Abstract
The invention provides an optical particle sensor (1) comprising:
- at least one light source (2, 2r, 2g, 2b) configured to emit light rays (20),at least one channel (3) intended to receive a fluid transporting at least one particle (30), and to at least partially receive the light rays (20) emitted by the at least one source (2, 2r, 2g, 2b), such that said light rays (20) are partially scattered by the at least one particle (30),at least one photodetector (4) capable of receiving said scattered light rays (20),said sensor (1) being characterised in that the at least one source (2, 2r, 2g, 2b) has an emission face (21) facing one side (D) of the sensor and in that the at least one photodetector (4) has a receiving face (41) facing the same side (D) of the sensor (1), such that the light rays received by the at least one photodetector are light rays (20b) backscattered by the at least one particle (30), for at least 90% of them.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
