Abstract: A fluid dispenser device comprising: a body (10); an elongate flexible strip (20) supporting a plurality of reservoirs (21), each containing a dose of fluid or powder; reservoir-opening means (30) for opening a respective reservoir on each actuation; and displacement means (40) for displacing said flexible strip (20) before and/or during and/or after each actuation, so as to bring a full reservoir into register with said reservoir-opening means, the leading end (25) of said flexible strip (20), in the displacement direction of said strip, rolling up around a receiver element (50) that does not turn relative to said body (10).

Abstract: An optical code reading device, including a unit having, for each of the tracks of the coded element, a pair of photodiodes, a differential amplifier receiving the outputs of the photodiodes and the trigger connected to the output of the amplifier, a shift register receiving the outputs from the unit, a control unit, a clock and apparatus for feeding to said unit signals adapted for simulating at will, for each channel, the bit level "0" or the bit level "1".

Abstract: An analog position indicating optical encoder is provided including: an element (1) with a band (2) having a transparency which substantially is complete with respect to two wavelengths (1.sub.1 and 1.sub.2) but varies as a function of the angular or linear distance for a third wavelength (1.sub.3) at wavelength which is between the above-said two wavelengths (1.sub.1 and 1.sub.2); light emitting means (3.sub.1,3.sub.2,3.sub.3) emitting three light beams (7.sub.1,7.sub.2,7.sub.3) at the above said wavelengths (1.sub.1,1.sub.2,1.sub.3); a first optical coupler (5,6) mixing the beams (7.sub.1,7.sub.2,7.sub.3); optical bidirectional transmission means of the optical fiber type (B); a second optical coupler (18,19) dividing into three beams (20.sub.1,20.sub.2,20'.sub.3) the light leaving the means (B) after being reflected by the optical element (13) and after passing through the band (2); three readers (23.sub.1,23.sub.2,23.sub.3) responsive to the wavelength (1.sub.1,1.sub.2, and 1.sub.

Abstract: A position locating optical coder is provided formed by a sensor which includes a reader, for reading a code carrying element a pivoting micromirror actuated under the control of the output of the reader and a self contained power supply source. A module is provided which comprises two light emitters, a second reader, a unit for processing the signals from the second reader, and a power supply source. In addition a bidirectional coupler and optical fiber transmitting devices serve to transfer the code pulses between the sensor and the module.

Abstract: An optical position locating apparatus is provided which includes a first light reader with several photodetectors for reading the tracks of a disk, a first light emitter excited by the first light reader and a self contained power supply source. A module is provided which comprises a second light emitter, a second light reader and a processor for processing electric signals from the first light reader. An optical fiber system is provided for transmitting the electric signals to the second light reader. Optical systems are advantageously provided.

Abstract: An optical position locating device is provided comprising a light emitter, a bidirectional optical coupler, an optical fiber, a series of micromirrors disposed between a fiber and disk carrying the coded tracks (one mirror opposite each track). A control unit successively brings one and only one mirror into an active position, the others remain in a rest position. An optoelectronic reader emitting a light pulse in response to the light reflected by one of the mirrors in the active position through the optical fiber and and a processing unit processes these signals.

Abstract: An analyzer for noise signals which are transmitted by a telephone pair in a telephone cable is connected to a digital transmission equalizer. A delimiting circuits delimits the binary stream generated by the threshold detector into data packets such that each stream is considered to be a unique packet as long as the stream does not comprise a predetermined number of zeros. At predetermined instants, writing is triggered into a random access data memory to store the contents of a schedule data register, of a storage register and of a frame unique word register. The time base also comprises an output connected to an incrementing input of an address counter and to an output connected to the zero reset input of storage register.
