-D images, with a single projector or television projector. The invention employs stereograms consisting of two left-hand and right-hand images placed side by side, the light of each image being polarised at 90 degrees to the plane of polarisation of the other. The light from the two images projected is reflected towards the screen 20 by two mirrors 16, 17 placed side by side at a sufficient distance from the objective 15 for each mirror to reflect only one of the images of the stereoscopic pair; these mirrors are oriented so as to catch the optical axes in order to superpose the two images on the screen 20. The audience wear suitably polarised glasses. In order to return to flat projection, it is sufficient no longer to direct the projection onto the mirrors. The present invention allows image projection all the possibilities of 3-D.
