Abstract: Disclosed is a device and a method for storing and transporting at least one human or animal tissue with a view to transplantation or ex vivo experimentation. The device can store such tissue in a specific storage medium until the transplantation or the ex vivo experimentation, and in particular to storing a sample of human or animal cornea, such as a corneal graft. This device for storing at least one human or animal tissue comprises at least one chamber which is suitable for receiving and storing the tissue in a liquid storage medium and which comprises means for continuous renewal of the medium in said at least one chamber. The device additionally comprises means for adjusting at least one physicochemical parameter of said medium, including its pH, by continuous circulation of a buffer gas in said at least one chamber outside of and in contact with said medium.

Abstract: Cork stoppers are treated by subjecting the cork to an electrochemical dehalogenation by electrolysis.

Abstract: A detector system for detecting a chemical substance, the system being of the type comprising a measurement sensor for selectively sensing the chemical substance to be detected, and a measurement unit associated with the measurement sensor for the purpose of being connected to a processor unit to determine whether said chemical substance for detection is present or absent. The measurement sensor comprises an olfactory neuron selected for selectively sensing the chemical substance to be detected, and the olfactory neuron is secured to a support in order to co-operate with the measurement unit.

Abstract: A method for measuring the location of an object in an observed space by means of a fixed observation system connected to a processing unit for generation of an image comprising a pixel matrix, the object being provided with a test marker. The test marker comprises a periodic pattern in two dimensions and a digital processing of the image of the test marker is carried out to produce an image comprising a first grating and an image comprising a second grating which are analyzed digitally to calculate the position of the test marker within the matrix of pixels.

Abstract: The invention concerns an electronic label (2) designed to be affixed on an article, the label comprising a central unit (5) including storage means (8) wherein are stored an identification code of the label and temporal data related to the article storage and also a time clock (7) and comparison means (9) for comparing the recorded temporal data with the time information supplied by the clock, the label further comprising communication means (4, 15). The central unit (5) is adapted to activate the communication means (4, 15) to transmit a warning message to an external device (1) when the time information supplied by the clock are in predetermined relationship with the recorded temporal data.

Abstract: The invention relates to a hearing aid device in which the slices (s.sub.1, x.sub.2) of the electrical signal corresponding to each acoustic signal comprised respectively between 1500 and 3500 Hz and between 5000 and 7000 Hz, are transposed into compensation signals (S.sub.1, S.sub.2) comprised within two coupled ranges of separate low frequencies above the range 60 to 800 Hz, alone preserved without compensation. To preserve the timbres of the transposed sounds, the compensation signals are obtained by multiplying each slice (x.sub.1, x.sub.2) by itself or by a signal (x'.sub.1, x'.sub.2) deduced from this slice by amplitude equalization.
